[0035] In this embodiment, as shown in the attached Figure 6 - Attachment Fig.10As shown, the bilateral interval welding assembly includes a guide frame 29 fixedly arranged on the upper surface of the welding platform 1; the inner wall of the guide frame 29 is fixedly connected with a slide bar 30, and the outer wall of the slide bar 30 is slidably connected with a guide sleeve 31, the guide sleeve 31 is slidably connected with the guide frame 29, a push cylinder 32 is installed on one side of the guide sleeve 31, the push cylinder 32 is fixedly connected with the guide frame 29, and the output end of the push cylinder 32 is fixedly connected with the guide sleeve 31; a concave bar 33 is fixedly installed on the upper surface of the guide sleeve 31, and welding guns 34 are fixedly installed at both ends of the concave bar 33. The inner wall of the guide frame 29 and the outer wall of the guide sleeve 31 are both smooth surfaces, and two welding guns 34 are symmetrically arranged about the slide bar 30.

[0036] The working principle of the flexible welding workstation for the sheet heat sink for transformer of the present invention is as follows: First, when the present invention is installed, the welding platform 1 is first fixed to the welding frame by inserting bolts according to the holes on the welding platform 1. The welding platform 1 supports the bracket 35, and the bracket 35 supports the sliding frame 22, thereby increasing the stability of the sliding frame 22. The heat dissipation workpiece 20 is inserted into the inner wall of the positioning frame 21, and the positioning frame 21 positions and places the heat dissipation workpiece 20, and at the same time, multiple transformer heat dissipation fins 16 are respectively inserted into the inner walls of multiple adjustment frames 5.

[0037] Secondly, when the present invention adjusts the interval welding, the adjustment value of the interval welding is set on the controller 36, and the controller 36 is used to start multiple adjustment motors 7 to achieve driving, and the multiple adjustment motors 7 respectively drive the multiple adjustment screws 8 to rotate, and the adjustment screws 8 drive the articulated sleeve 9 to move downward under the action of the thread transmission force, and the articulated sleeve 9 drives the two connecting shafts 10 to move downward, and the connecting shaft 10 drives the top of the sleeve rod 11 to move downward, and the bottom end of the connecting shaft 10 drives the linkage shaft 12 to move right, and the other linkage shaft 12 moves left. The linkage shaft 12 drives the interval slot plate 13 to move right, and the interval slot plate 13 drives the L-shaped slide 17 to move right, and the L-shaped slide 17 slides on the sleeve block 4, and at the same time, the L-shaped slide 17 slides along the inner wall of the sliding sleeve block 18, and the sleeve block 4 supports the pillar 19, and the pillar 19 supports the sliding sleeve block 18, increasing the stability of the sliding sleeve block 18.

[0038] The distance between the two spacing slot plates 13 on both sides of the adjustment frame 5 becomes larger, and the other spacing slot plate 13 drives the sensing block 15 away from the spacing distance sensor 14. The spacing distance sensor 14 realizes distance sensing for the sensing block 15. When the distance value sensed by the spacing distance sensor 14 is half of the adjustment value of the spacing welding set on the controller 36, the controller 36 is used to turn off multiple adjustment motors 7, so that the spacing distance on both sides of multiple transformer cooling fins 16 can be accurately adjusted.

[0039] Then, when the present invention performs positioning adjustment and tightening, the reduction motor 24 is started through the controller 36, and the reduction motor 24 drives the linkage screw 23 to rotate. The linkage screw 23 rotates inside the sliding frame 22, and at the same time, the linkage screw 23 drives the two threaded sleeves 25 to approach each other under the action of the thread transmission force, so that the threaded sleeve 25 drives the limit support plate 26 to move left, and the other limit support plate 26 moves right. The limiting support plate 26 will drive the positioning distance sensor 27 to approach the positioning sensing block 28, so that the limiting support plate 26 drives the rightmost spacing slot plate 13 to move left, and the other limiting support plate 26 drives the leftmost spacing slot plate 13 to move right, and the rightmost spacing slot plate 13 drives the linkage shaft 12 to move left, and the linkage shaft 12 drives the sleeve rod 11 to move left, and the sleeve rod 11 drives the connecting shaft 10 to move left, and the connecting shaft 10 drives the hinged sleeve block 9 to move left, and the hinged sleeve block 9 drives the sleeve frame 6 to move left, and the sleeve frame 6 drives the sleeve block 4 to move left, and the sleeve block 4 slides to the left along the outer wall of the support rod 3, and the sleeve frame 6 drives the adjustment frame 5 to slide to the left at the same time, so that the adjustment frame 5 drives the transformer cooling fins 16 to move left, and the transformer cooling fins 16 slide along the upper surface of the heat dissipation workpiece 20, so that the two adjacent spacing slot plates 13 are all fitted together.

[0040] The distance sensing of the positioning sensing block 28 is performed through the positioning distance sensor 27. When the distance value sensed by the positioning distance sensor 27 is the same as the distance value set by the controller 36, the two limit support plates 26 tighten the positioning adjustment of the multiple transformer cooling fins 16 within the specified range, so that the multiple transformer cooling fins 16 can be adjusted according to the interval welding distance, and welding can be carried out after the adjustment is completed.

[0041] Finally, when the present invention performs bilateral interval welding, the controller 36 is used to start the pushing electric cylinder 32, and the pushing electric cylinder 32 pushes the guide sleeve 31 to move left, and the guide sleeve 31 slides left along the outer wall of the slide rod 30, and the guide sleeve 31 drives the concave bar 33 to move left and slide, and the concave bar 33 causes the two welding guns 34 to move left and slide, and then the two welding guns 34 are opened, so that the welding gun 34 can weld the connection between the heat dissipation workpiece 20 and the left side of the transformer heat dissipation fin 16, and the other welding gun 34 can weld the connection between the heat dissipation workpiece 20 and the right side of the transformer heat dissipation fin 16, and multiple transformer heat dissipation fins 16 and the heat dissipation workpiece 20 are welded at bilateral intervals.
