[0002] Brake pads are key components used in automobile braking systems. The shear strength of brake pads is directly related to the stability and failure of the braking system. High shear strength and uniform quality between batches are the most basic requirements for brake pads.

[0003] In the related art, when processing brake pads, a shearing tool is usually needed to clamp the brake pads, but most of them require manual operation, so the degree of automation is low during the shear test of the brake pads. Utility Model Content

[0011] By adopting the above technical solution, you only need to place the brake pad in the slot to drive the clamping assembly to clamp the brake pad. After clamping, by driving the sliding assembly, the sliding drive drives the shearing knife to shear the brake pad. During the entire process of brake pad shearing, the staff only needs to manually take and place the brake pad, and the rest of the work is completed automatically, thereby improving the degree of automation of brake pad shearing.

[0029] or,

[0030] The first limit clamp is fixedly connected to the processing table; the guide limit rod is fixedly connected between the first limit clamp and the side clamp; the second limit clamp is slidably connected to the guide limit rod; the other end of the sliding rod is fixedly connected to the processing table.

[0032] The linear motor is mounted on the second limit clamping plate, and the main side clamping plate is mounted on the mover of the linear motor; the sliding direction of the main side clamping plate is perpendicular to the extension and retraction direction of the driving cylinder.

[0039] 1. The purpose of setting the placement seat, the clamping assembly and the sliding assembly is that the brake pad only needs to be placed in the slot to drive the clamping assembly to clamp the brake pad.

[0040] 2. The purpose of setting the first limit clamping plate, the guide limit rod and the second limit clamping plate is that when the driving cylinder is extended, the first limit clamping plate and the second limit clamping plate drive the sliding rod to move synchronously, so that after the main side clamping plate clamps the brake pad, the pressure plate can be placed at the shear knife.

[0041] 3. The purpose of setting the linear motor is to adjust the height of the main side clamping plate so that the main side clamping plate can better clamp brake pads of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
