Description

Technical Field

[0001] The utility model relates to the technical field related to production and processing of artificial crystals, in particular to a crystal blank fixing fixture used for artificial crystals. Background Art

[0002] When measuring the crystal phase of a crystal blank in an artificial crystal, an X-ray diffractometer is usually used to draw the XRD spectrum of the crystal blank by utilizing the diffraction phenomenon of X-rays in the crystal. However, when operating the X-ray diffractometer, the crystal blank is usually placed on an operating table. The structure of existing artificial crystal blanks is relatively complex, which makes it impossible for the X-ray diffractometer to complete the measurement of the crystal blank in a placed state. This will undoubtedly reduce the measurement effect of the crystal blank and has a large defect. For this reason, we propose a crystal blank fixing fixture for artificial crystals.

[0023] Working principle: When positioning the crystal blank, the crystal blank is placed in the middle of each flexible splint 12, and the motor 19 is started. The motor 19 drives the active gear 192 to rotate through its output shaft, and through the meshing effect between the active gear 192 and the driven gear ring 191, the drive ring 17 can be driven to rotate with it. The positioning ring 11 is plugged in with the flexible splint 12 to limit the movement direction of each flexible splint 12, so that the rotating drive ring 17 can drive each flexible splint 12 to shrink inward and fit with the crystal blank through the sliding cooperation between the inclined arc-shaped slide groove 18 and the sliding shaft 16, so as to achieve the effect of positioning the crystal blank.

[0025] A plurality of cavities 13 are provided in the positioning ring 11 and are interconnected with the inner cavity thereof. An insertion rod 14 connected to each cavity 13 is fixedly installed at the outer end of each flexible splint 12. A sliding shaft 16 is fixedly installed at the lower end of the insertion rod 14.
