Automatic intelligent electric screwdriver based on torque and pressure composite force sensor

Abstract

The invention relates to the technical field of electric screwdrivers, and provides an automatic intelligent electric screwdriver based on a torque and pressure composite force sensor and a control method of the automatic intelligent electric screwdriver. The automatic intelligent electric screwdriver based on the torque and pressure composite force sensor comprises a base; a motor; one end of the torque and pressure composite force sensor is fixed on the base, and the other end of the torque and pressure composite force sensor is connected with the motor; the screwdriver head structure comprises an electric screwdriver core shaft and a screwdriver head, and the two ends of the electric screwdriver core shaft are coaxially connected with the motor shaft and the screwdriver head respectively; and a sensor aviation plug and a motor aviation plug are arranged on the fuselage shell. According to the automatic intelligent electric screwdriver based on the torque and pressure composite force sensor, tightening torque and assembly pressure data in the screw locking process can be collected and monitored in real time, and the consistency and reliability of operation quality and the controllability of assembly pressure are greatly improved while ultrahigh tightening precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric batch, in particular to an automatic intelligent electric batch based on a torque and pressure composite force sensor and a control method thereof. Background technique [0002] Smart electric screwdriver is a commonly used tightening tool, mainly used for high-precision tightening and free loosening of screws with specific torque. [0003] At present, most of the popular automatic tightening tools on the market are ordinary electric screwdrivers, which have low precision and cannot meet the high-end market's demand for high-quality assembly and tightening, let alone guarantee the quality and life of the products. [0004] In the prior art, in order to control the output torque of the motor, the output torque information is generally obtained through the output current of the motor for control. However, this torque information is different from the actual tightening torque, and the tightening acc...
