Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polishing equipment, in particular to a magnetic core polishing equipment. Background Art
[0002] Core polishing is a key process step, which is essential to ensure the surface finish and performance of the core. During the core manufacturing process, due to material processing, heat treatment or other reasons, tiny defects such as unevenness, burrs or oxides may appear on the core surface. These defects not only affect the appearance of the core, but may also have an adverse effect on the magnetic properties, such as reducing the magnetic permeability and increasing eddy current loss. Therefore, core polishing is a key link in improving the quality of the core. The core polishing process usually adopts mechanical polishing or chemical polishing. Mechanical polishing mainly uses the friction of polishing tools (such as polishing wheels, polishing cloths, etc.) and polishing agents (such as abrasive pastes, polishing liquids, etc.) to remove the unevenness and burrs on the surface of the core. Chemical polishing uses the principle of chemical reaction to achieve the purpose of removing oxides and impurities by reacting the chemicals in the polishing liquid with the surface of the core. In the core polishing process, it is crucial to choose the right polishing method and polishing agent. Different core materials and surface conditions require different polishing strategies. For example, for hard core materials, harder polishing tools or coarser abrasive pastes may be required, while for soft core materials, softer polishing cloths or finer polishing fluids may be required. In addition, during the polishing process, attention should be paid to factors such as the control of polishing force, the control of polishing time, and the cleanliness of the polishing environment. Excessive polishing force or long polishing time may cause excessive wear on the core surface, while pollution in the polishing environment may introduce new impurities and affect the polishing effect. In summary, core polishing is a process that requires professional skills and experience. It requires operators to be familiar with the characteristics of core materials and polishing principles, and to be able to select appropriate polishing methods and parameters according to specific circumstances to ensure that the surface finish and performance of the core meet the requirements.
[0003] In the prior art, in order to achieve the polishing effect, workers directly throw the magnetic core into the inside of the polishing machine, and the magnetic core is polished at different parts under the action of the cloth wheel inside the polishing machine; however, in this way, the magnetic core cannot be stably polished during the polishing process, that is, the magnetic core keeps jumping inside the machine during the polishing process, which easily leads to uneven polishing degree of different polishing surfaces, thereby affecting the polishing quality.

[0012] According to a further technical solution, a handle is installed on one side of the friction cylinder.
[0013] Compared with the prior art, the utility model provides a magnetic core polishing device, which has the following beneficial effects:
[0014] By setting up the linear polishing assembly and the end face polishing assembly, the magnetic core is fixed and rotated in a straight line during the polishing process. The side and cross-section polishing components achieve a stable polishing effect, avoiding the problem of uneven polishing caused by the continuous jumping of the magnetic core in the polishing machine. When in use, the bearing is embedded and installed inside the bearing seat, and then the rotating shaft is docked and installed inside the bearing to ensure the linear rotation of the rotating shaft; then the motor is installed on one side of the rotating shaft using a bracket to achieve the driving effect. A shaft shoulder is provided on the rotating shaft. When polishing is required, the magnetic core is placed on the shaft shoulder, and then the end cover is tightened and installed on the side of the magnetic core using a threaded structure to achieve the fixation of the magnetic core. At this time, the polishing plate is against the side of the magnetic core, and the magnetic core is driven to rotate by the motor. The side of the magnetic core is continuously rotated and polished on the inner wall of the polishing plate. This polishing method ensures the stability of the magnetic core and avoids the problem of uneven polishing. In addition, in order to achieve multi-directional polishing, we can also control the friction cylinder to contact the side of the magnetic core through the handle, thereby achieving the polishing effect of the magnetic core plane, and the polishing process will not cause the problem of unstable jumping of the magnetic core.

The motor 4 is docked and installed on one side of the rotating shaft 5. A shoulder 9 is provided on one side of the rotating shaft 5.

[0026] A magnetic core polishing device, further comprising:
[0027] The end surface polishing assembly 3 includes a fixed rod 16 installed on one side of the workbench 1, a slider 17 is provided on one side of the fixed rod 16, and a slide groove 18 moves back and forth on the surface of the slider 17, thereby driving the friction cylinder 19 to polish the side of the magnetic core 10.

[0028] A magnetic core polishing device, a handle 20 is installed on one side of a friction cylinder 19 for manually controlling the reciprocating movement of the friction cylinder 19.
[0029] In the actual operation of this device, in order to avoid the following problems existing in the polishing assembly of the prior art: In the prior art, in order to achieve the polishing effect, the worker directly throws the magnetic core into the interior of the polishing machine, and the magnetic core is polished at different parts under the action of the cloth wheel inside the polishing machine; however, in this way, the magnetic core cannot be polished stably during the polishing process, that is, the magnetic core constantly jumps inside the machine during the polishing process, which easily leads to uneven polishing of different polishing surfaces, thereby affecting the polishing quality. The utility model sets a linear polishing assembly 2 and an end face polishing assembly 3, so that the magnetic core 10 is fixed and rotated in a straight line during the polishing process, and a stable polishing effect is achieved through the polishing components of the side and cross section, avoiding the problem of uneven polishing caused by the continuous jumping of the magnetic core 10 in the polishing machine.
