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, positiondegree, 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

The processing method of shifting fork of automobile parts
Technical field: the present invention relates to auto parts machinery, particularly relate to a kind of processing method of shifting fork of automobile parts.
Background technology: the shifting fork of automobile parts product can not get assurance aspect symmetry, position degree and the product hardness at present, poor product quality, and service life is short, can not satisfy the needs of automobile industry develop rapidly.
Summary of the invention: purpose of the present invention is exactly the processing method that a kind of shifting fork of automobile parts will be provided, and it can overcome the existing problem of above product well.The object of the present invention is achieved like this, and the processing method of shifting fork of automobile parts is characterized in that; Car: get on the bus the folder and clamp big plane, drill through the hole, center, hole and blank off-centring are no more than 0.5; Car below medial surface, and control part thickness, car raised head face and chamfering; Boring through hole, and chamfering; Pulling eye; On draw folder, draw bore hole, stay the honing surplus; Car: rise plug car folder also clamps, and the car raised head face is to drawing gross thickness size, and chamfering; Mill: go up mill folder and clamping, mill bipod plane, control bipod thickness and grinding upper end are to center, hole size; In like manner, the center, hole is arrived to the figure paper size in accent face mill bipod plane and grinding upper end; Mill: on mill folder and clamp, mill out shelves to illustrated dimensions; Bore: go up drill jig and clamp, on the cylindrical of machining hole, bore, expansion, cut with scissors by figure requirements Deburring:, go by in the figure requirement bipod chamfering 0.5X45 ° Aperture and all the other all burrs; Heat treatment: carbo-nitriding, case hardness HRC59-63, effectively hardened layer 0.1-0.3; Shaping: check bipod distortion situation,, must be shaped into size as not being inconsistent with drawing; Honing: go up the mill folder, the honing endoporus is to the figure paper size, endoporus with The position degree require less than Check: above processing is checked with corresponding micrometer, slide measure, electronics height gauge, logical no-go gage, plug, hardometer, metallograph; Packing: deburring, clean, oil, pack warehouse-in.The present invention is obtaining abundant assurance aspect product symmetry, position degree and the product hardness, good product quality has prolonged service life of product greatly, has satisfied the needs of automobile industry develop rapidly.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cutaway view of structural representation;
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
In the drawings, the processing method of shifting fork of automobile parts is characterized in that; Car: get on the bus the folder and clamp big plane, drill through the hole, center, hole and blank off-centring are no more than 0.5; Car below medial surface, and control part thickness, car raised head face and chamfering; Boring through hole, and chamfering; Pulling eye; On draw folder, draw bore hole, stay the honing surplus, and guarantee and big plane verticality is no more than 0.03; Car: rise plug car folder also clamps, and the car raised head face is to drawing gross thickness size, and chamfering; Mill: go up mill folder and clamping, mill bipod plane, control bipod thickness and grinding upper end are to center, hole size; In like manner, the center, hole is arrived to the figure paper size in accent face mill bipod plane and grinding upper end; Mill: on mill folder and clamp, mill out shelves to illustrated dimensions, guarantee that symmetry is no more than 0.3; Bore: go up drill jig and clamp, on the cylindrical of machining hole, bore, expansion, cut with scissors by figure requirements The position degree is guaranteed in the hole Deburring:, go by in the figure requirement bipod chamfering 0.5X45 ° Aperture and all the other all burrs; Heat treatment: carbo-nitriding, case hardness HRC59-63, effectively hardened layer 0.1-0.3; Shaping: check bipod distortion situation,, must be shaped into size as not being inconsistent with drawing; Honing: go up the mill folder, the honing endoporus is to the figure paper size, endoporus with The position degree require less than Check: above processing is checked with corresponding micrometer, slide measure, electronics height gauge, logical no-go gage, plug, hardometer, metallograph; Packing: deburring, clean, oil, pack warehouse-in.
