Problems solved by technology

[0002] At present, in the process of assembling industrial products, fastening bolts and screws is an extremely important operation link, but now the method of directly controlling the pretightening force through torque is generally used, and the accuracy of the bolt tightening degree is poor, because the tightening torque It is greatly affected by the fluctuation of the friction coefficient, and the existing equipment is not suitable for the tightening operation of large bolts, which urgently requires those skilled in the art to solve the corresponding technical problems

Abstract

The invention provides a high-reliability bolt tightening system. The high-reliability bolt tightening system is characterized in that a mechanical arm is connected with one end of a front arm, the other end of the front arm passes through a connecting part, the connecting part is further connected with one end of an arc arm, the other end of the arc arm is connected with a rotating disc, the rotating disc is connected with a base, a groove is formed in the bottom of the base, the groove is arranged in a sliding rail in a sedimentation manner, a fastening device is arranged at the head of the mechanical arm, a bolt sleeve is obtained through the fastening device, and a bolt is tightened on the corresponding component through the sleeve. According to the system, bolt tightening operation can be finished through angle adjustment, corresponding operation is carried out through the fastening device, and the system is safe and convenient.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a high-reliability bolt tightening system. Background technique [0002] At present, in the process of assembling industrial products, fastening bolts and screws is an extremely important operation link, but now the method of directly controlling the pretightening force through torque is generally used, and the accuracy of the bolt tightening degree is poor, because the tightening torque It is greatly affected by the fluctuation of the friction coefficient, and the existing equipment is not suitable for the tightening operation of large bolts, which urgently requires those skilled in the art to solve the corresponding technical problems. Contents of the invention [0003] The present invention aims at at least solving the technical problems existing in the prior art, and particularly innovatively proposes a high-reliability bolt tightening system. [0004] In order to achieve ...
