Abstract
The invention discloses an optical platform positioning device of a direct-reading spectrometer. The optical platform positioning device comprises a sector plate; the optical platform positioning device of a direct-reading spectrometer is characterized in that a point constraint device is arranged at one end of the sector plate in a direction of a main optical axis for supporting, and a line constraint device is arranged at the other end of in the direction of the main optical axis for supporting; and a face constraint device is arranged on another triangular point part of the sector plate for supporting. The optical platform positioning device of a direct-reading spectrometer is simple in structure and convenient to use; some locating structures of a six-point positioning principle in the mechanical processing is adopted, to limit a deformation direction on a key point, namely a main optical axis, of the light path of the direct-reading spectrometer; in a short wave direction, as well as a direction where the post regulating work is convenient, the point, line and face positioning planes are adopted; through properties of being freely telescopic of the line and the face, stability of the point and the line, namely, the stability of the main optical axis, are determined; and the optical platform is freely telescopic, so that the stability of the main optical axis of the spectrometer is guaranteed.
Description
Technical field
The present invention relates to a kind of direct-reading spectrometer optical table locating device.
Background technology
Direct-reading spectrometer optical table (fanning strip) generally is the large plane of taking casting technique, has unavoidably the inner stress that participates in and retains, and in addition, optical table also can produce small distortion in the situation of temperature variation.If this distortion is control and guidance in addition not, the distortion of optical table is exactly unpredictable so, thus can not be simply during optical table work around or key point carry out the rigidity location and clamp.
Summary of the invention
Purpose: in order to overcome the deficiencies in the prior art, the invention provides a kind of direct-reading spectrometer optical table locating device, simple in structure, easy to use, the point-line-surface plane of orientation utilizes the retractile characteristic of line face, determines that the stable of Points And lines is the stable of primary optical axis.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
Direct-reading spectrometer optical table locating device comprises fanning strip, it is characterized in that: an end set-point restraint device supports on the primary optical axis direction of described fanning strip, and the other end axially arranges the line restraint device and supports on the primary optical axis direction; Another trigpoint place of described fanning strip arranges the face restraint device and supports.
Described some restraint device comprises ball stud and taper hole positioning seat.
Described line restraint device comprises ball stud and V-shaped groove positioning seat.
Described restraint device comprises ball stud and face positioning seat.
In case fanning strip expands and shrinks, fanning strip just can be along line and facial disfigurement, and the position of primary optical axis is constant all the time.
Beneficial effect: direct-reading spectrometer optical table locating device provided by the invention, simple in structure, easy to use, utilized some location structures of the principle of six-point fixing in the machining, on the key point-primary optical axis of the light path of direct reading spectrometry, the direction of distortion limited, in the shortwave direction, later stage is adjusted easily direction of Comparision, the point-line-surface plane of orientation utilizes the retractile characteristic of line face, determines that the stable of Points And lines is the stable of primary optical axis; Optical table can free-extension, thereby has guaranteed the stable of spectrometer primary optical axis.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2-Fig. 3 is the structural representation of mid point restraint device of the present invention;
Fig. 4 is the structural representation of center line restraint device of the present invention;
Fig. 5 is the structural representation of face restraint device among the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Be illustrated in figure 1 as a kind of direct-reading spectrometer optical table locating device, comprise fanning strip 1, an end set-point restraint device 3 supports on primary optical axis 2 directions of fanning strip, and the other end axially arranges line restraint device 4 and supports on the primary optical axis direction; Another trigpoint place of described fanning strip arranges face restraint device 5 and supports.
Such as Fig. 2-shown in Figure 3, the some restraint device comprises ball stud 6 and taper hole positioning seat 7.
As shown in Figure 4, the line restraint device comprises ball stud 6 and V-shaped groove positioning seat 8.
As shown in Figure 5, the face restraint device comprises ball stud 6 and face positioning seat 9.
In case fanning strip expands and shrinks, fanning strip just can be along line and facial disfigurement, and the position of primary optical axis is constant all the time.Optical table can free-extension, thereby has guaranteed the stable of spectrometer primary optical axis.
The above only is preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
