Definitions

  • the invention relates to a rotary brush for surface treatment of workpieces according to the preamble of claim 1.
  • Known rotating round brushes are usually manufactured in such a way that the brush trimmings, which for example consist of one or more disc-like Brush elements exist between a variety of pressed metal parts is arranged. This construction has been used by all brush manufacturers so far is used and is still used today in a variety of similar forms applied.
  • the invention is therefore based on the object of the brush of the generic type Type in such a way that with simplified production a considerable Reduction in material costs is achievable and at the same time an even smaller one Weight, combined with other handling advantages, can be achieved.
  • the configuration is such that that the tension discs each have an axial collar on their side facing each other have whose outer or inner diameter is dimensioned such that the axial collar of one of the tensioning disks is attached to one another connecting in that of the other spring washer to form the spring washer connection engages and at the same time thereby the cylindrical holding element is formed for storage of the brush trimmings.
  • This configuration is based on the essential idea of the invention, the Axial collars of the two spring washers not only for storing the brushes to provide, but to design them in such a way that they themselves determine the two washers together. This is easy to do with Achieve simple manufacturing techniques, so that this is a simple and secure connection of the clamping washers is guaranteed.
  • both washers have the same length or that they are different Have length.
  • the engagement connection between the axial collars of the two spring washers can be formed by a fitting or clamping connection. Instead or in addition the arrangement can be made such that the engagement connection formed by adhesive between the axial collars of the two spring washers or is secured on at least one of the interacting with each other Circumferential surfaces of the axial bundle is applied.
  • the passport or Clamping connection between the axial collars formed in that at least one of the axial collars on its interacting with the other axial collar Has circumferential surface elevations, in particular in the form of axial ribs. This are when pressing the two washers, for example by means of a 20 t press, with the force of the associated one Circumferential surface of the other axial collar effectively connected, so that this achieved the desired secure connection between the spring washers becomes.
  • axial ribs on the outer circumferential surface of the smaller diameter axial collar intended.
  • lightening washers in the initial stage can be provided be that the axial ribs beveled on their front free end face are.
  • one Axial collar which receives the axial ribs, bevelled on its front face is.
  • the two washers to separate from each other at a later time, it corresponds to one advantageous embodiment of the invention that the receiving the axial ribs Axial collar at its front end carries an annular bulge, which at one another fixed washers the axial ribs formed with a predetermined length engages behind the other axial collar.
  • the larger diameter expediently bears it Axial collar on its outer peripheral surface axially extending Longitudinal ribs.
  • tension washers are made of glass fiber reinforced plastic consist. It is within the scope of the invention that the clamping washers Are injection molded parts.
  • the two clamping disks have 1, 2 each have an axial collar 3 or 4 on their side facing each other
  • the outer or inner diameter is such that when attached to each other Spring washers 1, 2 according to FIG. 3, the axial collar 3 of the spring washer 1 connecting in the axial collar 4 of the spring washer 2 to form the spring washer connection intervenes.
  • this creates a cylindrical holding element formed for storing a brush set 5 (see Fig. 3).
  • This is in the usual way with held in cross-sectionally U-shaped clamping elements 6 Wire bristles 7 designed.
  • the configuration is such that that the axial collar 3 of the spring washer 1 has a greater length than that Axial collar 4 of the clamping disc 2 and is made smaller in diameter, i.e. on its outer peripheral surface, the maximum diameter of the inner peripheral surface of the axial collar 4 of the spring washer 2 reached.
  • the engagement connection between the Axial collars 3, 4 of the two clamping washers 1, 2 by a fitting or clamping connection achieved, namely in that the smaller diameter axial collar 3rd the clamping disc 1 on its outer peripheral surface a plurality of axial ribs 8 - in Embodiment shown two axial ribs 8 - which in the same Circumferential distance from each other are arranged. Because of the presence this axial ribs 8 thus results in the effect that the axial collar 3 of Spring washer 1 a larger overall on its outer peripheral surface Diameter than the axial collar 4 of the other spring washer 2 on its inner peripheral surface having. This results in an effective fitting or clamping connection, when the two tension washers 1, 2 are joined together and are attached to each other so that the axial collar 3 is pressed into the axial collar 4 becomes.
  • the axial ribs 8 are free at their front Face 9 chamfered.
  • the one receiving the axial ribs 8 of the axial collar 3 is also used Axial collar 4 of the other spring washer 2 on its front face 10 beveled.
  • the larger diameter axial collar 4 has on its front end of an annular bead 11, which is fixed to each other Spring washers 1, 2 securely engage behind the axial ribs 8 of the axial collar 3.
  • the axial ribs 8 are predetermined with a correspondingly large size Length formed so that the function of the rear grip is ensured. This can be seen particularly clearly from FIG. 3.
  • the larger diameter carries Axial collar 4 of the clamping washer 2 axially extending on its outer circumference Longitudinal ribs 12.
  • eight longitudinal ribs 12 are in the same Circumferential distance from each other is provided, which ensures safe and non-slip storage of the brush trim guaranteed.
  • the washers 1, 2 are made of glass fiber reinforced plastic and can advantageously be formed as injection molded parts.
  • the tensioning disks 1, 2 are attached their outer surface predetermined recesses 14, which are used as labeling and marking surfaces are provided.
  • the described embodiment is basically an inseparable connection of the spring washers 1, 2 is designed, it goes without saying if desired also possible to make the design such that the connection between the washers 1, 2 can be released subsequently, for example then with the help of a suitable tool with which the described fuse the connection can be broken.
