Description

Technical Field

[0001] This utility model relates to the field of fiber optic cutting device technology, and in particular to a fiber optic cutting head with interchangeable focusing lenses of different focal lengths. Background Technology

[0002] In the field of laser cutting, fiber optic cleavers with interchangeable focal length focusing lenses play a crucial role. As industrial production demands increasingly higher cutting precision and material adaptability, there is a need for flexibly interchangeable focusing lenses of different focal lengths to meet the cutting requirements of materials with varying thicknesses and materials. For example, in automobile manufacturing, the thickness and material of metal sheets differ in different parts. By changing the focusing lenses of the fiber optic cleaver, high-precision and high-efficiency cutting can be achieved, improving production quality and efficiency. Therefore, this device is widely used in modern industrial cutting.

[0003] Existing fiber optic cleavers with interchangeable focal length lenses typically employ a complex multi-component assembly structure to secure the focusing lens. Changing the lens requires the use of various specialized tools and the sequential disassembly of multiple tightly connected components to access and remove the focusing lens. The underlying technology is primarily based on traditional mechanical fastening methods, relying on screws, nuts, and other connectors to firmly fix the lens inside the cleaver, ensuring its stability during the cleavering process.

[0004] The disassembly and fixing process for replacing focusing lenses is extremely complex. Operators not only need to spend a lot of time familiarizing themselves with the tedious disassembly procedures, but also need to be extremely careful to avoid damaging other components due to improper operation. Moreover, because the disassembly process requires frequent use of tools in a confined space, it is very easy to accidentally scratch the lens surface, causing lens damage, which in turn affects the cutting accuracy and the overall performance of the cutting head. To address these issues, a fiber optic cutting head that can replace focusing lenses with different focal lengths is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fiber optic cutter head that can replace different focal length focusing lenses, aiming to improve the problem of complex disassembly and fixation and easy damage when replacing focusing lenses in the prior art.

[0006] To achieve the above objectives, the present invention provides a fiber optic cleaver with interchangeable focal length focusing lenses, comprising a connector, a connecting frame fixedly connected to the side wall of the connector, a focusing frame fixedly connected to the side wall of the connecting frame, a clamping assembly disposed inside the focusing frame, a cleaver body fixedly connected to the side wall of the focusing frame, and a cooling assembly disposed on the side wall of the focusing frame.

[0007] The clamping assembly includes a fixed frame, the side wall of which is slidably connected to the inside of the focusing frame, a handle fixedly connected to the side wall of the fixed frame, a groove provided inside the fixed frame, a clamping frame provided inside the fixed frame, a rubber pad fixedly connected to the side wall of the clamping frame, a telescopic rod fixedly connected to the side wall of the clamping frame, the side wall of the telescopic rod fixedly connected to the inside of the groove, and a first spring sleeved on the side wall of the telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The cooling assembly includes a protective frame, the side wall of which is fixedly connected to the side wall of the connecting frame, and a cooling box is fixedly connected to the side wall of the connecting frame.

[0010] As a further description of the above technical solution:

[0011] A water pump is installed on the side wall of the cooling box, and a connecting pipe is fixedly connected to the input end of the water pump.

[0012] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] A second spring is fixedly connected to the side wall of the fixing block, and the side wall of the second spring is fixedly connected to the inside of the protective frame.

[0020] As a further description of the above technical solution:

[0021] One end of the first spring is fixedly connected to the side wall of the clamping frame, and the other end of the first spring is fixedly connected to the inside of the groove.

[0022] Optionally,

[0023] The fiber optic cleaver with interchangeable focal length focusing lenses provided in this embodiment of the present invention has at least one of the following technical effects:

[0024] 1. In this utility model, the fixing frame is loosened by rotating the bolt, and it is pulled out of the focusing frame by the handle. The old lens is taken out and the new lens is put in. The lens squeezes the clamping frame to move it, which drives the telescopic rod to retract and squeeze the first spring. After the lens is in place, the first spring rebounds and the clamping frame clamps the lens. Its internal rubber pad prevents scratches and increases friction. This solves the problem of complicated disassembly and fixing and easy damage when changing focusing lenses. The above technical solution improves the convenience of changing focusing lenses and the stability of fixing.

[0025] 2. In this utility model, the cooling pipe is inserted between the clamping plates. When inserted, the clamping plates are squeezed, causing them to rotate within the fixing frame and compress the second spring. After being inserted to the bottom, the second spring rebounds, and the clamping plates clamp the cooling pipe to complete the fixation. This solves the problem of inconvenient maintenance caused by fixing the cooling pipe with bolts. The above technical solution improves the convenience of cooling pipe maintenance.

[0038] Reference Figure 1 - Figure 3An embodiment of this utility model provides: a fiber optic cleaver with interchangeable focal length focusing lenses, including a connector 1, a connecting frame 2 fixedly connected to the side wall of the connector 1, a focusing frame 3 fixedly connected to the side wall of the connecting frame 2, a clamping assembly disposed inside the focusing frame 3, a cleaver body 4 fixedly connected to the side wall of the focusing frame 3, and a cooling assembly disposed on the side wall of the focusing frame 3; the clamping assembly includes a fixing frame 5, the side wall of the fixing frame 5 is slidably connected to the inside of the focusing frame 3, a handle 6 fixedly connected to the side wall of the fixing frame 5, a groove 7 opened inside the fixing frame 5, a clamping frame 8 disposed inside the fixing frame 5, the clamping frame 8 is used to place the focusing lens, a rubber pad 9 fixedly connected to the side wall of the clamping frame 8, a telescopic rod 10 fixedly connected to the side wall of the clamping frame 8, the side wall of the telescopic rod 10 fixedly connected to the inside of the groove 7, a first spring 11 sleeved on the side wall of the telescopic rod 10, the first spring 11 is used for rebound reset, one end of the first spring 11 is fixedly connected to the side wall of the clamping frame 8, and the other end of the first spring 11 is fixedly connected to the inside of the groove 7;

