Description

TECHNICAL FIELD

[0001] The utility model relates to glass substrate manufacturing technical field especially relates to a centering device. BACKGROUND

[0002] In the manufacturing process of glass substrate, the glass liquid melted by the tank furnace needs to enter the platinum channel to be clarified and homogenized, so as to obtain high-quality glass liquid meeting the forming requirements. In use, the platinum channel stirring rod is installed on the channel stirring mechanism, and the channel stirring mechanism drives the platinum stirring rod to rotate in the platinum channel stirring barrel at the required speed and direction, so as to stir the glass liquid in the platinum channel stirring barrel, thereby reducing the glass stripes, uniforming the glass liquid material, and improving the quality of glass products.

[0003] In order to ensure the stirring effect of the platinum stirring rod on the glass liquid in the platinum channel stirring barrel, after the stirring rod is put into the stirring barrel, it needs to be measured multiple times to confirm the centering of the stirring rod and the center of the stirring barrel. In the prior art, the confirmation method of whether the stirring rod and the center of the stirring barrel are centered is usually as follows: in the top plane of the stirring barrel, the distance between the outer contour of the stirring rod and the inner wall of the stirring barrel is measured by using a steel ruler, and when the distance between the outer contour of the stirring rod and the inner wall of the stirring barrel measured by the operator in the horizontal plane along two mutually perpendicular directions is equal, it indicates that the stirring rod and the center of the stirring barrel have been centered.

[0004] However, the above measurement method has the following problems: 1) because the temperature of the on-site stirring barrel is high, the steel ruler is easy to be loosened by the operator due to the hot hand, and then the steel ruler falls into the stirring barrel; 2) because the cross section of the stirring barrel is circular, it is difficult to accurately place the steel ruler when measuring, which causes reading error, and the consistency of the reading is poor when repeatedly measuring at the same position; 3) when the measurement error is large, it will seriously affect the centering accuracy of the stirring rod and the stirring barrel during actual installation, endanger the safety of equipment operation, and cause poor process operation effect; 5) during normal operation of the equipment, the stirring barrel is covered with a cover brick, so it is impossible to judge whether the stirring rod is centered.

[0005] Therefore, it is urgent to provide a centering device to solve the above problems. UTILITY MODEL CONTENTS

By arranging the heat preservation assembly 40, the stirring barrel 20 can be heat preserved, so as to prevent excessive heat loss of the stirring barrel 20 and affect the quality of the glass liquid.

[0045] The platinum channel equipment needs to ensure the centering of the stirring rod 10 and the stirring barrel 20 in operation, so as to ensure the stirring effect of the stirring rod 10 on the glass liquid in the stirring barrel 20. In order to accurately detect the centering of the stirring rod 10 and the stirring barrel 20, the embodiment provides a centering device which is simple in structure, convenient to operate and high in detection accuracy. The specific structure and detection principle of the centering device provided by the embodiment will be described in detail below. Figures 3-8 The specific structure and detection principle of the centering device provided by the embodiment will be described in detail below.

Figure 4 The structure schematic diagram of the centering device provided by the embodiment is shown from another perspective. Figure 5 The cross-sectional structure schematic diagram of the centering device provided by the embodiment is shown. As shown in Figures 3-5 The specific structure and detection principle of the centering device provided by the embodiment will be described in detail below. Figure 1 , Figure 2 The centering device provided by the embodiment includes a mounting shell 100, a clamping assembly 200 and a detection assembly 300, wherein the mounting shell 100 is a shell-shaped structure with open ends; the clamping assembly 200 is arranged on the mounting shell 100 and can clamp the stirring rod 10; the detection assembly 300 includes a gear 310, a rack 320 and a detection piece 330; the gear 310 is rotatably arranged in the mounting shell 100; two racks 320 are located on both sides of the gear 310 and are in meshing connection with the gear 310; each rack 320 includes opposite first and second ends 321 and 322; each second end 322 is connected with a detection piece 330; when the gear 310 is rotated, the two racks 320 can be driven to move, so that the corresponding detection pieces 330 are extended or retracted from the end opening of the mounting shell 100; when the two detection pieces 330 simultaneously abut against the inner wall of the stirring barrel 20 or the outer wall of the base 30, the stirring rod 10 is centered with the stirring barrel 20.

