Description

Technical Field

[0001] This utility model relates to a cutting machine for cutting automotive chassis parts or similar products, and in particular to a five-axis double-head cutting saw, belonging to the technical field of casting equipment. Background Technology

[0002] A cutting machine is a highly specialized CNC machine tool suitable for cutting materials with complex shapes and high precision requirements. Traditional two-dimensional or three-axis cutting machines can only operate in a plane. For workpieces with complex geometries, multiple clamping and positioning operations are often required, which not only increases processing time and cost but may also lead to cumulative errors. Furthermore, the design of a single cutting head limits production efficiency, especially when handling large batches or large workpieces; a single cutting head cannot meet the needs of rapid production. Especially with increasing market competition, companies urgently need to improve production efficiency to shorten time-to-market. This means not only needing to increase cutting speed but also reducing non-productive time (such as tool changes and parameter adjustments). Traditional cutting machines struggle to meet these high standards, especially when dealing with curved surfaces or complex structures.

[0003] Therefore, whether it's the need to improve processing precision or increase production efficiency, cutting equipment needs to possess good flexibility and wide adaptability. This invention arises from this need. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] like Figure 1-10As shown, the five-axis dual-head cutting machine of this utility model includes a base assembly, on which a gantry assembly, a moving assembly, a workpiece mounting assembly, a left tool changer assembly, and a right tool changer assembly are mounted. The cutting assembly is mounted on the gantry assembly, and the left and right tool changer assemblies are located on both sides of the workpiece mounting assembly for changing the tools on the cutting assembly.

[0033] The assembly includes two moving components, which are installed parallel to each other within the base assembly. Each moving component includes a moving lead screw 2 connected to a lead screw drive motor 1, a moving lead screw nut 3 on the moving lead screw 2, and moving slide rails 4 on both sides of the moving lead screw 2. The workpiece mounting assembly includes a sliding base plate 5, with both ends of the sliding base plate 5 mounted on the moving slide rails 4 and connected to the moving lead screw nut 3. When the lead screw drive motor 1 drives the moving lead screw 2 to rotate, the moving lead screw nut 3 moves on the moving lead screw 2, thereby driving the sliding base plate 5 to move along the moving slide rails 4, ultimately moving the entire workpiece mounting assembly within the base assembly.

[0034] Furthermore, the workpiece mounting assembly in this invention can also rotate and rock at multiple angles. This invention has a rocking component 7 connected to a rocking motor 6 on the sliding base plate 5. The rocking component 7 rocks back and forth under the drive of the rocking motor 6. A workpiece mounting platform 8 is provided above the rocking component 7. The workpiece mounting platform 8 is connected to a platform drive motor 9. The workpiece mounting platform 8 rotates under the drive of the platform drive motor 9 and can rotate to any position according to actual cutting needs.

[0035] Furthermore, in addition to the workpiece mounting assembly being movable, rotating, and rocking, the cutting assembly in this invention can be raised and lowered and moved left and right to further adjust the cutting angle. For this purpose, the gantry assembly in this invention is located behind the workpiece mounting assembly, including an X-axis base plate 11 connected between two columns 10. A Y-axis ball screw 12 is mounted on the column 10, and Y-axis linear guide rails 13 are provided on both sides of the Y-axis ball screw 12. Y-axis sliding blocks 14 are provided at both ends of the X-axis base plate 11. The Y-axis sliding blocks 14 are mounted on the Y-axis linear guide rails 13 and connected to the Y-axis linear guide rails 13 via Y-axis ball screw nuts (connected to the back of the Y-axis sliding blocks 14, not shown in the accompanying drawings). Driven by the Y-axis drive motor 15, they rise and fall along the Y-axis linear guide rails 13 and are limited by Y-axis limit blocks 16. An X-axis ball screw 17 is mounted on the X-axis base plate 11, and X-axis linear guide rails 18 are provided on both sides of the X-axis ball screw 17. The cutting assembly includes a cutting moving seat 19, which is mounted on the X-axis linear guide rail 18 via an X-axis sliding block 22 and connected to the X-axis ball screw nut 20. Driven by the X-axis drive motor 60, it slides along the X-axis linear guide rail 18 and is limited by the X-axis limiting block 21. Thus, the entire cutting assembly can move up and down and slide left and right.

