Definitions

  • the present invention relates to a grinding tool according to Preamble of claim 1.
  • Rotary grinding tool known in which the Abrasive in the form of an abrasive surface having abrasive cloths with on textile or cellulose Radial material or carrier material built on plastic protruding from a driven cylindrical body are arranged. The rotating tool is now about to machined surface, with the free ends of the Abrasives hit the surface one after the other and pulled over it.
  • the tool can either be used in an automatic machine or for manual processing be used.
  • This known construction is particularly suitable in shape of small tool diameters for machining hard ones Workpieces, for example made of metal.
  • From US-A-3 869 833 is a grinding tool with a drive shaft known, which is radial to the drive axis to the outside Has abrasive, which is arranged on a carrier tape are. Each abrasive is spaced from one another aligned parallel to the drive axis from the drive axis arranged handrail attached, the handrails spaced from each other on a circular path around the Drive axis are arranged in a basic clamping body.
  • the object of the present invention was now to Find grinding tool, which workpieces also made of soft Material, such as wood, and with an arched
  • this object is achieved by a grinding tool solved with the features of claim 1.
  • the grinding tool Due to the inventive design of the grinding tool is also with large dimensions of the tool, resp. with a large machining width, also curved contours created the following abrasive, which in particular also very well used for machining soft workpieces can be, such as wood.
  • the tool can be built relatively wide, i.e. have a wide working area, and thus even large workpieces with a curved surface in just a few steps to edit.
  • the surfaces of three-dimensional curved bodies optimally and quickly processed, even with soft material of the workpiece such as Wood.
  • the tool according to the invention also has a long service life and is relatively easy to maintain respectively. to chat.
  • the tool according to the invention is particularly suitable also for machining soft workpieces but also for workpieces with a hard surface and / or straight Use surface advantageously.
  • FIG 1 is a schematic view of an inventive Shown grinding tool.
  • the grinding tool points a cylindrical base clamping body 1 with drive shaft 2 leaf-shaped protruding on and on it Abrasives 3. Between the abrasives 3 are each Spacer elements 4 arranged, the abrasive 3 from each other distance and keep in shape.
  • the grinding tool is now driven by a motor Drive axis 2 set in rotation and then tangential introduced a workpiece to be machined.
  • you can the grinding tool can be set up stationary and that too machining workpiece, for example by means of a gripper arm, which can be numerically controlled, tangential to that rotating grinding tool can be introduced.
  • FIG. 2 is now a partial view of one of the leaf-shaped Abrasive 3 shown.
  • the abrasive 3 has here, for example, an essentially rectangular shape on and is essentially in the radial direction with respect to the drive axis 2 of the grinding tool extending slots 5.6.
  • the slots 5.6 have, for example a rectangular shape.
  • the against the free Slots 5 arranged at the end of the abrasive 3 are sufficient preferably up to the free edge of the abrasive 3, i.e. it are slits open to the outside.
  • This configuration of the abrasive 3 is on the one hand created a coherent abrasive 3, the free Edge through the slots 5, respectively. 6 in practical from each other independently deflectable flags is divided and thus one flexible grinding edge, which also forms strongly shaped three-dimensional contours of workpieces to be machined can follow.
  • the abrasives 3 are in operation when they hit the Workpiece to be machined against the direction of drive rotation deflected resp. pushed away. It has now been shown that through the arrangement of the slots 5,6 according to the invention the individual edge sections of each abrasive 3 advantageously nestle together and practically a homogeneous Form grinding plane. To be strong even when editing deformed workpieces to achieve homogeneous machining, the abrasives 3 are preferably one after the other arranged in the basic clamping body 1 that in successive Abrasives 3, the slots 5, respectively. 6 not immediately are arranged one behind the other, but laterally around aligned at least the width of the slots or larger are.
  • the abrasives 3 have a conventional structure from one leaf-shaped carrier material on one side or is provided on both sides with an abrasive grinding element, such as for example sand or corunt grains.
  • the carrier material can consist of cellulosic or artificial material.
  • the abrasives 3 are via holding rods 7 with the grinding tool resp. the basic clamping body 1 of Connected grinding tool.
  • Figure 3 is the partial view shown on a part of the base clamping body 1, namely the holding disc 8 for the holding rods 7.
  • the preferably cylindrical support rods 7 are individually around their longitudinal axes are rotatably mounted in bores of the holding disc 8.
  • a holding disc 8 is shown with a few holding rods 7, the opposite holding disc 8 'is only dashed indicated.
  • FIG 4 is the longitudinal section through the outer area of the base clamping body 1 with both holding washers 8 resp. 8 'and inserted holding rod 7 shown.
  • the support rods 7 are each on the outside the retaining washers 8 and 8 'attached rings 9 against kept axial displacement.
  • the rings 9 are, for example via a clamping connection 10, for example continuous clamping screws, braced against each other and can so that the washers 8 and 8 'connect with each other.
  • the handrails 7 for weight and strength reasons should be made narrow, it is preferably provided between the two washers 8 and 8 'if necessary, more Insert support plates 11.
  • This support discs 11 have instead of bores, as the retaining disks 8, 8 'have, semicircular or U-shaped radially open to the outside Slots through which the support rods 7 radially from the outside can be introduced.
  • This tether 12 thus serves first Line as a safety device and can be by means of clamping devices clamped against the drive axis 2 of the grinding tool 1 become.
  • the corner areas of the abrasive 3 can also be rounded be formed, as shown in Figure 5 in an alternative embodiment is shown.
  • the slots 5 can also for example rounded corners, lenticular shape or one slightly curved resp. have a curved longitudinal line.
  • FIG. 6 shows the section through an abrasive 3, which is attached to a support rod 7.
  • abrasive 3 For example can in the lower area of the abrasive 3 Eye 3 'be formed, which is pushed over the support rod 7 can be.
  • the abrasive 3 on the holding rods 7 is conceivable, such as. by passing through holding slots in the Handrails 7.
  • the spacer elements 4 are preferably in the same width as the abrasive 3 formed with less Height.
  • the spacer elements 4 can for example directly connected to the corresponding sides of the abrasive 3 be, for example, glued to it, or be connected to each other, the connecting element, for example a clamp or rivet, by a corresponding one Opening in the abrasive 3 is passed.
  • the spacer elements 4 only in the foot area of the Abrasive 3 with this resp. connected and are exposed radially to the outside on the surface of the abrasive 3 on.
  • the grinding tool according to the invention is particularly suitable for processing large three-dimensional shapes Workpieces in one step.
  • the configuration of the grinding tool can be advantageous be carried out in large dimensions, preferably with a diameter of more than 500 mm, which is the machining of such workpieces in a single operation. Due to the inventive design of the Abrasive 3 with the slots 5,6 is despite the large dimensions a flexible processing zone over the entire Width of the tool achieved what the machining of soft materials such as wood in particular.
