[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 8 As shown, this utility model provides an automotive interior trim cutting device, including a testing table 1, a limiting block 2 on the top of the testing table 1, a gantry frame 3 slidably mounted on the testing table 1, a fixing component 8 for fixing the automotive interior trim on the top of the testing table 1, a transverse driving component for driving the gantry frame 3 to move on the bottom of the testing table 1, a first linear actuator 4 on the top of the gantry frame 3, a cutting blade 5 at the working end of the first linear actuator 4, an anti-wrinkle component 6 on the gantry frame 3, the anti-wrinkle component 6 including a fixing frame 64 for fixing the perimeter of the area to be cut and a threaded driving component for driving the fixing frame 64 to move, and a smoothing component 7 for smoothing the interior trim on the gantry frame 3.

[0028] By placing the automotive interior parts on the inspection table 1 and securing them as a whole with the fixing component 8, stability during the cutting process is ensured. Subsequently, the smoothing component 7 is activated to smooth the interior parts, eliminating wrinkles and unevenness on their surface. The gantry 3 is moved horizontally by the lateral drive component, adjusting the cutting blade 5 to the cutting position. The threaded drive component in the anti-wrinkle component 6 drives the fixing frame 64 to move, fixing the area around the cutting position to prevent movement or deformation of the interior parts during cutting. This avoids burrs, cracks, or uneven surfaces during cutting, improving the quality and aesthetics of the cut.

[0029] See Figures 1 to 4 As shown, the threaded drive component includes an extension block 61; the extension block 61 is disposed on both sides of the gantry 3, and a second threaded rod 62 is threadedly connected to the extension block 61. A knob 63 is disposed at one end of the second threaded rod 62, and a fixing bracket 64 is disposed at the other end of the second threaded rod 62.

[0030] By manually rotating knob 63 according to the dimensions of the interior trim to be cut, the second threaded rod 62 is driven to rotate and move linearly within extension block 61. Due to the interaction of the threads, the linear movement of the second threaded rod 62 will drive the fixing bracket 64 to move closer to the cutting position until the fixing bracket 64 can tightly fit and fix the perimeter of the part to be cut, thereby preventing the interior trim from moving or deforming during the cutting process, ensuring that the perimeter of the part to be cut is firmly fixed, avoiding the generation of burrs, cracks or uneven surfaces during the cutting process, and improving the cutting quality and aesthetics.

[0031] See Figure 4 As shown, a rubber layer is provided at the bottom of the fixing bracket 64.

[0032] When the fixing bracket 64 is tightly attached to and fixes the interior trim to be cut, the rubber layer contacts the surface of the interior trim and generates sufficient friction to effectively prevent the interior trim from sliding or shifting due to force during the cutting process.

[0033] See Figure 5 and Figure 6 As shown, the leveling assembly 7 includes a second linear driver 71; the second linear driver 71 is disposed inside the gantry 3, and a rectangular frame 72 is disposed at the output end of the second linear driver 71. A left extension plate 73 is disposed at the bottom of the rectangular frame 72. A rectangular groove is opened on the left extension plate 73, and a third threaded rod 74 is disposed in the rectangular groove. A second motor 75 is disposed at one end of the left extension plate 73. The output end of the second motor 75 is connected to the third threaded rod 74. A drive block 76 is threadedly connected to the third threaded rod 74, and a leveling wheel 77 is disposed on one side of the drive block 76.

[0034] The gantry 3 is moved to the cutting position by the lateral drive component, and the second linear actuator 71 (which can be a cylinder) is activated, which drives the rectangular frame 72 to move in a straight line. The second motor 75 is activated, which drives the third threaded rod 74 to rotate. The rotation of the third threaded rod 74 drives the drive block 76 to move, and the movement of the drive block 76 drives the smoothing wheel 77 to move. The smoothing wheel 77 contacts the automotive interior part to be processed and smooths the surface of the automotive interior part, improving the cutting quality.

[0035] See Figure 5 and Figure 6As shown, the bottom of the rectangular frame 72 is located on one side of the left extension plate 73 and a right extension plate 78 is provided. A limit slider is provided on one side of the smoothing wheel 77, and a limit groove is provided on the right extension plate 78 for the limit slider to move.

