Gripping device for direction finder

Abstract

The invention relates to a gripping device for a direction finder, which is applied to fixing a crystal bar to measure the deviation of crystal orientation or the crystal orientation position of crystal bar processing crystal face with the direction finder. The gripping device has the structure that both sides of the gripping device are respectively provided with connecting plates, the two connecting plates are provided with coupled parallel holes with different height positions, two through axles pass through the parallel holes to connect with both ends of two nuts which can connect the two connecting plates to form a whole, screws arranged on the upright position of the middle of the nuts are connected with the nuts, the upper ends of the screws are connected with handles, the lower ends of the screws are connected with flanges, the lower faces of the flanges are bonded with rubber blankets, the lower parts of the two connecting plates are respectively provided with installing holes, and the gripping device can be installed on a sample platform of the direction finder for regulating the angle of the crystal bar. The invention can effectively realize the effect of gripping a crystal bar, has the advantages of accurate measurement, low raw material waste, low cost, simple use, convenience and solidity, and is applied to gripping crystal bars with different diameters.

Description

technical field [0001] The invention relates to a tooling device for an X-ray detection instrument, in particular to a clamping device used for an X-ray orientation instrument used for measuring the crystal orientation deviation or the crystal orientation position of a crystal bar processed crystal plane. Background technique [0002] All kinds of artificial lenses need to be processed into thin slices at a certain crystal orientation angle. As we all know, their hardness is high, resulting in time-consuming and labor-intensive processing, and relatively speaking, the price of raw materials is also high. Therefore, it is necessary to measure the crystal orientation deviation or the crystal orientation position of the crystal ingot to be processed before processing, so as to achieve accurate orientation and reduce waste of raw materials. At present, the processing manufacturers basically use the orientation instrument to detect. There are two conventional detection methods. O...
