The first fixed plate 102 is located inside the protective shell 7 and is transmission-connected to a clamping rotating gear set 11 at a position close to the transmission main gear set 802. The first fixed plate 102 is transmission-connected to the servo motor 801 on the right side and is located inside the protective shell 7 with a clamping transmission shaft 12.

The second fixed plate 103 is fixedly connected to one side of the top of the mounting plate 101.

[0040] Among them, the fourth fixed plate 105 is fixedly connected to both sides of the mounting plate 101 and away from the first fixed plate 102, and a transmission gear assembly 15 is movably connected to an adjacent side of the fourth fixed plate 105 and near the top position.

The fifth fixed plate 106 is fixedly connected to the mounting plate 101 and away from one side of the servo motor 801.

[0042] Among them, the multi-structure clamping head 10 is fixedly connected to a limited moving rod 1001 at one side close to the rotation limit box 9, and the limited moving rod 1001 is sleeved on both sides of the surface of the clamping gear set 16.

[0043] Working principle of the present invention: First, when clamping and welding the splicing parts, place the splicing parts to be welded adjacent to one side of the multi-structure clamping head 10. Then, turn on the servo motor 801 on the right side of the first fixing plate 102, so that the servo motor 801 drives the clamping transmission shaft 12 and the clamping screw 13 fixedly connected thereto to rotate under the support of the second fixing plate 103 and the fifth fixing plate 106. Then, the rotation of the clamping screw 13 drives the transmission gear assembly 15 to rotate. Then, the rotation of the transmission gear assembly 15 causes the gears on its surface to drive the moving screw sleeve 14 on the surface of the clamping rotation gear set 11. At this time, the moving screw sleeve 14 slides on the surface of the clamping rotation gear set 11. Then, the sliding of the moving screw sleeve 14 drives the clamping gear set 16. At this time, the clamping gear set 16 rotates under the limitation of the rotation limiting box 9. Then, the clamping gear set 16 rotates to drive the multi-structure clamping head 10 on its surface. At this time, the multi-structure clamping heads 10 approach each other to clamp the splicing parts. At this time, the telescopic clamping head 1704 is squeezed by the clamped splicing parts. Then, the telescopic clamping head 1704 pushes the rubber sealing plug 1705 to squeeze the air inside the air pressure chamber 1706. At this time, the air in the air pressure chamber 1706 enters the inside of the air collection chamber 1702 through the communication hole 1707. Then, the air inside the air collection chamber 1702 enters the inside of the remaining cylindrical air pipelines 1703 through the communication hole 1707, and pushes the telescopic clamping head 1704 with a smaller squeezing force to fix the splicing parts. At the same time, due to the limitation of the material of the telescopic clamping head 1704 itself, the surface of the splicing parts is protected from being damaged due to clamping. Then, due to the flexible change characteristics of the telescopic clamping head 1704 on one side of the rectangular air chamber 1701, various special-shaped splicing parts can be clamped and fixed by the multi-structure clamping head 10 and the adjusting clamp assembly 17;

[0044] Then, after the intelligent positioning welding member 6 positions and welds the splicing parts through the welding slider 5, the positioning frame 4 and the electric sliding member 3, turn on the servo motor 801 on the left side of the first fixing plate 102 at this time, so that the main transmission gear set 802 rotates and drives the clamping rotation gear set 11 to rotate. Then, the rotation of the clamping rotation gear set 11 causes the clamping rotation gear set 11 to drive the rotation limiting box 9 to rotate on the surface of the fifth fixing plate 106. At this time, the moving screw sleeve 14 is restricted by the transmission gear assembly 15 and does not rotate with the clamping rotation gear set 11. Then, the rotation of the rotation limiting box 9 drives the clamping gear set 16 inside it and the splicing parts clamped by the multi-structure clamping head 10 to rotate together. At this time, start the intelligent positioning welding member 6, the positioning frame 4 and the electric sliding member 3 to weld the rotated splicing parts.

[0045] Finally: The above is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
