[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1-10 , the present invention provides the following technical solutions:

[0042] Example 1: A quartz tube flange side positioning device includes a quartz tube body 1 and a positioning platform 2. The quartz tube body 1 is located above the positioning platform 2. The side of the positioning platform 2 is connected to a quartz tube fixing structure 3 and a connecting structure 5. An adjustment structure 4 is installed on the outside of the connecting structure 5. The inside of the adjustment structure 4 is connected to a flange fixing structure 6. A flange body 8 is provided inside the flange fixing structure 6. A rotating structure 7 is connected below the positioning platform 2.

[0043] The positioning platform 2 includes a platform body 201, a connecting groove 202, a first limiting groove 203 and a second limiting groove 204. The side of the platform body 201 is provided with the second limiting groove 204, the connecting groove 202 and the first limiting groove 203 from top to bottom.

[0044] like Figures 1-4 and Figure 6 As shown, the quartz tube fixing structure 3 includes a clamping plate 301, a fixing plate 302, a first spring 303, a placement plate 304, a pulling plate 305 and a fixing screw 306. Three placement plates 304 are provided on the top of the platform 201. The top of the placement plate 304 is slidably connected to the clamping plate 301. The top of the clamping plate 301 is fixedly connected to the pulling plate 305. Holding the pulling plate 305 of one side of the quartz tube fixing structure 3 and pulling it outwards, it drives the clamping plate 301 to move outwards.

[0045] The first spring 303 is connected between the clamping plate 301 and the fixing plate 302. The first spring 303 is used to push the clamping plate 301 to push the quartz tube body 1 in other directions, thereby pushing the other positions of the quartz tube body 1 to the top of the placing plates 304 on the other two sides. The elastic force of the first spring 303 is strong, and each elastic force is the same, so that the quartz tube fixing structure 3 can firmly clamp the quartz tube body 1 in the middle of the table 201. You can also directly hold the three pulling plates 305 and pull them outward to place the quartz tube body 1 directly in the middle of the table 201, and at the same time release the three pulling plates 305 to fix it.

[0046] The fixing plate 302 is internally threaded with a fixing screw 306. An annular second limiting groove 204 is provided on the upper side of the platform 201. The fixing screw 306 is manually screwed so that its tail end abuts against the second limiting groove 204, thereby fixing the fixing plate 302 and thus the quartz tube fixing structure 3. The fixing screw 306 is reversely screwed out so that its tail end leaves the second limiting groove 204, and the structure can be disassembled or moved on the platform 201.

[0047] like Figure 1-Figure 5 and Figure 8 As shown, the flange fixing structure 6 includes a first positioning block 601, a limiting plate 602, a pad 603, a second positioning block 604, a second spring 605, a pressing plate 606, a long screw 607 and a nut 608. The first positioning block 601 and the second positioning block 604 are provided with grooves. After the quartz tube body 1 is fixed, the first positioning block 601 is fixedly installed on the inner side of the moving block 404. The pad 603 is fixedly installed in the groove wall of the first positioning block 601. The flange body 8 is passed through the moving block 404 and placed on the top of the pad 603. Then the second positioning block 604 is placed on the top of the flange body 8. The second spring 605 is fixedly connected to the second positioning block 604. The second spring 605 is away from the first One end of the second positioning block 604 is fixedly connected to a pressure plate 606, so that the pressure plate 606 presses the flange body 8, so that the pad 603 and the pressure plate 606 clamp and fix it. The left and right sides of the first positioning block 601 and the second positioning block 604 are fixedly connected to the limiting plates 602. At this time, the hole pieces of the upper and lower limiting plates 602 are aligned, and the long screw 607 is inserted. Use the nut 608 to screw the long screw 607 from the bottom part of the limiting plate 602 of the first positioning block 601 and screw it upward until the flange body 8 is firmly limited. Since the first positioning block 601 is a separate part, it cooperates with the second spring 605 to enable the flange fixing structure 6 to clamp and fix flange bodies 8 of different sizes.

