Gear grinding machine and indexing compensation method for gear machining

Abstract

The invention discloses a gear grinding machine and an indexing compensation method for gear machining, the gear grinding machine comprises a lathe bed, a workpiece box, a grinding wheel box body and a Z-axis guide rail, the workpiece box, the grinding wheel box body and the Z-axis guide rail are installed on the lathe bed, the workpiece box is used for installing a gear workpiece, and the relative position between the grinding wheel box body and the workpiece box is adjustable; the grinding wheel box body can move along the Z-axis guide rail; the device is characterized in that an on-line measuring device is installed on the grinding wheel box body, the on-line measuring device comprises a probe, and the probe is used for measuring tooth pitch parameters of the gear workpiece. According to the gear grinding machine, the indexing error of the gear workpiece can be directly measured on the gear grinding machine through structural optimization, the gear workpiece does not need to be disassembled and assembled, deviation caused by different positioning is avoided, indexing error detection is relatively more accurate, and therefore the accuracy of gear indexing compensation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a gear grinding machine and an indexing compensation method for gear processing. Background technique [0002] When processing gears (such as spiral bevel gears, etc.), after heat treatment, in order to eliminate the deformation caused by heat treatment, improve the precision of the gear and improve the roughness of the tooth surface, it also needs to be processed by a gear grinding machine. [0003] Before grinding, the grinding wheel is usually trimmed to ensure that the contour of the grinding wheel is close to the ideal state. However, in the actual grinding process, with the increase of the number of grinding teeth, the grinding wheel will wear, combined with the environment such as temperature change Factors will cause the indexing error of the gear, which will easily lead to unqualified gear accuracy. [0004] During the grinding process of the gear grinding machi...

Problems solved by technology

In the actual operation of this method, the gear workpiece needs to be transported between the gear grinding machine and the measuring machine tool, which is time-consuming and laborious, and because different machines are used for processing and measurement, there is secondary positioning, which may cause deviation, resulting in detection or subsequent compensation. Into the positioning deviation during operation, thus affecting the accuracy of indexing error compensation
