Definitions

  • the present invention relates to a grinding disc unit for a rotary grinding machine, as it is used for the production of fine surfaces, for example in the automotive, furniture, painting and plastics sector.
  • BE 855 087 A1 is a device with hollow pins made of hard metal for the mechanical Entlacken of surfaces known.
  • the hollow pins of the device are elastically attached and scrape in the sense of a wire brush paint from the surface to be painted.
  • the publication WO 2009/088772 A2 D1 describes adapters for grinding machines which are arranged between a sanding pad and a grinding wheel and which are intended to ensure the transport of dust between each grinding wheel and each sanding pad.
  • the publication EP 1 291 134 A1 describes a grinding plate for use on hand-held power tools, in particular eccentric grinder and hand swing grinder, consisting of a hub with support plate on the underside of which an elastic support cushion is supported on which a Velcro an abrasive sheet is fastened.
  • the support plate is designed as a bistable leaf or plate spring, so that the grinding plate is particularly suitable for processing curved surfaces can be used.
  • suction hoods are offered for such rotary grinding machines as angle grinders, which usually completely surround the grinding plate of the rotary grinding machine and which are intended to receive the grinding dust thrown outwards by the grinding wheel.
  • suction hoods are provided on the edge with a brush ring.
  • suction hoods are machine-specific and are offered only for a few rotary sanding machines.
  • the extraction hood is firmly connected to the machine housing for each machine and is system-related by a great deal larger than the sanding pad and the sanding sheet, so that during the sanding process the sanding result is not visible and pinpoint sanding is not possible.
  • the cover conceals the user's view of the edge of the grinding wheel.
  • a corresponding arrangement with a suction cup completely surrounding the suction hood is in the DE 10 2004 018 727 A1 shown.
  • the grinding wheel is usually set at an acute angle to the workpiece, which means that the disk is not always in contact with the workpiece with the entire grinding wheel surface. Accordingly, such a suction hood has a more or less large distance from the workpiece and the brush ring can not seal cleanly on the workpiece. This also leads to a poorer suction and increased dust load.
  • the grinding plate unit according to the invention has an integrated suction device in the form of a suction hood which is rotatably mounted directly on the drive shaft of the grinding plate.
  • the sanding pad has suction openings, which penetrate the sanding pad and over which the back of the sanding pad can be sucked through the sanding disk by means of the dust extraction hood. Since the suction hood is rotatably mounted on the drive shaft, there results an integrated sanding pad unit which can be used independently of the particular rotary grinding machine used.
  • the connection between the sanding pad unit and the rotary grinding machine takes place only via the drive shaft, which is screwed to a tool holder of the rotary grinding machine. Accordingly, rotary sanding machines without suction can be retrofitted with a sanding unit with integrated suction.
  • the suction hood is arranged on the rear side of the sanding pad, dust extraction through the sanding pad can take place via it.
  • the dust is therefore sucked off directly at the grinding surface and does not first have to be thrown outwards by the grinding wheel in order to be sucked off outside the grinding wheel by a projecting hood.
  • this increases the service life of the grinding wheels, as they clog less quickly.
  • the sanding pad unit is preferably designed as a retrofittable sanding pad unit which can be used universally together with any rotary sanders.
  • any rotary grinder for dust-free grinding can be equipped with a grinding disc unit according to the invention.
  • the drive shaft preferably represents the only necessary connection of the sanding pad unit with a rotary grinding machine, so that the sanding pad unit is designed to be machine-independent.
  • the only necessary connection of the sanding pad unit with the rotary grinding machine takes place at the connection flange of the rotary grinding machine, to which the sanding pad unit is screwed instead of the usually used sanding pads. Further connection possibilities between sanding pad unit and rotary grinding machine are not necessary.
  • the suction hood is preferably not part of a rotary grinding machine and / or the suction hood can not be connected directly to the rotary grinding machine.
  • the suction hood is, in contrast to the prior art, an integral part of the sanding pad unit and not part of a rotary grinding machine, so that the sanding pad unit can be used independently of the machine.
  • the rotary grinding machine can be equipped with sanding pad units of different sizes, for each of which an optimal extraction of the grinding dust is guaranteed.
