[0046] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. Example 1

[0052] A welding mechanism 6, which is arranged at the top rear side of the frame 1, and is used to weld the welding seams of two groups of workpieces;

[0053] The transverse adjustment mechanism 5 and the welding mechanism 6 are connected to the transverse adjustment mechanism 5 . The transverse adjustment mechanism 5 is used to adjust the horizontal position of the welding mechanism 6 according to the position of the welding seam. Example 2

[0054] Please refer to Figure 7 As shown, the clamping mechanism 2 includes a frame 201, a threaded rod 202 and a guide rod 203. The threaded rod 202 is rotatably connected to the inside of the frame 201, and the guide rod 203 is fixedly connected to the inside of the frame 201. The two ends of the outer surface of the guide rod 203 are slidably connected with a pressure block 205 and a clamping frame 206 respectively.

A servo motor 204 is fixedly installed on the top of the frame 201, and the top of the threaded rod 202 is fixedly installed on the output end of the servo motor 204.

[0055] It can be understood by those skilled in the art that the output end of the servo motor 204 drives the threaded rod 202 to rotate, so that the pressure block 205 and the clamping frame 206 move closer to or farther away from each other. When they move closer, the workpiece to be welded is clamped, and when they move farther away, the workpiece is released from the clamping. Example 3

[0056] Please refer to Figure 5 and Figure 6As shown, the longitudinal adjustment mechanism 4 includes a mounting plate 402, and first fixed blocks 404 are welded at the four corners of the mounting plate 402.

The outer side of the mounting plate 402 is rotatably connected with a rotating member 412, and both ends of the rotating member 412 are rotatably connected with connecting arms 413, and the two groups of connecting arms 413 are rotatably connected with the first movable member 410 and the second movable member 411 respectively, and the first movable member 410 and the second movable member 411 are both welded to the frame 201.

[0057] Personnel in the technical field can understand that, by driving the first screw rod 408 to rotate through the output end of the first stepper motor 409, the second movable member 411 can slide back and forth along the surface of the connecting rod 405, and with the cooperation of the connecting arm 413 and the rotating member 412, the first movable member 410 and the second movable member 411 can be brought closer to or farther away from each other, and the spacing between the two groups of clamping mechanisms 2 connected to the first movable member 410 and the second movable member 411 can be adjusted according to the width of the workpiece, so that the two groups of clamping mechanisms 2 can clamp the two ends of one side of the workpiece, and under the action of the longitudinal adjustment mechanism 4, the two outer sides of the workpiece can be abutted against the inner walls of the front and rear clamping frames 206, and under the action of the output end of the servo motor 204, the pressure block 205 is pressed against the inside of the clamping frame 206, which is equivalent to dual clamping of the workpiece, namely longitudinal clamping and vertical clamping, thereby improving the clamping effect. Example 4

On the contrary, when the output end of the cylinder 305 is retracted, the first movable plate 306 and the second movable plate 311 both move in a direction close to the connecting plate 302. Example 5

[0061] Please refer to Figure 2 As shown, the interior of the second movable plates 311 on both sides are rotatably connected with a rotating shaft 401, and the ends of the two groups of rotating shafts 401 close to each other are welded to the mounting plate 402, and a driving motor 403 is fixedly installed on the outer side of one group of the second movable plates 311, and one end of one group of rotating shafts 401 is fixedly connected to the output end of the driving motor 403.

When the lifting frame 504 moves upward, the two sets of electromagnetic rods 508 are tilted downward toward the left side, so that the L-shaped block 601 moves to the left side. When the L-shaped block 601 moves to the welding position, the electromagnetic rods 508 are started. The L-shaped block 601 is made of iron material, so the position of the L-shaped block 601 can be fixed; and when the lifting frame 504 moves downward, the two sets of electromagnetic rods 508 are tilted downward toward the right side, so that the L-shaped block 601 moves to the right side. Similarly, when the L-shaped block 601 moves to the welding position, the electromagnetic rods 508 are also started, which changes the way of driving through tracks in real life. This method has a lower cost.

[0069] The working principle and use process of this device are as follows: First, the output end of the first stepper motor 409 drives the first screw rod 408 to rotate, so that the second movable member 411 slides back and forth along the surface of the connecting rod 405, and under the cooperation of the connecting arm 413 and the rotating member 412, the first movable member 410 and the second movable member 411 can be moved closer to or farther from each other. According to the width of the workpiece to be welded, the spacing between the two groups of clamping mechanisms 2 connected to the first movable member 410 and the second movable member 411 is adjusted, and then the two groups of workpieces to be welded are respectively placed on the inner walls of the two groups of clamping frames 206 on the left and right sides to abut against each other. Under the action of the output end of the servo motor 204, the pressure block 205 is pressed inside the clamping frame 206, which is equivalent to a double clamping of the workpiece in the longitudinal direction and the vertical direction, thereby improving the clamping effect;

[0070] After the two groups of workpieces to be welded are fixed, when the output end of the cylinder 305 is extended, the first extension member 303 is in an extended state. During the extension process, the first gear 309 is driven to rotate, so that the second gear 310 is rotated, and then the second extension member 312 is also in an extended state, and the third extension member 313 and the fourth extension member 314 are also in an extended state, so that the first movable plate 306 and the second movable plate 311 both move in a direction away from the connecting plate 302, and the movement of the first movable plate 306 and the second movable plate 311 is a horizontal movement, so that the welding surfaces of the two groups of workpieces in the clamping state are fitted together;

[0071] Then, the output end of the second stepper motor 505 drives the second screw rod 502 to rotate, so that the lifting frame 504 moves up and down, so that the two sets of electromagnetic rods 508 are tilted, and then the L-shaped block 601 slides downward along the electromagnetic rods 508. When the L-shaped block 601 moves to the welding position, the electromagnetic rods 508 are started. The L-shaped block 601 is made of iron material, so the position of the L-shaped block 601 can be fixed;

[0072] The output end of the electric lifting rod 604 drives the laser welding head 611 to move downward to contact the top side of the welding surface of the two groups of workpieces. Under the action of the output end of the third stepper motor 615, the laser welding head 611 reciprocates along the top side of the welding surface to achieve welding, and the two groups of workpieces are welded into a whole. Then, the clamping mechanism 2 on the right is released, and the telescopic mechanism 3 on the right is in a contracted state. Then, the output end of the driving motor 403 drives one of the groups of rotating shafts 401 to rotate, so that the whole workpiece is turned over. Repeat the above operation, so that the laser welding head 611 welds the remaining side surfaces of the welding surface;

[0073] After welding is completed, the driving gear 603 is driven to rotate through the output end of the transmission motor 602, so that the driving gear 603 and the electric lifting rod 604 keep rotating as a whole, driving the lifting block 606 to rotate, and then the knocking head 612 rotates and faces the front side, and the horizontal position of the L-shaped block 601 is changed through the lateral adjustment mechanism 5, so that the L-shaped block 601 moves to the top of the right workpiece, and the output end of the electric lifting rod 604 drives the knocking head 612 to move downward, so that the knocking head 612 hammers the workpiece on the right side, and observes the welding quality of the workpiece. It is convenient and fast, and the structure is simple, which meets the needs of the staff.
