[0034] Specific embodiment one, please refer to Figures 1-13The application discloses a laser processing control system based on a wind turbine nacelle, which comprises a lifting control assembly 1, and a laser processing structure 2 is installed on the lifting control assembly 1; wherein the laser processing structure 2 comprises a concentric bearing assembly 3, a lifting guide assembly 4 and a laser processing mechanism 5; the concentric bearing assembly 3 is fixedly installed on the lifting control assembly 1, and the concentric bearing assembly 3 comprises concentrically arranged guide ring seats 301 and support ring seats 302; the lifting guide assembly 4 is fixedly installed on the support ring seats 302, and the lifting guide assembly 4 comprises two symmetrical vertical guide grooves 401; the laser processing mechanism 5 is composed of a horizontal guide assembly 6 and a laser hole cutting assembly 7, the horizontal guide assembly 6 is arranged between the guide ring seats 301 and the support ring seats 302, and the horizontal guide assembly 6 is slidably connected with the vertical guide grooves 401.

[0036] In some embodiments, as shown in Figure 2 and Figure 4 The lifting control assembly 1 comprises a lifting frame 101 which is fixedly installed on a movable frame 8 (the movable frame 8 can be installed on a vehicle body to improve the stability of the whole equipment), a circular through hole 102 coaxial with the guide ring seat 301 is formed in one side of the lifting frame 101, the guide ring seat 301 is connected with the lifting frame 101 through fasteners, a lifting control frame 104 is slidably arranged on a first guide rail 103 fixedly installed on the lifting frame 101, an output end of a lifting hydraulic cylinder 105 installed on the top of the lifting frame 101 is connected with the lifting control frame 104, the lifting control frame 104 is controlled to move up and down along the first guide rail 103 through the lifting hydraulic cylinder 105, thereby realizing the up-and-down movement of the two laser processing mechanisms 5, and the up-and-down movement range of the lifting control frame 104 is realized by parameter setting of the lifting hydraulic cylinder 105 on a control system.

[0037] In some embodiments, as shown in Figure 8 and Figure 9As shown, the guide ring seat 301 and the support ring seat 302 are connected through a plurality of fixed plates 303 arranged in a ring, the guide ring seat 301 is symmetrically provided with two arc-shaped channels 304 on the circumferential side, and the horizontal guide frame 601 penetrates and fits in the arc-shaped channels 304 and can slide along the inner wall thereof; the lifting guide assembly 4 further comprises a fixed ring seat 402 sleeved outside the support ring seat 302, the fixed ring seat 402 and the support ring seat 302 are connected through fasteners, and the fixed ring seat 402 is symmetrically fixed with two lifting guides 403 on the circumferential side, and the vertical guide groove 401 is arranged on the lifting guide 403.

[0038] In some embodiments, as shown in Figure 10 , Figure 11 The horizontal guide assembly 6 further comprises a moving frame 605 connected with the vertical guide groove 401 in a sliding manner, the horizontal guide platform 606 is installed on the moving frame 605 through fasteners, the second guide rail 607 and the axial extension plate 608 are respectively fixedly arranged on the horizontal guide platform 606, the horizontal guide platform 606 is provided with a horizontal channel 609 on the surface, the horizontal channel 609 is located between the two second guide rails 607, and the lifting control frame 104 and the two moving frames 605 below are connected through fasteners, so that the up-down movement of the two laser processing mechanisms 5 below can be realized through the up-down movement of the lifting control frame 104.

[0039] Further, the horizontal guide frame 601 is arranged in a sliding manner on the moving frame 605, the moving frame 605 is provided with a first elastic member 610 connected with the horizontal guide frame 601, the end of the axial support part 602 away from the horizontal guide platform 606 is fixedly provided with a first mounting seat 611, the first mounting seat 611 is installed with an air supplier 612 (a common air supply device in the prior art) on the side close to the horizontal guide platform 606, the air outlet of the air supplier 612 is connected with the air supply pipeline 604, and the guide wheel 603 rolls along the inner wall of the guide ring seat 301. The first elastic member 610 is always in a compressed state, and the elastic force of the first elastic member 610 ensures that the guide wheel 603 can only roll tightly against the inner wall of the guide ring seat 301.