[0039] When replacing the focusing lens, rotate the bolt to release the fixing frame 5. The bolt serves to secure the fixing frame 5, fixing it inside the focusing frame 3 to prevent displacement of the focusing lens during cutting, which would affect cutting accuracy. After releasing the fixing by rotating the bolt, pull the fixing frame 5 out of the focusing frame 3 using the handle 6. The handle 6 facilitates the operator's application of force. Then, remove the lens inside for replacement. Place the new lens between the clamping frames 8. The clamping frames 8 fix the lens, ensuring its accurate position within the focusing frame 3, thereby ensuring accurate laser focusing. The lens placement process... The clamping frame 8 is squeezed and moved. The movement of the clamping frame 8 causes the telescopic rod 10 to retract and simultaneously compress the first spring 11. The telescopic rod 10 acts as a guide to ensure the stability of the movement of the clamping frame 8, while the first spring 11 provides elastic restoring force. When the lens is placed, the first spring 11 rebounds, causing the clamping frame 8 to clamp the lens tightly. It can automatically adapt to different sized lenses to ensure that the lens is fixed. At the same time, the rubber pad 9 fixed inside the clamping frame 8 increases the friction on the lens, preventing the lens from loosening due to vibration during the cutting process. The rubber pad 9 also prevents the clamping frame 8 from scratching the lens and protects the optical surface of the lens.

[0040] Reference Figure 1 , Figure 4 and Figure 5The cooling assembly includes a protective frame 12, the side wall of the protective frame 12 is fixedly connected to the side wall of the connecting frame 2, the side wall of the connecting frame 2 is fixedly connected to a cooling box 13, the side wall of the cooling box 13 is provided with a water pump 14, the input end of the water pump 14 is fixedly connected to a connecting pipe 15, the side wall of the connecting pipe 15 is fixedly connected to the side wall of the cooling box 13, and the output end of the water pump 14 is fixedly connected to a cooling pipe 16. The cooling pipe 16 is used to remove the heat generated by the cutting of the focusing frame 3, so as to avoid the performance of the focusing lens and the cutting accuracy due to high temperature. The inside of the protective frame 12 is fixedly connected to a fixing frame 17, the inside of the fixing frame 17 is rotatably connected to a clamping plate 18, the side wall of the cooling pipe 16 is slidably connected between the clamping plates 18, the side wall of the clamping plate 18 is fixedly connected to a fixing block 19, the side wall of the fixing block 19 is fixedly connected to a second spring 20, and the side wall of the second spring 20 is fixedly connected to the inside of the protective frame 12.

[0041] The cooling pipe 16 is inserted between the clamping plates 18. During the movement of the cooling pipe 16, it squeezes the clamping plates 18, causing them to rotate inside the fixing frame 17, and compresses the second spring 20 to contract it. The second spring 20 stores elastic potential energy. When the cooling pipe 16 is fully inserted, the second spring 20 rebounds, causing the clamping plates 18 to clamp the cooling pipe 16 and fix it. This fixing method facilitates the installation and removal of the cooling pipe 16 and makes it easy to maintain the cooling system. When the cutting device starts working, it generates heat. The water pump 14 draws the cooling water stored in the cooling tank 13 through the connecting pipe 15 and delivers it to the cooling pipe 16. The water pump 14 provides power to ensure that the cooling water can circulate in the system. The connecting pipe 15 connects the cooling tank 13 and the cooling pipe 16 to realize the delivery of cooling water. The cooling water in the cooling pipe 16 exchanges heat with the heat generated in the focusing frame 3, taking away the heat generated by the cutting in the focusing frame 3, reducing the temperature of the focusing frame 3, and avoiding the impact of high temperature on the performance of the focusing lens and the cutting accuracy. The cooling water after heat exchange returns to the cooling tank 13 through the cooling pipe 16 for circulation. Through this circulating cooling method, the aging rate of the device is slowed down, the service life of the device is improved, and the cutting device can be operated stably for a long time.

[0042] Working principle: When replacing the focusing lens, turn the bolt to release the fixing frame 5, and then pull the fixing frame 5 out from the focusing frame 3 through the handle 6 to take out the lens for replacement. When the new lens is placed between the clamping frames 8, the clamping frames 8 will be squeezed and moved during the insertion process. The movement of the clamping frames 8 will cause the telescopic rod 10 to retract and squeeze the first spring 11. After the lens is placed, the first spring 11 will rebound, causing the clamping frames 8 to clamp the lens tightly. At the same time, the rubber pad 9 fixed inside the clamping frames 8 increases the friction on the lens and prevents the clamping frames 8 from scratching the lens.

[0043] The cooling pipe 16 is inserted between the clamping plates 18. During the movement of the cooling pipe 16, it squeezes the clamping plates 18, causing them to rotate inside the fixing frame 17, and squeezes the second spring 20 to contract it. When the cooling pipe 16 is fully inserted, the second spring 20 rebounds, causing the clamping plates 18 to clamp the cooling pipe 16 and fix it. When the cutting device starts working, it generates heat. The water pump 14 draws the cooling water stored in the cooling box 13 through the connecting pipe 15 and delivers it to the cooling pipe 16 to exchange heat with the heat generated in the focusing frame 3. After the heat exchange, the cooling water returns to the cooling box 13 through the cooling pipe 16 for circulation, which slows down the aging of the device and improves its service life.

[0044] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