[0047] The centering device provided by the embodiment can mount the clamping assembly 200 and the detection assembly 300 through the mounting shell 100, and the mounting shell 100 can accommodate the gear 310 and the rack 320, thereby protecting the gear 310 and the rack 320 from being damaged by external dust or high temperature. During detection, the operator only needs to rotate the gear 310 to drive the detection pieces 330 to extend out of the end opening of the mounting shell 100 through the rack 320, and when the two detection pieces 330 can simultaneously abut against the inner wall of the stirring barrel 20 or the outer wall of the base 30, it can be judged that the stirring rod 10 and the stirring barrel 20 are centered. The operation is convenient and fast, and the error caused by inaccurate reading during detection in the prior art can be overcome, the detection precision is high, and the centering installation precision of the stirring rod 10 and the stirring barrel 20 can be ensured to ensure the process effect of the stirring rod 10. In addition, since the stirring barrel 20 is coaxially mounted on the base 30, when the platinum channel equipment is running, the centering device can judge whether the stirring rod 10 and the stirring barrel 20 are centered by judging whether the two detection pieces 330 can simultaneously abut against the outer wall of the base 30, without the need to remove the heat preservation assembly 40 on the stirring barrel 20, thereby maintaining the stability of the process environment and ensuring the continuity of production.

[0048] Optionally, the mounting shell 100 is made of stainless steel, which has high structural strength and is resistant to high temperature.

[0049] For the convenience of understanding, the following will first combine the centering device with the platinum channel equipment. Figure 6 Briefly describe the use method of the centering device.

[0050] Figure 6 The structure schematic diagram of the centering device provided by the embodiment is shown when the platinum channel equipment is installed and detected. As shown in Figure 6 and combined with Figure 4 , Figure 5As shown, before the platinum channel device is operated, the method for using the centering device is as follows: 1) after the stirring rod 10 is placed in the stirring barrel 20, the operator can first hold the mounting shell 100 and make the clamping assembly 200 clamp the stirring rod 10; 2) rotate the gear 310 to drive the detection pieces 330 to extend from the end openings of the corresponding side of the mounting shell 100 through the rack 320 until the detection pieces 330 abut against the inner wall of the stirring barrel 20, at this time, the operator can observe whether the other detection piece 330 also abuts against the inner wall of the stirring barrel 20; 3) if the two detection pieces 330 simultaneously abut against the inner wall of the stirring barrel 20, the detection pieces 330 are retracted and the stirring rod 10 is rotated to 90°, and the above steps are repeated, if the two detection pieces 330 simultaneously abut against the inner wall of the stirring barrel 20, it is judged that the stirring rod 10 is centered with the stirring barrel 20, at this time, the centering device can be removed from the stirring rod 10, and after the heat preservation assembly 40 is installed on the stirring barrel 20, the stirring mechanism can be started to drive the stirring rod 10 to stir the glass liquid in the stirring barrel 20; 4) if only one of the two detection pieces 330 abuts against the inner wall of the stirring barrel 20, and the other detection piece 330 does not abut against the inner wall of the stirring barrel 20, at this time, the operator needs to adjust the position of the stirring rod 10, and after adjustment, the above steps 1) to 2) are repeated until the two detection pieces 330 can simultaneously abut against the inner wall of the stirring barrel 20, and then the centering device is removed.

[0051] Optionally, each detection piece 330 comprises a mounting portion 331 and an abutting portion 332 connected to the mounting portion 331, and the abutting portion 332 is connected to the corresponding second end 322 through the mounting portion 331. By arranging the abutting portion 332, when operating, the gear 310 can be rotated to make the abutting portion 332 abut against the inner wall of the stirring barrel 20, at this time, the clamping assembly 200 can be clamped at the position close to the top end of the stirring rod 10, avoiding the operator being scalded due to being too close to the high-temperature barrel body when operating, thereby ensuring the safety of the operator. Of course, in other embodiments, the abutting portion 332 can not be arranged, and the end of the mounting portion 331 away from the rack 320 can directly abut against the inner wall of the stirring barrel 20, which also can achieve the above effect.

