Locking device of positioning crystal holder for polycrystalline silicon cutting

Abstract

The invention relates to the technical field of polycrystalline silicon production, and discloses a locking device of a positioning crystal holder for polycrystalline silicon cutting. The locking device comprises a base, side spacing plates and a polycrystalline silicon ingot. A first sliding groove is formed in the top of the base, the side spacing plates are movably installed in the first sliding groove and located on the left side and the right side of the polycrystalline silicon ingot, and reset springs which extend to the outer walls of the side spacing plates and are fixed are fixedly mounted on the left side and the right side of the inner wall of the first sliding groove. According to the locking device of the positioning crystal holder for polycrystalline silicon cutting, a fixingnut is unscrewed, a positioning rod slides upwards, the positioning rod drives a pressing spring to move upwards through a spacing block, the pressing spring drives a second clamping plate to be separated from a first clamping plate through a sliding plate, the situation that the first clamping plate and the second clamping plate are clamped to cause inconvenient disassembling when the polycrystalline silicon ingot is disassembled is prevented, the effect of simple and convenient disassembling is achieved, and therefore the practicability of the locking device is improved.

Description

technical field [0001] The invention relates to the technical field of polysilicon production, in particular to a locking device for positioning crystal holders for polysilicon cutting. Background technique [0002] The sun contains inexhaustible energy for human beings, and the sun continuously sends huge energy into the universe. According to calculations, the energy emitted in just one second is equivalent to the energy consumed by burning 1.3 billion tons of standard coal. The heat released, and the solar energy reaching the earth's surface, is equivalent to about 200,000 times the total power generation capacity in the world at present, and the solar energy received by the earth every day is equivalent to 200 times the total energy consumed by the whole world in a year, compared with other energy sources In contrast, solar energy does not produce toxic and harmful gases and waste residues, so it does not pollute the environment. At the same time, sunlight can be obtaine...
