Embodiment

[0025] Example: such as Figure 1 to 8 As shown, the machining process of the camshaft of the present invention includes the following steps:

[0026] A. Blanking, according to two finished products for each blank, the length of the selected blank is 82mm, the diameter is 30mm, and the material is 42CrMo;

[0027] B. CNC lathe rough machining of the blank, the outer circle of the rough turning, the diameter of the outer circle is 28.5mm, the end face of the blank is flat, and the eccentric circle is processed; according to the eccentric center distance of the cam, the two ends of the blank are drilled with center holes, which are divided into upper, The lower center hole, the center distance is 6.5mm; CNC lathe roughing, the upper center hole is positioned, the eccentric circle in the middle of the car, its diameter reaches 21.5mm; the CNC lathe roughing, the lower center hole is positioned, the eccentric circle at both ends of the car, its The diameter reaches 18.5mm; the thickne...

Abstract

The invention belongs to the field of machine part machining, and particularly relates to a processing technology of a camshaft. The processing technology of the camshaft comprises the step A of blanking according to the standard that two finished products are blanked from each work-blank; the step B of carrying out rough machining, rough turning and end face flattening on the work-blank and machining eccentric circles through a numerically controlled lathe; the step C of thermal refining and enabling the rigid to be 26-31 HRC; the step D of carrying out half finish turning on the work-blank through the numerically controlled lathe; the step E of carrying out accurate grinding on the work-blank through a cylindrical grinding machine; the step F of carrying out linear cutting on the work-blank for forming two same products; the step G of carrying out flat facing through the numerically controlled lathe; the step H of carrying out punching through a machining center and carrying out punching and chamfering on the two products; and the step I of thermal treating. The processing technology of the camshaft is simple, the two products can be machined at the same time, and therefore the producing and machining cost is saved greatly, the production efficiency is improved, the processing technology is flexible, and the universality is good.

Description

Technical field [0001] The invention belongs to the field of mechanical parts processing, in particular to a camshaft processing technology. Background technique [0002] Most of the machining processes for camshafts in the prior art are cumbersome and complicated, and can only be processed for one camshaft product, which has poor versatility, high use cost, and high production cost, and cannot meet the needs of production and processing. Summary of the invention [0003] 1. Technical problems to be solved [0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art, and provide a camshaft machining process, which effectively solves the prior art machining process for camshafts, which is cumbersome and complex, and has low machining efficiency. Use cost, high production cost defects. [0005] 2. Technical solution [0006] In order to solve the above technical problems, the present invention provides a camshaft machining process, ...
