Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to laser cutting equipment for processing aircraft parts. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces. It is divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture. Due to the small laser spot, high energy density and fast cutting speed, laser cutting can achieve better cutting quality. Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC workbenches, and the entire cutting process can be fully CNC-controlled. During operation, you only need to change the CNC program to apply the cutting of parts of different shapes, which can perform both two-dimensional cutting and three-dimensional cutting.

[0003] Before laser cutting aircraft parts, the parts need to be clamped and centered. Since laser cutting has a high speed and high energy density, if the part to be cut is not accurately centered, the cut parts will be difficult to reuse. Therefore, we proposed a laser cutting device for processing aircraft parts. Summary of the invention

The upper inclined ring piece tilts upward and drives the top barb strip to scrape and comb the inner brush to prevent the inner brush from accumulating too much debris and dust that are difficult to remove after long-term use. The scraped dust and debris fall downward through the inclined circular holes of the upper inclined ring piece, preventing a large amount of dust and debris from accumulating on the upper inclined ring piece and affecting the upward inclination of the upper inclined ring piece. The built-in cone block facilitates the fallen dust and debris to slide outward, preventing a large amount of debris from accumulating on the plane at the top of the top cylinder and being difficult to discharge.

At the same time, the waveform connecting piece 207 moves to slide and scrape the bottom of the inner wall of the curved ring shell 201. At the same time, the waveform connecting piece 207 cooperates with the change of the aperture range when the arc block 206 moves through the waveform retractable performance. When the arc block 206 drives the waveform connecting piece 207 to extend, the waveform connecting piece 207 pushes the scraped debris to fall downward through the bottom arc hole 203 and be discharged.

[0029] For the second embodiment, please refer to Figure 6-Figure 9 The present invention provides a laser cutting device for processing aircraft parts: the inner cleaning device 8 comprises an expansion sleeve 801, the outer surface of the expansion sleeve 801 is provided with a bottom arc inclined hole 802, the top of the expansion sleeve 801 is fixedly connected with a top brush 803, the inner wall of the expansion sleeve 801 is fixedly connected with a corrugated arc sheet 804, the outer surface of the corrugated arc sheet 804 is provided with a corrugated arc hole 805, the expansion sleeve 801 is sleeved on the top cylinder 7 and fixedly connected to the top cylinder 7, four bottom arc inclined holes 802 are arranged and evenly distributed on the outer surface of the expansion sleeve 801, a plurality of top brushes 803 are arranged and evenly distributed on the top of the expansion sleeve 801, and four corrugated arc sheets 804 are arranged and evenly distributed on the inner wall of the expansion sleeve 801;

