Description

Technical Field

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

[0002] In the automotive manufacturing industry, surface coating of automotive interior plastic panels is a key process for improving the aesthetics, wear resistance, and corrosion resistance of the interior. The fixing device, as a core auxiliary equipment in the coating process, directly affects the coating quality and production efficiency. With the diversification of automotive interior designs, the shape of plastic panels has gradually evolved from regular rectangles to irregular structures, and the surface often has irregular features such as curvature, grooves, or protrusions. Traditional fixing devices are no longer sufficient to meet processing requirements. In existing technologies, automotive interior plastic panel coating fixing devices mostly use rigid clamps to directly hold the edges of the plastic panels. For irregular panels of different lengths and widths, frequent clamp changes are required, which not only increases equipment costs but also prolongs production changeover time and reduces processing efficiency. Therefore, new technical solutions are needed to address this issue. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, a fixing device for spraying and processing plastic panels for automotive interiors includes two parallel supporting base rods 1. A fixing main rod 2 is vertically installed at the center of the top of each supporting base rod 1. A main shaft seat 9 is installed at the top of one side of the fixing main rod 2, and a fixing frame 12 is installed at the top of the other side of the fixing main rod 2. A rotating seat 13 is installed at the upper end of the fixing frame 12. A rotating shaft 14 is installed inside the rotating seat 13. A main rotating shaft 8 is installed inside the main shaft seat 9. A plastic panel fixing plate a11 is installed at the end of the rotating shaft 14. A plastic panel fixing plate b10 is installed at the end of the main rotating shaft 8. Clamping plates 17 are fitted on the opposite side walls of the plastic panel fixing plates a11 and b10. Irregularly shaped top parts 16 are evenly and equidistantly fitted on the side walls of the clamping plates 17 along their axis.

[0020] In the specific implementation process, the two supporting base rods 1 are square tube structures, arranged in parallel left and right. The top center of each supporting base rod 1 is vertically fixed with a main rod 2. The top of the right fixed main rod 2 is mounted with a main rotating shaft 8 through a main shaft seat 9, and the top of the left fixed main rod 2 is mounted with a rotating shaft 14 through a rotating seat 13, thereby realizing the rotation of plastic plate fixing plate a11 and plastic plate fixing plate b10. The inner walls of the two plastic plate fixing plates are fitted with irregular surface top pieces 16 through clamping plates 17. The inner walls of clamping plates 17 are arranged with multiple layers along their axis from the inside to the outside. The irregular surface top pieces 16 are arranged at the above-mentioned multi-layer structure, thereby being applied to the irregular plastic plate surface.

[0021] In some technical solutions, an electric push rod 3 is installed at the center of the inner wall of one side of the supporting bottom rod 1, and a fixed seat 7 is installed at the center of the inner wall of the other side of the supporting bottom rod 1. The output end of the electric push rod 3 is connected to the fixed seat 7, and the top of the supporting bottom rod 1 is equipped with reinforcing ribs 6 on both sides of the fixed main rod 2.

[0022] In the specific implementation process, the supporting base rod 1 on one side is fixed, and the extension and retraction of the electric push rod 3 drives the supporting base rod 1 on the other side to move left and right, thereby clamping the plastic plate.

[0023] In some technical solutions, drive wheels 4 are installed on both sides of the bottom end of the two supporting base rods 1, and limit rods 5 are installed at the four corners of the opposite side walls of the two supporting base rods 1.

[0024] In the specific implementation process, the movement of the bearing base rod 1 can be realized by setting the drive wheel 4, and the drive wheel 4 is equipped with a brake. The movement of the two bearing base rods 1 can be limited by setting the limit rod 5.

[0025] In some technical solutions, the irregular surface top part 16 includes a mounting plate 19 installed on the side wall of the clamping plate 17. The side wall of the mounting plate 19 is vertically mounted with a telescopic rod 20. The end of the telescopic rod 20 is mounted with a universal seat 22. The universal seat 22 is equipped with a universal ball 23 inside.

[0026] In the specific implementation process, the telescopic rod 20 is vertically fixed on the mounting plate 19. The extension and retraction of the telescopic rod 20 drives the extension and retraction of the universal seat 22, which then contacts the irregular plastic plate under the rolling of the universal ball 23.

[0027] In some technical solutions, a support spring 21 is fitted on the outside of the telescopic rod 20 between the universal joint 22 and the mounting plate 19.

[0028] In practice, the irregular surface of the plastic sheet is clamped and fixed by the cooperation of the telescopic rod 20 and the support spring 21.

[0029] In some technical solutions, the inner wall of the universal seat 22 is provided with rotating cavities 18 evenly spaced along its axis, and ball bearings 24 are installed inside the rotating cavities 18, with the ball bearings 24 fitting together with the universal ball 23.

[0030] In the specific implementation process, the ball bearing 24 rolls in the rotating cavity 18, thereby preventing the universal ball 23 from getting stuck in the universal seat 22.

[0031] In some technical solutions, the inner wall of the rotating seat 13 is provided with a smooth surface 15, and the smooth surface 15 is fitted to the outer wall of the rotating shaft 14.

[0032] In practice, the smooth surface 15 can improve the rotation efficiency of the rotating shaft 14 within the rotating seat 13.

[0033] Working principle:

[0034] The car interior plastic panel is placed between the plastic panel fixing plate a11 and the plastic panel fixing plate b10. Then, the electric push rod 3 is retracted by controlling it. When the irregular surface top piece 16 on the clamping plate 17 contacts the surface of the plastic panel, the universal ball 23 adapts to the protrusions, grooves or curvatures of the panel surface through the universal seat 22. At the same time, the telescopic rod 20 is compressed, and the support spring 21 generates a reverse elastic force, pushing the universal ball 23 to fit tightly against the surface of the panel, forming a multi-point uniform pressing, ensuring that the irregularly shaped panel can also be stably fixed.