[0036] When the drive block 76 moves, it drives the smoothing wheel 77 to move. The smoothing wheel 77 moves within the limit groove through the limit slider, thereby improving the stability of the smoothing wheel 77's movement.

[0037] See Figure 7 and Figure 8 As shown, the fixed component 8 includes a movable frame 81 and a movable rod 82; there are two movable frames 81, and both movable frames 81 are slidably mounted on the testing table 1; there are three movable rods 82, and all of them are vertically mounted on the movable frame 81. One end of the movable rod 82 is provided with a pressure plate 83, and the other end of the movable rod 82 is provided with a pull plate 84. A spring 85 is also sleeved on the movable rod 82. One end of the spring 85 abuts against the top of the pressure plate 83, and the other end of the spring 85 abuts against the inner side of the movable frame 81.

[0038] The automotive interior trim piece to be processed is placed on the inspection table 1. Then, the pull plate 84 is manually pulled, causing the movable rod 82 to move upward. As the movable rod 82 moves, the pressure plate 83 gradually rises, and at the same time, the spring 85 is compressed. At this time, the positions of the two movable frames 81 are adjusted until the movable frames 81 move to both ends of the automotive interior trim piece. The pull plate 84 is then released, and the spring 85 recovers its elastic deformation, driving the pressure plate 83 to fix the automotive interior trim piece, thereby ensuring stability during the cutting process.

[0039] See Figure 8 As shown, a fixing block 86 is provided on the inner side of the movable frame 81, and a threaded bolt 87 is connected to the fixing block 86. A screw hole for the bolt 87 to be threaded is also provided on the top of the limiting block 2.

[0040] By moving the two movable frames 81 to the appropriate position, passing the bolt 87 through the fixing block 86, and rotating the bolt 87 to engage with the screw hole on the limiting block 2 until the bolt 87 is fully screwed into the screw hole, the movable frame 81 is firmly fixed on the limiting block 2, thereby improving the stability of the automotive interior parts after fixing.

[0041] See Figure 2 As shown, the transverse drive component includes a first threaded rod 31 and a first motor 32; the first threaded rod 31 is disposed at the bottom of the testing table 1; the first motor 32 is disposed at one end of the testing table 1, the output end of the first motor 32 is connected to the first threaded rod 31, and a movable plate 33 is threadedly connected to the first threaded rod 31, the top of the movable plate 33 is connected to the bottom of the gantry 3.

[0042] When it is necessary to adjust the position of the gantry 3, the first motor 32 is started, which drives the first threaded rod 31 to rotate. The rotation of the first threaded rod 31 drives the moving plate 33 to move, which in turn drives the gantry 3 to move, thereby achieving the purpose of adjusting the position of the gantry 3.

[0043] By placing the automotive interior trim part on the inspection table 1, the pull plate 84 is manually pulled, causing the movable rod 82 to move upward. As the movable rod 82 moves, the pressure plate 83 gradually rises, and the spring 85 is compressed. At this time, the positions of the two moving frames 81 are adjusted until the moving frames 81 move to both ends of the automotive interior trim part. The pull plate 84 is then released, and the spring 85 recovers its elastic deformation, causing the pressure plate 83 to fix the automotive interior trim part, thus ensuring stability during the cutting process. Subsequently, the gantry frame 3 is moved to the cutting position by the transverse drive component, and the second linear actuator 71 (which can be a cylinder) is activated, driving the rectangular frame 72 to move in a straight line. By activating the second motor 75, the second motor 75 drives the third threaded rod 74 to rotate. The rotation of the third threaded rod 74 drives the drive block 76 to move, and the drive block 76 moves the smoothing wheel 77. The smoothing wheel 77 contacts the automotive interior trim part to be processed and smooths the surface of the automotive interior trim part, improving the cutting quality. By manually rotating knob 63 according to the dimensions of the interior trim to be cut, the second threaded rod 62 is driven to rotate and move linearly within extension block 61. Due to the interaction of the threads, the linear movement of the second threaded rod 62 will drive the fixing bracket 64 to move closer to the cutting position until the fixing bracket 64 can tightly fit and fix the perimeter of the part to be cut, thereby preventing the interior trim from moving or deforming during the cutting process, ensuring that the perimeter of the part to be cut is firmly fixed, avoiding the generation of burrs, cracks or uneven surfaces during the cutting process, and improving the cutting quality and aesthetics.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
