Compared with traditional cutting devices, laser cutting devices have the advantages of high flexibility and high precision. However, the existing laser cutting devices still have some shortcomings when used.

[0003] For example, the invention patent with publication number CN106378537B discloses a laser cutting machine and 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, 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 stepper 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, the camera device is arranged at the entrance of the cutting machine and located on the upper part of the support frame, and the electric control device is arranged outside the support frame.

[0004] Although the above device can realize the function of special-shaped cutting, it cannot shield the side of the special-shaped part when it is converted to horizontal cutting. In particular, special-shaped parts of automobile interior such as covers cannot be cut while protecting the side of the interior when laser cutting such interior parts. This results in that when cutting one side of the interior, the side opposite to the cutting surface will also be affected by the cutting. In addition, the existing cutting machine cannot adaptively adjust the cutting angle or keep the cutting angle unchanged when moving along the arc cutting track, 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, which affects the cutting effect. Summary of the invention

[0016] Compared with the related art, the present invention has the following beneficial effects: 1. The present invention uses a protective component to block the transmitted laser after cutting one side of the interior decoration part, thereby preventing it from affecting the other side of the interior decoration part. In addition, since the baffle is inclined, the transmitted laser will only be reflected on the adjustment plate even if it is reflected, thereby preventing the device from affecting the other side of the interior decoration part and the bottom surface of the interior decoration part when performing laser cutting on the side of the interior decoration part, thereby ensuring the laser cutting quality of the device and solving the problem that the existing laser cutting device cannot block the side of the special-shaped part when converting to horizontal cutting.

[0017] 2. The present invention sets a support component. When the fourth motor drives the rotating shaft on the support component to rotate, the guide plate on the extension plate abuts against the sliding rod, and the sliding rods around the connecting frame will gather toward the middle, so that the protective components at various positions gather toward the middle. The position of each baffle can be adjusted according to the cutting position to ensure that the transmitted laser will not be emitted to the other side of the interior decoration, thereby ensuring the stability of the device during operation and the cutting quality.

[0018] 3. By setting the angle switching component, the first connecting rod, the second electric push rod and the guide component, when the first connecting rod is located on the outside of the docking hole, no matter how the outer bushing on the device slides, the laser cutter below the outer bushing always points to the circular position of the second rotating ring, and 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, and the outer shell abuts against the four-sided pyramid of the connecting block so that the connecting block does not affect the normal rotation of the outer shell. Subsequently, the connecting block can be automatically reset under the action of the spring force, thereby switching the laser cutting angle according to the structure of the interior decoration part, 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. The device can adjust the angle between the laser and the surface of the interior decoration part during cutting according to the structure of the special-shaped interior decoration part, and has the advantage of stronger adaptability.

[0019] 4. By setting a rotatable connecting shell and a first rotating ring rotatable in the connecting shell, the device can adjust the cutting trajectory, and can perform not only circumferential cutting but also arc cutting. With the outer sleeve sliding on the second rotating ring, the device can adjust the cutting radius during circumferential cutting, thereby enhancing the cutting effect of the device.

The blocking position of the transmitted laser at each location can be synchronously adjusted by the support component 28 to prevent the transmitted laser from affecting the interior parts, thereby ensuring the laser cutting effect of the device.

[0025] See also Figure 1 The support plate 2 and the support block 3 are symmetrically distributed on the left and right sides of the connecting shell 6. The base 1, the support plate 2 and the support block 3 are fixedly connected to form an integral structure.

The connecting shell 6 can rotate on the support block 3 to change the initial cutting position.

[0026] See also 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 patterns.

The outer bushing 12 forms a sliding structure between the second transmission wheel 16 and the second rotating ring 11 and the first fixed plate 10. Through the sliding structure on the device, the device changes the cutting range when performing circumferential cutting, thereby meeting different cutting requirements for use.

[0027] See also Figure 5-Figure 8 The inner wall of the outer bushing 12 fits with the outer wall of the first fixed plate 10, so that the outer bushing 12 can slide smoothly on the first fixed plate 10 to ensure the stability of the device during cutting.

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, and the connecting block 1904 will shrink into the inner groove 1906, while the outer wall of the first connecting rod 21 remains in abutment with the inner wall of the docking hole 1903, so that although the outer shell 1902 moves along the arc, it always remains in a vertical state, which is suitable for cutting the flat part of special-shaped interior decoration parts.

[0029] See also Figure 4 The connecting block 1904 and the first connecting rod 21 have a quadrangular pyramid structure on one side near the docking hole 1903.

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 shell 1902 is no longer engaged with the connecting plate 1901, the shell 1902 can rotate on the connecting plate 1901, so that the device keeps the laser vertical for cutting.

[0032] See also Figure 9-11 The protection component 29 includes a mounting plate 2901 fixedly mounted on the adjustment plate 2806, a rubber block 2902 is fixedly connected to the bottom of the mounting plate 2901, a baffle 2903 is fixedly mounted on the rubber block 2902, a ball shaft 2904 is rotatably arranged in the baffle 2903, a screw 2905 is fixedly connected to the ball shaft 2904, an adjustment block 2906 is threadedly mounted on the outer side of the screw 2905, and a limiting groove 2907 for the adjustment block 2906 to move up and down is provided on the mounting plate 2901. By screwing the screw 2905 into the interior of the adjustment block 2906, the baffle 2903 is rotated on the mounting plate 2901 by bending the rubber block 2902, thereby changing the shielding angle and the height of the baffle 2903, so as to adjust the shielding position to meet different cutting needs.

