Mounting tool for bolt and nut assembly

Abstract

The invention discloses a mounting tool for a bolt and nut assembly. The mounting tool comprises an L-shaped plate, a sliding plate, bolt sleeves and nut sleeves. One end of the L-shaped plate is sleeved with one end of the sliding plate. The sliding plate and the L-shaped plate form an inverted concave shape, and the sliding plate can slide on the L-shaped plate. The bolt sleeves are vertically arranged at the other end of the sliding plate. The nut sleeves are vertically arranged at the other end of the L-shaped plate. The bolt sleeves and the nut sleeves are oppositely arranged. According to the mounting tool for the bolt and nut assembly, the bolt sleeves are correspondingly arranged at both ends of the tool, the sleeve at one end is fixed, and the sleeve at the other end is connectedwith an electric torque fixing tool, so that the problem that bolts and nuts rotate at the same time in the tightening process is solved, and the fastening requirement is met.

AI Technical Summary

Problems solved by technology

[0002] When bolts and nuts are assembled on the workpiece, one end of the bolt or nut needs to be fixed and then the other end is tightened. If there is no special tooling, the bolt and nut will rotate at the same time when tightening, the target torque cannot be achieved, and the product quality is difficult to guarantee;

[0003] When a large number of bolts and nuts are installed, if they are tightened manually with a torque wrench, the labor intensity will be high and the production efficiency will be low;

[0004] Usually, the torque of bolt tightening is very large, and high precision must be ensured, but the reaction force generated during the tightening process will act on the workpiece and the operator at the same time, and due to the limitation of the structure of the workpiece, the reaction force cannot be eliminated by the workpiece itself, posing a safety hazard

[0005] If a special tooling is designed for one product, it cannot be used for other products, and the universality of the tooling is poor
