A new-type automobile rear axle hub end face milling device and an operation method thereof

Abstract

The invention discloses a new-type automobile rear axle hub end milling device and operation method thereof, which relates to the technological field of automobile part processing, including a workbench and a PLC control device set on the workbench. The mentioned workbench is equipped with a positioning tooling. The rear axle hub of the automobile is set on the positioning tooling, and a servo system execution device is set on the symmetrical side of the positioning tooling. The servo system execution device is electrically connected with the PLC control device, operation process is simple. Controlling the servo system execution device through the PLC control device has features such as high precision, high stability and fast response, which effectively replaces the hydraulic systems and avoids an oil leakage phenomenon in the hydraulic system and regular replacement of oil seals and hydraulic oil, effectively improving the efficiency and reducing the costs. Through the touch screen of the PLC control device, the parameter setting on the servo system execution device is convenient and quick while improving the work efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a novel automobile rear axle hub end face milling device and an operating method thereof. Background technique [0002] The rear axle assembly of the torsion cantilever beam structure of the automobile is assembled and welded by various parts. After the welding of the assembly is completed, the end face of the hub needs to be milled to meet the requirements of four-wheel alignment. [0003] The power head of the early rear axle milling machine adopted a hydraulic control system, and the thickness of the hub surface was milled manually by observing the instrument value and manually adjusting the left and right dimensions. [0004] The hydraulic control system has the following problems: [0005] 1. The hydraulic station is prone to oil leakage, which is not conducive to 5S on-site management. [0006] 2. The service life of the cylinder oil seal is limited, ...

AI Technical Summary

Problems solved by technology

[0005] 1. The hydraulic station is prone to oil leakage, which is not conducive to 5S on-site management

[0006] 2. The service life of the cylinder oil seal is limited, and a large amount of manpower is required to replace the cylinder seal ring regularly

[0007] 3. The life of the hydraulic oil in the hydraulic station is 1 year, which needs to be replaced regularly, which increases the cost of use

[0008] 4. The feed of the hydraulic cylinder is controlled by a solenoid valve. The feed oil volume of the hydraulic oil is not easy to control, and the feed speed is not stable, which leads to the uneven end surface of the hub and affects the four-wheel alignment.

[0009] 5. The manual labor intensity is complicated, and it is necessary to manually adjust the left and right dimensions according to the calculation of the instrument value, which is easy to produce unqualified workpieces
