Description

Technical Field

[0001] The utility model relates to the technical field of quartz tubes, in particular to a quartz tube inner wall grinding device. Background Art

[0002] Quartz glass is made by melting various pure natural quartz such as crystal, quartz sand, etc. It has a very small linear expansion coefficient. Because it has high spectral transmittance, it will not be damaged by radiation. Other glasses will darken after being exposed to radiation. Therefore, it is also an ideal glass for spacecraft, wind tunnel windows and spectrophotometer optical systems.

[0003] The utility model patent with the patent announcement number CN218110396U is named as a quartz tube internal polishing device, including a fluid polishing device mounting frame, a fluid extrusion component is provided on one side of the fluid polishing device mounting frame, a material conveying component is provided on one side of the fluid extrusion component, and an extrusion collection component is provided at the bottom of the fluid polishing device mounting frame. In actual use, the polymer elastic soft abrasive first enters the extrusion shell through the soft abrasive feed pipe. At this time, under the action of the controller, the output end of the extrusion electric control hydraulic cylinder drives the extrusion piston to move, so that the extrusion piston can squeeze the polymer elastic soft abrasive into the conical discharge shell when it moves, and then squeeze it into the inner hole of the quartz tube installed in the material conveying component through the discharge hole in the conical discharge shell. At this time, the elastic soft abrasive passes through the inner hole to achieve the best polishing and deburring effect. This scheme can grind the inner holes of multiple quartz tubes, but grinding can be performed by injecting the polymer elastic soft abrasive into the quartz tube. After analysis, first of all, the extrusion injection method means that the polymer soft mold material will be pushed into the interior of the quartz tube under a certain pressure, but when the interior of multiple quartz tubes is polished, it is possible to contact the inner wall by extrusion injection. This contact will produce a certain friction, especially when the polymer soft mold material contains grinding components or particles. However, when the interior of a common quartz tube is polished, it is mainly to remove impurities or uneven parts inside the quartz tube and improve the surface smoothness. If this method is used to polish the interior of the quartz tube, the degree of polishing inside the quartz tube may be uneven, resulting in low production efficiency. Utility Model Content
