Description

Technical Field

[0001] The invention relates to the technical field of brake pad production, in particular to a material surface grinding and molding device used for the development of brake pads. Background Art

[0002] During the production process of brake pads, the brake pads need to be polished. The purpose of polishing is to make the brake pads and brake discs work better together and ensure the good operation of the brake system. However, excessive polishing will make the brake pads thinner, which will bring safety hazards. At the same time, the grooves on the surface of the brake pads can quickly discharge the powder debris generated by the wear of the brake pads and brake discs, avoiding the debris from adhering to the friction surface between the brake pads and the brake discs, causing the brake discs to be scratched and affecting the braking effect. When the existing grinding devices are in use, most of them use a linear conveyor to transport the brake pads to the bottom of the grinder for grinding. During the transportation process, two linear baffles installed on the conveyor are used to position and guide the linear planes on both sides of the brake pads to ensure that the brake pads will not move during grinding. This method requires manual and precise placement of the brake pads between the two linear baffles in actual production. Otherwise, the brake pads will become skewed during transportation, affecting the grinding efficiency of the brake pads. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

In the process of the fixture for clamping the brake pad 7 being transferred to the grinding station, the top block 5 moves radially outward until the brake pad 7 is pressed tightly against the stop block 4; when it is transferred to the grinding station, it stops rotating, and then the grinder 6 is controlled to descend, and the grinding station is clamped. The brake pad 7 on the position is ground and processed. After the grinding is completed, the grinder 6 is controlled to rise, and the workstation disc 2 continues to rotate to make the brake pad 7 clamped upstream turn to the grinding station. When the ground brake pad 7 is turned to the unloading station, the top block 5 moves radially inward to release the clamping fixation of the brake pad 7, and the brake pad 7 can be removed. Through the above-mentioned arrangement, the groove 8 and the positioning protrusion 10 are utilized to automatically position the brake pad 7 when the top block 5 pushes the brake pad 7 outward. The loading is simple, and there is no need to fix the brake pad 7 with high precision. One person can complete the loading and unloading, which saves manpower, has a high degree of automation, and improves the grinding efficiency.

The two ends of the inner circular groove 22 are connected to the two ends of the outer circular groove 21 through the linear groove 23 respectively. The inner circular groove 22 corresponds to the loading station and the unloading station, and the outer circular groove 21 corresponds to the grinding station. Specifically, the outer plate 20 is fixedly mounted on the chassis 18 by bolts. In this embodiment, when the work station 2 rotates, the chassis 18 remains fixed, so that the guide post 15 moves in the guide groove. When the guide post 15 moves to the inner circular groove 22, the guide post 15 moves inward along the strip groove 14, which is convenient for loading and unloading; when the guide post 15 moves to the outer circular groove 21, the guide post 15 moves outward along the strip groove 14, and the brake pad 7 is clamped and fixed.

The tensioning force of the abrasive belt 29 is convenient for disassembling and assembling the abrasive belt 29; when the linear cylinder 34 contracts, the first connecting rod 33 pushes the bearing seat 27 upward, so that the tensioning wheel 28 moves upward, and the tensioning force of the abrasive belt 29 is increased at this time; through the above arrangement, it is convenient to adjust the tensioning force of the abrasive belt 29, and by providing the second slide rail 31 and the second slide block 32, the tensioning force of the abrasive belt 29 is reduced and directly applied to the output end of the linear cylinder 34 through the first connecting rod 33; compared with directly using the cylinder to vertically push the bearing seat 27 up and down, the cylinder in this embodiment does not need to be subjected to force in real time, so as to avoid the tensioning force acting directly on the cylinder, protect the cylinder, and extend the service life of the cylinder; In order to facilitate the adjustment of the lifting of the integrated board 24, Figure 1 , Figure 8 As shown in the positioning protrusion 10 of the figure, two groups of connecting ears 38 are symmetrically arranged at the bottom of the integrated board 24, and a second connecting rod 39 is rotatably installed on each group of connecting ears 38.
