Device and process for machining differential housing

Abstract

The invention belongs to the technical field of automobile manufacturing and discloses a device and process for machining a differential housing. The device is composed of a rotary jig, an internally-expanding lathing jig and a spherical surface lathing jig, wherein the rotary jig is arranged on a machining center and comprises an operation part with the two ends arranged on the machining center through rotating assemblies, and the internally-expanding lathing jig and the spherical surface lathing jig are arranged on a common numerically-controlled lathe. Synchronous machining of two parts can be achieved through the high-precision rotary jig when the machining center is used for machining various axial inner holes, and therefore efficiency is higher; a high-precision numerically-controlled indexing table is applied to the jigs, rotating accuracy is as high as 20'' or higher, and precision of the critical size of a product is better guaranteed; the parts can be automatically clamped and dismounted by the jigs through numerical control programs, and therefore labor can be saved.

Description

technical field [0001] The invention relates to a process and a device in the technical field of automobile manufacturing, in particular to a processing device and a process for a differential housing. Background technique [0002] When the car is running, it is often necessary to change the driving direction. After changing the direction, in order to ensure the stability of the car, the speed of the power output to the wheel hub is different, so that the wheels can produce different linear speeds so that the car can turn smoothly. It is the function of the differential that causes the two driving half shafts to produce different speeds. As an important part, the differential case is not only the active part in the differential assembly, but also the basis for the installation of other components in the differential assembly. [0003] Due to the special and unconventional structure of the differential case, for example, there are many processing surfaces in its shape and in...

Problems solved by technology

However, no specific technical parameters are given in this technology. At the same time, the defects and shortcomings of this technology are: directly processing from the blank to the finished product, the processing cycle of each process is long, the investment equipment is too large, and the investment risk is not clear when the output is not clear. very big

However, this technology needs to manually insert and pull out the oil pipe twice when clamping and disassembling parts, and then manually operate the control valve. The automation and processing efficiency are low. At the same time, the tooling and fixture rely on the ratchet rotary table of the horizontal machining center to rotate, and the accuracy is 1. °1', it is difficult to meet the needs of existing industries
