Description

Technical Field

[0001] The invention belongs to the technical field of quartz processing, and in particular relates to an online monitoring type quartz tube diameter-changing amplification device. Background Art

[0002] During the quartz tube processing process, the diameter of the quartz tube is changed through heating and stretching to achieve expansion. This device is often used in conjunction with a sensor to enable online monitoring of the tube's diameter change. The variable diameter expansion device primarily consists of a drive mechanism, a heating mechanism, and an expansion mechanism. The heating mechanism heats and softens the quartz tube, while the drive mechanism rotates the tube, causing the softened portion to expand outward under the action of centrifugal force, achieving variable diameter expansion.

[0003] In the use of the existing online monitoring type quartz tube variable diameter expansion device, a supporting wheel is generally set on the outside of the quartz tube to limit the diameter size of the quartz tube after the tube is expanded. However, the supporting wheel only limits the quartz tube from the outside, which easily leads to uneven diameter size of the inner wall of the quartz tube. Some devices set a rotating roller on the inside of the quartz tube and a sleeve for limiting the diameter on the outside of the quartz tube. The quartz tube is limited from the inside and outside of the quartz tube by the rotating roller and the sleeve. Although the uniformity of the inner wall of the quartz tube is improved, the sleeve with a fixed size is only suitable for quartz tubes of one diameter size, and the adaptability is insufficient. For quartz tubes with a longer length, the rotating roller needs to move a longer distance, and it is difficult for the rotating roller to move from one end of the quartz tube to the other end. The rotating roller needs to be extended into the inner side of the quartz tube from both ends in two times to expand the two ends of the quartz tube respectively, and the convenience of quartz tube expansion is insufficient. Summary of the Invention

[0004] The purpose of the present invention is to provide an online monitoring type quartz tube variable diameter expansion device, which can limit the inner and outer sides of the quartz tube respectively through the inner expansion mechanism and the outer expansion mechanism, and adapt to quartz tubes of different diameters by adjusting the distance between the rotating roller and the axis of the quartz tube and the distance between the supporting wheel and the axis of the quartz tube.

[0021] The technical effects achieved by the present invention are:

[0022] The present invention adopts the design of an inner expansion mechanism and an outer expansion mechanism. The inner expansion mechanism and the outer expansion mechanism can be limited by the inner and outer sides of the quartz tube respectively, so as to improve the uniformity of the diameter size of the inner wall of the quartz tube. After the driving mechanism drives the quartz tube to rotate, the quartz tube expands outward under the action of centrifugation.

The two sliding arms are detachably connected to the shaft body, which is convenient for expanding quartz tubes with longer lengths. When the shaft body and the rotating roller move from one end of the quartz tube to the other end, the shaft body is first connected to one sliding arm and then enters the inner side of the quartz tube from one end of the quartz tube. The shaft body is then connected to the other sliding arm and then leaves the other end of the quartz tube. By moving the shaft body from one sliding arm to the other sliding arm, the rotating roller can expand the longer quartz tube. Compared with the existing technology, the rotating roller is prevented from being inserted into the quartz tube twice, thereby improving the convenience of expansion.

[0024] The present invention adopts a design of several independent rotating rollers. When the radial distances between the several rotating rollers and the shaft body increase successively, the sudden expansion of the inner wall of the quartz tube is reduced, the stability of the expansion is improved, and when the radial distances between the several rotating rollers and the shaft body are equal, the rotating rollers facilitate supporting the inner wall of the quartz tube to improve the uniformity of the expansion.

[0037] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0038] Example 1: Figures 1 to 5 As shown in the figure, it is the first embodiment of the present invention. This embodiment provides an online monitoring type quartz tube variable diameter expansion device, including a body 10; a driving mechanism 20, which is arranged on the body 10 and is used to clamp the quartz tube and drive the quartz tube to rotate; an internal expansion mechanism 30, which is arranged on the body 10 and includes two sliding arms 31 slidably mounted on the body 10, and a shaft 32 is detachably mounted between the two sliding arms 31, and a plurality of rotating rollers 33 are circumferentially mounted on the shaft 32; an external expansion mechanism 40, which is arranged on the body 10 and includes a slide 41 slidably mounted on the body 10, and a support wheel 42 is rotatably mounted on the slide 41.

