Numerical control electric screwdriver and control method based on static torque sensor

Abstract

The invention discloses a numerically controlled electric screwdriver based on a static torque sensor, which includes a connected control box and a screwdriver, and is characterized in that: the control box includes a box body, a touch screen is arranged on the box body, a controller and a Switching power supply, the controller includes a signal processing module, an acquisition main control module, a motor drive module and a display input module, the screwdriver includes a shell, the shell is provided with a connected motor, a reduction box and an output spindle, and there is at least one angle sensor in the motor , a static torque sensor is installed outside the output spindle, and one end of the output spindle extends out of the shell and is connected with the batch nozzle. At the same time, the control method of the CNC electric screwdriver is also introduced. Based on the above structure and control method, the present invention has multiple functions such as good data management and fault detection, and has the advantages of low cost, long life, high precision, safety and reliability, and can be widely extended to the assembly of various precision parts .

Description

technical field [0001] The invention relates to a screw tightening tool, in particular to a numerically controlled electric screwdriver based on a static torque sensor and a control method thereof. Background technique [0002] With the rapid development of China's automobile, aerospace, machinery and other industries, the assembly requirements for various precision mechanical parts are getting higher and higher. Screwdrivers are important tools for screwing screws and are widely used in various assembly processes. Therefore Improving the automation of tightening tools has become a top priority. At the same time, while the automatic control of the screwdriver is realized, the torque control accuracy and intelligence requirements of the screwdriver are also correspondingly improved. The screwdrivers currently on the market mainly include: first, the mechanical clutch structure, which is complex in structure, low in precision, and high in maintenance costs; The structure of ...

AI Technical Summary

Problems solved by technology

This tightening device can significantly save costs and has good torque accuracy, but this product lacks good data management and fault detection functions, the degree of automation and work efficiency is not high, and it cannot support multi-task mode, so it is difficult to adapt to the diverse needs of different assembly fields
