Manual fine adjustment tilt table in crystal orientation instrument

Abstract

The invention relates to a manual fine adjustment tilt table in a crystal orientation instrument. The manual fine adjustment tilt table in the crystal orientation instrument comprises an upper plate assembling part, a lower plate assembling part and a connection mechanism, wherein the upper plate assembling part and the lower plate assembling part are supported by a support shaft; the connection mechanism is mounted between the upper plate assembling part and the lower plate assembling part; an adjustment hand wheel is arranged at the end of the upper plate assembling part and is used for driving the upper plate assembling part to rotate around the support shaft by virtue of the connection mechanism. According to the manual fine adjustment tilt table in the crystal orientation instrument, fine adjustment change of an angle of the upper plate assembling part is achieved by adjusting; the structure is simple and convenient to adjust and short in adjustment time, so that the efficiency for using the device is improved, the fine adjustment of the angle is guaranteed, and the measurement accuracy of the instrument is improved.

Description

technical field [0001] The invention relates to a fine-tuning tilting table, in particular to a manual fine-tuning tilting table in a crystal orientation instrument. Background technique [0002] The crystal orientation instrument is a special instrument for accurately orienting the direction of the crystal bar of the sapphire rough crystal lump processed into C (or A, M, R) crystal orientation. Taking the multi-angle sapphire crystal stick digging instrument as an example, it is composed of a lifting transmission mechanism, a rotating mechanism, a tilting mechanism, a goniometer, a data calculation device and a control device. Since the tilting mechanism is the key device in the sapphire ingot orienter, it directly affects the C (or A, M, R) crystal orientation of the ingot and whether the ingot measurement and measurement after movement can maintain a stable angle. Due to the need to measure the C (or A, M, R) crystal orientation, and the measurement angle of each crystal...
