[0001] This invention belongs to the field of laser welding technology, specifically relating to a cutting machine for processing civil aircraft parts. Background Technology

[0002] Civil aircraft components include high-precision parts such as wings, fuselages, turbofan engines, and blades. These components use a large amount of sheet metal during processing. The sheet metal is processed by cutting, shaving, drilling, and stamping to achieve the required size and shape so that it can be assembled into the required civil aircraft components.

[0003] In the laser cutting process, the sheet material needs to be placed on the cutting table manually before laser cutting, and the cut sheet material needs to be removed from the cutting table manually after laser cutting. This is not only labor-intensive but also inefficient, thus reducing the processing efficiency.

[0004] Therefore, a cutting machine for processing civil aircraft parts is proposed. Summary of the Invention

[0024] 4. In this invention, when the silicone disc approaches the board, the sweeping plate first touches the top of the board, and before the silicone disc touches the board, the bottom area of ​​the silicone disc is swept and cleaned. This ensures that the silicone disc automatically sweeps the designated area before touching the board, thus ensuring the firmness of the silicone disc's fastening to the board and preventing debris from interfering with the firmness of the fastening between the silicone disc and the board.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Reference Figure 1-7 A cutting machine for processing civil aircraft parts includes a laser cutting table 1, a gantry frame 3, and a gantry frame 4. Two guide rails 2 are symmetrically installed on the outer side of the laser cutting table 1. The gantry frame 3 and the gantry frame 4 are installed above the two guide rails 2. The gantry frame 3 is located on one side of the gantry frame 4. Motors 4 5 are installed on the outer surface of one side of both the gantry frame 3 and the gantry frame 4. Studs 3 6 are installed at the drive ends of both motors 4 5. Displacement nuts are installed on the stud nuts of both studs 3 6. The bottom of the two displacement tables 7 are respectively equipped with laser cutting heads 8 and parts loading and unloading components 9. Motor frames 10 are installed on the outer surfaces of gantry frame 1 3 and gantry frame 2 4. Motor 5 11 is installed on one side of the outer surface of motor frame 10. Drive disk 12 is installed at the drive end of motor 5 11. The outer circumference of drive disk 12 is provided with teeth 3. The top of the two guide rails 2 is provided with teeth 4. Teeth 3 and teeth 4 are engaged. Traveling wheels 14 rotate on the outer surfaces of gantry frame 1 3 and gantry frame 2 4.

[0040] When loading, unloading, and laser cutting sheet metal for aircraft parts, the first gantry 3 and the second gantry 4 are controlled to move linearly along the guide rail 2. The drive end of the fifth motor 11 is controlled to pull the drive disk 12 to rotate. The engagement between the drive disk 12 and the rail plate 13, and the rotational movement of the traveling wheels 14, cause the first gantry 3 and the second gantry 4 to move. The part loading and unloading component 9 on the first gantry 3 places the sheet metal onto the laser cutting table 1, and the laser cutting head 8 on the second gantry 4 laser cuts the sheet metal on the laser cutting table 1. After cutting, the position of the second gantry 4 changes to make room, and the part loading and unloading component 9 on the first gantry 3 removes the sheet metal, thus realizing the laser cutting and loading / unloading of sheet metal for large-volume parts.

[0041] The parts loading / unloading component 9 includes an articulated robot 91, a support frame 92, and several funnel-shaped silicone discs 93. The top of the articulated robot 91 is fixedly connected to the bottom of another displacement stage 7. An air pump 95 is installed in the support frame 92. One side of the air pump 95 is connected to several connecting channels 96, which are fixedly connected to the silicone discs 93. It also includes:

[0042] The orientation control component includes several guide frames 94 movable in the support frame 92 and an adjustable unit for moving the guide frames 94. A silicone disc 93 is installed under the guide frame 94. The adjustable unit includes a stud 97 screwed into the support frame 92 and a motor 98 installed in the support frame 92. The drive end of the motor 98 is fixedly connected to one side of the stud 97. The screw on the stud 97 is connected to a variable seat 99, which is installed in the guide frame 94.

[0043] During the feeding process, when adjusting the orientation of each silicone disc 93 according to the specifications of the sheet material, the motor 98 pulls the stud 97 to rotate clockwise, causing the movable seat 99 to move outwards towards the articulated robot 91, thereby pulling the guide frame 94 and the silicone disc 93 to move together. When the motor 98 pulls the stud 97 to rotate counterclockwise, the movable seat 99 moves inwards towards the articulated robot 91, thereby pulling the guide frame 94 and the silicone disc 93 to move together, thus achieving the function of motorized adjustment of the orientation of the silicone disc 93.

