Definitions

  • Support plate for rotating tools for example as a tool attachment for hand drills, have long been in one piece from an elastomeric material known, with a front adhesive surface, for example, smooth for Glue a grinding or polishing disc with an adhesive back or with a full or partial hook surface ("Velcro") for easy Adhesion of grinding or polishing discs with a suitable back Loop covering is provided.
  • a front adhesive surface for example, smooth for Glue
  • a grinding or polishing disc with an adhesive back or with a full or partial hook surface (“Velcro") for easy Adhesion of grinding or polishing discs with a suitable back Loop covering is provided.
  • the grinding or polishing wheel When working with such a backing pad the grinding or polishing wheel is usually not fully opposed the workpiece pressed on, but angled, depending on the pressure and resilience of the backing plate material a smaller or larger contact area arises.
  • the grinding and polishing discs wear out quickly and are therefore easy to replace.
  • the support plates also experience Wear and damage from careless work,
  • the object of the invention is to provide a support plate that is as uncritical as possible is to be handled and which can be used at different costs Adapts work requirements and in the event of damage in the area of Can cheaply renew adhesive surface.
  • a support plate according to claim 1.
  • Such a Backing pad allows the use of conventional inexpensive grinding, Polishing or the like.
  • Working medium discs on an adhesive surface which on an elastic deformable plate lies and thus without the risk of dangerous Edge lies flat against the workpiece to be machined.
  • this plate can not only be replaced when worn or Damage is present, but also if a softer or firmer pressure is required.
  • Such a removable plate can also be replaced if, for example, a smooth adhesive surface instead of a hook is desired for other working medium discs.
  • a quick-change connection in the manner of a bayonet intervention in particular if possible at a fixed direction of rotation of the rotating tool easy release in the opposite direction. It is understood that quick change connections for this purpose also in another known manner without further notice, for example in the form of "clip" or snap connections.
  • the one behind it normally on the drive side not replaced mounting bracket with a coupling extension in engages the interior of the interchangeable plate, so that it admittedly towards the outside includes the plate material to be specified for the supporting forces, but on the inside is reduced from the material and thus also from the material costs.
  • the interior can the removable plate are firmly supported on the mounting bracket.
  • the removable plate can be broken into a ring shape be or only as a closed adhesive surface on the front thin cover surface are formed.
  • the receiving carrier can advantageously be around the area of the inside Quick change connection around still have a flange with which it supports the removable plate over a ring area, so that the removable plate can accordingly be made thinner and thus material-saving.
  • the removable plate can also be used as a tool in many cases be trained if the material-saving and flexible design of the Removable plate offers a brush-like design.
  • Support plate comprises a receiving carrier 2 and an annular interchangeable plate 3.
  • the receiving carrier 2 consists of one with respect to a central axis 4 essentially axially symmetrical plastic injection molded part with an embedded metal nut 5 that fits on a Unscrew the threaded stub of a drive machine and thus one Forms drive connection.
  • Around this drive connection 5 has the Recording carrier 2 a grip circumference 6 with six ribs 7 for a better Hand or tool attack.
  • the Recording carrier 2 On the front axially opposite the drive connection 5 is the Recording carrier 2 with a coupling extension 8 to a quick change connection equipped with the removable plate 3.
  • the coupling extension is on the radial inside 8 broken through to mother 5, so that there is a free one Access for lock nuts, locking elements and the like.
  • To one Ring collar 9 around the inside of the nut 5, which is to the front of the Support plates protruding from the mother as a protective ring are two blind holes 10,11, arranged radially opposite each other to provide access for one Allow wrenches from the front.
  • the receiving support 2 provides a spiral, slightly undercut edge contour of the coupling extension 8 a snail receptacle that works in conjunction with a suitable Counter contour is very easy to bring into rotation specified direction of rotation at work itself, in the opposite direction but is also easy to solve.
  • the receiving carrier 2 goes along the interchangeable plate 3 a rigid, positive connection.
  • the smooth undercut shape with a sloping flank is easier and faster to do handle as a stepped edge contour.
  • the receiving carrier 2 supports the removable plate 3 with a Flange 13 over part of the (larger) radius of the removable plate 3 from, so that these are relative given the deformability and flexibility can be thin and therefore inexpensive.
  • the interchangeable plate 3 rests with a rear annular surface 14 on a suitable annular surface 15 of the flange 13. In the present case, both ring surfaces are flat, although this is not absolutely necessary as long as there is only a suitable adaptation. In an annular region 16 that extends beyond the flange 13 of the receiving carrier 2, the thickness of the exchangeable plate 3 decreases towards an outer edge 17. It is of particular interest that the interchangeable plate 3 is not planar in an edge region of the front side 18, but is raised or spherical, so that a slightly oblique placement of the support plate is already partially taken into account. The interchangeable plate 3 and thus also its front side 18 have a recess on the inside, the spiral edge 19 of which cooperates with the coupling extension 8 of the receiving carrier 2.
  • the opening in the front side 18 is harmless insofar as only the peripheral regions of the exchangeable plate are required for the work intervention. Otherwise, the middle area could also be closed off on the front side 18 by a possibly thin-walled inner area. However, the quick-change connection to the receiving carrier 2 would then be covered and thus more difficult to control.
  • a working medium disc - for example a grinding disc - is to be attached with an adhesive back and removed when it is used.
  • the interchangeable plate 3 can depend on the plate thickness and the course of the plate thickness towards the edge, from the choice of material, from the outside diameter and / or from the frusto-conical or convex shape of the front 18 can be varied the different work equipment and the different deformations to offer appropriate panel properties when working. There are different To provide removable disks without this being the case with a inventive material-saving design and a simple Exchange option would be expensive. Removable disks can also be used to be present in exchange, in which the surface is not only as with present embodiment, smooth and thus as an adhesive surface for self-adhesive Suitable work tool discs, but also with hook trimmings or with Clamping elements are provided.
  • removable disks can be exchanged against the removable disks described above, which themselves are designed as work equipment.
  • this removable plate can be used be equipped with brushes or nubs for post-processing and can be used after grinding or with abrasive filled Bristles can be provided for grinding.
  • a further interchangeable plate 23 is shown, which is opposite the 4 and 5 a smaller outer diameter but has the same spiral edge 19 on a free inner Breakthrough opening 24 for placement on a receiving support 2 according to FIG. 1 and 2.
  • the removable plate is made in one piece from an elastomeric material and in this respect, as a whole, being flexible, on the receiving support 2 put on, through this finds firm support.
  • bristle-shaped Extensions 25 each have a conical cone shape that leads to a flat boundary surface taper, this flat boundary surface defining a work surface 26.
  • Such bristle-like extensions 25 are resilient, as you would for Grinding, polishing or brushing required.
  • the flexibility in or against the direction of rotation of the interchangeable plate 23 is made by a 8 supports the cross-sectional shape of the bristle-like extensions 25, which is a larger dimension in the radial direction than in the tangential Direction.
  • the bristle-like extensions 25 are slightly radial placed inwards so that they tend to stand up when rotating than being deflected outwards.
  • the bristle-like extensions 25 are coated with an abrasive, namely powdered corundum, filled and can be used instead of Grinding wheels are used. It is understood that in the elastomer Material of the removable plate 23 other polishing materials can be embedded can or on such extensions as the pin-like extensions 25 can be applied to the surface.
  • an abrasive namely powdered corundum
