Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide laser technology, specifically a quick-disassembly carbon dioxide laser tube lens. Background Technology

[0002] As a core component in many fields such as laser processing and medicine, the performance of the lenses and the ease of maintenance of carbon dioxide laser tubes directly affect the efficiency of the entire system. During long-term use, the lenses are susceptible to contamination and damage, requiring frequent replacement.

[0003] Traditional fixing methods: The common threaded lens fastening structure presses the lens into the lens barrel by rotating the thread, which requires multiple twists when disassembling; some simple devices use glue to stick the lens, which is convenient for initial installation, but it is difficult to clean the residual glue once the lens needs to be replaced.

[0004] However, existing technologies commonly use threads and glue to fix lenses, which makes installation and disassembly time-consuming. In order to solve the problem of the time-consuming installation and disassembly in the existing technology, which increases downtime, this application proposes to set a collar inside the lens barrel and set a locking block on the collar to restrict the position of the lens. By driving the locking block to rotate, the lens can be quickly disassembled, thereby reducing the installation and disassembly time and avoiding long downtime. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The present invention relates to a quick-release carbon dioxide laser tube lens, comprising a lens barrel 1 and a lens body 3. A nozzle 2 is provided at the lower end of the lens barrel 1. A collar 4 is provided inside the lens barrel 1. A fixing component is provided between the collar 4 and the lens barrel 1. A limit ring 12 is provided on the inner side of the collar 4. Sealing gaskets are provided at both the upper and lower ends of the limit ring 12. A locking block 6 is rotatably mounted at the lower end of the collar 4. An installation groove 7 is provided at the lower end of the collar 4. The locking block 6 is rotatably mounted with the installation groove 7. The locking block 6 is set in a "Z" shape and the lower end of the locking block 6 is chamfered. A reset component is provided on the locking block 6. The lens body 3 is located between the locking block 6 and the limit ring 12.

[0024] Combination Figure 2 , Figure 3 As shown, the fixing component includes a threaded ring 5, which is installed on the outer ring of the collar 4. The threaded ring 5 is threadedly connected to the lens barrel 1. The collar 4 and the lens barrel 1 are connected by the threaded ring 5, so that the collar 4 can be replaced and the effect of the device is avoided due to wear and tear.

[0025] Two drive blocks 14 are symmetrically arranged at the lower end of the threaded ring 5. Each drive block 14 is provided with a drive groove 15. The drive blocks 14 and the threaded ring 5 are integrally set. By inserting one end of the strip tool into the drive groove 15, the force is applied to the drive block 14 when the strip tool is rotated, and the threaded ring 5 is rotated through the drive block 14, which facilitates the installation and disassembly of the workers.

[0026] See Figure 3 , Figure 4As shown, the reset assembly includes a telescopic rod 10. One end of the telescopic rod 10 is mounted on a threaded ring 5, and the other end is mounted on a slider 11. The slider 11 is positioned above the locking block 6. A spring 9 is fitted onto the telescopic rod 10. When the slider 11 is pushed by the locking block 6, the slider 11 drives one end of the telescopic rod 10 and the spring 9 to move. The spring 9 is compressed and stores force. The telescopic rod 10 restricts the compression direction of the spring 9 to prevent the spring 9 from bending. When the push of the locking block 6 is removed, the spring 9 pushes the slider 11 to move in the opposite direction. The slider 11 pushes the locking block 6 to rotate in the opposite direction and reset.

[0027] In this embodiment, a groove 8 is provided on the threaded ring 5, and the telescopic rod 10 and the spring 9 are both provided inside the groove 8. A guide groove 16 is provided on the inner wall of the groove 8. The slider 11 is slidably disposed with the guide groove 16. The guide groove 16 restricts the movement direction and position of the slider 11, thereby improving the stability of the slider 11 during movement.

[0028] Combination Figure 2 , Figure 3 As shown, a tension spring 13 is provided between the upper end of the collar 4 and the limiting ring 12. One end of the tension spring 13 is installed on the limiting ring 12, and the other end of the tension spring 13 is installed on the collar 4. When the lens body 3 is installed, the lens body 3 pushes the limiting ring 12 to slide inside the collar 4. The limiting ring 12 stretches the tension spring 13, and the tension of the tension spring 13 on the limiting ring 12 achieves the pressing of the lens body 3. When the lens body 3 is disassembled, after the locking block 6 separates from the lens body 3, the tension spring 13 drives the limiting ring 12 to move, and the limiting ring 12 pushes the lens body 3 to automatically disengage from the collar 4.

[0029] The implementation principle is as follows: When it is necessary to disassemble the lens body 3, firstly, remove the nozzle 2 from the lens barrel 1, then place the annular disassembly tool into the lens barrel 1, and then move the annular disassembly tool. The annular disassembly tool pushes the upper end of the locking block 6 to move, the upper end of the locking block 6 pushes the slider 11 to move, and the slider 11 pushes the spring 9 and the telescopic rod 10 to compress and store force until the lower end of the locking block 6 separates from the lens body 3, thereby releasing the limiting effect on the lens body 3. The lens body 3 is then installed by directional operation. When it is necessary to disassemble the collar 4, replace the annular disassembly tool with a strip tool, insert one end of the strip tool into the drive groove 15, and rotate the strip tool. The strip tool drives the drive block 14 to rotate, the drive block 14 drives the threaded ring 5 to rotate, and the threaded ring 5 drives the collar 4 to rotate, thereby realizing the disassembly of the collar 4. The collar 4 is then installed by reverse operation.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
