Description

Technical Field

[0001] This utility model relates to the field of interior panel processing technology, specifically a fixing device for processing automotive interior panels. Background Technology

[0002] Traditional fixing devices mostly employ a "single support mode," relying either on edge-fixed support rods to bear the workpiece weight or on a bottom plate for overall lifting. This makes it impossible to flexibly adjust the support scheme according to the size and weak areas of the interior panel. Furthermore, the personalized design of automotive interior panels necessitates processing workpieces of various specifications and shapes on the same production line, but the locking structures of traditional fixing devices are mostly "rigid fixations," unable to adapt to the fitting requirements of workpieces with different shapes and angles. Therefore, those skilled in the art have provided a fixing device for processing automotive interior panels to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a fixing device for processing automotive interior panels, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fixing device for processing automotive interior panels includes a floor, a bottom support assembly on the upper surface of the floor, a side guard plate fixedly connected to the floor, a receiving plate slidably connected to the inner side wall of the side guard plate, a pair of limiting rods fixedly connected to the upper surface of the floor, the receiving plate slidably connected to the limiting rods, and a locking assembly for fixing the workpiece on the upper surface of the receiving plate.

[0005] Furthermore, the bottom support assembly includes threaded mounting holes, a mounting plate, and a support rod. A set of evenly distributed threaded mounting holes are provided on the upper surface of the floor. The mounting plate is threadedly connected to the floor through the threaded mounting holes, and the support rod is fixedly connected to the upper end of the mounting plate.

[0006] Furthermore, the support assembly also includes support rods, with a pair of support rods fixedly connected to the upper surface of the floor and located at the edge of the floor.

[0007] Furthermore, the locking assembly includes a limiting plate, a connecting block, and a support column. The connecting block is fixedly connected to the receiving plate, the limiting plate is rotatably connected inside the connecting block, and the support column is fixedly connected to the upper surface of the limiting plate.

[0008] Furthermore, the locking assembly also includes a support pad, a lower extension arm, and a lower connecting ring. The lower connecting ring is rotatably connected to the surface of the support column, the lower extension arm is fixedly connected to the surface of the lower connecting ring, and the support pad is fixedly connected to the upper surface of the lower extension arm.

[0009] Furthermore, the locking assembly also includes an upper extension arm, an adjusting clamping rod, a connecting plate, and an upper connecting ring. The connecting plate is fixedly connected to the upper surface of the lower connecting ring, and the upper connecting ring is fixedly connected to the upper end of the connecting plate. The upper connecting ring is rotatably connected to the support column. The upper extension arm is fixedly connected to the surface of the upper connecting ring, and the adjusting clamping rod is threaded onto the upper extension arm.

[0010] Furthermore, an electro-hydraulic telescopic rod is fixedly connected to the floor, and a push rod is provided at the output end of the electro-hydraulic telescopic rod, with the upper end of the push rod fixedly connected to the receiving plate.

[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The support rods at the edge of the floor serve as the main support structure. Relying on their stable connection characteristics, they can bear the overall weight of the interior panel. Especially for large-sized, long-span interior panels, they can effectively prevent sagging in the middle of the workpiece due to the lack of main support. At the same time, the "set of evenly distributed threaded mounting holes" on the floor surface can flexibly adjust the number, spacing, and position of the mounting plates and support rods. As auxiliary fixing components, the support rods can provide targeted supplementary support according to the weak areas and irregular contours (such as grooves and hollow structures) of the interior panel. This not only prevents local shaking during workpiece processing but also avoids structural deformation caused by excessive stress on a single point of the main support, achieving a dual adaptation effect of "main support stabilizing the foundation and auxiliary fixing supplementing details." 2. The lower connecting ring / upper connecting ring is rotatably connected to the support column. The angle of the limiting plate and the support position of the lower extension arm and the upper extension arm can be adjusted according to the arc or irregular contour of the interior panel. This enables the fitting and fixing of interior panels of different shapes such as "flat type, arc type, and concave-convex type". There is no need to customize tooling for each specification, which greatly reduces equipment replacement costs and processing preparation time. 3. The electro-hydraulic telescopic rod can automatically raise and lower the height of the receiving plate without requiring operators to bend over or lift it for adjustment, greatly reducing labor intensity. More importantly, for processing and switching between different specifications of interior panels, there is no need to manually disassemble or elevate parts. The receiving plate can be quickly adjusted to the height that matches the current workpiece simply through electro-hydraulic control. Compared with traditional manual adjustment, it saves more than 80% of preparation time, which is especially suitable for batch processing scenarios and effectively improves overall processing efficiency.

