DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-3 As shown, a rotatable die-casting machine receiving device includes a frame 1, and a tray 2 for receiving materials is rotatably connected to the frame 1. Specifically, the frame 1 includes a fixed plate 11 for fixing the receiving structure, and an axle seat 12 is connected to the fixed plate 11, and a rotating shaft 13 is rotatably connected to the axle seat 12, and an arm 3 for supporting the tray 2 is connected to the rotating shaft 13, and the tray 2 is fixedly connected to the arm 3, so that the tray 2 can be horizontally rotated by the arm 3 with the rotating shaft 13 as the axis.

[0022] After the wheel hub blank is cast and the die casting machine is demolded, the arm 3 drives the tray 2 to rotate horizontally with the rotating shaft 13 as the axis to the material receiving station, and the die casting machine drops the wheel hub blank on the tray 2. The arm 3 rotates horizontally to transfer the wheel hub blank on the tray 2 to the manipulator material taking station. This embodiment simplifies the structure of the material receiving device and reduces the failure rate.

[0023] Furthermore, a power device 4 is connected to the frame 1 to provide power for the rotation of the tray 2. The power device 4 is connected to the frame 1 through a power bracket 41, and a push rod 42 is telescopically connected to the front end of the power device 4. A connecting plate 43 is connected to the rotating shaft 13, and the push rod 42 is hinged to the connecting plate 43. When in use, the connecting plate 43 is displaced by the telescopic action of the push rod 42 of the power device 4, so that the rotating shaft 13 rotates, thereby forming a rotational power of the support arm 3 connected to the rotating shaft 13, driving the tray 2 to rotate horizontally to complete the material receiving or transportation action. The power device 4 can select conventional power configurations such as hydraulic cylinders, air cylinders or electric push rods 42. This embodiment realizes the automatic material receiving and transportation actions of the material receiving device, thereby improving the working efficiency.

[0024] As a preferred embodiment, in order to buffer the kinetic energy of the wheel hub blank falling onto the tray 2 and reduce the risk of wheel hub blank being damaged by collision, the tray 2 is elastically connected to the support arm 3 to avoid the rigid connection between the tray 2 and the support arm 3, so as to achieve smooth material connection. Specifically, a tray rack 5 is provided on the support arm 3 corresponding to the tray 2, the tray 2 is connected to the support arm 3 via the tray rack 5, and an elastic connector is provided between the tray 2 and the tray rack 5 to absorb the kinetic energy of the wheel hub blank during its falling process.

[0025] Preferably, if Figure 1 As shown, the elastic connector may be a support spring 51 disposed between the tray 2 and the tray frame 5, and the support spring 51 is disposed at the bottom of the tray 2 to elastically support the tray 2 on the tray frame 5. When receiving the material, the rapidly falling wheel hub blank consumes the falling kinetic energy by compressing the support spring 51, thereby achieving smooth material drop.

[0026] As another embodiment of the rotatable die casting machine receiving device, Figure 3 As shown, the elastic connector is a tension spring 52 circumferentially connected to the pallet 2. In this embodiment, the pallet frame 5 is an annular structure with an inner diameter greater than the diameter of the pallet 2, and the tension spring 52 is arranged between the outer diameter of the pallet 2 and the inner diameter of the pallet frame 5. In this embodiment, the tension spring 52 is arranged horizontally around the pallet 2, which reduces the overall height of the position of the pallet 2, so that the pallet 2 can complete the material receiving and transportation operations without interfering with the net-releasing operation of the net-releasing machine, thereby improving the operating efficiency. At the same time, the outer diameter of the pallet 2 extending in the horizontal direction increases the material receiving area of ​​the pallet 2, which can meet the material receiving requirements of larger-sized wheel slabs and improve the applicability.

[0027] Preferably, if Figure 1 As shown, in order to enhance the structural strength, two shaft seats 12 are provided corresponding to the rotating shafts 13 , and an angular contact bearing is provided inside the shaft seat 12 , and the rotating shaft 13 is rotatably connected to the shaft seat 12 via the angular contact bearing.

[0028] Preferably, reinforcing ribs are provided on the support arm 3 for reinforcing the structural strength of the support arm 3 , and the reinforcing ribs include a tie rib 61 connected between the upper part of the support arm 3 and the rotating shaft 13 , and also include a supporting rib 62 provided below the support arm 3 and connected to the rotating shaft 13 .

[0029] Preferably, in order to improve the automation of the material receiving device, a photoelectric sensor 7 is provided on the frame 1 corresponding to the tray 2 to monitor the material receiving state of the tray 2, and the photoelectric sensor 7 is communicatively connected to the power device 4. During the operation, the photoelectric sensor 7 monitors in real time whether the tray 2 is empty, which serves as a basis for determining whether the power device 4 drives the support arm 3 to move. This embodiment improves the automation of the material receiving device and ensures the safety of the operation.

[0030] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
