Spline broach lifting tailstock grinding process

Abstract

The invention discloses a spline broach lifting tailstock grinding process which comprises a part body, a part tooth profile, a machined surface and a broach tooth profile. When the part body is machined, the broach tooth profile is lifted to be subjected to surface treatment according to the use condition, the tail of a broach is lifted, a new tooth profile is designed, and therefore when the broach is placed flat for use, the tooth tip of each tooth falls on the part theoretical tooth profile line. By calculating the process size before machining, the machining precision is greatly improved, the machining quality is improved, and the problems that in the machining process, severe friction occurs between the broach tooth profile surface and the machined surface of the part, the quality of the machined surface becomes poor, the diameter of the broach becomes larger and larger along with advancing of the broach, the machined surface is increased tooth by tooth, friction is increasingly severe, squeal and vibration occur, galling, scaling, tearing and other defects occur to the machined surface, and the broach can be broken or a machine tool can be jammed when the defects are severe are solved.

Description

technical field [0001] The invention relates to the technical field of spline processing, in particular to a spline broach raising tailstock grinding process. Background technique [0002] Spline broaches include three tooth shapes: rectangular spline, triangular spline, and involute spline. Most of the broaches adopt layered cutting. If the tooth shape of the broach is made to be the same During the broaching process, there will be severe friction between the tooth profile surface of the broach and the machined surface of the part, which will deteriorate the quality of the machined surface. As it gets bigger, the machined surface will increase tooth by tooth, and the friction will become more and more intense, and there will be screams, vibrations, defects such as roughness, scales, and tears on the machined surface. In severe cases, the broach will break or the machine tool will break. Stuck. [0003] The current technology is to first grind the tooth shape of the broach...
