Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a fast-clamping laser cutting device. Background Technology

[0002] Laser cutting machines are advanced processing equipment that utilize high-power laser beams for cutting. These machines employ laser optics and computer numerical control (CNC) technology to guide the laser beam and focus it onto the material, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas blows away the molten or vaporized material, creating a kerf in the material and achieving the cutting purpose.

[0003] Therefore, laser cutting machines are suitable for the precise cutting of various metal materials such as stainless steel and aluminum alloys, as well as non-metallic materials such as plexiglass and wood. When cutting or drilling tubular parts with a laser cutting machine, the shapes and sizes of tubular parts vary, and the fixture needs to adapt to different specifications and shapes of tubular materials. This increases the complexity of the fixture design. Therefore, the existing Chinese utility model patent with publication number CN212264900U, "A Special Fixture for Workpieces of Laser Cutting Machines," solves the problem that existing fixtures cannot fix tubular workpieces with different outer diameters. However, this application uses a screw screw to bring the clamping block close to the tubular workpiece, so that the arc-shaped inner surface of the clamping block fits against the outer surface of the tubular workpiece. Continuing to screw the screw screw makes the clamping block tightly press against the tubular workpiece. Therefore, when clamping and fixing tubular workpieces with smaller diameters, the number of turns of the screw screw is large, which increases the operation time for fixing the tubular workpiece. Moreover, during operation, two screw screws need to be rotated simultaneously, which further increases the operation time for fixing the tubular workpiece. Utility Model Content

[0004] The purpose of this invention is to provide a fast-clamping laser cutting device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapid clamping laser cutting device includes a frame with multiple support brackets fixedly mounted on it. Each support bracket has a T-shaped sliding groove. An X-axis sliding gantry is movably mounted on the frame. A Y-axis sliding platform is movably mounted on one side of the X-axis sliding gantry. A laser generator is fixedly mounted on one side of the Y-axis sliding platform and electrically connected to an external main controller via a connecting cable. A clamping mechanism is provided on each support bracket. The clamping mechanism includes a housing with a curved block inside. A first rotating shaft is fixedly mounted in the center of the curved block, and the curved block is movably mounted within the housing via the first rotating shaft. Shaft holes are provided on both sides of the housing, and a first push rod is movably mounted within each shaft hole. A placement groove is provided in the center of the upper end of the housing, and horizontal displacement grooves are provided on both sides of the placement groove. A clamping block and a push block are movably mounted within each horizontal displacement groove. Two shaft seats are fixedly mounted on both sides of the housing, and a second push rod is movably mounted between the two shaft seats.

[0007] As a further preferred embodiment of this utility model, two insert blocks are fixedly installed at the lower end of the carrier shell. The insert blocks are T-shaped and are inserted into the T-shaped grooves in the corresponding support frame and fixed with screws.

[0008] As a further preferred embodiment of this utility model, a first positioning groove is provided on both sides of the curved block, and a second positioning groove is provided at both the upper and lower ends of the curved block.

[0009] Based on this, two first positioning grooves and a second positioning groove are set on the outside of the curved block, which can be used to realize the horizontal movement of the two first push rods by utilizing the structural width of the curved block.

[0010] As a further preferred embodiment of this utility model, a second rotating shaft is interposed between the two shaft seats, and the carrier shell is rotatably mounted on the second rotating shaft through a through hole in the lower middle part.

[0011] As a further preferred embodiment of this utility model, a partition is fixedly installed in the middle of the horizontal displacement groove, and a through hole is opened in the middle of the partition.

[0012] As a further preferred embodiment of this utility model, a V-shaped groove is provided on one side of the clamping block, and a guide shaft is fixedly installed in the middle of the other side of the clamping block. The side of the guide shaft away from the clamping block is inserted into a through hole in the partition plate. A countersunk hole is provided in the middle of the top block, and a screw is threadedly connected to one side of the guide shaft inserted into the countersunk hole.

[0013] As a further preferred embodiment of this utility model, a first compression spring and a second compression spring are respectively fitted on the outer side of the guide shaft. One side of the first compression spring abuts against one side of the clamping block, and the other side of the first compression spring abuts against one side of the partition. One side of the second compression spring abuts against one side of the top block, and the other side of the second compression spring abuts against the other side of the partition.

[0014] Based on this, the clamping block and the top block are interspersed in the same horizontal displacement groove. With the help of the guide shaft and the first and second compression springs, the countersunk hole can be pushed by the second compression spring to push the clamping block. In this way, the clamping block can be used to clamp pipes of different diameters by utilizing the compressible first and second compression springs.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this utility model, a clamping mechanism is provided on the support frame, and the installation position of the clamping mechanism can be adjusted arbitrarily.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-4 As shown, the present invention provides a rapid clamping laser cutting device, including a frame 1, on which multiple support frames 2 are fixedly installed. Each support frame 2 has a T-shaped sliding groove. An X-axis sliding gantry 3 is also movably installed on the frame 1. A Y-axis sliding platform 4 is movably installed on one side of the X-axis sliding gantry 3. A laser generator 5 is fixedly installed on one side of the Y-axis sliding platform 4, and the laser generator 5 is electrically connected to an external main controller via a connecting cable. A clamping mechanism 6 is provided on the support frame 2, and the clamping mechanism 6 includes a housing 7. Inside the housing 7... A curved block 8 is provided, and a first rotating shaft 9 is fixedly installed in the middle of the curved block 8. The curved block 8 is movably installed in the housing 7 through the first rotating shaft 9. Shaft holes 10 are opened on both sides of the housing 7. A first push rod 11 is movably installed in the shaft holes 10. A placement groove 12 is opened in the middle of the upper end of the housing 7. Horizontal displacement through grooves 13 are opened on both sides of the placement groove 12. Clamping block 14 and top block 15 are movably installed in the horizontal displacement through grooves 13 respectively. Two shaft seats 16 are fixedly installed on both sides of the housing 7. A second push rod 17 is movably installed between the two shaft seats 16.

