Definitions

  • the invention relates to a tool for material removal Machining a workpiece according to the generic term of Claim 1, which is preferably for clamping in a hand-held machine tool is provided.
  • the object of the invention is a tool to provide generic type, which in particular when using hand-held or hand-held Machine tools reduces the aforementioned disadvantages, a more efficient material removal processing at a essentially always uniform surface quality of the Workpiece and versatile for processing different areas can be used.
  • the tool body can the tool according to the invention by simple adjustment the dimensions of the tool body for machining flat, cylindrical, curved and / or curved surfaces can be used in a user-specific manner.
  • Tool is provided, preferably an outer ring with a spoke and / or disc-shaped Connection device on a hub to hold such that cantilevered in the axial direction of the rim areas of the ring are.
  • the connector provides the retention of predetermined ring diameter, so that one on the Tool transmitted torque, similar to a wheel or Tire, essentially evenly on the wreath is passed on.
  • an area of an edge area a forced radial deformation, this affects due of the circumferential rim also on adjacent edge areas from, the opposite in the axial direction Border region deformed in the opposite direction the wreath around the Connection device tilted and as an investment area in the essentially the entire width of the wreath is guaranteed.
  • connection device in the axial direction self-resetting deformable the tool can absorb additional shear and torsional forces. Because of so in the axial as well as in the radial direction self-resettable slidable or deformable Tool, the tool can absorb slight upsets or to areas of the tool outside the contact area pass on.
  • Embodiment of the tool according to the invention have in particular in one piece from a plastic material preferably produced in an injection molding process Tool body proven to be useful and advantageous.
  • the invention in another aspect, relates a tool body, also called carrier, for receiving Coated abrasives, especially in ring or Sleeve shape, characterized in that the body from a soft plastic or elastomer is made and that in this body at least on one face Steel edge is attached or incorporated, which at the same time as wear protection for the wearer and as Side guide for the abrasive.
  • the tool body is characterized in that that on the second face by a loosely inserted Steel disc also a wear protection for the Tool body and a side guide for the Abrasive is generated.
  • An embodiment of the Tool body in which the abrasive after use can be changed easily by moving it axially.
  • the tool body expediently has a built-in Steel edge still a flexibility which the Nestling of the abrasive to the surface to be processed allowed.
  • FIGS. 1, 2 and 3 which, for example, is a one-piece injection molding process trained embodiment of the tool according to the invention represent.
  • FIGS. 1, 2 and 3 which, for example, is a one-piece injection molding process trained embodiment of the tool according to the invention represent.
  • the tool according to the invention has a cylindrical one Wreath 1, the outer surface of which is the receiving surface for attachable material-removing means 10, such as for example an abrasive sheet or paper.
  • This schematically illustrated hub can be more preferred Way over a quick coupling according to the German Utility model DE G 94 16 005.8 have, whose Content by reference also completely to the subject of Disclosure of this description is made.
  • the tool according to the invention also has a trap corresponding coupling, the concentric to the axis of rotation is arranged essentially in the center of gravity of the tool.
  • the outer surface 5 of the ring 1 has circumferential grooves 6 provided that the rotation of the tool an improved Adhesion and self-centering around the outer surface 5 ensure tensioned machining flow.
  • the disc 2 is, as can be seen particularly in FIG. 3, in the middle of the otherwise arranged hollow cylindrical ring 1, so that in axial direction the peripheral edge regions 1a and 1b of the Wreath 1 are self-supporting and in the radial direction, are flexible.
  • the radial rigidity is relatively high having disc 2 is to their flexibility in the axial Increase direction with circular around hub 3 arranged through openings 7 provided.
  • edge areas 1a, 1b and the disc 2 are the thickness dimensions of the used material, the intended use, the diameter and the width 8 of the tool depending and predefined producible.
  • the drive shaft 4 becomes sketchy, as in FIG. 3 indicated from the tool axis X, for example by a slight tilting of the machine tool in the direction of the Swiveled arrow C, change on the tool transferred forces and cause a deformation of the Tool, in particular an inclination thereof Lateral surface.
  • edge region 1 a lying on the workpiece surface 9 is deformed in the direction of arrow V1.
  • the edge area 1a in the axial Direction opposite area 1b according to the amount approximately equal deformation V2, but in opposite direction to that of the edge region 1a experiences, creating a substantially uniform Material removal on the workpiece surface 9 guaranteed is.
  • a one-sided forced deformation V1 and this forced opposite deformation of the edge regions 1a and 1b in the direction of V1 and V2 thus causes area-wise tilting of the wreath in a plane around the Disk axis Y and ensures that the Investment area continues essentially over the entire width 8 of the wreath 1 extends.
  • the disc 2 can be designed like a membrane and have a radial waveform around a to provide increased elasticity.
  • the torque can be reduced to that Tool-transmitting drive shaft 4 one-sided or also - with one extending through the tool Shaft 4 - clamped on both sides in a machine tool be, which is suitable for use of the invention Tools a diverse range of both hand-held or guided as well as automated or fixed installed machine tools.
  • the Shell surface 5, as shown in Figure 4 on the outside a cylinder 11 made of elastic solid material, such as for example, rubber, caoutchouc, an elastic polymer or the like.
  • the cylinder 11 can defined deformation or to achieve defined Restoring forces further elements inside include.
  • Belt 12 is embedded near the outer surface 3.
  • the belt 12 can be made of steel, plastic, a nylon or fabric Kevlar exist and should preferably be elastic be designed to deform the lateral surface 5 continue to allow.
  • a particularly preferred one Embodiment includes a steel belt 12 which is shown in FIG a rubber cylinder 11 is vulcanized.
  • a side guide plate 13 the has a plate-like cross section and a lateral one Stop in the axial direction for a band 14 on which the material-removing means 10 are arranged, forms.
  • This Guide disc 13 can be attached to the tool the drive shaft 4 in a single fastening step with the quick coupling mentioned above become.
  • a flat can be used to reinforce the stop shoulder 15 Ring 16 can be attached to or within the cylinder 11, which is also kept elastic in the radial direction is, however, higher lateral forces in the axial direction can record.
