Description
Technical field:
The present invention relates to a kind of processing method of auto parts machinery, particularly relate to the processing method of shift fork differential between a kind of heavy-duty car wheel.
Technical background:
Shift fork differential between automotive wheels is the strength member of differential lock, and shift fork differential is for handling slip engaging sleeve, make engaging sleeve axially-movable, by ventilation in cylinder and die, promote engagement that slip engaging sleeve and fixed engagement overlap and be separated, thus realize locking and the differential function of differential lock.Dimensional tolerance precision and the form and position tolerance precision of shift fork differential can produce important impact to traveling.Once the crudy of this part can not be guaranteed, poor product quality, service life is short, seriously will jeopardize traffic safety, brings very large loss can to enterprise and society.
Summary of the invention:
The object of this invention is to provide the processing method of shift fork differential between a kind of heavy-duty car wheel, to ensure that shift fork differential machining accuracy conforms to requirement.
The object of the present invention is achieved like this: the processing method of shift fork differential between a kind of heavy-duty car wheel, is characterized in that: comprise the following steps: 1), adopt 45# rough forging; 2), turning: locate with blank cylindrical and upper surface A on lathe, clamping work pieces after correcting, car upper surface B and boring endoporus, chamfering cut with scissors endoporus to figure paper size, control endoporus center and blank cylindrical center offset; Tune is with endoporus and upper surface B locating clip clamping of workpieces, and car upper surface A and chamfering are to figure paper size; 3) milling flat: with endoporus, upper surface A locating clip clamping of workpieces on milling machine, milling lower surface B to figure paper size, controls the perpendicularity of lower surface B and endoporus; Milling lower surface A to figure paper size is located with endoporus, upper surface B in tune face; 4), shelves are opened in milling: with Internal hole positioning, milling opens shelves to figure paper size, controls the position error opening shelves and internal arm; 5), reticulate patterned surface on the B of milling lower surface: with upper surface A locating clip clamping of workpieces, upper two reticulate patterned surfaces of milling lower surface B; 6), milling end face: with endoporus locating clip clamping of workpieces, milling end face is to figure paper size; 7), high-frequency quenching: carry out high-frequency quenching to two reticulate patterned surface tow sides, quenching hardness is 52 ~ 56, quenching layer depth 1 ~ 3mm; 8), inspection warehouse-in.
The advantages such as it is high that the present invention has production efficiency, and machining accuracy is high, and processing cost is low.