[0040] In some embodiments, as shown in Figure 10 , Figure 12 and Figure 13As shown, the laser cutting section also includes a horizontally movable seat 703 slidably disposed between two second guide rails 607. A hollow air guide tube 704 is fixedly fixed through the horizontally movable seat 703 and fits inside the horizontal channel 609. During the sliding process of the horizontally movable seat 703 along the second guide rails 607, the hollow air guide tube 704 moves along the inside of the horizontal channel 609. One end of the hollow air guide tube 704 is fixed with a connecting sleeve 705 sleeved on the axial support part 602. The hollow air guide tube 704 is connected to the axial support 602 by fasteners, which ensures that the hollow air guide tube 704 always moves horizontally synchronously with the axial support 602. That is, during the horizontal movement of the horizontal guide frame 601, the axial support 602, which moves synchronously with the horizontal guide frame 601, drives the hollow air guide tube 704 to move horizontally synchronously, thereby driving the entire laser cutting assembly 7 to move horizontally along the horizontal guide platform 606. The hollow air guide tube 704 is connected to an air guide connector 706 that is connected to the air supply pipe 604.

[0041] Furthermore, a first pulley 707 is rotatably mounted on the hollow air duct 704, and a rotating work plate 701 is sleeved on the hollow air duct 704 and fixedly connected to the first pulley 707. The output shaft of the hole-cutting control motor 708 mounted on the horizontal moving seat 703 is connected to a second pulley 709. The first pulley 707 and the second pulley 709 are connected by a transmission belt 710. When the hole-cutting control motor 708 is started, the second pulley 709 is driven to rotate by the hole-cutting control motor 708. With the cooperation of the transmission belt 710 and the first pulley 707, the rotating work plate 701 is rotated synchronously, thereby realizing the circumferential movement of the laser hole cutter 702. In this process, the laser hole cutter 702 completes the hole-cutting process of the cabin cover 10 by rotating around once. The metal sheet after laser hole cutting stays in the mounting hole after the hole is cut.

[0042] When the laser processing equipment is moved to the designated position for laser cutting via the mobile frame 8 (i.e., the laser processing equipment moves close to the position of the hole to be cut on the housing 10), in this embodiment, the number of mounting holes for the required cutting on the housing 10 is set to ten. Initially, the two laser processing mechanisms 5 are in... Figure 6 At the position shown, the laser cutters 702 on both laser processing mechanisms 5 are located at the middle of the support ring seat 302. Then, the control system simultaneously starts the two cutting control motors 708 (simultaneously starting the laser cutters 702). Under the combined action of the first pulley 707, the second pulley 709 and the transmission belt 710, the rotating worktables 701 on both sides are rotated synchronously, so that the laser cutters 702 on both sides perform synchronous circumferential motion. In this process, the laser cutter 702 completes one circumferential motion (which can also be two circumferential motions depending on the specific cutting situation) to achieve the cutting of the cover 10.

[0043] After the laser hole cutting process of two installation holes is completed, the hole cutting control motor 708 and the laser hole cutter 702 are controlled to be turned off, and the two laser processing mechanisms 5 are controlled to move upward by a set distance through the lifting hydraulic cylinder 105 and the lifting control frame 104 (that is, the two laser hole cutters 702 move upward by a set distance at this time), in this process, the guide wheels 603 roll along the inner wall of the guide ring seat 301, and the two laser hole cutters 702 are moved to the set position under the elastic force of the first elastic member 610 (the horizontal moving seat 703 moves along the horizontal guide table 606 to the direction close to the shaft center of the support ring seat 302), then the laser hole cutter 702 is controlled to move circularly again through the hole cutting control motor 708, and the hole cutting process of the cabin cover 10 is realized through one circular movement of the laser hole cutter 702, when the laser hole cutting process of two installation holes is completed again, the hole cutting control motor 708 and the laser hole cutter 702 are controlled to be turned off, and the two laser processing mechanisms 5 are controlled to move upward by a set distance through the lifting hydraulic cylinder 105 and the lifting control frame 104, in this process, the guide wheels 603 roll along the inner wall of the guide ring seat 301, and the two laser hole cutters 702 are moved to the set position under the elastic force of the first elastic member 610 (the horizontal moving seat 703 moves along the horizontal guide table 606 to the direction close to the shaft center of the support ring seat 302), then the laser hole cutter 702 is controlled to move circularly again through the hole cutting control motor 708, and the hole cutting process of the cabin cover 10 is realized through one circular movement of the laser hole cutter 702.