[0044] The detection component is installed between the guide frame 94 and the silicone disc 93 to detect the load at the lower end of the silicone disc 93. The detection component includes a connecting seat 910 installed at the lower end of the guide frame 94 and a sensing element 911 installed at the lower end of the connecting seat 910. The sensing element 911 is a BF350 high-precision resistance strain gauge. The lower end of the sensing element 911 is fixedly connected to the upper end of the silicone disc 93.

[0045] After the silicone disc 93 is fastened to the column plate, when the articulated robot 91 pulls the load-bearing frame 92 upward, the connecting seat 910 and the sensing element 911 pull the silicone disc 93 and the plate at the lower end together. At this time, the sensing element 911 at the upper end of each silicone disc 93 can detect the load borne by the lower end of the corresponding silicone disc 93, and at the same time transmit the detection information to the processor. The processor controls the balance point to adjust the movement of the component.

[0046] A balance point adjustment component is installed between the articulated robot 91 and the support frame 92. When the silicone disc 93 is fastening the plate, it adjusts the balance point of the support frame 92 based on the load detected by the detection component. The balance point adjustment component includes a support cover 912 installed at the lower end of the articulated robot 91 and a rotating seat 913 screwed onto the upper end of the support cover 912. A guide opening 914 is provided in the rotating seat 913, and a movable seat 915 is movably installed in the guide opening 914. A rotating frustum 91 is screwed into the support cover 912. 6. The lower end of the rotating frustum 916 has a guide opening 917, and the upper end of the movable seat 915 can move in the guide opening 917. The inner surface of the upper end of the support cover 912 is equipped with a motor 918, and the drive end of the motor 918 is fixedly connected to the center of the upper end of the rotating frustum 916. The lower end of the rotating frustum 916 is screwed to a stud 919, and a motor 920 is also installed at the lower end of the rotating frustum 916. The drive end of the motor 920 is fixedly connected to one side of the stud 919, and the movable seat 915 is also threaded to the stud 919.

[0047] When it is detected that the load on the lower end of one of the silicone discs 93 is too high, the second motor 918 pulls the rotating platform 916 to rotate. The rotating platform 916 pulls the movable seat 915 and the rotating seat 913 to rotate together, so that the silicone disc 93 and the movable seat 915 are collinear. That is, when the movable seat 915 moves, it moves toward the silicone disc 93. The third motor 920 pulls the second stud 919 to rotate, pulling the movable seat 915 to move toward the silicone disc 93 along the inner surface of the guide port 914 and the guide port 917. This achieves the purpose of adjusting the load application point of the board, making the load on each silicone disc 93 more uniform, and preventing one silicone disc 93 from being overloaded and separating from the board. In this process, controlling the movement of the movable seat 915 cannot ensure that the load on each silicone disc 93 is exactly the same, but only reduces the difference in load between each silicone disc 93, and improves the reliability of board transfer.

[0048] The support cover 912 is surrounded by constraint rods 921. The upper end of the support frame 92 has two pairs of constraint openings 922, and the constraint rods 921 are embedded in the constraint openings 922.

[0049] The purpose of the constraint rod 921 being embedded in the constraint opening 922 is to prevent the bearing frame 92 and the lower plate from moving together when the traction movable seat 915 moves. When the rotating frustum 916 and the rotating seat 913 rotate, the bearing frame 92 and the lower plate cannot move together, so that the movable seat 915 can be adjusted independently. The constraint rod 921 being embedded in the constraint opening 922 cannot produce the effect of supporting the bearing frame 92.

[0050] The board material sweeping component, mounted on the guide frame 94, automatically sweeps dust from the upper part of the board before the silicone disc 93 touches it. The board material sweeping component includes an adjustable rod 923 screwed into the guide frame 94, a sweeping plate 924 mounted on the lower end of the adjustable rod 923, and a transmission plate 925 movable on the upper end of the guide frame 94. A first tooth is pre-drilled on the outer surface of the transmission plate 925. A transmission frustum 926 is mounted on the outer surface of the adjustable rod 923, and a second tooth is pre-drilled on the outer circumference of the transmission frustum 926. The first and second teeth mesh. A skewed opening 927 and a through hole 928 are pre-drilled in the transmission plate 925. 28 are connected to each other; a connecting round plate is installed at one end of the sweeping plate 924, the upper end of the connecting round plate is fixedly connected to the lower end of the adjustable rod 923, a circular notch is reserved on the outer surface of the connecting round plate, a boss is movable in the circular notch, a traction square rod 929 is installed at the upper end of the boss, the top edge of the sweeping plate 924 is lower than the bottom edge of the boss, so the sweeping plate 924 cannot generate dynamic interference with the boss when it rotates, the upper end of the traction square rod 929 is in close contact with the inner surface of the skewed opening 927, a movable platform 930 is installed on one side of the transmission plate 925, a positioning platform 931 is installed on the outer surface of the guide frame 94, and an elastic element 932 is installed between the movable platform 930 and the positioning platform 931;

