AI Technical Summary
The existing tightening process of bolts, nuts, etc. in automobile manufacturing lacks intelligent and rapid detection methods, resulting in low tightening efficiency and inaccurate tightening status judgment.
A height measurement and verification device and an intelligent tightening system are designed to determine the tightening status by measuring the height of the studs, nuts, etc. after tightening. The height measurement and verification device and the intelligent tightening system are used to achieve fully automated operation. Combined with components such as displacement drive, sliding module, detection mount and floating altimeter, height measurement and tightening status detection are achieved.
It realizes the fully automated and intelligent operation of fasteners such as bolts and nuts, improves the tightening efficiency and qualification rate, and meets the efficient unmanned control requirements of intelligent manufacturing.