[0030] The stripping device 9 includes an inner inclined soft plate 901, an outer arc bottom hole 902 is provided on the outer surface of the inner inclined soft plate 901, a built-in cone block 903 is fixedly connected to the bottom of the inner wall of the inner inclined soft plate 901, an inner brush 904 is fixedly connected to the inner wall of the inner inclined soft plate 901, an upper inclined ring piece 905 is fixedly connected to the inner wall of the inner inclined soft plate 901, a top thorn bar 906 is fixedly connected to the top of the upper inclined ring piece 905, and an inclined circular hole 907 is provided on the outer surface of the upper inclined ring piece 905, the inner inclined soft plate 901 is sleeved on the top cylinder 7 and fixedly connected to the top cylinder 7, four outer arc bottom holes 902 are provided and evenly distributed on the outer surface of the inner inclined soft plate 901, a plurality of inner brushes 904 are provided and evenly distributed on the inner wall of the inner inclined soft plate 901, and a plurality of top thorn bars 906 are provided and evenly distributed. At the top of the upper inclined ring piece 905, there are multiple inclined circular holes 907 evenly distributed on the outer surface of the upper inclined ring piece 905. When in use, after the laser cutter 14 completes the circular cutting, the double-sided pull plates 5 are pulled to drive the top cylinder 7 to move to the bottom center position of the annular accessory 3 through the electric telescopic rod 6. At this time, the top cylinder 7 is pushed upward by the electric telescopic rod 6. When the top cylinder 7 moves, it drives the inner cleaning device 8 and the stripping device 9 to move upward together. The aperture of the top of the expansion sleeve 801 on the top cylinder 7 is slightly larger than the annular accessory 3. When the expansion sleeve 801 moves up to the bottom of the annular accessory 3, the inner surface begins to turn outward. At this time, the top brush 803 on the top of the expansion sleeve 801 rubs and cleans the inner wall of the annular accessory 3 as the expansion sleeve 801 moves, and the expansion sleeve 801 moves up to disengage. When the expansion sleeve 801 is inside the annular accessory 3, the electric telescopic rod 6 drives the top cylinder 7 to move downward, and the top cylinder 7 moves downward to drive the expansion sleeve 801 to move back to the inside of the annular accessory 3. When the expansion sleeve 801 moves down to the inside of the annular accessory 3, the top is always in contact with the inner wall of the annular accessory 3 and merges into an inverted cone. At this time, the debris cleaned up inside the expansion sleeve 801 falls downward and falls downward through the bottom arc inclined hole 802 and is discharged. When the expansion sleeve 801 is inside the annular accessory 3, the motor 10 is started to drive the expansion sleeve 801 to rotate through the top cylinder 7. When the expansion sleeve 801 rotates, the corrugated arc sheet 804 on the inner wall rotates accordingly and shrinks obliquely upward under the action of centrifugal force. When the corrugated arc sheet 804 shrinks, the inner wall of the expansion sleeve 801 is slid and scraped off. At the same time, the debris falling on the corrugated arc sheet 804 is discharged through the corrugated arc sheet 804. The arc hole 805 falls downward into the expansion sleeve 801, and the laser cutter 14 is moved to the center of the annular accessory 3. The electric telescopic rod 6 drives the top cylinder 7 to move, and the top cylinder 7 drives the top inner inclined soft plate 901 to move upward. When the inner inclined soft plate 901 moves up to contact with the laser cutter 14, it wraps the laser head of the laser cutter 14. When the inner inclined soft plate 901 continues to move upward, the inner wall is always in contact with the laser head and the dust and debris on the surface of the laser head are slid and peeled off. At the same time, the inner brush 904 on the inner wall of the inner inclined soft plate 901 rubs and cleans the surface of the laser head. When the inner inclined soft plate 901 moves downward and leaves the laser cutter 14, the upper inclined ring piece 905 on the inner wall tilts upward and drives the top thorn strip 906 to scrape and comb the inner brush 904.The scraped dust and debris fall downward through the inclined circular hole 907 on the upper inclined ring piece 905, and the built-in cone block 903 arranged at the bottom of the inner wall of the inner inclined soft plate 901 facilitates the fallen dust and debris to slide outward, and the slid dust falls outward through the outer arc bottom hole 902 and is discharged.

