Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] like figure 1 , The tightening machine is composed of two parts: the control system and the driving actuator. The control system is composed of an industrial computer and 4 single-chip axis control units; The axis control unit uses a single-chip microcomputer as the core controller.

[0015] The actuator is composed of AC servo motor, angle sensor, torque sensor, reducer and power output shaft. Each axis control unit independently controls a set of actuators. 4 sets of actuators are installed in the headstock, and the automatic tightening process is completed by operating the headstock.

[0016] like figure 2 , The monitoring unit adopts industrial computer as the hardware platform, through the monitoring software of the industrial computer to realize the setting of the predetermined torque value, the dynamic data of the tightening process, the real-time dis...

Abstract

The invention discloses a nut tightener control system, and the system consists of an industrial control computer and four single-chip microcomputer shaft control units. The industrial control computer is a monitoring operation station, and can achieve the setting of technological parameters and the displaying of the technological parameters. The shaft control units take the single-chip microcomputers as the core controller. The control system employs a torque closed loop control and intelligent control algorithm, achieves the high-precision control of torque, and improves the production efficiency and assembly precision.

Description

Technical field [0001] The invention relates to a control system of a nut tightening machine, which is suitable for the mechanical field. Background technique [0002] Threaded connection has been widely used in various products due to its simplicity, reliability and easy disassembly. Especially in important stations such as engines in the automotive industry, there are high requirements for the size and accuracy of the tightening force. Due to the high cost performance of imported tightening machines and the single use of stations, some domestic automobile manufacturers still use pneumatic or hydraulic wrenches, which are difficult to guarantee accuracy, and have disadvantages such as high labor intensity, low production efficiency, and unstable product quality. Contents of the invention [0003] The invention proposes a nut tightening machine control system, which adopts torque closed-loop control and intelligent control algorithm, realizes high-precision control of tor...
