The surface machining device has the advantages that the machining device is simple in structure, convenient to operate and even in grinding, and surface figure precision of the surface of the lens is high; the machining process is convenient to control, the rotation linear speed of the curvature center of a spherical face and the rotation linear speed of the outer diameter of the spherical face are guaranteed to be the same through adjustment of the amplitude of the die and the deflection angle of the die, the evenness of lens grinding is improved, the die realizes the effects of the integrated linear speed for grinding the surface of the lens to be machined and overall grinding of the lens, local errors are eliminated, and the precision requirement for the high-precision hemispherical lens is met.
Description
Technical field
The utility model relates to a kind of surface processing device of packaged lens.Belong to optical instrument spare manufacture field.
Background technology
The hemisphere optical lens refers to that the part half angle is the spherical lens of 90 degree, such optical element is along with the update of development in science and technology and photoelectron instrument, be widely used in ultrashort focal length projecting apparatus, in the modern photoelectron new instrument such as ultra-large vision field video recorder and supervision instrument, it is the core key part of all kinds of new instrument.The processing of spherical optics part and production be Bian grinding from coarse to fine forms to the processed lenses of need with Standard Module, until polishing is all the process of grinding.The precision index of spherical optics part refers to surface figure accuracy and radius precision and surface roughness (fineness).And surface figure accuracy is directly connected to image quality and the resolution ratio of instrument, is the core index of device identity.Due to the hemisphere optical mirror slip in the attrition process process, mould can't significantly swing in the center of curvature of processed eyeglass, and main shaft is when driving the lens high speed rotation that needs processing, cause the rotational line speed of the center of curvature of sphere and external diameter inconsistent, therefore produce sphere external diameter edge and center of curvature grinding degree varies causes, cause machined surface surface figure accuracy and local generation error, and then have influence on the face shape of whole eyeglass and the precision of local error.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is to provide a kind of surface processing device of high accuracy packaged lens, and the lens face shape deflection precision of utilizing this processing unit (plant) to process is high, local error is little.
The technical solution adopted in the utility model is:
The surface processing device of high accuracy packaged lens, comprise swinging axle, the stylus head, the mould that is connected with the stylus head that are connected with the swinging axle bottom that is connected with the machining tool rocker head and work the fixture that supports fixation, described fixture be arranged at mould under, the arc radius of the abradant surface of described mould is slightly larger than the arc radius of to be processed of lens.
The arc radius large 0.5-1um of the arc radius of the abradant surface of described mould than to be processed of lens.
The utility model has the advantages that: processing unit (plant) is simple in structure, convenient operation, grinding evenly, the lens surface surface figure accuracy is high; Process is convenient to control, by regulating the amplitude of oscillation and the drift angle of mould, the center of curvature that guarantees sphere is consistent with the rotational line speed of external diameter, improve the uniformity of mirror grinding, reach mould to the overall wire speed of lens working surface grinding with to the effect of minute surface integral grinding, eliminate local error, meet the required precision of high accuracy hemisphere eyeglass.

Fig. 1 is the structural representation of the utility model processing unit (plant).
Fig. 2 is a certain state diagram of the utility model process.
Wherein: 1, machining tool rocker head, 2 swinging axles, 3, the stylus head, 4, mould, 5, fixture, 6, the abradant surface of mould, 7, to be processed of lens, 8, lens.
The specific embodiment
As shown in Figure 1, the surface processing device of high accuracy packaged lens, comprise the swinging axle 2 that is connected with machining tool rocker head 1, the stylus head 3 that is connected with swinging axle 2 bottoms, the mould 4 that is connected with stylus head 3 and work the fixture 5 that supports fixation, fixture 5 be arranged at mould 4 under, the arc radius large 0.5-1um of the arc radius of the abradant surface 6 of mould than to be processed 7 of lens.
Add man-hour: lens 8 are fixed on upper (as shown in Figure 2) of described fixture 5, allow lens and mould centre first contact, to eliminate the irregular error that is produced of grinding that causes because linear velocity is inconsistent; Then adjust mould and the drift angle and the amplitude of oscillation that need lens working, be about to mould pressing tuningout certain angle, the mould left and right amplitude of oscillation is not waited; For example: get drift angle 15 degree, the amplitude of oscillation 50 degree, namely left swing 10 is spent, right pendulum 40 degree; If get the amplitude of oscillation 40 degree, namely left swing 5 is spent, right pendulum 35 degree.The center of curvature that guarantees sphere is consistent with the rotational line speed of external diameter, improve the uniformity of mirror grinding, reach mould to the overall wire speed of lens working surface grinding with to the effect of minute surface integral grinding, eliminate local error, meet the required precision of high accuracy hemisphere eyeglass.
