[0001] The present invention relates to the technical field of brake disc polishing, and specifically to a multi-angle surface polishing treatment device for automotive brake discs. Background Technique

[0002] The brake disc is a friction pair of a disc brake. In addition to having the strength and stiffness required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. The rotating element in the friction pair of a drum brake is the brake drum, with its cylindrical surface as the working surface; the rotating element in the friction pair of a disc brake is a disc-shaped brake disc, with its end face as the working surface.

[0003] During the production and processing of the brake disc of a disc brake, it is necessary to use a polishing device to polish the friction surface and the side surface of the brake disc. However, during the grinding operation of the existing polishing components, the synchronous grinding operation of the friction surface and the side surface of the brake disc cannot be carried out, and the grinding efficiency cannot meet the actual requirements. In view of the above technical defects of the existing technology, a multi-angle surface polishing treatment device for automotive brake discs is provided to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-angle surface polishing treatment device for automotive brake discs to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

Specific embodiments

[0024] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments:

[0025] First embodiment: Please refer to the attached Figure 1 - attached Figure 7A multi-angle surface polishing device for automobile brake discs, comprising a support platform 1, a support frame 3 is fixed on the support platform 1, a bearing tray 29 is installed on the support platform 1, a rotating sleeve 9 is coaxially fixed on the bearing tray 29, a brake disc 2 is sleeved on the rotating sleeve 9, a rotating shaft 7 is vertically slidably installed in the rotating sleeve 9, a sliding support block 27 is fixed at the bottom of the rotating shaft 7, a vertically arranged transmission column 13 is slidably installed in the rotating sleeve 9, a vertical spring 28 is fixed between the transmission column 13 and the sliding support block 27, and two symmetrically arranged translation frames are slidably installed on the support platform 1 14, a connecting rod 17 is hinged between the translation frame 14 and the transmission column 13, and a grinding assembly for grinding the side wall of the brake disc 2 is installed on the two translation frames 14. A vertically arranged rotating shaft 7 is rotatably installed on the support frame 3, a transmission sleeve 8 is slidably sleeved on the rotating shaft 7, and a lifting frame 6 is fixedly sleeved on the transmission sleeve 8. A clamping strip 20 slidably embedded in the inner wall of the transmission sleeve 8 is fixed on the side wall of the rotating shaft 7, and a locking stud 4 abutting against the rotating shaft 7 is threadedly connected to the side wall of the transmission sleeve 8. A polishing assembly for grinding the friction surface of the brake disc 2 is installed on the lifting frame 6.

[0026] When the brake disc 2 is polished by the device, the brake disc 2 is placed on the rotating sleeve 9, the brake disc 2 is supported by the carrying tray 29, and the side wall and friction surface of the brake disc 2 are polished by the grinding component and the polishing component respectively.

[0027] Specifically, the polishing assembly includes a sliding sleeve 30 fixed on the lifting frame 6, a vertical rod 32 is vertically slidably mounted on the sliding sleeve 30, a lifting plate 11 is fixed on the vertical rod 32, a push spring 26 is sleeved on the vertical rod 32, the two ends of the push spring 26 are respectively fixed on the sliding sleeve 30 and the lifting plate 11, and a polishing strip 12 corresponding to the friction surface of the brake disc 2 is fixed at the bottom of the lifting plate 11. A motor I5 is fixed on the support frame 3, and a pulley mechanism 16 is connected between the output shaft of the motor I5 and the rotating shaft 7.

[0028] Through the above arrangement, after the brake disc 2 is installed on the rotating sleeve 9, the lifting plate 11 under the lifting frame 6 is adjusted to drive the polishing strip 12 to move downward. Under the elastic action of the push spring 26, the polishing strip 12 can contact the upper surface of the brake disc 2, that is, the friction surface. Then, the locking stud 4 is screwed to lock and fix the rotating shaft 7 and the transmission sleeve 8. Under the driving action of the motor I5, the rotating shaft 7 is driven to rotate through the pulley mechanism 16, and the rotating shaft 7 drives the transmission sleeve 8 to rotate through the clamping strip 20. The transmission sleeve 8 drives the lifting frame 6 to rotate, and the lifting frame 6 drives the lifting plate 11 and the polishing strip 12 at the bottom to rotate, so as to realize the rotational polishing treatment of the friction surface of the brake disc 2.

