[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the closed dragging assembly includes multiple positioning seats 6 mounted on the positioning assembly. A fitting seat 7 is attached to one side of the positioning seat 6. An operating rod 8 is slidably connected inside the fitting seat 7. A reset groove is opened inside the fitting seat 7 on the outside of the operating rod 8. A reset plate 9 is slidably connected inside the reset groove. The reset plate 9 is rotatably connected to the operating rod 8. A first spring 10 is installed between the two ends of one side of the reset plate 9 and the reset groove. A retraction groove is opened on the side of the fitting seat 7 near the positioning seat 6. An extension groove is opened on the other side of the fitting seat 7. A torsion plate 11 is installed at one end of the operating rod 8 that extends into the extension groove. First, the operator can bring the fitting seat 7 on the corresponding clamp 5 close to the positioning seat 6 according to the thickness of different cables. Then, the operator pinches the torsion plate 11 and squeezes the operating rod 8 downward. The operating rod 8 can drive the locking block 15 to move down. The reset plate 9 squeezes the two sets of first springs 10 and slides into the installation groove through the docking groove.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the pressing assembly includes a mating groove on one side of the positioning seat 6, a locking block 15 installed on the other end of the operating lever 8, the locking block 15 being slidably connected to the mating groove, a positioning block 16 installed on the other side of the locking block 15, an installation groove inside the positioning seat 6 located on one side of the mating groove, a second spring 17 installed at both ends of one side of the inner wall of the installation groove, a fixed plate 18 installed at the other end of the second spring 17, a movable plate 19 rotatably connected inside the fixed plate 18, a positioning groove on one side of the movable plate 19, the positioning groove being slidably connected to the positioning block 16, and the two sides of the inner wall of the installation groove...

Then, continue to press down, the fixed plate 18 presses the two sets of second springs 17 to retract, and pushes the block 15 completely into the installation groove. Then twist the operating rod 8, so that the positioning block 16 and the positioning groove drive the movable plate 19 to rotate together. After the block 15 is rotated to the longitudinal direction, the operating rod 8 can be released, and the block 15 will spring back and lock into the two sets of slots to complete the positioning of the clamping plate 5. Conversely, when disassembly and separation are required, simply press down the operating rod 8 again to rotate the block 15 to the lateral direction, and it can be pulled out from the docking groove for separation.

Furthermore, after locking, the snap-pull groove can be engaged with the synchronization groove 14 and the synchronization block to drive the closing plate 12 to slide inside the closing groove, so that the closing plate 12 covers the extension groove, causing the magnetic block 13 to attract the iron block, and covering the twist plate 11 to prevent accidental contact that could cause the clamp 5 to loosen.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the positioning assembly includes a fixed frame mounted on one side of the positioning frame 4, an adjusting cylinder 20 mounted on one side of the fixed frame, a first threaded rod 21 rotatably connected to the inner side of the adjusting cylinder 20, the threads at both ends of the first threaded rod 21 being opposite, the first threaded rod 21 being threadedly connected to the positioning seat 6, a first motor mounted on one side of the fixed frame, the drive end of the first motor extending to the inner side of the adjusting cylinder 20 and fixedly connected to one end of the first threaded rod 21, the positioning seat 6 being slidably connected to the inner side of the adjusting cylinder 20, further, starting the first motor can drive the first threaded rod 21 to rotate, causing the two sets of positioning seats 6 to slide inside the adjusting cylinder 20, causing the two sets of clamping plates 5 to adhere to the outer wall of the cable, allowing it to stably adhere to the welding point.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the position adjustment mechanism includes a second cylinder 25 installed at one end of the top of the base 1. A connecting frame 22 is installed at the output end of the second cylinder 25. A connecting groove is opened on one side of the connecting frame 22.

A first cylinder 24 is installed at one end of the connecting block. The output end of the first cylinder 24 is fixedly connected to one side of the third motor 2. Furthermore, after the cable is attached, the second motor can be started to drive the second threaded rod 23 to rotate, so that the connecting block moves inside the connecting groove, thereby changing the left and right positions of the first cylinder 24 and the welding torch 3. Then, starting the first cylinder 24 can change the front and back position of the welding torch 3. Starting the third motor 2 can adjust the welding angle of the welding torch 3. Starting the second cylinder 25 can change the height of the welding torch 3.

[0027] The implementation principle of the copper busbar welding device for connecting the return cable and the rail in this application embodiment is as follows: The operator can position the corresponding fitting seat 7 on the clamping plate 5 close to the positioning seat 6 according to the thickness of the cable. Then, the operator pinches the twisting plate 11 and presses down on the operating rod 8. The operating rod 8 can drive the locking block 15 to move downwards. The reset plate 9 then presses down on the two sets of first springs 10, which slide into the installation groove through the docking groove. Continuing to press downwards, the fixing plate 18 presses down on the two sets of second springs 17 to retract, pushing the locking block 15 completely into the installation groove. After twisting the operating rod 8, the positioning block 16, in conjunction with the positioning groove, drives the movable plate 19 to rotate together, rotating the locking block 15 to the longitudinal position. At this point, the operating rod 8 can be released, allowing the locking block 15 to spring back and lock into the two sets of slots, completing the positioning of the clamping plate 5. Conversely, when disassembly and separation are required, simply press down on the operating rod 8 again to rotate the locking block 15 to the transverse position, allowing it to be removed from the docking groove. The connection slot is pulled out for separation. After locking, the latching slot can be engaged with the synchronous slot 14 and synchronous block to drive the closing plate 12 to slide inside the closing slot, so that the closing plate 12 covers the extension slot, causing the magnetic block 13 to attract the iron block, covering the torsion plate 11 to prevent accidental contact that could cause the clamping plate 5 to loosen. Starting the first motor can drive the first threaded rod 21 to rotate, so that the two sets of positioning seats 6 slide inside the adjusting cylinder 20, causing the two sets of clamping plates 5 to adhere to the outer wall of the cable, so that they are stably attached to the welding point. After the cable is attached, the second motor can be started to drive the second threaded rod 23 to rotate, so that the connecting block moves inside the connecting slot, causing the first cylinder 24 and the welding gun 3 to change the position in the left and right directions. Then, starting the first cylinder 24 can change the front and back position of the welding gun 3. Then, starting the third motor 2 can adjust the welding angle of the welding gun 3. Starting the second cylinder 25 can change the height of the welding gun 3.
