Definitions
- the invention relates to a rotatably driven tool clamping device with at least two clamping disks and a common clamping screw for clamping a tool sleeve between the two clamping disks.
- Tool sleeve means within the scope of the invention a sleeve-like tool, that is, a sleeve with a tool-forming sleeve outside. This can be, for example, an abrasive paper sleeve, a brush sleeve with radially projecting bristles, or the like.
- the invention has for its object to provide a rotatably drivable tool clamping device of the type described above, which, without a rubber core or the like supporting body, always ensures correct positioning and stabilization of the clamped tool sleeve, so that no deformations result from the stresses applied during use , i.e. a cylindrical tool surface is always available, even if the tool sleeve is made of flexible material.
- the invention provides that the one clamping washer, the clamped tool sleeve on the outside overlapping axial webs and the other clamping washer in a corresponding distribution, for. B. 120 ° distribution, insertion recesses for the web ends of the axial webs. Thanks to these axial webs, the cylindrical shape of the tool sleeves is retained even with extremely high centrifugal forces.
- the tool sleeves can have longitudinal grooves for concealed accommodation of the axial webs, but the axial webs can run between the tool elements projecting over them on the sleeve surface.
- the axial webs preferably limit the associated annular groove on the outer circumference side, ie they do not protrude beyond the outer circumference of the tensioning discs.
- a centering cone can be attached to each of the ring grooves, which facilitate centering and positioning of the tool sleeves.
- the invention proposes that the two clamping disks are distanced when the tool sleeve is clamped over a central shaft with a longitudinal bore for the passage of the clamping screw, with one clamping disk the central shaft with a polygonal insertion recess at the end and the other clamping plate be has a corresponding mandrel.
- the polygonal insertion recess or the polygonal insertion mandrel are so matched to the circumferential distribution of the axial webs that the two clamping washers can be inserted quickly and properly with the interposition of the relevant tool sleeve without interfering manipulation and can be clamped by means of the clamping screw.
- the central shaft also ensures that the two clamping washers are always properly spaced, i.e. deformation of flexible tool sleeves is prevented during the clamping between the clamping washers.
- the axial webs and the central shaft ensure a rotationally fixed connection between the two tensioning disks, the axis of rotation always running through the tensioning disks and the central shaft or the tensioning screw.
- the invention recommends that the clamping screw has a clamping nut designed as an adapter, which can be inserted in a non-rotatable manner on the one hand into an outside insertion recess of the clamping plate in question and, on the other hand, for connecting a rotary drive, for. B. a drill or angle grinder is set up.
- This adapter which is regularly designed as a merchant, can be easily inserted, for example, into the clamping head of a drilling machine or angle grinder and also has a threaded hole into which the clamping screw is screwed in at the end. At the same time, a rotationally fixed fit of the adapter is ensured in the insertion recess of the associated clamping washer.
- a tool sleeve made of flexible material insert bushing with essentially the same width in the tool sleeve.
- Such a stabilizing bushing can also serve as an abutment for the tool elements, so that the tool elements are not pressed back into the sleeve interior as a result of the applied stresses.
- the tool sleeve is made of flexible material. It can be z.
- the figures show a rotatably drivable tool clamping device with at least two clamping disks 1, 2 and a common clamping screw 3 for clamping a tool sleeve 4 between the two clamping disks 1, 2, the axis of rotation 5 passing through the clamping disks or clamping screw 3.
- the two clamping disks 1, 2 have concentric annular grooves 6 for clamping tool sleeves 4 of substantially the same diameter, i.e. each clamping disk 1, 2 each has at least one such annular groove 6.
- One clamping disk 1 has the clamped tool sleeve on the outside overlapping axial webs 7, the other clamping disk 2 in an appropriate distribution, e.g. B. 120 ° distribution, insertion recesses 8 for the web ends of the axial webs 7.
- the axial webs 7 limit the associated annular groove 6 on the outer circumference.
- a centering cone 9 connects to the ring grooves.
- a tool sleeve 4 made of flexible material is used. According to the embodiment, it is a brush sleeve with radially projecting bristles 17, for. B. U-shaped bristles, this tool sleeve 4 is bristle-free in the region of the crosspieces 7 overlapping it.
