Abstract

The present invention provides a kind of spherical lens grinding apparatus improved from a kind of common lens grinding apparatus. The solving method provides the spherical tool tray with the function which can compress the under-processing lens in the direction of the axis through the center of the spherical tool tray and the capacity which can move in the direction parallel with the above-mentioned axis. The spherical oscillating body which can oscillate freely supports the above-mentioned tool tray with free rotation and has the same center with the tool tray. The above-mentioned oscillating body is supported by the spherical air bearings which has the same center with the above-mentioned tool tray. The lens grinding apparatus also provides the stop-rotation component in the axis parallel with the surface which the above-mentioned oscillating body and tool tray rotate on and through the sphere center of the above-mentioned tool tray. The center-adjusting mechanism for oscillating angle adopts the arched cam to set the center of oscillating angle.

Description

technical field

[0001] The invention relates to a lens grinding device, in particular to a lens spherical grinding device used in a processing method of an optical spherical lens. Background technique

[0002] A conventional lens grinding device includes, for example, a lens grinding machine disclosed in Japanese Patent Publication No. Sho 43-13439. This lens grinding device is provided with a freely adjustable lower plate support shaft on a swinging frame supported by a horizontal axis, which is perpendicular to the horizontal axis, and is connected by a sliding piece or its stop screw to the swinging arm through a sliding connection. To adjust the angular amplitude and center position of the swinging frame with the axis center of the above-mentioned horizontal axis as the center, the above-mentioned sliding member or its stop screw is engaged with the adjusting screw provided on the crank plate by screw fittings, and the crank plate Connected with the swing drive source, ...
