Abstract
The invention discloses an optical adjusting frame, comprising a convex ball joint 201, a concave ball joint 202, an adjusting and fixing screw 203 and a compact ball joint 204, an optical element 205 is fixed on the convex ball joint 201, the relative position of the convex ball joint 201 and the concave ball joint 202 is adjusted to adjust the optical element 205 to be in the position required by an optical path, and the adjusting and fixing screw 203 is utilized to adjust the ball joint in a fixed optical path. In the invention, the adjusting and fixing screw 203 is utilized to adjust the ball joint in the fixed optical path, the traditional glue bonding fixed mode is substituted, and the firmness and load carrying capacity of the ball joint are improved.
Description
Technical field
The present invention relates to optics and laser field, relate in particular to a kind of optical adjusting frame.
Background technology
Precision optics, laser system development is in recent years very fast, requires more and more highlyer for the minute adjustment of optical element, applies day by day extensive.Globe joint is a kind of traditional optics regulative mode, its principle is as shown in Figure 1: because the convex curvature radius of protruding globe joint 101 and the concave curvature radius of recessed globe joint 102 equate, when adjusting completes, between latter two globe joint, add glue and fix, can guarantee that bondline thickness is consistent, reduce the susceptibility to temperature.But because globe joint adopts glue bond, so its life-span is limited, cannot be applied to adjusting comparatively large-scale, optical element that weight is larger simultaneously.
Summary of the invention
For the problems referred to above, the object of the invention is to relate to a kind of optical adjusting frame, reaches the object that improves its firmness and bearing capacity.
For achieving the above object, the technical scheme that the present invention proposes is: a kind of optical adjusting frame, comprise protruding globe joint 201, and recessed globe joint 202, regulates gib screw 203 and compresses globe joint 204.The convex curvature radius of described protruding globe joint 201 and the concave curvature radius of recessed globe joint 202 equate, to guarantee that the close contact of the two coordinates.
Further, described recessed globe joint 202 is fixed on and regulates in light path, and protruding globe joint 201 is activity adjustment part, and optical element 205 is fixed on protruding globe joint 201, by regulating the relative position of protruding globe joint 201 and recessed globe joint 202, just adjustable optical element 205 is to light path desired position.
Further, protruding globe joint 201 regulates by the uniform screw 203 in side with the relative position of recessed globe joint 202.
Described uniform screw 203 quantity are more than 3 or 3.
Accompanying drawing explanation
Fig. 1 is traditional globe joint schematic diagram;
Fig. 2 is the sectional view of optical adjusting frame of the present invention;
Fig. 3 is the vertical view of optical adjusting frame of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in cut-open view as of the present invention in accompanying drawing 2, a kind of optical adjusting frame, comprises protruding globe joint 201, and recessed globe joint 202 regulates gib screw 203 and compresses globe joint 204.The convex curvature radius of protruding globe joint 201 and the concave curvature radius of recessed globe joint 202 equate.Recessed globe joint 202 is fixed on and regulates in light path, and protruding globe joint 201 is activity adjustment part, and optical element 205 is fixed on protruding globe joint 201, and by regulating the relative position of protruding globe joint 201 and recessed globe joint 202, just adjustable optical element 205 is to light path desired position.
During concrete enforcement, as shown in vertical view as of the present invention in Fig. 3, protruding globe joint 201 regulates by the uniform screw 203 in side with the relative position of recessed globe joint 202, and uniform screw 203 quantity are 3.
As shown in cut-open view as of the present invention in Fig. 2, on recessed globe joint 202 corresponding to screw 203 installation places, be provided with a through hole 206, a low-angle △ θ of axle center inclination of through hole, there is half spherical shrinkage pool 207 on through hole 206 tops, and the radius-of-curvature of shrinkage pool 207 equates with the radius-of-curvature that compresses globe joint 204; Corresponding recessed globe joint 201 is provided with a threaded hole 208.Compressing globe joint 204 is placed between screw 203 and recessed globe joint 202.Due to a low-angle △ θ of through hole inclination, when rotary screw 203, drive protruding globe joint 201 to rotate, regulate the relative position of protruding globe joint 201 and recessed globe joint 202, reach the object of minute adjustment light path.Compress globe joint (204) and be positioned over shrinkage pool (207) above, compress globe joint 204 and guarantee that screws 203 and recessed globe joint 202 closely cooperate, and reach fixing object.
The present invention, by the globe joint in screw 203 adjustings, fixed light path, replaces the fixed form of glue bond, has improved firmness and the bearing capacity of globe joint.
Although specifically show and introduced the present invention in conjunction with preferred embodiment, but those skilled in the art should be understood that, within not departing from the spirit and scope of the present invention that appended claims limits, can make a variety of changes the present invention in the form and details.
