There are two sets of guide wheel mechanisms 2, and a horizontal cylinder 4 for driving the two sets of transverse slides 7 to open or clamp is connected between the two sets of transverse slides 7; the guide wheel mechanism 2 includes a guide wheel body 21 and a rotating shaft 22 for installing the guide wheel body 21 on the guide wheel bracket 8, the two sets of guide wheel bodies 21 are distributed in a flared shape, and the inner outer chamfers are limited to the two sides of the spiral rib plate, and the outer outer chamfers are abutted against the inner wall of the cylinder; a welding gun adjustment mechanism 9 is installed on one set of transverse slides 7, and a welding gun body 97 for welding the spiral rib plate in the cylinder is installed on the welding gun adjustment mechanism 9.

[0025] A guide sprocket 11 for guiding and supporting the bottom side of the window opener chain 10 is also provided at the corner of the crossbeam 14, so as to achieve stable steering of the window opener chain 10 and avoid jamming of the window opener chain 10 during movement.

[0026] In this embodiment, a spiral rib welding tracking mechanism in a cylinder also includes a displacement sensor 12 installed on the transverse slide 7, and the pull rod 13 end of the displacement sensor 12 is installed on the horizontal slide 3, so that the electrical control system determines whether the position of the spiral rib is offset through the pull rod 13 position signal of the pull rod 13 type linear displacement sensor 12, and drives the auxiliary roller frame of the automatic welding machine to move according to the offset data obtained by calculation processing, so as to realize the movement of the cylinder during welding, and also ensure that the rib position is always adjusted to the vertical position between the two sets of guide wheel mechanisms 2.

[0027] The driving end of the vertical cylinder 5 and the top end of the longitudinal slide 6 are fixedly connected to the two ends of the window opener chain 10 by screws.
