Abstract
A Michelson interferometer stationary mirror friction wheel safety adjusting screw is manufactured by adding a circular groove to the outer circle of a big cylinder of a Michelson interferometer stationary mirror adjusting screw, wherein a friction wheel is sleeved outside the big cylinder of the adjusting screw, a locking screw is arranged in the radial direction of the friction wheel, and a friction rod is fixed between the friction wheel and the circular groove of the adjusting screw by the locking screw. The moment of force of the friction wheel on the adjusting screw can be adjusted by adjusting pressure of the locking screw on the friction rod, wherein the pressure of the locking screw on the friction rod is adjusted by a professional, the moment of force produced can only enable the adjusting screw to rotate normally, and once resistance exceeds a given moment of force, the friction wheel slips.
Description
Technical field
The present invention relates to Michelson interferometer, be specifically related to the set screw of Michelson interferometer stationary mirror.
Background technology
The set screw of dependence Michelson interferometer stationary mirror is regulated the position in the equal inclination interference image center of circle, and operation easier is very large, accidentally just how has rotated, and causes hot spot not overlapping, and interference image has not all had.When relying on girt screw and the vertical pull bar screw fine setting Michelson equal inclination interference image center of circle; the pull bar screw threads usually can occur and enter and also do not have when the end or back-out come off to transfer to the interference fringe center of circle phenomenon at film viewing screen middle part, especially can cause interference image to disappear fully when the pull bar screw screws out to come off.Patent " Michelson interferometer stationary mirror cross bar set screw (application number: 2012105282363) " adds a cross bar on the set screw of stationary mirror, realized that set screw rotates that arc length strengthens and corresponding rotational angle is very little, can accurately grasp the fine setting amplitude of equal inclination interference image home position, but, the set screw of 4 millimeters is only arranged for string diameter, and the moment that cross bar produces may cause the improper damage of screw thread.
Summary of the invention
The damage that causes in order to overcome cross bar possibility double thread, the present invention has designed a kind of Michelson interferometer stationary mirror friction pulley insurance set screw, both can regulate hot spot and overlap the generation interference image, can accurately finely tune again the position in the equal inclination interference image center of circle.
Michelson interferometer stationary mirror friction pulley insurance set screw of the present invention is exactly annular groove of processing on the big column external diameter of Michelson interferometer stationary mirror set screw, friction pulley is enclosed within outside the big column of set screw, upwards there is a lock screw in the footpath of friction pulley, lock screw is fixed on friction lever between the annular groove of friction pulley and set screw, regulate lock screw to the pressure of friction lever, just can regulate friction pulley to the moment of set screw, lock screw is set up by the professional the pressure of friction lever, the moment that produces can only drive the set screw normal rotation, in case the moment of resistance has surpassed the moment of setting, friction pulley will skid.
But advantage of the present invention is both coarse adjustment hot spot coincidence status of Michelson interferometer stationary mirror friction pulley insurance set screw, can accurately finely tune again the home position of equal inclination interference image, also can prevent the damage of double thread.Simultaneously, because abandon the micro-tensioning system of original girt screw and vertical this equal inclination interference image home position of pull bar screw fully, whole apparatus structure is simplified.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of Michelson interferometer stationary mirror friction pulley insurance set screw.
Fig. 2 is the left view of Michelson interferometer stationary mirror friction pulley insurance set screw.
In figure, 1, friction pulley, 2, annular groove, 3, lock screw, 4, friction lever, 5, set screw.
Embodiment
In the drawings, a processing annular groove (2) on the big column external diameter of Michelson interferometer stationary mirror set screw (5), friction pulley (1) is enclosed within outside the big column of set screw (5), upwards there is a lock screw (3) in the footpath of friction pulley (1), lock screw (3) is fixed on friction lever (4) between friction pulley (1) and set screw annular groove (2), and lock screw (3) is set up by the professional the pressure of friction lever (4).
Claims (2)
1. a Michelson interferometer stationary mirror friction pulley insures set screw, it is characterized in that annular groove of processing on the big column external diameter of Michelson interferometer stationary mirror set screw, friction pulley is enclosed within outside the big column of set screw, upwards there is a lock screw in the footpath of friction pulley, and lock screw is fixed on friction lever between the annular groove of friction pulley and set screw.
2. Michelson interferometer stationary mirror friction pulley insurance set screw according to claim 1, is characterized in that regulating lock screw to the pressure of friction lever, just can regulate friction pulley to the moment of set screw,
Michelson interferometer stationary mirror friction pulley according to claim 1 insurance set screw is characterized in that lock screw set up by the professional the pressure of friction lever, and the moment that produces can only drive the set screw normal rotation.
