Description
Technical field
The present invention relates to machine components production method technical field, the processing method particularly relating to a kind of selector fork.
Background technology
Some auxiliary components commonly used in the vehicles and plant equipment, its shape many less rule, selector fork
It is exactly one common in this kind of part, due to particularity and the importance of serviceability thereof of its shape, thus adds it
The difficulty of forging molding, is required for careful consideration in the distribution of material and the selection of technique.In general due to the processing of plane
Precision is easier to ensure that than the machining accuracy in hole, and therefore, the design follows the principle of first face metapore, and adding hole and plane
Work is clearly divided into roughing and finishing stage to ensure the machining accuracy in hole.When formulating technological procedure, the most first machined surface,
Processing other on the basis of face again, the whole course of processing selects building-block machine, and the most each operation fixture all uses special fixture,
Particularly in the operations such as processing big end hole, select the location mode of plane and two pits, and clamping force required for considering is less etc.
Factor.
Summary of the invention
The purpose of the present invention is contemplated to overcome the defect of traditional handicraft forging molding difficulty, devises a kind of selector fork
Processing method, efficiency is high, and blank internal stress is little, and molding is convenient, and precision is high, non-cutting time and to prepare finish time short.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
The processing method of a kind of selector fork, comprises the steps:
S1, selection cast steel material cast blank；
S2, turning shift fork end surface, bore, expand Φ 15H8 hole, orifice chamfer；
S3, correction shift fork foot；
S4, rough mill shift fork foot both ends of the surface；
S5, milling shift fork foot medial surface；
S6, deburring；
S7, shift fork foot selective hardening；
S8, correction shift fork foot；
S9, mill shift fork foot both ends of the surface；
S10, cleaning；
S11, inspection.
In described step 1, cast blank uses metal pattern sand mold machine to carry out cast form, with the sub-module design of band core,
Dimensional tolerance of casting grade takes 9 grades, normalized treatment hardness 174～207HBS, and pattern draft is for taking 30 °.
Φ 15H8 hole and end face in described step 1 use back wheeled capstan lathe and special fixture to process at a machine tool
On complete.
Rough milling shift fork foot both ends of the surface in described step 4, monolateral surplus takes 3.2mm, and surface roughness takes 12.5 μm.
Described step 5 milling shift fork foot medial surface, monolateral surplus takes 3.5mm, and surface roughness takes 12.5 μm.
Described step 9 grinds shift fork foot both ends of the surface, and monolateral surplus takes 0.3mm, and surface roughness takes 6.3 μm.
Owing to have employed above technical scheme, present invention have the advantage that
The processing method of selector fork disclosed in this invention, the symmetry of selector fork, position error are little, can more than one piece
Pouring into a mould, efficiency is high, and blank is precision castings, and internal stress is little simultaneously, and molding is convenient, and process route is short, decreases clamping workpiece number of times,
Being prone to ensure the relative-position error of machined surface, the lathe quantity of needs is few, reduces the workpiece transport at inter process, reduces auxiliary
Time and preparation finish time.
Accompanying drawing explanation
Fig. 1 is selector fork structural representation of the present invention；
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
The processing method of a kind of selector fork, comprises the steps:
