Technical Field

[0001] This utility model relates to the field of aluminum tube processing technology, and in particular to an aluminum tube laser cutting positioning frame. Background Technology

[0002] Aluminum tubes are widely used in industrial products, aerospace, automotive manufacturing, and furniture and building materials due to their advantages such as light weight, corrosion resistance, and high strength. In these applications, aluminum tubes usually need to be cut according to design dimensions, and laser cutting has become the preferred process due to its high precision and high efficiency.

[0003] However, the positioning frame of the transmission is not only difficult to quickly position and clamp the tube, but also has low positioning efficiency, making it difficult to adapt to the pace of mass production. At the same time, the jaws of the traditional positioning frame can only provide radial clamping force and lack effective axial limiting. Under the high-speed movement and impact of the laser cutting head, the tube is prone to axial movement or circumferential rotation, resulting in tilted cuts, large dimensional errors, and even scrapping of the tube or damage to the equipment. It is difficult to guarantee the quality, efficiency and safety of aluminum tube laser cutting. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please see Figure 1 - Figure 5 This utility model provides a technical solution: a positioning frame for laser cutting of aluminum tubes, including a support frame 1, a support 2 fixedly connected to the top of the support frame 1, a slide groove 3 opened on the support 2, a slide rail 4 fixedly connected to the top of the support 2, the slide rail 4 being located outside the slide groove 3, positioning mechanisms 6 symmetrically arranged on the top of the support 2, a pad 11 fixedly connected to the top of the support 2, the pad 11 being located to the left of the slide rail 4, the left positioning mechanism 6 fixedly connected to the pad 11, and the bottom of the right positioning mechanism 6 fixedly connected to a slide block 5, the inner wall of the slide block 5 being slidably connected to the outer wall of the slide rail 4; two sets of positioning mechanisms 6 are provided, symmetrically arranged on the top of the support 2, the left positioning mechanism 6 being fixedly connected to the pad 11 by bolts, the pad 11 being able to keep the central axes of the two positioning mechanisms 6 on the same horizontal line, the bottom of the right positioning mechanism 6 being fixedly connected to the slide block 5, so that it can move together with the slide block 5, thereby adjusting the distance between the two positioning mechanisms 6 to adapt to the positioning requirements of aluminum tubes of different lengths; The positioning mechanism 6 includes a base 601, a protective cylinder 602 fixedly connected to the top of the base 601, a fixed jaw 603 fixedly connected to the bottom of the inner wall of the protective cylinder 602, an adjusting screw 605 threadedly connected to the top of the protective cylinder 602, and a movable jaw 604 slidably connected to the top of the inner wall of the protective cylinder 602. The bottom end of the adjusting screw 605 is rotatably connected to the inner wall of the movable jaw 604. The protective cylinder 602 is a hollow cylindrical structure with an inner diameter slightly larger than the outer diameter of the aluminum tube to be cut. The device is equipped with a movable jaw 604, which is also arc-shaped and is positioned vertically opposite to the fixed jaw 603. The arc-shaped surface is adapted to the outer wall of the aluminum tube to be cut, and can fit tightly against the outer wall of the aluminum tube to enhance the support of the aluminum tube. When the adjusting screw 605 is rotated, the adjusting screw 605 can drive the movable jaw 604 to move up and down along the inner wall of the protective cylinder 602 under the action of the thread, thereby adjusting the distance between the movable jaw 604 and the fixed jaw 603 to achieve clamping or loosening of the aluminum tube to be cut. A fixing bracket 606 is fixedly connected to the outer wall of the protective cylinder 602. A fixing plate 607 is fixedly connected to the outer wall of the fixing bracket 606. An electric push rod 608 is fixedly connected to the inner wall of the fixing plate 607. A limiting plate 609 is fixedly connected to the outer wall of the fixing jaw 603. Limiting holes are symmetrically opened on the limiting plate 609. A connecting plate 610 is fixedly connected to the output end of the electric push rod 608. A limiting rod 611 is fixedly connected to the outer wall of the connecting plate 610. The outer wall of the limiting rod 611 is slidably connected to the inner wall of the limiting hole. When the electric push rod 608 is working, its output end can drive the connecting plate 610 to move along the axial direction of the protective cylinder 602. The limiting rod 611 slides in the limiting hole, providing guidance for the movement of the connecting plate 610 and preventing the connecting plate 610 from deviating. The abutment plate 612 is made of elastic material and can play a buffering role when in contact with the end of the aluminum tube, avoiding damage to the aluminum tube. The diameter of the abutment plate 612 is the same as the inner diameter of the protective cylinder 602. When the aluminum tube is inserted into the protective cylinder 602, the electric push rod 608 pushes the abutment plate 612 to move, so that the abutment plate 612 is tightly abutted against the end of the aluminum tube, further restricting the movement of the aluminum tube in the axial direction and ensuring the accuracy of the aluminum tube positioning. The inner wall of the connecting plate 610 is fixedly connected to an abutment plate 612, the diameter of which is the same as the inner diameter of the protective cylinder 602. A drive mechanism is provided on the support frame 1. The drive mechanism includes a motor 7 and a fixed base 10. Both the motor 7 and the fixed base 10 are fixedly connected to the bottom of the support 2. A lead screw 8 is fixedly connected to the output end of the motor 7. The lead screw 8 is located below the slide groove 3. The end of the lead screw 8 away from the motor 7 is rotatably connected to the inner wall of the fixed base 10. A movable base 9 is fixedly connected to the bottom of the slide 5. The inner wall of the movable base 9 is threadedly connected to the outer wall of the lead screw 8. The end of the lead screw 8 away from the motor 7 is rotatably connected to the inner wall of the fixed base 10 through a bearing to ensure the stability of the lead screw 8 during rotation. The drive mechanism is used to drive the right positioning mechanism 6 to move. The motor 7 has the characteristics of high control precision and stable operation. It can accurately control the moving distance of the right positioning mechanism 6. In use, the motor 7 controls the lead screw 8 to rotate forward and backward, thereby accurately controlling the movable base 9 together with the slide 5 and the right positioning mechanism 6 to move left and right.

[0017] Working principle: In use, firstly, based on the length of the aluminum tube to be cut, start the motor 7. The motor 7 drives the lead screw 8 to rotate, causing the moving seat 9 to move the right-side positioning mechanism 6 along the slide rail 4 to the appropriate position. Then, insert both ends of the aluminum tube to be cut into the protective cylinders 602 of the two positioning mechanisms 6 respectively, so that the outer wall of the aluminum tube fits against the arc-shaped surface of the fixed jaws 603. Next, rotate the adjusting screw 605 to drive the movable jaws 604 downward until the movable jaws 604 fit tightly against the outer wall of the aluminum tube, clamping the aluminum tube. Finally, start the electric push rod 608, which pushes the abutment plate 6. Move 12 to make the abutment plate 612 tightly abut against the end of the aluminum tube, completing the positioning of the aluminum tube and preventing axial movement of the aluminum tube during cutting. After positioning and clamping, the laser cutting machine can be started for processing. During the cutting process, the positioning mechanism 6 and the drive mechanism can ensure that the aluminum tube always maintains a stable positioning state, ensuring the cutting quality of the cutting surface. After cutting, first control the electric push rod 608 to retract, so that the abutment plate 612 leaves the end face of the aluminum tube. Then, turn the adjusting screw 605 in the opposite direction to loosen the movable jaw 604, and the cut aluminum tube can be taken out, effectively improving the accuracy and efficiency of aluminum tube cutting.
