Description

Technical Field

[0001] This utility model relates to the technical field of round tube cutting clamping devices, and in particular to a round tube cutting clamping device. Background Technology

[0002] Round tube cutting is a technology that uses specialized equipment (such as laser cutting machines, plasma cutting machines, etc.) to precisely process round metal or non-metal tubes. By melting at high temperatures or removing material through mechanical friction, it can achieve various cutting shapes such as straight lines, oblique lines, and irregular holes to meet the needs of pipe connection, structural assembly, etc. This process has the advantages of high cutting accuracy, smooth edges, and high efficiency, and is widely used in fields such as machinery manufacturing, building decoration, and automotive industry. In real-world metal tube cutting, the reaction force generated by the high-speed rotating blade or laser contacting the tube can easily cause the tube to vibrate, leading to skewed cuts, increased burrs, and even disruption of the cutting path continuity. This vibration problem is particularly prominent in thin-walled tubes or workpieces with a large length-to-diameter ratio, severely affecting processing accuracy and efficiency. Therefore, this invention proposes a tube cutting clamping device to solve the above problems. Utility Model Content

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a round tube cutting and clamping device, including a worktable 1, a drive arm 2, and an assembly frame 3. The top of the worktable 1 is provided with the drive arm 2, and a cutting mechanism is installed on the drive arm 2. A support block is fixedly connected to the top of the worktable 1, and an assembly frame 3 is fixedly connected to the top of the worktable 1. The assembly frame 3 is provided with a clamping mechanism that matches the round tube. The metal round tube is placed on the support block on the top of the worktable 1, and the metal round tube is pushed to move towards the cutting area until the cutting position on the metal round tube coincides with the position of the cutting mechanism. The metal round tube is cut by the cutting mechanism, and the clamping mechanism clamps the metal round tube during the cutting process to avoid vibration during cutting and ensure the quality of the metal round tube cutting. When feeding, the clamping mechanism releases the metal round tube.

[0016] The clamping mechanism includes a drive cylinder 4, gears 5, grippers 6, and connecting arms 8. The drive cylinder 4 is rotatably mounted on one side of the assembly frame 3. Gears 5 are symmetrically hinged on both sides of the assembly frame 3. Gears 6 are fixedly connected to one side of each gear 5. The output end of the drive cylinder 4 is fixedly connected to the connecting arm 8. One end of the connecting arm 8 is hinged to the bottom end of one of the grippers 6. A support block 7 is fixedly connected to the top of the assembly frame 3. The top ends of the two grippers 6 are respectively attached to the two sides of the round tube. The output end of the drive cylinder 4 can drive the connecting arm 8 to move horizontally back to its original position. The output end of the drive cylinder 4 drives one of the gears 5 to rotate forward and backward through the connecting arm 8. The two gears 5 mesh with each other, which causes the grippers 6, which are connected to the gears 5, to move closer or further apart, thereby clamping or releasing the metal tube. This locks the position of the metal round tube, avoids vibration during cutting, and ensures the quality of the metal round tube cutting. The drive cylinder 4 can adaptively adjust its own position to avoid interference.

[0017] The cutting mechanism includes a rotary motor 13, a cutting blade 14, a retaining cover 15, a pulley 16, and a belt 17. The rotary motor 13 is fixedly installed at one end of the drive arm 2, and the cutting blade 14 is rotatably connected to the other end of the drive arm 2. The output end of the rotary motor 13 and one end of the cutting blade 14 are both fixedly connected to pulleys 16. The two pulleys 16 are connected to each other by a belt 17. The retaining cover 15 is fixedly installed at the other end of the drive arm 2. The inner side of the retaining cover 15 wraps around the cutting blade 14. The rotary motor 13 can drive the pulley 16 at its output end to rotate. The two pulleys 16 rotate synchronously through the belt 17. The cutting blade 14 is connected to the other pulley 16 as a whole. The rotary motor 13 can drive the cutting blade 14 to rotate at high speed. After the metal tube contacts the cutting blade 14, it is cut. The pulley 16 and the belt 17 are toothed pulleys and toothed belts, which are suitable for high-precision transmission.

[0018] A through groove is provided on one side of the workbench 1. Inside the through groove is a rotating mechanism that matches the drive arm 2. The rotating mechanism includes a rotating cylinder 12 and a connecting arm. The bottom of the drive arm 2 is hinged to the top of the workbench 1 via a rotating seat 11. The rotating cylinder 12 is rotatably connected inside the through groove. The output end of the rotating cylinder 12 is fixedly connected to the connecting arm. One end of the connecting arm is hinged to one end of the drive arm 2 via a pin. When the output end of the rotating cylinder 12 moves in extension and retraction, it drives the drive arm 2 to rotate in both directions around the center of the rotating seat 11 via the connecting arm. This drives the cutting blade 14 at one end of the drive arm 2 to approach the metal tube and cut it, or drives the cutting blade 14 away from the cut metal tube.

[0019] A guide rail 9 is fixedly installed at the cutting point on one side of the workbench 1. A movable trolley 10 is provided on the inner side of the workbench 1. The upper part of the movable trolley 10 is connected to the bottom end of the guide rail 9. The cut metal tubes fall down along the guide rail 9 into the interior of the movable trolley 10. After the interior of the movable trolley 10 is full of metal tubes, the movable trolley 10 is pulled out from the inner side of the workbench 1 for centralized processing of the metal tubes. Then the movable trolley 10 is put back into the interior of the workbench 1.

[0020] In this round tube cutting clamping device, the output end of the drive cylinder 4 can drive the connecting arm 8 to move horizontally to reset. The output end of the drive cylinder 4 drives one of the gears 5 to rotate forward and backward through the connecting arm 8. The two gears 5 mesh with each other, which drives the gripper 6 connected to the gear 5 to move closer or further apart, so as to clamp or release the metal tube. It can lock the position of the metal round tube, avoid vibration during cutting, and ensure the quality of metal round tube cutting. The drive cylinder 4 can adaptively adjust its own position to avoid interference.
