Specifically, a clamp hoop 1521 is installed on the support frame 130. The welding gun 1522 is installed on the clamp hoop 1521 and is fixed by the clamp hoop 1521.

[0052] Specifically, the extending direction of the machine table 110 is set as a transverse direction. The quartz tube 200 is clamped and arranged transversely. Therefore, the transverse adjusting mechanism 140 drives the support frame 130 to move along the transverse direction.

[0083] The quartz tube 200 can be a quartz round tube, a quartz oval tube or the like. By using quartz tubes 200 of different shapes, quartz rods of different cross-sectional shapes such as quartz round rods and quartz oval rods can be made.

[0087] The size of the quartz rod can be controlled by controlling the rotation speed of the first and second clamping mechanisms 115 and 116, the vacuum degree of the quartz tube 200, the flame temperature of the welding torch 1522, the moving speed of the welding torch 1522, and selecting a quartz tube 200 with a suitable thickness.

[0088] In the present application, the first and second clamping mechanisms 115 and 116 can automatically rotate at a set rotation speed under the drive of the first and second rotation drive mechanisms 121 and 122, avoiding errors caused by manual operation. This automatic control ensures the stability and precision of the rotation of the quartz tube 200, improves the processing precision and consistency of the product, and significantly improves the production efficiency. The rotation and heating steps can be performed continuously, greatly shortening the processing time and improving the production efficiency.
