Swash plate air conditioner compressor piston ball socket processing fixture

Abstract

The invention discloses a swash plate air conditioner compressor piston ball socket processing fixture which comprises a bottom plate, a linkage device, connecting rods, a fixture seat, a positioningseat I, a fixed seat, a loading ejector rod, an unloading ejector rod, an axial positioning sleeve, hydraulic cylinder sleeves and hydraulic clamping jaws. The fixture seat, the positioning seat I andthe fixed seat are sequentially arranged on the side, on which one long side is located, on the bottom plate from left to right; the linkage device is arranged on the side, on which the other long side is located, on the bottom plate; a processing through slot is formed in the middle of the fixture seat along the short side direction of the bottom plate; the two hydraulic cylinder sleeves are symmetrically arranged on the left side and the right side of the fixture seat; one hydraulic clamping jaw is arranged in each hydraulic cylinder sleeve in an interference way; a pressing plate is arranged on the top part of the fixture seat; the axial positioning sleeve is arranged on the hydraulic cylinder sleeve located on the left side of the fixture seat in an interference way; the unloading ejector rod is arranged in the axial positioning sleeve in an inserting way; the loading ejector rod is arranged on the fixed seat; and the loading ejector rod and the unloading ejector rod are connectedwith the linkage device through connecting rods. The swash plate air conditioner compressor piston ball socket processing fixture has the characteristics of simple and reasonable structure, simplicity and convenience in positioning, and high positioning accuracy.

Description

technical field [0001] The invention relates to a jig for processing a piston ball socket, in particular to a jig for processing a piston ball socket of a swash plate type air conditioner compressor. Background technique [0002] The automobile air-conditioning compressor is the heart component of the automobile air-conditioning system. The piston of the compressor reciprocates in the cylinder bores of the front and rear cylinders to complete the four processes of expansion, suction, compression and exhaust of the residual gas in the cylinder. Most of the existing automobile air-conditioning compressors adopt the swash plate type automobile air-conditioning compressor, and the two ends of the piston of the swash-plate type automobile air-conditioning compressor are in the shape of a cylinder, the middle is a swash plate socket, and there are ball sockets on both sides of the swash plate socket , when the swash plate rotates, the inclined plane has an axial displacement, and ...

AI Technical Summary

Problems solved by technology

Since the ball socket is set on both sides of the socket of the piston swash plate, the shape of the piston is a cylindrical structure. When the piston is placed through the V-shaped seat, the center of the piston will directly change due to the change of the outer diameter of the piston, and the outer diameter of the piston is passed through. Cylindrical grinding machine processing will always change within the tolerance in mass production, so it will greatly reduce the positioning accuracy of the piston ball socket, which will seriously affect the processing accuracy of the ball socket and greatly reduce the product qualification rate

At present, in order to improve the coaxiality between the center of the piston ball socket and the center of the outer circle of the piston, the consistency of the outer diameter of the piston is ensured, which not only makes the operation difficult, but also greatly increases the processing cost
