Hollow shaft goniometer device

Abstract

The invention relates to a hollow shaft goniometer device, wherein a goniometer shaft system adopts a hollow structure; an internal disc joint part and an external disc joint part are respectively fixed on a shell; the hollow structure of the goniometer shaft system is formed by the internal disc joint part, the external disc joint part and the shell; an electrical cable through space is reserved in the hollow structure; a left side worm and a right side worm are respectively meshed with an inner worm gear arranged on the internal disc joint part and an outer worm gear arranged on the external disc joint part; the internal disc joint part is provided with a crystal table rotation device; the external disc joint part is provided with an X-ray CCD detector and a motor used for driving the detector; the shell is provided with an X-ray generator; an external rotating disc of the external disc joint part is sheathed outside an internal rotating disc of the internal disc joint part in a way of concentric rotation. According to the hollow shaft goniometer device, an internal fixed disc and the internal rotating disc can freely and stably make non-clearance rotation with high accuracy; the whole shaft system has large carrying capacity, and a connecting line is controlled to be arranged in a goniometer, so that an excessive line is not available on the appearance; the hollow shaft goniometer device is simple in structure, low in failure rate and hidden in data wiring layout, so that the effect of being attractive in the whole can be achieved.

Description

technical field [0001] The invention relates to a material microstructure analysis instrument, in particular to a hollow axis goniometer device used in an X-ray single crystal diffractometer. Background technique [0002] X-ray single crystal diffractometer is an essential instrument for testing, analyzing and studying the microstructure of substances. The X-ray single crystal diffractometer is mainly composed of an X-ray generating device, a goniometer, and a system data control unit. Since the goniometer is the core component of the single crystal diffractometer, the requirements for repeated positioning accuracy and absolute positioning accuracy are very high during overall operation. Usually, inner sleeves and outer sleeves are used to fix the bearings, and the way to support the main shaft is as follows: figure 1 As shown, the main shaft and the support arm are driven to move by the worm wheel C and the worm D mechanism. In order to achieve high-precision operation, h...

AI Technical Summary

Problems solved by technology

In order to achieve high-precision operation, high-precision bearings, precision-machined inner sleeve A and outer sleeve B, and various shafting parts are used; the goniometer with this structure has many parts, many processing procedures, complex processes, assembly, debugging and testing The process is cumbersome, there are too many links that are prone to mistakes, and it is easy to generate redundant costs

The layout of various data wiring on the goniometer is complicated, which is easy to cause entanglement and affects the overall appearance of the instrument
