[0021] 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.

[0022] like Figures 1-6 As shown, a conveying device for cast wheel hub blanks includes a frame 1. Two slide rails 2 are mounted on the frame 1, arranged parallel to each other and along the left-right direction. A slider 3 slides on the slide rails 2, and a gantry 4 is mounted on the slider 3. Slide rails 6 are mounted vertically on the inner sides of the front and rear side walls of the gantry 4, and sliders 7 slide on the slide rails 6. A lifting plate 8 is installed inside the slider 7. A support plate 30 and a connecting plate 9 connect the two lifting plates 8, with the connecting plate 9 located above the support plate 30. A lifting mechanism 5 is mounted on the top of the gantry 4, and the lifting mechanism 5 is connected to the connecting plate 9. A slide rail 31 is mounted on the upper part of the support plate 30, arranged along the front-back direction. A slider 32 slides on the slide rail 31, and a clamping mechanism 10 is mounted on the upper part of the slider 32. A pushing mechanism 27 is mounted on the rear lifting plate 8, and the pushing mechanism 27 is connected to the clamping mechanism 10. The lifting mechanism 5 and the pushing mechanism 27 are cylinders, hydraulic rods, or electric push rods. The lifting mechanism 5 can drive the connecting plate 9 to move up and down, thereby driving the clamping mechanism 10 to move up and down. The pushing mechanism 27 can drive the clamping mechanism 10 to move back and forth.

[0023] like Figure 1 , Figure 6As shown, a rack 11 is mounted on the frame 1, parallel to the slide rail 2. A drive motor 12 is mounted on the side of the gantry 4, and a drive gear 13 is connected to the drive motor 12, meshing with the rack 11. The drive motor 12 drives the drive gear 13 to rotate, and the drive gear 13 meshes with the rack 11, thus moving the gantry 4 along the slide rail 2. Photoelectric sensors 44 are mounted on the frame 1 at positions corresponding to both ends of the rack 11. Two detection plates 45 are mounted on the side wall of the gantry 4, and the photoelectric sensors 44 are electrically connected to the drive motor 12. When the detection plate 45 moves into the sensing area of ​​the photoelectric sensor 44, the light path of the photoelectric sensor is blocked, and a stop signal is sent to the drive motor 12. Through the cooperation of the two detection plates 45 and the photoelectric sensors 44 on both sides, the drive motor 12 can be controlled to stop running, thereby limiting the extreme positions of the gantry 4.

[0024] like Figures 3-5 As shown, the clamping mechanism 10 includes a support arm 28, on which two clamping members 29 are mounted. The two clamping members 29 can be relatively far apart to release the blank or relatively close together to clamp the blank. Mounting grooves 33 are provided on both the front and rear sides of the support arm 28. A slide rail 34 is installed in the mounting groove 33, and a slider 35 is slidably mounted on the slide rail 34. The clamping member 29 includes a mounting plate 36. A through hole 37 is provided in the middle of the support arm 28, connecting the front and rear mounting grooves 33. The mounting plate 36 passes through the through hole 37 to be mounted on the front and rear sliders 35. Mounting blocks 38 are mounted on both the front and rear sides of the mounting plate 36. Mounting rods 39 pass through the mounting blocks 38. A claw 40 is welded to the bottom of the mounting rod 39. The inner side of the claw 40 is arc-shaped to match the shape of the wheel hub blank. A rack 42 is connected to the mounting plate 36, and a transmission gear 43 is rotatably mounted on the support arm 28. The racks 42 of the two clamping members 29 are located on the front and rear sides of the transmission gear 43, respectively, and both racks 42 mesh with the transmission gear 43. A drive mechanism 41 is mounted on the support arm 28, and the drive mechanism 41 is connected to one of the mounting plates 36. The drive mechanism 41 drives one of the mounting plates 36 to move, and the racks 42 on the mounting plate 36 act on the transmission gear 43 to make it rotate. The transmission gear 43 then acts on the other rack 42 to make it move, thereby driving the other mounting plate 36 to move in the opposite direction, so that the two clamping members 29 can move away from or closer to each other.

