Abstract
The invention discloses a rotation stopping guide rail slide block device for a main body of a high-rotating-speed polishing head, which is applied to active high-speed polishing and processing of medium and large aperture optical elements. The rotation stopping guide rail slide block device consists of the main body, a rotating shaft supporting seat, a spherical bearing, a pin, a cover, a slide seat, a slide block, a linear guide rail and a connecting plate, wherein the rotating shaft supporting seat is fixedly arranged on the main body; and the slide seat is axially connected with the rotating shaft supporting seat through the cover and the pin, and a hinged part is connected by adopting the spherical bearing, so unevenness errors between the main body of the polishing head and the linear guide rail in the planar direction are eliminated through micro rotation of the rotating shaft supporting seat. Due to linear motion of the slide block structure, while rotational motion of the main body of the polishing head is limited, the revolution speed of a spindle and the active auto-rotation speed of a polishing shaft of the polishing head are increased and the motion stability is improved, so the maximal removing function can be obtained during the processing, and the requirement of suppressing vibration during high-speed rotation and rapid polishing of a polishing disc is satisfied.
Description
Technical field
The present invention relates to a kind of guide rail slide block device for high rotating speed rubbing head main body spline, this device is applicable to the initiatively high speed polishing processing of Large diameter optical element.
Background technology
Polishing head structure system in the existing optics small tool burnishing machine all adopts dovetail groove to adjust mechanism eccentric, that four-bar linkage structure restriction main body is rotated both at home and abroad.Four-bar linkage structure is in rubbing head is flatted turn moving process, and restriction rubbing head main body rotatablely moves, and makes the rubbing head translation, plays the spline effect of rubbing head.Because parallel four linkage component complex structures, part is many, relative motion between part is many, forward and reverse exchange campaign is frequent, easily produces vibration, has limited the high rotary speed movement of parallel four link type rubbing head, the accuracy of function is removed in the impact polishing, the polishing convergence efficiency is low, and fault rate is high, be difficult to realize the Large diameter optical element fast, the polishing requirement of efficient, high reliability.
Summary of the invention
The object of the present invention is to provide a kind of guide rail slide block device for high rotating speed rubbing head main body spline, this device can be controlled the moving motion of flatting turn of rubbing head main body effectively, make revolution, the rotational velocity of two eccentric rubbing heads all can reach 400r/min, guarantee that revolution and rotation do not produce any interference, do not produce vibration, improved the stationarity of moving in the polishing, the requirement that satisfy polishing disk High Rotation Speed, fast polishing, reduces to vibrate, realized the Large diameter optical element fast, the polishing requirement of efficient, high reliability.
The technical solution that realizes the object of the invention is:
Adopt the guide rail slide block device of spline: main body, shaft seating, spherical bearing, pin, cover, slide, slide block, line slideway, connecting plate form, shaft seating is fixed on the main body, slide axially is connected by cover and pin with shaft seating, adopt spherical bearing to connect in the hinged place, make shaft seating by small rotation, eliminate the rubbing head main body in the unevenness error of in-plane and line slideway.The rectilinear motion of this slide block structure in the rotatablely moving of restriction rubbing head main body, has improved the active self-rotating speed of main shaft rotation revolution speed and rubbing head buff spindle, has improved robust motion, can obtain maximum removal function in the processing.
The present invention compared with prior art, its remarkable advantage is:
(1) structurally, change the guide rail slide block structure into by former four linkage component structures, rotational motion is become rectilinear motion, simplified structure, significantly reduce mechanically operated parts relationship, reduced the alignment error of part, improved transmission efficiency, reduce fault rate, farthest avoided mechanical frequent rotating to cause to vibration.
(2) on function, the guide rail slide block device of spline can improve the speed of rotation in polishing process, and polishing disk can steadily act on element surface and carry out polishing, suppresses the requirement of vibration when satisfying polishing disk high speed rotary, fast polishing.
