Arbitrary-angle goniometer in crystal orientating instrument

Abstract

The invention relates to an arbitrary-angle goniometer in a crystal orientating instrument. The arbitrary-angle goniometer comprises a left support arm component, a right support arm component and an electric linkage mechanism, three points in the left support arm component and the right support arm component are in sliding connection with the electric linkage mechanism, one of the three points is in sliding connection with two sliding rails of the electric linkage mechanism and is connected with transmission devices in the sliding rails, the other two points are arranged on another sliding rail, and the transmission devices are driven by a driving device in the electric linkage mechanism to drive arbitrary-angle equivalent change of a prober and an X-ray generator through the left support arm component and the right support arm component respectively. The arbitrary-angle goniometer in the crystal orientating instrument has the advantages that since the distance between two shaft holes in a left support arm and a right support arm is guaranteed, equivalent angle change of a left support arm bottom plate and a right support arm bottom plate is guaranteed, further, arbitrary-angle change of the prober and the X-ray generator on the left support arm and the right support arm respectively is achieved, assembly debugging is convenient, cost is reduced while efficiency is improved, convenience and quickness in operation are achieved, and unnecessary harm to bodies is reduced.

Description

Technical field [0001] The invention relates to a goniometer device, in particular to an arbitrary angle goniometer in a crystal orientation meter. Background technique [0002] The crystal orientation instrument is a special instrument for accurately orienting the crystal rod direction of the sapphire blank crystal tuft into C (or A, M, R) crystal orientation. Taking the multi-angle sapphire crystal tuft rod orientation instrument as an example, it is composed of a lifting transmission mechanism, a rotation mechanism, a tilt mechanism, a goniometer, a data calculation device and a control device. Since the goniometer is the core device of the sapphire crystal tube orientation instrument, it directly affects the C (or A, M, R) crystal orientation and deviation angle of the crystal rod. Because the crystal orientation of C (or A, M, R) needs to be measured, and the measurement angle of each crystal orientation is different, at this stage, the goniometer can change the position of...

Problems solved by technology

Since the manual knob is driven by the threaded rod, the adjustment angle is closely related to the pitch, so higher precision requires the smaller the pitch of the threaded rod, which brings complex processing technology, and requires high-precision semi-circular arc guide rails, increasing equipment Cost; the goniometer that changes the position by changing the mounting hole also has many holes, is difficult to align, and has complex processing procedures, and the steps of adjusting the required angle of each crystal orientation in two ways are repetitive and time-consuming. The safety and health of debugging personnel are unfavorable
