Description

Vertical and horizontal three-sided boring and facing machine tool

Technical Field

The utility model relates to the technical field of bridge housing processing machine tools, in particular to a vertical and horizontal three-side boring and end surface turning combined machine tool.

Background Art

The rear axle housing of a car is an important part of the car. It forms a drive axle with the main reducer, differential and wheel transmission. The drive axle is at the end of the power transmission system. Its maneuvering function is to increase the torque transmitted by the drive shaft or transmission and reasonably distribute the power to the left and right drive wheels. In addition, the drive axle housing is also an important load-bearing and force-transmitting part of the car. The drive axle housing not only supports the weight of the car and transmits the load to the wheels, but also bears the traction, braking force, lateral force, vertical force reaction force and reaction torque transmitted by the drive wheels, and transmits them to the frame or body through the suspension.

The processing of the inner holes at both ends of the bridge shell, the end faces, the middle lute holes, and the upper and lower end surfaces are the key processes in the processing of the bridge shell.
