Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
It is a kind of optical axis fixed clamping device as Figure 1-5, the left side of bottom plate 1 is provided with baffle plate 11；The inner surface of baffle plate 11 is set
There is straight pin 12；Spring 2 is arranged with straight pin 12；The outer sleeve 3 of cylinder is provided with above bottom plate；The center of outer sleeve 3
It is machined with conical first through hole 31；First through hole 31 and straight pin 12 are concentric；The diameter of section of first through hole 31 from left to right by
It is cumulative big；The right-hand member outer surface of outer sleeve 3 is machined with the first screw thread 32；Wedge 5 is placed with first through hole；The outside of wedge 5
Face is circular conical surface, coordinates with the inwall of first through hole 31 and moves, medial surface is circular arc concave surface；The right side of outer sleeve 3 is provided with sleeve 4；
The center of sleeve 4 is provided with screw-threaded counterbore 41；Screw-threaded counterbore 41 is threadedly coupled with the first screw thread 32；The end face of screw-threaded counterbore 41 is provided with circle
Cylinder 42；The center of cylinder 42 is provided with the second through hole 43 run through；The lower end of cylinder 42 is located in first through hole.
In use, by optical axis 6 pass through the second through hole 43 after, be then passed through first through hole 31, then with the end contact of spring 2,
Compression spring 2, now turn sleeve 4, under the promotion of the screw thread 32 of screw-threaded counterbore 41 and first, cylinder 42 is in first through hole
Moved forward in 31, its end face promotes wedge 5 to move inward, and because the inwall of first through hole 31 is taper, is acted in wedge 5
Constantly apply pressure to optical axis 7 under power, promote optical axis 7 to clamp；Release is direction operation sleeve 4, in the presence of spring 2,
Optical axis 7 is shot back.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The present invention's steps up
Fixture structure is simple, easy to operate, and the big I of clamping force is adjusted according to being actually needed for optical axis, does not damage optical axis table
Face, clamping stability is good, and convenient disassembly under spring effect.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all cover within the scope of the present invention.
