Description

Technical Field

[0001] The invention relates to the technical field of stator and rotor polishing, in particular to a surface polishing system for producing motor stators and rotors. Background Art

[0002] A surface polishing system for the production of motor stators and rotors usually consists of multiple components, including a base, a polishing device, a bracket, a transmission device and a control system. The base provides stability for the system, while the polishing device is responsible for grinding and polishing the surface of the stator and rotor. The transmission device transmits power to the polishing device to ensure that it acts evenly on the surface of the stator and rotor, thereby achieving the purpose of removing surface roughness. The control system is used to adjust polishing parameters, such as speed, pressure, etc., to achieve polishing effects with different precision requirements. During operation, the stator and rotor are fixed on the bracket, and the transmission device drives the polishing device to perform uniform surface treatment on the stator and rotor, ultimately achieving a smooth surface with no obvious wear marks.

[0003] Although the system can achieve surface polishing of the motor stator and rotor, its design still has some defects. The transmission device and polishing device in the system are limited by the mechanical structure, and the wear during the polishing process is difficult to control, which increases the risk of uneven polishing and affects the polishing quality. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a surface polishing system for the production of motor stators and rotors, which solves the problem that the wear during the polishing process is difficult to control, leading to an increased risk of uneven polishing.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A surface polishing system for motor stator and rotor production, comprising: A lower bracket, on which a plurality of vertical brackets for support are fixed, the upper ends of the vertical brackets are fixedly connected to a panel, and the panel is provided with a rotating opening; A power device, comprising a support assembly and a power assembly, wherein the power assembly comprises a motor for providing power, a plurality of elastic rods fixed to the output end of the motor, and a rubber ball fixed to the elastic rod; Two supporting devices are provided on both sides of the panel, respectively, and the supporting devices include a second lower support plate, a first electric push rod, a connection block and a connecting rod; The polishing device is arranged on the connecting rod. The polishing device comprises an opening and closing component, a polishing box and two sets of clamping devices for clamping. A swing gap is formed between the polishing box and the panel.

[0006] Preferably, the support assembly comprises a first lower support plate fixedly connected to the lower support, and a side support fixedly connected to the first lower support plate, and a side surface of the side support is fixedly connected to the motor.

[0007] Preferably: the second lower support plate is fixedly connected to the side surface of the panel, the upper side of the second lower support plate is fixedly connected to the first electric push rod, the output end of the first electric push rod is fixedly connected to the connecting block, and the connecting block is rotatably connected to the connecting rod.

[0008] Preferably, the opening and closing assembly comprises a box door, a handle and a lock hole, the box door is rotatably connected to the polishing device, and the handle and the lock hole are both located on the box door.

[0009] Preferably: the clamping device includes a fixing component and a clamping component, the fixing component includes a first permanent magnet slidably connected to the polishing box, a second permanent magnet magnetically connected to the first permanent magnet, a second electromagnet fixed in the first permanent magnet, and a first electromagnet fixed in the second permanent magnet.

[0010] Preferably, the clamping assembly comprises a second electric push rod, a fixing rod, a clamping sheet and a support frame, the output end of the second electric push rod is fixedly connected to the second permanent magnet, and the fixing rod is provided with a mounting groove.

[0011] Preferably: the mounting groove is fixedly connected to the second electric push rod, the lower side of the fixing rod is fixedly connected to the clamping plate, the side surface of the clamping plate is fixedly connected to the third electromagnet, and the first electromagnet, the second electromagnet and the second electric push rod are all electrically connected to an external power supply.

[0012] Preferably, a polishing cavity is formed inside the polishing box, and the cross section of the polishing box is elliptical to increase the polishing effect, and a gap is formed between the first permanent magnet and the second permanent magnet.

[0013] Preferably, a support frame is fixed to the lower side of the lower bracket, and a roller is rotatably connected inside the support frame.

[0014] Preferably, a threaded rod is threadedly connected to the lower side of the lower bracket, and a supporting foot is fixedly connected to the lower side of the threaded rod.

[0015] The present invention provides a surface polishing system for the production of motor stators and rotors. It has the following beneficial effects: The surface polishing system for the motor stator and rotor production uses an elliptical cross-section design for the polishing box. This innovation not only increases the effective contact area for polishing, but also optimizes the flow characteristics between the abrasive and the workpiece surface through fluid mechanics, improving the uniformity of abrasive distribution during the polishing process. This design can effectively reduce the deposition and aggregation of abrasives during the polishing process, thereby ensuring the uniformity and stability of the polishing effect.

[0016] The design of the clamping device ensures that the clamping position is located on the upper side of the stator and rotor, fully avoiding the impact on the polishing process on the lower side. During the polishing process, the power device can generate periodic vibrations. When the third electromagnet is energized, this vibration causes friction between the stator and rotor and the polishing sand, enhancing the polishing effect. When the electromagnet is not energized, the vibration enables the stator and rotor to rotate within a certain range, further promoting the uniform distribution of the polishing sand and improving the polishing effect.

[0017] The length of the first electric push rod changes, and the oval polishing box is used to change the swing of the polishing box to adapt to stators and rotors of different shapes and sizes. This flexibility enables the system to be widely used in the polishing needs of various workpieces. At the same time, when the second electric push rod is shortened, the knocking effect of the rubber ball can effectively separate the polishing sand from the stator and rotor, preventing the accumulation of polishing sand and loss during the recovery process.
