The conveying mechanisms are used to clamp, convey and flip the metal castings. When the two conveying mechanisms move at the same time, the metal castings can be conveyed; when only one of the conveying mechanisms moves, the metal castings can be flipped; a lifting mechanism 4 is provided on the two conveying mechanisms. Between the mechanisms, during the flipping of the casting, the lifting mechanism 4 is used to lift the casting to cooperate with the flipping of the casting; two driving mechanisms 3, one driving mechanism 3 is used to drive the upper conveying mechanism on the two clamping frames 2 to move simultaneously, and the other driving mechanism 3 is used to drive the lower conveying mechanism of the two clamping frames 2 to move simultaneously; a servo motor 6 is fixedly installed on the fixed frame 1, and a double-headed screw rod 7 is fixedly connected to the rotating shaft of the servo motor 6, which is used to drive the two clamping frames 2 to move in different directions respectively. The surface of the double-headed screw rod 7 is provided with thread lines in opposite directions, and the double-headed screw rod 7 is threadedly connected to the clamping frame 2.

[0024] like Figure 3 As shown, the conveying mechanism includes a conveyor belt 23 and a conveyor wheel 21. A pair of conveyor wheels 21 are provided, and the conveyor wheels 21 and the conveyor belt 23 are in transmission cooperation; the clamping frame 2 is connected to a pressing frame 24 corresponding to the conveying mechanism one by one, and the pressing frame 24 is parallel to the conveyor belt 23 and is arranged in the inner layer of the conveyor belt 23. The pressing frame 24 is connected to a plurality of pressing wheels 25 along its length direction. The pressing wheels 25 are in contact with the inner surface of the conveyor belt 23. The conveyor belt 23 is supported by the pressing wheels 25 so that the conveyor belt 23 can be clamped and fixed to the casting. The pressing frame 24 is fixed A screw rod 26 is connected, and the screw rod 26 is fixedly connected to the clamping frame 2 by a nut. The screw rod 26 can adjust the pressing effect of the pressure wheel 25 on the conveyor belt 23; when the casting is conveyed between the two clamping frames 2, the two clamping frames 2 are driven close to each other, and the conveyor belt 23 contacts the surface of the casting, clamping the casting; when only the upper conveyor belt 23 moves and the lower conveyor belt 23 is stationary, the casting can be driven to flip forward; similarly, when only the lower conveyor belt 23 moves and the upper conveyor belt 23 is stationary, the casting can be driven to flip backward.

[0025] like Figure 4-Figure 5As shown, the driving mechanism 3 includes a pair of connecting frames 31, the connecting frame 31 is fixedly connected to the fixed frame 1, a rotating shaft 33 is rotatably connected between the two connecting frames 31, and a driving motor 32 is installed at one end of the rotating shaft 33.

When the clamping frame 2 moves, it can drive the sliding sleeve 35 to slide on the surface of the rotating shaft 33, so that the driving bevel gear 36 and the driven bevel gear 22 always keep in meshing. When the rotating shaft 33 rotates, it drives the driving bevel gear 36 to rotate. When the driving bevel gear 36 rotates, it drives the driven bevel gear 22 to rotate, thereby driving the conveying wheel 21 and the conveyor belt 23 to rotate, thereby controlling the conveying or flipping of the casting.

[0026] like Figure 6 As shown, the lifting mechanism 4 includes: a mounting frame 41, which is fixedly connected to the fixing frame 1; a lifting cylinder 42, which is fixedly mounted on the mounting frame 41, a lifting frame 43 is fixedly connected to the lifting cylinder 42, and a bogie 47 is rotatably connected to the lifting frame 43; a rotatable support plate 48 is connected to the bogie 47, and the support plate 48 is used to support the casting during the flipping process and assist in the flipping of the casting.

[0027] Working principle: When the assembly line conveys the casting between the two clamping frames 2, the upper and lower conveyor belts 23 move at the same time to move the casting to the position above the lifting mechanism 4, and then the driving mechanism 3 controls the movement of the conveyor belt 23 of one layer, thereby rotating the casting to an inclined state, and then the lifting cylinder 42 drives the support plate 48 to rise, and at the same time adjusts the angle of the support plate 48 through the telescopic mechanism 49 so that the support plate 48 can contact a larger area of ​​the bottom surface of the casting. As the support plate 48 rises, the support plate 48 rotates to a horizontal state, thereby assisting the complete flipping of the casting, and then the two clamping frames 2 move away from each other, and the casting is adjusted to the specified direction by the rotation of the bogie 47 to complete the flipping and turning of the casting. Finally, the two clamping frames 2 approach to clamp the casting again, and the upper and lower conveyor belts 23 move at the same time to convey the casting to the next assembly line.