  • the suction hood is preferably fastened to the drive shaft via a rotary bearing, in particular a ball bearing.
  • a rotary bearing in particular a ball bearing.
  • the suction hood needs no further attachment, especially not on the rotary grinder.
  • a sealed ball bearing is used for fastening the suction hood to the drive shaft.
  • the suction hood is designed so that the outer edge of the sanding pad remains visible during operation. This ensures precise grinding and optimal control of the grinding result.
  • the suction hood also does not hinder the user when grinding up to edges, etc.
  • the suction hood preferably has a brush ring or a sliding ring on its edge facing the sanding pad.
  • the brush ring or the sliding ring allows a rotation of the sanding plate with respect to a stationary suction hood and at the same time ensures a good seal between these two parts in order to use the generated negative pressure in the exhaust hood as completely as possible for the dust extraction through the grinding wheel.
  • the suction hood preferably has a connecting piece for a hose of a dust extraction device.
  • An industrial vacuum cleaner is usually connected to the connecting piece of the extraction hood, which sucks and absorbs the dust that forms during grinding.
  • the hose prevents the suction hood from rotating with the sanding pad due to the remaining friction in the pivot bearing.
  • the drive shaft on a rubber element. This compensates for a tilting of the sanding disk and ensures that the sanding disk always rests flat on the workpiece, if desired, and thus no sanding marks are caused.
  • the suction hood preferably has a bellows on its jacket.
  • the bellows compensates for slight differences in angle between the extraction hood and the sanding pad and ensures a good seal between these components.
  • the sanding pad is inventively provided on the front with a Velcro layer for attachment of velcro sanding wheels.
  • the Velcro layer provides a simple and mechanically secure attachment of wheeled grinding wheels and on the other hand, perforated grinding wheels can be used, in which the dust transport takes place on the back of the grinding wheels through the Velcro layers.
  • the suction openings in the sanding pad can be arranged at the optimal procedural positions and do not have to coincide with any openings in the grinding wheel.
  • the suction openings are arranged according to the invention at least in the region of the outer edge of the sanding pad. Due to the high rotational speeds of the sanding disc during sanding, dust is thrown outward due to the centrifugal force - especially in the case of dust transport in the Velcro layers - and then sucked out on the grinding wheel by the suction openings arranged there at the edge of the sanding disc. This ensures that even sanding dust, which is produced at the edge of the sanding pad, is not thrown outwards, but is safely extracted.
  • the suction openings are arranged on the edge of the sanding pad so that suction openings are always present in the radial direction on the entire circumference of the sanding pad. This ensures that dust, which moves due to the centrifugal force in the radial direction from the center of the grinding wheel outwards to the edge, always meets a suction opening at the edge of the grinding disc and is sucked through it. Seen in the radial direction, therefore, there are no gaps between suction openings through which dust could be thrown outwards without being sucked off.
  • a preferred sanding pad for a rotary grinding machine has Absaugöff openings, which penetrate the sanding pad, wherein the suction openings are arranged on the edge of the sanding pad that seen in the radial direction on the entire circumference of the sanding pad suction always exist.
  • resulting dust that enters through openings, especially perforations, in the grinding wheel in the Velcro layers behind the loop plane and then moves radially through the centrifugal forces outwards meets on this way at the edge of the sanding pad always on a suction through which the dust is sucked through the back through the sanding pad. Accordingly, dust from the grinding wheel can no longer be thrown outwards and pollute the environment.
  • the suction openings are formed as curved, mutually overlapping slots. It has been found that relatively narrow, curved, mutually overlapping slots on the edge of the sanding pad ensure optimum extraction of the sanding dust, especially with perforated grinding wheels.
  • the edge of the grinding plate is rounded at the front.
  • the sanding disc mounted on the sanding pad exerts a lower pressure during sanding than at the edge.
  • This is advantageous insofar as the edge of the grinding wheel leaves no grinding marks, which results in a better grinding result overall, in particular during fine and polishing grinding results.
  • a rounded edge of the sanding plate also edging be ground with a rounded throat.
  • the sanding pad unit according to the invention is able, since it - in contrast to an eccentric grinder - does not use an eccentric stroke but a pure rotational movement. Thus, can be ground into edges with the edge of the sanding plate.
