[0014] The present invention is described in detail below in conjunction with specific embodiments:
[0015] like Figures 1 to 3 The seat frame shaping and assembly welding tool shown in the figure includes a carrier plate 1, an end stop seat 2, a round table 3, a positioning pin 31, a positioning clamp 4 and a clamping mechanism.

The positioning clamps 4 are provided with positioning grooves. The positioning grooves of several positioning clamps 4 are arranged corresponding to the direction of the seat frame.
[0016] The clamping mechanism is composed of a telescopic cylinder 5, a driving rod 51, a first connecting plate 61, a pressure head 63, a guide limit sleeve 7, a regular polygon limit guide block 8, a first connecting rod 81, a second connecting rod 82 and a collar 83. The cylinder body of the telescopic cylinder 5 is fixedly mounted on the carrier plate 1, the guide limit sleeve 7 is fixedly mounted on the top of the cylinder body of the telescopic cylinder 5, the driving rod 51 is fixedly mounted on the piston rod of the telescopic cylinder 5, the driving rod 51 is slidably mounted in the first through hole of the guide limit sleeve 7, the guide limit sleeve 7 is further provided with a regular polygon limit hole 71 connected to the first through hole, the regular polygon limit hole 71 is matched with the regular polygon limit guide block 8, and the driving rod 51 is provided with a second through hole which passes through from front to back. Hole 50, the first connecting rod 81 and the second connecting rod 82 are coaxially fixedly mounted on the upper and lower ends of the regular polygonal limiting guide block 8, the second connecting rod 82 is slidably mounted on the top of the driving rod 51, and the lower end of the second connecting rod 82 is placed in the second through hole 50, the collar 83 is fixedly mounted on the bottom of the second connecting rod 82, and the collar 83 can move up and down and rotate freely horizontally in the second through hole 50, the regular polygonal limiting guide block 8 can be slidably mounted in the regular polygonal limiting hole 71, the first connecting plate 61 is fixedly mounted on the top of the first connecting rod 81, the pressure head 63 is fixedly mounted on the bottom surface of the outer end of the first connecting plate 61, and the regular polygonal limiting guide block 8 is set to an octagonal structure to meet the use requirements of multiple angle positions.
[0017] The bottom surface of the regular polygonal limiting guide block 8 is set to an oblique angle structure, so that the regular polygonal limiting guide block 8 can be slidably embedded in the regular polygonal limiting hole 71 of the guide limiting sleeve 7.
[0018] The second connecting plate 62 is fixedly installed on the outer end of the first connecting plate 61, and the pressure head 63 is fixedly installed on the bottom surface of the outer end of the second connecting plate 62. The second connecting plate 62 and the first connecting plate 61 are adjusted in position through the oblong holes set in the length direction to solve the problem that the installation position of the pressure head 63 and the first connecting plate 61 cannot be adjusted.
[0019] Anti-collision rubber rings are fixedly installed on the upper and lower end surfaces of the ring 83, and the anti-collision rubber rings extend 0.6 cm beyond the upper and lower end surfaces of the ring 83 to avoid rigid collision between the upper and lower end surfaces of the ring 83 and the upper and lower end surfaces of the second through hole 50, thereby avoiding the problem of the ring 83 being loosened due to vibration caused by long-term rigid impact.
[0020] Before the two-section seat frame is clamped and positioned, the operator pulls up the combination of the first connecting plate 61 and the regular polygon limit guide block 8, so that the regular polygon limit guide block 8 disengages from the regular polygon limit hole 71, and rotates the first connecting plate 61 so that the pressure head 63 does not interfere with the clamping of the two-section seat frame. The two-section seat frame is placed in the positioning groove of the positioning clamp 4, and the two sections of the seat frame are positioned respectively by the end limit seat 2 and the positioning pin 31.
