Technical Field

[0001] This application relates to the technical field of cutting machines, and in particular to a three-dimensional seven-axis cutting machine. Background Technology

[0002] A cutting machine is a cutting and processing equipment with high efficiency, high precision, and high processing quality. It is suitable for processing materials such as metal, plastic, ceramic, wood, and glass, and is widely used in automobile manufacturing, aerospace, military, construction, medical equipment and other fields. Most cutting machines in the current technology are three-dimensional five-axis cutting machines.

[0003] Chinese patent CN221817653U discloses a three-dimensional five-axis cutting machine, which includes a worktable, a laser head, a drive assembly, a Y-axis drive module, a Z-axis drive module, a first rotary drive component, and a second rotary drive component.

When cutting material, the drive assembly, the Y-axis drive module, the Z-axis drive module, the first rotary drive component, and the second rotary drive component drive the laser head to rotate in different directions, thereby cutting the material. However, the three-dimensional five-axis cutting machine can only cut profiles and cannot be used to cut steel pipes. Utility Model Content

[0004] To facilitate the cutting of steel pipe materials, this application provides a three-dimensional seven-axis cutting machine.

[0005] This application provides a three-dimensional seven-axis cutting machine, which adopts the following technical solution:

[0006] A three-dimensional seven-axis cutting machine includes a three-dimensional five-axis cutting machine and a feeding mechanism.

The rear chuck assembly is slidably disposed on the worktable through the power assembly and is used to drive the workpiece to be cut to rotate. The power assembly drives the workpiece to be cut to be fed through the rear chuck assembly. The workpiece to be cut is a pipe or a rod.

[0007] By adopting the above technical solution, when cutting the workpiece, the front chuck assembly and the rear chuck assembly clamp the steel pipe and jointly drive the workpiece to rotate. At the same time, the power assembly drives the workpiece to move towards the cutting mechanism through the rear chuck assembly. Then the cutting mechanism cuts the workpiece, thereby realizing the cutting of pipes or bars by the cutting machine and improving the applicability of the cutting machine.

[0008] Optionally, the front chuck assembly includes a first support block, a first chuck block, three first cylinders, three first clamping blocks, and a front rotating member. The first support block is disposed on the worktable, and a first groove is formed on the end face of the first support block away from the worktable.

[0009] By adopting the above technical solution, when the workpiece to be cut is rotated, the first cylinder is started, the first cylinder drives the first clamping block to move, the first clamping block clamps the workpiece to be cut, and then the front rotating part drives the first chuck block to rotate, and the first chuck block and the rear chuck assembly together drive the workpiece to be cut to rotate.

[0010] Optionally, the front rotating component includes a first motor, a first gear, and a first gear ring. The first motor is mounted on the first support block, the first gear is keyed to the output shaft of the first motor, and the first gear ring is mounted on the outer wall of the first chuck block and meshes with the first gear.

[0011] By adopting the above technical solution, when the workpiece to be cut is rotated, the first motor starts, the first motor drives the first gear to rotate, the first gear drives the first gear ring to rotate, the first gear ring drives the first pneumatic chuck to rotate, and the first pneumatic chuck drives the workpiece to be cut to rotate.

[0012] Optionally, the rear chuck assembly includes a second support block, a second chuck block, three second cylinders, three second clamping blocks, and a rear rotating member. The second support block is slidably mounted on the worktable via the power assembly. A second groove is formed on the end face of the second support block away from the worktable. The second chuck block is rotatably mounted in the second groove. All three second cylinders are mounted on the second chuck block. The three second clamping blocks are respectively mounted on the piston shafts of the three second cylinders. The rear rotating member is mounted on the second support block and is used to drive the second chuck block to rotate.

[0013] By adopting the above technical solution, when the workpiece to be cut is rotated, the second cylinder is started, the second cylinder drives the second clamping block to clamp the workpiece to be cut, and then the rotating part drives the second chuck block to rotate. The second chuck block and the first chuck block together drive the workpiece to be cut to rotate.

[0014] Optionally, the rear rotating component includes a second motor, a second gear, and a second gear ring. The second motor is mounted on the second support block, the second gear is keyed to the output shaft of the second motor, and the second gear ring is mounted on the outer wall of the second chuck block and meshes with the second gear.

[0015] By adopting the above technical solution, when the second chuck block rotates, the second motor starts, the second motor drives the second gear to rotate, the second gear drives the second gear ring to rotate, and the second gear ring drives the second chuck block to rotate.

The second support block drives the workpiece to be cut to move through the second chuck block.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. Existing cutting machines have no problem cutting profiles, but when cutting pipes or rods, the cutting effect is not good because the outer surface of the pipes or rods is circumferential. This application uses a first cylinder and a second cylinder to drive a first clamping block and a second clamping block respectively to fix the pipes or rods, and the rotation of the first chuck block and the second chuck block together drives the pipes or rods to rotate, thereby realizing the cutting of pipes or rods by the cutting machine and improving the applicability of the cutting machine.

[0022] 2. Existing cutting machines have rollers on the worktable to facilitate manual movement of the material to be cut. However, manual movement increases labor costs and is also inherently dangerous. This application addresses this by starting a third motor, which drives a third gear to rotate. The third gear meshes with a rack, which in turn drives a second support block to slide on a slide rail via a slider. The second support block then moves the material to be cut via a second chuck block, thus achieving automatic feeding of the material. This improves the automation level of the cutting machine, reduces labor costs, and enhances operational safety.

[0023] 3. Compared with traditional manually adjustable mechanical chucks, this application achieves automatic clamping of the material to be cut by means of cylinders and clamping blocks, thereby further improving the automation level of the cutting machine. Furthermore, since the clamping of the cylinder is more stable, the probability of the material to be cut becoming loose is reduced.

[0024] 4. The rack and pinion feeding method makes the feeding accuracy higher, and the cut materials are more compliant. At the same time, the combination of gears and racks is easier to clean, cheaper to manufacture, and has a lower replacement cost. Attached Figure Description

Three second cylinders 323 are also fixedly connected to the end face of the second chuck block 322 near the first chuck block 312. The three second cylinders 323 move along the second chuck... The blocks 322 are evenly arranged in the circumferential direction. The piston shafts of the three second cylinders 323 are all fixedly connected to the second clamping blocks 324.

A second gear ring 3253 is fixedly connected in the second annular groove 3222. The second gear ring 3253 meshes with the second gear 3252.

[0038] When the workpiece to be cut rotates, the second cylinder 323 is activated, and the second cylinder 323 drives the second clamping block 324 to clamp the workpiece to be cut.
