Description

Technical Field

[0001] This utility model relates to the field of quartz tube stand technology, and in particular to a stand for surface treatment of quartz tubes. Background Technology

[0002] During processing (such as high-temperature forming, cutting, and chamfering), quartz tubes may develop defects such as white spots, scratches, burrs, stains, or uneven oxide layers. Polishing can directly remove these surface imperfections, resulting in a smooth and clean surface that meets the stringent appearance requirements of optics and precision instruments. Polishing can also correct localized protrusions or depressions caused by uneven temperature and pressure during processing, ensuring a smooth overall appearance without visible defects, making it particularly suitable for appearance-sensitive applications. When polishing quartz tubes, a support or stand is required to hold the tube and rotate it during polishing to adjust and change the polishing surface.

[0003] While existing quartz tube supports have solved some problems, they primarily employ a V-shaped top with rollers installed within the V-shaped grooves to hold the quartz tube in place, or coaxial rollers directly mounted on the worktable, using two sets of coaxial rollers to support the quartz tube and ensure its rotation. However, quartz tubes come in various specifications depending on their length and diameter, and the spacing between the rollers can result in uneven contact with different parts of the quartz tube's exterior, or even none at all. Furthermore, when quartz tubes of different lengths are placed on the support, the uneven distribution of the roller support points affects the stability of rotation during grinding; the supports also lack adaptability for placing quartz tubes of different specifications. Utility Model Content

[0004] This utility model provides a stand for surface treatment of quartz tubes, which solves the defects of the prior art, such as the inconvenience of adjusting the spacing between rollers on the stand according to the thickness of the quartz tube, the uneven distribution of the support points of the rollers when quartz tubes of different lengths are placed on the stand, which affects the stability of the rotation during the grinding of the quartz tube, and the poor applicability of the stand to quartz tubes of different specifications.

[0005] This utility model provides a stand for surface treatment of quartz tubes, comprising:

[0006] A platform, with several evenly distributed mounting seats fixedly connected to its top, each mounting seat having several pivot slots on its top; two pivots, each pivot detachably mounted in a pivot slot, each pivot surface having several evenly distributed positioning grooves, wherein the distance between the two pivots is adjusted by engaging one of the pivots in different pivot slots; a support member, comprising several rollers evenly distributed on the pivots, each roller having two positioning sleeves inside, the positioning sleeves being used to position the rollers in preset positioning grooves; and a control component, disposed between the positioning sleeves and the rollers, the control component being used to control the opening and closing of the positioning sleeves.

[0007] Optionally, the roller has two symmetrically arranged cavities inside, and the roller is fitted onto the rotating shaft through a central circular hole, with the cavities and the central circular hole of the roller communicating with each other.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] As mentioned earlier, current support brackets are mainly V-shaped at the top, with rollers installed in the V-shaped grooves to hold the quartz tube in place, or coaxial rollers are directly installed on the table, using two sets of coaxial rollers to support the quartz tube and ensure its rotation. However, quartz tubes come in various specifications depending on their length and diameter. The spacing between the rollers can cause them to contact different parts of the quartz tube's exterior, or even fail to contact it at all. Furthermore, when quartz tubes of different lengths are placed on the support bracket, the support points of the rollers are unevenly distributed, affecting the stability of the quartz tube's rotation during polishing. The support brackets also have poor applicability to quartz tubes of different specifications.

[0027] To address this issue, this utility model provides a stand for quartz tube surface treatment. The stand allows adjustment of the distance between two rotating shafts 2 according to the thickness of the quartz tube via the rotating shaft slot 6 on the mounting base 5. This ensures the stand can accommodate and support quartz tubes of various thicknesses. By opening and closing the positioning sleeve 8, rollers 3 are positioned in different positioning slots 7. Adjusting the distance between rollers 3 on the same rotating shaft 2 further allows the stand to adjust the support position according to quartz tubes of different lengths, ensuring uniform distribution of support points and increasing its applicability to different types of quartz tubes. The stand is easy to adjust and its structure facilitates operation.

[0028] The following is combined Figures 1-6 This utility model is described in detail. Example

[0029] like Figures 1-6 As shown, this utility model provides a stand, especially a stand for surface treatment of quartz tubes, including a stand 1, a rotating shaft 2, rollers 3, a control component 4, a mounting base 5, and positioning sleeves 8 symmetrically arranged inside the central circular hole of the rollers 3.

[0030] Among them, the stand 1 serves as the main body of the stand for this type of quartz tube surface treatment, such as... Figures 1-3 As shown, a mounting base 5 is bolted to both ends and the middle of the upper surface of the platform 1. Several evenly distributed swivel slots 6 are formed on the top of the mounting base 5, such as... Figure 3As shown, one pivot groove 6 is provided on one side of the mounting base 5, and several are provided on the other side. Two pivots 2 are mounted on these three mounting bases 5 via the pivot grooves 6. The pivots 2 are locked inside the pivot grooves 6 and can rotate. By locking one pivot 2 inside different two pivot grooves 6, the distance between the two pivots 2 can be adjusted. This ensures that the quartz tubes of different thicknesses can be stably placed on this type of stand during surface polishing. For thicker quartz tubes, the distance between the two pivots 2 can be increased; for thinner quartz tubes, the distance can be decreased.

