Abstract

The invention provides a numerical control gear hobbing machine. The numerical control gear hobbing machine comprises a gear core shaft, a rotating top frame, a knife rest, a knife rest sliding plateand a cooling mode controller, wherein the rotating top frame and the gear core shaft are arranged up and down, the rotating top frame is aligned with the axial center line of the gear core shaft, a contact type temperature sensor is arranged in the rotating top frame, the contact type temperature sensor is connected with the cooling mode controller, a cooler fixing rotating disc is rotationally arranged above the knife rest, a water jetting type cooling nozzle and a spraying type cooling nozzle are fixedly connected to the cooler fixing rotating disc, the cooler fixing rotating disc is used for enabling the water jetting type cooling nozzle and the spraying type cooling nozzle to be switched between the working position and the auxiliary position by rotating, the cooler fixing rotating disc is connected with a rotating motor, and the rotating motor is connected with the cooling mode controller. The numerical control gear hobbing machine has the advantages of being accurate in heatingposition and good in gear processing effect in the machining process.

Description

technical field [0001] The invention relates to the technical field of gear processing equipment, in particular to a numerically controlled gear hobbing machine. Background technique [0002] Gear hobbing machine is the most widely used machine tool among gear processing machine tools. It can cut straight and helical cylindrical gears, and can also process worm gears and sprockets. A gear processing machine tool for processing straight, helical and herringbone cylindrical gears and worm gears with a hob according to the generation method. When this kind of machine tool uses a special hob, it can also process various special tooth-shaped workpieces such as splines and sprockets. Existing gear hobbing machines usually use a mandrel to fix the gear, then use a top frame to support the gear and then rotate the mandrel, and at the same time turn the hobbing cutter for processing. In this process, only the gear processing position is cooled, and the top frame rotates at a high sp...
