Abstract

The present invention relates to gear machining equipment, and is especially numerically controlled inner tooth grinding head. The numerically controlled inner tooth grinding head consists of cutter shaft, grinding wheel installing angle regulating mechanism, grinding wheel bearing mechanism and driving force transmission mechanism. The grinding wheel installing angle regulating mechanism consists of the lower arced surface of cutter shaft and the upper arced surface of the grinding wheel support; and the driving force transmission mechanism consists of spring soft shaft and bevel gears. The present invention has the advantages of small grinding error, high grinding precision and smooth running.

Description

technical field [0001] The invention relates to a gear processing equipment, in particular to a special grinding head for internal tooth numerical control forming grinding. Background technique [0002] The shape grinding technology of disc grinding wheel is an important technology for the finishing of gears and tooth-shaped workpieces, especially the finishing of high-hardness and high-precision gears. The CNC form grinding technology can process gears and tooth-shaped workpieces with any tooth shape and any installation angle, which is the development direction of the current form grinding technology. [0003] The current domestic CNC form grinding machine tools can only grind external gears, such as the YK7332A form gear grinding machine produced by my country Qinchuan Machine Tool Group Co., Ltd. and the YK7320 six-axis CNC form gear grinding machine produced by Chongqing Machine Tool Factory, etc. The advanced technology of form grinding equipment meets the needs of CNC...
