Abstract

The present invention relates to the fine-processing technique at a kind of STR knuckle crotch position, it comprises the following steps: be installed on fixture by knuckle, and the first main shaft of lathe is provided with pin-and-hole drill bit, heavy boring milling cutter, fine boring cutter, rose reamer and face cutter;Rough boring cutter, fine boring cutter and expansion boring cutter are installed on the second main shaft of lathe;On 3rd main shaft of lathe, fine boring cutter is installed, first hole is cut with pin-and-hole drill bit drilling when a station, control machine tool chief axis more accurately to move 48mm to two station and carry out the processing of two kingpin bores, first first kingpin bore of heavy boring, first kingpin bore of right boring again, then with rose reamer, the cylindrical of the first kingpin bore is carried out chamfering;While processing first kingpin bore, second kingpin bore is processed, first second kingpin bore of heavy boring, then second kingpin bore of right boring, then second kingpin bore is carried out reaming.The present invention is once installed increases pin hole processing work step, has unified positioning datum, has decreased cumulative errors, has ensured pin hole position.

Description

A kind of fine-processing technique at STR knuckle crotch position
Technical field
The invention belongs to machine tooling technical field, be specifically related to the fine-processing technique at a kind of STR knuckle crotch position.
Background technology
Knuckle is one of major part on steering axle of automobile, it is possible to make vehicle steadily travel and sensitive transmission traveling side To, the function of knuckle is subject to automotive front load, supports and drive front-wheel to rotate around stub and make motor turning.Knuckle Shape matching is complicated, has concentrated the construction features of the four class parts such as axle, set, disk ring, crotch, and knuckle is by bearing journal, flange Dish, crotch three parts form.The planform of bearing journal is multidiameter, its be structurally characterized in that by coaxial external cylindrical surface, Taper seat, flank, and the shaft shoulder, knuckle and the revolving body of end face composition vertical with axial line;Ring flange includes method Blue face, uniform connecting bolt through hole and the screwed hole of limiting steering;Crotch is the upper and lower ear by knuckle and flange face is constituted Crotch body.
At present, when processing STR knuckle, the polish at knuckle crotch position to be completed, need first milling end, reprocess two Individual kingpin bore, then simulate two kingpin bores and end face looks for the positioning datum of pin-and-hole.This kind of processing causes STR knuckle processing technique Position error add up severe deviations, the pin-and-hole on STR knuckle is the pin-and-hole that air chamber support rises orientation simultaneously, its With the efficiency of assembling that the accuracy of kingpin bore position degree directly affects vehicle, so the quality of its crudy directly affects gas The braking effect of room.
Summary of the invention
It is an object of the invention to provide the fine-processing technique at a kind of STR knuckle crotch position.The present invention is once installed Increase pin hole processing work step, unified positioning datum, decreased cumulative errors, ensured pin hole position.
The technical solution used in the present invention: the fine-processing technique at a kind of STR knuckle crotch position, it is characterised in that it Comprise the following steps: knuckle is installed on fixture, the first main shaft of lathe is provided with pin-and-hole drill bit, heavy boring milling cutter, essence Boring cutter, rose reamer and face cutter;Rough boring cutter, fine boring cutter and expansion boring cutter are installed on the second main shaft of lathe;The 3rd of lathe Fine boring cutter is installed on main shaft, first cuts hole with pin-and-hole drill bit drilling when a station, then control machine tool chief axis and accurately move 48mm Carry out the processing of two kingpin bores, first first kingpin bore of heavy boring, then first kingpin bore of right boring to two stations, then use rose reamer The cylindrical of the first kingpin bore is carried out chamfering, finally with the face cutter finish-milling large end face on the first main shaft;Process first master While pin-and-hole, second kingpin bore is processed, first second kingpin bore of heavy boring, then second kingpin bore of right boring, more right Second kingpin bore carries out reaming;After kingpin bore machines, workpiece is moved to three stations, with the fine boring cutter on the 3rd main shaft Boring and milling small end face.
Further, first kingpin bore of processing and the second kingpin bore coaxial line, and first kingpin bore and second main The axis of pin-and-hole is 4 degree with the axis angle of the prominent axle of knuckle.
Further, the centre distance of pin-and-hole and first kingpin bore is 48mm.
Further, first kingpin bore and the second kingpin bore line of centres are perpendicular to the flat of described large end face and small end face Face.
Compared with prior art it provides the benefit that the present invention: the STR knuckle crotch position of present invention processing, once fills Card increases pin hole processing work step, has unified positioning datum, has decreased cumulative errors, has ensured pin hole position;The present invention reduces Manufacturing cost, efficiency is high, low cost, Functionality, quality and appealing design.
Detailed description of the invention
The fine-processing technique at a kind of STR knuckle crotch position, it comprises the following steps: knuckle is installed on fixture On, the first main shaft of lathe is provided with pin-and-hole drill bit, heavy boring milling cutter, fine boring cutter, rose reamer and face cutter;The second of lathe Rough boring cutter, fine boring cutter and expansion boring cutter are installed on main shaft;On 3rd main shaft of lathe, fine boring cutter is installed, first uses when a station Hole is cut in pin-and-hole drill bit drilling, then controls machine tool chief axis and accurately move 48mm to two station and carry out the processing of two kingpin bores, the thickest First kingpin bore of boring, then first kingpin bore of right boring, then with rose reamer, the cylindrical of the first kingpin bore is carried out chamfering, finally use Face cutter finish-milling large end face on first main shaft;While processing first kingpin bore, second kingpin bore is processed, First second kingpin bore of heavy boring, then second kingpin bore of right boring, then second kingpin bore is carried out reaming;Kingpin bore machines After, workpiece is moved to three stations, with the fine boring cutter boring and milling small end face on the 3rd main shaft.
Wherein, first kingpin bore of processing and the second kingpin bore coaxial line, and first kingpin bore and the second kingpin bore The axis angle of prominent axle of axis and knuckle be 4 degree.The centre distance of pin-and-hole and first kingpin bore is 48mm.First Individual kingpin bore and the second kingpin bore line of centres are perpendicular to the plane of described large end face and small end face.
