Definitions

  • the invention relates to a sanding disk holder for a hand-held electric grinding tool with the generic features of claim 1.
  • An inventive Schleiftelleraufname with the features of claim 1 has the advantage over that given by the arrangement of the driving pin and the screw holes on a common circle around the central axis of the bearing flange while equidistant arrangement of each adjacent driving pin or screw holes a simple assembly of a sanding pad is because there are a lot of ways to plug it up. At the same time, there may be no incorrect assembly during assembly of the sanding plate, since the driving pins always engage in any case in a through hole of the sanding plate.
  • the entire bearing flange can be produced in a single step. This is particularly advantageous in an embodiment of the bearing flange and the driving pins made of plastic, since only a single tool for the production of the entire bearing flange is needed.
  • the driving pins each have an insertion bevel at their free ends, a very simple and safe introduction of this driving pins in through holes in the sanding plate is possible, even if there is a slight rotation of the sanding pad against its end position on the bearing flange.
  • the through holes in the grinding disc can also have the same diameter. This achieves a larger number of possible attachment positions of the sanding disk on the bearing flange, which simplifies assembly.
  • a cover the bearing which is arranged in a recess of the bearing flange, sets in the axial direction, a very simple and inexpensive to be realized possibility of axial fixation of the bearing is achieved.
  • the bearing is protected against dust. It is particularly advantageous if the cover engages positively with an engagement member in the radial direction in the recess of the bearing flange. As a result, a very good axial fixation of the bearing is achieved on the bearing flange.
  • the cover has a collar which is positively engageable with a central hole of an insert plate of a sanding plate in the radial direction, the assembly of the sanding plate on the bearing flange is further simplified.
  • FIG. 1 shows a bearing 1 in the form of a ball bearing.
  • This bearing 1 serves to connect a drive axle a hand-held electric grinding tool with a sanding pad 5 (see Figures 5 to 7).
  • FIG. 2 shows a bearing flange 2 according to the invention.
  • surface 18 On its side facing the sanding pad 5 surface 18 four protruding in the axial direction driving pin 3 are formed.
  • the surface 18 also has four bolt holes 8.
  • the driving pins 3 and the screw holes 8 are arranged on a common circle around the central axis of the bearing flange 2. The distances between each adjacent driving pin 3 and screw holes 8 are the same size. In addition, the driving pins 3 and screw holes 8 are always arranged alternately on the circle. Thus, there is always a screw hole 8 between two driving pins 3 and vice versa.
  • the driving pins 3 are formed at their free end, each with an insertion bevel 16. As a result, the sanding pad 5 can be screwed onto the bearing flange 2 more easily (see FIGS. 6 and 7).
  • the bearing flange 2 is preferably made in one piece with the driving pins 3 in plastic. As a result, it has only a very low weight and is very simple and inexpensive to manufacture. For example, it can be produced by a single injection molding process using only a single injection molding tool.
  • FIG. 4 shows a cover 4 which has an engagement part 7 and a collar 9.
  • the cover 4 is preferably made of plastic, as it is very light and can be easily and inexpensively manufactured.
  • an electrical isolation of the armature shaft (not shown) of the eccentric grinder 15 with respect to the sanding pad 5 is thereby achieved. Further details of how the cover 4 cooperates with the bearing flange 2 and the sanding pad 5 are shown in FIGS. 6 and 7 and are explained below.
  • FIG. 5 shows a sanding pad 5 which is screwed onto the bearing flange 2 (see FIGS. 6 and 7).
  • the sanding pad 5 has an insert plate 10, which is preferably made of plastic.
  • the insert plate 10 has a central hole 13 and arranged on a circle around the central axis of the insert plate 10 suction holes 14th
  • a total of eight equidistantly arranged through holes 12 are formed on a further circle about the central axis of the insert plate 10.
  • the radius of this circle corresponds exactly to the radius of the circle on which the driving pins 3 and the screw holes 8 of the bearing flange 2 are arranged.
  • the through holes 12 of the sanding pad 5 can be brought into coincidence with the driving pin 3 and the bolt holes 8 of the bearing flange 2. More about this and for mounting the sanding pad 5 on the bearing flange 2 is below with reference to Figures 6 and 7 executed.
  • the insert plate 10 is foamed in a known manner with a foam 11. Since this is not essential to the invention, will not be discussed here in detail.
  • FIG. 6 shows a preassembled eccentric sander 15 in which a sanding disk holder according to the invention (see FIG. 3) is already mounted.
  • the cover plate 4 is inserted into the bearing flange 2 of the grinding disk holder according to the invention.
  • the engagement member 7 (see Figure 4) of the cover 4 engages here in the recess 17 (see Figure 2) of the bearing flange 2 and thereby fixes the bearing 1 in the axial direction with respect to the bearing flange 2.
  • the cover 4 thus acts not only as an electrical insulation against the armature shaft, but also protects the bearing 1 against dust entry, resulting in a longer life of the bearing 1.
  • the cover 4 When mounting the sanding pad 5 on the bearing flange 2, the cover 4 serves as a centering, since it can be seen well through the central hole 13 of the sanding pad 5.
  • the sanding pad 5 must be properly arranged only in its angular position, so that the driving pins 3 engage in the through holes 12 and it can be fixed by means of screws 6.
  • the screws 6 are preferably four plastic forming screws.
  • the correct placement with respect to the angle of the sanding pad 5 on the bearing flange 2 is further simplified by the above-described insertion bevels 16 of the driving pins 3.
  • the invention is by no means limited to a total of eight through-holes 12 in the sanding pad 5 and four driving pins 3 and four bolt holes 8.
  • a larger or smaller number of driving pins 3 and 8 screw holes can be selected. It is also possible to choose a different sequence of driving pins 3 and 8 screw holes.
  • Essential to the invention is merely that the driving pins 3 and the screw holes 8 are arranged on a common circle about the central axis of the bearing flange 2 and equidistant to each other. It does not matter whether a through hole 12 meets a driving pin 3 or a screw hole 8.
  • a very simple mounting of the sanding pad 5 on the position flange 2 is possible by a sanding pad according to the invention, at the same time a wrong assembly is avoided.
