Abstract
The invention belongs to the precise mechanism field and relates to the precise adjusting device used in the minitype optical system or the optical component. It supplies a pitching adjusting platform, including a coping component, a chest base, a lead screw, a nut, two shaft bearings, a hand wheel, a locking nail, a locking slice, two springs, two stops, two stoppers and two scale slices. It is characterized in that it solves the problem of small adjusting range by the special design of the arc contact surface curve between the sliding block and the chest base. It can reach the adjusting quality of 30 degrees. All the accessories of the adjusting platform are processed simply so that the cost is decreased. It is proved that the pitching adjusting platform of the invention is processed simply and has high rigidity, small volume, wide adjusting range, high adjusting precision and good stability. It meets the application requirement of the adjusting range in practice.
Description
Technical field
The invention belongs to the precision optical machinery field, relate to the precision adjustment unit that is used for compact optical system or optical device.
Background technology
In the debuging of optical system, often to carry out the pitching adjustment to small-sized interferometer or compensator etc.The product range of adjustment that some producers provide is little, and the rigidity of structure is low, and is on the high side, can't satisfy in the test requirement to this product range of adjustment.
Summary of the invention
Background technology exists range of adjustment little, the rigidity of structure is low, can not satisfy in the test problems such as requirement to this product range of adjustment, in order to address the above problem, the objective of the invention is to, the pitch adjusting table that a kind of range of adjustment is big, volume is little, rigidity is high, be easy to process is provided.
The present invention mainly includes: cap assembly, block, leading screw, nut, two bearings, handwheel, two stops, two springs, two blocks, locking nail, stay, two scale plates; Wherein cap assembly comprises two side plates, two slide blocks, top cover, guide pillar, guide pillar support.Two side plates in cap assembly are separately fixed at the top cover both sides, and the circular arc of two slide blocks contacts with two arc surfaces of block respectively, and two slide blocks are fixed on the top cover inboard; Guide pillar is fixed on the guide pillar support, the guide pillar support is fixed on the top cover again.On block, nut and leading screw constitute screw pair by two bearing fixing at the leading screw two ends, and guide pillar is arranged in the groove of nut, and handwheel is fixed on the leading screw end; The bottom of two blocks is fixed on the block, and two stops are separately fixed on the top of two blocks; Stay is fixed on the left side of block, and locking nail is fixed on the side plate in cap assembly left side; Two scale plates are separately fixed on block right side and the cap assembly right side side plate; Two both ends of the spring are separately fixed on block and the top cover.
Principle of work of the present invention is as follows: rotation hand wheel, drive the leading screw rotation, and drive nut makes nut along the leading screw axially-movable, and nut is stirred guide pillar, makes the cap assembly motion; Slide block in the cap assembly contacts with the block arc surface, and the movement locus of cap assembly is a circular arc, thereby has realized pitch regulation.
The invention has the advantages that by arc contact surface curve and carry out specific design, solved the little problem of range of adjustment, can reach 30 ° adjustment amount slide block and block; All processing parts difficulty of processing of adjustment platform of the present invention are low simultaneously, are easy to reduce cost.Through repeatedly using proof, pitch adjusting table of the present invention is easy to processing, rigidity height, volume is little, range of adjustment is big, the degree of regulation height, and good stability can satisfy in testing the request for utilization to the product range of adjustment.