[0016] In this embodiment, the locking assembly includes a limiting plate 14, a connecting block 15, and a support column 16. The connecting block 15 is fixedly connected to the receiving plate 6, and the limiting plate 14 is rotatably connected inside the connecting block 15. The support column 16 is fixedly connected to the upper surface of the limiting plate 14. The locking assembly also includes a support pad 11, a lower extension arm 12, and a lower connecting ring 13. The lower connecting ring 13 is rotatably connected to the surface of the support column 16, and the lower extension arm 12 is fixedly connected to the surface of the lower connecting ring 13. A support column 16 is fixedly connected to the upper surface of the lower extension arm 12. The support pad 11 and the locking assembly further include an upper extension arm 9, an adjusting clamping rod 10, a connecting plate 17, and an upper connecting ring 18. The connecting plate 17 is fixedly connected to the upper surface of the lower connecting ring 13, and the upper connecting ring 18 is fixedly connected to the upper end of the connecting plate 17. The upper connecting ring 18 is rotatably connected to the support column 16. The upper extension arm 9 is fixedly connected to the surface of the upper connecting ring 18, and the adjusting clamping rod 10 is threaded onto the upper extension arm 9. An electro-hydraulic telescopic rod 20 is fixedly connected to the floor 1, and the output end of the electro-hydraulic telescopic rod 20... A push rod 19 is provided, and the upper end of the push rod 19 is fixedly connected to the receiving plate 6; the side guard plate 5 is fixed to the upper surface of the floor 1 by bolts; a pair of limit rods 7 are vertically welded to the front and rear ends (located inside the side guard plate 5) of the upper surface of the floor 1; guide holes are opened at corresponding positions on the receiving plate 6, and the limit rods 7 pass through the guide holes to ensure that the receiving plate 6 does not deviate or shake when it is raised or lowered; three connecting blocks 15 are welded to the upper surface of the receiving plate 6, and each set of connecting blocks 15 is rotatably connected to a limit plate 14 by a pin; the upper surface of the limit plate 14 A support column 16 is vertically welded at the center position. The outer wall of the support column 16 needs to be polished smooth to provide a basis for subsequent rotation and adjustment. A lower connecting ring 13 is fitted onto the support column 16. A lower extension arm 12 is symmetrically welded to the outer wall of the lower connecting ring 13. A support pad 11 is glued to the upper surface of the lower extension arm 12. A connecting plate 17 is vertically welded to the upper surface of the lower connecting ring 13. An upper connecting ring 18 is welded to the upper end of the connecting plate 17. An upper extension arm 9 is welded to the outer wall of the upper connecting ring 18. An M8 threaded hole is machined on the upper extension arm 9, and an adjusting clamping rod 10 is screwed into the threaded hole.

[0017] For processing large-sized, long-span interior trim panels (such as door trim panels with a length of 2000mm): use the support rod 8 at the edge of the floor 1 as the main support, directly supporting the weight of both ends of the trim panel; at the same time, observe the weak areas in the middle of the trim panel (such as hollow structures or thin areas), and screw bolts into the threaded mounting holes 2 at the corresponding positions to fix 2-3 mounting plates 3. The support rod 4 welded to the upper end of the mounting plate 3 serves as an auxiliary support, achieving "stable foundation at both ends and supplementary support in the middle," preventing the workpiece from sagging. Start the electro-hydraulic telescopic rod 20 through the external PLC control system (or manual operation panel), and adjust the height of the supporting plate 6 according to the size of the trim panel to be processed. After the positions of each extension arm are adjusted to the correct position, manually turn the anti-slip knob of the adjusting clamping rod 10 to slowly press the lower rubber pressure head down onto the upper surface of the trim panel until the support pad 11 and the rubber pressure head together form "lower support and upper pressure." Once the workpiece is in a stable state and fixed, the processing equipment can be started. When fixing the mounting plate 3, the angle of the mounting plate 3 can be adjusted with the threaded mounting hole 2 as the axis, thereby adjusting the position of the support rod 4 within a certain range to ensure that the workpiece is better supported.

[0018] The support rod 8 at the edge of the floor 1 serves as the main support structure. Its stable connection characteristics allow it to support the overall weight of the interior trim panel, especially effective for large-sized, long-span interior trim panels, preventing sagging in the middle of the workpiece due to lack of main support. Simultaneously, a set of evenly distributed threaded mounting holes 2 on the surface of the floor 1 allows for flexible adjustment of the number, spacing, and position of the mounting plate 3 and the support rod 4. The support rod 4, as an auxiliary fixing component, can provide targeted support for weak areas and irregular contours (such as grooves and hollow structures) of the interior trim panel, preventing localized shaking during workpiece processing and avoiding structural deformation caused by excessive stress on a single point of the main support. This achieves a dual adaptation effect of "main support stabilizing the foundation, auxiliary fixing supplementing details." The lower connecting ring 13 / upper connecting ring 18 is rotatably connected to the support column 16, allowing adjustment of the angle of the limiting plate 14 and the support positions of the lower extension arm 12 and upper extension arm 9 according to the arc or irregular contour of the interior trim panel, achieving support for "flat, arc, and concave / convex" shapes. The fitting and fixing of interior panels of different shapes eliminates the need for custom tooling for each specification, significantly reducing equipment replacement costs and processing preparation time. The electro-hydraulic telescopic rod 20 enables automatic raising and lowering of the receiving plate 6, eliminating the need for operators to bend over or lift for adjustment, greatly reducing labor intensity. More importantly, for processing and switching between different specifications of interior panels, there is no need to manually disassemble or elevate parts. The receiving plate 6 can be quickly adjusted to a height suitable for the current workpiece simply through electro-hydraulic control, saving more than 80% of preparation time compared to traditional manual adjustment. It is especially suitable for batch processing scenarios and effectively improves overall processing efficiency.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