[0031] Quartz tubes of different specifications not only differ in length but also in shape. Therefore, this invention proposes adjustable rollers 3 to adjust the distance between rollers 3 according to the length of the quartz tube, ensuring a uniform distribution of the rollers 3 on the outer wall of the quartz tube. Several evenly distributed positioning grooves 7 are formed on the surface of the rotating shaft 2. These positioning grooves 7 are annular. Several evenly distributed rollers 3 are fitted onto the rotating shaft 2. In this embodiment, three rollers 3 are used as an example. Each roller 3 is fitted onto the rotating shaft 2 through a central hole, and each roller 3 has two symmetrically arranged positioning sleeves 8 in its central hole. The thickness of the positioning sleeves 8 is the same as the width of the positioning groove 7. When the two positioning sleeves 8 are closed, they form a complete ring, which fits perfectly onto the positioning groove 7 on the rotating shaft 2, thus enabling the positioning of different rollers 3 in different positions within the positioning groove 7.

[0032] When the two positioning sleeves 8 move away from each other, they can both leave the interior of the positioning groove 7, ensuring that the positioning groove 7 does not obstruct the movement of the roller 3. To facilitate control of the positioning sleeves 8, a control component 4 is provided between the positioning sleeves 8 and the roller 3. The control component 4 mainly includes a lever 401, a latch 402, a telescopic rod 403, and a return spring 404. Two symmetrical cavities 9 are formed inside each roller 3. Slots 10 are formed on both sides of the cavity 9 along the axial direction of the rotating shaft 2. The levers 401 are all located inside the cavities 9. Figure 5 As shown, the toggle blocks 401 are fixedly connected to the side of the positioning sleeve 8 that is far away from each other. A lug 402 is fixedly connected to both sides of the toggle blocks 401 along the axial direction of the rotating shaft 2. The lug 402 extends from the inside of the slot 10 to the outside of the roller 3, so that the toggle blocks 401 can be controlled to move closer or further apart, thereby causing the positioning sleeve 8 to leave the locking state of the roller 3 on the rotating shaft 2 inside the positioning groove 7.

[0033] To facilitate the automatic engagement of the positioning sleeve 8 into the corresponding positioning groove 7 on the rotating shaft 3 after the roller 3 moves to the inside, thus positioning the roller 3, a telescopic rod 403 is fixedly connected to the side of the lever 401 that is far apart from each other. A return spring 404 is sleeved on the outside of the telescopic rod 403. The return spring 404 uses its own elasticity to press the lever 401 towards each other. The telescopic end of the telescopic rod 403 is fixedly connected to the side of the cavity 9 that is far from the rotating shaft. The telescopic rod 403 guides the extension and retraction of the return spring 404, and the elasticity of the return spring 404 keeps the two positioning sleeves 8 always tending to move closer to each other, facilitating automatic engagement into the positioning groove 7. To reduce contact wear between the roller 3 and the surface of the quartz tube, a rolling rubber ring 13 is sleeved on the outside of each roller 3. The rolling rubber ring 13 is rotatably connected to the roller 3 through a bearing.

[0034] The quartz tube is placed between two rolling rubber rings 13 on both sides. The rollers 3 on the two rotating shafts 2 are asymmetrically arranged to increase the distribution of support points on the surface of the quartz tube. After the quartz tube is processed, due to uneven heat treatment or chemical reaction residue, white compound spots or marks may remain on the surface. These require polishing with a grinding machine to improve the surface precision and facilitate subsequent processing. During polishing, the quartz tube needs to rotate automatically. The cylindrical side of the quartz tube should be carefully observed. The surface of the quartz tube is rinsed with filtered pure water while being polished with the grinding machine.

[0035] When quartz tubes have different sizes, such as different thicknesses, the distance between the two rotating shafts 2 is adjusted according to the thickness of the quartz tube. This is achieved by moving one of the rotating shafts into different rotating shaft slots 6, which facilitates stable support of the platform for quartz tubes of different thicknesses. When the quartz tubes have different lengths, the latches 402 are moved apart according to the length of the quartz tube, causing the positioning sleeve 8 to leave the interior of the positioning groove 7, and the rollers 3 are moved into other positioning grooves 7. This adjusts the distance between different rollers 3 on the same rotating shaft 2, ensuring a uniform distribution of support points of the rollers 3 on the surface of the quartz tube. Example

[0036] Based on Embodiment 1, in order to further collect the pure water used for polishing quartz tubes for easy reuse, this embodiment provides a water collection tank 11 at the bottom of the inner side of the frame 1. Several evenly distributed scraping grooves 12 are formed on the inner wall of the water collection tank 11. The bottom of the water collection tank 11 is higher in the middle and lower at both ends, allowing the water inside the tank to flow out at both ends after collecting the wastewater used for polishing. Figure 3As shown, both ends of the water collection tank 11 are fixedly connected to drain pipes to facilitate the transportation of collected wastewater. During the process of water being discharged from inside the water collection tank 11, the grinding debris flows into the water collection tank 11 along with the water flow. When the wastewater is discharged to the outside of both ends of the water collection tank 11, the debris that settles at the bottom of the wastewater is intercepted by the scraper 12 due to the obstruction of the scraper 12, leaving only the wastewater with a small amount of debris to be discharged outward, reducing the external load on the wastewater recycling filter and extending the filter cleaning cycle.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
