[0023] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] A real-time online detection device for the wall thickness of borosilicate glass tubes includes a fixed frame 1, a mounting plate 2 on the top of the fixed frame 1, a gear 7 connected to a motor 6 on the mounting plate 2, a gear disc 4 meshing with the gear 7 movably mounted on the mounting plate 2, and a detector 5 on the gear disc 4; a through hole is opened in the center of the gear disc 4, and an opening that mates with the through hole is provided on the mounting plate 2; multiple fixed tubes 11 are provided on the mounting plate 2, each fixed tube 11 is provided with a telescopic rod 12, and a clamping block 9 is provided at the end of each telescopic rod 12 away from the fixed tube 11, the clamping block 9 being located between the through hole and the opening; an air pump 14 is also provided on the mounting plate 2, and an air pipe 13 connected to the air pump 14 is provided on each fixed tube 11; the borosilicate glass tube to be detected passes through the through hole and the opening, and the telescopic rod 12 is driven by the air pump 14 to telescopically move within the fixed tube 11, and the clamping block 9 moves closer to or away from the opening as the telescopic rod 12 moves.

[0025] Furthermore, the mounting plate 2 is also provided with positioning rings 8 in the same number as the clamping blocks 9. Each clamping block 9 is provided with a guide post, which passes through the positioning ring 8, so that the guide post is movably mounted on the positioning ring 8.

[0026] Furthermore, a spring 10 is also provided on the guide column. One end of the spring 10 is connected to the clamping block 9, and the other end of the spring 10 is connected to the positioning ring 8.

[0027] Furthermore, each clamping block 9 has a rubber pad 15 on the side facing away from the telescopic rod 12.

[0028] Furthermore, the mounting plate 2 is provided with a protective shell 16 for protecting the gear disc 4, and the gear disc 4 is located inside the protective shell 16.

[0029] Furthermore, a guide ring 3 is provided on the mounting plate 2, and an annular protrusion is provided on the gear disk 4. The annular protrusion is embedded in the guide ring 3, and the gear disk 4 rotates on the guide ring 3 as driven by the motor 6.

[0030] Furthermore, detector 5 is a laser probe, with the emitting end of the laser probe facing the center of the toothed disk 4. The laser probe can emit laser light towards the borosilicate glass tube to be tested and receive the laser light reflected back from the borosilicate glass tube to be tested. The laser probe and the controller are connected by communication.

[0031] Furthermore, the bottom of the mounting bracket 1 is provided with a base for providing support.

[0032] In a specific embodiment, such as Figures 1 to 4 As shown, the borosilicate glass tube wall thickness online real-time detection device proposed in this application consists mainly of a load-bearing fixed frame 1. At the bottom of the fixed frame 1, a wide plate-shaped base is provided, which increases the contact area between the fixed frame 1 and the ground, thus providing support. This design enhances the stability of the fixed frame 1 and all components mounted on it, maintaining its original posture and preventing swaying and tilting, whether facing minor vibrations during daily operation or more severe external disturbances.

[0033] A mounting plate 2 is installed on the top of the mounting frame 1, and a geared disc 4 is mounted on the mounting plate 2 in a movable manner. Specifically, a guide ring 3 is provided on the mounting plate 2 to enable the rotation of the geared disc 4. An annular protrusion is provided on the side of the geared disc 4 closest to the mounting plate 2, and the shape of the annular protrusion matches that of the guide ring 3, allowing the annular protrusion to be embedded within the guide ring 3. A gear 7 connected to a motor 6 is also provided on the mounting plate 2, and this gear 7 meshes with the geared disc 4. When the motor 6 drives the gear 7 to rotate, the gear 4 rotates under the guidance of the guide ring 3 because the gear 7 meshes with the teeth on the geared disc 4.

[0034] In addition, a protective shell 16 is provided on the mounting plate 2, which surrounds the teeth of the gear disc 4. This is designed to prevent external factors from interfering with or damaging the teeth on the gear disc 4. The protective shell 16 can prevent dust, debris, etc., from entering the interior of the gear disc 4, preventing these impurities from affecting its rotation. At the same time, the protective shell 16 can also prevent the teeth from colliding or rubbing against other objects during the rotation of the gear disc 4, thus preventing damage. This design ensures smooth and stable rotation of the gear disc 4, thereby improving overall reliability.

