The tooling assembly is used for positioning and assembling workpieces. Preferably, a clamping tooling structure with a relatively simple structure is adopted. On the one hand, it is convenient to operate and disassemble and assemble, and on the other hand, it has strong applicability and can be adapted to the clamping and positioning of workpieces of various specifications.

[0013] Preferably, the sandblasting tube comprises a mounting end and a plurality of unit tube sections assembled end to end in a vertical direction, and a cover assembled at the port of the bottommost unit tube section, and a sandblasting head is provided at the bottom of the outer wall of the plurality of unit tube sections. The sandblasting tube is composed of a mounting end, a cover and a plurality of unit tube sections. Preferably, the operator can adjust the length of the entire sandblasting tube by setting the specific number of unit tube sections, which further improves the flexibility of use.

[0014] The beneficial effects of the utility model are:

[0015] The technical solution of the utility model is to provide a tooling assembly driven by a reduction motor, and cooperate with a plurality of sandblasting tubes distributed in a circular array about the straight line where the axis of the output end of the reduction motor is located. During the sandblasting operation, the operator only needs to hang the workpiece to be processed in the operation box through the tooling assembly.
