Shaft end bolt tightening auxiliary operation system and method based on time sequence

Abstract

The invention discloses a shaft end bolt tightening auxiliary operation system based on the time sequence. The shaft end bolt tightening auxiliary operation system comprises a main body device, and the main body device comprises a supporting main body, a positioning mechanism, a shell and a detection unit. The positioning mechanism comprises a movable clamping jaw, first fixed clamping jaws, a second fixed clamping jaw and a detection unit. The detection unit comprises a control circuit module, a power supply module, a wireless communication module, a signal digital-to-analog conversion module, a sensing indication module and an upper computer module, wherein the power supply module, the wireless communication module, the signal digital-to-analog conversion module and the sensing indication module are in communication connection with the control circuit module, and the upper computer module is arranged on a mobile terminal. The sensing indication module is aligned with a to-be-screwed bolt through the positioning mechanism, the upper computer module sends an instruction according to an operation time sequence, the detection unit receives the instruction and sends an acousto-optic indication, and an operator completes the screwing operation of the bolt according to the acousto-optic indication. Operation is easy, and operation sequence errors can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of bolt assembly, and more specifically relates to a time-series-based auxiliary operation system and method for tightening bolts at the end of an axle. Background technique [0002] The axle shaft end is an important part of the axle overhaul. During the overhaul process, the tightening of the axle end cover bolts has strict requirements on the torque. It must be tightened in a specific order and must not be repeated. Once the tightening sequence does not meet the requirements and occurs In the case of repeated tightening or missed tightening, the final torque of bolt tightening will not meet the standard, which will cause great hidden dangers to the operation of the train. [0003] At present, the quality control of the bolt tightening operation of the peripheral end cover depends entirely on the independent control and confirmation of the operators. First of all, the worker's experience and memory are us...