[0039] It should be noted that the body 10 and the driving mechanism 20 are both existing technologies. The driving mechanism 20 is provided with a clamping claw and a driving motor (not shown in the figure) for clamping the quartz tube and driving the quartz tube to rotate. The driving mechanism 20 and the slide 41 are all slidably mounted together with the body 10 through gears and racks, which will not be repeated here. The body 10 is provided with a laser ranging sensor (not shown in the figure) and a feedback control mechanism (not shown in the figure). The laser ranging sensor and the feedback control mechanism are both existing technologies and are used to measure the amplified diameter in real time for online monitoring. The body 10 is also provided with a heating mechanism (not shown in the figure). The heating mechanism is existing technology and includes a flame gun circumferentially arranged on the outside of the quartz tube for heating the quartz tube to soften the quartz tube. The rotating roller 33 and the shaft 32 are telescopically mounted together in the radial direction, and the support wheel 42 and the slide 41 are slidably mounted together in the vertical direction.

[0040] When the present invention is in use, the driving mechanism 20 clamps the quartz tube and drives the quartz tube to rotate, the rotating roller 33 limits the quartz tube from the inner side of the quartz tube, and the supporting wheel 42 limits the quartz tube from the outer side of the quartz tube, so as to improve the uniformity of the diameter size of the inner wall of the quartz tube, and the distance between the rotating roller 33 and the axis diameter of the shaft body 32 is adjusted to adjust the distance between the rotating roller 33 and the axis of the quartz tube, and the distance between the supporting wheel 42 and the axis of the quartz tube is adjusted by adjusting the height position of the supporting wheel 42, so as to adapt to quartz tubes of different diameters. Compared with the fixed-size sleeve arranged on the outer side of the quartz tube in the prior art, the applicability is improved, and when a longer quartz tube needs to be extended, a sliding arm 31 drives the shaft body 32 from one end of the quartz tube to extend into the inner side of the quartz tube, so that the rotating roller 33 is moved from one end of the quartz tube to the inner side of the quartz tube. To expand the quartz tube, when the shaft 32 drives the rotating roller 33 to move to the middle part of the quartz tube, another sliding arm 31 extends from the other end of the quartz tube into the inner side of the quartz tube, so that the sliding arm 31 is connected to the shaft 32. The shaft 32 is disassembled from the original sliding arm 31, and the shaft 32 is moved from one sliding arm 31 to the other sliding arm 31. The sliding arm 31 connected to the shaft 32 drives the shaft 32 to move toward the other end of the quartz tube, so that the rotating roller 33 expands the other end of the quartz tube, thereby facilitating the expansion of quartz tubes with longer lengths. Compared with the prior art, the rotating roller 33 enters from one end of the quartz tube and leaves from the other end, avoiding the need to extend the rotating roller 33 from both ends into the inner side of the quartz tube twice to expand the two ends of the quartz tube respectively, thereby improving the convenience of quartz tube expansion.

[0041] Example 2: Reference Figures 1 to 10 , which is the second embodiment of the present invention, and this second embodiment is based on the previous embodiment.

[0042] like Figure 5 、 Figure 6 and Figure 7As shown, a plurality of connecting plates 51 are provided on the outer side of the shaft body 32 along the circumferential direction, a telescopic scissor frame 52 is installed between the connecting plate 51 and the shaft body 32, and the rotating roller 33 is rotatably installed together with the connecting plate 51. The number of the connecting plates 51 is equal to the number of the rotating rollers 33 and corresponds one to one.

[0043] It should be noted that, in the present invention, the number of the rotating rollers 33 is preferably three, wherein the rotating roller 33 located at the bottom is aligned with the supporting wheel 42 in the vertical direction.

