Embodiment Construction
[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0009] As shown in Fig. 1 and Fig. 2, a kind of manufacturing method of auto parts is characterized in that: milling: positioning with the inner hole of the blank, pressing the workpiece, milling the bottom surface, ensuring the distance to the center of the hole, opening the gear in the milling bottom surface, ensuring The symmetry is 0.2mm, check with a height gauge and vernier caliper; mill the teeth on the bottom surface to ensure the symmetry of 0.5mm, the inverted tooth shape is 1X45°, check with a vernier caliper; use the tooth shape to position, press the workpiece, and bore the upper left Make sure the position is 0.2mm from the large hole, and chamfer 1X45°, check with vernier calipers and go-no-go gauges; mill the length and height of the inner opening to the size of the drawing, and ensure that the verticality does not exce...

The invention discloses a manufacturing method of automobile parts. The manufacturing method is characterized by comprising the steps of milling the bottom surface, ensuring the distance to the centerof a hole, the opening length in the milling bottom surface and the height to the drawing size, ensuring the symmetry degree to be 0.2 and the perpendicularity not to exceed 0.04, and checking with aheight ruler and a vernier caliper; milling teeth on the inner gear of the bottom surface, ensuring the symmetry degree to be 0.5 and the peripheries of the inverted tooth shape to be 1X45 degrees, and checking with the vernier caliper; positioning with the tooth shape, pressing a workpiece, boring a large hole to the size of a drawing, ensuring the position degree to be 0.2, chamfering 1X45 degrees, and checking with the vernier caliper and a check gauge; milling the two end surfaces of a small hole according to drawing requirements, boring and expanding the small hole to the size of the drawing, chamfering, and checking with the vernier caliper and the check gauge; and quenching, specifically, the internal gear and the tooth surface are induction hardened, the surface hardness is not less than HRC56, and checking is carried out by a hardness gauge and a metallographic microscope. The automobile parts manufactured by the method are more accurate in size and better guaranteed in quality.
Description
technical field [0001] The invention relates to a method for manufacturing parts, in particular to a method for manufacturing auto parts. Background technique [0002] The position, symmetry and verticality of the current interlocking fork products of auto parts cannot be guaranteed, the product quality is poor, and the service life is short, which brings great losses to enterprises and society. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing auto parts, the size of the auto parts manufactured by the method is more accurate, and the quality can be guaranteed. [0004] To solve this technical problem, the technical solution of the present invention is: a manufacturing method of auto parts, characterized in that: milling: position with the inner hole of the blank, press the workpiece, mill the bottom surface, ensure the distance to the center of the hole, mill the bottom surface Open the...
