[0036] The present application is used for processing and clamping the trigger movable groove positioning hole of the military electromagnet core 5. First, the front positioning block 2 and the rear positioning block 3 are fixed by the positioning base 1, and then the anti-rotation positioning of one end of the electromagnet core 5 is realized by the plug-in cooperation of the limit slot 4 and the fixed magnet core, so as to realize radial fixation. The drilling 7 equipment drills downward through the top drill sleeve 6 and the drill hole 7 to process the trigger movable groove positioning hole of the electromagnet core 5. The other end of the electromagnet core 5 is supported on the V-shaped supporting groove 8 and then clamped by the clamping assembly 9.
