摘要
环面蜗杆加工的低精度和低效率问题,成为制约环面蜗杆发展的主要因素。针对精密磨削平面包络环面蜗杆和锥面包络环面蜗杆,运用虚拟中心距加工原理,研发了七轴四联动数控环面蜗杆磨床。工件在机床上只需一次装夹即可自动完成左右齿面的磨削。操作者不需要手动编程,只需在磨削软件中输入工件参数,即可自动生成加工程序。在研制的数控环面蜗杆磨床上进行平面包络环面蜗杆的试切实验,结果表明研制方案可行、精度可达预期要求。
The low precision and low efficiency of the machining are the main factors that restrict the development of the hourglass worm. Aiming at precision grinding planar enveloping hourglass worm and the conical surface enveloping hourglass worm, using virtual center distance principle, a seven axis four linkage CNC hourglass worm grinding machine was developed. The left and the right tooth surface grinding of the workpiece was completed automatically with a single chucking. The operator did not need manual programming, the processing procedure could automatically generated once input the workpieee parameters in the grinding software. Cuttingexperiments of planar enveloping hourglass worm was processed on the CNC worm grinding machine. The results show that the modification is feasible and the precision is up to expectations.
