Linear cutting machining method for inner tooth spline secondary clamping

Abstract

The invention discloses a linear cutting machining method for inner tooth spline secondary clamping, and relates to the field of machining, in particular to the linear cutting machining method for inner tooth spline secondary clamping. The method comprises the following steps that a bench worker conducts lineation, an integral tooth is selected, and the center line of the tooth crest arc is drawnon the tooth end face; a workpiece is arranged on a machine tool, the end face level is aligned, the end jump value is smaller than 0.02 mm, the drawn center line of the tooth crest arc and the Y direction of the machine tool are consistent as much as possible, and fixing is conducted; plotting and programming are conducted, the programmed feed line is determined at the middle point of the tooth crest arc and coincides with the Y axis, and sorting is conducted in the clockwise direction; and the alignment function in the contact perception function is utilized, and the circle center of a non-machined part is found. Then, the Y direction is sensed, the motion function is utilized, the tooth crest circle radius is moved towards the circle center direction, and if the circle center is consistent with the circle center of a non-cut part, the circle center is determined. By means of the linear cutting machining method, coincidence between an original tooth profile and a programmed tooth profile is well achieved, the correction process is simple, and the machining precision of the workpiece can be guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a wire cutting processing method for secondary clamping of internal tooth splines. Background technique [0002] The internal tooth spline is widely used in the mechanical field, and in the process of processing the part by the wire cutting machine, sometimes a part of the part has been processed, how to ensure the cutting in the secondary clamping The route is consistent with the size and shape of the processed part, and it is completely processed under the condition of ensuring the technical requirements of the part. After the second clamping, the processing is continued due to certain changes in the positioning, and the processing accuracy of the workpiece may not be up to date. Requirements affect the processing quality. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a wire-cutting process for internal ...