[0029] Second embodiment: Please refer to the attached Figure 1 -AttachedFigure 7 , on the basis of the first embodiment, in addition, a partition 31 is fixed inside the transmission sleeve 8, and the transmission sleeve 8 is vertically corresponding to the sliding column 10. Before the transmission sleeve 8 moves vertically downward so that the polishing strip block 12 abuts against the friction surface of the brake disc 2, the partition 31 inside the transmission sleeve 8 pushes against the sliding column 10, causing the sliding column 10 to move vertically downward relative to the rotating sleeve 9. At this time, the vertical spring 28 drives the transmission column 13 to move vertically downward, and the transmission column 13 pulls the two translation frames 14 to slide towards the side wall of the brake disc 2 through the connecting rod 17, so that the grinding assembly can abut against the side wall of the brake disc 2 and perform polishing treatment.

[0030] After that, the transmission sleeve 8 continues to move downward, and the vertical spring 28 is compressed after being pushed by the sliding column 10. Finally, the polishing strip block 12 moves downward to abut against the upper surface of the brake disc 2. The above process realizes the coherent operation of the position adjustment of the polishing assembly and the grinding assembly, greatly improving the polishing processing efficiency of the brake disc 2.

[0031] In addition, the grinding assembly of the device includes a grinding block 23 slidably mounted on the translation frame 14. A connecting spring II 24 is fixed between the grinding block 23 and the translation frame 14. An elastic assembly is mounted on the translation frame 14, and a motor II 15 is mounted on the elastic assembly. A driving roller 19 is drivenly connected to the motor II 15. The elastic assembly includes a guide post I 22 fixed on the translation frame 14. A U-shaped frame 25 is slidably sleeved on the guide post I 22. A connecting spring I 21 is fixed between the U-shaped frame 25 and the translation frame 14. The driving roller 19 is rotatably mounted on the U-shaped frame 25. A horizontally extending traction spring coil 18 is fixed between the translation frame 14 and the support table 1.

[0032] Through the above settings, when the translation frame 14 moves towards the brake disc 2, the driving roller 19 first abuts against the side wall of the brake disc 2. Subsequently, the brake disc 2 slides towards the translation frame 14. Then, the grinding block 23 abuts against the side wall of the brake disc 2. Under the elastic action of the connecting spring II 24, the pressure between the grinding block 23 and the side wall of the brake disc 2 can be ensured, ensuring the polishing effect of the side wall of the brake disc 2. The provided motor II 15 can drive the driving roller 19 to rotate, and the driving roller 19 drives the brake disc 2 in frictional contact with it to rotate, and the rotation direction of the brake disc 2 is opposite to the rotation direction of the polishing strip block 12, greatly improving the polishing processing effect of the brake disc 2.

[0033] In summary, in the present invention, the friction surface and the side wall of the brake disc 2 are polished simultaneously by the arranged polishing strip blocks 12 and grinding blocks 23. The arranged motor II 15 can drive the driving roller 19 to rotate and drive the brake disc 2 to rotate, so that the brake disc 2 can rotate, achieving a sufficient polishing effect on the brake disc 2, greatly improving the polishing efficiency of the brake disc 2, and eliminating the need for separate step-by-step polishing of its friction surface and side wall. In the present invention, after the transmission column 13 is pushed against, the connecting rod 17 is used to pull the translation frame 14 to move towards the brake disc 2, so that the grinding block 23 on the translation frame 14 can abut against and limit the side wall of the brake disc 2, ensuring the stability of the brake disc 2 during rotation. Subsequently, the polishing strip block 12 moves vertically downward to contact the friction surface of the brake disc 2, achieving a coherent adjustment effect of the positions of the grinding block 23 and the polishing strip block 12, and effectively improving the polishing efficiency of the brake disc 2.
