[0034] The inner wall of the guide slot 401 is T-shaped, and the inner wall of the guide slot 401 is slidably connected with a guide rail 402 whose surface is fixedly connected to the upper surface of the welding workbench 1 .

[0035] When in use, the guide rail 402 and the guide slot 401 cooperate to guide the movable mounting platform 4 .

[0036] A bearing seat 403 fixedly connected to the upper surface of the welding workbench 1 is arranged between the two guide rails 402 , and the two bearing seats 403 are symmetrically distributed with the axis of the guide rail 402 as the center.

[0048] Working principle: When friction welding is performed on the copper sheet and the aluminum column, the aluminum column is clamped by the three-jaw chuck 303, and the copper sheet to be welded is clamped by the copper sheet chuck 407 in cooperation with the pneumatic clamp 406. Then, the welding drive motor 301 and the mobile drive motor 405 are automatically controlled by the controller 2 to work. The output shaft of the welding drive motor 301 drives the three-jaw chuck 303 to rotate, and the mobile drive motor 405 drives the drive screw 404 to rotate through the coupling.

The movable mounting table 4, the pneumatic clamp 406 and the copper sheet are contacted with one end of the aluminum column for friction welding. After the welding is completed, the mobile drive motor 405 is reversed to drive the movable mounting table 4 away from the three-jaw chuck 303. Then the controller 2 controls the gas rod in the material receiving cylinder 5 to extend, driving the material receiving box 501 to move upward, close to the electrode after welding, and then the three-jaw chuck 303 releases the clamping of the aluminum column, and the welded electrode falls into the material receiving box 501 and rolls into the material receiving hose 503 for unloading. Then the material receiving cylinder 5 drives the material receiving box 501 to reset, ready for friction welding again.
