Description

Technical Field

[0001] The present invention relates to the technical field of stator and rotor polishing, and specifically to a surface polishing system for the production of 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, etc. The base provides the stability of the system, and the polishing device is responsible for grinding and polishing the surfaces of the stators and rotors. The transmission device transmits power to the polishing device to ensure its uniform action on the surfaces of the stators and rotors, 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 the operation, the stators and rotors are fixed on the bracket, and the transmission device drives the polishing device to perform uniform surface treatment on the stators and rotors, finally achieving the effect of smooth surface and no obvious abrasion marks.

[0003] Although this system can achieve the surface polishing of motor stators and rotors, its design still has some defects. The transmission device and the polishing device in the system are limited by the mechanical structure, and the wear situation during the polishing process is difficult to control, resulting in an increased risk of uneven polishing and affecting the polishing quality. Summary of the Invention

[0006] A lower bracket, on which several vertical brackets for support are fixed. The upper ends of the vertical brackets are fixedly connected to a panel, and a rotation opening is provided on the panel;

[0007] A power device, which includes a support assembly and a power assembly. The power assembly includes a motor for providing power, several elastic rods fixed to the output end of the motor, and rubber balls fixed to the elastic rods;

[0008] Support devices, the number of which is two and are respectively located on both sides of the panel. The support devices include second lower support plates, first electric push rods, connecting blocks, and connecting rods;

[0009] A polishing device, which is arranged on the connecting rod. The polishing device includes an opening and closing assembly, a polishing box, and two sets of clamping devices for clamping. A swinging gap is formed between the polishing box and the panel.

[0010] Preferably, the support assembly includes a first lower support plate fixedly connected to the lower bracket and a side bracket fixedly connected to the first lower support plate, and the side surface of the side bracket is fixedly connected to the motor.

[0011] 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.

[0012] Preferably, the opening and closing assembly includes a box door, a handle and a keyhole. The box door is rotatably connected to the polishing device, and the handle and the keyhole are both located on the box door.

[0013] Preferably, the clamping device includes a fixing assembly and a clamping assembly. The fixing assembly 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.

[0014] Preferably, the clamping assembly includes a second electric push rod, a fixing rod, a clamping piece and a third electromagnet. The output end of the second electric push rod is fixedly connected to the second permanent magnet, and an installation groove is provided on the fixing rod.

[0015] Preferably, the installation groove is fixedly connected to the second electric push rod, the lower side of the fixing rod is fixedly connected to the clamping piece, the side surface of the clamping piece 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 source.

[0016] Preferably, a polishing cavity is formed inside the polishing box. The cross section of the polishing box is oval to enhance the polishing effect, and a gap is formed between the first permanent magnet and the second permanent magnet.

[0017] Preferably, a support frame is fixed to the lower side of the lower bracket, and a roller is rotatably connected inside the support frame.

[0018] Preferably, a threaded rod is threadedly connected to the lower side of the lower bracket, and a support foot is fixedly connected to the lower side of the threaded rod.

[0019] The present invention provides a surface polishing system for the production of motor stators and rotors. It has the following beneficial effects:

[0020] The surface polishing system for the production of the stator and rotor of the motor has a polishing box designed with an elliptical cross-section. This innovation not only increases the effective contact area of polishing but also optimizes the flow characteristics between the abrasive and the workpiece surface through fluid mechanics, improving the uniformity of the distribution of the abrasive during the polishing process. This design can effectively reduce the deposition and aggregation of the abrasive during the polishing process, thus ensuring the uniformity and stability of the polishing effect.

[0021] The design of the clamping device ensures that the clamping position is on the upper side of the stator and rotor, fully avoiding the influence on the polishing process of 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.

[0022] The change in the length of the first electric push rod, combined with the elliptical polishing box, can change the swing amplitude of the polishing box to adapt to stators and rotors of different shapes and sizes. This flexibility enables the system to be widely applied to the polishing requirements of various workpieces. At the same time, when the second electric push rod shortens, combined with the knocking action of the rubber ball, it can effectively separate the polishing sand from the stator and rotor, preventing the accumulation of polishing sand and losses during the recycling process.

[0043] Working principle: The operator selects the motor stator and rotor workpieces to be polished, prepares them, starts the clamping device 22, controls the clamping piece 30 to clamp the workpiece through the second electric push rod 29, ensuring that the workpiece is stable and will not move during the polishing process.

The polishing device 16 is connected to the support device 11 through the connecting rod 15 and starts to work. The polishing cavity 21 formed inside the polishing box 17 starts to operate, and uniform polishing is carried out by using the contact between the rubber ball 10 and the workpiece. The swing gap between the polishing box 17 and the panel 3 allows the polishing device 16 to swing slightly during operation, thereby enhancing the polishing effect and improving the uniformity of surface treatment. The first electric push rod 13 in the support device 11 can adjust the height of the polishing device 16 as needed to adapt to workpieces of different sizes and shapes, ensuring the best polishing effect. The operator monitors the running state of the system in real time during the polishing process to ensure the stable operation of the motor and the firmness of the clamping device 22, and makes adjustments if necessary. When the polishing time reaches the preset standard, the work of the motor 8 and the clamping device 22 is stopped, the pressure on the workpiece by the clamping is released, and the polished workpiece is taken out. After completing the polishing task, the operator cleans the system to ensure that there are no residues affecting the next use.
