[0012] like Figure 1-3The welding positioning device for boiler pipe silencer production shown includes a mounting plate 1 and a positioning assembly mounted on the mounting plate 1. The mounting plate 1 is U-shaped, and bolts are threaded onto the bottom surface of the mounting plate 1. A support rod 2 is fixedly mounted on the upper surface of the mounting plate 1. The positioning assembly includes a center rod 11, a lifting block 4, and a movable ball 5. The center rod 11 is embedded in the center of the support rod 2 and is a threaded rod. A threaded groove is opened at the center of the support rod 2. The lifting block 4 is fixedly mounted on the top of the center rod 11. A threaded tube 12 is provided at the top of the support rod 2. The threaded tube 12 is threaded onto the outside of the center rod 11 and is connected to the top of the support rod 2 through a bearing. A striped ring 3 is fixedly mounted on the outer wall of the threaded tube 12.
[0013] The top surface of the lifting block 4 has an arc-shaped groove, and the movable ball 5 is embedded in the groove of the lifting block 4. Multiple fixing blocks 7 are fixedly installed on the top edge of the lifting block 4 in a circular array. One outer wall of the multiple fixing blocks 7 is tangent to the outer wall of the movable ball 5. The outer wall of the fixing blocks 7 has a threaded hole, and a bolt is installed in the threaded hole of the fixing block 7. A connecting rod 6 is fixedly installed on the outer wall of the movable ball 5, and a fastening ring is fixedly installed at the end of the connecting rod 6.
[0014] A guide rod 8 is fixedly installed on the outer wall of the lifting block 4, and a guide block 9 is fixedly installed on the top of the outer wall of the support rod 2. The outer wall of the guide block 9 is slotted, and the guide rod 8 is embedded in the slot of the guide block 9.
