Gear cutter hob sharpening machine with adjustable sharpening angle

Abstract

The invention discloses a gear cutter hob sharpening machine with an adjustable sharpening angle. The gear cutter hob sharpening machine with the adjustable sharpening angle includes a base plate, support legs and a working table. The upper end face of the working table is provided with a clamping device and a sharpening device. The sharpening device includes a grinding machine and a moving mechanism for installing the grinding machine. A rotating seat is arranged on the moving mechanism. The upper end face of the rotating seat is provided with a stepped hole with small diameter at the upper end and large diameter at the lower end. The stepped hole is internally provided with a stepped rotating shaft matched with the stepped hole. The upper end face of the rotating seat is provided with athreaded through hole leading to the stepped hole. The threaded through hole is provide with a fourth fixed bolt. The upper end of the stepped rotating shaft extends to the position above the rotatingseat. The grinding machine is arranged at the upper end of the stepped rotating shaft. According to the gear cutter hob sharpening machine with the adjustable sharpening angle, the angle between a center axis of a grinding wheel and a center axis of a hobbing cutter can be adjusted, the problem that the angle between the center axis of the grinding wheel and the center axis of the hobbing cutterof an existing gear cutter hob sharpening device cannot be adjusted is solved, and the grinding effect on the hobbing cutter is enhanced.

Description

technical field [0001] The invention relates to the field of gear hob grinding devices, in particular to a gear hob grinding machine with adjustable grinding angle. Background technique [0002] A gear hob, also known as a hobbing cutter, is a precision tool for machining gears according to the generation method. The blade of the gear hob will be worn and blunt during the process of processing the gear. After blunting, it is necessary to use the gear hob grinding device to grind the gear hob. [0003] The Chinese utility model patent with the publication number CN207788451U discloses a grinding device for gear hobbing cutters, including a grinding machine, a device platform and a hob installation structure for installing hob cutters to be ground on the device platform , the hob installation structure is formed by the hob installation shaft perpendicular to the rotation axis of the grinder, the hob installation shaft has an overhang end for the hob set to be ground; the devi...
