Description

Technical Field

[0001] The present invention relates to the technical field of spool processing, and particularly to a processing device for the inner hole of an automotive solenoid valve spool. Background Art

[0002] An automotive solenoid valve is an actuator of an electronic control system, usually composed of an electromagnetic coil and a spool component. By using electromagnetic force to control the opening and closing of the valve, precise control of various fluids or mechanical movements in the vehicle can be achieved, ensuring the normal operation of the vehicle.

[0003] With the continuous development of the automotive industry, the requirements for the performance, reliability, and safety of vehicles are increasing day by day. As a key component of the vehicle, the performance of the solenoid valve directly affects the operation of various vehicle systems. The machining accuracy of the inner hole of the spool is crucial for the performance of the solenoid valve. However, traditional machining methods are difficult to meet the machining requirements of high precision and high efficiency. At this time, a processing device for the inner hole of an automotive solenoid valve spool is needed.

[0004] Currently, the processing devices for the inner hole of automotive solenoid valve spools on the market mainly consist of a fixed fixture, a grinding tool, and a driver. When in use, the spool is fixed by the fixed fixture, and the driver drives the grinding tool to process the spool. However, in the grinding or grinding process of this device, it is difficult to ensure the coaxiality between the spool and the tool, resulting in insufficient cylindricity after the inner hole of the spool is processed, affecting the sealing performance of the solenoid valve. To solve the above problems, the prior art often adopts the method of adding a positioning device to improve the processing accuracy of the device. However, in actual use, this device adopts a sequential processing method, and the milling, drilling, turning, and grinding processes are scattered on different devices. The workpiece needs to be repeatedly clamped and positioned in each process, which will waste a lot of time during the clamping process, affecting the processing process of the spool.
