Description
[technical field]
The utility model relates to a kind of process equipment of eyeglass, particularly a kind of processing unit (plant) of aspheric surface eyeglass.
[background technology]
Traditional spheric glass, not only eyeglass is thicker, and sees that through lens periphery things has phenomenons such as distortion, distortion to take place, and is called aberration.Lighter and thinner for pursuing eyeglass, people use the material of high index of refraction to make eyeglass; Simultaneously, other people see through spheric glass and observe the wearer, also can obviously find the metaboly of its face mask.Because there are these problems in spheric glass, and is eliminated gradually.What replace it is a kind of aspherical lens, and the surperficial radian of this aspherical lens is non-sphere design, and this design has two, one compared with the advantage of sphere design eyeglass, reduces the distortion when looking thing; The 2nd, thinner than identical refractive index spheric glass.Aspherical lens not only makes the center thickness of eyeglass and edge thickness reduce, and makes eyeglass thinner, more eliminates marginal aberration, gives the wearer with natural eyesight.This aspherical lens broad view, edge does not have arc, and the image difference reduces to minimum, and image is very natural.Though claim that this eyeglass is an aspherical lens, after but the people put on one's glasses, eyeball always can rotate, and can not produce dizzy phenomenon when rotating for eyeball after the people is put on one's glasses, thereby need have a spherical area at the center of eyeglass, beyond this spherical area, just be called the aspheric surface zone.When eyeglass dispatches from the factory, need grind the blank eyeglass, make it become above-mentioned aspherical lens after, prepare according to the difference of picture frame type to joining the mirror center again.It is less at present to carry out the equipment of aspherical mirror machining at eyeglass.Look into Chinese patent, one patent No. is 85204693, the utility model patent that name is called " concave-convex paraboloid processing devices " discloses following content: " a kind of concave-convex paraboloid processing devices; it is made up of the slide bar and the link-type drive unit of fixed cutting tool; drive unit comprises drive unit, and the drive unit of the Y direction of X-direction of directions X, and it is characterized in that: the drive unit of (1), directions X is made up of moving runner, connecting rod, gunning stick; One end of connecting rod is connected with rotating manner with slide bar, and the other end is connected with rotating manner with moving runner, and the distance between tie point and the turning cylinder equals the length of connecting rod, and gunning stick limits slide bar and only slides at directions X; (2) drive unit of Y direction is made up of moving runner, connecting rod, slide block and slide rail; The drive unit moving runner of the moving runner of directions X drive unit and Y direction is coaxial, and its rotating ratio is 2: 1; Turning cylinder and gunning stick are fixed on can be along on the slide block of slide rail slip, and the other end is connected with rotating manner with the moving runner of Y direction drive unit, and the distance between tie point and the turning cylinder equals the length of connecting rod.”。The processing unit (plant) of this structure, surface to eyeglass adds man-hour, can make the spherical area of eyeglass all be processed into parabola, causes the eyeglass after the processing can not keep the accurate number of degrees, still can produce visual deformation to object on every side, also can make people's eyes produce tired simultaneously.In view of these problems, so just the someone has invented the process equipment of another kind of eyeglass, this process equipment also includes first pedestal, second pedestal, on first pedestal, high-speed electric expreess locomotive is installed, second pedestal is provided with X-axis, Y-axis guide rail and slide block, described slide block can move on X-axis, Y-axis guide rail, on this slide block, slowspeed machine is installed, in the rotating shaft of high-speed electric expreess locomotive, grinding tool is installed, this grinding tool has bistrique, in the rotating shaft of slowspeed machine work piece holder is installed, and described bistrique is a dome shape, as shown in Figure 1, this bistrique is the bulb shape.This process equipment is when grind spectacle lens, grinding effect for the aspheric surface zone is better, but in the process that workpiece moves, when bistrique when the spherical area, because the minute surface of sphere bistrique and this spherical area is not complementary, cause the sphere summit and the eyeglass sphere minimum point of bistrique to form a dead point, so cause distortion in the minimum point of eyeglass sphere.Grind like this when the eyeglass that comes out uses to the people and can cause a kind of " halation " phenomenon, make a lot of patients wear the situation that the back produces head fortune, this defective also is not improved up till now.
[utility model content]
Problem in view of the background technology existence, when the technical problems to be solved in the utility model provides a kind of grind spectacle lens, make spherical area on the eyeglass not be subjected to the influence of bistrique, make the spherical area that processes eyeglass not have the dead point and produce, can not produce the lens grinding device of " halation " phenomenon.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme to finish: a kind of lapping device of eyeglass, include first pedestal, second pedestal, on first pedestal, high-speed electric expreess locomotive is installed, second pedestal is provided with X-axis, Y-axis guide rail and slide block, described slide block can be in X-axis, move on the Y-axis guide rail, on this slide block, slowspeed machine is installed, the bistrique anchor clamps are installed in the rotating shaft of high-speed electric expreess locomotive, bistrique is installed on these bistrique anchor clamps, in the rotating shaft of slowspeed machine, work piece holder is installed, is it is characterized in that described bistrique is cylindric.
On the basis of technique scheme, first pedestal is provided with worm gear and worm screw, this worm gear and worm engaging transmission, described worm gear is connected with high-speed electric expreess locomotive, make the axis of high-speed electric expreess locomotive can depart from slowspeed machine axis and with the axes intersect of slowspeed machine, on the worm screw or first pedestal, dial is installed.
Further, on described first pedestal base plate is installed, high-speed electric expreess locomotive is fixed on the base plate, and this base plate is fixedlyed connected with described worm gear.
In the utility model, the bistrique that adopts is cylindric, when bistrique grinding eyeglass cylindraceous, aspheric curve by design is ground eyeglass, when being ground to the spherical area of design curve, because bistrique is cylindric, the middle part of its bistrique is a hollow area, thereby do not produce dead point in the background technology after spherical area ground, thereby kept the accuracy of the eyeglass spherical area and the aspheric surface zone optics number of degrees, can not produce " halation " phenomenon.The crossing angle that adopts worm gear, worm screw to regulate the axis and the slowspeed machine axis of high-speed electric expreess locomotive, promptly be to regulate the gradient of bistrique with respect to eyeglass, the optics number of degrees that spherical area is processed into and the optics number of degrees in aspheric surface zone are consistent, and the installation of dial, the angle of its adjusting can accurately be controlled, that is to say that the optics number of degrees of regulating after spherical area is ground are consistent with the aspheric surface zone.Base plate is installed on first pedestal is linked together with worm gear, can rotate along with worm gear, the rotation of worm gear can drive on the high-speed electric expreess locomotive turning cylinder bistrique along the axial dipole field of high-speed electric expreess locomotive, thereby reaches the purpose of adjusting bistrique gradient.
