Problems solved by technology

[0003] The inventor found in the research and development process that the current conventional manual digital display torque wrench circuit control system consumes a lot of power, and the wrench battery charging method generally adopts the in-line charging method, which is easily caused by wear and tear in the wrench industrial application field. It cannot be charged or the charging efficiency is reduced, and there is no separate charge and discharge protection for the rechargeable battery used by the wrench; the human-computer interaction of the wrench is generally poor, and the wrench has not yet had the operator information identification function except for sound, vibration, and light warnings. It is impossible to realize high-level information interaction with the operator; in practical applications, the tightening data of the wrench is easy to be lost, resulting in data disorder. At the same time, the problem of reading and writing the configuration parameters of the wrench will also cause frequent initialization failures of the wrench.
[0004] During the research and development process, the inventor also found that the current wrench has a single communication method with the PC or mobile terminal, and the wrench cannot be compatible with indoor and outdoor data transmission. Especially with the advent of the era of big data, the wrench needs to realize the function of data upload anytime and anywhere

Embodiment 1

[0044] As introduced in the background technology, in the prior art, there are large power consumption of the wrench circuit control system, easy damage of in-line charging, poor information interaction, easy loss of data, and inability to upload data in real time outdoors. In order to solve the above technical problems, This embodiment provides an intelligent digital display torque wrench circuit control system.

[0045] figure 1 It is a schematic diagram of the overall structure of the intelligent digital display torque wrench circuit control system involved in this embodiment. like figure 1 As shown, the control system includes a microcontroller module 1 , a power module 2 , a signal conditioning module 3 , a storage module 4 , an angle detection module 5 , a human-computer interaction module 6 , a communication module 7 , a clock synchronization module 8 and a control terminal 9 .

[0046] Specifically, the microcontroller module 1 is composed of a microcontroller and pe...

Embodiment 2

[0076] Taking the tightening of a fastener of a station component as an example, the steps of the circuit control method for an intelligent digital display torque wrench involved in this embodiment include:

[0077] S101, the PC terminal 91 performs data transmission through the WIFI module 721. When the on-site WIFI is seriously shielded, it automatically switches to the 5G communication module 722 for communication, and the PC terminal 91 sends the wrench tightening qualified interval and angle range to the wrench microcontroller module , through the camera module of the information interaction module 66, the face recognition of the wrench tightening operator is performed, and the station parts are photographed, identified and uploaded, and at the same time, the information of the station parts is scanned and uploaded through the scanning module to ensure that the wrench tightens the station parts correctly. Realize wrench tightening positioning.

[0078] S102. During the ti...

Abstract

The invention discloses an intelligent digital display torque wrench circuit control system and method. The system comprises a signal conditioning module, an angle detection module, a microcontrollermodule, a communication module, a man-machine interaction module and a control terminal. The signal conditioning module collects the value of torque exerted on a wrench in real time and converts the torque value into a digital signal, and the digital signal is transmitted to the microcontroller module. The angle detection module collects the course angle change value in the wrench screwing processand transmits the courses angle change value to the microcontroller module. The microcontroller module calculates the wrench screwing angle value according to the received course angle change value in the wrench screwing process, the wrench screwing angle value and the torque value are uploaded to the control terminal through the communication module, meanwhile the microcontroller module is usedfor comparing the wrench screwing angle value and the torque value with the set values, and the man-machine interaction module is used for conducting alarming prompting on whether wrench screwing is qualified or not.

Description

technical field [0001] The invention relates to the technical field of control circuits, in particular to an intelligent digital display torque wrench circuit control system and control method. Background technique [0002] With the improvement of the quality of my country's manufacturing products and the rapid development of the intelligent assembly industry, the manufacturing industry, especially the automobile, railway, aerospace and other industries, has higher and higher requirements for torque accuracy in the assembly and tightening process, especially for high-precision equipment, high-speed Strength components have very precise torque requirements, and threaded fasteners must be assembled within a set torque range. At the same time, with the development of the intelligent assembly industry, the manufacturing industry's demand for torque wrenches is not limited to the torque of the tightened fasteners. The control of precision should also meet the needs of other functio...
