Abstract
The invention discloses an aligning device for a Michelson interference image spacing screw, which is composed of a compression spring, a screw, a spacing blot and a screw holder, wherein the screw holder is provided with a threaded hole; the compression spring is arranged in the threaded hole; one end of the compression spring contacts with a mirror fixing rod; the screw is screwed into the threaded hole to contact with the other end of the compression spring; and the spacing blot is vertical to the screw to be connected to the screw holder and inserted into the spacing slot of the screw. During the experiment, the screw rotates, a neutral position ring approaches to the end surface of the screw holder, the compression spring is compressed, and the mirror fixing rod is slightly bent; when the interference image appears on an observation screen and the circle center position of an interference circular ring needs to be regulated, the screw rotates to regulate the circle center position; and the spacing bolt and the spacing slot ensure that the screw can not be screwed out of the screw holder and can not be subjected to excessive compression. The aligning device discloses by the invention is reliable to space and low in cost, the structure is simplified, and managers are free from worry.
Description
Technical field
The present invention is applied to the adjusting of Michelson interference image home position.
Background technology
The existing pull bar aligning device of regulating the Michelson interference image center of circle mainly is made up of extension spring, threaded rod, anti-turn screw, thread bush and screw bolt seat; One end of extension spring is connected on the horizontal glass bar; The other end is connected on the threaded rod, and anti-turn screw is connected on the screw bolt seat, and an end inserts in the axial anti-rotation groove of threaded rod; The threaded hole that at first threaded rod is extruded screw bolt seat is screwed in the thread bush behind the certain-length, is screwed into thread bush in the threaded hole of screw bolt seat again.Because the pull bar aligning device in the existing Michelson interference image center of circle does not have limit function or limit function invalid; The experimenter is often arranged when regulating the home position of interference image,, the horizontal glass orientation is changed the back-outed threaded hole of screw bolt seat of thread bush; Interference image has been lost; To recover the initial position of pull bar aligning device on the other hand again, also will be screwed into thread bush and suitably be screwed into again in the threaded hole of screw bolt seat after the distance, operate very loaded down with trivial details with instrument elder generation extrusion threaded rod; Frequent expensive time check of the supvr of Michelson interferometer and the original state of recovering the pull bar aligning device; Simultaneously, existing pull bar aligning device structure is complicated too, and cost is too high.
Summary of the invention
In order to prevent that the experimenter from twisting thread bush, simplifying pull bar aligning device structure and reduce cost, the present invention has designed the spacing screw rod aligning device of a kind of Michelson interference image.
The spacing screw rod aligning device of Michelson interference image of the present invention only is made up of compression spring, screw rod, stop screw and screw bolt seat.Threaded hole is arranged on the screw bolt seat, and compression spring is contained in the threaded hole of screw bolt seat, an end in contact horizontal glass bar of spring; Screw rod is screwed into the other end of contact compression spring in the threaded hole, and stop screw is connected on the screw bolt seat perpendicular to screw rod and inserts in the stopper slot of screw rod, during experiment; Rotating screw bolt makes the meta ring near the screw bolt seat end face, and compression spring is by suitably compression; Horizontal glass bar trace is crooked, and when occurring interference image on the film viewing screen and need regulate the home position of interference circle, rotating screw bolt just can have been realized the adjusting of home position; Stop screw and stopper slot have guaranteed the screw rod screw bolt seat of can not back-outing, and it is excessive also can not compress.After experiment finished, rotating screw bolt made the meta ring away from screw bolt seat, lets compression spring and horizontal glass bar relaxed, and helped later experiment and regulated.
Advantage of the present invention is that regulating device is spacing reliable; The experimenter can not lose interference image because the adjusting home position is improper; The instrument management person does not check the state of screw rod aligning device with taking time again, and whole screw rod aligning device structure is simplified greatly, thereby cost has been reduced.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is the spacing screw rod aligning device of a Michelson interference image structural representation.
Fig. 2 is the structural representation of screw rod.
Among the figure, 1, screw rod, 2, threaded hole, 3, compression spring, 4, the horizontal glass bar, 5, vertically threaded hole 6, screw bolt seat, 7, stop screw, 8, the meta ring, 9, stopper slot.
Embodiment
In Fig. 1; Screw bolt seat (6) is fixed on the Michelson interferometer fuselage; Threaded hole (2) and vertical threaded hole (5) are arranged on the screw bolt seat (6), and compression spring (3) is contained in the threaded hole (2), an end in contact horizontal glass bar (4) of compression spring (3); Screw rod (1) is screwed into the other end of contact compression spring (3) in the threaded hole (2), and stop screw (7) is connected screw bolt seat (6) perpendicular to screw rod (1) and goes up and insert in the stopper slot (9) of screw rod (1).The aligning device structure of vertical direction and horizontal direction the same, just direction is different.
Claims (1)
