Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides an embodiment: a chuck for numerical control polishing of a lens comprises a circular sleeve 1 and a cup-shaped lantern ring 3, the cup-shaped lantern ring 3 is arranged inside the circular sleeve 1, the lens to be polished can be placed inside the cup-shaped lantern ring 3, a flexible elastic pad 7 is arranged on the upper wall inside the circular sleeve 1, the flexible elastic pad 7 can effectively buffer the extrusion of the polishing head on the lens, balls 2 are arranged between the circular sleeve 1 and the cup-shaped lantern ring 3, the arrangement of the balls 2 can enable the circular sleeve 1 and the cup-shaped lantern ring 3 to generate a relative rotation effect, a connecting rod 4 is arranged at the middle position of the lower wall of the circular sleeve 1, the novel type polishing chuck can be fixed on a traditional chuck through the connecting rod 4, the novel polishing chuck can be driven to rotate through the rotation of the traditional chuck so as to polish the lens, rolling grooves 6 are uniformly formed in the inner wall of the circular sleeve 1 from top to bottom along the circumferential direction of the circular sleeve 1, the, this neotype round sleeve 1 and cup-shaped lantern ring 3's stainless steel's setting makes this neotype life longer, has the material of resistant weak corrosion medium and chemical attack nature medium because of the stainless steel, and the polishing nature of stainless steel is strong, can make this neotype more pleasing to the eye.
Further, chamfer 5 has been seted up to the upper end of 1 inner wall of circular sleeve, and the setting of chamfer 5 is convenient for the operator and is got at the during operation and put the lens, and cup-shaped lantern ring 3's outside lateral wall contacts with ball 2, avoids cup-shaped lantern ring 3 to take place to rock.
