[0005] Furthermore, the base plate is equipped with V-blocks, auxiliary support seats, and flat keys via bolts or screws.

[0006] Furthermore, the first baffle, the second baffle, and the pad are respectively connected to the V-block by bolts.

[0007] Furthermore, the lead screw sleeve is connected to the auxiliary support seat via an internal hex screw.

[0008] The beneficial effects of this utility model are: 1. It can quickly position and align, reducing the labor intensity and production time of operators, and saving the cost of tooling for bridge housing processing; 2. It can be universal, saving the cost of fixture investment and the time spent changing fixtures; 3. The tooling structure is simple and easy to change and operate. Attached Figure Description
