[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , Figure 4 and Figure 5 , an embodiment provided by the present invention: A positioning frame for processing automotive plastic door panels, including a base 1, a support shaft 2 fixedly connected to the top of the base 1, a turntable 3 fixedly connected to the top of the support shaft 2, a workbench 13 fixedly connected to the top of the turntable 3, two fixed frames 4 are arranged inside the workbench 13, a bidirectional telescopic rod 5 is fixedly connected to the adjacent side of the two fixed frames 4, push rods 6 are fixedly connected to the left and right sides of the bidirectional telescopic rod 5, first rotating shafts 7 are rotatably connected to the front and rear sides of the two push rods 6, the bottom ends of a plurality of first rotating shafts 7 are rotatably connected to connecting plates 8, one ends of a plurality of connecting plates 8 are rotatably connected to second rotating shafts 9, second rotating shafts 9 are fixedly connected to the tops of a plurality of slide blocks 10, limit blocks 16 are fixedly connected to the peripheries of a plurality of slide blocks 10, the size of the limit blocks 16 is larger than the size of the slide blocks 10, connecting columns 11 are fixedly connected to the tops of a plurality of slide blocks 10, clamping pieces 12 are fixedly connected to the tops of the connecting columns 11, a chute 17 is opened at the top of the workbench 13, and the connecting column 11 is slidably connected to the inside of the chute 17. A rotating mechanism 14 is arranged on the top of the base 1, and the rotating mechanism 14 is used to rotate the workbench 13 when the staff needs to process different positions of the automotive plastic door panel;

[0033] Specifically, when the positioner for processing automotive plastic door panels needs to position automotive plastic door panels of different sizes, first start the bidirectional telescopic rod 5. The bidirectional telescopic rod 5 drives the push rod 6 to move. The movement of the push rod 6 causes the first rotating shaft 7 to drive the connecting plate 8 to move. The connecting plate 8 drives the slider 10 to slide horizontally inside the fixed frame 4 through the second rotating shaft 9. The movement of the slider 10 causes the connecting column 11 fixedly connected to the slider 10 to move, thereby driving the clamping member 12 fixed to the connecting column 11 to move in the chute 17. The presence of the limit block 16 can prevent the slider 10 from falling off, so that the workbench 13 can clamp automotive plastic splints of different models, thus completing the positioning of automotive plastic door panels of different sizes. The model of the bidirectional telescopic rod 5 is JY-35;

[0034] Refer to Figure 1 , Figure 2 and Figure 4 , the rotating mechanism 14 includes two outer shells 1401. One end of each of the two outer shells 1401 is fixedly connected to the left and right sides of the base 1. A first spring 1402 is fixedly connected inside the two outer shells 1401. One end of each of the two first springs 1402 is fixedly connected to a bolt 1403. A second gear 1406 is fixedly connected to the outer wall of the support shaft 2. A first gear 1405 is meshed and connected to the left side of the second gear 1406. A stepping motor 1404 is fixedly connected to the bottom of the first gear 1405. The output end of the stepping motor 1404 is fixedly connected to the bottom of the first gear 1405. A motor bracket 19 is fixedly connected to the bottom of the stepping motor 1404. The bottom of the motor bracket 19 is fixedly connected to the top of the base 1. A plurality of screw holes 20 are formed in the outer wall of the turntable 3. The size of the screw holes 20 matches the size of the bolts 1403;

[0035] Specifically, when machining different positions of the automotive plastic door panel, pull the bolt 1403 to cause the first spring 1402 to undergo elastic deformation. The elastic deformation of the first spring 1402 allows the bolt 1403 to automatically rebound when needed. The bolt 1403 leaves the screw hole 20. The presence of the motor bracket 19 allows the stepping motor 1404 to be used in a suitable position. At this time, start the stepping motor 1404 to cause the stepping motor 1404 to drive the first gear 1405 to rotate. The first gear 1405 drives the meshed second gear 1406 to rotate, thereby driving the turntable 3 to rotate, so that the workbench 13 can rotate. When rotating to a suitable position, loosen the bolt 1403. The matching size of the bolt 1403 and the screw hole 20 enables the bolt 1403 to stably fix the workbench 13 and prevent further rotation, so that the staff can machine different positions of the automotive plastic door panel. The model of the stepping motor 1404 is 17HS13.

[0036] Refer toFigure 1 and Figure 3 One end of each of the plurality of sliders 10 is fixedly connected to a second spring 15, and the other ends of the plurality of second springs 15 are fixedly connected inside the fixed frame 4. A controller 18 is fixedly connected to the front side of the base 1, and the controller 18 is electrically connected to the stepping motor 1404;

[0037] Specifically, the second spring 15 can make the operation of the slider 10 more stable. The electrical connection between the controller 18 and the stepping motor 1404 enables the controller 18 to control the operation of the stepping motor 1404, making the rotation of the turntable 3 more stable.

[0038] Working principle: When the positioner for processing automotive plastic door panels needs to position automotive plastic door panels of different sizes, first start the bidirectional telescopic rod 5. The bidirectional telescopic rod 5 drives the push rod 6 to move. The movement of the push rod 6 causes the first rotating shaft 7 to drive the connecting plate 8 to move. The connecting plate 8 drives the slider 10 to slide horizontally inside the fixed frame 4 through the second rotating shaft 9. The movement of the slider 10 causes the connecting column 11 fixedly connected to the slider 10 to move, and then drives the clamping member 12 fixed on the connecting column 11 to move in the sliding groove 17, so that the workbench 13 can clamp automotive plastic splints of different models, and thus can complete the positioning of automotive plastic door panels of different sizes;

[0039] And when it is necessary to process different positions of the automotive plastic door panel, first pull the bolt 1403, causing the bolt 1403 to drive the first spring 1402 to undergo elastic deformation, so that the bolt 1403 leaves the screw hole 20. At this time, start the stepping motor 1404, so that the stepping motor 1404 drives the first gear 1405 to rotate. The first gear 1405 drives the second gear 1406 meshing with it to rotate, and then drives the turntable 3 to rotate, so that the workbench 13 can rotate. When it rotates to a suitable position, release the bolt 1403, so that the workbench 13 can be stably fixed and will no longer rotate, so that the staff can process different positions of the automotive plastic door panel.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