[0044] According to the above structure, since there are several rotating rollers 33, the rotating rollers 33 aligned with the supporting wheel 42 limit the quartz tube from the inside, and the rotating rollers 33 and the supporting wheel 42 together limit the diameter size of the inner wall of the quartz tube, thereby improving the uniformity of the diameter size of the inner wall of the quartz tube, and by adjusting the telescopic length of the corresponding telescopic scissors frame 52 to adjust the radial distance between the rotating roller 33 and the shaft body 32, if the radial distance between several rotating rollers 33 and the shaft body 32 is adjusted to increase successively along the rotation direction of the quartz tube, it is convenient for the diameter size of the inner wall of the quartz tube to gradually expand outward, reducing the situation where the inner wall of the quartz tube suddenly expands when passing through the rotating roller 33 due to a single rotating roller 33, thereby improving the stability of the expansion, and if the radial distance between several rotating rollers 33 and the shaft body 32 is adjusted to the same size, it is convenient for the rotating rollers 33 that are not aligned with the supporting wheel 42 to support the inner wall of the quartz tube, thereby improving the uniformity of the expansion.

[0045] like Figure 5 、 Figure 6 and Figure 7 As shown, the telescopic scissors frame 52 includes a first telescopic rod 61 fixedly connected to the shaft body 32, and the output end of the first telescopic rod 61 is fixedly connected to a slide plate 62, and the slide plate 62 is slidably connected to the shaft body 32 along the axial direction, and a first scissors rod 63 is rotatably connected between the slide plate 62 and the connecting plate 51, and a second scissors rod 64 is arranged between the shaft body 32 and the connecting plate 51, one end of the second scissors rod 64 is rotatably connected to the shaft body 32, and the other end of the second scissors rod 64 is slidably installed together with the connecting plate 51, and the first scissors rod 63 is rotatably connected to the second scissors rod 64.

[0046] It should be noted that the first telescopic rods 61 are preferably telescopic electric rods in the present invention. The number of the first telescopic rods 61 is equal to the number of the rotating rollers 33 and they are distributed along the circumference of the shaft 32 .

[0047] According to the above structure, after the first telescopic rod 61 works, the output end drives the slide plate 62 to move along the axial direction of the shaft body 32, and the slide plate 62 drives the first scissors rod 63 and the second scissors rod 64 to rotate, and the end of the second scissors rod 64 close to the connecting plate 51 slides along the connecting plate 51, so that the end of the first scissors rod 63 and the second scissors rod 64 close to the connecting plate 51 drives the rotating roller 33 to move radially along the shaft body 32 through the connecting plate 51, so as to facilitate the adjustment of the radial distance between the rotating roller 33 and the shaft body 32. It not only adapts to quartz tubes of different diameters and improves applicability, but also facilitates the improvement of the stability and uniformity of amplification by adjusting the radial distance between several rotating rollers 33 and the shaft body 32.

[0048] like Figure 5 、 Figure 6 and Figure 7 As shown, the second scissor rod 64 is rotatably connected to one end of the connecting plate 51 with a sliding rod 65, and the top of the connecting plate 51 is fixedly connected to a first sliding groove 66. The sliding rod 65 slides in cooperation with the first sliding groove 66, and a first nut 67 is provided on the outside of the first sliding groove 66. The end of the first nut 67 fits in cooperation with the outside of the first sliding groove 66, and the first nut 67 is threadedly connected to the end of the sliding rod 65.

[0049] According to the above structure, the slide rod 65 cooperates with the first slide groove 66, so that the process of the second scissor rod 64 sliding along the connecting plate 51 near one end of the connecting plate 51 is more stable. The first nut 67 is threadedly connected to the slide rod 65, which facilitates the disassembly between the slide rod 65 and the first slide groove 66. The end of the first nut 67 fits against the outer side of the first slide groove 66, which facilitates the limiting of the slide rod 65 and the first slide groove 66 by the two ends of the slide rod 65, reducing the deflection of the slide rod 65 on the inner side of the first slide groove 66, making the sliding process of the slide rod 65 along the first slide groove 66 more stable.

[0050] like Figure 5 and Figure 6 As shown, a second slide groove 71 is provided on the slide plate 62, and a first slide bar 72 is fixedly connected to the shaft body 32. The second slide groove 71 and the first slide bar 72 slide together along the axial direction of the shaft body 32. A limiting ring 73 is provided at the end of the first slide bar 72. The limiting ring 73 slides together with the shaft body 32. A bolt 74 is slidably connected to the limiting ring 73, and the end of the bolt 74 is threadedly connected to the shaft body 32.

[0051] It should be noted that the number of the first slide bars 72 is equal to the number of the slide plates 62 and they are distributed along the circumference of the shaft body 32 . The cross-sectional shapes of the second slide grooves 71 and the first slide bars 72 are both dovetail-shaped.

