Definitions

  • the invention relates to a variable clamping device for tools, which consists of a holder to be attached to a workbench and a tool holder which can be releasably connected to it, which has a slotted clamping ring as a tool holder and a fastening projection which runs approximately perpendicular to the clamping ring axis for connection to at least one compatible fastening device the bracket.
  • Clamping devices of the type mentioned are known and are used above all in the home improvement area.
  • a known clamping device which is provided specifically for clamping a hand drill
  • the holder in a table support leg and in a back leg each has a fastening device, to which the known tool holder can optionally be fastened in two mutually perpendicular positions.
  • the tool holder or, in this case, drill holder in the fastening devices, which are designed as clamping rings can be rotated with its cylindrical extension around the cylinder axis of the insert, so that there are various possibilities for positioning.
  • a disadvantage of the known clamping device is the limited range of variation of the fastening possibilities for the tool. This is due to the fact that positions of the tool holder between the two predetermined positions and outside of these positions are not possible.
  • the device should also enable the immediate variable clamping of a tool without the tool holder being interposed.
  • a clamping device of the type mentioned at the outset in which the holder consists of a fixed part to be fixed to the table and a pivotable part which is articulated to the fixed part and can be pivoted and locked, the pivoting part having the fastening device for the tool holder.
  • This design of the device with a swivel part enables free positioning of the fastening device for the tool holder within the limits of the swivel range, so that in addition to two basic positions, as is available in the prior art, any number of further positions can be set in which the swivel part can be locked in place.
  • a pivotability of the pivot part about a horizontal pivot axis is preferably provided, since this Axis position most closely corresponds to the practical requirements placed on such a device.
  • the swivel part can be swiveled from a horizontal basic position, in which it rests on the fixed part, by at least 90 ° into a vertical position and optionally by a further 90 ° into a second horizontal position.
  • the swivel part In its basic position, the swivel part is supported on its underside and can therefore also absorb very high loads in the vertical direction.
  • the swiveling range is at least 90 ° from the basic position, a position perpendicular to the basic position being achieved.
  • the swivel range can be even larger, e.g. B. by a further 90 °. This does indeed result in a direction of the swivel part which corresponds to that of the basic position; the swivel part is no longer on the fixed part, but is pivoted away from it, so that further clamping options open up.
  • the fixed part of the holder is expediently a screw clamp with a table support leg and an approximately perpendicular vertical leg, and the pivot axis preferably runs in the corner region formed by the two legs approximately parallel to the adjacent edge of the table clamped by the screw clamp.
  • this ensures easy attachment and detachment of the device and, on the other hand, enables the pivoting part to be pivoted beyond the edge of the workbench, which is advantageous for some work.
  • the fastening device of the swivel part of the holder is for the tool holder
  • the inside diameter of the clamping ring of the tool holder is the same as the clamping ring
  • the fastening projection of the tool holder is a cylindrical pin that fits the clamping ring of the holder. This ensures that tools that can be inserted into the tool holder can also be clamped directly into the swivel part.
  • the two clamp legs are essentially plate-shaped with a vertical slot H of width H running approximately centrally in the plates over part of the plate length and passing through the corner region, in that the corner region has a recess in its central part, which hinge-like takes up a pierced extension of the pivoting part with little play, and that through the corner region of the legs and the extension a clamping screw forming the pivot axis is guided in a threaded bore in its end region facing away from the screw head.
  • a simple wrench is sufficient, as it is included in every home improvement or workshop equipment.
  • a preferred embodiment provides that, in addition to locking the swivel part, the clamping ring of the swivel part is also tensioned by means of the tensioning screw.
  • the slot of the clamping ring of the swivel part of the holder runs parallel to the slot in the fixed part of the holder through the neck and has a width h that is less than the width H of the slot in the fixed part.
  • the embodiment of the tensioning device 1 shown in this figure without a tool holder essentially consists of a fixed part 2 and a pivoting part 3 pivotally connected to it.
  • the fixed part 2 has the shape of a screw clamp with a table support leg 2l, a right-angled part thereof Vertical leg 22, a tensioning leg 23, which in turn runs at right angles thereto, and a tensioning screw 23 ⁇ guided through the latter leg 23 with an actuating handle 23 ′′.
  • the table support leg 2l lies with its underside 2l ⁇ on a work table 5, which is formed from a wooden plate 5l.
  • the vertical leg 22 lies with its inside 22 ⁇ on the front edge 52 of the table 5.
  • the pivot axis 30 consists of a screw 27 which is guided in a bore 26 'and at the same time runs through a pierced extension 33 of the pivot part 3, which results in a stable hinge.
  • the pivot part 3 consists essentially of a clamping ring 3l with a central opening 32 for receiving a suitable attachment of the tool holder.
