Abstract
A machining method for a shifting fork differential between wheels of a heavy-duty car comprises the following steps that (1) a 45# forging blank is adopted; (2) turning is carried out; (3) plane milling is carried out; (4) a start gear is milled; (5) the upper overlapping curve face of the lower end face B is milled; (6) the top face is milled; (7) high-frequency quenching is carried out on the obverse side and the reverse side of the two overlapping curve faces; (8) products are detected and put into a storage. The machining method has the advantages of being high in production efficiency and machining accuracy, low in machining cost and the like.
Description
Technical field：
The present invention relates between a kind of processing method of auto parts machinery, more particularly to a kind of heavy-duty car wheel shift fork differential plus
Work method.
Technical background：
Shift fork differential between automotive wheels, is the strength member of differential lock, and shift fork differential slidably engages set, makes engagement for manipulation
Set axially-movable, by ventilating and dying in cylinder, promotion slidably engage set with fixed engagement cover engagement with separate, so as to
Realize the locking and differential function of differential lock.The dimensional tolerance precision and form and position tolerance precision of shift fork differential can produce weight to traveling
The impact wanted.Once the crudy of the part cannot be guaranteed, poor product quality, service life is short, will seriously jeopardize driving
Safety, can bring very big loss to enterprise and society.
The content of the invention：
It is an object of the invention to provide between a kind of heavy-duty car wheel shift fork differential processing method, to ensure that shift fork differential adds
Work precision conforms to requirement.
The object of the present invention is achieved like this：A kind of processing method of shift fork differential between heavy-duty car wheel, its feature exists
In：Comprise the following steps：1）, using 45# rough forgings；2）, turning：So that blank is cylindrical and upper surface A positioning on lathe, school
Just clamping workpiece afterwards, car upper surface B and boring endoporus, chamfering simultaneously cut with scissors endoporus to drawing size, and control endoporus center is cylindrical with blank
Center offset；With endoporus and upper surface B locating clip clamping of workpieces, car upper surface A and chamfering are to drawing size for u-turn；3）Milling is put down
Face：With endoporus, upper surface A locating clip clamping of workpieces on milling machine, milling lower surface B to drawing size controls lower surface B with endoporus
Perpendicularity；Tune face positions milling lower surface A to drawing size with endoporus, upper surface B；4）, milling open shelves：With Internal hole positioning, shelves are opened in milling
To drawing size, the position error of shelves and internal arm is opened in control；5）, reticulate patterned surface on the B of milling lower surface：With upper surface A locating clips
Clamping of workpieces, upper two reticulate patterned surfaces of milling lower surface B；6）, milling top surface：With endoporus locating clip clamping of workpieces, milling top surface is to drawing size；
7）, high-frequency quenching：Two reticulate patterned surface tow sides are carried out with high-frequency quenching, quenching hardness is 52 ~ 56HRC, the layer depth 1 that quenches ~
3mm；8）, inspection warehouse-in.
The present invention has production efficiency high, and machining accuracy is high, the low advantage of processing cost.
Description of the drawings：
In order that present disclosure is easier to be clearly understood, below according to specific embodiment and accompanying drawing is combined, it is right
The present invention is described in further detail：
Fig. 1 is the front view in the present invention in design of part schematic diagram.
Fig. 2 is the A-A sectional views of Fig. 1.
