Air-conditioner compressor crank shaft fixture

Abstract

The invention discloses an air-conditioner compressor crank shaft fixture which comprises a base, a locating device and a clamping device, and is characterized in that a sliding groove is formed in the base; a pair of ejector pin brackets is arranged on the sliding groove; rotating hand wheels are arranged on the ejector pin brackets; the locating device comprises a locating table and a locating groove; the locating table is arranged on the base; the locating groove matched with a crank shaft in shape and size is formed in the locating table; the crank shaft is placed on the locating groove; the clamping device comprises a pair of pressing jaws and a pair of ejector pins; the pair of pressing jaws is respectively arranged on the left and right sides of the crank shaft on the locating table; the ejector pins are vertically fixed on the ejector pin brackets; and the pair of ejector pins is in contact with and is propped against the two ends of the crank shaft respectively. The air-conditioner compressor crank shaft fixture is simple in structure, convenient to mount, and low in cost, the operation method is easy to master, the working efficiency is greatly improved, the locating precision is high, and the clamping force is good.

Description

technical field [0001] The invention relates to the field of crankshaft tooling, in particular to an air conditioner compressor crankshaft fixture. Background technique [0002] The fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. When processing workpieces on machine tools, in order to make the surface of the workpiece reach the size, geometric shape and other Due to the technical requirements such as the mutual position accuracy of the surface, the workpiece must be installed and clamped firmly before processing. The crankshaft is a key part of the air-conditioning compressor. It is used to transmit power and cooperates with the connecting rod to form a crank-connecting-rod linkage mechanism, which converts the rotational motion of the prime mover into the reciprocating motion of the piston. The crankshaft’s out-of-tolerance will affect the life an...
