Torque automatic control system for electric screwdriver

Abstract

The invention discloses a torsion automatic-controlling system used for an electric screw driver. The torsion automatic-controlling system used for the electric screw driver can automatically control the electric screw driver to stall accurately according to preset torsion, and the electric screw driver controlled by the torsion automatic-controlling system used for the electric screw driver can completely replace an existing widely-used mechanical torque-locking electric screw driver. The torsion automatic-controlling system used for the electric screw driver monitors the working state of the screw driver in real time through sensors, and signal acquisition regulation and ARM software and hardware technologies, once the torsion of the screw driver reaches a preset value, the screw driver stalls rapidly to enable the tightness degree of screws to meet preset requirements, the fact that combination of the locked screws and a workpiece reaches set torsion is ensured, and therefore the situation of excessive loosening and excessive tightening of screws is prevented from occurring. In addition, online monitoring of the operation situations of the screws during an automatic production process can be achieved, online monitoring of torsion difference is achieved, and online setting of torsion values of different screw drivers is achieved.

Description

technical field [0001] The invention relates to a torque automatic control system for an electric screwdriver. Background technique [0002] Electric screwdrivers have been widely used in the modern manufacturing industry, especially the electronic digital product manufacturing industry, because they can quickly lock the screws and set the locking torque, and have made great contributions to product standardization and mass production. However, with the upgrading of manufacturing technology and products, especially the higher and higher quality requirements for electronic digital products, the stricter requirements for product manufacturing processes and the rapid development of factories towards high intelligence and fewer people, The traditional mechanical torque setting method of electric screwdrivers lags behind in the production automation process due to the shortcomings of inaccurate torque setting, uncontrollable torque overload, cumbersome torque setting, and the nee...

However, with the upgrading of manufacturing technology and products, especially the higher and higher quality requirements for electronic digital products, the stricter requirements for product manufacturing processes and the rapid development of factories towards high intelligence and fewer people, The traditional mechanical torque setting method of electric screwdrivers lags behind in the production automation process due to the shortcomings of inaccurate torque setting, uncontrollable torque overload, cumbersome torque setting, and the need for frequent adjustments. Due to the development of other manufacturing equipment, processes and technologies, it can no longer meet the requirements of modern manufacturing industries for electric screwdrivers
