[0030] A welding tool for steel component production, comprising:

[0031] A top plate 110, a cylinder 120, a synchronization rod 130 and two holding members 140;

[0032] The cylinder 120 is fixed on the top of the top plate 110, and its driving rod passes through the top plate 110;

[0038] Two holding arms are symmetrically arranged at the bottom of the top plate 110; the holding arms include a fixed short arm 143 fixed to the bottom of the top plate 110, a movable arm 144 hinged to the lower end of the fixed short arm 143, a holding support arm 145 hinged to the lower end of the movable arm 144, and an arc-shaped holding plate 145 fixed to the inner side of the holding support arm 145;

[0039] The other end of the driving connecting rod 146 is hinged to the movable arm 144 .

[0040] Figure 4 As shown; in this embodiment, the side wall of the movable arm 144 is provided with a through hole 145a, and a coaxial rod 146 is arranged through the through hole 145a of the two movable arms 144 on the same side; the coaxial rod 146 is arranged on the two movable arms 144 on the same side, and the two clamping members 140 can further maintain synchronous operation during the clamping operation, thereby improving the coaxiality of the two circular columns during welding.

[0043] The working principle of a welding tool for steel component production provided by the embodiment of the utility model is as follows:
