Problems solved by technology

[0002] In electric power maintenance work, operators often need to carry out bolt fastening work at high altitude. At this time, the strength of bolt fastening mostly depends on the operator's experience judgment. This traditional bolt fastening method is not only dangerous, but also Quality is also difficult to guarantee
Based on the consideration of the safety of the operators, while further improving the accuracy of bolt tightening, the current working method is no longer applicable

Embodiment

[0044] Embodiment: The preset torque value is 20Nm, the maximum value of the rotational speed detection sensor is set to 30 revolutions per second and the minimum rotational speed is 5 revolutions per second. To start working, first judge whether the deviation of the angle value is within 10 degrees, if it meets the requirements, start working, and output a PWM wave with a duty cycle of 60% and a frequency of 30K. At this time, the speed detection sensor detects whether the speed is stable in real time, and the speed is unstable. At this time, the duty cycle of the output PWM wave is modified by the error to stabilize the speed. The torque detection sensor detects whether the real-time detection torque value reaches the preset torque value (deviation 0.1Nm). When the preset value is reached, the motor stops working.

Abstract

The invention discloses a control device of an intelligent bolt fastener and a control method thereof. The device comprises a motor, a detection sensor, a wireless communication module, a handheld control module and a wireless control module. The handheld control module comprises a motor controller and a motor display. The wireless control module comprises a wireless controller and a remote control display. The motor is connected to the detection sensor and the motor controller. The motor controller is connected to the motor display. The motor controller is connected to the wireless controller through the wireless communication module. The wireless controller is also connected to the remote control display. Control of the bolt fastener is subdivided into hand-held control module work and remote control wireless control module work. According to different conditions of a scene, such as a space size, an operation angle size, a construction height and the like, an appropriate control method is selected and an optimal control effect is reached.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a control device and a control method of an intelligent bolt tightener. Background technique [0002] In electric power maintenance work, operators often need to carry out bolt fastening work at high altitude. At this time, the strength of bolt fastening is mostly judged by the experience of operators. This traditional bolt fastening method is not only dangerous, but also Quality is also difficult to guarantee. Based on the consideration of the safety of the operators and the further improvement of the accuracy of the bolt fastening, the current working method is no longer applicable. Contents of the invention [0003] Purpose of the invention: The present invention provides a control device for an intelligent bolt tightener and its control method, which can realize the intelligent control of bolt tightening and the function of obtaining the torq...
