Description

Cutter setting device of forming wheel gear grinding machine Technical Field The application relates to the field of gear grinding machines, in particular to a cutter setting device of a forming wheel gear grinding machine. Background The numerical control gear grinding machine uses a grinding wheel as a grinding tool to process tooth surfaces of cylindrical gears or certain gear processing cutters, is mainly used for eliminating deformation after heat treatment, improves gear precision, improves tool setting precision and efficiency of the gear grinding machine, and has important significance for improving gear processing precision and efficiency. The automatic tool setting of the gear grinding machine can realize the adjustment of tool setting without stopping the machine, has the advantages of simple operation, high efficiency, high tool setting precision and the like, and the main idea of the automatic tool setting is that a numerical control system automatically acquires tooth slot boundaries at two sides of a workpiece and records the positions of the tooth slot boundaries, then calculates the accurate midpoint position of the tooth slot, namely the starting point of feeding processing, and finally sends an instruction to determine the position of a grinding wheel by a servo system. Therefore, how to quickly and accurately acquire the tooth slot boundary position is the key of the automatic accurate tool setting technology.
