Machining method of worm by milling instead of turning and implementation device thereof

Abstract

The invention discloses a machining method of a worm by milling instead of turning and an implementation device thereof, wherein a numerically-controlled machine is adopted to assemble and fix a worm blank to be machined, and the worm blank is driven to respectively do program-controlled displacements in a two-dimensional plane where a central shaft is located along the extending axial direction of the central shaft and the axial direction vertical to the central shaft through program control, and further, do program-controlled autorotation along the one-dimensional axial direction of the central shaft; meanwhile, the program-controlled telescopic adjustment relative to the surface of the worm blank of a milling cutter is adopted to carry out milling machining in a fourth-dimension axial direction vertical to the two-dimensional plane; and the driving on the fourth-dimension axial direction is controlled through a numerically-controlled machine controller, so as to realize the full-automatic machining of the worm. Compared with the traditional machining manner, the processing hour for machining the worm is obviously shortened, the efficiency and the quality for machining are improved, meanwhile, the dependence on technicians and the labor operating intensity of workers are lowered, so that the machining method of the worm by milling instead of turning and the implementation device thereof are more focused on holding the pass of the quality of a finished product. In addition, the implementation conditions of the machining method which uses milling instead of turning are mature, thus, the method is easy to be popularized.

Description

technical field [0001] The invention relates to a fully automatic processing method of a worm, in particular to a program-controlled milling processing method of a worm and an implementing device thereof. Background technique [0002] The worm is a transmission mechanism that meshes with a worm wheel or a helical gear and is used to transmit motion or force. It is often used to transmit motion and force between two staggered shafts. A large transmission ratio can be obtained, and it is more compact than a cross-axis helical gear mechanism. The meshing tooth surfaces of the two wheels are in line contact, and its load capacity is much higher than that of the crossed-axis helical gear mechanism; the worm drive is equivalent to the screw drive, which is a multi-teeth meshing drive, so the transmission is stable, the noise is small, and it has self-locking properties; when the worm When the lead angle is smaller than the equivalent friction angle between the meshing gear teeth,...