[0024] like Figures 2-3 As shown, two insert blocks 18 are fixedly installed at the lower end of the housing 7. The insert blocks 18 have a T-shaped structure and are inserted into the T-shaped grooves in the corresponding support frame 2 and fixed with screws.

[0025] like Figures 3-4As shown, the curved block 8 has first positioning grooves 20 on both sides, and second positioning grooves 21 on both the upper and lower ends. Two first positioning grooves 20 and two second positioning grooves 21 are provided on the outer side of the curved block 8, allowing the two first push rods 11 to move horizontally using the structural width of the curved block 8. A second rotating shaft 19 is inserted between the two shaft seats 16, and the carrier shell 7 is rotatably mounted on the second rotating shaft 19 through a through hole in the lower middle part. A partition plate 23 is fixedly installed in the middle of the horizontal displacement through groove 13, and a through hole is provided in the middle of the partition plate 23. A V-shaped groove is provided on one side of the clamping block 14, and a guide shaft 24 is fixedly installed in the middle of the other side of the clamping block 14. The side of the guide shaft 24 away from the clamping block 14 is inserted into the through hole in the partition plate 23. A countersunk hole 25 is provided in the middle of the top block 15, and a countersunk hole 25 is also provided on one side of the guide shaft 24. A screw is inserted into the countersunk hole 25 and threadedly connected. A first compression spring 26 and a second compression spring 27 are respectively mounted on the outside of the guide shaft 24. One side of the first compression spring 26 abuts against one side of the clamping block 14, and the other side of the first compression spring 26 abuts against one side of the partition plate 23. One side of the second compression spring 27 abuts against one side of the top block 15, and the other side of the second compression spring 27 abuts against the other side of the partition plate 23. The clamping block 14 and the top block 15 are inserted and installed in the same horizontal displacement groove 13. With the help of the guide shaft 24 and the first compression spring 26 and the second compression spring 27, the countersunk hole 25 can push the clamping block 14 by the second compression spring 27. Thus, the clamping block 14 can clamp pipes of different diameters by using the compressible first compression spring 26 and the second compression spring 27.

[0026] It should be noted that this utility model is a quick-clamping laser cutting device. When cutting or drilling pipes, a suitable number of carrier shells 7 can be placed on the support frame 2, and the inserts 18 at the lower end of the carrier shells 7 are inserted into the corresponding T-shaped grooves. After the carrier shells 7 are adjusted to the appropriate position, the screws in the inserts 18 located on both sides of the carrier shells 7 can be screwed down, so that the lower ends of the screws in the inserts 18 abut against the bottom of the T-shaped grooves in the support frame 2, thereby fixing the carrier shells 7. When clamping the pipe, it can be placed directly into the placement groove 12 at the upper end of the carrier shell 7. Then, the operating handle 22 on one side of the first rotating shaft 9 is rotated 90 degrees. As a result, the first rotating shaft 9 drives the curved block 8 to rotate 90 degrees within the carrier shell 7. Consequently, the two second positioning grooves 21 on the outer side of the curved block 8 disengage from the corresponding first push rods 11. With the rotation of the curved block 8, the two first push rods 11 are pressed and moved to one side by the change in the outer contour of the curved block 8. Thus, the two first push rods 11 are... One push rod 11 moves within its corresponding shaft hole 10, causing the other side of the first push rod 11 to press and move one side of the corresponding second push rod 17, causing the second push rod 17 to rotate axially about the second rotating shaft 19. This, in turn, causes the upper end of the second push rod 17 to press the corresponding push block 15 to one side, thus moving the push block 15 within the horizontal displacement groove 13 and compressing the second compression spring 27 towards the partition plate 23. After the push block 15 moves towards the partition plate 23, the countersunk hole 25 within the push block 15 is located on the guide shaft 24. The upward movement causes the clamping block 14 to be pushed to one side by the extension and rebound force of the first compression spring 26. Thus, the two clamping blocks 14 quickly clamp the pipe placed in the placement groove 12, and the two first positioning grooves 20 on the outer side of the curved block 8 respectively engage with the corresponding first top rod 11 side, thereby completing the rapid fixation of the pipe. Subsequently, the X-axis sliding gantry 3, Y-axis sliding platform 4, and laser generator 5 can be activated by the external controller to realize the cutting and hole opening at different positions of the pipe.
