Abstract
The utility model provides a friction wheel insurance adjusting screw for a fixed reflector of a Michelson interferometer. An annular groove is processed on the large cylinder external diameter of the adjusting screw for the fixed reflector of the Michelson interferometer; the friction wheel is sleeved on the large cylinder of the adjusting screw; a locking screw is arranged on the friction wheel in the radial direction; the locking screw fixes a friction rod between the friction wheel and the annular groove of the adjusting screw; the pressure of the locking screw on the friction rod is adjusted and the torque of the friction wheel on the adjusting screw can then be adjusted; the pressure of the locking screw on the friction rod can be adjusted by a professional, and the generated torque can only drive the adjusting screw to rotate normally; and once the resisting torque exceeds the set torque, the friction wheel skids.
Description
Technical field
The utility model relates to Michelson interferometer, is specifically related to the set screw of Michelson interferometer stationary mirror.
Background technology
Rely on the position in the set screw adjusting equal inclination interference image center of circle of Michelson interferometer stationary mirror, operation easier is very big, 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 enters does not have to transfer to the interference fringe center of circle film viewing screen middle part yet when the end or back-out come off phenomenon usually can occur, especially can cause the interference image complete obiteration 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 in 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, for the silk footpath 4 millimeters set screw is only arranged, the moment that cross bar produces may cause the improper damage of screw thread.
Summary of the invention
In order to overcome the damage that cross bar possibility double thread causes, the utility model 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 the position in the equal inclination interference image center of circle again.
Michelson interferometer stationary mirror friction pulley insurance set screw described in the utility model is exactly the annular groove of big column external diameter processing in 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 the utility model has the advantages that both coarse adjustment hot spot coincidence status of Michelson interferometer stationary mirror friction pulley insurance set screw, can accurately finely tune the home position of equal inclination interference image again, 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, the whole instrument structure is simplified.
Description of drawings
The utility model is described in further detail 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.
Among the 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 the set screw annular groove (2), and lock screw (3) is set up by the professional the pressure of friction lever (4).
Claims (1)
1. a Michelson interferometer stationary mirror friction pulley insures set screw, it is characterized in that the annular groove of big column external diameter processing in 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.
