Abstract

The invention discloses a double-end-face numerical control chamfering machine tool and method for an ultra-large internal tooth gear. The machine tool comprises a numerical control rotary table, a horizontal radial sliding table, a first stand column, a second stand column, a Y1 tool rest assembly, a Y2 tool assembly, a Y3 tool rest assembly, a Y4 tool assembly, an X1-axis radial feeding system,an X2-axis radial feeding system, a Y1-axis vertical feeding system, a Y2-axis vertical feeding system, a Y3-axis vertical feeding system, a Y4-axis vertical feeding system, a steel brush deburring system and workpiece supports. According to the double-end-face numerical control chamfering machine tool, the motion mode that a workpiece is fixed and the machine tool does rotary motion is adopted, the occupied area of the numerical control machine tool for chamfering an ultra-large gear is greatly reduced, simultaneous chamfering of the end faces of the two sides of the ultra-large internal tooth gear is achieved through a hard alloy milling tool rotating at a high speed, chamfers are adjustable in size and shape, the sizes of the chamfers are consistent, tooth grooves are automatically centered, and deburring and polishing work can be carried out on tooth roots, tooth tops and other parts. The machine tool is innovative in structure, low in manufacturing cost and high in automation degree.

Description

technical field [0001] The invention relates to a gear chamfering processing machine tool, in particular to a high-efficiency chamfering processing machine tool and method for the upper and lower end faces of super-large internal gears based on the principle of numerical control. It belongs to the field of advanced manufacturing technology. Background technique [0002] With the continuous development of my country's advanced manufacturing industry, the requirements for gear quality are also increasing, and gear chamfering is an important measure to improve gear quality. Gear chamfering can reduce the noise during gear meshing; improve meshing accuracy and reduce meshing impact; reduce stress concentration during heat treatment; increase the service life of gears. At the same time, the chamfered gear has the advantages of beautiful appearance and no burr, and it is not easy for workers to scratch their hands during assembly and debugging. [0003] At present, with the deve...
