Definitions

  • the invention relates to a front part that can be used in particular for grinding and polishing work in machine tools, with a drive pulley that has a Velcro layer on one side and a flexible shaft that can be converted to a rigid barrel on the other side, and a working disk that has a machining disk on the workpiece side and on the drive side is provided with a fabric that can be connected to the Velcro layer of the drive pulley to form a Velcro fastener.
  • Front parts with drive pulleys, which are Drills are set in fast rotating motion and carry a work disc on the workpiece side are known.
  • the axis of the front parts is made using a flexible shaft keep flexible or not.
  • attachment parts are designed in such a way that they have a foam layer on the underside of the drive disks in addition to the flexible shaft, which improves the grinding performance.
  • these attachments are not suitable for work that is carried out with a rigid shaft and a high number of revolutions, while optimal results cannot be achieved with attachments without a foam layer during grinding and polishing work.
  • the invention has for its object to design a front part of the type mentioned above so that it can be used for all grinding and polishing work and can be quickly and easily converted to the respective area of application.
  • the working disc is constructed in two parts in the front part and consists of a fabric-backed processing disc and a foam disc, the disc surfaces of which are each provided with a Velcro and a fabric layer.
  • a secure and easily detachable connection between the drive disk, foam layer and processing disk is in each case made by means of a Velcro fastener.
  • the attachment can be used for work that does not require an intermediate foam layer easy to remove this layer convert, whereby the known shape of the front part with drive pulley and connected work disc is produced.
  • the worktop is designed as a polishing cloth or polishing fleece.
  • working wheels are provided in which the abrasive grains are bonded with synthetic resin. With these grinding wheels, considerably longer service lives can be achieved than with prior art wheels, in which the abrasive grain is applied to a paper carrier glued to the base.
  • the Velcro layer is integrally formed on the drive pulley. This prevents the connection adhesive between the hook-and-loop layer and the drive disk from becoming detached, as in the case of a drive disk according to the prior art, by heating under high loads.
  • a shaft in which at least one section is flexible and which has a stop at the drive end of the flexible section, can be connected to a receiving part of the drive pulley in such a way that its flexible section lies outside the receiving part.
  • the flexible part of the shaft can be fixed by an attached sleeve that can be clamped between the receiving part and the stop.
  • the front part shown in FIG. 1 has a drive disk 1 with a shaft 2 and a working disk 3 which is adhesively connected to the drive disk 1.
  • a Velcro layer 4 is integrally formed on the underside of the drive pulley 1, the elements of which can be hook-shaped, mushroom-shaped or T-shaped.
  • the working disc 3 With the Velcro layer 4, the working disc 3 is bonded to a Velcro fastener via a fabric layer 5, which can be made of velor, for example. bound.
  • the embodiment of the front part shown in the figures is suitable for grinding work.
  • the working disk 3 is constructed in two parts and has a processing disk 6 and a foam disk 7. The connection between the processing disc 6 and the foam disc 7 is again made by a Velcro closure.
  • the processing disk 6 is to ewebe für with a G deposited 8, while, on the side facing the machining wheel disc face a Velcro layer 15 is applied to the foam disc 7, which consists of high pressure PU-foam or similar materials.
  • the layers 5 and 15 on the disc surfaces of the foam pad may be glued, as lanschleifen or on the P polishing required, relatively low speeds, the strength of the adhesive by heating is not impaired.
  • the fabric layer 8 is connected to the synthetic resin bed without adhesive.
  • the drive pulley 1 On the drive side, the drive pulley 1 has a receiving part 9, into which the shaft 2 is screwed with an end having a screw thread 10. Between screw thread 10 and a stop 11, the cross-sectional area of which is designed to facilitate the assembly of the shaft 2 as a hexagon, the shaft 2 has a flexible section 12. The stop 11 merges into a shaft part 13 on the drive side, which can be used, for example, in a drill chuck is.
  • the flexible section 12 lies outside the receiving part 9.
  • the flexible section 12 can be fixed for a rigid running of the shaft by means of a cylinder sleeve 14 which holds the flexible section 12 overlaps and is clamped between the receiving part 9 and the stop 11.
  • the position of the cylinder sleeve 14 is indicated by dashed lines in Figure 1. If necessary, the cylinder sleeve 14 can be removed by unscrewing the shaft 2.
  • the front part enables exact grinding on flat surfaces.
  • the processing disc 6 of the front part can be placed directly in front of the working disc 1 when the foam disc 7 is removed, the two discs adhering to one another by means of a Velcro fastener. Due to the flexible shaft, precise grinding is possible.
  • the processing disc 6 can also consist of a polishing cloth or polishing fleece, so that all the polishing work can be carried out with the front part.
