[0002] The brake pad, also called the brake shoe, is the most critical safety part in the braking system of an automobile. The quality of all braking effects is determined by the brake pad. The brake pad is generally composed of a steel plate, an adhesive heat insulation layer and a friction block. The heat insulation layer is composed of heat-insulating materials for the purpose of heat insulation; the friction block is composed of friction materials and adhesives. When braking, it is squeezed against the brake disc and brake drum to generate friction, so as to achieve the purpose of vehicle deceleration and braking. During the manufacturing process of the brake pad, its surface needs to be ground. Therefore, it needs to be processed by a grinding device.

[0003] The patent document with the publication number of CN117754410A discloses a brake pad grinding device, which includes a support seat, and a self-locking worm is rotatably installed on the support seat; guide gears are fixedly installed at the front and rear ends of the self-locking worm; a self-locking worm gear is rotatably installed on the left side inside the support seat; a positioning seat is slidably installed on the left side of the top of the support seat. This grinding device can synchronously realize the sealing and two clamping and positioning operations of the brake pad during the necessary step of bringing the brake pad into contact with the grinding disc, ensuring the safety during the grinding process of the brake pad.

[0004] However, the defect of the grinding device in the above-mentioned prior art is that when grinding and processing the brake pad, the brake pad needs to be fixed on one side of the positioning disc, and then the surface of the brake pad is ground by the grinding disc. However, when the above-mentioned grinding device works, it can only grind one side of the brake pad, resulting in low grinding efficiency. Summary of the Invention

[0005] Aiming at the above problems, a grinding device for processing brake pads is provided. The brake pad body is placed outside one end of the feeding rod, and the brake pad body is fixed by the top block. Then the mounting disc is rotatably installed inside the first grinding component and the second grinding component, and a number of rotatable circular abrasives are arranged on one side of the mounting disc, so that the first grinding component and the second grinding component can be closed, so that the circular abrasives inside the first grinding component and the second grinding component respectively abut against both sides of the brake pad body, and then the circular abrasives grind both sides of the brake pad body, realizing the simultaneous grinding of both sides of the brake pad body by the grinding device, and solving the problem that the grinding device cannot grind both sides of the brake pad body simultaneously.

[0006] To solve the problems of the existing technology, the present utility model provides a grinding device for processing brake pads, including a base. One end of the top of the base is fixed with a first grinding assembly, and a second grinding assembly is movably arranged on one side of the top of the base close to the first grinding assembly. A second cover plate is arranged on one side of the second grinding assembly. A feeding rod is arranged at the center of one side of the second cover plate, and a brake pad body is installed at one end of the feeding rod. Rotatable mounting disks are respectively installed inside the tops of the first grinding assembly and the second grinding assembly. An annular limiting groove is arranged inside the edge of one side of the mounting disk, and a plurality of second annular limiting sliding rails for limiting are fixed near the edge of the other side of the mounting disk. A circular abrasive for simultaneously grinding both sides of the brake pad body is movably installed outside the second annular limiting sliding rails, so that the first grinding assembly and the second grinding assembly can be closed, so that the circular abrasives inside the first grinding assembly and the second grinding assembly respectively abut against both sides of the brake pad body, and further the circular abrasives grind both sides of the brake pad body.

[0007] As a technical solution of the present utility model, limiting rings are fixed inside the first grinding assembly and the second grinding assembly. An internal toothed belt is arranged inside the limiting rings, and a first annular limiting sliding rail capable of being adapted to the annular limiting groove is arranged on one side of the limiting rings, so that the mounting disk rotates along the first annular limiting sliding rail through the annular limiting groove.

[0008] As a technical solution of the present utility model, a driven gear capable of meshing with the internal toothed belt is fixed outside the circular abrasive, so as to improve the grinding efficiency of the circular abrasive on the surface of the brake pad body.

[0009] As a technical solution of the present utility model, rotation driving parts are respectively installed inside the bottoms of the first grinding assembly and the second grinding assembly. A driving gear is arranged at the output end of the rotation driving part, so that the rotation driving part drives the driving gear to rotate.

[0010] As a technical solution of the present utility model, an external toothed belt capable of meshing with the driving gear is arranged at the edge of the mounting disk, so that the driving gear drives the mounting disk to rotate through the external toothed belt while rotating.

[0011] As a technical solution of the present utility model, a first cover plate is arranged on one side of the first grinding assembly. A spline shaft is fixed at the center of one side of the first cover plate. One end of the spline shaft is movably installed with a push block. One end of the push block is fixed with a spring, and the other end of the spring is fixed on the surface of the first cover plate. The other end of the first cover plate is movably installed with a top block for abutting against the brake pad body, so that the spring pushes the top block to abut against the side surface of the brake pad body through the push block, and prevents the brake pad body from falling off during grinding.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

[0013] In this application, the brake pad body is placed outside one end of the feeding rod and fixed by the top block. Then, the mounting disc is rotatably installed inside the first grinding assembly and the second grinding assembly, and a number of rotatable circular abrasives are arranged on one side of the mounting disc, enabling the first grinding assembly and the second grinding assembly to close. As a result, the circular abrasives inside the first grinding assembly and the second grinding assembly respectively abut against both sides of the brake pad body, and then the circular abrasives grind both sides of the brake pad body, achieving simultaneous grinding of both sides of the brake pad body by the grinding device and solving the problem that the grinding device cannot simultaneously grind both sides of the brake pad body.

[0023] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-8 As shown, a grinding device for processing brake pads includes a base 1.