[0035] Here, a through hole is made at the center of the gear disc 4 to allow the borosilicate glass tube to be tested to pass through. Simultaneously, an opening is provided on the mounting plate 2 at a position corresponding to the through hole, ensuring that the borosilicate glass tube can smoothly pass through the mounting plate 2 and the gear disc 4. To more securely clamp the glass tube, three fixing tubes 11 are provided around the opening in the mounting plate 2. Each of these fixing tubes 11 is equipped with a telescopic rod 12, which can extend and retract within the fixing tube 11. A clamping block 9 is installed at the end of each telescopic rod 12 furthest from the fixing tube 11. The clamping block 9 moves closer to or further away from the opening as the telescopic rod 12 moves, thereby clamping and releasing the borosilicate glass tube to be tested. Furthermore, the clamping block 9 is located between the through hole and the opening, ensuring that the borosilicate glass tube to be tested is stably clamped on the mounting plate 2 and the gear disc 4.

[0036] To achieve the automatic clamping and releasing function of the clamping blocks 9, an air pump 14 is installed on the mounting plate 2. This air pump 14 is connected to three fixed pipes 11 via three air pipes 13. In addition, the mounting plate 2 is equipped with positioning rings 8, the same number as the clamping blocks 9. Each clamping block 9 has a guide post, which passes through the positioning ring 8, allowing the guide post to be movably mounted on the positioning ring 8. This enables the clamping block 9 to move under the guidance of the guide post, preventing it from tilting during movement. Furthermore, a spring 10 is installed on each guide post. One end of this spring 10 is connected to the clamping block 9, and the other end is connected to the positioning ring 8. This not only provides additional power support for the movement of the clamping blocks 9 but also ensures the stability and reliability of the clamping blocks 9 during movement.

[0037] In practical use, after the borosilicate glass tube to be tested passes through the through hole of the toothed disc 4 and the opening of the mounting plate 2, the movement of the clamping block 9 can be controlled by the air pump 14. Specifically, when the air pump 14 starts to evacuate the vent pipe 13, the telescopic rod 12 in the fixed tube 11 connected to the vent pipe 13 is pulled inward by suction, causing the clamping block 9 to move away from the opening. At this time, the guide post moves towards the fixed tube 11 on the positioning ring 8, compressing the spring 10. This process causes the clamping block 9 to release its grip on the borosilicate glass tube to be tested, making it easier to remove the borosilicate glass tube. When the air pump 14 stops evacuating the vent pipe 13, the rebound force of the spring 10 begins to take effect. The rebound of the spring 10 pushes the guide post towards the opening, thereby causing the telescopic rod 12 in the fixed tube 11 to extend outward. This movement causes the clamping block 9 to move toward the opening, thereby clamping the borosilicate glass tube to be tested.

[0038] In addition, a rubber pad 15 is provided on the contact surface between the clamping block 9 and the borosilicate glass tube to be tested. This rubber pad 15 can play a protective and shock-absorbing role, preventing the borosilicate glass tube to be tested from being damaged during clamping. At the same time, the excellent friction properties of the rubber pad 15 can also improve the stability of clamping.

[0039] Specifically, detector 5 is a laser probe, with its emitting end facing the center of the gear disk 4. The laser probe emits laser light towards the borosilicate glass tube to be tested and receives the laser light reflected back from the tube. The laser probe is connected to the controller via a communication link. Since detector 5 is mounted on the gear disk 4, it rotates with the disk 4. This design allows detector 5 to rotate around the borosilicate glass tube. During the testing process, the laser probe continuously emits laser light and receives reflected light. This reflected light carries information about the borosilicate glass tube, which is then transmitted to the processor in the controller for further calculations and digital signal conversion. Based on this information, the wall thickness of the borosilicate glass tube is calculated, thus achieving real-time detection of the tube's wall thickness.

[0040] In summary, through these designs, the online real-time wall thickness detection device for borosilicate glass tubes proposed in this application can automatically clamp and detect the wall thickness of borosilicate glass tubes of different sizes. Whether it's a small-diameter thin tube or a large-diameter thick tube, it can be securely and automatically clamped. This feature not only improves the versatility of this application but also reduces the time spent manually adjusting the clamping of the borosilicate glass tube, thus improving work efficiency.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
