Platform floating tightening mechanism

The utility model relates to the technical field of automobile part assembly, and discloses a platform floating tightening mechanism which solves the problems that an existing manual tightening mode is low in working efficiency and poor in tightening quality, and the labor fatigue of workers is increased. The lower ends of the four annular chains are all connected with fixing blocks, one sides of the upper ends of the four fixing blocks are all connected with supporting rods, and the upper ends of the supporting rods are connected with middle plates. The floating tightening function is achieved through the structure, the production requirement can be met by effectively solving the problems that an overall hole distance combination is large in target position deviation and long in hole position distance, and compared with a manual tightening mode, the tightening mode is high in working efficiency and tightening quality, and the labor cost is reduced. 本实用新型涉及汽车零部件装配技术领域，且公开了一种平台浮动拧紧机构，解决了目前人工拧紧方式工作效率低、拧紧质量差，以及增
