Abstract

The invention provides a rear axle lining press-fitting machine and relates to a press-fitting machine. The rear axle lining press-fitting machine comprises two sets of press-fitting devices which are symmetrically arranged, wherein each set of the press-fitting device comprises a main hydraulic cylinder, a main pressing head, a secondary hydraulic cylinder, a secondary pressing head, a main guide rail and a secondary guide rail; a stretching-out end of each main hydraulic cylinder is connected with the corresponding main pressing head; the bottom of each main pressing head is in sliding fit with the corresponding main slide rail; each main pressing head is connected with a lining; the stretching-out end of each secondary hydraulic cylinder is connected with the corresponding secondary pressing head; each secondary pressing head is in sliding fit with the corresponding secondary guide rail; and each secondary pressing head is connected with a rear axle assembly sleeve of the corresponding lining to be subjected to press fitting. With the adoption of the rear axle lining press-fitting machine, the operation of putting in and taking out a rear axle assembly becomes relatively easy; and the rear axle lining press-fitting machine has the characteristics of convenience for press fitting, high press fitting precision and efficiency, capability of displaying a working result in real time and simple structure, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a press-fitting machine, in particular to a rear axle bushing press-fitting machine. Background technique [0002] With the continuous development of society, the demand for cars is increasing. The rear axle is a component used by the car to support the wheels and connect the rear wheels. For rear-wheel drive cars, the rear axle is used as a drive axle. In addition to carrying the load, it also plays the role of driving, deceleration and differential speed. Bushings are usually assembled in the rear axle assembly to play the role of shock absorption, cushioning and protection. Due to the interference fit between the rear axle assembly and the bushing, a large external force is usually required during assembly, and the requirements for assembly accuracy are also high. Therefore, manually assembling and pressing is not only time-consuming and laborious, but also prone to improper assembly. Authorized announcement number CN2020...
