Abstract
The utility model relates to a molybdenum wire verticality collimator, and is an optical instrument which is mainly used on the linear cutting machine and is used for carrying out the non-contact measurement on the verticality error. The utility model is composed of an upper and a lower same object lens assemblies. The left and the right both sides of the front part of the object lens assembly are respectively provided with a reflecting mirror which forms the included angle of 45 DEG with the object lens assembly. The utility model moves for a section of distance on the direction of the X shaft, and the utility model detects the verticality error of the molybdenum wire on the directions of the X and Y two coordinate shafts. The utility model uses one set of light source system to simultaneously carry out the illumination on the two object lens assemblies. The utility model is likewise suitable for carrying out the measurement on the non-metal wire, so the utility model is enlarged to other situations.
Description
The invention belongs to the optical instrument class
It is that try square is placed on the reference plane that China carries out error of perpendicularity correction work to the molybdenum filament of wire cutting machine tool at present, on two axes of coordinates directions of X, Y molybdenum filament is carried out the measurement of the error of perpendicularity.Certain this method is very backward." shown in figure (1) "
In recent years, indivedual factories have copied external several Electrical Measuring Instrument, and their essential characteristic is that the side at instrument is equipped with upper and lower two contacts separated by a distance.When certain contact contacted with molybdenum filament, a corresponding pilot lamp was just luminous.When two pilot lamp are all luminous, illustrate that molybdenum filament is in plumbness on an axes of coordinates direction.Equally also need measure the error of perpendicularity on another axes of coordinates direction.Certainly, the line of two contacts must be processed into plumbness with reference plane, as measuring basis." shown in figure (2) "
The inventor does not find the practical optics instrument that the molybdenum filament error of perpendicularity is carried out non-cpntact measurement with optical principle so far.
The present invention has used upper and lower two identical objective lens " 7 ", " 9 " separated by a distance, thereby instrument can carry out projection to two zones of the upper and lower same distance of being separated by of molybdenum filament simultaneously, on projection screen, obtained molybdenum filament amplification real image." 5 " are molybdenum filaments among the figure, and " 8 " are the shadow screens.
Because instrument used catoptron " 6 ", it is installed in the one side in objective lens the place ahead, and with objective lens angle at 45, so molybdenum filament " is seen figure (3) " when a of position, can show the error of perpendicularity of molybdenum filament on the Y direction on the instrument projection screen; When instrument moves along directions X, when making molybdenum filament be in position b, can show the error of perpendicularity of molybdenum filament on directions X on the instrument projection screen, position a is the object distance of objective lens to the distance L of objective lens, and the distance of object lens when the molybdenum filament on the b of position is become sharp image is M+N, obviously M+N=L.
Because instrument used catoptron " 10 ", it is installed in the another side in objective lens the place ahead, with objective lens angle also at 45, so molybdenum filament on the b of position during projection, Y directional lighting light provides by condenser " 4 ", " 11 " equally.So just save an identical cover illuminator, both saved element, reduced cost, dwindled the volume of instrument again.
Because instrument has adopted catoptron " 1 " " 3 " and condenser " 4 " " 11 ",, can throw light on to objective lens " 7 " " 9 " simultaneously again so only need a lamp source " 2 ".
This instrument does not contact with measured object, thus to measured object without any damage.
The error of perpendicularity of molybdenum filament on two axes of coordinates directions of X, Y only needs instrument is moved some distances along directions X, just can be successively measured, do not lay for twice and do not need that instrument is turned 90 °, and improved the work effect.
Because by after the optical projection of objective lens, the molybdenum filament real image that on projection screen, has obtained amplifying, so the very little error of perpendicularity also can show, so the measuring accuracy of instrument is high.
During instrument work, the operator can monitor whole error calibration process on projection screen.
This instrument can carry out the measurement of the error of perpendicularity equally to nonmetal wire, so help instrument expansion is applied to other occasion.
As a kind of optical instrument, object lens and condenser are its important component parts.One group of data is provided now,, should constitute restriction certainly invention scope as an example that carries out an invention.
The object lens technical data:
Focal length: F=20mm object distance: L=13mm enlargement ratio: β=7
The condenser technical data:
Focal length: F=38mm object distance: L=38mm enlargement ratio: β=8
