Abstract
The utility model discloses a prism adjusting mechanism in a projection system. The prism adjusting mechanism is provided with a prism table on which a prism component is bonded; and the prism adjusting mechanism is characterized in that the prism table is arranged on the main body of an optical machine, and the main body of the optical machine is provided with mechanisms for adjusting the prism table respectively in horizontal X-Y direction and vertical Z direction. Compared with the prior art, the prism adjusting mechanism has compact structure, lowers the accuracy requirements of structural pieces simultaneously when ensuring the imaging quality of projection systems of prisms, improves the installing and debugging efficiencies of the prism, reduces the product cost and provides fast and effective realizing scheme for the batched production of products.
Description
Technical field
The utility model belongs to the projection display technique field, and what relate generally to is prism governor motion in a kind of optical projection system.
Background technology:
In containing the illuminator of prism, adopt gluing mode that prism directly is bonded on the illuminator main frame mostly, adopt this mode rear prism to maintain static.Prism as a kind of optical device of precision in optical system and the position between dmd chip and the projection objective very high accuracy requirement is arranged.Adopt bonding mode that fitting operation is had higher requirements, and the installation site precision is difficult for guaranteeing that can not adjust again, the qualification rate of product is low, has also influenced image quality.
The utility model content
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide prism governor motion in a kind of optical projection system, reduce the accuracy requirement of structural member when guaranteeing prism class optical projection system image quality, improve prism Installation and Debugging efficient, reduce cost of products, for the batch process of this series products provides implementation efficiently and effectively.
For achieving the above object, the technical solution adopted in the utility model is: prism governor motion in this optical projection system, has prism table, prism assemblies is bonded on the prism table, it is characterized in that: described prism table is arranged on the ray machine main body, is provided with prism table is realized horizontal X Y direction adjustment organization and vertical Z direction adjustment organization on the ray machine main body.
Described horizontal X Y direction adjustment organization has and is arranged on the turning axle that is used for the pre-determined bit prism table on the ray machine main body, and eccentric screw connects between prism table and the ray machine main body.
Described vertical Z direction adjustment organization has three set screw that are located on the ray machine main body, and the contact point of three set screw and prism table constitutes a plane.
Described turning axle is made of steel ball or pin.
Adopt the beneficial effect of technique scheme to be: prism governor motion in this optical projection system, have horizontal X Y direction adjustment organization and vertical Z direction adjustment organization, adopt this mechanism's prism can realize the adjustment of X, Y, three directions of Z, effectively compensate part sum of errors system cumulative errors, principle is simple, and is convenient to operation.Wherein horizontal X Y direction adjustment organization adopts steel ball (or pin) pre-determined bit earlier to the prism assemblies that is bonded on the prism table, eccentric screw connects prism table and ray machine main body, form revolute between prism table and steel ball when rotating eccentric screw, it is axle center ray machine main body rotation relatively on surface level with the steel ball that prism table drives prism, realizes the adjusting of X and Y both direction.Vertical Z direction adjustment organization: regulate sensitive position with three the corresponding prism Z of set screw directions that the ray machine bottom part body connects, the contact point of three screws and prism table constitutes a plane, adjust the height of three screws, prism table drives prism and rotates to an angle, realize the adjusting of Z axle, relatively the inclination angle of surface level is compensated, and is transferred to after the optimum condition with the adhesive curing set screw and tightens two trip bolts by instrument detecting.By such scheme as can be known, prism accurately is fixed on the ray machine main body by regulating compensation: the position that has guaranteed the relative optical axis of prism, eliminated the influence of part error by the position adjustment to system imaging, guaranteed prism respectively with the depth of parallelism of projection objective flange and DMD locating surface.Thereby projected picture center position and screen resolution have all obtained better controlled; Reduced simultaneously accuracy requirement to a great extent to structural member.Reduce the accuracy requirement of structural member and the qualification rate of structural member when guaranteeing prism class optical projection system image quality, for the production in enormous quantities of product and effective control of cost provide strong support.
