[0002] The blank of the gear ring is generally made of round steel rolled and welded. When the gear ring blank is seam welded, it is generally necessary to use a tool for positioning. When the traditional positioning tool is used to weld and position the gear ring blank, the displacement between the welding mechanism and the positioning tool is relatively fixed.

[0038] like Figure 1-2 As shown, the bow-shaped clamping mechanism 6 includes a lifting column 61, a slider B 62 is installed at the bottom of the lifting column 61, the slider B 62 is engaged with the outer circular ring slide rail 21, the slider B 62 is slidably connected with the double circular ring slide rail 2, and a supporting cross plate 63 is installed on the top of the lifting column 61.

[0039] The bow-shaped slider 65 inside the bow-shaped clamping mechanism 6 is slidably installed on the supporting cross plate 63 with two square through holes 64 under the action of the elastic force of the spring 66, so that the bow-shaped clamping mechanism 6 can clamp different gear ring blank bodies 5.

[0040] like Figure 1-2 As shown, the telescopic positioning mechanism 3 includes a support rod 31, which is fixedly installed above the limit assembly 41.
