Abstract
The utility model belongs to the technical field of precision mechanical equipment manufacturing, and provides a spherical optical lens polishing machine. The spherical optical lens polishing machine comprises a frame (11), a main shaft, a driving transmission mechanism used for driving the main shaft to swing, and a supporting weighing device used for compressing a lens needing polishing. The driving transmission mechanism comprises a motor (13), a driving wheel (15) and a pushing rod (14), and the main shaft is of an electric main shaft structure supported by air bearings. Due to the adoption of the electric main shaft structure supported by the air bearings, a steel ball conducts axial supporting on rotors of the electric main shaft in the axial direction, and the steel ball is in point contact with a rear cover, so that when the rotors rotate, the rotors are limited in the axial direction, and the rotors are prevented from shifting in the axial direction. The two air bearings are adopted to conduct radial supporting on the rotors, and due to the facts that the air bearings have higher rotation precision, and mechanical contact does not exist between the rotors and the air bearings, the rotating precision of the air bearings always keeps stable.
Description
Technical field
The utility model belongs to the manufacturing technology field of accurate mechanical equipment, is specifically related to a kind of spherical optics lens polishing machine
.
Background technology
Eyeglass is broadly divided into: level crossing, spherical mirror and aspherical mirror; Wherein spherical mirror occupies suitable proportion in optical mirror slip, and the application of spherical optics eyeglass is very extensive, as: glasses, photograph, accurate measurement etc.; Spherical optics eyeglass is a lot of for the field of accurate measurement in addition, as precision mechanical part dimensional measurement machine, and the riflescope of military industry field, the accurate measurement of aerospace field, signal transmission etc.; China has developed into the maximum sphere sphere optical mirror slip producing country in the whole world at present; In the spherical optics eyeglass that China produces, there is a large amount of spherical optics eyeglasses to export to abroad, yet, the precision of the spherical optics eyeglass of producing due to China is low, F-number is (note: the precision of the larger expression eyeglass of F-number is lower bigger than normal generally, especially behavior tolerance is larger), can not use in war industry; And the spherical optics eyeglass of external the produced superhigh precision for war industry forbids again China to be sold, and the precision that therefore improves spherical optics eyeglass is the most important thing.
The crucial production equipment of production spherical optics eyeglass can be divided into substantially: milling and grinding machine, grinder, polishing machine and coating machine; The optical mirror slip quality that China produces is generally on the low side, and its reason is mainly the backwardness of optical mirror slip process equipment, and key is wherein the backwardness of lens polishing machine quality, and the quality that improves lens polishing machine is to improve the most important thing of the processed finished products quality of optical mirror slip.
Polishing machine can be divided into pendulum polishing machine and bottom polishing machine two classes, and the manufacture of upper pendulum polishing machine is easier to, and manufacturing cost is lower, generally only have bottom polishing machine manufacturing cost 15% to 30% between, but the machining accuracy of upper pendulum polishing machine is starkly lower than bottom polishing machine; The difference of upper pendulum polishing machine and bottom polishing machine is: the main spindle's of above putting polishing machine polishing is motionless, and eyeglass swings with saddle weight; And the lens position of bottom polishing machine is motionless, the main shaft swing of shaking the head along about eyeglass radius.
Here take bottom polishing machine as example, and bottom polishing machine of the prior art includes framework, main shaft, the drive transmission device swinging in order to drive shaft and in order to compress the support weight of required polishing eyeglass; Described drive transmission device includes motor, drive and push rod; Described motor is fixed on framework, and the output shaft of motor is connected with drive by belt, on the end face of described drive, push rod is installed, and on the end face of described drive, has push rod along the sliding tray of its slip; The other end of described push rod is connected with the base that is placed with main shaft, drives described base, main shaft to vacillate now to the left, now to the right on framework under the effect of motor, and eyeglass is processed;
The structure that described main shaft adopts ball bearing to support, and main shaft is built-in with the rotation of AC driven motor drive shaft; Described support weight includes and supports adjustable plate, counterweight adjusting lever and counterweight platform; Described support adjustable plate is fixed on the top of framework; Described counterweight adjusting lever is through supporting adjustable plate, and described counterweight platform is fixed on one end of counterweight adjusting lever, and be positioned at main shaft directly over.
, there is the poor problem of main shaft running accuracy in the main axle structure that the bottom polishing machine of said structure adopts ball bearing to support, the running accuracy of main shaft comprises radial rotary precision and axial upper and lower displacement precision.
Optical mirror slip when doing polishing, main shaft and spindle rotor be radially subject to certain frictional force, so radial support power and radial rigidity that spindle rotor is accepted are extremely important, radial support power and the radial rigidity of the rotor of ball bearing main shaft are larger, within the scope of the radial load of certain strength, almost can think that its radial support power and radial rigidity are not subject to the impact of radial load size, running accuracy while not only being subject to radial load with ball bearing itself is relevant, definite says, relevant with the running accuracy of rotor; Due to Mechanical Contact between ball bearing and rotor, prolongation along with service time, wearing and tearing between ball bearing and rotor are increasing, cause the running accuracy of rotor to decline, thereby affect the machining accuracy of spherical optics lens polishing machine, in the main axle structure that ball supports in addition, also have the shortcoming that axial displacement is large.
