Description

Technical Field

[0001] The utility model relates to the technical field of spherical grinding machines, in particular to a spherical surface processing grinding machine. Background Art

[0002] Spherical grinders are suitable for grinding various spherical parts and are used in most mechanical production industries. There are many kinds of spheres that need to be ground. The clamping force during grinding will also affect the quality of grinding. If the clamping force is too small, the sphere may move, resulting in an uneven polished spherical surface.

[0003] The existing spherical grinder can refer to the utility model with patent publication number CN217255028U, which discloses a spherical grinder for processing glass rods, "including a base platform horizontally mounted on the spherical grinder and a horizontally movable drive shaft, the drive shaft is horizontally arranged just above the base platform, one end of the drive shaft is fixed to the output end of the drive device, and the other end of the drive shaft is detachably locked to the glass rod through a locking sleeve and a rod clamp." The utility model supports the rotating glass rod through a rotating support seat, which can effectively prevent the glass rod from being broken due to the lack of support in the middle due to its long length during processing. However, for the grinding of metal balls, a clamping device with a larger clamping force is required.

[0004] In order to solve the above problems, this application proposes a spherical surface processing grinder. Utility Model Content