[0033] See also Fig. 9 The lower half of the baffle 2903 is inclined, the center of the ball shaft 2904 is located inside the baffle 2903, and the ball shaft 2904 is suitable for driving the baffle 2903 to rotate on the mounting plate 2901 when the screw 2905 is screwed into the adjusting block 2906. Fig.10 As shown, when the screw 2905 is screwed into the adjusting block 2906, the ball shaft 2904 pushes the baffle 2903 backwards, and 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.

[0034] The specific implementation process of the present invention is as follows: First, Figure 1-Figure 8 As shown, the base 1, the support plate 2 and the support block 3 are used to support the device as a whole. The device can adjust the cutting angle. The first motor 4 drives the connecting shaft 5 to rotate, driving the connecting shell 6 to rotate as a whole. 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 drive the second transmission wheel 16 on the second fixed plate 15 to rotate. Since the second transmission wheel 16 will abut against the second rotating ring 11, the outer bushing 12 itself will move along the arc trajectory of the first fixed plate 10, so as to perform arc cutting when the first rotating ring 9 rotates, or the position of the outer bushing 12 can be adjusted first, and then the first rotating ring 9 can be rotated to change the cutting radius during circumferential cutting. Figure 2-Figure 4 As shown, the device can switch the cutting angle during laser cutting. The spring 1905 is in the initial state and the connecting block 1904 is in Figure 4 In the state, the connecting block 1904 has a part of the rectangular parallelepiped structure and the entire four-sided pyramid structure located inside the docking hole 1903. When the connecting plate 1901 slides along the arc track with the outer sleeve 12, the angle of the shell 1902 will also change accordingly, and the laser cutter 20 always points to the center of the device.

[0035] like Figure 1-Figure 4 As shown, the laser cutter 20 can be switched to a state where it always remains vertical. By extending the second electric push rod 22, the first connecting rod 21 is moved to the inside of the docking hole 1903, and the connecting block 1904 is pushed to the inside of the inner groove 1906 through the docking hole 1903, and the portion of the connecting block 1904 that only has a quadrangular pyramid structure is kept inside the docking hole 1903. Since the outer wall of the first connecting rod 21 is kept in contact with the inner wall of the docking hole 1903 at this time, the connecting plate 1901 moves along an arc trajectory and changes its angle, which no longer affects 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 shrink into the inner groove 1906. When the outer shell 1902 moves along an arc trajectory, the height of the outer shell 1902 will change. Figure 1As shown, since the second electric push rod 22 and the connecting block 2301 are fixedly connected, and the guide ring 2306 can rotate on the connecting shell 6, when the angle of the shell 1902 changes, the guide ring 2306 can rotate on the connecting shell 6, and when the shell 1902 is at different heights, the connecting 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, so that the device can adapt to different cutting positions and cutting heights, and since the first connecting rod 21 itself does not rotate, the shell 1902 can move along the arc but always remain in a vertical state, which is suitable for cutting the flat part of special-shaped interior parts.

[0036] like Figure 1-Figure 5 and Figure 9-12 As shown, when the outer bushing 12 moves to both sides of the first fixing plate 10 and the second rotating ring 11, the first rotating ring 9 can be rotated to realize the side cutting of the automobile interior decoration of the cover structure. During cutting, in order to avoid the transmitted laser from affecting the other side of the interior decoration after cutting, the positions of the supporting components 28 and the protective components 29 at various locations 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 rotating shaft 2801 is driven to rotate counterclockwise by the fourth motor 25, so as to drive the extension plate 2802 and the guide plate 2803 to rotate, as shown in FIG. Fig. 9 As shown, the guide plate 2803 of the arc structure abuts against the slide bar 2804, and the slide bar 2804 slides on the connecting frame 27, and the compression spring 2810 between the connecting frame 27 and the slide block 2807 is compressed, and the distance between the slide plate 2805 and the central axis of the rotating shaft 2801 changes, thereby synchronously adjusting the initial positions of multiple slide plates 2805 and the protective assembly 29, so as to support interior parts of different sizes later. Figure 9-11As shown, the position and angle of the baffle 2903 are adjusted according to the position and angle of the laser cutting, the screw 2905 is rotated so that the screw 2905 is screwed into the inside of the adjustment block 2906, and the ball shaft 2904 pushes the baffle 2903, and the baffle 2903 is rotated on the mounting plate 2901 through the rubber block 2902, thereby changing the shielding angle and the height of the baffle 2903 to adapt to different cutting positions and cutting angles. The initial position of the adjustment plate 2806 on the slide plate 2805 can also be adjusted by the damping block 2808 in the guide groove 2809, so as to provide stable support for the interior decoration parts of different structures in the future, and the initial position of the baffle 2903 can also be accurately adjusted according to the position of the laser cutting, and the tooth plate 31 ensures that when the device supports the interior decoration parts, there is enough space between the interior decoration parts and the slide plate 2805. Therefore, the synchronous adjustment structure on the support component 28 of the device can not only adjust the diffusion degree of the four slides 2805 to adapt to the support of interior parts of different sizes, but also change the initial position of the four protective components 29 so that when laser cutting is performed on the side of the interior part, the shielding position can be adjusted to prevent the transmitted laser from affecting the interior part.
