Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz crystal processing technology, and in particular to a quartz tube positioning and cutting device. Background Technology
[0002] Quartz tubes are a type of special industrial glass tube primarily made of silicon dioxide with a purity of 99.9% or higher. They possess properties such as high temperature resistance (melting point approximately 1713℃, capable of prolonged operation at around 1100℃), good thermal stability (extremely low coefficient of thermal expansion), high light transmittance (good light transmittance in the ultraviolet to infrared bands), high electrical insulation, and good chemical stability (resistant to most acids and alkalis). Production typically involves melting quartz stone in a continuous melting furnace, drawing it into shape, and then cutting the quartz tubes to the required length after they exit the furnace.
[0003] The cutting device vertically fixes the quartz tube using a vertical fixed support rod on the fixed base and a flexible limiting plug at the top, accommodating quartz tubes of various lengths. A horizontally positioned cutting assembly is located in the middle of the telescopic shaft of the first vertical cylinder, connected to a connecting block. A transverse cylinder is located between the blade holder in the cutting assembly and the connecting block to adjust the cutting position. The blade holder houses a cutting blade driven by a first rotary motor. The first vertical cylinder drives the cutting blade downwards, while the transverse cylinder adjusts the cutting position. Simultaneously, a second rotary motor rotates the quartz tube at a uniform speed, causing the cutting blade to perform a circumferential cut on the quartz tube. The cutting surface is small, and the force is evenly distributed.
[0004] In the prior art, some cutting devices are fixed by a vertical fixed support rod and a flexible limiting plug at the top during processing. However, during the cutting process, the cutting head will generate an impact force on the quartz tube, causing it to shake, which will affect the cutting accuracy. Therefore, a quartz tube positioning and cutting device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a quartz tube positioning and cutting device, which aims to improve the problem in the prior art where the cutting head will exert an impact force on the quartz tube during the cutting process, causing it to shake and affecting the cutting accuracy.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A quartz tube positioning and cutting device includes an operating table. A placement box is fixedly connected inside the operating table.

The fixing ring has multiple cavities inside, and a spring is fixedly connected to the inner wall of each cavity. A limit plate is fixedly connected to the other end of the spring, and an extension column is fixedly connected to the other side of the limit plate. A frosted plate is fixedly connected to the other side of the multiple extension columns.

Polishing before cutting facilitates processing, and polishing after cutting ensures the smoothness of the cut part of the quartz tube, improving the aesthetics of the production.

