[0017] The utility model provides a kind of air compressor valve plate precision polishing equipment. With following beneficial effects:

[0018] The present scheme is based on the background technology proposed above, as the air compressor valve plate in the market is different in size and specification according to different purposes, so when precision polishing different air compressor valve plates, the clamp for fixing air compressor valve plate in precision polishing equipment needs to be replaced with the clamp corresponding to air compressor valve plate. When disassembling the air compressor valve plate, the air compressor valve plate is located between two precision polishing devices. Therefore, it is often necessary to first remove the equipment shell, and then remove a precision polishing device, so that the air compressor valve plate can be disassembled and replaced. The disassembly and replacement process is very complicated, which results in a very long time for disassembling and replacing the air compressor valve plate. During the disassembly and replacement of the air compressor valve plate, the entire equipment is in a shutdown state, thus greatly slowing down the efficiency of the precision polishing equipment when precision polishing air compressor valve plates in batches. The present scheme first places the air compressor valve plate that needs to be precision polished into a rotary feeder, then starts the precision polishing device and the valve plate fixing disc. The precision polishing device starts to rotate the valve plate fixing disc. The rotary feeder sequentially feeds the air compressor valve plate that needs to be precision polished into the valve plate fixing disc. The valve plate fixing disc feeds the air compressor valve plate that needs to be precision polished into the equipment main body by rotating. Then, the precision polishing device is used to precision polish both sides of the air compressor valve plate that needs to be precision polished. The valve plate fixing disc continues to rotate and takes out the precision polished air compressor valve plate from the equipment main body.

[0019] When the valve plate fixing disc needs to be replaced, first, the rotary feeder and the precision polishing device are closed. Then, the moving part of the disc fixing mechanism is started to move the disc fixing mechanism away from the equipment main body using the rack. When the disc fixing mechanism moves to the fixed groove away from the equipment main body, the position of the disc fixing mechanism at this time is fixed using the fixed groove away from the equipment main body. Then, the valve plate fixing disc that needs to be replaced can be taken out from the disc fixing mechanism. Then, the new valve plate fixing disc is placed into the disc fixing mechanism. Subsequently, the disc fixing mechanism is started to move towards the equipment main body. When the disc fixing mechanism returns to its original position, the position of the disc fixing mechanism at this time is fixed using the fixed groove in the equipment main body. Then, the new air compressor valve plate can be precision polished, which reduces the time needed for replacing the valve plate fixing disc and thus improves the efficiency of precision polishing air compressor valve plates in batches.

[0020] When the mobile platform needs to be started, the first motor is started, the first gear and the rack are matched with each other, the platform main body is driven to move, the roller is responsible for supporting the platform main body and reducing the friction force during movement, when the platform main body moves to a specified position, the first hydraulic rod is started, the first sliding block is away from one end of the first hydraulic rod and enters the fixed groove, the position of the platform main body is further fixed, and accidental movement of the platform main body is prevented, so that the staff is not damaged.

[0021] The second hydraulic rod moves the lifting block to the direction close to the mobile platform, then the wedge surface of the wedge-shaped pressing block extrudes the double-wedge-shaped sliding block, the double-wedge-shaped sliding block is moved to the direction close to the elastic circular ring, the double-wedge-shaped sliding block extrudes the wedge surface of the elastic circular ring inner part, then the double-wedge-shaped sliding block completely enters the elastic circular ring, the position of the elastic circular ring is fixed, the direction and the moving speed of the elastic circular ring can be controlled through the telescopic fixing column, and the elastic circular ring is fixed, so that the elastic circular ring is prevented from being damaged due to accidental loss of control.

[0022] When the telescopic fixing column moves away from the mobile platform, the parts of the telescopic fixing column are away from the fourth sliding groove and the wedge-shaped groove inside, the circular ring main body moves away from the mobile platform through the second spring, the circular ring main body pushes out the valve plate fixing disc from the disc fixing mechanism, and the valve plate fixing disc is convenient for workers to disassemble and replace.

[0023] When the positioning machine needs to enter the closed state, first, the second motor is started, the sliding block moves to the direction close to the second motor, the second rotating plate rotates around the rotating bearing, then the second rotating plate drives the pressing plate to move to the direction close to the threaded rod, the pressing plate drives the first rotating plate to repeat the movement process of the second rotating plate, and all the pressing plates can be driven to move through one motor.
