The upper end of the guide rod 7 passes through the lifting plate 6, and the lifting plate 6 is formed into a roughly square plate-shaped structure. Two guide rods 7 are arranged, and the two guide rods 7 are symmetrically arranged on the top surface of the firing slide 5 on both sides of the lifting plate 6. The design purpose of the guide rod 7 is to limit and guide the lifting and lowering of the lifting plate 6. The top end is provided with an external thread, on which a nut 8 for limiting the upward trajectory of the lifting plate 6 is threaded, and a handwheel rod 9 is rotatably installed on the top surface of the firing slide 5. The handwheel rod 9 is formed as a roughly externally threaded rod, and a handwheel 10 for rotating the handwheel rod 9 is fixedly provided on the outer peripheral surface of the upper end of the handwheel rod 9. The lower end of the handwheel rod 9 is rotatably connected to the top surface of the firing slide 5 through a rotary bearing, and the upper end passes through the lifting plate 6 and is threadedly connected to the lifting plate 6. A flame spray gun 16 is embedded on the lifting plate 6, and the nozzle of the flame spray gun 16 is inclined upward, and the angle between the nozzle and the horizontal plane is 60°~75°, and the quartz glass lamp tube 3 on the three-jaw chuck 2 of the lathe 1 is fired by the flame spray gun 16;

[0028] The end surface of the quartz glass lamp tube 3 is fired by the firing assembly, and the height of the flame spray gun 16 can be adjusted by the lifting plate 6 to adapt to quartz glass lamp tubes 3 of different diameters;

[0029] The reinforcement assembly includes a reinforcement slide 11, which is formed into a roughly square plate-shaped structure, and its bottom surface is slidably mounted on the top surface of the guide rail 4. A support rod is fixedly arranged on the top surface of the reinforcement slide 11, and the support rod includes a support vertical rod 12 and a support cross rod 13, and the support vertical rod 12 and the support cross rod 13 are both formed into roughly cylindrical rod-shaped structures; the bottom end of the support vertical rod 12 is vertically fixed on the top surface of the reinforcement slide 11, and the top end of the support vertical rod 12 is vertically fixed on the rear end of the support cross rod 13; the support cross rod 13 is horizontally arranged, and one end thereof is connected to the support vertical rod 12, and the other end is fixedly connected to the center of the abutment plate 14;

[0030] An abutment plate 14 is installed on the support rod, and the center of the abutment plate 14 is opposite to the center of the three-jaw chuck 2 of the lathe 1. The abutment plate 14 is formed into a roughly disc-shaped structure. One side of the abutment plate 14 is fixedly connected to the support cross bar 13, and the other side is used to abut the fired end of the quartz glass lamp tube 3 on the three-jaw chuck 2.

[0031] The reinforcement assembly can make the abutment plate 14 contact the end of the quartz glass lamp tube 3 after the quartz glass lamp tube 3 is fired, so that the burnt end of the quartz glass lamp tube 3 is more secure and the existence of gaps or pores at the burnt end is avoided.

[0032] The operating principle of the quartz glass lamp burner device is:

[0033] First, place the quartz glass lamp tube 3 that needs to be burned (sealed) on the three-jaw chuck 2 of the lathe 1, and then place the quartz disc 15 for burning (sealing) on ​​the inner circumference of the end of the quartz glass lamp tube 3. The three-jaw chuck 2 clamps the quartz glass lamp tube 3 and provides a rotational force. At this time, push the firing slide 5 to the bottom of the burning end (sealing end) of the quartz glass lamp tube 3. When the height of the flame spray gun 16 needs to be adjusted, the handwheel 10 can be rotated to lift the lifting plate 6, so that the flame spray gun 16 fixed on the lifting plate 6 is close to the burning end of the quartz glass lamp tube 3, and the flame spray gun 16 can be adjusted by the flame spray gun 1 6. The burnt end of the quartz glass lamp tube 3 is heated. When the burnt end of the quartz glass lamp tube 3 and the quartz disc 15 placed on the inner circumference are heated to a red state, the flame spray gun 16 can be closed, and the reinforcement slide 11 can be pushed to the bottom of the quartz glass lamp tube 3, so that the end surface of the abutment plate 14 contacts the burnt end of the quartz glass lamp tube 3 in a nearly molten state, so that the burnt end of the quartz glass lamp tube 3 is pressed and reinforced, so that the inner circumference of the burnt end of the quartz glass lamp tube 3 is in close contact with the outer circumference of the quartz disc 15. After the quartz glass lamp tube 3 is cooled naturally, the burnt end operation of the quartz glass lamp tube 3 can be completed;

[0034] The quartz glass lamp tube 3 is burned by the quartz glass lamp tube burning device. On the one hand, there is no need to hold the flame spray gun 16, which ensures the safety of the operator. On the other hand, the position of the flame spray gun 16 remains unchanged, which makes the end of the quartz glass lamp tube 3 heated more evenly and is not prone to cracking. While reducing the damage rate, it also improves production capacity.
