Brake pads usually need to be cut, ground and processed during processing to ensure their surface smoothness and reduce wear. In order to improve processing efficiency and ensure processing quality, a fixed fixture is needed to fix the brake pads for processing. After searching, Chinese patent announcement number: CN218170111U discloses a fixed fixture for brake pad processing, including a base plate and a clamping table; the base plate: a track is arranged on its upper surface, a slide is slidably connected to the upper surface of the track, the lower left and right ends of the slide are respectively located in the corresponding limit grooves opened on the left and right surfaces of the track, the upper surface of the slide is fixedly connected to a vertical plate, the left side of the upper surface of the base plate is fixedly connected to a frame, and the inner right side of the frame is fixedly connected to a mounting plate; the clamping table: there are two of them, and the rotating shafts arranged on the back sides of the clamping table are rotatably connected to the left side wall of the vertical plate and the right side wall of the mounting plate through the first bearing respectively, and the bottom walls of the grooves opened on the opposite sides of the clamping table are rotatably connected to the lower end of the threaded rod through the second bearing. The fixed fixture for brake pad processing can meet the requirements of stable and appropriate clamping and fixing of brake pads of different sizes, and the brake pad can be rotated in the clamping state, which is convenient for all-round processing of the brake pad.

[0003] Although the above device can meet the requirements of stable and appropriate clamping and fixing of brake pads of different sizes, it can only adjust one set of clamping tables to move closer to the other set of clamping tables, and cannot adjust the two sets of clamping tables at the same time. This causes the fixed brake pad to be unable to be in the center position of the base plate. When processing is required, it may be necessary to adjust the position of the processing device separately, which is troublesome and it is troublesome to fix. The threaded rod needs to be frequently turned when fixing or disassembling. Therefore, a fixing fixture for brake pad processing is proposed to solve the above problems. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a fixing fixture for brake pad processing, which aims to improve the problem in the prior art that the fixing is troublesome and requires frequent rotation of the threaded rod. Although it can fix brake pads of different sizes, it cannot fix them in the center position, affecting subsequent operations.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a fixing fixture for brake pad processing, comprising a workbench, a clamping seat is slidably connected to the outer wall above the workbench, the clamping seat is fixedly connected to a central axis at one inner end, a rectangular plate is fixedly connected to the end of the central axis, two groups of clamping blocks are slidably connected to the outer wall of the rectangular plate, two groups of guide rods are slidably connected to the inner walls of the two groups of clamping blocks, a circular disc is fixedly connected to the outer wall of the central axis, a slide groove a is provided on the inner wall of the circular disc, a cylindrical block is fixedly connected to the back of the clamping block, a turntable is rotatably connected to the outer wall of the central axis, a slide groove b is provided on the inner wall of the turntable, and a buckle assembly is elastically connected to the inner wall of the turntable via a reset spring.

[0006] As a further description of the above technical solution: The upper outer wall of the workbench is rotatably connected with a threaded rod, the end of the threaded rod is fixedly connected with a knob, the outer wall of the threaded rod is threadedly connected with two groups of threaded sleeves, and the outer wall of the threaded sleeve is hinged with a bracket.

[0007] As a further description of the above technical solution: The buckle assembly comprises a clamping block, and the inner wall of the disc is provided with a plurality of clamping grooves.

[0008] As a further description of the above technical solution: The outer wall of the columnar block is slidably connected to the inner wall of the slide groove a.

[0009] As a further description of the above technical solution: The inner wall of the slide groove b is slidably connected to the outer wall of the columnar block.

[0010] As a further description of the above technical solution: The end of the bracket is fixedly connected to an inner end of the clamping seat.

[0011] As a further description of the above technical solution: One end of the return spring is fixedly connected to the inner end of the clamping block, and the other end of the return spring is fixedly connected to the inner wall of the rotating disk.

[0012] As a further description of the above technical solution: The outer wall of the clamping block is clamped with the inner wall of the clamping slot.

[0013] The present invention has the following beneficial effects: 1. In the present invention, by setting a knob, when it is necessary to fix brake pads of different sizes, the knob is turned to rotate the threaded rod, so that the threaded sleeves are brought closer to or separated from each other until the angle of the bracket is offset, thereby pulling the two groups of clamping seats closer to or separated from each other, and the two groups of clamping seats can be adjusted at the same time, so that the brake pads are fixed at the center position of the workbench, which is convenient for subsequent equipment to process.

[0014] 2. In the present invention, a turntable and a clamping block are provided. When the brake pad needs to be fixed, the clamping block is pressed inward until it is disengaged from the clamping slot. Then, the turntable is rotated to make the slide slot b drive the column block to slide along the slide slot a, and drive the clamping blocks to move closer to each other to fix the brake pad. After fixing, the clamping block can be released. The adjustment method is simple and does not require frequent rotation of the threaded rod, thereby improving work efficiency.
