[0002] In the manufacturing and repair of rotating equipment such as pumps, fans, and turbomachinery, the volute flow channel is a key component. Its complex structure and varied curvature place high demands on machining precision and surface quality. Especially during repair or custom production, efficient and precise cutting of the volute flow channel is crucial for ensuring equipment performance.

[0003] Traditional cutting machines have certain limitations. For example, early methods involved manual marking followed by gas cutting or angle grinding, resulting in low efficiency, poor precision, and high labor intensity, making it difficult to meet the requirements of modern industry for high-precision assembly and fluid dynamics performance. Subsequent general-purpose CNC cutting equipment, such as ordinary CNC flame / plasma cutting machines, are suitable for cutting planar or regular contours, but have poor adaptability to three-dimensional spatial curves, spirals, or irregularly shaped volute flow channels.

[0004] Therefore, for volutes and similar products with complex geometries, difficult cutting path planning, and diverse materials, the cutting equipment needs to have good mobility and adaptability. This utility model is thus developed. Utility Model Content

[0018] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0019] like Figure 1-7 As shown, a multi-functional cutting machine includes a frame 1. A workpiece mounting assembly and a Y-axis lifting assembly are respectively mounted on the front and rear sides of the frame 1. An X-axis moving assembly is mounted on the Y-axis lifting assembly, and a cutting assembly is mounted on the X-axis moving assembly. In this invention, the workpiece mounting assembly can swing back and forth, and the workpiece mounted on the workpiece mounting assembly can rotate at any angle. The cutting assembly can move left and right on the X-axis moving assembly, move up and down in the Y-axis lifting assembly, and slide back and forth relative to the X-axis moving assembly. In other words, this invention can achieve multi-axis rotation and linear motion feed along the X, Y, and Z axes, completing the movement of the product at various positions and improving cutting accuracy.

[0020] Preferably, the Y-axis lifting assembly includes Y-axis ball screws 2 mounted on both sides of the frame 1. One end of the Y-axis ball screw 2 is connected to a Y-axis servo motor 3, and the other end is connected to a Y-axis ball screw support 4. A Y-axis linear guide 5 is provided on one side of the Y-axis ball screw 2, and a Y-axis slider 6 is provided on the Y-axis linear guide 5. A Y-axis screw nut 7 is provided on the Y-axis ball screw 2. The X-axis moving assembly includes an X-axis base 8, and a Y-axis slide plate 9 is connected to both ends of the X-axis base 8. The X-axis base 8 is mounted on the Y-axis slider 6 via the Y-axis slide plate 9 and connected to the Y-axis screw nut 7. The Y-axis ball screw 2 is driven to rotate by the Y-axis servo motor 3, thereby driving the Y-axis screw nut 7 to move up and down, and ultimately driving the X-axis base 8 to move up and down along the Y-axis linear guide 5. Furthermore, the Y-axis ball screw 2 is provided with an upper Y-axis stop 10 and a lower Y-axis stop 11, and the Y-axis screw nut 7 is located between the upper Y-axis stop 10 and the lower Y-axis stop 11 to limit the vertical movement of the X-axis base 8.

[0021] Furthermore, X-axis linear guides 12 are provided on both sides of the X-axis base 8, and an X-axis ball screw 13 is provided between the two X-axis linear guides 12.

This invention provides two rotary tables 26, allowing for the loading of two products at once, or loading products from both sides, saving overall processing time and improving processing efficiency.

[0025] A tool drive motor 29 is mounted on the Z-axis sliding seat 19. The output end of the tool drive motor 29 is equipped with a tool drive wheel. The tool drive wheel is connected to a tool timing wheel via a timing belt. The tool timing wheel is connected to a tool timing shaft 30. The end of the tool timing shaft 30 is equipped with a blade 31 for cutting out the sprue and runner. A drill cutter can also be set in front of the blade 31 for drilling or milling.

[0027] A chip conveyor 35 is provided on the side of the frame 1 to remove the waste chips generated during cutting, and a chip loading trolley 36 is provided at the outlet of the chip conveyor 35 to remove waste chips. The specific structure and operation of the chip conveyor 35 and the chip loading trolley 36 are common knowledge in the field and are not the content protected by this utility model, so they will not be described in detail here.

[0028] This utility model can be used for cutting and removing runners and channels in volutes or other similar products. It can also be used to complete drilling and milling. It can perform actions in various directions and is applicable to multiple products. By simply changing the tooling and program formula, the model can be changed and multiple processing tools can be used to complete cutting, drilling and milling. It has strong applicability.

[0029] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model.