  • the edge of the sanding plate is widened to form a lateral surface. This also allows a qualitatively optimal and fast grinding of an edge or groove of a workpiece, wherein a precise radius of the groove can be formed. Again, this is not possible with eccentric grinders.
  • the lateral surface of the sanding plate is broken with suction.
  • the dust that forms during grinding on the lateral surface of the sanding pad can be sucked through the grinding wheel through.
  • Another aspect of the present invention relates to the use of a sanding pad assembly according to any of claims 1-10 with perforated, grindable grinding wheels.
  • the abovementioned advantages of the sanding pad unit according to the invention are provided, in particular, when used together with perforated, slidable grinding wheels, in which dust which forms during grinding is removed by the shortest route through perforation openings in the grinding wheel from the grinding surface to the back into the Velcro layers, and there the suction holes in the sanding pad is sucked and then sucked through the sanding pad through.
  • perforated grinding wheels can be advantageously used now also with rotary grinding machines, which have a significantly higher removal rate compared to oscillating grinding machines.
  • FIGS. 1 to 5 show a non-inventive embodiment of a sanding pad unit 1 for a rotary grinding machine 100.
  • the sanding pad unit 1 comprises a drive shaft 20, to which by means of a screw 50, a sanding pad 10 rigid connected is.
  • a suction hood 30 is rotatably mounted on the drive shaft 20 via a ball bearing 40, via which dust can be sucked through the sanding pad 10 by means of a suction hose 120, which is fastened to an intake pipe 34.
  • the suction hood 30 is rotatably mounted only on the drive shaft 20.
  • a ball bearing 40 is inserted into a cylindrical receptacle 36 of the suction hood 30, which is held in the receptacle 36 by means of a shaft securing ring 70.
  • the bearing 40 is adapted to the outer diameter of the shaft 20 and is in contact with a stop ring 22.
  • the bearing 40 is held on the drive shaft 20 by means of a further shaft locking ring 60, which rests in a groove on the outside in the drive shaft 20.
  • a sealed ball bearing is used for the ball bearing 40 in order to maintain the highest possible negative pressure within the suction hood 30 during operation.
  • the drive shaft 20 has at its upper end a bore 24 with an internal thread, which can be fastened to a tool holder 110 of a rotary grinding machine 100 by screwing.
  • the sanding pad unit 1 can be connected to a rotary grinding machine 100, which need not have any special design features for a suction. Therefore, the sanding pad unit 1 is suitable for retrofitting ordinary rotary grinding machines 100 without suction, so that dust-free grinding can be performed even with such machines.
  • the only necessary connection of the grinding part unit 1 with the rotary grinding machine 100 is produced via the drive shaft 20, so that the grinding plate unit 1 can be used independently of the machine with any rotary grinders 100.
  • the sanding pad unit 1 is connected via the suction nozzle 34 with a suction hose 120, which is connected to a conventional industrial vacuum cleaner (not shown).
  • the connection to the sanding pad unit 1 to the suction hose 120 prevents rotation of the suction hood 30 in the grinding operation. Since the suction hood is preferably mounted rotatably on the drive shaft 20 by means of a ball bearing 40, this requires only a small holding force, which can be applied very easily by the suction hose 120.
  • the extraction via an industrial vacuum cleaner and via the suction hose 120 takes place independently and in addition to the drive by a rotary grinder 100.
  • the present invention is not limited to hand-held rotary grinders, such as the angle grinder of Fig. 8 limited.
  • the sanding pad unit 1 can also be used in industrial grinding machines or grinding machines in which rotating sanding discs are used for the serial machining of workpieces.
  • the advantages according to the invention of a lower dust load of the environment, a significantly longer service life of the grinding wheels and a better surface quality result.
  • a brush ring 32 is attached to the suction hood 30 between the fixed suction hood 30 and the rotating in operation sanding pad 10 in the first embodiment, which seals the necessary gap between suction hood 30 and sanding pad 10.
  • Fig. 2 shows that the outer diameter D of the shell 39 of the suction hood 30 substantially corresponds to the outer diameter of the sanding pad 10.
