The invention relates to the technical field of lens
machining, in particular to a manual double-
grinding-wheel
numerical control core taking
machine which comprises a base iron
casting, a
machine head iron
casting, a manual moving lens shaft gear
assembly mechanism, a
machining chamber waterproof cover mechanism unit, a left lens shaft mechanism, a
right lens shaft mechanism and a
servo motor hollow mechanism. A left lens shaft and a
right lens shaft are directly driven by a
servo hollow motor, so that a camera and a camera
light source can directly center the lenses manually. The
machine adopts a double-
grinding-wheel mechanism, any one
grinding wheel can be selected for
machining, the double grinding wheels can also be adopted for rough grinding and accurate grinding, and the
grinding wheel mechanism adopts a guide rail and sliding block independent mechanism, is stable in precision and can be finely adjusted. The right side lens shaft adopts the design concept of a guide rail sliding block, the grinding precision efficiency is improved through the design concept, the precision is greatly improved, the coaxiality can be finely adjusted, and abrasion is not prone to occurring. Moreover, a
servo hollow motor, a lens main shaft and a servo motor are directly connected, a camera of an optical centering or
laser centering instrument can directly irradiate the center of the lens to confirm whether core shift exists or not, and then manual adjustment and confirmation are carried out.
