Abstract

This invention discloses an X-ray directional clamp and a directional method for processing the crystal reference surface. The X-ray directional clamp for processing the crystal reference surface comprises a controllable tilt table, a clamp bottom plate and a clamp top plate. The controllable tilt table is provided with a supporting surface, and the tilt angle of the supporting surface relative to the horizontal plane is adjustable. The clamp bottom plate is fixed on the supporting surface. The clamp top plate and the clamp bottom plate are arranged up and down; the clamp top plate and the clamp bottom plate are detachably fixed; a crystal fixing groove is formed between the clamp top plate and the clamp bottom plate; an opening communicating with the crystal fixing groove is formed in the clamp top plate; and the size of the opening meets the following condition that after a crystal is fixed, the crystal reference surface is located on the upper portion of the clamp top plate. The accuracy of the reference surface after processing corresponding to the crystal surfaces in the other two directions is controlled within 2' can be realized.

Description

technical field [0001] This application relates to a supporting fixture for an X-ray orientation instrument, in particular to an X-ray orientation fixture and an orientation method for processing a short-length crystal reference surface, and is especially suitable for processing the reference surface of a crystal with a length of 1-20mm . Background technique [0002] X-ray orientation instrument is a necessary supporting equipment in the field of crystal processing. According to Bragg's law, X-rays are used to irradiate the crystal. When the crystal is at different angles to the incident X-rays, those crystal planes satisfying Bragg diffraction will be detected. After testing the corresponding crystal plane of the required crystal, the crystal is clamped by the fixture, and then the required crystal plane is processed on the surface grinder. [0003] The current reference surface fixture has the following problems: Since the length of the general crystal on the market is ...
