Description

Technical Field

[0001] The present invention belongs to the field of electric manufacturing, and in particular relates to an intelligent running-in assembly device for a slip ring. Background Art

[0002] Slip rings are the electrical connection between the fixed and rotating parts of a radar and are a key component in various radar drive systems. Power slip rings are primarily responsible for high-power electrical energy transmission. Power slip rings in large radars are mostly cylindrical slip rings, combining a ring core and brushes. To reduce the current density at the contact surface between the brush and the conductive ring of the ring core and prevent brush vibration during ring core rotation, the contact surface between the brush and the conductive ring is typically run-in for a period of time before installation to ensure maximum contact between the brush contacts on the ring core and the conductive ring surface.

[0003] Because the brush material is highly wear-resistant, in order to shorten the running-in cycle and improve running-in efficiency, the brush's R arc is generally rough-ground before fine-grinding. Otherwise, the required reliable contact area between the brush and the conductive block on the ring core will be difficult to achieve. Before assembly, the brush R arc is rough-ground, and the ring core is not assembled with cables. A running-in method using a dedicated grinding core or sandpaper attached to the surface of the conductive ring is used. After rough grinding, the brush and ring core must be removed and cleaned with aviation gasoline. After cleaning, the cables on the conductive ring are connected, the conductive ring is assembled, and the brush assembly is installed in the entire machine. The brush and conductive ring on the complete bus ring are fine-ground to match.

[0004] Current running-in devices typically utilize a rotating ring core and fixed brushes. Since the ring core is not connected to cables during rough grinding, this generally meets the requirements of rough grinding. However, during fine grinding, multiple cables over 1 meter in length are drawn from the ring core, making traditional equipment unable to rotate with the cables. Currently, manual fine grinding and running-in are commonly performed, resulting in low fine grinding efficiency, high operator labor intensity, difficulty in controlling quality, and poor consistency. Furthermore, traditional running-in devices can only input control commands via keystrokes, and these commands cannot cycle through forward and reverse rotation, making operation inconvenient. Traditional running-in devices also fail to record run-in data and fault alarms, hindering quality traceability.

[0005] Therefore, how to provide a running-in assembly device that can intelligently control and automatically record running-in parameters and can automatically replace manual operation to achieve fine grinding and rough grinding of the slip ring brush and ring core is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention
