Description

Technical Field

[0001] The utility model relates to a stud assembly fixture, belonging to the technical field of stud and nut assembly jigs. Background Art

[0002] In the production of some products, the assembly process of studs and nuts is involved, especially the assembly of some special-shaped nuts and studs. If manual assembly is used, the production efficiency is low. Therefore, a corresponding assembly mechanism is needed to replace manual operation. In order to ensure the stability of the studs during assembly, a stud fixing device is needed to fix the studs. In addition, Figure 2 As shown, the stud 4 is provided with a radially protruding protrusion 11, the special-shaped nut 12 is provided with a retaining ring 13 for preventing the nut from retreating, and the retaining ring 13 is provided with a feeler 14. When the special-shaped nut 12 is screwed to a certain height, the feeler 14 will block the protrusion 11. If the special-shaped nut 12 is to be screwed further, the feeler 14 must be lifted up and staggered. Ordinary stud assembly jigs are difficult to meet these assembly requirements.
