Abstract

The invention relates to a NC machine tool for machining large-scale curve bevel gear, characterized in that the machine body is set in T-shape in horizontal direction and the workpeice shaft is changed into vertical placement; tool seat, which can adjust space attitude, is used to adjust the angle among the machine spindle, cutting tool and workpeice to realize the machining for large-scale curve bevel gear. The invention solves problems that when prior machine tool is used to machine large-scale curve bevel gear difficulties of installing, clamping, locating and aligning exists; rigidity and stability of machine tool is lack; the machining accuracy can not be improved; the machine tool is provided with big space dimension, heavy weight and difficult manufacture. The machine tool in invention is characterized in that it have X, Y, Z, A, B, C, W moving axes; it can realize seven-axis six linkage control or seven-axis seven linkage control under the control of computer; the workpeice on the machine tool is set smoothly; installing and aligning are convenient; the machine tool with big machine rigidity and good stability can improve gear processing accuracy; it is provided with compact machine structure and small occupied area to conquer defects of prior machine tool.

Description

technical field [0001] The invention belongs to a numerical control machine tool for gear processing, in particular to a numerical control processing machine tool for processing large curved bevel gears. Background technique [0002] In the existing curved bevel gear processing technology, whether it is processing arc bevel gears or cycloidal bevel gears, CNC machining machines mostly adopt the structure shown in Figure 1, which is characterized by the A-axis of the workpiece rotation axis on the workpiece box Placed horizontally, and the workpiece box can swing around the B-axis to adjust the relative angle between the A-axis and the C-axis of the tool spindle; the C-axis is set on the Y-axis slide table, and the X-axis slide table and Y-axis slide table drive the C-axis to realize gear processing The required plane movement of the tool, the tool rotates around the C axis to realize the main cutting motion of the tool required for gear processing; the workpiece rotates arou...
