When producing automotive interior special-shaped parts, in order to ensure the accuracy of the interior edge, a laser cutting device is required. Compared with traditional cutting devices, the laser cutting device has the advantages of high flexibility and high precision. However, there are still some deficiencies in the existing laser cutting devices during use.

[0003] For example, the invention patent with the publication number CN106378537B discloses a laser cutting machine and a processing method for processing automotive interior parts, including: a machine base, a support frame, an upper moving device, a cutting robot, a laser cutting enclosure device, a fixing device, a camera device, and an electric control device; the support frame is installed on the machine base, the upper moving device is supported by the support frame and arranged above the machine base, the upper moving device includes a gear-rack transmission system driven by a stepping motor, the upper end of the cutting robot is connected to the lower end of the upper moving device, the fixing device is arranged on the machine base and close to the laser cutting enclosure device, the camera device is arranged at the entrance of the cutting machine and above the support frame, and the electric control device is arranged outside the support frame. The laser cutting machine for processing automotive interior parts increases the cutting range, is provided with a laser cutting enclosure device and a cutting fixture fixing device, reduces the impact on the surrounding environment, reduces the cutting fixture fixing time, and improves the production efficiency.

[0004] Although the above device can achieve the function of special-shaped cutting, during use, it cannot shield the side of the special-shaped part when changing to horizontal cutting. Especially for automotive interior special-shaped parts such as a housing, when laser cutting such interior parts, cutting cannot be carried out while protecting the side of the interior part. This results in that when cutting one side of the interior part, the opposite side of the cutting surface will also be affected by the cutting. Moreover, the existing cutting machine cannot adaptively adjust the cutting angle or keep the cutting angle unchanged when moving along an arc-shaped cutting trajectory, and cannot adjust the angle between the laser and the surface of the special-shaped part during cutting according to the structure of the special-shaped part, thus affecting the cutting effect. Summary of the Invention

[0015] Preferably, the lower half of the baffle is inclined. The center of the ball of the ball shaft is located inside the baffle. The ball shaft is adapted to drive the baffle to rotate on the mounting plate when the screw rod is screwed into the adjusting block.

[0016] Compared with the related art, the present invention has the following beneficial effects:

[0017] 1. Through the setting of the protection component, the baffle on the protection component is used to block the laser transmitted after cutting one side of the interior trim, thereby preventing it from affecting the other side of the interior trim. And because the baffle is inclined, the transmitted laser will only be reflected onto the adjustment plate even if it is reflected, avoiding the influence of the device on the other side and the bottom surface of the interior trim when laser cutting the side of the interior trim, ensuring the laser cutting quality of the device, solving the problem that the existing laser cutting device cannot block the side of the special-shaped part when changing to horizontal cutting, and being applicable to the laser cutting work of the special-shaped interior trim of the cover structure, ensuring that when the device cuts one side of the interior trim, the side opposite to the cutting surface is not affected by the transmitted laser.

[0018] 2. Through the setting of the support component, when the fourth motor drives the rotation of the rotating shaft on the support component, the guide plate on the extension plate abuts against the sliding rod, and the sliding rods around the connecting frame will gather towards the middle, so that the protection components at various positions gather towards the middle, and the positions of the baffles at various places can be adjusted according to the cutting position, ensuring that the transmitted laser will not shoot to the other side of the interior trim, and ensuring the stability and cutting quality of the device during operation.

[0019] 3. Through the setting of the angle switching component, the first connecting rod, the second electric push rod and the guiding component, when the first connecting rod is located outside the docking hole, no matter how the outer bushing on the device slides, the laser cutter under the outer bushing always points to the circular position of the second rotating ring. When the first connecting rod abuts against the connecting block and pushes the rectangular part on the connecting block into the inner groove, when the outer bushing moves, the outer wall of the first connecting rod always abuts against the inner wall of the docking hole, so that the outer shell and the laser cutter below it always point directly downward, and the outer shell will rotate relative to the connecting plate. By the outer shell abutting against the frustum of the connecting block, the connecting block does not affect the normal rotation of the outer shell, and then the connecting block can be automatically reset under the action of the spring force, so as to switch the laser cutting angle according to the structure of the interior trim, solving the problem that the existing laser cutting device cannot adaptively adjust the cutting angle or keep the cutting angle unchanged when moving along the arc cutting trajectory. This device can adjust the included angle between the laser and the surface of the interior trim during cutting according to the structure of the special-shaped interior trim, and has the advantage of stronger adaptability.

