AI Technical Summary
Technical Problem
Existing single-crystal high-temperature alloy cutting equipment suffers from low production efficiency, unsuitability for mass production, and large orientation deviations in directional cutting.
Method used
A clamping device including a base, a base plate, an orientation adjuster, a chuck, and an orientation calibrator was designed. The orientation deviation angle is measured using a single crystal orientation detector, and the reference of the cutting machine is precisely adjusted by the orientation adjuster and the calibrator to achieve directional cutting.
Benefits of technology
It improves the precision and efficiency of cutting single-crystal high-temperature alloys, enriches the diversity of seed crystals, and is suitable for mass production and experimental needs.

Abstract
本发明公开一种用于定向切割单晶高温合金的夹持装置及其使用方法。所述夹持装置包括底座、基座、取向调节器、夹头和取向校准器，所述底座与基座通过取向调节器连接，所述基座的另一端固定夹头，所述夹头固定取向校准器和夹持单晶试样。所述使用方法包括测定单晶试样和取向校准器之间的偏离角、夹持装置的位向调节、单晶试样的位向调节和定向切割试样。本发明通过获得待切割单晶试样与校准单晶之间的晶体取向偏离角，使取向测量时与定向切割时所使用的基准，均为取向校准器上的基准，减少辅助基准的使用，极大提高了籽晶的切割精度，且精简了切割籽晶的步骤，提高了制备籽晶的便利程度和加工效率。
