Abstract
The utility model relates to a device for replacing a collimator and a filter plate of an X-fluorescence spectrometer. A guide rail connecting rack is arranged on a straight-line guide rail, a hole site-changeable collimator is mounted on the guide rail connecting rack, and a secondary filter plate is mounted on the hole site-changeable collimator; and a motor guide nut is connected with one end of the hole site-changeable collimator and is matched with a motor lead screw, and the motor lead screw is connected on a stepping motor. The stepping motor is connected with a singlechip, and the singlechip is connected with a computer. The device provided by the utility model is used for replacing collimators of different lengths or different diameters and filter plates of different materials, different thicknesses or different densities in a mechanical manner inside an energy dispersion X-fluorescence spectrometer.
Description
Technical field
The utility model belongs to, particularly a kind of switch collimators of X fluorescence spectrophotometer and filter plate device.
Background technology
The purpose of using collimating apparatus and optical filter is that elimination or the characteristic X-ray that reduces elementary X-ray spectrum, the especially target launched from X ray are composed the interference to element to be measured, can improve peak back of the body ratio, the sensitivity that raising is analyzed.Tradition uses the method for collimating apparatus and optical filter to be: 1. use fixing collimating apparatus and optical filter, itself can not change the collimating apparatus and the optical filter of other types.2. manually change collimating apparatus and optical filter, need artificial selection collimating apparatus and optical filter and installation at every turn.Native system can thoroughly be separated and can't change or change the big problem of difficulty.
The utility model content
Technical problem to be solved in the utility model is: switch collimators and filter plate device that a kind of X fluorescence spectrophotometer is provided.Use this device to be used for to change easily mechanically the filter plate of the collimating apparatus of different length, different-diameter and unlike material, different-thickness, different densities in energy dispersion X fluorescence spectrophotometer.
The technical solution of the utility model is:
A kind of switch collimators of X fluorescence spectrophotometer and filter plate device is characterized in that: the guide rail link is set on line slideway, position, interchangeable hole collimating apparatus is installed on the guide rail link, the secondary filtering sheet is installed on the collimating apparatus of position, interchangeable hole; Be connected with motor at position, interchangeable hole collimating apparatus one end and lead mother, motor is led mother and is cooperated with the motor leading screw, and the motor leading screw is connected on the stepper motor.
Described stepper motor is installed on the electric machine support, and described line slideway is installed on the electric machine support extension.
The two ends line slideway is installed on the same straight line on the described electric machine support extension, a guide rail link is set respectively on this two ends line slideway, these two guide rail links are connected to the two ends of position, interchangeable hole collimating apparatus.
Described stepper motor connects single-chip microcomputer, and single-chip microcomputer connects computing machine.
The utility model effect is: this device is used for changing mechanically in energy dispersion X fluorescence spectrophotometer the filter plate of the collimating apparatus of different length, different-diameter and unlike material, different-thickness, different densities.