[0020] 4. Through the setting of the rotatable connecting shell and the first rotating ring that can rotate in the connecting shell, the device can adjust the cutting trajectory, can not only perform circumferential cutting, but also perform arc cutting. Cooperating with the slidable outer bushing on the second rotating ring, the device can adjust the cutting radius during circumferential cutting, enhancing the cutting effect of the device.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-12, a special-shaped cutting machine for laser automotive interior parts, including a base 1, a support plate 2 is fixedly installed on the base 1, a support block 3 is fixedly connected to the support plate 2, a first motor 4 is installed on the support block 3, a connecting shaft 5 is connected to the output shaft of the first motor 4, a connecting shell 6 is fixedly connected to the connecting shaft 5. By driving the connecting shaft 5 to rotate through the first motor 4, the connecting shell 6 can be rotated. A second motor 7 is installed at the bottom of the connecting shell 6, a first transmission wheel 8 is connected to the output shaft of the second motor 7, a first rotating ring 9 is installed on the side of the first transmission wheel 8, and the first rotating ring 9 is rotatably connected to the connecting shell 6. The second motor 7 is used to drive the first transmission wheel 8 to rotate, so as to drive the first rotating ring 9 to rotate around its own central axis, so as to adjust the position of laser cutting subsequently. A first fixing plate 10 is fixedly connected to the first rotating ring 9, an outer bushing 12 is slidably installed on the first fixing plate 10, a folding plate 13 is installed on the outer bushing 12, a third motor 14 is installed on the folding plate 13, a second transmission wheel 16 is connected to the output shaft of the third motor 14, a second rotating ring 11 is arranged below the second transmission wheel 16, and the first fixing plate 10 is fixedly connected to the second rotating ring 11. By driving the second transmission wheel 16 to rotate through the third motor 14, the second transmission wheel 16 will drive the third motor 14 and the outer bushing 12 to slide on the first fixing plate 10 through the second rotating ring 11, so that the device can change from longitudinally cutting the upper surface of the interior part to horizontally cutting the side surface of the interior part. A first electric push rod 18 is installed below the outer bushing 12, an angle switching component 19 is arranged below the first electric push rod 18, a laser cutter 20 is installed at the bottom of the angle switching component 19, first connecting rods 21 are arranged on both sides of the angle switching component 19, a guiding component 23 is rotatably connected to the outside of the connecting shell 6, a second electric push rod 22 is installed on the guiding component 23, and the second electric push rod 22 is connected to the first connecting rod 21. When laser cutting the interior part, the cutting angle can be adjusted as needed. When it is necessary to always maintain vertical cutting, the first connecting rod 21 can be installed into the angle switching component 19, and the guiding component 23 can keep the second electric push rod 22 moving up and down without rotating, so that the laser cutter 20 always remains in a vertical state. The first connecting rod 21 can also be removed from the angle switching component 19. At this time, when the laser cutter 20 slides on the first fixing plate 10 along with the outer bushing 12, the laser cutter 20 always points to the center of the device, so as to perform laser cutting work on the interior part with an arc structure. A third electric push rod 24 is installed in the middle of the base 1, a fourth motor 25 is fixedly arranged at the top of the third electric push rod 24, a fixing frame 26 is installed on the third electric push rod 24, support columns 30 are fixedly arranged around the fixing frame 26, a connecting frame 27 is connected to the top of the support columns 30, support components 28 are installed around the connecting frame 27, and a protective component 29 is installed on the support components 28.When the device performs side laser cutting on the interior trim of the housing structure, the interior trim can be supported by the support assembly 28, and then the protective assembly 29 is used to block the laser transmitted to the other side of the cutting surface. Moreover, the blocking position of the transmitted laser at each location can be synchronously adjusted through the support assembly 28 to prevent the transmitted laser from affecting the interior trim and ensure the laser cutting effect of the device.

[0038] Please refer to Figure 1 , the support plate 2 and the support block 3 are symmetrically distributed on the left and right sides of the connection shell 6. The base 1, the support plate 2 and the support block 3 are fixedly connected into an integral structure. The connection shell 6 is rotatably connected to the support block 3 on the right side of the base 1, ensuring stable support on both the left and right sides of the connection shell 6 and enhancing the overall stability of the device. The connection shell 6 can rotate on the support block 3 to change the initial cutting position.

