Description
Technical Field
[0001] This utility model relates to the field of optical fiber processing equipment technology, specifically to an optical fiber laser cutting device with a fast clamping structure. Background Technology
[0002] In the field of fiber optic processing, the application of fiber laser cutting equipment is becoming increasingly widespread. However, traditional fiber laser cutting equipment has many problems when processing sheet metal. On the one hand, in terms of sheet metal clamping, existing clamping structures are often cumbersome to operate and difficult to achieve rapid clamping of sheet metal. For example, some devices require multiple complex steps and the coordination of parts to complete the clamping, which not only consumes time but also reduces production efficiency and cannot meet the needs of modern high-efficiency production. Moreover, during the clamping process, the clamping body and top block of the traditional clamping structure often have direct hard contact and friction with the sheet metal surface, which can easily leave scratches, indentations and other damage on the sheet metal surface, seriously affecting the surface quality of the sheet metal. For some fiber optic processing products with high surface quality requirements, this greatly reduces the product yield.
[0003] On the other hand, during the cutting process, traditional devices do not provide sufficient clamping strength for the sheet metal. When the laser cutting head is working, the vibration generated during cutting can easily cause the sheet metal to shift, leading to a decrease in cutting accuracy and failing to meet the requirements of high-precision fiber laser cutting. In addition, traditional devices have poor versatility and are difficult to adapt to sheets of different thicknesses and widths. When faced with diverse fiber laser cutting needs, it is often necessary to frequently change equipment or make complex adjustments, which increases production costs and production cycles. Therefore, it is urgent to design a fiber laser cutting device with a fast clamping structure to solve the above problems. Utility Model Content

[0006] Preferably, the top block is a trapezoidal platform, and the bottom surface of the top block and the front of the long side of the clamping body are provided with mounting grooves. Guide wheel two and guide wheel one are movably mounted in the mounting grooves through fixed shafts, and the surface of the guide wheels is provided with anti-scratch rubber sleeves.
[0007] Preferably, a limiting block is fixedly installed at the front end of the limiting rod, and a limiting hole is provided in the top block, and the limiting rod is movably installed in the limiting hole.
[0008] Preferably, the diameter of the limiting hole is the same as the diameter of the limiting block, a stop block is provided near the edge of the limiting hole, the diameter of which is the same as the diameter of the limiting rod, and a spring is fixedly installed between the clamping body and the top block, the spring being sleeved on the limiting rod.
[0009] Preferably, the top pressing mechanism includes a device body, a sliding groove is provided in the middle of the device body, a slider is movably installed in the sliding groove, the slider is fixedly installed at the bottom of the clamping body, the slider is movably installed on a screw through a thread, the screw is a bidirectional screw, and an adjusting wheel is fixedly installed on the right side of the screw.
[0010] Preferably, the clamping body has an oil storage cavity filled with hydraulic oil. A sealing plate is movably installed in the oil storage cavity. Two sets of fixing rods are fixedly installed on the right side of the sealing plate. A side plate is fixedly installed at the other end of the fixing rods. A second slider is fixedly installed at the bottom of the side plate. The second slider is movably installed in a second sliding groove, which is located on the upper surface of the long side of the clamping body.
[0011] Preferably, the clamping body is provided with an oil guide groove, and a corrugated pipe is fixedly installed on the other side of the oil guide groove. The other end of the corrugated pipe is fixedly installed on the top block. The top block is also provided with an oil guide groove.

A second limiting block is fixedly installed on the upper end of the top rod. A pressure plate is fixedly installed on the lower end of the top rod. The pressure plate is a frustum-shaped rubber pad.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This fiber laser cutting device with a rapid clamping structure utilizes a rapid clamping mechanism. By pressing down on the sheet metal, the top block, being a trapezoidal platform, moves backward along the limiting rod, allowing it to fall between the clamping body and the top block. This achieves rapid clamping of the sheet metal. Simultaneously, the guide wheel design ensures that the guide wheel rolls in contact with the sheet metal surface during clamping, preventing direct hard friction between the clamping body and the top block and the sheet metal surface. This effectively prevents scratches, indentations, and other damage to the sheet metal surface, ensuring its surface quality.
[0014] 2. This fiber laser cutting device with a rapid clamping structure utilizes a top-pressure mechanism. By rotating an adjusting wheel and using a bidirectional screw, two sets of clamping bodies move inwards. As the clamping bodies move inwards, the side plates move outwards under pressure, pushing the sealing plate in the oil reservoir and squeezing the hydraulic oil. The hydraulic oil transmits pressure through the oil guide groove and bellows, causing the push rod to move downwards within the oil guide groove of the top block. This drives the frustum-shaped rubber pad pressure plate to press firmly against the surface of the plate, improving the clamping strength and preventing plate displacement during cutting, thus ensuring cutting accuracy. Furthermore, by adjusting the clamping body spacing and the different top-pressure lengths of the push rod, it can adapt to plates of different thicknesses and widths, greatly improving the device's versatility and meeting diverse fiber laser cutting processing needs.

