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 produced in such a way that the brush set, which consists, for example, of one or more disk-like brush elements, is arranged between a multiplicity of pressed metal parts. This construction has been used by all brush manufacturers to date and is still used in a variety of similar forms today.
- the invention is therefore based on the object of designing the brush of the generic type in such a way that a considerable reduction in material costs can be achieved with simplified manufacture and at the same time an even lower weight, combined with further handling advantages, can be achieved.
- the features of the invention created to achieve this object result from claim 1.
- Advantageous refinements thereof are described in the further claims.
- the configuration is such that the tensioning disks each have an axial collar on their mutually facing side, the outer or inner diameter of which is dimensioned such that, when tensioning disks are fastened to one another, the axial collar of one tensioning disk connects to that of the other tensioning disk Formation of the tensioning disc connection engages and at the same time the cylindrical holding element is formed for mounting the brushes.
- This embodiment is based on the essential idea of the invention, not only to provide the axial collars of the two clamping disks for mounting the brushes, but also to design them in such a way that they themselves fix the two clamping disks to one another. This can easily be achieved with simple means in terms of production technology, so that this ensures a simple and secure connection of the tensioning disks.
- the axial collars of the two clamping disks have the same length or that they have different lengths.
- the engagement connection between the axial collars of the two clamping disks can be formed by a fitting or clamping connection.
- the arrangement can be such that the engagement connection between the axial collars of the two tensioning disks is formed or secured by adhesive which is applied to at least one of the interacting circumferential surfaces of the axial collars.
- the fitting or clamping connection between the axial collars is formed in that at least one of the axial collars has elevations, in particular in the form of axial ribs, on its circumferential surface interacting with the other axial collar.
- the axial ribs are provided on the outer peripheral surface of the smaller-diameter axial collar.
- the axial ribs are arranged at the same circumferential distance from one another, since this also achieves a uniform clamping effect over the circumference of the axial collars.
- the axial ribs are chamfered on their front free end face.
- the axial collar that receives the axial ribs is chamfered on its front end face.
- the axial collar receiving the axial ribs carries at its front end an annular bead which, when tensioning disks are attached to one another engages behind the axial ribs of the other axial collar formed with a predetermined length.
- the larger axial collar advantageously has axially extending longitudinal ribs on its outer circumferential surface.
- the tension discs are made of glass fiber reinforced plastic. It is within the scope of the invention that the clamping disks are injection molded parts. 120 Overall, significant advantages can be achieved with the rotary brush according to the invention, which include the following:
- Fig. 1 shows schematically in section the one clamping disc of the rotary brush according to the invention
- Fig. 3 shows schematically in section the rotary brush with the two clamping discs in the fixed state.
- the rotary brush provided for the surface treatment of workpieces has two clamping disks 1, 2 which are designed differently in the exemplary embodiment shown, but can also be of the same design.
- the two clamping disks 1, 2 each have an axial collar 3 or 4 on their side facing each other Fig. 3 of the axial collar 3 of the spring washer 1 155 engages in the axial collar 4 of the spring washer 2 to form the spring washer connection.
- this forms a cylindrical holding element for storing a brush set 5 (see FIG. 3).
- This is designed in the usual manner with wire bristles 7 held in cross-sectionally U-shaped clamping elements 6.
- the configuration is such that the axial collar 3 of the tensioning disk 1 has a greater length than the axial collar 4 of the tensioning disk 2 and is of smaller diameter, i.e. thus at its outer circumferential surface at most reaches the diameter of the inner circumferential surface 165 of the axial collar 4 of the tensioning disk 2.
- the engagement connection between the axial collars 3, 4 of the two clamping washers 1, 2 is achieved by a fitting or clamping connection, namely in that the smaller diameter axial collar 3 ⁇ o of the clamping washer 1 has a plurality of axial ribs 8 on its outer circumferential surface - shown in FIG Embodiment has two axial ribs 8 -, which are arranged at the same circumferential distance from each other. Due to the presence of these axial ribs 8, there is the effect that the axial collar 3 of the spring washer 1 has a larger overall outer circumferential surface
- the axial ribs 8 are chamfered on their front free end face 9.
- the axial collar 4 of the other tensioning disk 2 which receives the axial ribs 8 of the axial collar 3, is chamfered on its front end face 10.
- the larger diameter axial collar 4 has at its front end an annular bead 11 which, when the clamping discs 1, 2 are fixed to one another, has the axial ribs 8 of the axial collar 3 engages securely.
- the axial ribs 8 are formed with a correspondingly large predetermined length, so that the function of the rear engagement is ensured. This can be seen particularly clearly from FIG. 3.
- the larger diameter axial collar 4 of the tensioning disk 2 has axially extending longitudinal ribs 12 on its outer circumference.
- eight longitudinal ribs 12 are provided at the same circumferential distance from one another, which ensures a secure and non-slip storage of the brush stock.
- punctiform projections 13 which are arranged in greater numbers on the mutually facing inner surface of the tensioning disks 1, 2.
- the clamping disks 1, 2 are made of glass fiber reinforced plastic and can advantageously be formed as injection molded parts.
- the tensioning disks 1, 2 have predetermined recesses 14 on their outer surface, which are provided as labeling and marking surfaces.
- the described embodiment is basically designed as a non-detachable connection of the tensioning disks 1, 2, it is of course also possible, if desired, 215 to make the configuration such that the connection between the tensioning disks 1, 2 can subsequently be released, for example with the aid of a suitable tool with which the described securing of the connection can be canceled.
