Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the drawings and embodiments:

[0024] First introduce the working method. The first key problem that hinders the application of forming tooth grinding is that the diamond pen needs to be blunt by the grinding wheel during use. Because the diamond pen is a brittle material, the bluntness of the diamond nib is irregular, as shown in Figure 1. , It sometimes gradually grinds from the sharp point 21 to the arc 22. At this time, it is reflected on the gear as the length of the common normal increases; sometimes it drops to 23, which makes the highest point of the nib deviate from the center point of the diamond pen and become a multi-pointed point. At this time, when the point on the left side of the diamond nib is working, the grinding wheel is repaired to shorten the involute, and when the point on the right is working, the repaired point is to extend the involute. In most cases, it is a combination of ...

Abstract

The grinding wheel dresser for gear grinding consists of a numerically controlled X-coordinate module, a numerically controlled Y-coordinate module, a numerically controlled Z-coordinate module, a numerically controlled rotating module, a diamond pen installing module and a diamond pen. The diamond pen installing module consists of a proximating numerically controlled rotating module and a compensating numerically controlled rotating module, and the diamond pen is mounted vertically on the compensating numerically controlled rotating module axis. During the trimming, the numerically controlling device simulates and drives the numerically controlled modules to ensure the diamond pen axis always perpendicular to the curved grinding wheel surface so as to trim grinding wheel tooth form with very high precision.

Description

Technical field [0001] The invention relates to gear and tooth-shaped workpiece processing equipment and technology, in particular to a shaping grinding wheel corrector for gear grinding processing. Background technique [0002] In gear grinding technology, there are generative grinding methods based on conical grinding wheels, generative grinding methods based on worm grinding wheels, generative grinding methods based on large flat grinding wheels, and forming grinding methods. Among them, the most widely used is the first. Two or two. [0003] The forming gear grinding technology requires that the disc-shaped grinding wheel be trimmed into the required profile for the next process. The forming gear grinding process can process gears and tooth-shaped workpieces with any tooth shape and any installation angle. Grinding wheel forming gear grinding technology is an important technology for the finishing of gears and tooth profile workpieces, especially high-hardness and high-precis...
