Method for processing forward gear shifting block of automobile parts

Abstract

The invention discloses a method for processing a forward gear shifting block of automobile parts, which comprises the following steps: according to the requirements of a drawing, performing lathing, drilling a through hole, lathing an end face and boring the through hole; raising a core clamp and lathing the other end face; milling the end faces by taking the end face of a first lathe as a reference; milling a large plane vertical to a hole center by taking an machined inner hole as a reference; milling an upper plane parallel to the hole center by taking the machined inner hole and the large plane as references; milling openings and feet R; drilling, expanding and reaming the through hole on the machined inner hole; performing heat treatment through carbonitriding till the surface hardness reaches 59 to 63 HRC and the effective hardened depth reaches 0.3 to 0.5 millimeter; honing the inner hole; doing tests by using corresponding measuring tools; and packaging the forward gear shifting block after cleaning and deburring the product and warehousing the product. The method guarantees the parallelism, symmetry, position level, hardness and high quality of the products, prolongs the service life of the product and meets the requirements for the rapid development of the automobile industry.

Description

Technical field: [0001] The invention relates to auto parts, in particular to a processing method for a forward shift block of an auto part. Background technique: [0002] The current forward shift block products of auto parts cannot be guaranteed in terms of parallelism, symmetry, position and product hardness. The product quality is poor and the service life is short, which cannot meet the needs of the rapid development of the auto industry. content of the invention; [0003] The purpose of the present invention is to provide a method for processing the forward shift block of auto parts, which can well overcome the problems of the above products. The object of the present invention is achieved in this way. The processing method of the forward shift block of the auto parts is characterized in that: car: put on the lathe and clamp, drill through holes, and ensure that the thickness deviation of the hole arm does not exceed 0.5; Evenly distributed; boring through hole, lea...