[0039] Please refer to Figure 5 and Figure 6 , the outer surfaces of the first transmission wheel 8, the first rotating ring 9, the second rotating ring 11 and the second transmission wheel 16 are all provided with convex stripes. The first rotating ring 9 forms a first rotating structure with the connection shell 6 through the first transmission wheel 8. For the first rotating structure on the device, the first rotating ring 9 can rotate inside the connection shell 6, enabling the device to perform circumferential cutting work at specific positions of the shaped part. The outer bushing 12 forms a sliding structure with the first fixing plate 10 through the second transmission wheel 16 and the second rotating ring 11. Through the sliding structure on the device, the cutting range is changed during circumferential cutting, thereby meeting different cutting requirements for use.

[0040] Please refer to Figures 5-8 , the inner wall of the outer bushing 12 is mutually attached to the outer wall of the first fixing plate 10, enabling the outer bushing 12 to slide smoothly on the first fixing plate 10 and ensuring the stability of the device during cutting. A communication groove 17 for the second transmission wheel 16 to pass through is opened on the outer bushing 12. A second fixing plate 15 is fixedly connected to the outer bushing 12. The second transmission wheel 16 is rotatably connected to the second fixing plate 15. The second transmission wheel 16 can pass through the outer bushing 12 through the communication groove 17 to drive the outer bushing 12 to move along an arc subsequently.

[0041] Please refer to Figures 1-6 , the angle switching assembly 19 includes an adapter plate 1901 fixedly connected to the bottom of the first electric push rod 18. The outer side of the adapter plate 1901 is rotatably connected to a housing 1902. An inner groove 1906 is opened in the adapter plate 1901. A connecting block 1904 is slidably installed in the inner groove 1906. A spring 1905 is fixedly connected between the connecting block 1904 and the adapter plate 1901. A docking hole 1903 for the connecting block 1904 and the first connecting rod 21 to slide through is opened on the housing 1902. In the initial state of the spring 1905, the connecting block 1904 is inFigure 4 In the state of Figure 4 , when the connecting plate 1901 slides along the arc trajectory, the angle of the outer shell 1902 will also change accordingly. When the first connecting rod 21 is moved into the docking hole 1903 and the connecting block 1904 is pushed into the inner groove 1906, when only the part of the connecting block 1904 provided with the inclined surface is located inside the docking hole 1903, the angle change of the connecting plate 1901 will no longer affect the angle of the outer shell 1902. The outer shell 1902 will rotate relative to the connecting plate 1901, and the inclined surface of the connecting block 1904 will abut against the outer shell 1902. The connecting block 1904 will contract into the inner groove 1906, while the outer wall of the first connecting rod 21 remains in contact with the inner wall of the docking hole 1903, so that the outer shell 1902 always remains vertical although it moves along the arc, which is suitable for cutting the flat part of the special-shaped interior trim piece.

[0042] Please refer to Figure 4 , both the connecting block 1904 and the first connecting rod 21 are of frustum of a pyramid structure on the side close to the docking hole 1903. The outer shell 1902 forms a second rotating structure with the connecting plate 1901 through the connecting block 1904 and the first connecting rod 21. The connecting block 1904 and the first connecting rod 21 are symmetrically distributed on the front and back sides of the connecting plate 1901. Through the second rotating structure on the device, when the outer shell 1902 is no longer engaged with the connecting plate 1901, the outer shell 1902 can rotate on the connecting plate 1901, so that the device can keep the laser perpendicular for cutting.

[0043] Please refer to Figure 1 , the guiding assembly 23 includes a guiding ring 2306 rotatably mounted on the outside of the connecting shell 6. Third guiding cylinders 2305 are fixedly connected to both sides of the guiding ring 2306. A second guiding cylinder 2304 is slidably mounted in the third guiding cylinder 2305. A first guiding cylinder 2303 is slidably mounted in the second guiding cylinder 2304. A guiding rod 2302 is slidably mounted in the first guiding cylinder 2303. A connecting block 2301 is fixedly connected to the guiding rod 2302. The second electric push rod 22 is fixedly connected to the connecting block 2301. The guiding ring 2306 can rotate on the connecting shell 6. The connecting block 2301 can slide in the first guiding cylinder 2303 through the guiding rod 2302. The first guiding cylinder 2303 can slide in the second guiding cylinder 2304. The second guiding cylinder 2304 can slide in the third guiding cylinder 2305, so that the device can adapt to different cutting positions and cutting heights while maintaining vertical cutting.