[0036] In addition to the vertical lifting and horizontal movement of the cutting assembly and the rocking and rotating of the tooling mounting assembly, this invention also features a lifting function within the cutting assembly itself. The cutting assembly includes a horizontal cutter drive assembly and a vertical cutter drive assembly. The vertical cutter drive assembly is mounted on the vertical drive assembly, which includes a vertical drive motor 23. A vertical ball screw 24 is located at the output end of the vertical drive motor 23. Vertical linear guides 59 are located on both sides of the vertical ball screw 24, and a vertical slider 26 is mounted on each of the vertical linear guides 59. A vertical ball screw nut 25 is mounted on the vertical ball screw 24. The vertical cutter drive assembly is connected to the vertical ball screw nut 25 via the vertical slider 26 and, driven by the vertical drive motor 23, moves up and down along the vertical ball screw 24 following the vertical slider 26. Therefore, this invention has a five-axis adjustment function.

The drive wheel 31 is connected to a drive motor 32. The longitudinal cutting tool drive assembly has a longitudinal cutting tool mounting port 33 located at its lower end, and the cutting tool is changed via a right cutting tool changer assembly. Furthermore, the longitudinal driving motor 34 directly drives the longitudinal blade drive shaft 35 disposed internally within the longitudinal cutting tool drive assembly.

[0038] The left tool changer assembly and the right tool changer assembly are located on both sides of the workpiece mounting assembly. The left tool changer assembly includes a left tool changer guide rail 36, a left tool changer base 38 driven by a left tool changer cylinder 37 is provided on the left tool changer guide rail 36, a left tool changer cylinder connecting seat 39 is provided on the left tool changer base 38, and a left tool changer quick connector 40 is provided on the left tool changer connecting seat 39.

The end of the left tool handle 42 is provided with a left pull pin 44. The position of the left pull pin 44 is opposite to the transverse tool mounting port 27. When changing tools, the left tool handle 42 on the left tool holder 41 of different heights is selected according to the cutting position. The positioning is achieved by moving the left tool changer assembly. The tool change is achieved by the left pull pin 44 entering the transverse tool mounting port 27 in the transverse blade drive assembly.

[0039] The right tool changer assembly includes a right tool changer guide rail 45, on which a right tool changer base 47 driven by a right tool changer cylinder 46 is mounted. The right tool changer base 47 has a right tool changer cylinder connector 48, which is equipped with a right tool changer quick-connect plug 49 connected to the output shaft of the right tool changer cylinder 46. The right tool changer base 47 has several right tool holders 50 arranged from left to right. Each right tool holder 50 has a right tool shank 52 with a right-side blade 51. The end of the right tool shank 52 has a right-side pull stud 53, positioned opposite the longitudinal tool mounting opening 33. During tool changing, positioning is achieved by moving the right tool changer assembly and raising / lowering the longitudinal tool drive assembly. Tool changing is accomplished by the right pull stud 53 entering the longitudinal tool mounting opening 33 in the longitudinal blade drive assembly.

[0040] Furthermore, both the left tool-changing cylinder 37 and the right tool-changing cylinder 46 in this invention are equipped with exhaust throttle valves 54. Additionally, cable carriers 55 are provided in the X-axis movement and Y-axis lifting components of the gantry assembly, as well as in the self-lifting components of the cutting assembly, to facilitate cable routing.

[0041] This utility model is mainly used for cutting automotive chassis parts or similar products. Through a combination of five-axis motion and a double-headed cutter, it allows for the replacement of saw blades, milling cutters, and drill bits of different diameters to meet different work requirements and improve cutting accuracy. The base assembly also includes a protective plate 56 for dust prevention, and a chip conveyor 57 and an operation box 58 are provided on the side of the base assembly for controlling the utility model and removing dust. The specific structure and operation of the chip conveyor 57 and the operation box 58 are common knowledge in the field and are not the content to be protected by this utility model; therefore, they will not be described in detail here.

[0042] 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. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
