[0030] As shown in the drawings, Figures 1 to 4 The utility model discloses an automatic polishing brush device 1, including mounting plate 11, fixed frame 12, roll brush 13 and power part 14, mounting plate 11 is connected with fixed frame 12, roll brush 13 is movably arranged on mounting plate 11, roll brush 13 is transmission connection with power part 14, and it rotates under the drive of power part 14, and roll brush 13 is located above the tooth rolling processing roller 3, when working, roll brush 13 rolls to clean the surface of tooth rolling processing roller 3.

[0031] Roll brush 13 has brush and brush shaft, and the brush is the part of roll brush 13 and tooth rolling processing roller 3 surface contact, plays the role of cleaning, polishing or polishing etc. Brush can be metal brush or synthetic material brush (such as nylon, polypropylene etc.), and the arrangement of brush can be perpendicular to brush shaft, also can be helical, staggered arrangement etc.

[0032] Power part 14 can be stepper motor, servo motor, motor etc., and the output shaft of power part 14 is connected with roll brush 13. In order to realize the independent operation of power part 14 according to the need, control device can be configured, is responsible for monitoring, control power part 14's start, stop and operating parameter. Control device can be PLC, microcontroller or special control circuit etc.

[0033] According to the need, the independent cleaning of tooth rolling processing roller 3 can be set before processing or during processing. Of course, according to the specific setting condition, cleaning can be carried out, for example, the interval time of setting cleaning is carried out periodically and regularly.

[0034] Through the roll brush 13 set, the tooth rolling processing roller 3 can be cleaned before processing or during processing, avoid the problem that the metal scrap and oil stain are easily left on the tooth rolling processing roller 3, reduce the defective rate of parts.

[0035] As shown in the drawings, Figure 1 , Figure 4As shown, in one embodiment, the axis of rotation of the roller brush 13 is parallel to the axis of rotation of the thread rolling roller 3. This design allows the roller brush 13 to more evenly cover the surface of the thread rolling roller 3, increasing the contact area with the thread rolling roller 3. This effectively removes metal shavings, oil stains, and other residues from the surface of the thread rolling roller 3, ensuring comprehensive and uniform cleaning. Furthermore, when the roller brush 13 rotates along an axis parallel to the thread rolling roller 3, the relative motion between the bristles and the surface of the thread rolling roller 3 is smoother, reducing excessive friction and mechanical stress, thereby reducing wear on the surface of the thread rolling roller 3 and the roller brush 13, and extending the service life of both.

[0036] In one embodiment, the rotation axis of the roller brush 13 is offset from the rotation axis of the thread rolling roller 3 , and the rotation axis of the roller brush 13 is located behind the rotation axis of the thread rolling roller 3 .

[0037] Specifically, when the axis of the roller brush 13 is offset from the axis of the thread rolling roller 3, the two will not be completely aligned, reducing the interference of the thread rolling roller 3 on the normal operation of the roller brush 13 during the operation of the equipment. In addition, the contact area between the bristles of the roller brush 13 and the thread rolling roller 3 is relatively reduced, and the sliding phenomenon of the contact point will also be reduced, thereby improving the efficiency and effect of the cleaning process.

[0038] In one embodiment, the width of the roller brush 13 is greater than the width of the thread rolling roller 3. This design allows the roller brush 13 to completely cover the entire width of the roller, thereby improving cleaning efficiency.

[0039] In addition, the bristles can extend beyond the edge of the thread rolling roller 3 to effectively clean the edge of the roller. The edge of the thread rolling roller 3 is prone to accumulation of debris or sundries, and the wider roller brush 13 can better remove the residue at these locations.

[0040] like Figure 3 As shown, the mounting plate 11 is provided with two bearing mounting seats 15 at relative intervals, the two bearing mounting seats 15 are respectively provided with bearings 16, the two bearings 16 are provided with shafts 17, the roller brush 13 is installed on the shafts 17, and one end of the shafts 17 is connected to the power part 14.

[0041] Specifically, the dual bearings 16 support effectively prevent the roller brush 13 from shaking or vibrating during operation, ensuring the stability of the roller brush 13 during operation, thereby improving the accuracy of cleaning or processing. Furthermore, the dual bearings 16 support design significantly reduces the rotational resistance of the shaft 17, allowing the power element 14 to more efficiently drive the roller brush 13. The bearings 16 effectively support and guide the rotation of the shaft 17, reducing energy loss and improving transmission efficiency.

In this way, the structural stability of the mounting plate 11 is ensured, and the mounting plate 11 can better absorb and disperse the vibration and impact generated during the operation of the equipment, especially when the roller brush 13 rotates at high speed, which can effectively reduce the vibration of the equipment and improve the stability and precision of the work. In addition, one bearing mounting seat 15 is arranged on the first side plate part 112, and the other is arranged on the inner plate part 114, instead of the traditional two-side arrangement, so that the distribution of the bearings 16 is more reasonable, and this design can better balance the stress of the shaft rod 17, especially for long shaft rods 17, which can effectively prevent the middle part of the shaft rod 17 from sagging and improve the stable operation of the roller brush 13.

[0043] In this embodiment, the length of the second side plate part 113 is greater than that of the first side plate part 112, and the power member 14 is mounted on the second side plate part 113.
