[0002] As a rotating component of an electric motor, the rotor enables the conversion between electrical energy and mechanical energy, and vice versa. During the manufacturing process, the rotor requires aluminum casting. CN201310751679.3 describes an aluminum casting device for an electric motor rotor, comprising a clamping base with two rotor core clamping parts for holding the rotor core. The two rotor core clamping parts are symmetrically arranged to clamp the sides and bottom of the rotor core. Above the rotor core clamping parts is a guide flared opening for guiding molten aluminum into the rotor core. This invention has the advantages of simple structure and convenient operation. However, in the above technical solution, during the aluminum casting process, when the rotor assembly comes into contact with the molten aluminum, the molten aluminum may splash. Without protection, the molten aluminum may come into contact with workers, leading to a safety accident. Utility Model Content

[0003] The main purpose of this utility model is to provide a device for casting aluminum on the surface of a motor rotor, which can effectively solve the problem in the background art where, during the process of casting aluminum on a rotor, the molten aluminum may splash when the rotor comes into contact with the molten aluminum. Without protection, the molten aluminum may come into contact with workers, causing safety accidents.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a device for casting aluminum on the surface of a motor rotor, comprising a processing table, a sliding rod slidably mounted on the processing table, a support plate fixedly mounted on the upper end of the sliding rod, an upper die head mounted on the lower surface of the support plate, an installation groove formed on the upper surface of the processing table, a servo motor fixedly mounted on the inner surface of the installation groove, a plurality of connecting rods equidistantly fixedly mounted on the circumference of the output end of the servo motor, a clamping ring mounted at the top of each connecting rod, an aluminum liquid tank formed on the upper surface of the processing table, the aluminum liquid tank being located directly below the upper die head, and a drive protection assembly provided on the upper surface of the processing table.

[0005] Preferably, a plurality of support rods are fixedly installed at equal intervals on the lower surface of the processing table, and a support plate is fixedly installed between the lower ends of the plurality of support rods.

[0006] Preferably, a return spring is fixedly installed on the upper surface of the support plate, and the upper end of the return spring is disposed on the lower end surface of the slide rod.

[0007] Preferably, each of the clamping rings has a guide groove on its circumferential surface, a guide block is slidably installed on the inner surface of the guide groove, and the top end of the connecting rod is disposed on the surface of the guide block.

[0008] Preferably, the drive protection component includes a mounting rod and a through slot, wherein the mounting rod is fixedly mounted on the upper surface of the machining table, and the through slot is formed on the upper surface of the machining table.

[0009] Preferably, a top plate is fixedly installed on the upper end of the mounting rod, a hydraulic cylinder is fixedly installed on the lower surface of the top plate, and a protective cylinder is installed on the output end of the hydraulic cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The hydraulic cylinder extends and retracts at the output end, which drives the protective cylinder to move downward, so that the protective cylinder is fitted around the circumference of the rotor assembly and plays a protective role.

A support plate 6 is fixedly mounted on the upper end of the sliding rod 5. An upper die head 7 is mounted on the lower surface of the support plate 6. An installation groove 9 is formed on the upper surface of the processing table 1. A servo motor 10 is fixedly mounted on the inner surface of the installation groove 9. Several connecting rods 11 are fixedly mounted at equal intervals on the circumference of the output end of the servo motor 10. A clamping ring 12 is installed at the top of each connecting rod 11. An aluminum liquid tank 13 is formed on the upper surface of the processing table 1. The aluminum liquid tank 13 is located directly below the upper die head 7. A drive protection component 8 is provided on the upper surface of the processing table 1.

[0021] like Figure 1 As shown, a number of support rods 2 are fixedly installed at equal intervals on the lower surface of the processing table 1, and a support plate 3 is fixedly installed between the lower ends of the support rods 2, which can support the processing table 1.

[0022] like Figure 2 , 3As shown in Figure 4, a return spring 4 is fixedly installed on the upper surface of the support plate 3. The upper end of the return spring 4 is set on the lower end surface of the slide rod 5. Each clamping ring 12 has a guide groove 14 on its circumference. A guide block 15 is slidably installed on the inner surface of the guide groove 14. The top end of the connecting rod 11 is set on the surface of the guide block 15. The drive protection assembly 8 includes a mounting rod 801 and a through groove 807. The mounting rod 801 is fixedly installed on the upper surface of the processing table 1. The through groove 807 is opened on the upper surface of the processing table 1. A top plate 802 is fixedly installed on the upper end of the mounting rod 801. A hydraulic cylinder 803 is fixedly installed on the lower surface of the top plate 802. A protective cylinder 804 is installed on the output end of the hydraulic cylinder 803. The protective cylinder 804 slides through the support plate 6. The protective cylinder 804 is set inside the through groove 807. A slot 805 is opened on the circumference of the protective cylinder 804. A sliding plate 806 is slidably installed through the inner wall of the slot 805. The output end of the hydraulic cylinder 803... When the hydraulic cylinder 803 extends and retracts, it drives the protective cylinder 804 to move downwards, so that the protective cylinder 804 is fitted around the circumference of the rotor assembly, providing protection. When the hydraulic cylinder 803 continues to move downwards, and the top of the protective cylinder 804 contacts the support plate 6, it drives the support plate 6 to move downwards, so that the upper die head 7 contacts the rotor assembly, pressing the rotor assembly into the aluminum liquid tank 13 for aluminum casting. During the processing, the protective cylinder 804 will fit the rotor assembly inside the sealed space. In the event of splashing of aluminum liquid during aluminum casting, the protective cylinder 804 will block it, avoiding safety accidents and improving the safety performance of the device.

This device is also equipped with several tooling fixtures, which facilitates the processing of the parts by the workers and improves the efficiency of the device.

[0023] The working principle of this type of aluminum-casting device on the surface of a motor rotor:

[0024] In use, when this device is needed to cast aluminum for the motor rotor, the rotor assembly is positioned at the clamping ring 12, and molten aluminum is placed inside the molten aluminum tank 13. The connecting rod 11 is then driven by the output of the servo motor 10 to swing, rotating the rotor assembly to the position of the molten aluminum tank 13. The hydraulic cylinder 803 then extends and retracts, driving the protective cylinder 804 downwards. The protective cylinder 804 is then fitted around the circumference of the rotor assembly, providing protection. As the hydraulic cylinder 803 continues to move downwards, when the top of the protective cylinder 804 contacts the support plate 6, the support plate 6 is driven to move downwards. The upper die head 7 contacts the rotor assembly, pressing the rotor assembly into the aluminum molten tank 13 for aluminum casting. During processing, the protective cylinder 804 encloses the rotor assembly in a sealed space. In case of splashing of molten aluminum during casting, the protective cylinder 804 will prevent accidents and improve the safety performance of the device. After processing, the protective cylinder 804 resets, and the return spring 4 resets the slide bar 5, which in turn resets the upper die head 7. The device is equipped with several tooling fixtures, which facilitates the processing of parts by the operator and improves the efficiency of the device.
