Modification method for involute spline relief grinding wheel

Abstract

The invention discloses a modification method for an involute spline relief grinding wheel. The method comprises the specific steps that 1, spline parameters are set on a control panel, and the contour shape of the grinding wheel is automatically fitted according to the given spline parameters; 2, the to-be-modified part of the fitted contour of the grinding wheel is selected, and therefore whether the diamond grinding wheel needs to be locally modified or wholly modified is determined; 3, after the contour of the grinding wheel is selected, the control panel is clicked to generate a G code, the generated G code is stored in a TXT text; 4, a numerical control grinding machine is powered on and turned on, the TXT text storing the G code is transmitted into a controller of a numerical control grinding machine, and the controller can automatically recognize and load the TXT text which is transmitted just, and the G code is read. Corresponding parameter values are given for different reference diameters and pressure angles within different ranges for calculation of involute start circles, and the precision of the fitted grinding contour is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for modifying an involute spline relief grinding wheel. Background technique [0002] Spline shafts are divided into two types: rectangular spline shafts and involute spline shafts. Among them, involute spline shafts are used for links with large loads, high centering accuracy requirements, and large sizes. It can play an important role and performance in a certain industry. It is produced and processed according to the principles and working procedures to ensure that it can play an important role in production. Its characteristics: multi-tooth work, high bearing capacity, good neutrality, and guiding Well, the tooth root is thicker, the stress concentration is small, the strength of the shaft and the hub is small, the processing is convenient, and the grinding method can be used to obtain higher precision. [0003] The involute spline shafts currently use...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a modification method for involute spline shovel grinding wheel, which adopts the form of library, and provides corresponding parameter values ​​for the diameter of the pitch circle and the size of the pressure angle in different ranges , used to calculate the diameter of the involute starting circle, thereby calculating the coordinates of the involute starting point, solving the problem that the generated graphics after inputting parameters are fixed, and cannot be manually modified in the graphics, let alone after manual modification Generate the corresponding G code, which makes the finished product bring a lot of inconvenience to the subsequent use