[0021] 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.
[0022] Example 1:
[0023] Based on existing technology, traditional fiber laser cutting equipment often suffers from cumbersome clamping structures when processing sheet metal. These structures are difficult to operate quickly, requiring multiple complex steps and component coordination to achieve clamping. This not only wastes time but also reduces production efficiency, failing to meet the demands of modern high-efficiency production. Furthermore, during clamping, the clamping body and top block often directly rub against the sheet metal surface, easily leaving scratches, indentations, and other damage, severely impacting surface quality. For fiber laser products with high surface quality requirements, this significantly reduces yield. Therefore, this device is equipped with a rapid clamping mechanism. Please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: a fiber laser cutting device with a quick clamping structure, including a device body 1, cutting frames 2 movably mounted on both sides of the device body 1, a laser cutting head 3 movably mounted on the cutting frames 2, a driving device 4 fixedly mounted on the side of the cutting frames 2, and a clamp 5 movably mounted inside the device body 1; the fiber laser cutting device with a quick clamping structure includes a quick clamping mechanism and a top pressing mechanism, the quick clamping mechanism includes the device body 1, a clamp body 201 movably mounted inside the device body 1, the clamp body 201 is "L" shaped, a limit rod 205 is fixedly mounted on the front of the short side of the clamp body 201, and a top block 202 is movably mounted on the limit rod 205.
[0024] The top block 202 is a trapezoidal platform. The bottom surface of the top block 202 and the front of the long side of the clamping body 201 are provided with mounting grooves 209. Guide wheel 204 and guide wheel 203 are respectively movably mounted in the mounting grooves 209 through fixed shafts.
[0025] The front end of the limiting rod 205 is fixedly installed with a limiting block 206, and the top block 202 is provided with a limiting hole 207. The limiting rod 205 is movably installed in the limiting hole 207.
[0026] The diameter of the limiting hole 207 is the same as the diameter of the limiting block 206. A stop block is provided near the edge of the limiting hole 207, and its diameter is the same as the diameter of the limiting rod 205. A spring 208 is fixedly installed between the clamping body 201 and the top block 202, and the spring 208 is sleeved on the limiting rod 205.
[0027] In use, place the plate to be cut on top of the clamp inside the main body of the device and press it down. Since the top block 202 is a trapezoidal platform structure, the pressure on the plate will cause it to move backward along the limiting rod 205. When the plate falls onto the clamp body 201, the guide wheel 204 in the mounting groove 209 on the bottom surface of the top block 202 and the guide wheel 203 in the mounting groove 209 on the long side of the clamp body 201 will contact and roll with the surface of the plate. This prevents damage to the surface of the plate and achieves quick clamping. During this process, the spring 208 plays a buffering and restoring role. After the plate is placed, the spring 208 will give the top block 202 a certain forward pushing force, making the top block 202 fit more tightly with the plate. At the same time, the limiting block 206 and the stop in the limiting hole 207 cooperate with each other to limit the movement range of the top block 202 and ensure its stable operation.
[0028] Example 2:
[0029] Based on Example 1, the traditional device lacks sufficient clamping strength for the sheet metal during the cutting process. When the laser cutting head is working, the vibration generated during cutting can easily cause the sheet metal to shift, leading to a decrease in cutting accuracy and failing to meet the requirements of high-precision fiber optic cutting. Furthermore, the traditional device has poor versatility and is difficult to adapt to sheets of different thicknesses and widths. When facing diverse fiber optic cutting needs, frequent equipment changes or complex adjustments are often required, increasing production costs and time. Therefore, this device is equipped with a top-pressure mechanism. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a fiber laser cutting device with a fast clamping structure. The top pressing mechanism includes a device body 1. A slide groove 304 is provided in the middle of the device body 1. A slider 303 is movably installed in the slide groove 304. The slider 303 is fixedly installed at the bottom of the clamping body 201. The slider 303 is movably installed on the screw 302 by a thread. The screw 302 is a bidirectional screw. An adjusting wheel 301 is fixedly installed on the right side of the screw 302.
[0030] The clamping body 201 is provided with an oil storage chamber 310, which is filled with hydraulic oil. A sealing plate 309 is movably installed in the oil storage chamber 310. Two sets of fixing rods 308 are fixedly installed on the right side of the sealing plate 309. A side plate 307 is fixedly installed at the other end of the fixing rods 308. A second slider 306 is fixedly installed at the bottom of the side plate 307. The second slider 306 is movably installed in a second slide groove 305, which is located on the upper surface of the long side of the clamping body 201.
[0031] The clamp body 201 is provided with an oil guide groove 311. A corrugated pipe 312 is fixedly installed on the other side of the oil guide groove 311. The other end of the corrugated pipe 312 is fixedly installed on the top block 202. The top block 202 is also provided with an oil guide groove. The upper and lower ends of the oil guide groove in the vertical direction are provided with limiting edges 313. A top rod 315 is movably installed between the limiting edges 313. A limiting block 314 is fixedly installed on the upper end of the top rod 315. A pressure plate 316 is fixedly installed on the lower end of the top rod 315. The pressure plate 316 is a frustum-shaped rubber pad.
[0032] According to the thickness and width of the plate, the spacing of the clamping body 201 is adjusted by rotating the adjusting wheel 301. The adjusting wheel 301 drives the bidirectional screw 302 to rotate, causing the slider 303 installed on the screw 302 to move in the groove 304, thereby driving the clamping body 201 to move. When the clamping body 201 moves inward, the side plate 307 moves outward under the pressure of the plate. The fixing rod 308 fixed on the side plate 307 pushes the sealing plate 309, squeezing the hydraulic oil in the oil storage chamber 310. The hydraulic oil transmits pressure through the oil guide groove 311 and the bellows 312, causing the top rod 315 to move down in the oil guide groove of the top block 202. The frustum-shaped rubber pad pressure plate 316 at the lower end of the top rod 315 presses the plate surface, improving the clamping firmness and preventing the plate from shifting during cutting. The limiting edge 313 and the limiting block 314 limit the movement range of the top rod 315 to ensure its normal operation.
[0033] After clamping and pressing the plate, the drive device 4 is started. The drive device 4 drives the cutting frame 2 to move, so that the laser cutting head 3 installed on the cutting frame 2 is aligned with the position to be cut on the plate and cuts according to the preset cutting path. During the cutting process, the stable clamping structure ensures that the plate will not be displaced due to cutting vibration, thus ensuring cutting accuracy.
