Abstract

The invention discloses a method for machining a precision camshaft. The method comprises the steps that a cam contour track is generated according to a cam contour curve, machining parameters are set so that the practical machining route of a cam can be obtained, and then numerical control programs used for numerical control machining are obtained through post-processing; the camshaft is mounted on a numerical control machine tool, the numerical control programs are input to the numerical control machine tool, and a cam groove is formed in the outer circumferential face of the camshaft. The numerical control programs for machining the camshaft are optimized, and the cam contour track is generated according to the cam contour curve, so that the practical machining route of the cam is obtained according to the machining parameters, and the problems that the programming process is complex and the numerical control programs cannot be adjusted according to the design precision of the camshaft easily due to traditional three-dimension solid model building are solved; optimization is conducted from the link of numerical control programming to meet the requirement for the machining precision of the camshaft, and the programming process is simple and convenient to adjust.

Description

technical field [0001] The invention relates to the field of digital processing control, in particular to a precision camshaft processing method. Background technique [0002] The cam mechanism plays a huge role in various industries because of its simple structure, compact structure, and the ability to realize any expected movement of the follower. It is also widely used in aero-engines. In order to achieve the expected motion accuracy and service life of the follower, the surface accuracy requirements of the aero-engine camshaft are getting higher and higher, and the surface profile is 0.005mm. Ordinary equipment can no longer meet this accuracy requirement. However, the technology of processing high-precision cam surfaces using the current processing methods is still not mature enough and is still in the exploration stage. The 0.005mm profile and Ra0.8 roughness requirements of the camshaft have not been guaranteed. [0003] Camshaft machining is a process of simultaneou...
