Abstract

The invention provides a method for processing a shifting fork of automobile parts, which comprises the following steps: according to the requirements of a drawing, drilling a through hole and lathing the end face and downside surface of a convex plate; boring the through hole; raising a core rod and lathing the end face of the convex plate; milling the planes of two feet; milling openings; drilling, expanding and reaming two phi8<+0.045> holes on the outer circles of the machined hole; performing heat treatment through carbonitriding till the surface hardness reaches 59 to 63 HRC and the effective hardened depth reaches 0.1 to 0.3 millimeter; honing inner holes, wherein the position degree between the inner holes and the two phi8 holes is required to be less than phi0.1; testing with corresponding measuring tools and apparatuses; and deburring, washing, applying oil on, packaging and warehousing the shifting fork. The method fully guarantees the product in terms of symmetry, position degree, work hardness and high quality, greatly 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 shift fork of auto parts. Background technique: [0002] At present, the shift fork products of auto parts cannot be guaranteed in terms of 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. Invention content: [0003] The purpose of the present invention is to provide a method for processing the shift fork of auto parts, which can well overcome the problems of the above products. The purpose of the present invention is achieved in this way. The processing method of the shift fork of auto parts is characterized in that; Side, and control the thickness of the part, turning the end face of the boss and chamfering; boring the through hole, and chamfering; pulling the hole; pulling up the clamp, pulling the bored hole, leaving a honing allowance; , tu...
