When the limit assembly unlocks the U-shaped plate 24, the limit plate 32 is pushed upward by the elasticity of the support spring 33, and the workpiece is pushed out of the U-shaped frame to realize the blanking function. The telescopic rod 31 is fixedly connected to a guide plate 36, and the guide plate 36 is sleeved on the outside of the connecting rod 22.

When the welding hand 12 moves to one side, the U-shaped rod in the opposite direction will move upward. When the wedge plate 42 moves upward and contacts the fixing plate 46, it continues to move upward, which will push the limit plate 41 to move into the U-shaped rod, thereby unlocking the limit plate 41.

[0025] The solution further provided by the present invention also includes an unlocking member.

A wedge block 53 is slidably set in the rectangular plate 52. The wedge block 53 is adapted to the wedge plate 42. The bottom end of the wedge plate 42 is L-shaped. When the wedge block 53 moves to above the wedge plate 42, the wedge plate 42 is limited to assist the movement of the limit plate 41. A limit spring 54 is fixedly connected to the rectangular plate 52, and the limit spring 54 is fixedly connected to the wedge block 53.

[0026] Furthermore, a limit block 55 is fixedly connected to the rectangular plate 52, a driving block 56 adapted to the limit block 55 is fixedly connected to the outside of the first screw rod 21, a torsion spring 57 is provided on the outer sleeve of the rotating rod 51, and both ends of the torsion spring 57 are fixedly connected to the welding table 1 and the rectangular plate 52 respectively.

[0027] In the present invention, a driving member is also included for driving the movement of the welding hand 12. The driving member includes a motor 61. The output end of the motor 61 is fixedly connected to a second screw 62. The second screw 62 is threadedly connected to the welding hand 12.

[0028] Furthermore, it also includes a connecting member for connecting the driving member and the clamping member, the connecting member includes a driving rod 71 rotatably arranged in the welding table 1, the top end of the driving rod 71 is fixedly connected to a driven bevel gear 75, the second screw 62 is fixedly connected to an active bevel gear 76 matched with the driven bevel gear 75, a rectangular rod 72 is slidably arranged in the first screw 21, the first screw 21 is matched with the rectangular rod 72, when the rectangular rod 72 rotates, the first screw 21 is driven to rotate synchronously, the rectangular rod 72 extends to the outside of the first screw 21 and is fixedly connected to a third gear 73, and a fourth gear 74 matched with the third gear 73 is fixedly connected to the outside of the driving rod 71.

[0029] During welding, the workpiece is placed in the U-shaped plate 24, and the driving motor 61 drives the second screw 62 to rotate, so that the welding hand 12 moves to the right (with a rotation angle of 1 / 400mm). Figure 1As a reference), at the same time, the second screw rod 62 rotates so that the active bevel gear 76 drives the driven bevel gear 75 to rotate, so that the driving rod 71 drives the fourth gear 74 to rotate, so that the third gear 73 rotates, and drives the rectangular rod 72 to rotate synchronously, so that the first screw rod 21 on the left side rotates and moves upward, and drives the connecting rod 22 to move upward synchronously through the connecting plate 23, and drives the two U-shaped frames to move upward synchronously. When the wedge plate 42 moves and contacts with the fixed plate 46, the U-shaped frame continues to move upward, so that the wedge plate 42 moves downward in the U-shaped frame, thereby pushing the limit plate 41 to move into the U-shaped plate 24, so that the reset spring 45 is compressed, thereby opening the U-shaped plate 24, and placing the unwelded workpiece into the U-shaped plate 24; When the welding hand 12 moves to the right, the first screw rod 21 on the right side rotates and moves downward in the welding table 1, thereby driving the connecting rod 22 to move downward synchronously through the connecting plate 23, so that the second gear 35 moves downward synchronously. When the second gear 35 moves down to mesh with the first gear 34, the second gear 35 rotates and drives the first gear 34 to rotate synchronously, thereby driving the telescopic tube to rotate, so that the guide plate 36 rotates and drives the connecting rod 22 to rotate 90°. At this time, the second gear 35 moves out of the first gear 34 to achieve bending of the workpiece. Then the first screw rod 21 continues to move downward, so that the workpiece contacts the limit plate 32 and moves downward, so that the support spring 33 is compressed, and at the same time the U-shaped frame drives the wedge plate 42 to move downward and contact the wedge block 53, and then the wedge plate 42 continues to move downward, pushing the wedge block 53 away from the wedge block 53, driving the limit spring 54 to compress, so that the wedge plate 42 moves down to the bottom of the wedge block 53, and then the limit spring 54 pushes the wedge block 53 to move to the top of the wedge plate 42, at this time the welding hand 12 moves to the far right, and then the motor 61 is turned off, and the welding hand 12 is used to weld the bending part of the workpiece; After welding is completed, the motor 61 is started to rotate in the reverse direction, so that the welding hand 12 moves to the left, and at the same time, the first screw rod 21 on the right rotates in the reverse direction and moves upward. Figure 5 As shown in the figure, when the U-shaped frame moves upward, the wedge block 53 is restricted, so that the wedge plate 42 moves downward in the U-shaped frame, thereby pushing the limit plate 41 out of the U-shaped frame, and pushing the limit plate 32 upward through the support spring 33 to push the welded workpiece out of the U-shaped frame; The first screw rod 21 continues to move upward to drive the driving block 56 to move upward and rotate. When the driving block 56 contacts the limiting block 55, the limiting block 55 is pushed to rotate, so that the wedge block 53 moves out of the wedge plate 42, so that the wedge plate 42 moves upward and resets. After the driving block 56 moves out of the limiting block 55, the elastic force of the torsion spring 57 pushes the wedge block 53 to reset. When the second gear 35 moves up and meshes with the first gear 34, the second gear 35 rotates to drive the first gear 34 to rotate, so that the connecting rod 22 rotates to a horizontal state, and then continues to move up to contact with the fixed plate 46, opens the limit plate 41, and puts a new workpiece into the U-shaped plate 24. The above operation is repeated in the same way, so that the welding hand 12 bends and welds the workpiece on the left.

[0030] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
