Description

Technical Field

[0001] This utility model relates to the technical field of gear hobbing machine equipment, specifically to an auxiliary cooling device for gear hobbing machines. Background Technology

[0002] In the current field of machining, in addition to conventional machining using machine tools, other specialized machining equipment is also used to perform other machining on parts. Gear hobbing machines perform gear hobbing on the outer surface of cylindrical workpieces, and lettering machines also perform gear hobbing on the outer surface of cylindrical workpieces. Gear hobbing machines are machine tools based on the generating method principle and are used to process gears, racks and other toothed parts. Their core function is to efficiently process high-precision tooth profiles through the meshing motion of the hob and the workpiece.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, during gear hobbing, the high-speed friction between the cutting groove and the workpiece blank generates a lot of heat. If the auxiliary cooling device is inconvenient to cool down, the heat cannot be dissipated in time, the dimensional accuracy of the workpiece blank will deviate from the design requirements, the meshing clearance between the cutting groove and the workpiece will change, and the key parameters such as the tooth profile and tooth pitch will have errors. At the same time, if it is inconvenient to limit the workpieces of different sizes, for workpieces with smaller sizes, they will shift, shake or even fly out under the action of cutting force. For workpieces with larger sizes, the workpiece cannot be adapted to the support range and may exceed the processing area of ​​the equipment, resulting in poor practicality.

[0004] To address the aforementioned problems, the inventors have proposed an auxiliary cooling device for gear hobbing machines. Utility Model Content
