Definitions

  • the present invention relates to an angle grinder dust hood with a hood body for covering a circular grinding wheel and with a sealing element extending along a circumference of the hood body for at least partially sealing the hood body with respect to a surface to be machined by the grinding wheel.
  • the angle grinder dust hood has a suction connection, via which a surface removal can be sucked out of the hood body.
  • the sealing element may be, for example, a brush curtain, slats or the like.
  • the sealing element is a single single elastic element or several individual elastic elements.
  • the elastic member may be a foam, an elastomer (e.g., rubber, rubber, etc.) or the like.
  • Angle grinder dust hoods of the type mentioned are basically known from the prior art. They are used to prevent dust spreading during grinding work to protect the health of a user of the angle grinder. It is known to provide the hood body with a sealing element, for example a circumferential brush curtain or with a plurality of brushes, so that the hood body terminates on the surface to be machined of a workpiece. If the angle grinder is placed slightly obliquely on the surface of the workpiece to be machined, then the sealing element can compensate a gap which may arise between the hood body and the surface of the workpiece to be machined.
  • a sealing element for example a circumferential brush curtain or with a plurality of brushes
  • a grinding tool comprises a handle assembly having a support member and a head assembly including a grinding member that is rotatable relative to the handle assembly about a drive axis.
  • the grinding tool also includes a pivot assembly that pivotally couples the head assembly to the support member of the handle assembly.
  • the support member pivotally supports the pivot assembly, the drive axle extends through the pivot assembly, and the head assembly is pivotable about a plurality of different axes relative to the support member.
  • a tool holding head for a hand-held cleaning / grinding machine comprising a plate device which is fixed or fixable on the cleaning / grinding machine, and a tool receiving device to which a tool for surface processing is fixed or fixable and which relative to the plate means about an axis of rotation is rotatable, wherein on the plate means a bearing device is elastically mounted on a processing surface, wherein the abutment means surrounds the tool receiving device.
  • an angle grinder dust hood with a hood body for covering a circular grinding wheel and with a sealing element extending along a circumference of the hood body for at least partially sealing the hood body with respect to a surface to be machined by means of the grinding wheel, and with a suction connection via a surface removal the hood body can be sucked off
  • the sealing element in the hood body in the axial direction based on the axis of rotation of the grinding wheel, is spring-mounted by at least one spring element
  • the spring element has a base bar via which the spring element is attached to the hood body, achieved in that the Spring element has at least one retaining bracket, which is adapted to prevent an axial falling out of the sealing member from the hood body, wherein the headband protrudes in the axial direction of the base web and at its other end an axial stop for a retaining rail of the sealing element is formed.
  • the spring element has a base web.
  • the spring element is attached to the hood body.
  • the invention includes the recognition that, in particular in an overhead operation of an angle grinder, a hood body with according to the prior art rigidly attached thereto brush curtain is pulled by gravity and a possibly connected to the suction suction hose down.
  • a gap between the brush curtain and the surface to be processed arise.
  • feathered in hood body brush curtain of the brush curtain is always pressed to the machined surface, whereby a gap is avoided or at least substantially reduced.
  • the invention also includes the recognition that a worn brush curtain may typically have a high stiffness with respect to the axial direction, so that a lot of force has to be expended to expose the grinding wheel against the stiffness of the worn brush curtain on the surface to be machined To bring workpiece. This is because with angle grinder dust hoods of the prior art, as already mentioned, the brush curtain is rigidly attached to the hood body.
  • the present invention includes the knowledge that an already heavily worn pad, in particular a diamond pot, is used in conjunction with a new angle grinder dust hood and the user disadvantageously against the relatively high stiffness of the still stiff brush curtain the new angle grinder dust hood already flattened sanding pad must press on the surface to be machined of the workpiece.
  • a worn pad often has a lower height, i. a less concave shape than a new or unused sanding pad.
  • the spring element takes over the axial movement of the sealing element with respect to the hood body. Any radial displacements can continue to be compensated by the sealing element itself.
  • a spring element is a preferably discrete spring element and not merely a possible spring action or resilience of the brush curtain in the axial direction.
  • the invention includes the recognition that angle grinder dust hoods of the prior art to achieve the spring action of the invention can not be developed such that a spring element is provided approximately between hood body and angle grinder housing. This would have in overhead work the disadvantage that the weight of a suction hose connected to the suction would compress such a spring in an undesirable manner.
  • the hood body is designed to cover a major part of the grinding wheel.
  • the angle grinder dust hood can have a hood segment which can be displaced in the circumferential direction of the hood body along the hood body and which is provided for, as required, gradually covering and leaving free a remaining part of the grinding wheel. This allows a near-wall grinding operation by means of the remaining part of the grinding wheel, which is not covered by the hood body.
  • a sealing element in the axial Direction based on the axis of rotation of the grinding wheel, spring-loaded by at least one spring element.
  • the spring element has a preferably flat base web.
  • the spring element may be attached to the hood body and / or the hood segment.
  • fastening takes place by means of a pin, a screw and / or a rivet.
  • the spring element is mounted directly in the hood body by means of a spring clip via an undercut.
  • the spring clip can also be referred to as a clip, so that the spring element is clipped into the hood body.
  • the spring element can also be injected directly into the hood body or into the hood housing.
  • the base web preferably at least one hole is provided, into which a pin, a screw or a rivet can engage.
  • the spring element is attached to the first and / or second retaining rail for the sealing element.
  • the spring element or the spring elements are arranged within a volume defined by the hood body or hood segment.
  • the hood body and / or the hood segment has a housing section whose curvature corresponds to the curvature of the grinding wheel.
  • the spring element is arranged in the immediate vicinity of this section.
  • the spring element is arranged as far as possible from a rotation axis of the grinding wheel within the hood body volume or the hood segment volume.
  • the spring element has at least one spring rocker protruding from the base web.
  • the spring element is mounted such that the orientation of the projecting spring wings preferably corresponds approximately to the outer periphery of the hood body.
  • the spring element is also arranged radially.
  • the spring element has two spring wings projecting from the base web. In this way, a higher stability of the spring element in an assembled state and an increased spring force can be achieved.
  • the spring wings When the spring element is mounted, the spring wings form a tangent to the circular grinding wheel or to the oval body of the grinding hood.
  • the headband in the radial direction based on the axis of rotation of the grinding wheel, for the purpose of replacing the brush curtain deflected.
  • the axial stop may be formed as a stop web, which preferably extends parallel to the base web.
  • the stop formed as an axial stop has a recess, so that a contact surface between the stop web and the running as a brush curtain sealing element or the holding rail of the brush curtain is reduced.
