Problems solved by technology

[0004] The broaching process with constant force and constant speed will easily cause poor broaching, leaving waves on the seat plane, which will easily cause poor sealing between the valve seat and the main slide valve, and affect the service life of the four-way reversing valve
The main reasons are: 1) During the constant force broaching process, the load of the tool fluctuates greatly first and then slightly, which leads to uneven force on the tool during the broaching process, which easily causes tool vibration, which causes poor broaching; 2) Constant force broaching In the process of high-speed broaching, the displacement of the tool is constant, resulting in a constant vibration frequency of the tool, which is easy to cause resonance, and resonance causes poor broaching

Abstract

The invention provides a processing device of a valve seat plane and a processing method. The processing device of the valve seat plane comprises a servo motor, a cutter and a closed-loop control mechanism; the servo motor is connected with the cutter through a connection assembly to drive the cutter to process a valve seat; the closed-loop control mechanism is in communication connection with theservo motor and controls target output of the servo motor according to load information of the cutter in a closed loop mode. By means of the processing device of the valve seat plane, fluctuation ofthe cutter in the broaching process can be obviously reduced, and resonance between the cutter and a main valve body is avoided; vibration of the cutter in the broaching process is conveniently reduced, raised grains are conveniently prevented from being generated on the valve seat plane, and accordingly the broaching qualification rate is conveniently increased. The processing method is used forprocessing the valve seat plane by using the processing device of the valve seat plane.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing of a four-way reversing valve, in particular to a processing device and a processing method for a valve seat plane. Background technique [0002] The four-way reversing valve is an indispensable part of the heat pump air conditioner and is used to switch the flow direction of the refrigerant. The four-way reversing valve includes a valve seat and a main slide valve. The contact surface between the valve seat and the main slide valve is the seat plane, and the main slide valve can slide along the seat plane to switch the flow path to realize the cooling and heating switching of the air conditioner. In order to ensure a good seal between the valve seat and the main slide valve during switching, there is a high requirement for the flatness of the seat plane, and the surface roughness of the slide seat plane needs to reach Rz0.8. Therefore, it is necessary to broach the seat pla...
