Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve core technology, and more specifically to electromagnetic valve core assembly equipment. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common are check valves, safety valves, directional control valves, and speed regulating valves. Solenoid valves consist of multiple parts and require assembly before use.

[0003] Existing solenoid valve cores are usually assembled manually. However, when assembling solenoid valve cores manually, it is easy to cause improper pressing, which affects the assembly stability of the solenoid valve core. Manual assembly is not stable enough during welding and the appearance is poor. Furthermore, the air gap adjustment during the assembly process of solenoid valve cores is unstable and inconvenient.

[0004] Therefore, a solenoid valve core assembly device is proposed to solve the above problems. Utility Model Content
