The invention provides a high-reliability bolt screwing circuit system and a control method thereof. A motor control end of a single-chip microcomputer is connected with a servo motor driving system of a bolt screwing system, an electromagnetic control end of the single-chip microcomputer is connected with a signal end of an electromagnetic coil, a laser signal end of the single-chip microcomputeris connected with a signal end of a laser sensor, and a torque signal end of the single-chip microcomputer is connected with a signal end of a torque sensor. Bolt screwing operation is conducted through automatic control. By means of the method, automatic positioning can be realized according to the bolt assembling position, the self-adaptive adjustment of the screwing torque is realized according to working conditions, sleeves of different types are automatically replaced, visual bolt assembling is realized, labor cost is greatly reduced, the bolt screwing efficiency and reliability are improved, and intelligent bolt assembling is realized.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a control method for a high-reliability bolt tightening circuit 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 control method for a high-reliability bolt...