[0048] like Figure 1-Figure 5 As shown, the adjustment structure 4 includes a first motor 401, a screw rod 402, an auxiliary rod 403, a moving block 404 and a mounting plate 405. After the flange fixing structure 6 fixes the flange body 8, the controller is operated so that the first motors 401 of all the adjustment structures 4 are started in the same direction and speed. The first motor 401 is started, and the output end of the first motor 401 is fixedly connected to the screw rod 402. The first motor 401 drives the screw rod 402 to rotate. The outer side of the screw rod 402 is threadedly connected to the moving block 404, so that the rotating screw rod 402 drives the moving block 404 to move up and down, thereby driving the flange body 8 to move up and down, thereby accurately moving the position of the flange body 8. The screw rod 402 is rotatably connected to the mounting plate 405, and the mounting plate 405 is rotatably connected to the auxiliary rod 403. The outer side of the auxiliary rod 403 is slidably connected to the moving block 404, which can ensure that the moving block 404 moves steadily up and down.

[0049] like Figure 1-Figure 5 、 Figure 8 and Figure 10 As shown, the connecting structure 5 includes a "┠"-shaped plate 501, a connecting plate 502 and a connecting screw 503. The outer side of the horizontal plate of the "┠"-shaped plate 501 is fixedly connected to the mounting plate 405 by screws, and a plurality of screw holes are provided in the horizontal plate of the "┠"-shaped plate 501. The adjusting structure 4 can be easily disassembled and assembled by twisting the screws. The screw holes at other positions on the horizontal plate of the "┠"-shaped plate 501 can be selected for fixing, thereby adjusting the position of the flange fixing structure 6, thereby improving the stability of the flange body 8. The middle part and the bottom of the side of the platform 201 are respectively provided with an annular connecting groove 202 and an annular first limiting groove 203. The vertical plate of the "┠"-shaped plate 501 is slidably connected in the connecting groove 202. Pushing and pulling the "┠"-shaped plate 501 moves the position of the connecting structure 5, thereby moving the position of the fixing structure 6 and adjusting the angle between the three fixing structures 6.

[0050] The connecting plate 502 is fixedly connected to the bottom of the horizontal plate of the "┠"-shaped plate 501 and the outer bottom of the mounting plate 405, respectively. The connecting screw 503 is threadedly connected to the connecting plate 502. The handle of the connecting screw 503 is held so that the tail end of the connecting screw 503 rests on the wall of the first limiting groove 203 to fix the "┠"-shaped plate 501, thereby fixing the flange fixing structure 6. The inner walls of the first limiting groove 203 and the second limiting groove 204 are relatively rough, so the fixation is relatively stable.

[0051] Example 2: Figure 1-Figure 5 and Figure 7 As shown, the rotating structure 7 includes a rotating base 701, a second motor 702, a connecting platform 703 and a rotating platform 704. The connecting platform 703 is fixedly connected to the rotating platform 704 by screws. The connecting platform 703 and the rotating platform 704 can be disassembled by turning the screws. The top of the rotating platform 704 is fixedly connected to the platform body 201, thereby facilitating the disassembly of the platform body 201.

[0052] During the welding process, the second motor 702 can be started. The second motor 702 is fixedly installed in the rotating base 701. The output end of the second motor 702 is fixedly connected to the connecting platform 703. The second motor 702 drives the connecting platform 703 to rotate, which drives the rotating platform 704 to rotate, which drives the platform body 201, thereby facilitating the welding of each flange body 8. There is no need for workers to move for welding, which further improves the welding efficiency.

[0053] The components of this side positioning device are all made of high-temperature resistant materials, and the surface of the components is coated with high-temperature resistant paint, thereby extending the service life of the device; the backing plate 603 and the pressure plate 606 are made of high-temperature resistant elastic materials to prevent the first positioning block 601 and the second positioning block 604 from causing wear on the flange body 8. The hole provided in the movable block 404 is large enough to pass through the flange plate 8 of common sizes;

[0054] Working principle: First install and connect all parts, use the quartz tube fixing structure 3 to fix the quartz tube body 1, install the flange body 8 in the flange fixing structure 6, use the adjustment structure 4 to accurately adjust the position of the flange body 8, and finally weld, using the rotating structure 7 for assistance to improve welding efficiency.
