Description

Technical Field

[0001] The utility model relates to the technical field of machine tool fixture equipment, in particular to a three-jaw chuck jaw grinding device. Background Art

[0002] A chuck is a mechanical device used to clamp a workpiece on a machine tool. It is a machine tool accessory that clamps and positions the workpiece to be processed by radially moving the movable jaws evenly distributed on the chuck body. There are many types of chucks, among which the more common ones are three-jaw chucks and four-jaw chucks, which are usually installed on lathes, external cylindrical grinders and internal cylindrical grinders. They can also be used in conjunction with various indexing devices for milling machines and drilling machines.

[0003] An existing three-jaw chuck jaw grinding device (publication number: CN215942436U) has at least the following disadvantages: the device is clamped and fixed by three mutually staggered jaws. When clamping, the device is clamped manually, and the device does not have an intuitive pressure observation structure. When in use, the manual operation pressure cannot be well controlled, which easily causes a large clamping force. Among them, the staggered jaws may cause deformation of the grinding equipment when the clamping force is large, causing the grinding equipment to malfunction, resulting in a reduction in the service life of the grinding equipment, resulting in low practicality and applicability of the equipment. For this reason, the utility model proposes a new solution. Utility Model Content
