Abstract

The invention relates to the technical field of machine tool main transmission mechanisms, in particular to an automatic three-gear stepless speed change main transmission system suitable for numerical control horizontal lathes and numerical control horizontal turning centers. The automatic three-gear stepless speed change main transmission system is characterized by comprising a motor device, a main transmission mechanism, a worm and gear transmission mechanism and a hydraulic gearshift, wherein the motor device comprises a main shaft servo motor; the hydraulic gearshift comprises a first oil cylinder, a second oil cylinder and a third oil cylinder which are mounted on a main shaft box body; a worm and a worm gear of the worm and gear transmission mechanism are meshed with each other; the end part of the worm is provided with a worm end bevel gear which is meshed with a second shaft end bevel gear; the main shaft box body is also provided with a coder device which is used for measuring and feeding back the rotating speed of a main shaft. The automatic three-gear stepless speed change main transmission system is respectively provided with three transmission paths of belt transmission, gear transmission and worm and gear transmission, the structure is simple, the speed adjustable range is wide, high-speed efficient finish machining is realized, and low-speed large-torque rough machining and semifinishing are also suitable.

Description

technical field [0001] The invention relates to the technical field of main transmission mechanisms of machine tools, in particular to an automatic three-speed continuously variable main transmission system suitable for a numerically controlled horizontal lathe and a numerically controlled horizontal turning center. Background technique [0002] CNC machine tools have a wide range of processes and strong process capabilities, so the main drive system is required to have a wide range of speed regulation to ensure that a more reasonable cutting amount can be selected during processing, so as to obtain the best processing quality and productivity. The main motion system of CNC machine tools in the prior art widely adopts transformation and meshing gear pairs to realize stepless transmission. The mechanical transmission structure is complicated, the speed regulation range is limited, the vibration and noise problems are prominent, and high-speed cutting cannot be realized. Cont...
