Special device for reaming crankcase stator pin

Abstract

Disclosed is a special device for reaming a crankcase stator pin. The special device for reaming the crankcase stator pin comprises a lathe bed (1). The lathe bed (1) is of a rectangular box structure. A hydraulic sliding platform (2) is arranged at one end of the upper surface of the lathe bed (1), and a base is arranged at the other end of the upper surface of the lathe bed (1). A clamp (3) is arranged on the base and is used for fixing the processed crankcase stator pin (5) to the base. A main shaft (6) is arranged on the portion, corresponding to the crankcase stator pin (5), of the top of the hydraulic sliding platform (2). A special cutter head (4) is arranged between the main shaft (6) and the crankcase stator pin (5). By the adoption of the special device for reaming the crankcase stator pin, the stator pin is firmly fixed to the machine base through the special clamp, one-time forming of the working surface of the crankcase stator pin is achieved by the use of the special cutter head, and the plane accuracy of the obtained working surface of the stator pin is high.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and more specifically, relates to a special device for the stator foot of a countersink crankcase. Background technique [0002] The compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the movement of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. So as to realize the refrigeration cycle of compression-condensation-expansion-evaporation. [0003] At present, most of the compressors of household refrigerators are positive displacement compressors, which can be divided into reciprocating compressors and rotary compressors. The main components include crankcases, pistons, crankshafts, connecting rods and motors. The crankcase serves as the base of the entire structure, ...

AI Technical Summary

Problems solved by technology

[0005] (1) With traditional machining methods such as turning or milling, the flatness precision of the working surface of the stator foot obtained by processing is not high, the roughness is poor, and it is difficult to meet the processing accuracy requirements;

[0006] (2) The crankcase structure of the refrigerator compressor is complex, and the machining such as turning or milling of the stator foot surface is relatively difficult, the process is relatively complicated, and the processing efficiency is low.

[0007] (3) The clamping safety risk of turning or milling processing is too high, which may easily cause safety accidents for workers

[0008] (4) The processing from the blank to the finished product has a long production cycle and is not suitable for mass production. Moreover, the quality of the blank tends to deteriorate with the increase in the use time of the mold