[0044] When the laser cutting of the uppermost symmetrical two mounting holes is completed, the two laser processing mechanisms 5 are controlled to move downward to the initial position by the lifting hydraulic cylinder 105 and the lifting control frame 104, and then the two laser processing mechanisms 5 are controlled to move downward by a set distance (i.e. the two laser cutters 702 move downward by a set distance at this time) by the lifting hydraulic cylinder 105 and the lifting control frame 104. In this process, the guide wheels 603 roll along the inner wall of the guide ring seat 301, and the two laser cutters 702 move to the set position under the elastic force of the first elastic member 610 (the horizontal moving seat 703 moves along the horizontal guide table 606 to the direction close to the shaft center of the support ring seat 302), and then the laser cutter 702 is controlled to move circularly by the cutting control motor 708. The laser cutting of the cabin cover 10 is realized by one circular movement of the laser cutter 702. The laser processing of each mounting hole on the cabin cover 10 is realized in sequence according to the same cutting control mode in the process of moving upward of the laser processing mechanism 5. After the laser processing of each mounting hole arranged circularly at one side of the cabin cover 10 is completed, the two laser processing mechanisms 5 are controlled to move upward to the initial position by the lifting hydraulic cylinder 105 and the lifting control frame 104. At this time, the mounting holes that have completed the cutting process are arranged in a circular array at this position. Then, when the laser processing equipment is moved to the next specified position to be laser cut (i.e. the laser processing equipment is moved close to the position to be cut on the cabin cover 10), the laser cutting is realized according to the same control mode. The laser cutting of two mounting holes is realized at the same time according to the above method, which greatly improves the laser processing efficiency of the cabin cover 10.

[0045] In a second embodiment, based on the first embodiment, as Figure 12 and Figure 13As shown, the discharging power part includes a gas push piston 711 which is slidingly fitted inside the hollow air guide pipe 704, the gas push piston 711 is fixedly installed with a discharging push rod 712 on one side, and is fixedly installed with a reset connecting rod 713 on the other side, the reset connecting rod 713 is slidingly penetrated to the outside of the first mounting seat 611 and is fixed with a second mounting seat 714, and the second mounting seat 714 is provided with a second elastic member 715 between the first mounting seat 611; after the laser hole cutting processing of two mounting holes at a certain height position is completed, the control system starts the air supplier 612, air is transported into the hollow air guide pipe 704 through the air supplier 612, the air supply pipeline 604 and the air guide joint 706, the gas push piston 711 slides along the inner wall of the hollow air guide pipe 704 under the action of air pressure and approaches the rotary worktable 701, the reset connecting rod 713 which moves synchronously with the gas push piston 711 drives the second mounting seat 714 to move and compresses the second elastic member 715, the discharging push rod 712 which moves synchronously with the gas push piston 711 moves into the mounting hole to extrude the waste material after laser hole cutting, so that the waste material is separated from the mounting hole after hole cutting, that is, the complete processing of one mounting hole is completed, and the reverse movement and reset of the gas push piston 711 are realized under the action of the elastic restoring force of the second elastic member 715 after the air supplier 612 is closed. At this time, the discharging push rod 712 retracts into the hollow air guide pipe 704.

[0046] In some embodiments, as shown in Figure 1 、 Figure 2 and Figure 5 The present application also includes a hole cutting positioning assembly 9 installed between the two axial extension plates 608, as shown. The hole cutting positioning assembly 9 includes a hole cutting positioning ring seat 901 for positioning the cabin cover 10, two horizontal support members 902 are fixedly and symmetrically arranged on the side surface of the hole cutting positioning ring seat 901, the horizontal support members 902 are sleeved on the axial extension plates 608 and are connected through fasteners, the axial extension plates 608 are installed with a biasing air cylinder 903 connected with the horizontal support members 902 (specifically, the biasing air cylinder 903 is installed on the axial extension plates 608 through a connecting seat 904), when the laser processing equipment is moved by the moving frame 8 so that the hole cutting positioning ring seat 901 is sleeved on the cabin cover 10, at this time, the laser processing equipment is just moved to the specified position to be laser cut (that is, the laser processing equipment is moved close to the position to be cut on the cabin cover 10), thereby realizing the positioning of the entire laser processing equipment on the cabin cover 10, after the positioning is completed, the hole cutting positioning ring seat 901 is controlled to be separated from the cabin cover 10 through the retraction movement of the biasing air cylinder 903, and then the laser hole cutting processing of the cabin cover 10 can be started. Through the arrangement of the hole cutting positioning assembly 9, the precise positioning of the laser processing equipment on the cabin cover 10 is realized, which can effectively avoid the hole position deviation in the laser hole cutting process, thereby ensuring the precision of the laser hole cutting processing of the cabin cover 10.
