The common positioning method now is to support the quartz tube products on the conical surface of a V-shaped jig, and then manually adjust the left and right positions to complete the welding and fine firing. The conical surface control of the V-shaped jig can only play a supporting role. During processing, the welding gun needs to be adjusted back and forth, which makes processing inconvenient. The V-shaped jig itself is very heavy, making it inconvenient to use and carry manually, and it is not very versatile. Summary of the invention

[0005] Quartz tube products are loaded on the mounting fixture to achieve positioning, and the rollers on the support unit are used to support the quartz tube. The rollers are rotatably installed on the bracket, and the rollers support the quartz tube so that the quartz tube can rotate. During the welding and fine firing process, the rotation of the quartz tube facilitates the fire processing of different positions of the quartz tube. A sunken avoidance groove is set between the two rollers on the bracket, so that the quartz tube will not collide with the bracket after loading, ensuring the stable support of the quartz tube. The spacing between the two rollers can be adjusted to adapt to quartz tubes of different sizes and specifications, with good versatility. During operation, the spacing between the two rollers is adjusted according to the diameter of the quartz tube to adapt to the support of the quartz tube, ensuring the stability of the quartz tube support.
