Automatic piston feeding machine for variable displacement compressor

Abstract

The invention relates to the technical field of machinery, in particular to an automatic piston feeding machine for a variable displacement compressor. The automatic piston feeding machine for the variable displacement compressor comprises a machine frame, a charging tray moving mechanism, a piston jacking mechanism, a charging tray trolley, a piston discharging mechanism, a piston overturning mechanism, and a piston front side and back side inspecting mechanism. The automatic piston feeding machine for the variable displacement compressor is characterized in that the charging tray moving mechanism is arranged in front of the machine frame, the piston overturning mechanism is arranged on the machine frame and is located behind the piston jacking mechanism, the piston discharging mechanism is arranged on the machine frame and is located above the piston overturning mechanism, and the piston front side and back side inspecting mechanism is arranged on the machine frame and is located on the left side of the piston discharging mechanism. Compared with the prior art, the provided automatic piston feeding machine has the advantages that the automatic piston feeding machine is controlled by a PLC in the whole production process, and actions in each process are calculated accurately and executed in place; meanwhile, due to the fact that the piston front side and back side inspecting mechanism is arranged, the piston placing speed is guaranteed, placement faces of pistons are kept consistent, working efficiency is greatly improved, and labor cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an automatic piston feeder for variable displacement compressors. Background technique [0002] When manufacturing piston-type variable-displacement automotive air-conditioning compressors, the first process is to place the piston at the specified position and install the piston ring. Among them, placing the piston at the specified position is now all done by workers. However, the operation by workers has the following disadvantages: manual placement of pistons requires high work intensity, and it is difficult to meet the requirements of the production cycle (21 seconds) for a long time; each compressor needs 6 to 7 pistons, and two workers are needed to complete the placement of pistons The production cost is high; because workers wear gloves, foreign matter management is difficult, and foreign matter is easily attached to the surface of the piston; lack of error-proof mecha...
