Overturning clamp for large cover of crystal growing furnace

Abstract

A related overturning clamp for a large cover of a crystal growing furnace comprises two symmetrically-arranged bracing frames, and fixed ox-horn-shaped members arranged on the bracing frame in a rotation way; each fixed ox-horn-shaped member comprises a rotation shaft, a movable clamping sheet and a bearing block; one end of the rotation shaft is connected with the corresponding bracing frame in a rotation way, and the other end of the rotation shaft is connected with the bearing block; the bearing block and the movable clamping sheet form a fixing area; the large cover is clamped in the fixing area; and two rotation bearings are coaxially arranged. The overturning clamp is capable of effectively controlling the overturning process of the large cover of the jewel furnace, is simple and convenient to operate, helps to effectively solve the problem that the large cover of the sapphire crystal growing furnace is difficult to overturn, helps to effectively improve hoisting, adjusting, cleaning and afresh assembling processes of a thermal field, and helps to greatly shorten the sapphire crystal growth period, improve production power and reduce sapphire crystal growth cost, thereby improving working efficiency, simplifying working process and reducing working risk.

Description

technical field [0001] The invention relates to a jig, in particular to a flipping jig for a large cover of a crystal growth furnace. Background technique [0002] With the development of artificial crystal science and technology, especially the development of sapphire grown by the top seed crystal temperature gradient method, the development of large-sized sapphire crystals is an inevitable trend, and the assembly requirements for sapphire crystal growth furnaces are also getting higher and higher. The temperature field assembly and temperature field adjustment of the sapphire crystal growth furnace need to lift, assemble, clean and adjust the large cover of the crystal growth furnace. Similar operations need to flip and adjust the large cover of the crystal growth furnace. The operation mode combined with manual turning is not only inefficient but also has a high safety risk and may easily lead to personal injury accidents.

AI Technical Summary

Problems solved by technology

The temperature field assembly and temperature field adjustment of the sapphire crystal growth furnace require hoisting, assembly, cleaning and adjustment of the large cover of the crystal growth furnace. Similar operations require flipping and adjustment of the large cover of the crystal growth furnace. The operation method combined with manual turning is not only inefficient but also has a high safety risk and may easily lead to personal injury accidents

[0003] Large-size and high-quality sapphire crystals have a long growth cycle and the equipment is kept at high temperature for a long time. The hoisting, assembly and adjustment of equipment are extremely important for the operation of the large cover of the sapphire furnace. The cost of crystal growth is also extremely important; the original hoisting and flipping methods are difficult to operate, low in efficiency, high in safety risks and prone to personal injury incidents
