Machine head capable of freely rotating and used for processing myopic lens

Abstract

The invention discloses a machine head capable of freely rotating and used for processing a myopic lens, which comprises a cradle machine head, and the cradle machine head is of a C-shaped structure; a rotatable rotating head is arranged at the upper end of the cradle machine head; a rotating mechanism I is arranged between the rotating head and the cradle machine head, and the rotating mechanism I comprises a small turbine, a small worm and a small synchronizing wheel; a workbench is arranged on the cradle machine head; a telescopic ejector block is arranged on the workbench, and the ejector block is correspondingly arranged below the rotating head; the ejector block and the rotating head rotate synchronously; a rotatable air cylinder barrel is arranged in the cradle machine head; an axis is arranged at the bottom of the air cylinder barrel; and a guide rod I and a guide rod II are arranged in the air cylinder barrel. A piston rod drives the ejector block to move up and down and is matched with the rotating head to clamp and fix the lens, the ejector block and the rotating head rotate synchronously, and the piston rod can continuously rotate by 360 degrees clockwise and anticlockwise for a long time to freely machine a product; and various complex and simple myopic lenses can be processed.

Description

technical field [0001] The invention relates to the technical field of myopia film processing equipment, in particular to a freely rotatable machine head for processing myopia films. Background technique [0002] Myopia glasses are used to correct vision so that distant objects can be seen clearly. The principle of myopia glasses is: the myopia lens is a concave lens, the concave lens has the effect of diverging light, and the concave lens forms an upright and reduced virtual image, which makes the image distance longer and makes up for the premature collection of light on the retina due to the deformation of the lens in myopia. The front defect allows the image to fall exactly on the retina. [0003] Myopia film requires multi-angle processing such as edging and grooving. However, the existing myopia film processing equipment can only perform horizontal, vertical, and up-and-down transmission to complete the edging process after the lens is clamped, and cannot rotate in th...

AI Technical Summary

Problems solved by technology

[0003] Myopia film requires multi-angle processing such as edging and grooving. However, the existing myopia film processing equipment can only perform horizontal, vertical, and up-and-down transmission to complete the edging process after the lens is clamped, and cannot rotate in the direction of rotation. Reprocessing, bevel cutting, beveling, drilling, edge groove processing and other operations cannot be realized

The piston rod of the existing equipment cylinder cannot rotate for a long time. Rotating the piston rod will accelerate the friction between the dust-proof ring and the piston rod and the wear-resistant belt of the piston ring and the cylinder wall of the cylinder, which will affect the service life
