Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spring press fitting, specifically relates to a spring press fitting mechanism. BACKGROUND

[0002] In the field of mechanical assembly, the clamping spring plays an important role as a key elastic fastening part. In traditional mechanical structures, shafts and holes are often axially positioned and fastened, and the clamping spring becomes an ideal choice due to its good elasticity and adaptability. However, the installation and use of the clamping spring face many problems. In the early stage, manual operation was mainly relied on. Because the clamping spring is small in size and large in elasticity, it is not only low in installation efficiency and high in labor intensity, but also prone to safety hazards such as clamping spring ejection. Moreover, simple semi-automatic installation equipment also has defects such as inaccurate positioning and uncontrollable pressing force, resulting in uneven clamping spring installation quality and affecting the performance of the entire mechanical assembly. Therefore, it is particularly urgent to develop more efficient, accurate and safe clamping spring installation related technology and equipment.

[0003] The traditional clamping spring installation method is mainly manual installation of the clamping spring. The operator uses the clamping spring pliers to open the clamping spring and put it into the corresponding position. Because the clamping spring itself is large in elasticity and small in size, and the clamping spring pliers are not provided with a limiting mechanism for the clamping spring pair, the clamping spring is easily ejected and hurt due to careless operation, which has a great safety hazard.
