Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a permanent magnet rotor surface cleaning device. Background Technology

[0002] Permanent magnet motors are one of the key factors determining the driving stability of new energy vehicles. Therefore, it is very important to ensure the reliability of motor operation and reduce the failure rate of permanent magnet motors. In order to improve the reliability of motor operation, in addition to improving the motor itself, it is also necessary to impose higher requirements on the cleanliness of the surface of the permanent magnet rotor body, especially that there should be no dust, metal shavings or other debris on the surface.

[0003] Current mass production processes for permanent magnet rotors generally suffer from cleaning defects: most manufacturers still use non-standardized cleaning or manual tape bonding methods, resulting in unstable cleaning quality and low efficiency, making it difficult to meet the needs of large-scale production, and significantly increasing the quality risks of motor operation.

[0004] Therefore, it is essential to provide a permanent magnet rotor surface cleaning device to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a permanent magnet rotor surface cleaning device. In this invention, the permanent magnet rotor body is driven to rotate by motor B. The cleaning mechanism adjusts its position through vertical and horizontal telescopic rods to adapt to permanent magnet rotor bodies of different diameters and lengths. Motor A drives the gear to rotate, which in turn drives four external gear rings to rotate synchronously. The gear and external gear ring transmission structure enables multiple brushes to work synchronously and evenly, improving cleaning efficiency. At the same time, the brushes at the bottom of the annular plate, which form a wave-shaped distribution, scrape the surface of the permanent magnet rotor body. Simultaneously, the suction unit adsorbs the removed impurities. The brushes and suction components work together to effectively remove stubborn impurities. After cleaning, the vertical and horizontal telescopic rods are reset for easy replacement of the workpiece.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A permanent magnet rotor surface cleaning device is provided, including a permanent magnet rotor body, a rotating mechanism installed at the end of the permanent magnet rotor body, and a cleaning mechanism movably abutting against the outer side of the permanent magnet rotor body.

[0008] Specifically, the cleaning mechanism includes a support base, a vertical telescopic rod installed on the top of the support base, a horizontal telescopic rod installed at the top of the vertical telescopic rod, a motor A vertically installed at the end of the horizontal telescopic rod, a gear connected to the motor A for axial transmission, and four external gear rings installed at equal angles on the outer ring of the gear.

[0009] Furthermore, each external gear ring is movably mounted with a support plate via a bearing, and the four support plates are collectively mounted on an annular support frame. The four support plates are equally distributed and mounted on the annular support frame, and the annular support frame is fixedly mounted to the end of the transverse telescopic rod. A suction assembly is mounted on the lower end face of each external gear ring.

[0010] The rotating mechanism includes support column A and support column B. Support column A is movably mounted on one end of the permanent magnet rotor body via bearings. Motor B is axially driven and mounted on the other end of the permanent magnet rotor body. Motor B is fixedly mounted on the top of support column B.

[0011] The suction assembly includes a suction machine body, which is mounted on the lower end face of the outer gear ring. An annular plate is installed on the outer side of the suction end of the suction machine body. Several brushes are installed at equal angles on the bottom end face of the annular plate. The bottom ends of the brushes are staggered in a wave-like pattern. The brushes move in contact with the outside of the permanent magnet rotor body.

[0012] In this invention, the permanent magnet rotor body is driven to rotate by motor B. The cleaning mechanism adjusts its position through vertical and horizontal telescopic rods to accommodate permanent magnet rotor bodies of different diameters and lengths. Motor A drives the gear to rotate, which in turn drives the four external gear rings to rotate synchronously. The gear and external gear ring transmission structure enables multiple brushes to work synchronously and evenly, improving cleaning efficiency. At the same time, the brushes at the bottom of the annular plate, which form a wave-shaped distribution, scrape the surface of the permanent magnet rotor body. Meanwhile, the suction unit adsorbs the removed impurities. The brushes and suction components work together to effectively remove stubborn impurities. After cleaning, the vertical and horizontal telescopic rods are reset for easy replacement of the workpiece. Attached Figure Description

The bottom ends of the brushes 18 are staggered in a wave pattern. The brushes 18 are in active contact with the outside of the permanent magnet rotor body 1.

[0042] The purpose of this utility model is to provide a permanent magnet rotor surface cleaning device, which achieves all-round and efficient cleaning of the rotor surface through the coordinated operation of the multi-degree-of-freedom adjustable cleaning mechanism 3 and the rotating mechanism 2, and is compatible with permanent magnet rotors of different sizes and specifications.

At the same time, the brushes 18 at the bottom of the annular plate 17, which form a wave-shaped distribution, scrape the surface of the permanent magnet rotor body 1. Meanwhile, the suction machine body 16 adsorbs the removed impurities. The brushes 18 and the suction assembly 12 work together to effectively remove stubborn impurities.