  • the sanding pad 10 preferably consists of a thin plate, for example a 2-4 mm thick aluminum plate, are introduced into the suction openings 16.
  • the grinding dust produced at the grinding surface passes through the suction openings 16 in the sanding pad 10 and is sucked by the negative pressure within the suction hood 30 via the suction nozzle 34 from the suction devices (hose 120 and industrial vacuum cleaner).
  • Velcro layer 13 which is for example a Velcro hook layer or a Velcro mushroom layer
  • velcro sanding wheels 130 can be attached.
  • Such velcro-type grinding wheels consist of a paper, fabric or film carrier on which a Velcro adhesive layer, in particular a Velcro fleece layer or a velcro velor layer, is glued on the back.
  • the abrasive wheel 130 is provided with abrasive abrasive grains which are held to the backing by a suitable potting material.
  • slidable grinding wheels 130 are provided with openings through which the grinding dust, which is formed on the grinding surface, can be sucked off.
  • grinding wheels for suction devices, namely grinding wheels with a few relatively large suction openings, which are brought into conformity with corresponding suction openings in the sanding pad 10.
  • grinding wheels have the disadvantage that the path of the abrasive grain on the grinding surface up to the corresponding suction opening is relatively long and therefore enforce such grinding wheels relatively quickly and become unusable.
  • perforated grinding wheels 130 which have a perforation of small perforation openings 132, which are distributed substantially over the entire surface of the grinding wheel 130.
  • Exemplary grinding wheels 130 having such perforation openings 132 distributed substantially over the entire surface of the grinding wheel 130 are shown in FIGS Figures 10A-10E shown.
  • the embodiments shown there show grinding wheels 130 with a diameter of about 115 mm, wherein the perforation openings 132 of the grinding wheels 130 of FIGS. 10A-C a diameter of 1 to 2 mm, the grinding wheels of Fig. 10D a diameter of 2 to 4 mm and the grinding wheels of Fig. 10E have a diameter of 4 to 6 mm.

  • the pattern of the perforation openings 132, their size and their distance from each other is determined by the respective desired grinding task.
  • Such grinding wheels 130 are common in sizes of preferably 50, 115, 150, 200 mm to 500 mm in diameter.
  • Such perforated grinding wheels 130 ensure full-surface dust removal over substantially the entire surface of the grinding wheel 130.
  • the grinding dust is sucked through the prevailing vacuum through each perforation opening 132, passes through the pad and into the Velcro layers. There, the dust flows in the Velcro layer to the suction openings 16 in the sanding pad 10, through which it is sucked.
  • the dust transport therefore takes place on the back of the grinding wheel in the Velcro adaptation layer and in the Velcro hook layer.
  • a grinding plate 10 with a specific arrangement of the suction openings 16, 17 is proposed for perforated grinding wheels 130. Due to the high rotational speeds of the sanding pad 10 during operation, the dust is transported radially outwards due to the centrifugal force. In order to ensure a dust-free grinding as possible, therefore, the suction openings 16, 17 should be located near the edge 18 of the sanding pad 10 so that dust is formed there can be safely sucked against the centrifugal force. Dust that arises in the inner region of the grinding wheel 130, inevitably migrates outward towards the edge 18 and is then also sucked there. Preferred patterns for suction openings 16, 17 are in the FIGS. 6 and 7A to 7C shown.

  • the shape and arrangement of the overlapping suction openings 16, 17 can be varied depending on the size of the sanding pad or embodiment. It is important, however, that seen from the inside to the outside there are no gaps between the suction openings through which the dust could escape to the outside. At a minimum, the gaps should not be so great that the centrifugal forces acting on the dust are greater than the forces due to the suction effect.
  • the dust resulting from the grinding passes through the perforation openings 132 through the base of the grinding wheel 130 and into the Velcro layers behind the loop plane due to the suction effect, is then transported radially outwards by the suction air and the centrifugal force and then through one of the suction openings 16, 17 , which are located at least on the edge 18 of the sanding pad 10, sucked into the suction hood 30 inside. From there, the dust is extracted from the suction nozzle 34 and the suction hose 120 in a suction device (for example, an industrial vacuum cleaner).
