Quartz tube fire repairing process and device Technical Field The invention belongs to the technical field of quartz tube processing, and particularly relates to a quartz tube fire repairing process and a device thereof. Background The common repairing method is that an oxyhydrogen welding gun is adopted to cut the area to be repaired and the area is filled by a quartz welding rod through fusion surfacing welding, after the repairing, a tumor-shaped, convex or welding seam residue is often formed on the outer wall of the quartz tube, and the residues lead the outer diameter and the inner diameter to deviate from the designed size and lead to rough surfaces, thereby affecting the sealing property, the thermal property and the optical property of the quartz tube and even affecting the assembly and the operation of a device. There are several problems with manual or semi-automatic grinding after traditional repair: 1. Most of the existing equipment relies on manual vision or simple mechanical limiting for centering, the eccentricity is high, the grinding result does not meet the requirements of roundness and wall thickness uniformity, and a pipe body is easy to damage; 2. The processing efficiency is low, the processing consistency is poor, and the batch and precise requirements are difficult to meet; 3. The traditional clamp has insufficient universality for quartz tubes with various diameters/lengths, particularly has processing risks for thin-wall long tubes and fragile quartz tubes, and can slide or deviate under the action of grinding force due to light clamping; 4. The adoption of a rigid clamp or strong clamping force can cause crack expansion or damage at a thin wall or a defective part, and the local thermal stress and the structure are discontinuous in a region after fire repair, so that secondary damage or excessive processing is easily caused by the traditional process, and the scrapping is caused. Based on the above, there is a need for a device that can automatically, precisely center, stably clamp, grind the inner diameter or outer circumference of a quartz tube during rotation, and adapt to quartz tubes of different diameters and lengths, so as to improve repair quality and production efficiency, and reduce the reject rate and the risk of labor.
