Problems solved by technology

[0003] The valve body of the expansion valve needs to be pickled after welding to prepare for the surface treatment of the valve body. The pickling operation of the valve body is generally to put a basket of the valve body into the pickling pool by driving, so that the valve body is immersed in The acid solution reacts with the oxides on the surface of the valve body. Since the valve bodies are put in one basket by one basket, the driving operation is inconvenient. At the same time, the loading and unloading of the basket is more troublesome, which greatly affects the processing efficiency of the expansion valve.

Abstract

The invention discloses a machining device for producing external balance thermal expansion valves of a QPW5 automobile air conditioner. The machining device comprises an acid liquid pool, a support column arranged on one side of the acid liquid pool, a rotating disc arranged on the support column, carrier trays arranged on the rotating disc and a mounting frame arranged above the acid liquid pool; a hydraulic cylinder is arranged on the mounting frame; a push rod is arranged on a piston rod of the hydraulic cylinder; a first drive motor for driving the rotating disc to rotate is arranged on the support column; a plurality of first through cavities matched with the carrier trays are formed in the rotating disc; a second drive motor for driving the push rod to rotate is arranged on the piston rod of the hydraulic cylinder; and a first connecting groove matched with the push rod is formed in each carrier tray. The rotating disc and the push rod are matched with each other, so that the carrier trays full of valve bodies continuously rotate to the position above the acid liquid pool, the difficulty of loading, unloading and replacing the carrier trays is reduced, the carrier trays areable to work continuously, and the efficiency of machining the valve bodies is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and in particular relates to a processing equipment for producing externally balanced thermal expansion valves for QPW5 automobile air conditioners. Background technique [0002] The expansion valve is an important part in the refrigeration system, generally installed between the liquid storage cylinder and the evaporator. The expansion valve makes the medium-temperature and high-pressure liquid refrigerant become low-temperature and low-pressure wet steam through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect. The expansion valve controls the flow rate of the valve through the change of the superheat at the end of the evaporator to prevent Insufficient utilization of evaporator area and knocking phenomenon. [0003] The valve body of the expansion valve needs to be pickled after welding to prepare for the surface treatment of ...
