[0002] In the field of transmission shaft manufacturing and processing technology, Huajian shaft is a general-purpose component widely used in the connection between various transmission shafts. Traditional manufacturing processes mostly use gear hobbing machines for rough machining and then fine grinding. Due to the accuracy of gear hobbing machines and The efficiency cannot meet the needs of the spline shaft technology level, resulting in low production and processing efficiency, high cost, and difficulty in mass production of the spline shaft

[0003] The existing CNC spline shaft milling machine is generally refitted on an ordinary mechanical milling machine, and the ordinary motor on the mechanical milling machine is replaced with a servo motor or a stepping motor, and the transmission chain of each axis is still driven by mechanical components such as gears, so Its processing accuracy is not improved, but it only reduces labor intensity and improves production efficiency; in the existing CNC spline shaft milling machine, some shafts are driven by servo motors, although the transmission of mechanical components such as multi-stage gears in the transmission chain of each shaft is somewhat different. Simplified, but more mechanical transmissions are still used, which still cannot completely eliminate the influence of cumulative errors and indexing errors; mechanical transmissions have large transmission errors, low transmission accuracy, slow processing speed, high equipment failure rate, and complicated maintenance

The machining accuracy of the spline shaft determines the function of the drive shaft, which not only affects the use and wear of the spline shaft itself, but also affects the service life and wear of the drive shaft
