[0003] According to a painting jig with the patent authorization publication number of CN212681427U and the publication date of March 12, 2021, it includes a positioning table. A positioning seat is installed on the upper side of the positioning table through a telescopic rod. A pressing rod is inserted into the positioning seat. The lower side of the telescopic rod is drivingly connected to a cylinder, and the cylinder is installed at the lower part of the positioning table. A lower frame body is installed on the lower side of the positioning table. A lower support leg is installed in the middle of the lower side of the lower frame body through a rotating shaft. The lower end of the rotating shaft is drivingly connected to a motor. A plug hole is opened in the positioning seat. The pressing rod is horizontally inserted into the plug hole, and a positioning bolt is installed on the positioning seat above the plug hole. The utility model drives the pressing rod to lift and adjust through a cylinder, which is convenient for quickly clamping and positioning plastic parts. The positioning is convenient and fast. Moreover, the pressing rod is inserted into the positioning seat, which is convenient for adjusting the use length of the pressing rod according to needs to meet the positioning of plastic parts of different sizes; although this device can fix plastic parts of different sizes, since the fixing mechanism of this device cannot be deformed and adjusted, it cannot fix some plastic parts with special shapes, and its adaptability to products is not high. This device limits its own application range and affects production efficiency and cost-effectiveness. In order to solve the above problems, a painting production line jig with high adaptability is proposed now. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems and provide a painting production line jig with high adaptability.

[0005] The specific scheme of the utility model is: a painting production line jig with high adaptability, which includes mounting plate I, lead screw, mounting plate II, hinge plate, mounting block, support rod and rubber clamping block. A lead screw is connected to mounting plate I, and the top of the lead screw is connected to mounting plate II. Hinge plates are symmetrically hinged on mounting plate II. Mounting blocks are connected to the ends of the hinge plates far away from mounting plate II. Friction dampers are arranged between the hinge plates and mounting plate II. Support rods are connected to the mounting blocks, and four rubber clamping blocks are connected to the upper ends of the support rods.

[0006] Further, it also includes rubber suction cups, and rubber suction cups are symmetrically and rotatably connected to the upper parts of the support rods.

[0020] Please refer to Figures 1 - 3 , a painting production line fixture with high adaptability, as Figures 1 - 3 shown, which includes mounting plate I 1, lead screw 2, mounting plate II 3, hinged plate 4, mounting block 5, support rod 6 and rubber clamping block 8. The middle of mounting plate I 1 is connected with lead screw 2, the top of lead screw 2 is connected with mounting plate II 3. Hinged plates 4 are symmetrically hinged on the left and right of mounting plate II 3. The ends of hinged plates 4 far from mounting plate II 3 are both connected with mounting blocks 5. Friction dampers are arranged between hinged plates 4 and mounting plate II 3. Support rods 6 are fixedly connected to mounting blocks 5. Four rubber clamping blocks 8 are connected to the upper ends of support rods 6. Slopes are arranged on the sides where rubber clamping blocks 8 contact each other.

[0021] It also includes a rubber suction cup 9, a sliding ring 7, an adjusting cylinder 10, a pull rope 11, a guide rail 12, a cover plate 13 and a rubber strip 14. The upper parts of the support rods 6 are symmetrically and rotatably connected with rubber suction cups 9 through rotating shafts. The rubber suction cups 9 are designed in an inclined plane shape, optimizing the fitting degree and adsorption performance with the product surface; an adjusting cylinder 10 is threadedly connected to the lead screw 2, and pull ropes 11 are symmetrically connected to the left and right of the adjusting cylinder 10. The ends of the pull ropes 11 that are not connected to the adjusting cylinder 10 are respectively connected to the mounting blocks 5 close to themselves. Guide rails 12 are symmetrically connected to the left and right on the mounting plate II 3, and sliding rings 7 are slidably connected to the left and right on the guide rails 12; a cover plate 13 is connected to the top of the mounting plate II 3; two rubber strips 14 are symmetrically connected to the front and back on the cover plate 13.

[0022] When using this device, first, fix this device on the spray painting production line through mounting plate I 1. Then, insert the product to be fixedly clamped into rubber clamping block 8. Due to its soft characteristics, rubber clamping block 8 can effectively clamp the product, enabling the four rubber clamping blocks 8 on support rod 6 to adapt to products of different shapes and clamp them, effectively improving the adaptability and utilization rate of this device. When spray painting and clamping a product with an arc-shaped interior, rotate rubber suction cup 9 to adjust it to an angle that can fit the interior of the product, and then cover the product on rubber suction cup 9. At this time, rubber suction cup 9 will closely fit the interior of the product and adsorb it, thus stably fixing the product. When adjusting the distance between support rods 6, rotate adjusting cylinder 10 clockwise. Adjusting cylinder 10 will move downward along lead screw 2. At the same time, pull rope 11 will be pulled to rotate together and wind around adjusting cylinder 10. While pull rope 11 winds around adjusting cylinder 10, it will pull the end of articulated plate 4 and mounting block 5 downward. When articulated plate 4 is pulled downward, it will drive support rod 6 and the components mounted on support rod 6 to move downward together. At this time, support rod 6 will slide downward within sliding ring 7. Since the distance between articulated plate 4 and the middle of guide rail 12 will gradually shorten as articulated plate 4 moves downward, at this time, support rod 6 will move toward the middle of guide rail 12. When support rod 6 moves inward, rubber strip 14 is compressed and deformed, and then rubber strip 14 naturally adheres to both sides of support rod 6 to ensure the sealing effect. While support rod 6 moves toward the middle, sliding ring 7 will also be driven to move toward the middle of guide rail 12 together, thereby shortening the distance between support rods 6. When adjusting support rod 6 to the desired distance, stop rotating adjusting cylinder 10. When increasing the distance between support rods 6, rotate adjusting cylinder 10 counterclockwise. Adjusting cylinder 10 will move upward along lead screw 2, and pull rope 11 will gradually unwind from adjusting cylinder 10. At this time, the pulling force of pull rope 11 on articulated plate 4 gradually decreases, and the operator manually moves articulated plate 4 upward to make articulated plate 4 reset upward, thereby gradually increasing the distance between support rods 6. When adjusting support rod 6 to the desired distance, stop rotating adjusting cylinder 10, realizing that the distance between support rods 6 can be adjusted, enabling this device to adjust the distance between support rods 6 according to the size of the product to be spray painted, thus extremely effectively improving the adaptability and utilization rate of this device. Cover plate 13 and rubber strip 14 can effectively prevent paint from being sprayed and accumulated inside the device during spray painting, thus affecting the normal operation of the device.

[0023] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