[0052] The second slide groove 71 cooperates with the first slide bar 72 to make the sliding process of the slide plate 62 along the shaft body 32 more stable. The limiting ring 73 arranged at the end of the first slide bar 72 prevents the slide plate 62 from continuing to slide along the second slide groove 71 to avoid the slide plate 62 from being separated from the shaft body 32. Moreover, since the limiting ring 73 is detachably connected to the shaft body 32 by bolts 74, it is convenient to remove the limiting ring 73 so that the slide plate 62 can slide out along the second slide groove 71, thereby improving the convenience of disassembly and assembly.

[0053] like Figure 6 and Figure 7 As shown, the interior of the rotating roller 33 is slidably connected to a connecting rod 53, and the connecting rod 53 is slidably connected to the connecting plate 51. One end of the connecting rod 53 is fixedly connected to a stopper 54, and the inner side of the stopper 54 fits in with the connecting plate 51. The other end of the connecting rod 53 is threadedly connected to a second nut 55, and the end of the second nut 55 fits in with the connecting plate 51.

[0054] It should be noted that the connecting rod 53 and the rotating roller 33 are also rotationally matched.

[0055] According to the above structure, when it is necessary to disassemble the rotating roller 33, the second nut 55 is removed from the end of the connecting rod 53, and the connecting rod 53 is pulled out from the inside of the connecting plate 51 and the rotating roller 33, so that the limitation on the rotating roller 33 is released, thereby removing the rotating roller 33. When it is necessary to install the rotating roller 33, the connecting rod 53 is inserted into the connecting plate 51 and the rotating roller 33, so that the inner side of the stopper 54 is in contact with the connecting plate 51, and the second nut 55 is installed at the end of the connecting rod 53 away from the stopper 54, so that the end of the second nut 55 is in contact with the connecting plate 51. At this time, the stopper 54 and the second nut 55 limit the rotating roller 33 and the connecting plate 51 in the axial direction, so that the rotating roller 33 is installed on the connecting plate 51, thereby facilitating the disassembly and assembly of the rotating roller 33.

[0056] like Figure 1 、 Figure 4 and Figure 8 As shown, two sliding shells 81 are slidably installed on the body 10, the sliding arm 31 is slidably connected to the sliding shell 81 in the horizontal direction, the sliding shell 81 is fixedly connected to the first motor 82, the output end of the first motor 82 is fixedly connected to the first gear 83, and the sliding arm 31 is fixedly connected to the first rack 84 along the axial direction, and the first gear 83 and the first rack 84 are meshed.

[0057] It should be noted that the sliding shell 81 and the body 10 are slidingly installed together through gears and racks. This transmission method is an existing mature technology and will not be described in detail here. A second slide bar is fixedly connected to the sliding arm 31, and a third slide groove is provided on the sliding shell 81. The second slide bar and the third slide groove slide in cooperation to avoid relative rotation between the sliding arm 31 and the sliding shell 81, thereby making the sliding process of the sliding arm 31 along the sliding shell 81 more stable.

[0058] According to the above structure, after the first motor 82 works, the output end drives the first gear 83 to rotate, and the first gear 83 drives the sliding arm 31 to move along the sliding shell 81 through the first rack 84, so that the sliding arm 31 drives the shaft 32 to extend into the inner side of the quartz tube or be pulled out from the inner side of the quartz tube.

[0059] like Figure 5 and Figure 9 As shown, both ends of the shaft body 32 are fixedly connected with a cavity 85, and the cavity 85 is slidably connected to the end of the sliding arm 31. A limiting block 86 is slidably connected to the inner wall of the cavity 85 in the radial direction. A limiting hole 87 is opened at the end of the sliding arm 31, and the upper end of the limiting block 86 slides with the limiting hole 87. The end of the sliding arm 31 is fixedly connected with a second telescopic rod 88, and the output end of the second telescopic rod 88 is fixedly connected with a push block 89, and the push block 89 abuts and cooperates with the lower end of the limiting block 86.

