Air suspension U-bolt tightening device

Abstract

The invention discloses an air suspension U-bolt tightening device. The air suspension U-bolt tightening device comprises a supporting frame, a lateral guide rail, a longitudinal guide rail, an operating body, two tightening shafts connected with the operating body, a cable bridge and an electric cabinet, and the lateral rail is arranged on the inner side of the bottom of the supporting frame, thelongitudinal rail is slidably connected to the lateral rail through first sliders at both ends of the longitudinal rail, and a base of the operating body is slidably connected to the longitudinal rail through second sliding blocks; a turntable is arranged at the bottom of the operating body, and the operating body realizes adjustment within the circumferential range by the rotation of the turntable; and the cable bridge is a signal transmission carrier for connecting the electrical cabinet and the operating body. The tightening torque of the tightening device and a tightening shaft head are adjustable, the operation flexibility is high, automatic tightening of two U-bolts is realized, the quality of products is ensured, the production efficiency is improved, the labor intensity is reduced, and the defects of an existing U-bolt tightening device with poor operability and low production efficiency are overcome.

Description

technical field [0001] The invention relates to the technical field of bolt assembly machinery, in particular to an air suspension riding bolt tightening device. Background technique [0002] At present, the competition in the passenger car market is more intense, and the manufacturing technology of passenger cars is also developing rapidly. The key process of the pre-installation of the rear air suspension of the passenger car is the tightening of the saddle bolts. The wrench is used for tightening. Due to the large tightening torque, when tightening with a torque wrench because the rear air suspension and the rear axle assembly have no pressing device, there is a great potential safety hazard. At the same time, the labor intensity of the workers is very high and the work efficiency is low. It is difficult to meet the demand of rhythmic production, so it is more and more necessary to design and manufacture a fixed-torque tightening device for passenger car rear suspension a...
