Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a quartz glass laser cutting machine. Background Technology

[0002] Laser cutting machines utilize the high energy density of laser beams to cut and process materials. A laser beam generated by a laser generator is focused by an optical system to form a high-energy-density spot with an extremely small diameter (typically 0.1~0.5mm), which then irradiates the material surface. Quartz glass, on the other hand, is made by melting various pure natural quartz crystals. It has an extremely low coefficient of linear expansion and is mainly used in laboratory equipment and refining equipment for special high-purity products.

[0003] Common quartz glass products include quartz glass tubes. Current laser cutting technology for quartz glass tubes lacks a structure for positioning the tube; it is often simply placed on a support for cutting. This method leaves severe burn marks on the support after cutting. Furthermore, laser cutting is a thermal cutting process, melting a portion of the glass during the process. This molten portion can stick the support and glass together, and the position of the glass tube cannot be adjusted during the cutting process, resulting in poor flexibility. Therefore, we propose a quartz glass laser cutting machine to address these shortcomings. Summary of the Invention

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a quartz glass laser cutting machine that can effectively position the quartz glass tube during laser cutting, and can also rotate the quartz glass tube during the cutting process to cut other parts of the quartz glass tube, thereby improving the flexibility of the device and facilitating the operation of the user.

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.

[0026] like Figure 1-6 As shown, this utility model provides a technical solution: a quartz glass laser cutting machine, including a cutting table 1, a fixing plate 2 fixedly connected to the top of the cutting table 1, a hydraulic cylinder 3 fixedly installed on the outer side of the fixing plate 2, a housing 4 fixedly connected to the output shaft of the hydraulic cylinder 3, and limit rods 5 fixedly connected to both ends of the outer side of the housing 4. The outer side of the limit rods 5 is slidably connected to both sides of the hydraulic cylinder 3. A lifting assembly 6 is provided inside the housing 4, a positioning assembly 7 is provided at the top of the fixing plate 2, and a glass tube 8 is provided inside the positioning assembly 7. A horizontal moving platform 9 is fixedly connected to the outside of the horizontal moving platform 9. A support frame 10 is slidably connected to the top of the horizontal moving platform 9. A lead screw module 11 is fixedly installed on the outside of the support frame 10. A mounting plate 12 is slidably connected to the outside of the lead screw module 11. A sliding block 13 is slidably connected inside the mounting plate 12. A rotary motor 14 is fixedly connected to the top of the mounting plate 12. A screw 15 is fixedly connected to the output shaft of the rotary motor 14. The outside of the screw 15 is threadedly connected to the inner wall of the sliding block 13. A laser cutting head 16 is fixedly connected to the outside of the sliding block 13.

[0027] One end of the glass tube 8 is passed through the interior of the positioning component 7 and positioned on top of the lifting component 6. The positioning component 7 clamps and fixes one end of the glass tube 8, while the lifting component 6 lifts the glass tube 8, ensuring its stability during the cutting process. The laser cutting head 16 performs laser cutting on the glass tube 8. The lead screw module 11 and the horizontal moving platform 9 can drive the laser cutting head 16 to move horizontally in different directions, enabling the glass tube 8 to be cut according to a preset trajectory.

[0028] like Figure 1-4As shown, the lifting assembly 6 includes a cylinder 601, a push block 602, a slider 603, a positioning wheel 604, a connecting rod 605, a positioning wheel 606, a roller 607, and a spring 608. The bottom end of the cylinder 601 is fixedly connected to the inner bottom of the housing 4. The outer side of the push block 602 is fixedly connected to the output shaft of the cylinder 601. The outer side of the slider 603 is slidably connected to the inner wall of the housing 4. The two sides of the positioning wheel 604 are rotatably connected to the top of the slider 603. There are two connecting rods 605. The connecting rods 605 are rotatably connected to the inner walls of the two sides of the housing 4. The two sides of the positioning wheel 606 are rotatably connected to the top of the connecting rod 605. The two sides of the roller 607 are rotatably connected to the bottom end of the connecting rod 605. The two ends of the spring 608 are fixedly connected to the bottom ends of the two connecting rods 605 respectively.

