Description

Technical Field

[0001] This utility model relates to the field of motor rotor oiling technology, specifically to an oiling device for motor rotors. Background Technology

[0002] A rotor is a rotating body supported by bearings. Objects such as optical discs that do not have their own axis of rotation can be regarded as a rotor when they are rigidly connected or have an additional shaft. An electric motor consists of two parts: a rotor and a stator. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy.

[0003] After a certain period of use, the surface of the motor rotor is prone to oxidation and rust, which affects normal use. It needs to be coated with oil for rust prevention and protection. Existing motor rotor oiling is mostly done manually. Large oiling equipment is costly and takes up a lot of space, making it inconvenient to quickly complete the oiling process of the motor rotor. In addition, some electronic rotors have severe surface rust, which requires grinding and rust removal before oiling. Existing oiling devices are not convenient to process different rotors according to their different needs. Therefore, an oiling device for motor rotors is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an oiling device for motor rotors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oiling device for motor rotors, comprising a bearing mechanism and an oiling mechanism;

[0006] The supporting mechanism includes a placement cylinder, a servo motor, and a connecting seat. The servo motor is installed at the bottom of the placement cylinder, and the output shaft of the servo motor passes through the placement cylinder. A connecting seat is fixedly connected to one side of the servo motor output shaft passing through the placement cylinder, and a base frame is fixedly connected to the bottom of the placement cylinder.

[0007] As a further preferred embodiment of this technical solution: the oiling mechanism includes a pull ring, a connecting rod, and an annular oil box;

[0008] The connecting rods are equidistantly distributed and fixedly connected to one side of the pull ring. A cover plate is provided on one side of the pull ring. The connecting rods pass through the cover plate, and one end of the connecting rods passing through the cover plate is fixedly connected to the annular oil box.

[0009] As a further preferred embodiment of this technical solution: the annular oil box is disposed inside the placement cylinder, and sealing components are equidistantly distributed and engaged on one side of the annular oil box; an oiling brush is provided on one side of the inside of the annular oil box; and a limit cap is engaged on one side of the annular oil box.

[0010] The limiting cover has equidistantly distributed threaded bolts on one side, one end of which passes through an oiling brush and is threadedly connected to an annular oil box. A polishing brush is provided on one side of the cover plate.

[0011] As a further preferred embodiment of this technical solution: a protective cover is fitted on one side of the polishing brush, and the protective cover engages with the cover plate.

[0012] As a further preferred embodiment of this technical solution: an observation window is installed on one side of the placement cylinder.

[0014] As a further preferred embodiment of this technical solution, a sealing ring is fixedly connected to one side of the limiting cover.

[0015] As a further preferred embodiment of this technical solution: the placement cylinder has equidistant grooves on one side, and a slider is slidably connected inside the groove, with one side of the slider being fixedly connected to the annular oil box.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This utility model uses a servo motor and a connecting seat to drive the motor rotor to rotate. During rotation, the rotor makes full contact with the oiling brush. Pulling the pull ring up and down moves the annular oil box and the oiling brush up and down, completing the comprehensive oiling treatment of the rotor. When necessary, the oiling brush can be removed and replaced with a grinding brush to grind and remove rust from the rotor surface. This effectively improves the overall practicality and applicability of the device.

[0018] 2. This utility model occupies little space, and the placement tube combined with the cover plate can effectively prevent oil from splashing out during the oiling process or debris from flying out during the grinding process, thus facilitating subsequent cleaning work.
