AI Technical Summary
In existing technologies, the torque method for tightening nuts is inefficient, while the tension method for tightening nuts is difficult to control the degree of tightening.
The system employs a combination of a support sleeve, ratchet wrench, drive assembly, jacking assembly, length measuring assembly, and controller. After tensioning the bolt to a preset tension value, the drive assembly tightens the nut, and the length measuring assembly monitors changes in bolt length to control the degree of tightening.
It improves tightening efficiency and ensures the accuracy of nut tightening. The entire process is completed within 2 minutes, solving the problems of low efficiency and control in existing technologies.
