The positioning module of the beam straightener is an important component to ensure vehicle stability and accurate measurement during the body correction process. However, the current conventional general positioning modules are mainly used for limiting and fixing through the positioning holes at the bottom of the vehicle.

Each assembly plate and the base plate are positioned by two cylindrical locating pins, and tightened by two sets of tightening mechanisms for flexible quick-change inspection fixture devices. After the sleeve and the precision aluminum profile are connected, they are fixed vertically on the assembly plate together, and the slide rail is also inserted into the inner cavity of the sleeve and the precision aluminum profile in the vertical direction to achieve up and down sliding cooperation. The slide rail is fastened to the sleeve by a locking handle, and the double angle adjustment The entire mechanism is fixed to the top of the slide rail by means of hexagon socket bolts and cylindrical locating pins, the cross slider fine-tuning mechanism is fixed to the top of the double-angle adjustment mechanism by means of hexagon socket bolts and cylindrical locating pins, the adjustable fixing seat of the quick clamp is fixed to the top of the cross slider fine-tuning mechanism by means of hexagon socket bolts and cylindrical locating pins, the positioning surface angle fine-tuning mechanism is fixed to the adjustable fixing seat of the quick clamp by means of locating bolts, and the quick clamp is fixed to the adjustable fixing seat of the quick clamp by means of hexagon socket bolts. Although the spatial angular position of the locating points (surfaces) of the fixture, inspection fixture, and detection bracket can be adjusted through the above scheme, the adjustment method is single. In order to be applicable to more vehicles, we urgently need a special multi-directional and multi-angle positioning module. Utility Model Content
