Problems solved by technology

[0003] Since the tightening torque of the bolts connecting the airbag base and the I-beam of the front axle can reach up to 800NM, only relying on the pneumatic wrench for tightening is not only labor-intensive, but also the tightening torque cannot be guaranteed, and the work efficiency is also very low

Abstract

The invention discloses a passenger car front axle offline preassembling system and a front axle automatic tightening and supporting device. The system is used for tightening bolts of a front axle I-beam and an air bag base, and the system comprises a supporting device body, positioning unit rail assemblies, positioning units, a translation mechanism and automatic tightening equipment, wherein the supporting device body comprises a left supporting table, a right supporting table and a movable tightening area located between the left supporting table and the right supporting table, the positioning unit rail assemblies are arranged on the left supporting table and the right supporting table respectively, and the translation mechanism is arranged in a movable tightening area, has a height difference with the positioning unit rail assemblies and is used for arranging the automatic tightening equipment. The positioning units are arranged on the positioning unit rail assemblies, one positioning unit located on the left supporting table and the other positioning unit located on the right supporting table conduct V-shaped supporting on a front axle at the two ends of the front axle, and the automatic tightening equipment can move front, back, left and right on the translation mechanism to be adjusted so as to be aligned to the positions of multiple bolts on the front axle. The system can replace a traditional operation mode of manually tightening the bolts on the front axle.

Description

technical field [0001] The invention relates to an off-line pre-installation system of a front axle of a passenger car and an automatic tightening support device for the front axle. Background technique [0002] At present, most of the front air suspension systems of passenger cars are connected offline with the airbag base and the I-beam of the front axle, and then installed online as a whole. [0003] Since the tightening torque of the bolts connecting the airbag base and the I-beam of the front axle can reach up to 800NM, only relying on the pneumatic wrench for tightening is not only labor-intensive, but also the tightening torque cannot be guaranteed, and the work efficiency is also very low. [0004] Therefore, it is necessary to provide an off-line pre-installation system for the front axle of a passenger car to replace the manually operated pneumatic wrench tightening method, so as to improve work efficiency and stabilize product quality.