[0031] When the present invention is in operation, the electric telescopic rod 6 drives the top cylinder 7 to move down to the bottom of the curved ring shell 201, and then the double-side pull plates 5 are pulled to translate the top cylinder 7 to both sides of the curved ring shell 201, and the outer pull rod 205 is pulled outward to drive the arc surface block 206 to move together. At this time, the annular accessory 3 is placed inside the curved ring shell 201, and the bottom of the annular accessory 3 is flush with the bottom of the arc surface block 206. After the outer pull rod 205 is released, the pull-back spring 204 drives the outer pull rod 205 to move inward through the pull-back force, and the outer pull rod 205 drives the arc surface block 206 to clamp the annular accessory 3 inward, and the four arc surface blocks 206 are clamped and centered from all sides of the annular accessory 3. When the arc surface block 206 moves with the outer pull rod 205, it drives the corrugated connecting pieces 207 on both sides. The waveform connecting piece 207 moves simultaneously, and the bottom of the inner wall of the curved ring shell 201 is slidably scraped when the waveform connecting piece 207 moves. At the same time, the waveform connecting piece 207 cooperates with the change of the aperture range when the arc block 206 moves through the waveform retractable performance. When the arc block 206 drives the waveform connecting piece 207 to extend, the waveform connecting piece 207 pushes the scraped debris to fall downward through the bottom arc hole 203 and be discharged. The laser cutter 14 is moved to a suitable cutting position, and the motor 10 is started to drive the inner groove long plate 4 to rotate. The inner groove long plate 4 drives the curved ring shell 201 to rotate through the concave connecting plate 1. The rotation of the curved ring shell 201 drives the top wall cleaning mechanism 202 to rotate. At the same time, the curved ring shell 201 drives the annular accessory 3 to rotate through the arc block 206. When the laser cutter 14 is used to rotate the rotating annular accessory When the motor 10 is turned off and the curved ring shell 201 does not rotate, the corrugated expansion piece 2023 on one side of the top arc plate 2021 stretches inwards until it fits with the surface of the annular accessory 3. When the corrugated expansion piece 2023 stretches, the side arc pieces 2024 on both sides first rub against the annular accessory 3. The side arc pieces 2024 rub and scrape the surface of the annular accessory 3 from both sides of the corrugated expansion piece 2023 as the corrugated expansion piece 2023 stretches. When the motor 10 is started and the top arc plate 2021 is driven to rotate through the curved ring shell 201, the corrugated expansion piece 2023 rotates with the top arc plate 2021 and shrinks outwards under the action of centrifugal force. When the corrugated expansion piece 2023 is stretched and contracted, the outer surface of the corrugated expansion piece 2023 will contact and move with the corrugated swing bar 2022 on one side. The swing bar 2022 contacts and moves the corrugated sheet 2023 to remove the debris on the surface of the corrugated sheet 2023, and at the same time, the corrugated sheet 2023 is completely retracted toward the side of the top arc plate 2021. When the corrugated sheet 2023 is completely retracted, the rotatable corner block 2025 is rotated upward to contact the resistance of the rotating long rod 2027. At this time, the rotating long rod 2027 rotates toward the direction of the corrugated sheet 2023 and resists the retracted corrugated sheet 2023. After the laser cutter 14 completes the circular cutting, the double-sided pull plates 5 are pulled to drive the top cylinder 7 to move to the bottom center position of the annular accessory 3 through the electric telescopic rod 6. At this time, the top cylinder 7 is pushed upward by the electric telescopic rod 6. When the top cylinder 7 moves, it drives the inner cleaning device 8 and the stripping device 9 to move upward together.The aperture of the top of the expansion sleeve 801 on the top cylinder 7 is slightly larger than the annular accessory 3. When the expansion sleeve 801 moves up to the bottom of the annular accessory 3, the inner surface begins to turn outward. At this time, the top brush 803 on the top of the expansion sleeve 801 rubs and cleans the inner wall of the annular accessory 3 as the expansion sleeve 801 moves. When the expansion sleeve 801 moves up to be separated from the inside of the annular accessory 3, the electric telescopic rod 6 drives the top cylinder 7 to move down, and the top cylinder 7 moves down to drive the expansion sleeve 801 to move back to the inside of the annular accessory 3. The expansion sleeve 801 moves down to the inside of the annular accessory 3 When the expansion sleeve 801 is located inside the annular accessory 3, the top is always in contact with the inner wall of the annular accessory 3 and merges into an inverted cone. At this time, the debris cleaned up inside the expansion sleeve 801 falls downward and is discharged downward through the bottom arc inclined hole 802. When the expansion sleeve 801 is located inside the annular accessory 3, the start motor 10 drives the expansion sleeve 801 to rotate through the top cylinder 7. When the expansion sleeve 801 rotates, the corrugated arc sheet 804 on the inner wall rotates accordingly and contracts obliquely upward under the action of centrifugal force. When the corrugated arc sheet 804 contracts, it slides and scrapes the inner wall of the expansion sleeve 801, and at the same time falls on the corrugated arc sheet 80 The debris on the laser cutter 14 falls downward into the expansion sleeve 801 through the waveform arc hole 805, and the laser cutter 14 is moved to the center of the annular accessory 3. The electric telescopic rod 6 drives the top cylinder 7 to move, and the top cylinder 7 drives the top inner inclined soft plate 901 to move upward. When the inner inclined soft plate 901 moves up to contact with the laser cutter 14, it wraps the laser head of the laser cutter 14. When the inner inclined soft plate 901 continues to move upward, the inner wall of the inner inclined soft plate 901 is always in contact with the laser head and the dust and debris on the surface of the laser head are slid and peeled off. At the same time, the inner wall of the inner inclined soft plate 901 The inner brush 904 rubs and cleans the surface of the laser head. When the inner inclined soft board 901 moves downward and leaves the laser cutter 14, the upper inclined ring piece 905 on the inner wall tilts upward and drives the top thorn bar 906 on the top to scrape and comb the inner brush 904. The scraped dust and debris fall downward through the inclined circular hole 907 on the upper inclined ring piece 905. At the same time, the built-in cone block 903 set at the bottom of the inner wall of the inner inclined soft board 901 facilitates the fallen dust and debris to slide outward. The fallen dust falls outward through the outer arc bottom hole 902 and is discharged.