[0060] It should be noted that the bottom of the limit block 86 and the top of the push block 89 are both inclined surfaces and fit together. The width of the lower end of the limit block 86 is smaller than the width of the upper end of the limit block 86, and a convex edge is fixedly connected to the inner wall of the cavity 85 near the lower end of the limit block 86, which is used to prevent the upper end of the limit block 86 from continuing to move downward to avoid the limit block 86 from separating from the cavity 85.

[0061] According to the above structure, when it is necessary to connect the slide arm 31 and the shaft body 32 together, the end of the slide arm 31 is brought close to the end of the shaft body 32 so that the cavity 85 is inserted into the end of the slide arm 31. At this time, the limit block 86 is aligned with the limit hole 87. After the second telescopic rod 88 works, the output end drives the push block 89 to move. The push block 89 pushes the limit block 86 to move upward along the radial direction of the cavity 85, so that the upper end of the limit block 86 is inserted into the limit hole 87, limiting the cavity 85 and the slide arm 31, thereby connecting the slide arm 31 and the shaft body 32 together. When the slide arm 31 is disassembled from the shaft body 32, the output end of the second telescopic rod 88 drives the push block 89 to move after operation, so that the push block 89 moves away from the limit block 86. The limit block 86 moves downward along the radial direction of the cavity 85 under the action of its own gravity, so that the upper end of the limit block 86 is disengaged from the limit hole 87, and the limit of the cavity 85 and the slide arm 31 is released. The slide arm 31 is moved to the side away from the shaft body 32, so that the cavity 85 is pulled out from the end of the slide arm 31, so that the slide arm 31 and the shaft body 32 are disassembled, thereby facilitating the disassembly and assembly of the slide arm 31 and the shaft body 32.

[0062] like Figure 10 As shown, the outward expansion mechanism 40 further includes a water tank 91 slidably mounted on the slide 41 along the vertical direction, and the supporting wheel 42 is rotatably connected to the water tank 91.

[0063] It should be noted that a water inlet (not shown in the figure) and a water outlet (not shown in the figure) are provided on the water tank 91, and a cooling system (not shown in the figure) is provided outside the water tank 91. The water inlet and the water outlet are both connected to the cooling system, which is used to circulate the water in the water tank 91 to cool the support wheel 42.

[0064] According to the above structure, the water tank 91 slides up and down along the slide 41, driving the supporting wheel 42 to slide up and down in the vertical direction, thereby facilitating the adjustment of the distance between the supporting wheel 42 and the axis of the quartz tube, adapting to quartz tubes of different diameters, and improving applicability.

[0065] like Figure 10 As shown, the water tank 91 is slidably connected to the slide 41 along the vertical direction, and a telescopic cylinder 92 is fixedly connected to the slide 41 , and the output end of the telescopic cylinder 92 is fixedly connected to the water tank 91 .

[0066] It should be noted that a linear guide rail is provided between the water tank 91 and the slide 41 , and the water tank 91 and the slide 41 are slidably connected via the guide rail. The telescopic cylinder 92 is preferably a telescopic hydraulic cylinder in the present invention.

[0067] According to the above structure, after the telescopic cylinder 92 works, the output end drives the water trough 91 to move up and down along the slide 41, and the water trough 91 drives the supporting wheel 42 to move up and down, which is convenient for adjusting the height position of the supporting wheel 42, thereby facilitating the adjustment of the distance between the supporting wheel 42 and the axis of the quartz tube.

[0068] The working principle of the present invention is as follows: the rotating roller 33 and the supporting wheel 42 limit the quartz tube from the inner and outer sides of the quartz tube respectively, so as to improve the uniformity of the diameter of the inner wall of the quartz tube. By adjusting the distance between the rotating roller 33 and the supporting wheel 42 and the axis of the quartz tube, it can adapt to quartz tubes of different diameters. Compared with the fixed-size sleeve set on the outside of the quartz tube in the prior art, the applicability is improved, and the sliding arm 31 and the shaft body 32 are detachably connected, so that in the process of moving the shaft body 32 and the rotating roller 33 from one end of the quartz tube to the other end, the shaft body 32 moves from one sliding arm 31 to the other sliding arm 31. Compared with the prior art, it avoids the need to extend the rotating roller 33 into the inner side of the quartz tube from both ends twice to expand the two ends of the quartz tube respectively, thereby improving the convenience of quartz tube expansion.

[0069] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
