Abstract

The invention provides a method for processing an interlock fork of automobile parts, which comprises the following steps: according to requirements of a drawing, milling a bottom surface to ensure a distance to a hole center, milling an inner opening on the bottom surface, milling teeth on the inner opening, and making the periphery of the chamfered teeth be 1*45 degrees; positioning in the tooth form, pressing a workpiece, and boring a large hole to a size in the drawing; milling the length and height of the inner opening to sizes in the drawing; milling two end faces of a small hole, boring and enlarging the small hole to the size in the drawing, and chamfering; performing quenching, namely, performing induction quenching on the inner opening and the surfaces of the teeth, and making the surface hardness not less than HRC56; and inspecting the processing with corresponding height gauge, vernier caliper, go/no-go gauge, hardmeter and metalloscope. The method guarantees the position, the symmetry and the verticality of products, and good product quality, greatly prolongs the service life of the products, and increases enterprise benefit.

Description

The processing method of interlock fork of automobile parts

Technical field:

The present invention relates to auto parts machinery, particularly relate to the processing method of interlock fork of automobile parts.

Background technology:

Position degree, symmetry, the perpendicularity of present interlock fork of automobile parts product can not get guaranteeing, poor product quality, and service life is short, brings very big loss to enterprise and society.

Summary of the invention:

The object of the invention is exactly the processing method that a kind of interlock fork of automobile parts will be provided, and it can overcome the existing problem of above product well.The objective of the invention is to realize like this, the processing method of interlock fork of automobile parts is characterized in that: mill: locate with blanking inner hole; Workpiece pressing, milling bottom surface is guaranteed the centre distance to the hole; The milling bottom surface internal arm is guaranteed symmetry 0.2mm, with height gauge, slide measure check; Mill teeth on the internal arm of bottom surface is guaranteed symmetry 0.5mm, and 1X45 ° all around of pawl shape checked with slide measure; With the profile of tooth location, workpiece pressing, boring upper left side macropore are guaranteed position degree 0.2mm to size, and chamfering 1X45 °, with slide measure, logical no-go gage check; Mill internal arm length and height to scheming paper size, guarantee that perpendicularity is no more than 0.04; Mill upper right side aperture both ends of the surface, boring, expansion aperture are to size, and chamfering, with slide measure, logical no-go gage check; Quench: at internal arm and tooth surface impewdance matching, case hardness is not less than HRC56, with hardometer, metallographic microscope check.The position degree of product of the present invention, symmetry, perpendicularity are guaranteed, and good product quality has prolonged service life widely, has increased the performance of enterprises.

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:

Below in conjunction with accompanying drawing the present invention is described further: in the drawings, the processing method of interlock fork of automobile parts is characterized in that: mill: locate with blanking inner hole; Workpiece pressing; Milling bottom surface is guaranteed the centre distance to the hole, the milling bottom surface internal arm; Guarantee symmetry 0.2mm, with height gauge, slide measure check; Mill teeth on the internal arm of bottom surface is guaranteed symmetry 0.5mm, and 1X45 ° all around of pawl shape checked with slide measure; With the profile of tooth location, workpiece pressing, boring upper left side macropore are guaranteed position degree 0.2mm to size, and chamfering 1X45 °, with slide measure, logical no-go gage check; Mill internal arm length and height to scheming paper size, guarantee that perpendicularity is no more than 0.04; Mill upper right side aperture both ends of the surface, boring, expansion aperture are to size, and chamfering, with slide measure, logical no-go gage check; Quench: at internal arm and tooth surface impewdance matching, case hardness is not less than HRC56, with hardometer, metallographic microscope check.
