Description

Technical Field

[0001] The invention relates to the technical field of machining machine tools, in particular to a high-precision numerical control machining machine tool for a solenoid valve core. Background Art

[0002] Solenoid valves are widely used in automatic control of water, gas, oil, etc. The solenoid valve core is an important component that is movably arranged inside the solenoid valve. By energizing the electromagnet, the solenoid valve core is driven to move, thereby controlling the opening and closing of the solenoid valve and realizing pipeline control. The solenoid valve core is mostly a long cylindrical rod. In order to adapt to other functions such as positioning and limiting, the side wall of the solenoid valve core can be set with ring grooves of different specifications and other structures.

[0003] In the prior art, the solenoid valve core is mostly processed by a high-precision CNC machine tool. The machine tool usually includes a rotating seat that is rotatably set to fix the solenoid valve core, and a milling seat with a tool. The solenoid valve core is fixed on the rotating seat, and the rotating seat is driven to rotate by a driving component. The milling seat is moved so that the tool contacts the rotating solenoid valve core, thereby processing the solenoid valve core.

[0004] In actual use, the solenoid valve core may have a certain length, and the side wall of the solenoid valve core with a considerable length needs to be processed during the processing. Therefore, the solenoid valve core can only be fixed at a position close to one end of the solenoid valve core, which makes the solenoid valve core not fixed firmly enough, and it is easy to cause the solenoid valve core to shake during the processing, thereby affecting the processing accuracy.