  • the shape and function of the swivel part 3 and its interaction with the tool holder are explained in more detail with reference to the figures yet to be described.
  • a marking line 36 is attached to the swivel part 3, on which, in cooperation with an invisible degree scale attached in the corner region 20 of the fixed part 2, certain angular positions of the swivel part 3 can be read.
  • the swivel part 3 In its basic position, as indicated in dashed lines, the swivel part 3 lies with its underside 3l ⁇ flat on the table support leg 2l of the fixed part 2. From there it is pivotable about the pivot axis 30, the pivot angle is at least 90 ° and preferably even 180 °.
  • the fixed part 2 can also be fastened to the table 5 by means of screws which can be guided from above through holes 29 through the table support leg 2l.
  • Figure 2 shows the clamping device of Figure 1 in a front view, the pivoting part 3 in a vertical, ie. H. 90 ° from the basic position upward pivoted position.
  • the vertical leg 22 and the clamping screw 23 ⁇ with its actuating handle 23 ′′ can be seen here from the fixed part 2.
  • the fixed part 2 is in turn clamped to the work table 5 by means of the clamping screw 23 ⁇ , the front edge 52 of the wooden plate 5l being visible in this illustration.
  • a slot 24 runs approximately centrally in the vertical leg 22 from the corner region 20 over part of the length of the leg 22. Furthermore, in the corner region 20 there is a recess 25 in the central region thereof, which serves to receive the extension 33 of the pivot part 3.
  • An aligned bore 26, 35, 26 ⁇ , through which the screw 27 is guided, runs through the corner region 20 and the shoulder 33. At one end, the screw 27 has a head 27, which is supported by a washer 28, for receiving a wrench. At the end of the screw 27 facing away from the head, the bore 26 ⁇ has a suitable mating thread.
  • the pivot part 3 which - as already mentioned - consists essentially of the clamping ring 3l with its central opening 32, has in its lower part parallel to the slot 24 through the clamping ring 3l and Approach 33 extending slot 34.
  • This slot 34 has a relatively small width h, while the slot 24 in the vertical leg 22 of the fixed part 2 has a larger width H.
  • the pivot part 3 can be pivoted about the pivot axis 30, realized by the screw 27.
  • the diameter of the opening 32 is expanded sufficiently by the slot 34 in order to be able to use the tool holder with a corresponding extension piece.
  • the screw 27 By actuating the screw 27 in the tightening direction, the slot 34 is closed and the slot 24 is reduced in width until a tool holder inserted into the clamping ring 3l of the swivel part 3 is firmly clamped and until at the same time the swivel part 3 is moved from the outside to the two sides of the Approach 33 acting clamping force is locked in position.
  • the screw 27 thus fulfills three functions at the same time, namely that of the pivot axis 30, the locking device for the pivot part 3 and the clamping screw for the clamping ring 3l.
  • FIG. 3 which shows a top view of the device 1, it can be seen that the slot 24 also extends from the corner region 20 over part of the length of the table support leg 2l. Furthermore, the holes 29 for carrying out screws for fastening the fixed part 2 to the wooden plate 5l of the work table 5 can be seen in the table support leg 2l.
  • pivot axis 30 or the screw 27 runs parallel to the table edge 52 immediately in front of it, so that depending on the pivoting position of the pivoting part 3, this one above the table 5 and once outside the surface of the work table 5.
  • the screw head 27 ⁇ also lies outside the table top 5l, so that favorable access to the screw head 27 ⁇ and a wide actuation area for a wrench are ensured.
  • FIG. 4 shows an application example of the clamping device 1 according to the invention together with the tool holder 4 and a tool 6 held by the latter, in the exemplary embodiment a vice.
  • the fixed part 2 of the device 1 is in turn fastened to a work table 5 by means of the table support leg 2l and the clamping screw 23..
  • the clamping screw 27 forming the pivot axis 30 can also be seen in this figure.
  • the tool holder 4 is clamped with a cylindrical extension 4l in the swivel part 3 or its opening 3l.
  • the tool holder 4 has a holder body 42 and a clamping ring 43 with a clamping screw 44.
  • a graduation scale is attached directly opposite the swivel part 3, by means of which a desired angular position can be set by rotating the tool holder 4 about an axis of rotation 40, which corresponds to the central axis of the projection 41.
  • the vice 6 is clamped with a suitable cylindrical extension 6l, which in turn can be rotated about an axis of rotation 60 which corresponds to the longitudinal axis of the extension 6l.
  • the Dreh greatest. Pivot axes 30, 40 and 60 in directions perpendicular to each other, so that the tool 6, which can also be a hand drill, for example, can be moved into almost any position and locked there.
