Yc7150 Grinding Machine Cnc Transformation

Based on the study of the YC7150 gear grinding machine, this paper analyses the transmission principle of high accuracy gear processing equipment, gives a detailed analysis of the advantages and disadvantages of worm-and-wheel driving gear grinding machine and base circle dish generating gear grinding machine, and on the most economical condition, raises a point that processing high accuracy gear should select base circle dish generating principle. In the light of many problems existing in the YC7150 gear grinding machine on hand in the course of actual use, such as the weak dividing precision maintainable quality, the large gear accumulative pitch error, the low profile precision, it puts forward CNC transform scheme on this equipment. In the process of the specific transformation, in aspect of mechanism, original indexing mechanism' s dividing claw is cancelled and stepping motor driving is applied. In aspect of hardware, STD 5081 multifunction CPU and 8088 chip as microprocessor are utilized. In aspect of software, a algorithm about high precision graduation by CNC is studied and assemble language exploiting application program is used, which has the advantages of occupying less internal space with faster transaction speed. At the same time, under the pattern of supervision, the application program can be carried out by EPROM fixed, which is very advantageous to awful industry locale environment.
