Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a brake pad steel back processing fixture. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the braking system of a car. The quality of all braking effects is determined by the brake pads. When processing the steel back of the brake pad, it is generally necessary to use a clamp to fix it in order to facilitate its processing.

[0003] However, when the existing brake pad steel back clamp is actually used, people will find that it is difficult to replace the surface to be processed during the processing of the brake pad steel back. Therefore, some people think of setting a rotating mechanism on the clamping mechanism. For example, the Chinese utility model patent with announcement number CN212824902U specifically discloses a clamp for processing the brake pad steel back.

[0004] However, in actual use of the above-mentioned brake pad steel back processing fixture, people will find that the spacing between the clamping components on both sides of the device is fixed, which makes it difficult for the device to clamp and fix brake pad steel backs of different sizes, and it is difficult for the device to change the clamping height of the brake pad steel back, which greatly reduces its practicality.

By withdrawing the locking screw from the positioning socket, the height of the C-shaped frame can be adjusted, thereby adjusting the clamping height of the brake pad steel back, and the brake pad steel back can be fixed by the C-shaped frame and the clamping plate.

[0008] Preferably, supporting legs are provided at the corners below the bottom plate, and the provided supporting legs mainly play a supporting role.

[0009] Preferably, the slider is slidably connected to the slide rail, and the slide rail is used to limit the lead screw slider to prevent the lead screw slider from rotating along with the bidirectional lead screw.