[0029] By activating cylinder 601, the pusher block 602 is moved, which in turn pushes slider 603 upward, causing positioning wheel 604 to move upward and contact the bottom of glass tube 8. At the same time, as slider 603 moves upward, it pushes rollers 607 at both ends, causing connecting rod 605 to rotate on the inner wall of housing 4, and positioning wheels 606 to move closer to each other. Finally, positioning wheels 604 and 606 are simultaneously attached to the outer side of housing 4, supporting glass tube 8 and ensuring stability of glass tube 8 during cutting.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the positioning assembly 15 includes a support plate 701, a rotating ring 702, an annular rack 703, a connecting plate 704, an electric push rod 705, an arc-shaped clamping plate 706, a drive motor 707, and a gear 708. The bottom end of the support plate 701 is fixedly connected to the top end of the fixing plate 2. The support plate 701 is hollow inside. The outer side of the rotating ring 702 is rotatably connected to the outer side of the support plate 701. The inner wall of the annular rack 703 is fixedly connected to the outer side of the rotating ring 702. There are two connecting plates 704, which are fixedly connected to both sides of the rotating ring 702. One end of the electric push rod 705 is fixedly connected to the outer side of the connecting plate 704. The outer side of the arc-shaped clamping plate 706 is fixedly connected to the output shaft of the electric push rod 705. One end of the drive motor 707 is fixedly connected to the outer side of the support plate 701. The outer side of the gear 708 is fixedly connected to the output shaft of the drive motor 707. The top of the gear 708 meshes with the annular rack 703.

[0031] By activating two electric push rods 705, two arc-shaped clamping plates 706 can be driven to clamp and position the glass tube 8. During the cutting process, by activating the drive motor 707, the gear 708 is driven to rotate, causing the gear 708 to roll on the ring rack 703, which can drive the rotating ring 702 and the fixed glass tube 8 to rotate, and cut different positions of the glass tube 8.

[0032] Working principle: In use, first adjust the horizontal position of the lifting assembly 6 according to the length of the glass tube 8. By activating the hydraulic cylinder 3 in conjunction with the limiting rod 5, the housing 4 can be moved horizontally, thereby adjusting the position of the lifting assembly 6. Then, one end of the glass tube 8 is passed through the inside of the support plate 701, and the glass tube 8 is positioned on top of the lifting assembly 6. By activating the two electric push rods 705, the two arc-shaped clamping plates 706 can be moved horizontally towards the glass tube 8 simultaneously, so that the arc-shaped clamping plates 706 fit against the outer side of the glass tube 8, clamping and positioning the glass tube 8. At the same time, by activating the cylinder 601, the lifting assembly 6 is pushed... Block 602 moves, which in turn pushes slider 603 to move upward, and drives positioning wheel 604 to move upward and contact the bottom of glass tube 8. At the same time, as slider 603 moves upward, it can push rollers 607 at both ends, so that connecting rod 605 rotates on the inner wall of housing 4, and positioning wheels 606 move closer to each other, so that positioning wheel 604 and positioning wheel 606 are simultaneously attached to the outer side of housing 4 to lift glass tube 8. The arc-shaped clamping plate 706 clamps one end of glass tube 8 and works with lifting assembly 6 to lift glass tube 8, which can ensure the stability of glass tube 8 during the cutting process.

[0033] After the glass tube 8 is fixed, the rotating motor 14 drives the screw 15 to rotate, which in turn drives the sliding block 13 to move downward, thereby driving the laser cutting head 16 to move downward. Then, the laser cutting head 16 performs laser cutting on the glass tube 8. The lead screw module 11 and the horizontal moving platform 9 can drive the laser cutting head 16 to move horizontally in different directions, and can cut the glass tube 8 according to the preset trajectory. During the cutting process, the drive motor 707 drives the gear 708 to rotate, so that the gear 708 rolls on the ring rack 703, which can drive the rotating ring 702 to rotate. At the same time, it drives the connecting plate 704, the electric push rod 705, and the arc-shaped clamping plate 706 to rotate, thereby driving the glass tube 8 to rotate and cutting different positions of the glass tube 8.

[0034] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
