Description
Technical field
The utility model relates to a kind of X-ray diffractometer and measures the special-purpose sample stage of the fiber degree of orientation.
Background technology
Polycrystalline material is made up of many crystal grain, if the crystalline orientation of these crystal grain is fully random, then the macro property of this crystal is isotropic.Yet behind the deformation processes such as general polycrystalline material process is rolling, stretching, extruding, spinning, wire drawing, some regularity can appear in the crystalline orientation of each crystal grain, and material also just presents certain anisotropy.In polycrystalline material, certain regularity appears in the crystalline orientation of crystal grain, and perhaps the crystallography face is concentrated toward some certain surface of material profile, and perhaps crystallographic direction and crystallography face all have concentrating to a certain degree, then claim to have preferred orientation in this polycrystalline material.The crystallographic direction of fibrous material tends to be parallel to the silk direction of principal axis of material, becomes rotational symmetry to distribute, and generally represents the size of material preferred orientation degree with the degree of orientation.
The utility model content
The purpose of this utility model provides a kind of X-ray diffractometer and measures the special-purpose sample stage of the fiber degree of orientation, and is simple in structure, easy to use, the degree of accuracy height.
For achieving the above object, technical scheme provided by the utility model is: a kind of X-ray diffractometer is measured the special-purpose sample stage of the fiber degree of orientation, include motor, worm screw, worm gear, base, guide rail, slide block, set screw and fixed block, described motor is connected with worm drive; Described worm and wheel is connected with a joggle; Described base and worm gear are accurately located correspondence by axis hole; Described fixed block and guide rail are fixedly installed on the base, and described slide block is located in the guide rail slidably; Described set screw one end is connected with slide block, and an end is connected with fixed block.

Embodiment:
A kind of X-ray diffractometer is as shown in Figure 1 measured the special-purpose sample stage of the fiber degree of orientation, includes stepper motor 8, worm screw 7, worm gear 6, base 5, guide rail 4, two slide blocks 3, set screw 2 and fixed blocks 1, and described stepper motor 8 is in transmission connection with worm screw 7; Described worm screw 7 is connected with a joggle with worm gear 6; Described base 5 and worm gear 6 are accurately located correspondence by axis hole; Described fixed block 1 and guide rail 4 are fixedly installed on the base 5, and described slide block 3 is located in the guide rail 4 slidably; Described set screw 2 one ends are connected with slide block 3, and an end is connected with fixed block 1.
Fiber sample is fixed on above two slide blocks 3 by screw and press strip, and rotation set screw 2 is stretching fiber sample.Set screw 2 one ends are connected with slide block 3, and an end is connected with fixed block 1, rotation set screw 2, and slide block 3 promptly moves in orbit.Press strip and above the slide block design have miniature sawtooth to make keeping parallelism between the sample.Convenient in order to change sample, fixed block 1, guide rail 4 are installed on the base 5, and base 5 can whole take off above sample stage, by one group of reed, is connected with worm gear 6, accurately locatees by axis hole between base 5 and the worm gear 6.
Stepper motor 8 is passed to worm screw 7 to rotation by one group of gear drive, worm screw 7 drives worm gear 6 and rotates, worm gear 6 drives sample and rotates, thereby make sample and diffraction plane become different angles, promptly transference silk axle becomes the crystal of different angles to respectively attend diffraction, and the transmission of high precision worm and gear can guarantee the accurate location of sample and little stepping angle and good location repeatability.
Set scanning angle, the control sample stage is rotated by predetermined manner, accepts the scanning strength signal that detector is beamed back simultaneously, draws the test collection of illustrative plates, and scanning calculates the degree of orientation of sample when finishing.
Instrument is by measuring the diffracted intensity of different angles, and software can calculate the degree of orientation of sample, and degree of orientation computing formula is: as the degree of orientation=diffraction peak high wide/180 °
The degree of orientation of measuring fibrous material is at first stretching sample, because fibrous material all is soft generally speaking, we design two can clamp the device that sample can move again simultaneously in opposite directions; Secondly, sample is wanted and can be shifted one's position, and makes with the silk axle to become the crystal of different angles to respectively attend diffraction, and we design a cover worm-and-wheel gear, drive the sample rotation, and sample is positioned over the worm gear center, satisfies the transmission scan mode.Drive sample and rotate the mode that also can select Harmonic Gears, consider that cost also has durable degree, so select worm-drive.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
