[0002] With the gradual improvement of my country's ship design capabilities, the development of various ship types is showing a trend towards larger size and lighter weight, and ships are also adopting a large number of curved outer plates and irregular structural components in the design process. Therefore, the three-dimensional irregular high-precision cutting technology of curved metal plates is a core technology that the current shipbuilding industry urgently needs to overcome in the processing of curved outer plates and irregular structural components.

[0065] Example 2 This embodiment provides a cutting method that utilizes any of the cutting devices described in Embodiment 1 to achieve high-precision cutting of the target object.

[0066] Reference Figure 7 and Figure 8 The cutting method provided in this embodiment includes the following steps: S1. Fix the target object to be cut onto the support base and adjust the support platform to a horizontal position; S2. Use a scanner to scan the target object to obtain the shape information of the target object; S3. Based on the morphological information, generate time-displacement code using the console; S4. Adjust the position of the cutting mechanism, and cut the target object according to the time-displacement code.

[0067] First, step S1 is executed to adjust the height of the support column 321 on the bearing base 32, adjust the angle of the self-locking axial coupling support part 332 on the support column 321, and use the permanent magnet chuck 333 to complete the attachment and fixation of the target cutting object 7 on the bearing base 32. The first servo motor 213 is used to control the rotation of the first lead screw 211 to adjust the bearing platform 31 to a horizontal state.

[0068] The support column 321 can be a telescopic rod structure or other suitable height-adjustable structure for supporting the target cutting object 7. Preferably, the support column 321 is designed as a telescopic rod structure. Further, the number of support columns 321 can be 1, 2, 3, 4 or other suitable values ​​for stabilizing the target cutting object. Specifically, the specific number of support columns 321 can be set according to actual needs. Preferably, the number of support columns 321 is 4.

[0069] Next, step S2 is performed, using scanner 51 to scan the shape of the target cutting object 7 to obtain complete shape information of the target cutting object 7. Optionally, scanner 51 can be one or more of laser 3D scanners or other suitable scanners. Further, the number of scanners 51 is at least 2, and can be 2, 3, 4 or other suitable values. The specific number of scanners 51 can be set according to actual needs. Preferably, the number of scanners 51 is 2.

[0070] Next, step S3 is executed. Based on the three-dimensional shape information of the object 7 to be cut, the three-dimensional model is reconstructed, the coordinate origin is selected, and the cutting path is drawn using the console 52, and time-displacement code is generated. The console 52 is equipped with cutting software, which is used to realize the three-dimensional model reconstruction of the target object 7, the selection of the coordinate origin, and the drawing of the cutting path, and to generate time-displacement code. Furthermore, the cutting software can be one or more of SolidWorks, LightBurn, or other suitable cutting software in combination.

[0071] Specifically, based on the scanning results of step S2, the target object 7 is reconstructed using cutting software. A point on the model is selected as the origin O. Based on the origin, the cutting path (abcdefghija) is drawn on the model. Cutting points are collected along the cutting path according to the cutting accuracy requirements. The three-dimensional coordinate data of all collected points are calculated using the origin O as a reference. The cutting path trajectory and the time t to reach any collected point i are planned using the cutting software. i The cutting software splits the three-dimensional coordinates of the acquisition point into three directions: X, Y, and Z, corresponding to the first, second, and third directions, respectively, and generates the time coordinates (X, Y, and Z) of the cutting mechanism as it moves to any acquisition point i. i , t i ), (Y i , t i (Z) i , t i Subsequently, the cutting software calculates and generates the first servo motor 213, the second servo motor 223, and the third servo motor 233 based on the time coordinate value, according to time t. i Time-displacement code for motion.

[0072] Next, step S4 is executed, adjusting the position of the cutting mechanism 4 so that it is directly above the coordinate origin O, and zeroing the positions of the first servo motor 213, the second servo motor 223, and the third servo motor 233. The cutting mechanism 4 is used to cut the target object 7. Optionally, the cutting mechanism 4 can be a laser cutting machine, a plasma cutting machine, a waterjet cutting machine, or other suitable cutting mechanism. The first servo motor 213, the second servo motor 223, and the third servo motor 233 can be stepper servo motors, linear servo motors, or other suitable servo motors, used to convert electrical energy into mechanical energy and achieve high-precision motion control.

[0073] Next, based on the time-displacement code, the cutting mechanism 4, the first servo motor 213, the second servo motor 223 and the third servo motor 233 are controlled to reciprocate, so as to realize the three-dimensional path movement of the cutting mechanism 4 relative to the target cutting object 7, and finally complete the high-precision cutting of the target cutting object 7.

[0074] This method utilizes a cutting device to cut the target object 7. An adjustable-height support column 321 and a self-locking axial coupling 33 ensure the target object 7 is fixed and prevent deformation during the cutting process. A servo motor, acting as the power output source, along with a lead screw and gear mechanism, enables the cutting mechanism 4 to move along a three-dimensional path relative to the target object 7 during the cutting operation. This frees the cutting operation from the shape of the target object 7, effectively improving the cutting accuracy in three-dimensional irregular cutting operations.