[0025] like Figure 1 , Figure 3As shown, a support platform 15 is mounted on the frame 1 via a moving mechanism. The moving mechanism includes a mounting frame 14, on which two slide rails 16 are mounted. The slide rails 16 are oriented in the same direction as slide rail 2. Two sliders 17 are slidably mounted on slide rails 16. A cross plate 18 is mounted on the two opposing sliders 17. A connecting frame 20 connects the two cross plates 18. A support rod 19 passes through the cross plate 18, and the upper end of the support rod 19 is connected to the bottom surface of the support platform 15. The moving mechanism also includes a drive motor 23, a drive sprocket 24, and a driven sprocket 25. The drive motor 23 is driven by the drive sprocket 24. A chain 26 is provided between the drive sprocket 24 and the driven sprocket 25. A connector 22 is connected to the bottom of the connecting frame 20, and the chain 26 is connected to the connector 22. The drive motor 23 drives the drive sprocket 24 to rotate, thereby pulling the connector 22 via the chain 26, thus moving the support platform 15.

[0026] Inductive sensors 46 are installed on the frame 1 at positions corresponding to both ends of the slide rail 16. The inductive sensors 46 are electrically connected to the drive motor 23. The two inductive sensors 46 cooperate with the two horizontal plates 18 respectively. When the horizontal plate 18 moves above the corresponding inductive sensor 46, the inductive sensor 46 sends a signal to the drive motor 23, causing the drive motor 23 to stop running, thereby limiting the movement of the support platform 15.

[0027] A spring 21 is fitted on the support rod 19. The spring 21 is located between the horizontal plate 18 and the support platform 15. When the blank is placed on the support platform 15, the spring 21 absorbs the impact energy through elastic deformation, reduces the impact force between the blank and the support platform 15, and prevents the blank from deforming.

[0028] The blank movement adopts a double-layer movement design, which replaces the worker's hand-held clamp to remove the casting blank, reducing labor intensity and ensuring worker safety.

[0029] In practical use, the clamping component 29 is located outside the casting machine, leaving space for the casting machine to lift the upper mold. The drive motor 12 drives the drive gear 13 to rotate, causing the gantry 4 to move and drive the support arm 28 and the clamping component 29, so that the clamping component 29 moves directly above the blank. The forward stroke of the gantry 4 can reach 1000mm, and the moving speed is 6mm / s.

[0030] At the start of each action, the support platform 15 is reset to prepare for the subsequent delivery of the blank. The maximum travel of the support platform 15 on the slide rail 16 is 1000mm, which is driven by the moving mechanism.

[0031] The lifting mechanism 5 lowers the transmission connecting plate 9, which drives the clamping mechanism 10 to a suitable position. The maximum lifting stroke of the clamping mechanism 10 is 500mm.

[0032] The drive mechanism 41 drives one of the clamping members 29 to move toward the other clamping member 29, and the other clamping member 29 moves synchronously, bringing the two clamping members 29 closer together. The two clamping members 29 retract inward to clamp the blank. Based on the shape characteristics of the wheel hub blank, the inner side of the clamping member 29 is designed to be arc-shaped, which can better fit the outer circumference of the wheel hub for clamping.

[0033] After the clamping component 29 clamps the blank, the lifting mechanism 5 drives the support arm 28 to rise and remove the blank from the mold.

[0034] The gantry 4 moves away from the casting machine, causing the blank to move. Compared to the initial state, the maximum backward stroke of the gantry 4 is 800mm.

[0035] The gantry 4 carries the blank to above the support platform 15. The lifting mechanism 5 drives the support arm 28 to descend, thereby lowering the blank. After the lower end of the blank is 5-10mm away from the end face of the support platform 15, the two clamping parts 29 separate and release, and the blank falls onto the support platform 15.

[0036] The moving mechanism drives the support platform 15 to move, transporting the blank to the other end. The support platform 15 stays at this end for a period of time, allowing the blank to cool further while also giving the workers more time to operate.

[0037] The gantry 4 resets, returning to its initial state, and the entire process ends.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
