Embodiment
Below with reference to drawings and the specific embodiments, describe the technical solution of the utility model in detail, so as clearer, understand invention essence of the present utility model intuitively.
Shown in seeing figures.1.and.2, the present embodiment provides a kind of fiber-optic vibration device 100, and it comprises body 1, is provided with fiber-optic vibration device on body 1, for making optical fiber 200 constantly bend to predetermined angle and straighten.This fiber-optic vibration device comprises motor 2, and motor 2 connects with a cam 3, and these cam 3 Yu Yi reciprocating type mobile mechanisms 4 connect, and by moving up and down of this reciprocating type mobile mechanism 4, make optical fiber 200 repeatedly become bending and linear state.
Particularly, above-mentioned reciprocating type mobile mechanism 4 is arranged in the chute 5 of offering on body 1, and said motor 2 drives these reciprocating type mobile mechanisms 4 to move up and down in chute 5 by cam 3.The reciprocating type mobile mechanism 4 of the present embodiment comprises push block 41, the slide block 42 for connecting with cam 3, for installing optical fibres 200 and drive optical fiber 200 to move up and down; And make itself and above-mentioned push block 41 keep the elastic component 43 of butt state for this slide block 42 of pushing tow, and this slide block 42 is provided with embedding slot 44, and optical fiber 200 be to be embedded in this embedding slot 44 with slide block 42 motions.Meanwhile, be provided with two for supporting the bolster core 6 of optical fiber below embedding slot 44, these two bolster cores 6 are symmetrical expression with respect to chute 5 and distribute, and make when slide block 42 moves down, and slide block 42 and two bolster cores 6 can be by optical fiber 200 bendings.
In the present embodiment, cam 3 can adopt cylindrical cam, makes the rotation of cam 3 become the rectilinear motion with the push block 41 of its butt, thereby realizes the reciprocating type mobile of push block 41, and push block 41 connects with slide block 42, thereby make slide block 42 realize reciprocating chute 5 is interior.
In order to reduce the wearing and tearing of the contact-making surface of cam 3 and push block 41, the present embodiment is provided with ball bearing 7 between push block 41 and cam 3, cam 3 connects with push block 41 by this ball bearing 7, making the relative motion between cam 3 and push block 41 is to roll, and has greatly reduced the wearing and tearing of cam 3 and push block 41.
In addition, the end of the slide block 42 of the present embodiment is made into half round post, and like this, it is constant that the bending radius of the optical fiber 200 after bending just can keep.
The bending radius of optical fiber 200 and angle of bend are all the important indicators of the fiber-optic vibration device 100 of the present embodiment, in order to regulate the angle of bend of optical fiber 200 easily, the present embodiment is also provided with a handwheel 8, on this handwheel 8, be fixed with a screw rod 81 extending in above-mentioned chute, between this screw rod 81 and slide block 42, be threaded connection, make to form lead-screw drive mechanism between screw rod 81 and slide block 42, like this, the rotation of screw rod 81 can the movement in chute 5 with movable slider 42.In the time need to regulating the angle of bend of optical fiber 200, can regulate above-mentioned handwheel 8, change the relative position of slide block 42 and screw rod 81, thereby change limes superiors position and the limit inferior position of slide block 42 in sliding process, reach the object that changes fibre-optical bending angle.