[0052] Figure 7 Fig. 4 shows a structural schematic diagram of the centering device provided by the embodiment when detecting in the operation of the platinum channel device. As shown in Fig. 4, the centering device is arranged in the stirring barrel 20, and the stirring rod 10 is arranged in the centering device. Figure 7 and combined with Figure 4 , Figure 5As shown, the method for using the centering device during the operation of the platinum channel equipment is as follows: 1) the operator first rotates the gear 310 to drive the detection pieces 330 to extend out of the end opening of the corresponding side of the installation shell 100 through the rack 320, then holds the installation shell 100 by hand and makes the clamping assembly 200 clamp the stirring rod 10, and at this time, the two detection pieces 330 are located outside the heat preservation assembly 40 respectively; 2) rotate the gear 310 to drive the detection pieces 330 to retract into the installation shell 100 through the rack 320, and stop rotating the gear 310 when the detection pieces 330 abut against the outer wall of the base 30, at this time, the operator can observe whether the other detection piece 330 also abuts against the outer wall of the base 30; 3) if the two detection pieces 330 abut against the outer wall of the base 30 at the same time, it is judged that the stirring rod 10 is centered with the stirring barrel 20, at this time, the centering device can be removed from the stirring rod 10 to continue the operation of the platinum channel equipment; 4) if only one of the two detection pieces 330 abuts against the outer wall of the base 30, and the other detection piece 330 does not abut against the outer wall of the base 30, at this time, the operator needs to adjust the position of the stirring rod 10, and after adjustment, repeat the above steps 1)~2), and then remove the centering device after the two detection pieces 330 abut against the outer wall of the base 30 at the same time. The detection method can detect the centering condition of the stirring rod 10 of the platinum channel equipment in operation, without the need to remove the heat preservation assembly 40 on the stirring barrel 20, so as to maintain the stability of the process environment and ensure the continuity of production.

[0053] In order to improve the universality of the centering device, as shown in Figures 3-7 The number of abutting portions 332 in each detection piece 330 is multiple, the heights of the multiple abutting portions 332 are different, and the multiple abutting portions 332 are selectively detachably connected to the corresponding installation portion 331. By adopting this arrangement, when the operator uses different detection methods to detect the centering condition of the stirring rod 10, the abutting portions 332 with different heights can be selected to further improve the operation convenience of the centering device. For example, when the operator uses the detection method as shown in Figure 6 The abutting portions 332 with lower heights are selected to be connected to the installation portion 331, so that the abutting portions 332 can abut against the inner wall of the stirring barrel 20, and the abutting portions 332 can avoid being too long to extend below the liquid level of the glass liquid in the stirring barrel 20 to pollute the glass liquid; when the operator uses the detection method as shown in Figure 7 The abutting portions 332 with higher heights are selected to be connected to the installation portion 331, so that the abutting portions 332 can abut against the outer wall of the base 30, and the clamping assembly 200 can clamp the upper end of the stirring rod 10.

[0054] In the embodiment, the abutting portion 332 is a screw threadedly connected to the corresponding mounting portion 331, which is simple in structure, convenient to disassemble and assemble, and can reduce manufacturing cost.

[0055] Optionally, the mounting portion 331 is provided with a sliding groove 3311, and the inner wall of the mounting shell 100 is provided with a sliding protrusion in sliding cooperation with the sliding groove 3311. By respectively providing the sliding groove 3311 and the sliding protrusion in sliding cooperation on the mounting portion 331 and the mounting shell 100, the movement of the mounting portion 331 relative to the mounting shell 100 can be guided to limit the degree of freedom of the mounting portion 331, thereby ensuring the centering accuracy of the centering device.

[0056] As shown in Figures 3-5 To realize the rotation of the gear 310, the detection assembly 300 further includes a hand wheel 340 and a connecting rod (not shown in the figure), one end of the connecting rod is connected to the hand wheel 340, and the other end of the connecting rod extends into the mounting shell 100 and is connected to the gear 310. The operator can manually rotate the hand wheel 340 to drive the gear 310 to rotate through the connecting rod, thereby realizing the extension or retraction of the detection piece 330 through the rack 320, which is simple in structure and convenient to operate.

[0057] Optionally, the length of the connecting rod is greater than the radius of the stirring barrel 20. This setting can make the hand wheel 340 be outside the upper opening coverage area of the stirring barrel 20, so as to avoid the operator from being scalded by the steam of high-temperature glass liquid when rotating the hand wheel 340, thereby further ensuring the safety of the operator.

