[0036] Specifically, when the first deflection rod 402 and the second deflection rod 405 are in a horizontal state, the mechanism is in a dead point state. At this time, the rotation of the first deflection rod 402 will drive the first rotating shaft 401 to deflect, so that the magnetic wedge block 907 is in a horizontal state. Due to the presence of the wedge-shaped electromagnet 906, the end of the wedge-shaped electromagnet 906 is sharply set, which can avoid the dead point state.

[0037] In addition, when the first deflection rod 402 deflects downward, the wedge-shaped electromagnet 906 at the bottom is turned on to attract the magnetic wedge block 907 to deflect downward, and when the first deflection rod 402 deflects upward, the wedge-shaped electromagnet 906 at the top is turned on to attract the magnetic wedge block 907 to deflect upward, so as to accelerate the avoidance of the dead point and increase the smoothness of the deflection of the first deflection rod 402 and the second deflection rod 405.

[0038] During the implementation of the present invention, the hollow seat 1 is first moved to the position where welding is required by rotating the wheel mechanism 2. At this time, the deflection adjustment rod mechanism 4 is turned on, and the dead point sliding avoidance mechanism 9 can prevent the deflection adjustment rod mechanism 4 from being stuck at the dead point, so that the installation frame 5 is in contact with the ground. At this time, the workpiece that needs to be butt-welded can be moved by the side roller mechanism 6, and further moving the workpiece can make the workpiece move to the rotating support roller 7. At this time, the positioning roller mechanism 8 is turned on to clamp and fix the workpiece. At this time, the deflection adjustment rod mechanism 4 is turned on again to deflect the installation frame 5, thereby driving the workpiece to align. At this time, the positioning roller mechanism 8 can adjust the workpiece deflection displacement to achieve fine alignment. At this time, the displacement welding mechanism 3 is turned on to weld the workpiece.

[0039] The present invention can perform welding processing on HVACs of different sizes by setting a displacement welding mechanism 3, can lift the HVAC on the installation frame 5 by means of a deflection adjustment rod mechanism 4, and can align and weld two workpieces at the same time, can avoid the deflection adjustment rod mechanism 4 from being at a dead point by means of a dead point avoidance mechanism 9, can clamp the workpiece by means of a positioning roller mechanism 8, and can shift and displace the workpiece at the same time, so as to perform welding at different circumferential positions of the workpiece, thereby improving the efficiency of HVAC installation welding.
