Automatic cleaning device and method for valve plate sealing face of piston refrigeration compressor

Abstract

The invention discloses an automatic cleaning device and method for a valve plate sealing face of a piston refrigeration compressor. The cleaning device comprises a machine frame and a rail plate fixed to the machine frame. A material feed bin is arranged on the rail plate. A material push mechanism is arranged on one side of the material feed bin. A guide rail is arranged on the other side of the material feed bin. A brush used for cleaning the valve plate sealing face is arranged above the guide rail. A power mechanism connected with the brush and making the brush reciprocate is arranged on the machine frame. The material push mechanism, the power mechanism and a discharge mechanism are all connected with a PLC. A first position sensor connected with the PLC is arranged on the portion, located on one side of the brush, on the rail plate. A second position sensor connected with the PLC is arranged one side of a discharge rail, right opposite to the outlet of the guide rail, on the guide plate. By means of the automatic cleaning device and method, the sealing performance of the valve plate sealing face can be effectively improved, and the refrigerating capacity of the compressor can be improved.

Description

technical field [0001] The invention relates to a cleaning process technology for the sealing surface of a high-precision valve plate, more specifically, the invention relates to an automatic cleaning device and a cleaning method for the sealing surface of a valve plate of a piston refrigeration compressor. Background technique [0002] Currently, if image 3 and Figure 4 As shown, in the refrigerator compressor industry, the commonly used technology for cleaning the sealing surface of the compressor valve plate is: the rotary brush is directly installed on the power head of the machine tool, and the compressor valve plate is positioned and fixed through the workpiece positioning seat to allow the rotary brush to The high-speed rotation of the type brush brushes the valve plate valve line; because the brush can only rotate in one direction during the scrubbing process, the valve plate valve line is ground by diamond high-speed rotating abrasive grinding, resulting in failur...

AI Technical Summary

Problems solved by technology

Because the valve line of the valve plate is processed by grinding, there are tiny burrs on the surface, and the burrs are along the processing direction of the previous process; so when the rotating brush brushes the surface, because its movement is in the same direction Yes, such a relative running track pair also has consistent tiny burrs that cannot be completely cleaned when brushing; resulting in tiny burrs on the ground surface, and the processed workpiece will still have exhaust valve seals due to burrs and scratches. leakage