[0058] To avoid the rack 320 from being detached from the rack 320 when moving relative to the gear 310, in the embodiment, the first end 321 of each rack 320 is provided with a limiting structure 3211, and when the limiting structure 3211 abuts against the gear 310, the length of the rack 320 extending out of the mounting shell 100 is maximum. Optionally, the limiting structure 3211 is a protruding structure protruding from the first end 321 of the rack 320, and when the protruding structure abuts against the gear 310, the gear 310 cannot continue to rotate in the same direction, thereby realizing the limiting action on the rack 320.

[0059] Optionally, the gear 310, the rack 320, the mounting portion 331 and the hand wheel 340 are all made of stainless steel, which has high structural strength and is resistant to high temperature.

[0060] Figure 8 Fig. 6 shows a structural schematic diagram of the centering device provided by the embodiment in another view. As shown in Figure 8 and in combination with Figures 3-6As shown, the clamping assembly 200 includes a fixed clamping member 210 and a movable clamping member 220. The fixed clamping member 210 is fixedly arranged on the mounting shell 100; the movable clamping member 220 can be movably arranged on the mounting shell 100 along the radial direction of the mixing barrel 20, and the fixed clamping member 210 and the movable clamping member 220 can be closed to clamp the stirring rod 10.

[0061] Furthermore, the sides of the fixed clamping member 210 and the movable clamping member 220 facing each other are both arc-shaped surfaces. When the two are closed to clamp the stirring rod 10, the arc-shaped surfaces fit into the side surfaces of the cylindrical stirring rod 10, thereby increasing the contact area between the fixed clamping member 210 and the stirring rod 10 and between the movable clamping member 220 and the stirring rod 10, thereby improving the stability of the clamping assembly 200 in clamping the stirring rod 10.

[0062] To prevent the movable clamping member 220 from changing position relative to the mounting housing 100 during detection, the clamping assembly 200 further includes a locking member 230 that can lock the relative position between the movable clamping member 220 and the mounting housing 100. Optionally, in this embodiment, the locking member 230 is a jackscrew, which has a simple structure, good locking effect, and is easy to operate. Of course, in other embodiments, the locking member 230 can also be a locking bolt that passes through the movable clamping member 220 and is threadedly connected to the mounting housing 100, thereby achieving the above-mentioned effect.

[0063] Alternatively, as Figure 3 As shown, there are two locking members 230, which are respectively located on the upper and lower sides of the mounting shell 100. The two locking members 230 simultaneously lock the movable clamping member 220, further ensuring that the movable clamping member 220 will not shift relative to the mounting shell 100 when the centering device is in use.

[0064] To adjust the position of the movable clamping member 220 on the mounting shell 100, a T-shaped slot is provided on the mounting shell 100, and a T-shaped protrusion is provided on the movable clamping member 220. The T-shaped protrusion slides in the T-shaped slot. The operator can manually push the movable clamping member 220 to slide relative to the mounting shell 100 in the radial direction of the mixing barrel 20, thereby approaching or moving away from the fixed clamping member 210 to clamp or release the stirring rod 10. Optionally, the fixed clamping member 210 is welded to the mounting shell 100, thereby achieving fixed installation of the fixed clamping member 210 on the mounting shell 100, facilitating processing and providing a secure connection.

[0065] Optionally, the fixed clamping member 210 , the movable clamping member 220 and the locking member 230 are all made of stainless steel, which has high structural strength and is resistant to high temperatures.

[0066] It should be noted that, after the centering device is assembled, the center axes of the threaded holes on the two mounting portions 331 for connecting the abutting portions 332 and the centers of the arc surfaces of the fixed clamping member 210 and the arc surfaces of the movable clamping member 220 are in the same straight line, so that, when the centering device detects the centering of the stirring rod 10 and the stirring barrel 20, and the two abutting portions 332 simultaneously abut against the inner wall of the stirring barrel 20, the line between the positions where the abutting portions 332 abut against the inner wall of the stirring barrel 20 passes through the axis of the stirring barrel 20, thereby further improving the centering accuracy of the centering device.

[0067] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Without departing from the spirit and scope of the present application, various changes and modifications can be made to the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
