Description

Technical Field

[0001] This patent relates to the technical field of brake processing, specifically a polishing device for a caliper disc brake. Background Art

[0002] The brake is an indispensable part of an automobile. However, today's brakes are usually of a caliper disc structure. In order to improve the heat dissipation effect of the brake disc, heat dissipation holes are provided on the brake disc. After the heat dissipation holes are opened, in order to improve the flatness of the friction surface between the brake disc and the friction block, a grinding and polishing device is used to grind and polish the brake disc. An electric motor is provided on the existing device, and two polishing discs are installed on the rotating shaft of the electric motor for simultaneously grinding the top surface and the bottom surface of the brake disc. However, if there are burr protrusions on the surface of the brake disc to be ground, these protrusions will prevent the two polishing discs from being sleeved on the brake disc, making it inconvenient for installation. Therefore, we propose a polishing device for a caliper disc brake. Utility Model Content

Detailed Embodiment

[0018] The present patent will be further elaborated below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present patent and not to limit the scope of the present patent. In addition, it should be understood that after reading the content taught by the present patent, those skilled in the art can make various changes or modifications to the present patent, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0019] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 are schematic structural diagrams of the present patent. A polishing device for a disc brake includes a base 1. A column 2 is fixedly installed at the top of the base 1. A brake disc is provided at the top of the column 2. An L-shaped seat 3 is integrally formed on the left side of the top of the base 1. A cylinder 4 is fixedly installed at the bottom of the L-shaped seat 3. A pressing plate 5 is fixedly installed at the bottom end of the piston rod of the cylinder 4. A motor 6 is fixedly installed on the right side of the top of the base 1. A rotating rod 7 is fixedly installed at the top end of the rotating shaft of the motor 6. A polishing disc 8 is installed on the side wall of the rotating rod 7. The number of the polishing discs 8 is two. The two polishing discs 8 are respectively attached to the top surface and the bottom surface of the brake disc.

[0020] An installation groove 9 is provided at the top end of the rotating rod 7. Through holes 10 are provided at both the left and right ends of the side wall of the installation groove 9. A fixing plate 11 is fixedly installed on the inner side wall of the installation groove 9. One end of a spring 12 is fixedly installed at both the top and the bottom of the fixing plate 11. The other end of the spring 12 is fixedly installed with a pulling plate 13. A square hole is provided in the middle of the polishing disc 8. The inner side wall of the square hole is slidably installed on the side wall of the rotating rod 7. The left and right ends of the pulling plate 13 are respectively fixedly installed on the left and right ends of the inner side wall of the square hole.

[0021] Figure 3 As shown in the figure, the spring 12 is in a stretched state. Through the resilience effect of the spring 12, the two polishing discs 8 are attached to the top surface and the bottom surface of the brake disc.

[0022] Specifically, a limiting ring 14 is integrally formed on the side wall of the rotating rod 7. The number of the limiting rings 14 is two. The outer side surfaces of the two limiting rings 14 are respectively attached to the inner side surfaces of the two polishing discs 8.

[0023] Figure 3 In, by providing two limiting rings 14, the distance between the two polishing discs 8 at this time is the normal thickness of the brake disc, avoiding excessive wear of the brake disc by the polishing discs 8 due to the resilience of the spring 12.

[0024] Specifically, a circular groove 15 is provided at the top of the pressing plate 5. A bearing 16 is provided in the circular groove 15. The outer side wall of the outer ring of the bearing 16 is fixedly installed on the inner side wall of the circular groove 15. The top end of the inner ring of the bearing 16 is fixedly installed with a connecting block 17. The top end of the connecting block 17 is fixedly installed at the bottom end of the piston rod of the cylinder 4.

[0025] During the grinding process, the pressure plate 5 can be rotated, and then the brake disc can be rotated, which is convenient for grinding and polishing different positions at the edge of the brake disc.

[0026] Specifically, a plug post 18 is integrally formed at the bottom edge of the pressure plate 5, and the plug post 18 is inserted into the mounting hole of the brake disc.

[0027] By setting the plug post 18 to be inserted into the mounting hole of the brake disc, it is used to increase the connection between the pressure plate 5 and the brake disc.

[0028] Specifically, a conical surface is provided at the bottom end of the plug post 18.

[0029] The setting of the conical surface can make the bottom end of the plug post 18 smaller, which is convenient for the plug post 18 to be inserted into the mounting hole of the brake disc when moving downward.

[0030] Specifically, a blower 19 is fixedly installed at the bottom of the L-shaped seat 3.

[0031] After grinding and polishing are completed, the brake disc can be cooled by blowing air through the blower 19.

[0032] Working principle: When burr protrusions appear at the end of the heat dissipation holes of the brake disc, the two polishing pads 8 will be lifted up. The motor 6 drives the polishing pads 8 to rotate, and the rotating polishing pads 8 grind and polish the burr protrusions on the brake disc. After grinding and polishing, the polishing pads 8 will fit on the limiting ring 14 to avoid excessive wear on the brake disc caused by the return force of the spring 12.

[0033] It should be noted that the device structure and drawings of this patent mainly describe the principle of this patent. On the basis of this design principle, the settings of the power mechanism, power supply system and control system of the device are not fully described clearly. However, on the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system and control system can be clearly known.

[0034] In this patent, an installation groove is provided at the top end of the rotating rod, and a fixing plate is installed in the installation groove. Both the top and bottom of the fixing plate are connected to a pulling plate through springs, and the pulling plate is fixed on the inner side wall of the polishing pad. If burr protrusions appear on the brake disc, the two polishing pads can be pulled to make the two polishing pads move away from each other, which is convenient for the two polishing pads to be sleeved on the top and bottom surfaces of the brake disc, facilitating the installation.
