Description

Technical Field

[0001] The utility model relates to the technical field of gear shaping machines, in particular to a numerically controlled gear shaping machine for machining transmission gears. Background Art

[0002] A gear shaping machine is a gear processing machine tool primarily used for machining the tooth surfaces of internal and external cylindrical gears, as well as worm gears. Its processing principle is to utilize a gear shaping cutter to perform an up and down reciprocating linear motion, while simultaneously coordinating the rotational motion of the workpiece, to cut the tooth profile on the workpiece by tooth-by-tooth cutting. Gear shaping machines are suitable for mass production of medium-precision gear parts, and are particularly effective when machining multi-link gears or gears with complex tooth profiles such as helical gears and herringbone gears. Compared to gear milling and hobbing, gear shaping machines offer certain advantages in machining range and flexibility, and can handle some non-standard or special tooth profile machining requirements. Its main machining parameters include the gear shaping cutter's tooth profile, diameter, number of teeth, and feed rate, all of which directly affect the machining accuracy and surface quality of the gear.

[0003] In the existing technology, some gear shaping machines can only perform gear shaping on one type of gear and can only process its exterior or interior, making its performance relatively simple. However, different machines are required for different gear processing, which makes the overall processing cost high. When the base of some gear shaping machines is moving, the iron chips cut off easily enter the moving device, thereby affecting the transmission of the base and easily causing the base to get stuck, which is very inconvenient for processing operations.
