Abstract
The invention relates to a rail-free two-dimensional translation adjustment mechanism by utilizing an omega spring. An adjusted frame is arranged in a base seat. The mechanism is characterized in that the four planes of the adjusted frame are mutually perpendicular and orthogonal; the omega spring is arranged in and fixedly connected with the base seat, and is freely contacted with the adjusted frame; mutually perpendicular and orthogonal adjusting screws are respectively arranged in the X and the Y directions of the base seat; the two screws are contacted with the adjusted frame through round heads, and the pressure of the screws is provided by the omega spring; on the plane Z vertical to the planes X and Y, two parallel plates are fixed on the base seat, and the entire adjusted frame is clamped between the two parallel plates in a state that a removable play is reserved. The rail-free two-dimensional translation adjustment mechanism by utilizing the omega spring has the advantages that while the two-dimensional translation adjustment is completed, a two-layer rail mechanism is eliminated, therefore, the volume is greatly reduced, the overall structure is simple, and the operation is reliable.
Description
Technical field
The present invention relates to a kind of mechanic adjustment unit, be specifically related to a kind of non-extensible guide two-dimension translational controlling mechanism of the Ω of utilization type spring.
Background technology
Translational adjustment all needs guiding mechanism in general governor motion, and regulated device only moves along the direction of required adjustment when adjusting with assurance, and constant in the other direction holding position.Guiding mechanism commonly used is all kinds of guide rails.In common adjusting mechanism, just need three guide rail mechanisms, two-dimension displacements just to need two guide rail mechanisms like this as the displacement that needs to adjust space three-dimensional.Two guide rail mechanisms structure that overlaps is just huger.The space is often less in some optical instruments, is difficult to hold bigger governor motion.Therefore need the small and exquisite governor motion that can satisfy space requirement.
Summary of the invention
In order to fill up the above-mentioned blank of prior art, the non-extensible guide two-dimension translational controlling mechanism that the purpose of this invention is to provide a kind of Ω of utilization type spring, this mechanism is when finishing the two-dimension translational adjusting, reduced volume significantly, the optical instrument that can be suitable for compact conformation uses, and this class optical instrument requires governor motion to take up room less.
The scheme of finishing the foregoing invention task is: a kind of non-extensible guide two-dimension translational controlling mechanism of the Ω of utilization type spring, and be adjusted framework and be arranged in the pedestal, it is characterized in that,
Be adjusted four mutual perpendicular quadratures in plane of framework;
Be provided with Ω type spring in pedestal, this Ω type spring and pedestal are free contact condition for fixedlying connected with being adjusted framework;
X, Y direction at pedestal are respectively equipped with mutual perpendicular quadrature adjustment screw; Two screws by bulb be adjusted framework and keep in touch, its pressure is provided by described Ω type spring;
With X, vertical Z plane, Y plane, be fixed with two blocks of parallel-plates on the pedestal, wholely be adjusted framework the state of play be clipped between these two blocks of parallel-plates to leave movably.
Two adjustment of turn screw can be realized respectively the non-extensible guide two-dimension translational that is adjusted framework is regulated respectively.
Above-mentioned two dimensional surface governor motion of the present invention, owing to removed guide rail mechanism, can structure is very compact in the vertical direction of adjusting the plane, adjust demand to satisfy the less instrument in some spaces.
Mechanism principle is seen accompanying drawing:
Be adjusted the carrier that framework 1 is an optical element, adding four mutual perpendicular quadratures in plane in man-hour.At the adjustment screw 2,3 of X, Y direction also perpendicular quadrature mutually, two screws by bulb be adjusted framework and keep in touch, its pressure is provided by Ω type spring 4.Ω type spring 4 and pedestal 5 be for fixedlying connected, and is adjusted framework 1 and is free contact condition.By two parallel-plate (not shown) that are connected with pedestal the whole framework that is adjusted being clamped (leaving movably play), guarantee the reliability of mechanism kinematic with the vertical Z plane of X, Y plane.The coordinate figure of another dimension remains constantly when any one dimension is adjusted like this, and promptly the two dimension adjustment of this mechanism is separate.This mechanism utilizes two mutual vertical edges that are adjusted framework to play the guiding role, and utilizes Ω type spring to apply snap-in force.
More optimize and more particularly, in the such scheme of the present invention, the described framework that is adjusted contacts by bulb with adjusting screw, its contact condition is a contact condition.With contacting of Ω shape spring is the line contact condition.Can make by this way of contact to be adjusted framework and to sentence a kind of stable attitude constantly, guarantee the reliability of adjusting.
The non-extensible guide two-dimension translational controlling mechanism that utilizes Ω type spring of the present invention when finishing the two-dimension translational adjusting, has omitted two-layer guide rail mechanism, has reduced volume significantly, and one-piece construction is simple, reliable operation.
