Embodiment Construction

[0044] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0045] Such as Figure 6 As shown, the mechanical method centering is to use a pair of coaxial chucks to clamp the optical parts with elastic force to realize automatic centering. When the parts are just clamped into the chucks, the optical axis of the parts does not coincide with the mechanical axis of the chucks, and the chucks There is only one point of contact between the cutting edge of the end face and the part. At the contact point P, a force F is generated due to the action of the elastic force. The part moves in the S direction until the contact point expands to a circle, the centering force is in a balanced state, the optical axis of the part coincides with the mechanical axis of the chuck, and the purpose of centering is achieved.

[0046] According to lens centering conditions:

Abstract

The invention discloses an edging device for meniscus lens centering and an edging method thereof. The edging device is cylindrical. The top end of the edging device is provided with an arc-shaped lens cementing face. A through hole is formed in the edging device and communicated with the edging device. The edging method comprises the following steps of starting lens edging, cementing and loading a plate, splicing a meniscus lens work-piece and the lens cementing face of the edging device through bonding glue, adjusting the parallelism between the bottom edge of the edging device and the end face of the work-piece after cementing, installing the edging device and the work-piece which are integrally bonded in a machine tool, calibrating the coaxiality of the edging device and a main shaft of the machine tool, carrying out edging on the work-piece through a machine tool grinding wheel, polishing the work-piece until the diameter of the outer circle and the total height reach the specified numerical range, unloading the plate, separating the edging device and the work-piece which are integrally bonded, cleaning the work-piece, and finishing the edging process of a meniscus lens.

Description

technical field [0001] The invention relates to the field of lens edging, in particular to an edging device and an edging method for centering a meniscus lens. Background technique [0002] In the prior art, the meniscus lenses often used in optical instruments are generally finely ground and polished optical lenses, and are generally uncentered optical lenses with center deviation. The center deviation is the degree of misalignment between the optical axis and the geometric axis of the optical lens. The center deviation of the optical lens destroys the coaxiality of the optical system, causing aberrations such as coma and chromatic aberration, and reducing the image quality. Therefore, the optical lens must correct the center And grind the outer circle and end face of the optical axis, so that the degree of coincidence between the optical axis and the geometric axis meets the design requirements. The centering and edging of the meniscus lens in the prior art is mainly carr...
