Description

Technical Field

[0001] The utility model relates to the technical field of gear milling machines, in particular to a gear milling machine protection and chip removal device. Background Art

[0002] A gear milling machine is a mechanical device used to manufacture gears and racks. Its working principle is to place the workpiece on a workbench and then use a cutting tool to machine the workpiece surface to form the number of teeth and tooth shape of the gear. Specifically, the gear milling machine uses the relative movement between the workbench and the tool holder to make the cutting tool contact the workpiece surface. The workbench can move horizontally and vertically so that the tool can completely cut the workpiece surface. At the same time, the tool holder can also move horizontally and vertically to control the position and depth of the cutting tool.

[0003] In actual operation, it is necessary to first select the appropriate cutting tool according to the required number of teeth and tooth shape, and assemble and adjust it. Then, place the workpiece on the workbench and position the tool to the workpiece surface. Next, by adjusting the movement of the workbench and the tool holder, the tool gradually contacts the workpiece surface to achieve cutting processing. By continuously adjusting the position and depth of the cutting tool, the required number of teeth and tooth shape are achieved.

[0004] During the gear cutting process, the gear milling machine in the prior art needs to lubricate and cool the cutting points of the gears at all times to ensure the processing accuracy and quality of the gears. However, a large amount of debris and oil will be generated during the cutting process. The debris and oil will be splashed to the surrounding environment of the gear milling machine under the rotation of the gear milling machine's cutter shaft. The debris and oil will enter the cutter shaft and gear fixture of the gear milling machine, which is inconvenient to clean and affects the service life of the gear milling machine.
