Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of assembly fixture, especially stopper assembly fixture. BACKGROUND

[0002] The stopper is a mechanical device, which is mainly used for limiting the movement of an object. The stopper can accurately define the limit position of the movement of a mechanical component. For example, during the extension of a lifting arm of a crane, the stopper installed on the lifting arm can prevent the lifting arm from overextending, thereby avoiding safety accidents. When the lifting arm extends to the set maximum angle, the stopper contacts the corresponding component on the main structure of the crane, thereby preventing the lifting arm from continuing to extend. The stopper assembly is a process of combining various parts of the stopper together so that the stopper can normally play the function of limiting movement.

[0003] In the prior art, when assembling the stopper, the worker needs to manually place each part of the stopper on the positioning device of the fixture. For the stopper shell with a specific shape and hole position, the worker needs to rely on experience and naked eye observation to align the mounting hole of the shell with the positioning pin on the fixture, and then fix the shell by manually operating the clamping device (such as rotating the clamping handle). In this process, the operation proficiency and attention of the worker have a great influence on the accuracy and efficiency of the clamping. These frequent adjustments consume a lot of time, further reducing the production efficiency. UTILITY MODEL CONTENT
