Method for processing differential case assembly

Abstract

The invention provides a method for processing a differential case assembly, which comprises the steps of processing a front half case of a differential, processing a back half case of the differential, performing induction quenching on excircle surfaces of small ends of two workpieces and within 25mm of a shoulder step, and assembling the differential case assembly. In the assembling process, two half cases are connected firmly by eight bolts, the coaxiality is corrected on special equipment and not allowed to exceed phi0.025, and the end jump is not more than 0.025; excircles are ground, wherein double core clampers grind the excircles and end faces of the two half cases of the differential, and all machining dimensions are ground to meet the requirements of a drawing; a crossed hole is milled, wherein a mill chuck is arranged and clamped, and a crossed hole is milled on a fit position of the two half cases according to the requirements of the drawing; and the machining dimensions are detected by corresponding measuring tools. The method is a good processing method, which can save a product, ensure product quality, prolong the service life of the product, reduce cost and promote enterprise development.

Description

technical field [0001] The invention relates to auto parts, in particular to a processing method for the differential case assembly of the auto parts. Background technique [0002] Due to the rapid development of the national economy, the sales of automobiles have also increased rapidly correspondingly, but at the same time it has also brought many problems. Among them, the fracture of the differential case of auto parts is not uncommon. The product has low strength, small static torsional torque, and is easy to break. , low lifespan. It has brought great losses and troubles to enterprises and users. Contents of the invention [0003] The purpose of this invention is to provide a kind of processing method of differential case assembly, which can well overcome the problems existing in the above products, and the purpose of the present invention is achieved in this way, the processing method of differential case assembly , characterized in that: processing the front half s...
