Definitions

  • the present invention relates to an apparatus for polishing and grinding surfaces of a workpiece.
  • Polishing or grinding deep-lying areas or contours can be difficult, especially if emery paper is used, which is more suitable for large-area surface treatment.
  • a tool would be necessary with which individual surfaces can be processed in a targeted manner, without large-area processing taking place and without additional processing of areas that do not require surface treatment. It is therefore an object of the invention to provide a device which enables selective machining of surfaces for fine machining.
  • an apparatus for polishing and grinding surfaces of a workpiece comprising: a container having an opening, an abrasive material for polishing or grinding, and a member for moving the abrasive material to the opening.
  • a device comprising: a threaded rod, a base with an internal thread, the internal thread engaging the thread of the threaded rod, and a rotary device for imparting rotary motion to the threaded rod.
  • a device is made available, wherein the abrasive material comprises steel wool, in particular stainless steel wool, or consists of steel wool, in particular stainless steel wool.
  • a device wherein the abrasive material comprises Ballistol and/or plastic.
  • a device is made available, wherein the abrasive material is comprised of a plastic.
  • an apparatus wherein the abrasive material is flint, quartz, corundum, emery, garnet, natural diamond, corundum, silicon carbide, chromium oxide, cubic boron nitride, or diamond.
  • the complementary means is a protrusion or a groove into which the protrusion engages, the groove being longitudinally directed and being arranged on the container or the base and wherein the prominence is directed longitudinally and is arranged on the base or the container.
  • an apparatus comprising: a base for transporting the abrasive material to the opening and a punch connected to the base for pushing the base to the opening.
  • An idea of the invention can be seen as providing a device that is suitable for grinding and polishing wooden surfaces, ornaments, internal edges and similar places that are difficult to access or require careful processing.
  • the device according to the invention can be used to compress and enclose the steel wool.
  • FIG. 1 shows a device according to the invention with a rectangular or square cross-section of the container 2,
  • FIG. 2 shows the same device according to the invention in a perspective view with the rotary device 4 which is firmly connected to the threaded rod 3.
  • FIG. 4 shows a cross-section of the embodiment of FIG. 3 with embossments 9 which engage in grooves of the base 6 in order to prevent the base 6 from turning as well
  • Fig. 5 shows an alternative embodiment of the invention with a stamp 7 for generating the feed for transporting the abrasive material 5 to the opening of the container 2.
  • FIG. 1 shows a device according to the invention with a base element 1 in which a rotating device 4 is arranged, by means of which a threaded bolt 3 can be rotated.
  • a block of material 5 can be displaced within a container 2 by rotating the threaded bolt 3 , in particular to the front opening of the container 2 .
  • the material block 5 consists, for example, of steel wool, high-grade steel wool, it being possible for the steel wool or high-grade steel wool to be used in any fiber thickness. the In a particular embodiment, steel wool may be in a compressed form.
  • Fig. 2 shows a perspective view of the device 8 according to the invention with the container/container 2 in which the abrasive material 5 is arranged.
  • the abrasive 5 is pressed as a block that can be moved within the container 2 to the opening, so that abrasive material 5 can always be arranged at the opening.
  • the abrasive material is pushed to the opening with a threaded rod 3 , with a base/carriage/cart 6 having an internal thread which meshes with the external thread of the threaded rod 3 .
  • the threaded rod 3 can be turned with a turning mechanism/device 4, whereby the base is shifted towards the opening of the container 2, thereby conveying the abrasive material 5 towards the opening as well.
  • the rotating mechanism/rotating device 4 is therefore firmly connected to the threaded rod 3 so that a feed is generated by the base and the abrasive material 5 can be conveyed to the opening of the container 2 . If the container 2 is rectangular or square in cross-section, there is also no risk that a suitable rectangular or square base will not mesh with the threaded rod 3, but will instead rotate and thus not fulfill its function of generating a feed for transporting the abrasive material 5 .
  • FIG. 3 shows a device according to the invention with a container 2 which has a round or circular cross-section.
  • the base 6 must be guided so that the base 6 does not rotate when the rotary device 4 rotates, as a result of which the threaded rod 3 is driven.
  • Guidance can be made possible in that the base has a prominence which engages in a groove of the container 2 directed in the longitudinal direction.
  • the base 6 can be prevented from rotating as well in that the container 5 has a protrusion on its inside which is directed in the longitudinal direction and which engages in a groove of the base 6 .
  • FIG. 4 shows a cross section of the container 2 of the embodiment of FIG.
  • FIG. 5 shows an alternative embodiment with a stamp 7 which can press the base 6 in the container 2 to open the container 2.
