Problems solved by technology

Therefore, whenever grinding lenses with different arc radii, jigs of different heights must be replaced to increase production costs, and if the precision of the jig height is insufficient, its adjustment becomes difficult
[0004] In addition, after the grinding plate grinds the lens, the grinding surface will form a certain degree of wear, which will cause the center of the grinding ball to shift with the degree of wear of the grinding plate, resulting in deviations in the precision of the ground lens.
However, the commonly used lens grinding machine cannot directly adjust the distance between the center of the sphere, so that it is difficult to correct the distance between the center of the sphere and the lens when the grinding plate wears, and it is often necessary to repair the grinding plate. Therefore, how to solve the above problems is the focus of the present invention. where the

Abstract

The invention provides an eyeglass grinding device which can be adjusted according to the spherical center and the diameter of the arc of the eyeglass. The invention is provided with a vertical basic plate which is connected with a grinding mechanism which can be adjusted in an inclined angle by the vertical basic plate and can be driven to swing by a driving mechanism, and a displacement mechanism which is provided with a sliding block which can longitudinally move and can be used for supporting the vertical basic plate; by adopting the structure, the grinding device can correct the amplitude of swing and the central point of the swing amplitude according to the spherical center and the diameter of the arc of the processed eyeglass correspondingly before the grinding operation is carried out, so as to position the best grinding position.

Description

technical field [0001] The invention relates to a lens grinding device that can be adjusted according to the center of the lens and the arc radius of the lens, especially a lens grinding device that can simultaneously adjust the vertical displacement, inclination and elevation angle of the grinding mechanism, so as to correct the lens according to the center of the lens and the arc radius of the processed lens. The swing amplitude and swing center point of the grinding mechanism. Background technique [0002] As shown in Figure 7, it is a commonly used lens grinding device, which has a working platform 90, on which a rotating shaft 91 is installed in a corresponding bearing seat 92 and a positioning frame 93, and the connecting rod 94 is pivoted on the The front end of the rotating shaft 91, and the connecting rod 94 has a thimble 941, and the two ends of the pneumatic cylinder 95 are respectively pivoted on the connecting rod 94 and the rotating shaft 91, and the other end ...
