Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, and more specifically to a positioning tooling for a welding machine. Background Art

[0002] Four-column steel tube towers have been widely used in transmission lines, and there are many cross nodes on the flanges of four-column steel tube towers. In order to achieve the interchangeability of tower parts, the welding size and angle requirements of each node are very strict. Therefore, the four-column steel tube tower flange cross nodes are often positioned by tooling during welding.

[0003] After searching, the utility model patent with announcement number CN215999342U discloses a positioning tool for a cross group welding machine, including: a base, two first fixed seats with adjustable positions are symmetrically arranged on both sides of the top surface of the base, each first fixed seat is fixedly provided with a first fixed chuck, and the axes of the two first fixed chucks are in the same straight line; a rotating seat, which is rotatably connected to the center of the top of the base, and two second fixed seats with adjustable positions are arranged on the top surface of the rotating seat, each second fixed seat is fixedly provided with a second fixed chuck, the axes of the two second fixed chucks are in the same straight line, and the axis of the first fixed chuck is in the same plane as the axis of the second fixed chuck. Thereby, the patent increases the adjustment accuracy of the angles of the two groups of fixed structures by adding an adjusting screw structure, and at the same time increases the slide rail and the adjusting screw, increases the lateral adjustment accuracy and size of the fixed structure, and increases the accuracy and reliability of the tooling.

[0004] However, the above patents still have the following shortcomings: the adjusting screw and lead screw are directly exposed to the outside, and splashing welding slag impurities are easy to appear during welding. When the welding slag adheres to the screw and lead screw, it affects their adjustment of the first fixed seat and the rotating seat; and it is not convenient to deal with the impurities and odor generated during welding, which affects the surrounding environment. For this reason, we propose a welding machine positioning tool. Utility Model Content
