High-precision split charging device for single rear axle of commercial vehicle

Abstract

The invention discloses a high-precision split charging device for a single rear axle of a commercial vehicle. The device comprises two sets of split charging clamps which are arranged left and right. Each set of split charging clamp comprises a bolt positioning clamp used for positioning a U-shaped bolt; main spring positioning clamps located on the front side and the rear side of the bolt positioning clamp and used for positioning the two ends of a main spring; and auxiliary spring positioning clamps located on the front side and the rear side of the bolt positioning clamp and used for positioning the two ends of an auxiliary spring. The two sets of split charging clamps are both arranged on front-back adjusting mechanisms used for adjusting the front-back positions of the bolt positioning clamps, the front-back positions of the main spring positioning clamps and the front-back positions of the auxiliary spring positioning clamps, and at least one front-back adjusting mechanism is connected with a left-right adjusting mechanism used for driving the front-back adjusting mechanism to move left and right. By means of the mode that the main spring and the auxiliary spring of the single rear axle assembly are respectively positioned, the problem of plate spring positioning accuracy is solved, and high-accuracy split charging of the single rear axle assembly of the commercial vehicle becomes possible.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a high-precision subassembly device for a single rear axle of a commercial vehicle. Background technique [0002] At present, the positioning method of single rear axle subassembly is: use U-shaped bolts for intermediate positioning, and leaf springs on both sides for auxiliary positioning. Since the U-shaped bolt and the U-shaped positioning groove must keep a gap of more than 2mm, otherwise the rear axle assembly will be easily stuck when hoisting after sub-assembly. The frequency of assembly difficulties is high, and there are many line stops. [0003] The application number is: CN201920799474.5, and the patent name is "A Supporting Tooling Applicable to Single Rear Axle and Double Rear Axle Installation", which discloses a support tooling suitable for single rear axle and double rear axle installation, which belongs to In the field of process equipment, it ...

AI Technical Summary

Problems solved by technology

[0005] Although the above comparative document discloses the fixed tooling of the single rear axle of the automobile, the rear axle assembly after the single rear axle is subassembled is still easy to be stuck when hoisting , leading to difficulties in hoisting, the reason is that the positioning structure is not accurate enough, resulting in large deviations in the on-line of the single rear axle assembly, high frequency of on-line assembly difficulties, and many line stoppages