[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 Figures 1 to 2 This utility model provides an embodiment of a quartz tube positioning and cutting device, including an operating table 1. The operating table 1 is the basic structure of the entire quartz tube positioning and cutting device, used to support other components. A placement box 2 is fixedly connected inside the operating table 1, and a motor 3 is fixedly connected inside the placement box 2. The placement box 2 provides a stable placement space for the motor 3. When the motor 3 is running, the placement box 2 can withstand the vibration and other forces generated by the motor 3, preventing the motor 3 from shifting or shaking during operation, thereby ensuring the stability and reliability of the entire device.
[0033] Motor 3 is the power source of the device. A fixed column 4 is fixedly connected to the drive end of motor 3, and a turntable 5 is fixedly connected to the outside of the fixed column 4, transmitting the rotational motion of motor 3 to the turntable 5. Two connecting rods 6 are rotatably connected to the outside of the turntable 5, rotating under the drive of motor 3. The rotation of the two connecting rods 6 drives the movement of the connecting rods 6. A connecting rod 7 is rotatably connected to the other end of the connecting rod 6. Two square grooves 9 are provided on the top of the operating platform 1 to limit the sliding trajectory of the connecting rod 7.
[0034] The connecting rod 7 is externally slidably connected to the inner wall of the square slide groove 9. When the turntable 5 rotates, the connecting rod 6 will also perform circular motion, and through its rotational connection with the connecting rod 7, the rotational motion of the turntable 5 is converted into the sliding motion of the connecting rod 7 on the inner wall of the square slide groove 9. A clamping plate 8 is fixedly connected to the top of the connecting rod 7. Under the rotation of the connecting rod 6, the connecting rod 7 slides in the square slide groove 9, thereby driving the clamping plate 8 to move closer or further apart.
[0035] The clamping plate 8 clamps and fixes the quartz tube under the action of the connecting rod 7. The operating table 1 is equipped with a limit component, which can limit the movement trajectory of the clamping plate 8. The limit component includes a rotating groove, which is opened inside the placement box 2. The connecting rod 6 is externally rotatably connected to the inner wall of the rotating groove.
[0036] Reference Figures 3 to 4The top left and right sides of the operating table 1 are fixedly connected to lower clamping plates 10, and the top of the lower clamping plates 10 is detachably connected to an upper clamping plate 11, which cooperates with the upper clamping plate 11 to fix the quartz tube. The lower clamping plate 10 is equipped with an adjustment component to accommodate quartz tubes of different sizes. The position and installation method of the lower clamping plate 10 must ensure that it remains stable during the operation of the device and can accurately cooperate with the upper clamping plate 11 to fix the quartz tube.
[0037] The lower clamping plate 10 is equipped with an adjustment assembly that can accommodate quartz tubes of different sizes. The adjustment assembly includes a fixing ring 12, which is fixedly connected to the top of the lower clamping plate 10. The fixing ring 12 serves to support and accommodate other related components. The fixing ring 12 has multiple cavities 13 inside. A spring 14 is fixedly connected to the inner wall of the cavity 13. The other end of the spring 14 is fixedly connected to a limiting plate 15. The limiting plate 15 is slidably connected to the inner wall of the cavity 13. The cavity 13 ensures that the spring 14 can extend and retract stably within it, and the limiting plate 15 can slide smoothly on its inner wall, thus ensuring the normal operation of the entire adjustment assembly.
[0038] An extension post 16 is fixedly connected to the other side of the limiting plate 15. The limiting plate 15 plays a role in transmitting force in the entire adjustment assembly, transferring the elastic force of the spring 14 to the extension post 16, and ensuring the stability and directionality of the movement through sliding on the inner wall of the cavity 13. The extension post 16 is externally slidably connected to the inner wall of the cavity 13. When the quartz tube is inserted, the extension post 16 transfers the external force on the frosting plate 17 to the limiting plate 15, thereby compressing the spring 14. A frosting plate 17 is fixedly connected to the other side of the multiple extension posts 16. While being compressed, the spring 14 generates a reaction force on the limiting plate 15, making the frosting plate 17 fit more tightly with the quartz tube. When the quartz tube is inserted, the frosting plate 17 adjusts its position according to the size of the quartz tube and fits tightly with the quartz tube under the action of the spring 14. When polishing the quartz tube, rotating the quartz tube allows the frosting plate 17 to polish its surface, making it smooth.
[0039] Two limiting posts 18 are slidably connected inside both the upper clamping plate 11 and the lower clamping plate 10. A second spring 19 is sleeved on the outside of each limiting post 18. One end of the second spring 19 is fixedly connected to the outside of the limiting post 18. The limiting post 18 serves to limit and guide the second spring 19. During the quartz tube fixing process, the limiting post 18 works in conjunction with the second spring 19 to adjust the position of the upper clamping plate 11 according to the size of the quartz tube, further fixing the quartz tube. The other end of the second spring 19 is fixedly connected to the outside of the upper clamping plate 11. When the quartz tube is placed between the lower clamping plate 10 and the upper clamping plate 11, the upper clamping plate 11 will press the second spring 19 upwards. The second spring 19 is compressed against the outside of the limiting post 18, and the elasticity of the limiting post 18 further fixes the quartz tube.
[0040] The outer side of the abrasive plate 17 contacts the side of the fixing ring 12 near the extension column 16. The interior of the lower clamping plate 10 and the interior of the upper clamping plate 11 are both threaded with fixing bolts 20. After the quartz tube is placed and initially fixed using adjusting components and springs, the fixing bolts 20 are used to tighten the lower clamping plate 10 and the upper clamping plate 11, ensuring that the quartz tube will not shift during grinding, cutting, or other operations. Support frames 21 are slidably connected to the front and rear sides of the operating table 1. A cutting head 22 is slidably connected to the outside of the support frames 21. The support frames 21 provide support and position adjustment for the cutting head 22, which is used to cut the quartz tube.
[0041] Working principle: First, place the operating table 1 in a suitable position, then place the quartz tube inside the frosted plate 17 on the left. According to the size of the quartz tube, the frosted plate 17 is forced outward to press the extension column 16. The extension column 16 pushes the limiting plate 15 to compress the spring 14, making it compressed inside the cavity 13. While being compressed, the spring 14 generates a reaction force on the limiting plate 15, making the frosted plate 17 fit more tightly with the quartz tube. At the same time, the lower clamping plate 10 and the upper clamping plate 11 are also forced outward. At this time, the upper clamping plate 11 will press the spring 2 19 upward. The spring 2 19 is compressed outside the limiting column 18. The elasticity of the limiting column 18 can be used to further fix the quartz tube. Then, the lower clamping plate 10 and the upper clamping plate 11 are fixed with the fixing bolt 20. Rotating the quartz tube can use the frosted plate 17 to polish its surface and make it smooth.
[0042] Then, the quartz tube is pushed to the right, and then the motor 3 is started. Under the drive of the motor 3, the fixed column 4 rotates, thereby realizing the rotation of the turntable 5. The rotation of the turntable 5 enables the two connecting rods 6 to rotate. When the connecting rods 6 rotate, they will pull the connecting rod 7 to slide on the inner wall of the square slide groove 9, thereby realizing the clamping plate 8 to move in a similar direction and clamp and fix the quartz tube. Then, the position of the support frame 21 on the operating table 1 is adjusted, and the cutting head 22 is started to cut the quartz tube. After the cutting is completed, it continues to move to the right and enters the interior of the right-side frosting plate 17. At this time, the frosting plate 17 polishes the cut quartz tube to make the cut more smooth.
[0043] 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.