[0051] The articulated robot 91 pulls the support frame 92, guide frame 94, and silicone disc 93 close to the plate. The sweeping plate 924 first touches the upper end of the plate. When the guide frame 94 continues to approach, the sweeping plate 924 stops moving, and the adjustable rod 923 slowly shortens. Using the pressure effect of the traction square rod 929 and the skewed opening 927, the traction transmission plate 925 moves outward from the articulated robot 91. Using the meshing of the teeth between the transmission plate 925 and the transmission frustum 926, the adjustable rod 923 rotates half a turn, and then the sweeping plate 924 rotates around the adjustable rod 923. During the half-turn, the sweeping plate 924 cleans the area on the bottom side of the silicone disc 93 to prevent debris from interfering with the firmness of the fastening between the silicone disc 93 and the board. After the adjustable rod 923 rotates half a turn, the teeth between the transmission plate 925 and the transmission platform 926 disengage. After the adjustable rod 923 and the sweeping plate 924 stop rotating, the upper end of the board presses against the silicone disc 93. This achieves the purpose of automatically sweeping the designated position of the contact area before the silicone disc 93 and the board touch, ensuring the firmness of the fastening between the silicone disc 93 and the board.

[0052] After the silicone disc 93 is returned to its original position, the adjustable rod 923 is pulled by the sweeping plate 924 and extends on its own. The traction rod 929 descends together, and the transmission plate 925 is pulled back to its original position by the deformation restoring force of the elastic element 932.

[0053] Working principle:

[0054] During the loading process, when adjusting the orientation of each silicone disc 93 according to the specifications of the sheet material, the motor 98 pulls the stud 97 clockwise, causing the movable seat 99 to move outwards towards the articulated robot 91, thereby pulling the guide frame 94 and the silicone disc 93 together. When the motor 98 pulls the stud 97 counterclockwise, the movable seat 99 moves inwards towards the articulated robot 91, thereby pulling the guide frame 94 and the silicone disc 93 together, thus achieving the function of motorized control of the orientation of the silicone disc 93. After the control is completed, the articulated robot 91 pulls the bearing frame 92, guide frame 94 and silicone disc 93 close to the sheet material. The sweeping plate 924 first touches the upper end of the sheet material. When the guide frame 94 continues to approach, the sweeping plate 924 stops moving. As the adjustable rod 923 slowly shortens, the traction square rod 929 and the skewed opening 927 exert pressure, causing the traction transmission plate 925 to move outwards from the articulated robot 91. Utilizing the meshing of the teeth between the transmission plate 925 and the transmission frustum 926, the adjustable rod 923 rotates half a turn. Subsequently, the sweeping plate 924 rotates half a turn around the adjustable rod 923. During this period, the sweeping plate 924 cleans the area under the silicone disc 93, preventing debris from interfering with the firmness of the bond between the silicone disc 93 and the board. After the adjustable rod 923 rotates half a turn, the meshing of the teeth between the transmission plate 925 and the transmission frustum 926 disengages. After the adjustable rod 923 and the sweeping plate 924 stop rotating, the upper end of the board presses firmly against the silicone disc 93, thus achieving the desired effect. 3. Before contacting the board, the silicone disc 93 is automatically scanned at a designated location within the contact area to ensure its secure fastening to the board. After the silicone disc 93 is placed on the upper end of the board, the air pump 95 and the connecting channel 96 are used to secure the silicone disc 93 to the board. After the silicone disc 93 is secured to the board, when the articulated robot 91 pulls the carrier frame 92 upward, the connecting seat 910 and the sensing element 911 pull the silicone disc 93 and the lower end of the board together. At this moment, the sensing element 911 on the upper end of each silicone disc 93 can detect the load borne by the corresponding lower end of the silicone disc 93, and transmit the detection information to the processor. The processor controls the balance point to adjust the movement of the components, and the motor 2 918 pulls the rotating platform 916. The rotating disc 916 pulls the movable seat 915 and the rotating base 913 to rotate together, so that the silicone disc 93 and the movable base 915 are collinear. That is, when the movable base 915 moves, it moves towards the silicone disc 93. The motor 3 920 pulls the stud 2 919 to rotate, pulling the movable base 915 along the inner surface of the guide port 1 914 and guide port 2 917 towards the silicone disc 93. This achieves the purpose of adjusting the load application point of the board, making the load on each silicone disc 93 more uniform, and preventing one silicone disc 93 from being overloaded and separating from the board. In the process of controlling the movement of the movable base 915, it is impossible to ensure that the load on each silicone disc 93 is exactly the same, but only to reduce the difference in load between each silicone disc 93.Enhance the reliability of sheet metal transfer.
