Problems solved by technology

However, with the continuous increase of crystal size, the crystal diameter becomes larger, and the distance between the crystal growth and the crucible wall becomes smaller and smaller, so it becomes more difficult to take the crystal. Collision between crucibles, resulting in dark cracks

Embodiment Construction

[0016] The present invention is described in detail below in conjunction with accompanying drawing:

[0017] combine figure 1 , The overall structure of this embodiment is composed of a suspension ring 1, two "half-door-shaped" clamping arm structures 2, a bidirectional thread structure for opening or tightening the clamping arms, and a clamping chuck structure 3 for clamping. The lifting ring structure is fixed at the joint of the two "half-gate" clamping arm structures through lifting ring bolts 4; the upper parts of the two "half gate-shaped" clamping arm structures are connected by lifting ring bolts to ensure that the angle between the two clamping arms can be freely Adjustment, the lower part is welded on the chuck used for clamping; the two-way thread structure is composed of two bolts 5 and a cylindrical nut 6, the bolts are respectively connected at the corners of the jig arm, and the cylindrical nuts are screwed on the bolts in the same direction On the top, a recta...

Abstract

The invention provides a tool fixture for large-size sapphire single crystal. The structure is entirely composed of a hanging ring, two semi-door-shaped clamping arms, a bidirectional thread structureused for expanding or tightening the clamping arms, and a clamping head for clamping. The tool fixture is characterized in that the hanging ring is fixed at the connecting position of the two clamping arms through a bolt; the upper parts of the two semi-door-shaped clamping arms are connected through an eyebolt, so as to ensure that the included angle between the two clamping arms can be randomlyadjusted, and the lower parts of the two semi-door-shaped clamping arms are welded onto the clamping head for clamping; the bidirectional thread structure is composed of two bolts and a nut. The toolfixture provided by the invention is simple in structure, good in fastening effect, and is beneficial to the taking out of the large-size sapphire single crystal from a crucible.

Description

technical field [0001] The invention relates to a crystal fixture structure for hoisting sapphire single crystal, in particular to a tooling fixture structure for large-size sapphire single crystal. Background technique [0002] Sapphire, also known as alumina single crystal, has a hexagonal lattice structure, and its hardness is very high, second only to diamond. Because of its good light transmission, thermal conductivity and electrical insulation, as well as good wear resistance and wind erosion resistance, it is widely used in military fields, civilian fields and LED substrate materials. [0003] As the application range of sapphire materials becomes wider and wider, various sapphire manufacturers have carried out research work on large-size sapphire single crystals, and optimized them on the basis of traditional crystal sizes to achieve the purpose of improving the utilization rate of crystal materials and reducing costs and increasing efficiency. . However, as the cr...
