Technical Field
[0001] This utility model relates to the field of brake pad grinding technology, specifically a brake pad production grinding device. Background Technology
[0002] Brake pads consist of a steel plate, a heat insulation layer, and friction blocks. When braking, the brake pads are squeezed, causing the friction blocks to press against the brake disc or brake drum. The friction helps to slow down and stop the vehicle. In actual manufacturing, to improve the performance of brake pads, they are polished to remove burrs or refine excess dimensions. This requires ensuring stability during the polishing process to avoid misalignment or uneven brake pad dimensions. Utility Model Content

The rear end is movably fitted with the shaft in the groove, and the front end is fitted with the threaded part on the shaft. After the workpiece to be ground is placed in the placement groove, the knob is manually turned to drive the threaded shaft to rotate. Since the threads on the left and right sides are symmetrical, the two fitted clamping plates will approach each other and clamp the workpiece to be processed.
[0004] As a preferred technical solution of this utility model, the stabilizing part includes a stabilizing shaft and a stabilizing through hole. Specifically, the stabilizing shaft is fixedly installed on the rear side wall inside the side slide. The sliding rod has a through hole in the front and rear directions and is fitted onto the stabilizing shaft through the through hole. The bottom surface of the opening groove is inclined, with the lower side near the front opening and the higher side at the rear.
[0005] As a preferred technical solution of this utility model, the uniform speed moving structure is configured such that a front frame is fixed on the front side of the bottom surface of the worktable, and a front ring is formed in the middle of the front frame. A rear mounting plate is integrally formed on the rear side of the bottom surface of the worktable. A motor is fixedly installed on the rear side of the rear mounting plate. This motor is powered by an external power supply and is a motor capable of forward and reverse rotation. It is equipped with an intelligent controller, such as a PLC controller. The output shaft of the motor extends from the through hole in the center of the rear mounting plate to the front end and is fixedly connected to the lead screw at its end. The unthreaded part of the front end of the lead screw is movably inserted into the front ring, and the outer wall of the lead screw contacts the inner wall of the front ring. This structure is used to maintain the stability of the lead screw rotation. An assembly plate is integrally formed in the middle of the rear side of the bottom surface of the base plate, and the assembly plate is installed in conjunction with the lead screw.
[0006] As a preferred technical solution of this utility model, the rear mounting plate has a through groove in the front and rear directions, and the baffle passes through the through groove. Its front end is fixed on the rear side of the mounting plate. The baffle is located above the lead screw, and the baffle can prevent grinding debris from falling onto the lead screw.
[0007] As a preferred technical solution of this utility model, the outer wall of the knob has anti-slip grooves, and anti-slip strips are distributed on the inner side of the clamp plate. The anti-slip strips are made of polyurethane.
[0008] The beneficial effects of this utility model are as follows: The workpiece to be ground is clamped in the placement groove by the inner shaft, knob and clamping plate. Then, the uniform speed moving structure is set to send it stably and uniformly into the grounding disc under the rotating grinding disc. The hydraulic lift is started in advance to lift the workpiece to be ground so that it can smoothly contact the grinding disc to be ground. The workpiece to be ground will move under the grinding disc to be ground. Some of the debris falls into the placement groove and enters the opening groove through the trough.

The height of the clamps is lower than the thickness of the workpiece to be ground to avoid contact with the grinding disc. Start the hydraulic lift to adjust the height of the workpiece to be ground so that it can smoothly contact the grinding surface of the grinding disc. When the motor on the rear side starts, it drives the lead screw to rotate, causing the mating plate and the base plate to move together, so that the workpiece to be ground moves and is ground at a uniform speed under the grinding disc. The area of the grinding disc is larger than that of the workpiece to be ground, so that the grinding can be carried out evenly during the movement.
