[0034] Working principle: Before welding, the push rod 12 is started to extend the push rod 15, and then the clamp 16 moves toward the direction of the motor. After the clamp 16 completely contacts the motor, the guide plate 17 will also adhere to the surface of the motor. During the welding process, welding slag will fall everywhere. Because the surface of the guide plate 17 is a smooth curved surface, it can guide the welding slag to a certain extent during the falling process of the welding slag; after the push rod 12 is started to extend the push rod 15, the clamp 16 will move toward the direction of the motor. During the movement of the clamp 16, the first cross plate 2 will rotate and apply a force to the second cross plate 22 toward the push rod 15. The force will be dispersed to the clamp plate 23 through the second cross plate 22, so that the clamp plate 23 is subjected to the force toward the push rod 15; before the clamp 16 clamps the motor, The rubber nail 32 will first enter the heat sink groove of the motor.

When the push rod 15 is extended, it will drive the vertical plate 44 to move together. The vertical plate 44 will squeeze the oil storage bag 42 during the movement. The lubricating oil in the oil storage bag 42 will be sprayed onto the surface of the hinge shaft through the first hose 43 to achieve lubrication of the hinge shaft; water is injected into the waste pool 5. During the welding process of the motor, welding slag will splash everywhere. Since the top of the buffer column 52 is a conical structure, it will have a certain buffering and guiding effect on the landing of the welding slag, so that the welding slag can fall slowly and accurately to the waste pool. By setting up a waste pool 5 in the pool 5, the welding slag can be collected and processed when it falls; when the motor is welded, the welding slag will fall into the waste pool 5, causing the water in the waste pool 5 to evaporate and generate a large amount of water vapor. After starting the air pump 6, the water vapor can be absorbed and processed through the fixing hole 62, and it can also absorb part of the smoke generated during the welding process; when the air pump 6 collects and processes the exhaust gas generated by the device, part of the welding slag will fall onto the surface of the buffer plate 7, and the buffer plate 7 will have a certain buffering and guiding effect on the falling of the welding slag, so that the welding slag can fall slowly and accurately into the waste pool 5, while reducing the damage to the fixing hole 62 caused by the impact of the waste slag; before clamping the motor, the length of the screw 82 in the support seat 1 can be adjusted by screwing the bolt head 8, and finally the level of the working surface of the device can be achieved.
