Technical Field

[0001] The utility model belongs to the field of cutting technology, in particular to a cutting device for processing a gear ring. Background Art

[0002] A ring gear usually refers to a component in a mechanical device. It is usually an annular structure with a certain number of teeth distributed on it. The ring gear usually needs to have high wear resistance and strength in order to maintain stable performance during long-term use. It is usually made of high-strength metal materials, such as alloy steel or other special alloy materials.

[0003] The gear ring includes an inner gear ring and an outer gear ring. The gear ring needs to be cut during the processing. Most of the existing inner gear ring cutting devices use a cylinder to drive the tooth cutter on the cutter disc to perform cutting operations. For example, the existing authorized patent (Announcement No.: CN209273614U) is a quick cutting device for an inner gear ring. When used, the device can only perform cutting processing operations on inner gear rings of a single size, thereby reducing the processing range. Therefore, improvements are needed to address the above problems. Utility Model Content
