Description

Technical Field

[0001] The invention belongs to the technical field of vehicle axle component equipment, and in particular relates to a micro-panel spring type vehicle axle U-bolt fastening auxiliary tooling. Background Art

[0002] Vehicle production by automobile companies is all order-based production, that is, orders are placed first and then production is scheduled. Vehicle sales have off-seasons and peak seasons, resulting in large fluctuations in monthly production plans. Some automobile companies prepare spare production lines to be used when monthly production increases exceed the load of the main line. In order to reduce the investment in fixed assets, the auxiliary equipment of their spare production lines will tend to be simple, light-capital and practical.

[0003] If a tightening machine (4-axis) is used to tighten the U-bolts of the leaf spring axle of a microvan, the equipment cost is about 500,000 yuan for a single machine on one side, and the total cost is about 1 million yuan for each machine on the left and right sides. If the tightening machine equipment is only used for the spare production line, its equipment utilization rate is low, the investment is large, it is not cost-effective, and it is a bit wasteful. However, if a tightening machine is not used, the tightening torque of the U-bolt is generally large (200N.m-500N.m), and its special fixed-torque air gun weighs about 5Kg. The manual lifting of the air gun for tightening is more laborious, consumes a lot of physical strength, and the ergonomics is unreasonable. When the lifting force is not enough, there is a risk of unsatisfactory tightening effect. Summary of the invention
