Clamping grooves 3112 are provided on both side walls of the mounting groove 3111. When the inner seat 312 moves into the outer seat 311, the clamping grooves 3112 can drive the two groups of clamping members 314 to move in a direction close to each other to clamp the reinforcing ribs, thereby ensuring the stability of the reinforcing ribs during the welding process.

In this state, the radial reinforcing rib to be welded is forcefully clamped into the clamping groove 3121 of the inner seat 312, and the radial reinforcing rib can remain stable under the clamping action of the two groups of clamping members 314, and then the clamping seat 31 is driven by the pressing electric cylinder 32 to move as a whole towards the steel template, so that the radial reinforcing rib can be fitted on the outer wall of the steel template.
