Abstract

The invention relates to a fastening, indexing and rotating mechanism for a central pipe. The fastening, indexing and rotating mechanism comprises a base, a motor with a brake, an inner expanding rod, a cylinder, an inner expanding head, an indexing shaft, a conical expanding core and an indexing head, wherein both the motor and the cylinder are fixedly connected with the base, the middle of the indexing shaft is mounted in a central mounting hole of the indexing head in a penetrating manner, the right end of the indexing shaft is connected with the inner expanding head, a central through hole is axially formed in the indexing shaft, the inner expanding rod is connected with the conical expanding core at the right side of the inner expanding head after penetrating through the central through hole and the inner expanding head, a claw part cooperatively coordinating with the conical expanding core is arranged at the right end of the inner expanding head, the cylinder is arranged on the outer side at the left end of the inner expanding rod, the piston rod end of the cylinder is in axial transmission connection with the left end of the inner expanding rod, and the end, extending out of the indexing head, of the left end of the indexing shaft is in transmission connection with the motor.

Description

technical field [0001] The invention relates to an automatic welding machine, in particular to a central tube fastening indexing and rotating mechanism. Background technique [0002] The metal five-star base of the office chair includes a central tube and five legs set around the main body. The five tripods are welded to the central tube. According to the current technical means, each tripod is positioned by the positioning tool and the main body in turn, and then manually welded. Its disadvantages are: low efficiency, high labor cost, and it is not suitable for mass production of five-star feet. Contents of the invention [0003] The object of the present invention is to provide a central tube fastening indexing and rotating mechanism in order to avoid the disadvantages in the background technology. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a central tube fastening indexing and rotating mechanism, inc...