[0044] Please refer to Figures 9-12, the support assembly 28 includes a rotating shaft 2801 fixedly connected to the output shaft of the fourth motor 25. Extension plates 2802 are fixedly connected to the periphery of the rotating shaft 2801. Guide plates 2803 are fixedly connected to the extension plates 2802. Sliders 2807 are slidably installed around the connecting frame 27. A sliding rod 2804 is fixedly connected above the slider 2807. The sliding rod 2804 abuts against the guide plate 2803. A sliding plate 2805 is welded to the top of the sliding rod 2804. An adjusting plate 2806 is slidably installed on the sliding plate 2805. A compression spring 2810 is installed between the slider 2807 and the connecting frame 27. The compression spring 2810 can abut against the sliding rod 2804, the slider 2807 and the sliding plate 2805. Subsequently, the fourth motor 25 can be used to drive the rotation of the rotating shaft 2801, the extension plate 2802 and the guide plate 2803. By using the guide plate 2803 to abut against the sliding rod 2804, the sliding rod 2804 slides on the connecting frame 27, and the compression spring 2810 is compressed, so as to synchronously adjust the initial positions of multiple sliding plates 2805, so as to support interior parts of different sizes subsequently. A guide groove 2809 is formed in the sliding plate 2805. A damping block 2808 is slidably installed in the guide groove 2809. The damping block 2808 is fixedly connected to the adjusting plate 2806. A toothed plate 31 is fixedly connected to the adjusting plate 2806. The toothed plates 31 are evenly distributed on the adjusting plate 2806. The damping block 2808 in the guide groove 2809 can adjust the initial position of the adjusting plate 2806 above the sliding plate 2805, so as to stably support special-shaped parts with different structures subsequently. The toothed plate 31 makes there be a gap between the special-shaped part and the sliding plate 2805 when the device performs laser cutting, avoiding the fusion of the special-shaped part and the sliding plate 2805.

[0045] Please refer to Figures 9-11 , the protection assembly 29 includes a mounting plate 2901 fixedly installed on the adjusting plate 2806. A rubber block 2902 is fixedly connected to the bottom of the mounting plate 2901. A baffle 2903 is fixedly installed on the rubber block 2902. A ball shaft 2904 is rotatably arranged in the baffle 2903. A screw rod 2905 is fixedly connected to the ball shaft 2904. An adjusting block 2906 is threadedly installed on the outer side of the screw rod 2905. A limiting groove 2907 for the up and down movement of the adjusting block 2906 is formed in the mounting plate 2901. By screwing the screw rod 2905 into the adjusting block 2906, the baffle 2903 rotates on the mounting plate 2901 by bending the rubber block 2902, thereby changing the shielding angle and its own height of the baffle 2903 to adjust the shielding position to meet different cutting requirements.

[0046] Please refer to Figure 9 , the lower half of the baffle 2903 is inclined. The center of the ball of the ball shaft 2904 is located inside the baffle 2903. The ball shaft 2904 is adapted to drive the baffle 2903 to rotate on the mounting plate 2901 when the screw rod 2905 is screwed into the adjusting block 2906, asFigure 10 As shown in the figure, when the screw 2905 is screwed into the adjusting block 2906, the ball shaft 2904 pushes the baffle 2903 backward. The ball shaft 2904 also rotates on the baffle 2903, the horizontal height of the ball shaft 2904 changes, and the adjusting block 2906 slides downward.

[0047] The specific implementation process of the present invention is as follows: First, as Figures 1-8 shown, the base 1, the support plate 2 and the support block 3 are used to support the whole device. The device can adjust the cutting angle. The first motor 4 drives the connecting shaft 5 to rotate, driving the whole connecting shell 6 to rotate. The second motor 7 drives the first transmission wheel 8 to rotate, driving the first rotating ring 9 to rotate inside the connecting shell 6, so that the device can perform circumferential cutting. When performing circumferential cutting, the third motor 14 on the folding plate 13 can be used to drive the second transmission wheel 16 on the second fixing plate 15 to rotate. Since the second transmission wheel 16 abuts against the second rotating ring 11, the outer bushing 12 itself moves along the arc track of the first fixing plate 10 to perform arc cutting when the first rotating ring 9 rotates, or first adjust the position of the outer bushing 12, and then rotate the first rotating ring 9 to change the cutting radius during circumferential cutting. As Figures 2-4 shown, the device can switch the cutting angle during laser cutting. In the initial state of the spring 1905, the connecting block 1904 is in the Figure 4 state shown in the figure. Part of the cuboid structure and all of the frustum of pyramid structure of the connecting block 1904 are located inside the docking hole 1903. When the connecting plate 1901 slides along the arc track with the outer bushing 12, the angle of the outer shell 1902 also changes accordingly. At this time, the laser cutter 20 always points to the center of the device.

