Automatic secondary tool setting method based on numerically-controlled gear hobbing machine

Abstract

The invention discloses an automatic secondary tool setting method based on a numerically-controlled gear hobbing machine and relates to the technical field of the automatic secondary tool setting method based on the numerically-controlled gear hobbing machine. The automatic secondary tool setting method based on the numerically-controlled gear hobbing machine comprises the following steps of a, adopting different specifications of sensors to perform data measurement and acquisition to each tooth of measured gears different in modulus and gear number; b, establishing a measurement mathematic model based on acquired data through measurement and the tooth number of the measured gears; c, using adopted sensors and the measured gears as objects and testing sensor measurement data through experiments according to the established measurement mathematic model to confirm an amplifier setting parameter; d, setting an compensation angle according to a cutting adjustment result of a first workpiece, changing an offset parameter of a workpiece installing shaft according to the compensation angle to finish automatic compensation and finishing automatic secondary tool setting adjustment after cutting adjustment of the first workpiece is qualified. The automatic secondary tool setting method is simple in operation, can achieve secondary tool setting automatically and is not limited by production experiences of workers, and the accuracy and the efficiency are improved remarkably.

Description

[0001] Technical field [0002] The invention involves the secondary knife technical field of CNC machine tools. Background technique [0003] CNC roller machine is a machine tool that processs the gear according to the exhibition.Two -time knife is the gear parts after coarse or semi -essence processing, separated from the machine tool for quenching or other processes.The gear after quenching or other processes is re -mounted for fine processing. At this time, the rolling knife and the workpiece must be aligned (the roller teeth are consistent with the altitude of the processed parts), that is, the second -time knife.Two -time knife is one of the complex process preparations in rolling tooth processing. [0004] The second -time knife operation of the traditional roller machine is based on the production experience, and it is determined by visual inspection method to determine the opposite of the rolling knife and the processed workpiece.The specific method is to scrape the wor...
