Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass tube cutting technology, and in particular to a high borosilicate glass tube cutting device. Background Technology
[0002] High borosilicate glass tubes are widely used in optical instruments, medical equipment, and semiconductor manufacturing due to their high temperature resistance, corrosion resistance, and low coefficient of expansion. However, their high hardness and brittleness make cutting difficult, and traditional cutting methods easily cause the glass tubes to crack or the cut edges to chip, seriously affecting the yield and processing efficiency. With the increasing demand for precision manufacturing, developing an automated cutting device that can ensure cutting accuracy and adapt to glass tubes of various specifications has become a pressing technical challenge for the industry.
[0003] Currently, the cutting of high borosilicate glass tubes mainly relies on technologies such as mechanical blade circumferential cutting, internal thermal fracture, or laser cutting. Mechanical cutting devices apply mechanical stress to the surface of the glass tube by rotating blades to achieve fracture. Their structure typically includes a power transmission mechanism, a fixing fixture, and a cutting head. Internal thermal fracture devices use heating elements to soften the glass locally and then apply pressure to fracture it. Laser cutting achieves high-precision cutting by focusing a beam to vaporize the glass.
[0004] However, the blade spacing of traditional borosilicate glass tube cutting devices is usually fixed. When cutting glass tubes of different diameters, it is necessary to manually change special fixtures or recalibrate the blade position. This process is not only time-consuming and labor-intensive, but also prone to cutting position deviation or unstable glass tube clamping due to insufficient compatibility between the blade and the glass tube, which can lead to chipping or even cracking of the cut. Especially in the cutting of thin-walled glass tubes, the fixed blade spacing cannot dynamically compensate for the difference in tube diameter, further reducing the cutting accuracy and yield. This has become a core technical bottleneck restricting the efficient processing of multi-specification glass tubes. To address this issue, a borosilicate glass tube cutting device is proposed.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a high borosilicate glass tube cutting device, which includes an operating table 1. An adjustment component is provided on the top of the operating table 1. The adjustment component is used to facilitate the user to adjust the spacing between the cutting blades.
[0033] The adjustment assembly includes a fixed rod 2, which is fixedly connected to the top of the operating table 1 to ensure its stability and durability. A cutting head 3 is slidably connected inside the fixed rod 2 for cutting the glass tube. A fixed block 4 is fixedly connected to one side of the fixed rod 2 to provide stable support and connection for the assembly. A sliding rod 5 is slidably connected inside the fixed block 4. A pull plate 6 is fixedly connected to one end of the sliding rod 5 to facilitate the user's movement of the assembly for quick adjustment. A locking block 7 is fixedly connected to the other end of the sliding rod 5. Both the fixed rod 2 and the cutting head 3 have slots 8 inside. The locking block 7 fits into the slots 8 to achieve quick locking and unlocking. A spring 9 is provided on the outer wall of the sliding rod 5 to provide elastic restoring force, ensuring the stability of the assembly's movement and ensuring that the assembly can quickly reset. One end of the spring 9 is fixedly connected to the inner wall of the fixed block 4, and the other end is fixedly connected to one side of the locking block 7. A limit assembly is provided on one side of the operating table 1 to limit the movement of the glass tube.
[0034] Specifically, when cutting high borosilicate glass tubes of different diameters, and dynamically adapting to changes in tube diameter by adjusting the blade spacing to avoid frequent replacement or calibration of the blade head, the operator first applies a pulling force by pulling the pull plate 6, causing the sliding rod 5 to slide inside the fixed block 4. The movement of the sliding rod 5 further drives the locking block 7 to disengage from the locking slot 8, thereby unlocking. After unlocking, the operator can continue to pull the cutting blade head 3, causing it to slide in the fixed rod 2, thereby adjusting the spacing position of the cutting blade head 3. During this process, the movement of the locking block 7 also causes the spring 9 to undergo elastic deformation, providing sufficient restoring force to ensure that the entire assembly is stable and reliable during the adjustment process.
[0035] Reference Figure 3 The limiting component includes a support plate 10 and a slide rail 12. The support plate 10 is fixedly connected to one side of the operating table 1, and the slide rail 12 is fixedly connected to the top of the support plate 10 to provide a stable sliding trajectory for the slide plate 13 and ensure that the slide plate 13 can slide stably. A cylinder 11 is fixedly connected to the top of the support plate 10 for the movement of other components and to provide the necessary driving force for the component. The output end of the cylinder 11 is fixedly connected to the left and right symmetrical slide plates 13. Both slide plates 13 are slidably connected to the outer wall of the slide rail 12. A limiting block 17 is fixedly connected to the top of the support plate 10. A rack 14 is fixedly connected to one side of one of the slide plates 13. The rack 14 slides inside the limiting block 17 to ensure the stable movement of the rack 14.
[0036] Specifically, when cutting high borosilicate glass tubes, it is necessary to dynamically fix their position to prevent rolling or displacement, avoid cutting deviation, and ensure cutting accuracy and yield. The output end of cylinder 11 pushes slide plate 13 to slide on the outer wall of slide rail 12. The sliding of slide plate 13 drives rack 14 to slide synchronously inside limit block 17. The movement of rack 14 is then rotated through gear 15 meshing with it, thereby driving rack 2 16 to move synchronously.
[0037] Reference Figure 3 A gear 15 is rotatably connected to the top of the support plate 10 to transmit power and drive the synchronous movement of another slide plate 13. The gear 15 meshes with a rack 14. A rack 2 16 is fixedly connected to one side of the other slide plate 13, which also transmits power and drives the slide plate 13 to move synchronously in the opposite direction. The rack 2 16 meshes with the gear 15. A fixing rod 2 18 is fixedly connected to the top of the slide plate 13. A rubber plate 19 is fixedly connected to one side of the fixing rod 2 18 to contact the glass tube and limit the movement of the glass tube.
[0038] Specifically, the movement of rack 2 16 causes the two slide plates 13 to press in opposite directions simultaneously, pushing the rubber plate 19 to fit tightly against the glass tube. At this time, the rubber plate 19 undergoes elastic deformation, providing precise limiting and fixing for the glass tube, thereby ensuring stability and accuracy during the cutting process, and ensuring that the glass tube is properly limited and supported during the cutting process.
[0039] Working principle: When using this cutting device, the glass tube is cut by the cutting head 3. When it is necessary to adjust the spacing of the cutting head 3, the operator pulls the pull plate 6. Under the action of the pulling force, the sliding rod 5 slides inside the fixed block 4. The movement of the sliding rod 5 further drives the locking block 7 to disengage from the locking slot 8 to unlock. After unlocking, the cutting head 3 is pulled to slide inside the fixed rod 2, thereby adjusting the spacing of the cutting head 3. At the same time, the movement of the locking block 7 further compresses the spring 9, causing the spring 9 to undergo elastic deformation. The elastic deformation of the spring 9 provides a restoring force for subsequent components. When the glass tube needs to be limited and fixed during the cutting process, the output end of the cylinder 11 drives the slide plate 13 to slide on the outer wall of the slide rail 12. When the slide plate 13 slides, it drives the rack 14 to slide synchronously inside the limiting block 17. The movement of the rack 14 drives the gear 15 that meshes with it to rotate. When the gear 15 rotates, it drives the rack 16 to move synchronously, so that the two slide plates 13 press inward synchronously in opposite directions. The movement of the slide plates 13 drives the rubber plate 19, so that the rubber plate 19 fits against the glass tube, causing the rubber plate 19 to undergo elastic deformation, thereby limiting the glass tube.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
