Abstract

The invention belongs to the technical field of clamping tools, and relates to a high precision self-centering external contracting type tensioning positioning mechanism. The high precision self-centering external contracting type tensioning positioning mechanism comprises an axial hollow housing assembly, a compression assembly which can axially contract in the housing assembly and a tensioning assembly which can axially contract in the compression assembly. The high precision self-centering external contracting type tensioning positioning mechanism can achieve rapid installation and positioning, achieves integration effects, is compact and beautiful in structure, low in cost, and capable of automatically releasing, can perform autonomous centering, and meanwhile can achieve flexible or long-distance locking operation, can achieve optimization for a testing space, and can achieve humanized design and arrangement for locking operation actions.

Description

Technical field [0001] The invention relates to the technical field of clamping jigs, in particular to a high-precision self-centering externally-wrapped tightening positioning mechanism. Background technique [0002] With the continuous development of the domestic automobile industry and the increasingly fierce competition in the industry, users have increasingly higher requirements for the quality of automobiles. In order to maintain product competitiveness, OEMs are accelerating the pace of model update and new model launches. Automobile manufacturers are constantly adopting new technologies and new processes, and they have also turned their attention to the development of measurement technology. The development of manufacturing technology is also inseparable from measurement technology. The two complement each other and promote each other. New measurement technology constantly reveals the shortcomings of the new technology, making it further innovation and transformation, an...
