Abstract

The invention relates to a locating pin for a welding fixture. The locating pin comprises a locating pin main part and an auxiliary part. One end of the locating pin main part is of a frustum-shaped structure, and the other end of the locating pin main part is provided with an external thread. The auxiliary part is fixed to the middle upper end of the locating pin main part. The lower portion of the auxiliary part and a contact segment of the locating pin main part are of a cylindrical structure. The upper end of the auxiliary part is of a frustum-shaped structure. An annular protrusion is arranged on the outer surface of the middle end of the cylindrical structure located on the auxiliary part. The locating pin for the welding fixture is simple in structure and ingenious in design; in the process of being cooperatively used with the welding fixture, through the special structural design of the locating pin main part and the special structural design of the auxiliary part, the locating pin has an outstanding fixing effect, and is more precise in location and suitable for the requirements of large-scale industrial production.

Description

technical field [0001] The invention relates to the field of welding fixture manufacturing, in particular to a positioning pin of a welding fixture. Background technique [0002] At present, the main reasons for the failure of the nut fastening method in the production process are: the spring washer is not used according to the technical requirements when the positioning pin is assembled; the assembly torque of the positioning pin is not standardized. When it is too large, it will cause overload damage to the thread. Therefore, in order to prevent the occurrence of the positioning failure mode of the positioning pin, we must proceed from the design of the positioning mechanism and the daily management of the positioning pin. Contents of the invention [0003] The problem to be solved by the present invention is to provide a positioning pin for a welding fixture that is accurate in positioning, long in use and easy to manufacture. [0004] In order to solve the problems e...
