A top spring 13 is fixedly assembled on the outer wall of the cross frame 3.

[0022] By providing the fixed cylinder 4 in the inner cavity of the cross frame 3 and rotatably connecting the ball 5 to the inner wall of the fixed cylinder 4, the outer wall of the ball 5 contacts the outer wall of the telescopic rod 6, so that when the telescopic rod 6 is pushed to move inward along the inner wall of the fixed cylinder 4, it can be more convenient and faster under the action of the rotation of the ball 5, so as to better clamp the workpiece.

[0023] In a preferred embodiment: a chute is provided on the outer wall of the telescopic rod 6, and the inner wall of the chute contacts the outer wall of the ball 5.

[0024] By providing the chute on the outer wall of the telescopic rod 6, when the telescopic rod 6 is driven to move inward under the action of the driving gear 10 and the toothed plate 7, the ball 5 can move along the outer wall of the telescopic rod 6, so as to realize the rolling friction between the outer wall of the telescopic rod 6 and the outer wall of the ball 5, and thus better drive the telescopic rod 6 to move inward under the action of the driving gear 10.

[0025] In a preferred embodiment: the outer wall of the driving gear 10 meshes with the outer wall of the toothed plate 7, and the driving motor 9 is a low-speed high-torque motor.

[0026] By providing the driving gear 10 on the outer wall of the power output shaft of the driving motor 9, the telescopic rod 6 can be driven to move inward or outward along the outer wall of the fixed cylinder 4 under the action of the driving gear 10. When the telescopic rod 6 is pulled outward under the action of the driving gear 10, the top spring 13 will be compressed. When the telescopic rod 6 moves inward to clamp the workpiece, it can play a role in releasing the top spring 13.

[0027] In a preferred embodiment: The control board 8 is electrically connected between the drive motor 9 and the electromagnetic brake lock 11 respectively, and a rubber buffer pad is fixedly assembled on the inner wall of the clamping plate 12.

[0028] By arranging the electromagnetic brake lock 11 on the outer wall of the power output shaft of the drive motor 9, the drive motor 9 can be locked under the action of the electromagnetic brake lock 11, so as to fix the position of the telescopic rod 6, and further realize the clamping and fixing of the workpiece, and better carry out the welding operation.

[0029] In a preferred embodiment: One end of the top spring 13 away from the cross frame 3 is connected to the outer wall of the clamping plate 12, and the rest length of the top spring 13 is less than the outer wall length of the telescopic rod 6.

[0030] By arranging the top spring 13 between the outer walls of the clamping plate 12 and the cross frame 3, when the telescopic rod 6 is moved outwards under the action of the drive gear 10, the top spring 13 will be compressed. When the clamping plate 12 is used to clamp the workpiece, by cutting off the power supply of the drive motor 9 and releasing the electromagnetic brake lock 11, at this time, the clamping plate 12 will move inwards under the action of the top spring 13, so as to realize the clamping of the workpiece.

[0031] In a preferred embodiment: There are two drive motors 9, and the two drive motors 9 are respectively arranged on the outer walls on both sides of the cross frame 3.

[0033] Working principle: During the use of the above device, when welding a workpiece is required, first release the electromagnetic brake locks 11 on both sides. At this time, start the drive motor 9 under the action of the control board 8. Under the action of the drive motor 9, drive the rotation of the drive gear 10. At this time, move the telescopic rod 6 outwards. During the process of moving the telescopic rod 6 outwards, the clamping plate 12 will also move outwards and compress the top spring 13, so that the clamping plates 12 on both sides directly move apart a certain distance. Then the workpiece to be clamped can be placed in the middle of the cross frame 3. Then power off the control board 8. At this time, the clamping plate 12 will quickly clamp the workpiece under the action of the top spring 13. After clamping the workpiece, depending on the clamping situation of the workpiece, decide whether to start the drive motor 9 again and continue to push the clamping plate 12 inwards under the action of the drive motor 9 to achieve a more secure clamping effect on the workpiece. Then lock the electromagnetic brake lock 11 through the control board 8. Under the action of the electromagnetic brake lock 11, lock the power output shaft of the drive motor 9. At this time, clamping of the workpiece can be achieved. When it is necessary to release the clamping, first release the lock of the electromagnetic brake lock 11, and then reverse the drive motor 9 to pull the clamping plate 12 outwards to release the workpiece.
