Fixing device for quartz crucible surface coating and brushing

Abstract

The invention discloses a fixing device for quartz crucible surface coating and brushing. The fixing device comprises a rack, a slide rod and a regulating rod, wherein two vertical plates are arrangedabove the rack; the two vertical plates are respectively arranged at the two sides of the rack; the slide rod is arranged in the middle of the vertical plate; two slide sleeves are arranged on the slide rod; the regulating rod is arranged above the slide rod; the regulating rod comprises a right-handed screw rod and a left-handed screw rod; a first moving sleeve is arranged on the right-handed screw rod; the first moving sleeve and the right-handed screw rod are engaged through screw threads; a second moving sleeve is arranged on the left-handed screw rod. The fixing device has the beneficialeffects that by rotating a hand wheel, the space between a first support block and a second support block is regulated, so that the first support block and the second support block are used for tightly jacking the inner wall of quartz crucibles with different calibers; the mounting and the dismounting of the quartz crucibles are simple and fast; the use is convenient; the application range is wide.

Description

technical field [0001] The invention relates to the field of quartz processing, in particular to a fixing device for brushing the surface of a quartz crucible. Background technique [0002] Quartz crucible has the advantages of high purity, strong temperature resistance, good heat preservation, stable quality, and corrosion resistance, so it is widely used in the melting of platinum, gold and other high-temperature alloys, as well as in the drawing of single crystal silicon. [0003] The applicant found that there are at least the following technical problems in the prior art: after the quartz crucible is formed, its surface needs to be sprayed to ensure the stability of its quality, and the diameter of the quartz crucible varies according to the requirements of use. Therefore, before spraying, it is necessary to use fixtures of different specifications to fix the quartz crucible, which also results in many specifications of the fixtures, high manufacturing costs, and indire...
