Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a stamping feeding and positioning device for thin-walled automotive components, comprising a mounting bracket 1 and a mounting frame 4. Two sets of first connecting rods 2 are slidably connected inside the mounting bracket 1. The first connecting rods 2 have lugs 7 fixedly welded to one side facing each other. An outer fixing plate 8 is fixedly welded between the lugs 7 on the same side. An extension plate 9 is fixedly welded to one side of the outer fixing plate 8. Sliding rods 10 are slidably connected inside both sides of the outer fixing plate 8. An inner fixing plate 13 is fixedly welded to one side of the sliding rod 10. An extension hole 14 facing the extension plate 9 is opened inside the inner fixing plate 13. A fixing piece 11 is fixedly welded to the other end of the sliding rod 10. A spring 12 is fixedly welded between the fixed plate 11 and the outer fixed plate 8. The spring 12 is sleeved on the outside of the sliding rod 10. When the workpiece is conveyed to the inner fixed plate 13, the inner fixed plate 13 limits the thin-walled component. The sliding rod 10 continues to drive the outer fixed plate 8. The outer fixed plate 8 moves along the sliding rod 10, so that the extension plate 9 penetrates the extension hole 14 and stably limits the thin-walled component. When the inner fixed plate 13 and the extension plate 9 are separated from the thin-walled component, the spring force of the spring 12 is small enough to prevent the pressure between the inner fixed plate 13 and the thin-walled component from being too large and affecting the normal conveying of the thin-walled component. The spring 12 rebounds and causes the extension plate 9 to be separated from the extension hole 14. Two sets of infrared detectors 15 are fixedly welded to both sides of the outer fixing plate 8. Two sets of grooves 16 that cooperate with the infrared detectors 15 are opened on one side of the inner fixing plate 13. When the infrared detectors 15 enter the grooves 16, it proves that the extension plate 9 has entered the extension hole 14 and is fixed to both sides of the thin-walled component, and then the movement of the outer fixing plate 8 is stopped. On the same side, the first connecting rod 2 penetrates the mounting frame 4 and is fixedly welded to the first connecting plate 3. The outer flange of the mounting frame 4 is equipped with the first motor 5. The power end of the first motor 5 penetrates the mounting frame 4 and is connected to the first threaded rod 6 via a coupling. The tail of the first threaded rod 6 is rotatably connected to the inner wall of the mounting frame 4. The first threaded rod 6 is threadedly connected to the inside of the first connecting plate 3. According to the size of the thin-walled component to be processed, the first motor 5 is started, and the first threaded rod 6 rotates to drive the first connecting plate 3 to move laterally. The distance between the two sets of inner fixing plates 13 is adjusted by the first connecting rod 2 and the lug 7 so that the inner fixing plates 13 and the extension plate 9 on both sides fix the two sides of the thin-walled component. Several sets of transport rollers 17 are rotatably connected at the lower part of the mounting frame 1. A second motor 18 is installed on a flange on one side of the mounting frame 1. The power end of the second motor 18 is connected to the first set of transport rollers 17 via a coupling. Rotating rods 19 are fixedly welded to both sides of the transport rollers 17. Transmission belts 20 are staggered on the outer side of the rotating rods 19. When the thin-walled component is placed on the transport rollers 17, the second motor 18 is started. Power is transmitted to all the transport rollers 17 through the rotating rods 19 and the transmission belts 20. The workpiece is conveyed forward with the transport rollers 17. A connecting frame 21 is fixedly welded to the lower part of the mounting frame 4. An extension frame 22 is fixedly welded to the lower part of the mounting frame 1. Two sets of second connecting rods 23 are fixedly welded between the lower parts of the two connecting frames 21. A second connecting plate 24 is fixedly welded to the middle of the second connecting rod 23. A second threaded rod 26 is threadedly connected to the middle of the second connecting plate 24. One end of the second threaded rod 26 is rotatably connected to one side of the extension frame 22. A third motor 25 is installed on the flange of the other side of the extension frame 22. The power end of the third motor 25 is connected to the second threaded rod 26 via a coupling. When the third motor 25 is started, the second threaded rod 26 rotates, driving the second connecting plate 24 to move longitudinally. The overall longitudinal position of the positioning mechanism is adjusted through the connecting frame 21 until it is aligned with the stamping station. A curved frame 27 is provided on the lower middle part of the connecting frame 21, facing the third motor 25, to prevent the connecting frame 21 from colliding with the third motor 25.

[0016] Working principle: When using this utility model, according to the size of the thin-walled component to be processed, the first motor 5 is started, the first threaded rod 6 rotates and drives the first connecting plate 3 to move laterally. The distance between the two sets of inner fixing plates 13 is adjusted by the first connecting rod 2 and the lug 7. The inner fixing plate 13 limits the thin-walled component. The sliding rod 10 continues to drive the outer fixing plate 8. The outer fixing plate 8 moves along the sliding rod 10, so that the extension plate 9 penetrates the extension hole 14 and stably limits the thin-walled component. The third motor 25 is started, the second threaded rod 26 rotates and drives the second connecting plate 24 to move longitudinally. The longitudinal position of the positioning mechanism is adjusted by the connecting frame 21 until it is aligned with the stamping station. The thin-walled component is placed on the transport roller 17. The second motor 18 is started, and the power is transmitted to all transport rollers 17 through the rotating rod 19 and the transmission belt 20. The workpiece is conveyed forward with the transport roller 17.
