The collimator can drive the collimator core to rotate by using the rotation of the stepper motor and can realize auto-control easily, so that manual replacement of the collimator is unnecessary for X-ray fluorescence spectrometer during sample testing process, and the safety protection problems brought by the manual replacement of the collimator are avoided, therefore the collimator has wider application prospect.
Description
Technical field
The utility model relates to Xray fluorescence spectrometer, is meant a kind of collimating apparatus that is applicable to Xray fluorescence spectrometer especially.
Background technology
In Xray fluorescence spectrometer, collimating apparatus is one of parts of instrument indispensability, and it mainly acts on and is to retrain the locus of X-ray beam and the physical dimension of X-ray beam, thereby to being located and confirm in the geometric position of analyzed sample; When analyzing the different parts of different samples or sample, should select the collimating apparatus of different geometrical size.Simultaneously, collimating apparatus rational in infrastructure can also reduce disturbs the influence of spectral line to Instrument measuring precision, raising instrumental analysis result's accuracy.
Existing Xray fluorescence spectrometer collimating apparatus mostly is manual replacing collimating apparatus, or different size collimating apparatus linear array, by the transmission of driven by motor tooth bar, realizes the automatic conversion of collimating apparatus.These two kinds of conversion regimes all exist complex structure, volume is big, bearing accuracy is low problem, and even more serious is that existing collimating apparatus has limited the rational deployment of spectrometer light path, directly has influence on the measuring accuracy of spectrometer.
Summary of the invention
At the problems referred to above, fundamental purpose of the present utility model is to provide a kind of collimating apparatus, and it realizes control automatically easily, and the bearing accuracy height.
For achieving the above object, a kind of collimating apparatus provided by the utility model, comprise collimation body, collimating apparatus core and location ring flange, it is characterized in that: be connected with motor cover on the described collimation body, one stepper motor is installed on the described motor cover, and described collimating apparatus core is connected with the output shaft of described stepper motor by an axle sleeve.
In the above-mentioned the technical solution of the utility model, described collimation body radially be provided with ray channel, on described collimation body, also be provided with an axial containing hole, described collimating apparatus core be arranged in the described containing hole and the axis of described collimating apparatus core concentric with the axis of described collimation body.
In the above-mentioned the technical solution of the utility model, described collimating apparatus core is a hollow cylinder structure, is distributed with the collimating aperture in some different apertures on its radial circumference, and radially the axis of ray channel is concentric on the axis of each described collimating aperture and the described collimation body.
Adopt technique scheme, the utility model has the collimating aperture in some different apertures on the collimating apparatus core, utilizes stepper motor to change the anglec of rotation of collimating apparatus core, and the collimating aperture in different apertures is docked with ray channel, realizes the conversion of ray beam diameter.And the collimating apparatus core is a hollow cylinder structure, can be good at tackling the X ray of oblique fire, can play better shielding action.The utility model uses the stepper motor rotation to drive the collimating apparatus core and rotates, realize control automatically easily, make Xray fluorescence spectrometer need not manually to change collimating apparatus, and avoided the problem of the security protection aspect that artificial replacing collimating apparatus brought in the sample test process.And, the utility model compact conformation, volume is little, and simple in structure, practical, reliable, low cost of manufacture has bigger application prospect.

Embodiment
In order to describe structure of the present utility model, characteristics and effect in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As Fig. 1～shown in Figure 3, the utility model provides a kind of collimating apparatus that is applicable to spectrometer, and it comprises the motor cover 3 of collimation body 1, collimating apparatus core 2, rigidly-fixed power plant, the location ring flange 5 that the stepper motor 4 of rotary power is provided and carries out detecting zero point.What wherein collimate body 1 radially is provided with ray channel 11, also is provided with an axial containing hole 12 on collimation body 1.Collimating apparatus core 2 is arranged in the containing hole 12, is a hollow cylinder structure, can be good at tackling the X ray of oblique fire, plays better shielding action.The axis of collimating apparatus core 2 is concentric with the axis of collimation body 1, the collimating aperture 21 in some different apertures that on the radial circumference of collimating apparatus core 2, distributed, and the axis of collimating aperture 21 is concentric with the axis that collimates on the body 1 ray channel 11 radially.Stepper motor 4 is installed on the motor cover 3, and motor cover 3 is connected by screw retention with collimation body 1.Collimating apparatus core 2 is connected with the output shaft of stepper motor 4 by an axle sleeve 22, can be as required along its axis positioning of rotating.
During the utility model work, need according to different measurements, drive stepping motor 4 action rotations, thereby driving collimating apparatus core 2 rotates in the containing hole 12 of collimation body 1, the a certain collimating aperture 21 that is distributed on collimating apparatus core 2 radial circumferences is docked with collimation body 1 ray channel 11 radially, thereby realize the conversion of ray beam diameter.
The utility model is owing to use stepper motor 4 rotations to drive 2 rotations of collimating apparatus core, the collimating aperture in different apertures is docked with ray channel, realize the conversion of ray beam diameter, so the utility model can accurately control the angle that collimating apparatus core 2 rotates, realize accurately location.And, the utility model can come the action of control step motor by computing machine, and the not only start and stop of control step motor more accurately are easier to realize the automatic conversion of collimating apparatus, improve the bearing accuracy of collimating apparatus core 2, and then improve the measuring accuracy of spectrometer.
