A tightening device for vehicle assembly

Abstract

The invention relates to a tightening device for assembling a vehicle, and belongs to the technical field of automobile assembling equipment. The tightening device for assembling the vehicle comprises a moving trolley, wherein a lifting device is fixed on the moving trolley; a side surface of the lifting device is slidably connected with a slider; the upper part of the slider is fixedly connected with a bearing lower fixing plate; the bearing lower fixing plate is arranged horizontally; the upper end of the bearing lower fixing plate is fixed with the bottom of a sliding sleeve; the sliding sleeve is positioned above the bearing lower fixing plate; a rotating shaft is arranged in the sliding sleeve and is slidably connected with a bearing upper fixing plate penetrating through the rotating shaft through a bearing; the bearing upper fixing plate is positioned above the sliding sleeve and is arranged horizontally; a horizontal reaction plate is arranged above the bearing upper fixing plate, is fixedly connected with the bearing upper fixing plate, and is slidably connected with a reaction sleeve; and a servo wrench is fixed on the reaction plate. By the tightening device for assembling the vehicle, the problems that in a tightening assembling process, a force of reaction is over large and impacts people, and safety of people cannot be ensured are solved, and tightening precision is guaranteed.

AI Technical Summary

Problems solved by technology

[0002] When the existing tightening equipment assembles vehicle parts, the sleeve of the tightening equipment cannot rotate the servo wrench body during the process of rotating the bolt to reach the final angle, otherwise the rotation will interfere with the final bolt rotation angle, resulting in over-tightening or false tightening defects , Overtightening will cause the bolts to elongate or even break, and false tightening will cause the bolts to loosen during driving

Due to the large torque of the angle tightening equipment and the large reaction force during the tightening process, the requirements for the tightening equipment are relatively high, which cannot be achieved by manual assembly. Especially during the tightening process, the servo wrench must not shake or shake, otherwise the assembly accuracy will be greatly reduced. , because the final torque of the angle method is very large, if you hold the servo wrench by hand, you can’t hold it, and it may cause a safety risk

In the existing technology, the tightening equipment generally adopts robots or hard manipulators, and auxiliary braking devices, which have the defects of large volume, complex structure, and high manufacturing cost.
