The invention discloses a
quartz tube fire repair process and a
quartz tube fire repair device, and belongs to the technical field of
quartz tube
processing, and the quartz tube fire repair process comprises the following steps: S1, clamping: putting a quartz tube subjected to fire repair into a clamp and carrying out coarse positioning; according to the quartz tube fire repair process and device, the centering precision and roundness are improved, on the premise that the quartz tube is not damaged, automatic centering and closed-
loop control between the axis of the tube body and the rotating shaft of the workpiece are achieved, the eccentricity is effectively reduced, the roundness and coaxiality of outer circle and inner
diameter machining are improved, it is guaranteed that the wall thickness is uniform, and the
machining risk is reduced; by means of flexible clamping and online torque / vibration monitoring, the secondary damage or
fracture risk of the quartz tube can be reduced, the
machining consistency and efficiency are improved, repairing can be completed in batches in a high-consistency mode through the automatic process, the single-piece
machining time is shortened, manual dependence is reduced, and the production efficiency is improved. The modularized clamp and the replaceable
grinding wheel enable the equipment to be adaptive to quartz tubes with different diameters and lengths, so that the clamp cost is reduced, and the remodeling time is shortened.
