Description

Technical Field

[0001] This utility model relates to the field of quartz glass processing technology, and in particular to a burner cutting and repair clamping fixture. Background Technology

[0002] In the production of quartz glass, a specially designed oxyhydrogen flame burner is required for the hydrolysis reaction. For example, a Chinese utility model (title: "A High-Efficiency Burner for Producing Large-Size Quartz Glass", authorization announcement number: CN216273732U, authorization announcement date: 20220412) discloses a high-efficiency burner for producing large-size quartz glass, comprising: a feeding assembly, a protective gas assembly, an oxygen supply assembly, a hydrogen supply assembly, and a protective gas assembly; the feeding assembly has a straight tubular feeding pipe, the inside of which is a through-flow channel, and the end of the channel is a frustum-shaped cone with a gradually decreasing inner diameter, the cone angle α of which is 2~30°, and the height H of which is 3~20mm.

[0003] Burners inevitably suffer varying degrees of damage after prolonged use, especially at the gas outlet face. Due to the generally high unit price and long manufacturing cycle of burners, they are often repaired by cutting to increase reusability and reduce production costs. However, since burners are mostly constructed from multiple welded glass tubes of different diameters, vibration damage is highly likely to occur during the cutting and repair process. Furthermore, the hydrolysis reaction process requires a high degree of flatness at the gas outlet face, thus necessitating the development of a tooling to ensure effective cutting and repair.

[0035] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0036] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0037] Figure 1 This is a front view of the burner cutting and repair clamping fixture in the embodiment. Figure 2 This is a top view of the burner cutting and repair clamping fixture in the embodiment. Figure 3 This is a right view of the burner cutting and repair clamping fixture in the embodiment. Figure 4 This is a three-dimensional structural diagram of the burner cutting and repair clamping fixture in the embodiment. Figure 5 This is an exploded view of the burner cutting and repair clamping fixture in the embodiment. Figures 1-5 As shown, the burner cutting and repair clamping fixture includes a base 100 that is generally rectangular in shape. The base 100 can be made of metal materials (such as stainless steel) and has a large self-weight, which can provide a good stable foundation for the burner cutting and repair clamping fixture as a whole and prevent it from tipping over. A set of first threaded holes 110 are respectively opened on both sides of the wide side of one side of the base 100, and each set of first threaded holes 110 includes two first threaded holes 110.

[0038] like Figures 1-5As shown, the burner cutting and repair clamping fixture also includes a T-shaped support 200. A set of first light holes 210 are provided on both sides of the horizontal portion of the T-shaped support 200, and each set of first light holes 210 includes two first light holes 210, the positions of which correspond one-to-one with the positions of the first threaded holes 110. Two sets of second light holes 220 are provided on the vertical portion of the T-shaped support 200, one above the other, and each set of second light holes 220 includes two second light holes 220. Therefore, when the T-shaped support 200 is placed on the base 100, by providing corresponding first bolts 230 within the mating first light holes 210 and first threaded holes 110, the T-shaped support 200 and the base 100 are connected as a whole, and the vertical portion of the T-shaped support 200 is approximately perpendicular to the base 100.

[0039] like Figures 1-5 As shown, the burner cutting and repair clamping fixture also includes two fixing clamps 300. A set of second threaded holes 310 are formed from one end face of the fixing clamp 300 facing the T-shaped support 200. Each set of second threaded holes 310 includes two second threaded holes 310, and the positions of the second threaded holes 310 correspond one-to-one with the positions of the second smooth holes 220. Therefore, by setting corresponding second bolts 320 in the mating second threaded holes 310 and second smooth holes 220, the two fixing clamps 300 can be connected to the T-shaped support 200 respectively, and the two fixing clamps 300 can fix different positions near the gas outlet end of the burner, exposing the gas outlet end face of the burner.

[0040] In this embodiment, when the gas outlet end face of the burner is cut and repaired using a wire cutting machine, the fixing clamp 300 can keep the position of the burner relatively fixed, which can reduce the probability of vibration damage. At the same time, the burner is restricted by the fixing clamp 300, which helps to ensure that the flatness of the gas outlet end face of the burner meets the requirements of the hydrolysis reaction. Furthermore, the base 100, the T-shaped support 200 and the fixing clamp 300 are detachable structures, which are convenient to disassemble and assemble. When the size of the burner is different, different fixing clamps 300 can be replaced, which has a wide range of applications.

[0041] It should be noted that in this embodiment, a single fixing clip 300 can also be used to fix the burner; preferably, the fixing effect is better when two or more fixing clips 300 are used to fix different positions of the burner respectively.

[0042] Furthermore, in this embodiment, after the burner is fixed by the fixing clamp 300, the axial center of the burner is perpendicularly coincident with the center of gravity of the base 100. That is, after the burner is fixed, its whole body is roughly perpendicular to the base 100. As a result, the burner cutting and repair clamping tool and the fixed burner are not easy to tip over.

[0043] Furthermore, such as Figure 5 As shown, the fixing clamp 300 includes a connecting part 330, a first semi-circular arc fixing part 340, and a second semi-circular arc fixing part 350. One end of the connecting part 330 is integrally formed with the first semi-circular arc fixing part 340, and the other end of the connecting part 330 is connected to the T-shaped support member 200 through a second bolt 320. The first semi-circular arc fixing part 340 and the second semi-circular arc fixing part 350 are respectively formed with a first ear plate 341 and a second ear plate 351 at both ends in the arc length direction. The first ear plate 341 and the second ear plate 351 are respectively provided with corresponding third threaded holes 342 and third smooth holes 352. By setting corresponding third bolts 360 in the mating third threaded holes 342 and third smooth holes 352, the first semi-circular arc fixing part 340 and the second semi-circular arc fixing part 350 can be quickly assembled to form a hollow tubular structure for supporting and fixing the burner.

[0044] Furthermore, such as Figure 5 As shown, a first rubber pad 343 and a second rubber pad 353 are laid on the arc-shaped inner walls of the first semi-circular arc fixing part 340 and the second semi-circular arc fixing part 350; the first rubber pad 343 and the second rubber pad 353 can avoid wear, cracking and other defects caused by the first semi-circular arc fixing part 340 and the second semi-circular arc fixing part 350 directly contacting the burner.

[0045] Furthermore, such as Figure 5 As shown, a groove 240 is provided at the connection position between the vertical part of the T-shaped support 200 and the fixing clip 300. One end of the fixing clip 300 is inserted into the groove 240 and then fixed by the second bolt 320. The groove 240 can realize the quick positioning of the fixing clip 300 and also provide support for the fixing clip 300, reducing the pressure on the second bolt 320.

[0046] Furthermore, such as Figure 5 As shown, the burner cutting and repair clamping fixture also includes a buffer pad 400; the buffer pad 400 is laid on the upper surface of the base 100; thus, the buffer pad 400 can provide temporary cushioning during the burner fixing process.