[0048] As Figures 1-4 shown, the laser cutter 20 can be switched to a state of always remaining vertical. By extending the second electric push rod 22, the first connecting rod 21 is moved into the docking hole 1903. The connecting block 1904 is pushed into the inner groove 1906 through the docking hole 1903, and only the part of the connecting block 1904 with the frustum of pyramid structure is located inside the docking hole 1903. Since the outer wall of the first connecting rod 21 remains in contact with the inner wall of the docking hole 1903 at this time, the movement of the connecting plate 1901 along the arc track and the angle change no longer affect the angle of the outer shell 1902. The outer shell 1902 rotates relative to the connecting plate 1901. The inclined surface of the connecting block 1904 abuts against the outer shell 1902, and the connecting block 1904 contracts into the inner groove 1906. When the outer shell 1902 moves along the arc track, the height of the outer shell 1902 changes. As Figure 1As shown, since the second electric push rod 22 is fixedly connected to the connection block 2301, and the guide ring 2306 can rotate on the connection housing 6, when the angle of the outer housing 1902 changes, the guide ring 2306 can rotate on the connection housing 6. When the outer housing 1902 is at different heights, the connection block 2301 can slide in the first guide cylinder 2303 through the guide rod 2302. The first guide cylinder 2303 can slide in the second guide cylinder 2304, and the second guide cylinder 2304 can slide in the third guide cylinder 2305. As a result, the device can adapt to different cutting positions and cutting heights. And since the first connecting rod 21 itself does not rotate, the outer housing 1902 can always remain vertical while moving along an arc, which is suitable for cutting the flat part of the special-shaped interior trim parts.

[0049] As Figures 1-5 and Figures 9-12 shown, when the outer bushing 12 moves to both sides of the first fixing plate 10 and the second rotating ring 11, at this time, the side cutting work of the automotive interior trim part of the cover structure can be realized by rotating the first rotating ring 9. During cutting, in order to avoid the transmitted laser affecting the other side of the interior trim part after cutting, the positions of the support components 28 and the protection components 29 at various places on the connecting frame 27 can be adjusted according to the cutting position. First, the initial height of the connecting frame 27 is adjusted by the third electric push rod 24, and then the fourth motor 25 drives the rotating shaft 2801 to rotate counterclockwise, driving the extension plate 2802 and the guide plate 2803 to rotate. As Figure 9 shown, the arc-shaped guide plate 2803 abuts against the sliding rod 2804. The sliding rod 2804 slides on the connecting frame 27, and the compression spring 2810 between the connecting frame 27 and the slider 2807 is compressed. The distance from the sliding plate 2805 to the central axis of the rotating shaft 2801 changes, so as to synchronously adjust the initial positions of multiple sliding plates 2805 and the protection components 29, so as to support interior trim parts of different sizes subsequently. As Figures 9-11As shown in the figure, the position and angle of the baffle 2903 are adjusted according to the position and angle of the laser cutting. The screw rod 2905 is rotated so that the screw rod 2905 is screwed into the inside of the adjusting block 2906. The ball shaft 2904 pushes the baffle 2903, and the baffle 2903 rotates on the mounting plate 2901 through the rubber block 2902, thereby changing the shielding angle and the height of the baffle 2903 itself to adapt to different cutting positions and cutting angles. The initial position of the adjusting plate 2806 on the sliding plate 2805 can also be adjusted by the damping block 2808 in the guide groove 2809, so as to stably support interior trim parts of different structures subsequently. The initial position of the baffle 2903 can also be accurately adjusted according to the position of the laser cutting. The toothed plate 31 ensures that there is enough space between the interior trim part and the sliding plate 2805 when the device supports the interior trim part. Therefore, the synchronous adjustment structure on the support assembly 28 of the device can not only adjust the degree of diffusion of the four sliding plates 2805 to adapt to the support of interior trim parts of different sizes, but also change the initial positions of the four protection assemblies 29, so as to adjust the shielding position when laser cutting the side of the interior trim part subsequently, and avoid the transmitted laser affecting the interior trim part.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
