The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated.
Fig. 1 has shown the structure of miniature non-spherical element grinding of the present invention and burnishing device, comprises support frame (10) and is arranged at the cantilever (1) on the support frame (10).Clamp head moving up and down (6) is set on the cantilever (1), and clamp head (6) is used for clamping non-spherical element to be processed, and clamp head (6) is connected with anchor clamps rotating shaft (2), in driving lower clamp rotating shaft (2) rotation of clamp motor (3), thereby drives clamp head (6) rotation.Anchor clamps rotating shaft (2) is arranged in the lifting tube (4), and the engagement of tooth bar and adjusting gear (5) is set outside the lifting tube (4), and adjusting gear (5) rotates and can make clamp head (6) move up and down in vertical direction.Regulate the rotating shaft (11) that in the support frame (10) main motor (13) is set and transmits main motor (13) power.Two cam combinations (12) (action of cam is played in cam combination in the present invention in fact, and concrete structure and effect detail in the back) are set in the rotating shaft (11), have certain spacing distance between two cam combinations (12).The bracing frame that cooperates with each cam combination (12) supports millrind (18), the mill (21) that mill motor (20) is set on the millrind (18) and is driven by mill motor (20).
The course of work to miniature non-spherical element grinding of the present invention shown in Figure 1 and burnishing device briefly explains.Clamp head (6) will be processed the optical element blank of polishing and fixed; Clamp head (6) moves to suitable position (guarantee mill (21) can grind or the position of polishing of optical spare blank) in vertical direction; Main motor (13) thus rotate driving cam combination (12) rotates; And then promptly begin to grind or polishing process after making millrind (18) swing, millrind (18) swing to appropriate location (guaranteeing that mill (21) can the tangential grinds or the position of polishing of optical spare blank), if grind or polishing be rotation non-spherical element with a symmetry axis; Then start clamp motor (3), make clamp head (6) rotate; If grinding or polishing is the non-face of cylinder element with a symmetrical plane, then do not start clamp motor (3), clamp head (6) is not rotated.Change mill (21) and abrasive material, can implement operations such as corase grind, fine grinding, correct grinding and polishing.
Below in conjunction with accompanying drawing critical component in miniature non-spherical element grinding of the present invention and the burnishing device is described.
The less use of situation that cam combination (12) directly contacts with millrind (18), generally speaking, cam combination (12) all is through bracing frame millrind (18) to be supported.Visible from Fig. 1, bracing frame comprises push rod (14), width adjusting bar (17) and the millrind pole (8) that is linked in sequence.Push rod (14) contacts with cam combination (12), and push rod (14) is along with the rotation of cam combination (12) moves up and down.The spring (15) that also is provided with spring socket sleeve (16) on the push rod (14) and cooperates with it; The elastic force of spring (15) makes push rod (14) closely to contact with cam combination (12) all the time; To guarantee that push rod (14) is all the time along with the profile of cam combination (12) moves; Avoid because factors such as inertia cause the motion of push rod (14) and the formed theory movement of profile of cam combination (12) to produce deviation, thereby cause millrind (18) motion that deviation takes place.
The effect of width adjusting bar (17) is the distance of regulating between millrind pole (8) and the push rod (14), can clearly see width adjusting bar (17) structure in conjunction with Fig. 2 and Fig. 3.Width adjusting bar (17) one ends are to have the screw rod of regulating screw thread, and this screw rod cooperates so that width adjusting bar (17) moves on the horizontal direction of Fig. 1 with the nut that push rod (14) is gone up setting.The other end of width adjusting bar (17) is provided with adjusting nut (9), and adjusting nut (9) cooperates with lifting screw (82) on the millrind pole (8), so that lifting screw (82) (being millrind pole (8)) moves in the vertical direction of Fig. 1.See from angle shown in Figure 3; One end of width adjusting bar (17) (being provided with an end of adjusting nut (9)) has the shape of similar the shank of the key; Except that the middle lifting screw (82) that passes, also have two guide posts that pass (81), the effect of guide post (81) is to make the motion of millrind (18) more stable.
Fig. 4 has shown the structure of millrind pole (8) from another angle, and the confined state of millrind pole (8) and millrind (18).The below of millrind pole (8) is parallel two guide posts (81) and lifting screw (82), and the top of millrind pole (8) is a U type structure, and both sides are provided with alignment pin (7) in the U type mouth, slides in the chute (19) of two alignment pins (7) on millrind (18).Can find out that the distance that width adjusting bar (17) is regulated between millrind pole (8) and the push rod (14) is to realize through promoting to slide in the chute (19) of millrind pole (8) on millrind (18).
Can obtain the structure of millrind (18) in conjunction with Fig. 1 and Fig. 5; The motor shaft of millrind (18) central hole is connected the mill (21) of millrind (18) top and the mill motor (20) of below, and mill motor (20) drives mill (21) rotation stably in circular groove.In the chute (19) of four " recessed " fonts of millrind (18) two sides, alignment pin (7) can slide in chute (19).
Explain that in conjunction with Fig. 6 and Fig. 7 cam of the present invention makes up the structure of (12), cam combination (12) is combined by the single cam of two coaxial rotations, and is as shown in Figure 7.A cam combination (12) is supported millrind through a bracing frame, two cam combinations (12) about promptly having among Fig. 1, and a push rod (14) is supported in each cam combination (12).The profile of cam combination (12) or said single cam is confirmed according to the surface configuration of the non-spherical element that will process; Because requiring mill (21) that non-spherical element is carried out the tangential during processing non-spherical element grinds; Therefore under the situation of known non-spherical element finished surface equation, the movement locus of millrind (18) can be derived, thereby the curvilinear equation of the profile of cam combination (12) or said single cam can be confirmed.Visible from Fig. 6, the phase difference of two said single cams is θ, can on dividing head, accurately regulate.Regulate the contour curve that two said single cam phase difference θ can adjust cam combination (12) on the whole, can obtain the aspherical optical element (different) that profile is similar, have different parameters through a pair of said single cam combination like this like focal length.In addition, from cam contour design and processing, the cost of cam combination is lower.
Width adjusting bar (17) can be regulated the distance between millrind pole (8) and the push rod (14) among the present invention; Millrind pole (8) can be moved in vertical direction; Given millrind (18) adjusting range very flexibly, this adjustment can also compensate when wear error appears in device of the present invention except tackling the non-spherical element of multiple parameter; Like occurring wear behind cam combination (12) the work certain hour, can compensate through this adjustment.
