Description

Technical Field

[0001] The utility model relates to the field of magnetic ring processing, in particular to a high-efficiency fine grinding device for magnetic ring processing. Background Art

[0002] Magnetic ring is a ring-shaped component with a specific shape and magnetism. It is widely used in electronic equipment such as motors, sensors, transformers, and electromagnetic coils. The main purpose of magnetic ring processing is to process magnetic materials into magnetic ring products that meet design requirements through a series of process steps. Magnetic rings play a key role in electronic products. For example, the magnetic rings in motors are used to generate magnetic fields to drive motors, and the magnetic rings in sensors are used to detect changes in magnetic fields. Therefore, magnetic ring processing needs to meet the requirements of electronic products for precision, reliability, and stability. With the development of the automotive industry, magnetic rings are increasingly used in automotive parts. For example, in automotive generators, starters and other components, magnetic rings are one of the key components, and their processing quality directly affects the performance and reliability of the entire vehicle; magnetic rings are also used in medical equipment, aerospace, energy and other fields.

[0003] However, most traditional magnetic ring fine grinding devices use manually fixed magnetic rings and manual grinding. This method not only has low grinding efficiency and cannot meet the grinding needs of large quantities of magnetic ring burrs, but also has high labor costs. In addition, the manual grinding error rate is large and it is easy to cause grinding omission areas on the surface of the magnetic ring. At the same time, it also fails to achieve the effect of uniform force fine grinding of the burrs on the surface of the magnetic ring, which reduces the processing quality of the magnetic ring and increases the defective rate of the magnetic ring processing. Therefore, an efficient fine grinding device for magnetic ring processing is proposed. Utility Model Content

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] In this example, see Figure 1 and Figure 2 A technical solution: comprising a support base 1, a support column 2 and a top plate 3, four groups of support columns 2 are fixed around the top of the support base 1, and the top plate 3 is fixed on the top of the four groups of support columns 2;

[0030] Among them, the support base 1 is the existing fine grinding device base, and the support column 2 is the existing device support rod, which is used to provide a stable support function for the upper top plate 3. The number of support columns 2 can be increased according to actual conditions to ensure the stability of the top plate 3.

[0031] For further information, see Figure 1 and Figure 2 , a meshing disc 1 5 is provided inside the support base 1 at the output end of the driving motor 1 4, and meshing discs 2 6 are meshed on both sides of the meshing disc 1 5, and the meshing disc 2 6 is slidably connected to the support base 1, and an inner gear ring 7 is provided inside the support base 1, and the inner gear ring 7 is meshed with the meshing disc 2 6;

[0032] Among them, the driving motor 14 is an existing driving motor, which is used to provide a rotation function for the meshing disc 15 at its output end. The driving motor 14 is fixed inside the supporting base 1 by adopting an existing installation method, and is fixedly connected with the meshing disc 15 by adopting an existing connection technology. Both sides of the meshing disc 15 are meshedly connected with the meshing disc 26, so that when the driving motor 14 drives the meshing disc 15 to rotate, the rotation function can be transmitted to the meshing disc 26;

[0033] The meshing disc 2 6 is connected to the inner gear ring 7 inside the support base 1 by meshing, and the inner gear ring 7 is fixed to the inside of the support base 1 by fixing blocks on both sides. Therefore, when the meshing disc 1 5 rotates, the meshing disc 2 6 can slide in a circle inside the support base 1 by meshing with the meshing disc 1 5 and the inner gear ring 7 respectively. A clamping block is provided at the bottom of the meshing disc 2 6 to engage with the support base 1, thereby preventing the meshing disc 2 6 from detaching from the inside of the support base 1.

[0034] For further information, see Figure 1 and Figure 2 A support column 28 is fixed on the top of the engaging plate 26, and a clamping plate 19 is arranged on the top of the support column 28. At the same time, an adjusting button 10 is rotatably arranged on the inner side of the clamping plate 19, and a clamping plate 2 12 is threadedly connected to the outer side of the adjusting button 10. In addition, a limiting rod 11 is fixed on the top of the clamping plate 19, and a grinding sheet 13 is fixed on the inner side of the clamping plate 19 and the clamping plate 2 12, and the clamping plate 2 12 is slidably connected to the limiting rod 11;

[0035] The support column 28 is used to integrate the clamping plate 19 and the engaging plate 26, so that the engaging plate 26 can drive the clamping plate 19 and the parts above the clamping plate 19 to move synchronously through the support column 28 during the movement. The adjusting button 10 is connected to the clamping plate 19 by rotation, so that the clamping plate 19 can be rotated independently while providing a limit to the adjusting button 10.

[0036] The adjusting button 10 is threadedly connected to the second splint 12, and the second splint 12 is slidably connected to the limit rod 11, so that when the adjusting button 10 is rotated, the second splint 12 can be raised and lowered through the limit provided by the limit rod 11, and the lifting direction follows the rotation direction of the adjusting button 10. The grinding sheet 13 is an existing magnetic ring grinding sheet, which is fixed to the bottom of the second splint 12 and the inner side of the splint 1 9 by the existing installation method.

[0037] For further information, see Figure 1 and Figure 2 A second drive motor 14 is fixed on the top of the top plate 3, and a connecting shaft 15 is provided at the output end of the second drive motor 14. At the same time, two sets of second limit rods 16 are fixed on the bottom of the top plate 3. In addition, a connecting rod 17 is threadedly connected to the outer side of the connecting shaft 15, and the connecting rod 17 is slidably connected to the second limit rod 16, and a clamping shaft 18 is fixed to the bottom of the connecting rod 17;

At the same time, the connecting shaft 15 is fixedly installed with its output end by adopting the existing welding method. The connecting shaft 15 is internally threadedly connected with the connecting rod 17, and the connecting rod 17 is slidingly connected with the limiting rod 2 16. Therefore, when the connecting shaft 15 is rotated by the driving motor 2 14, the connecting rod 17 is lifted and lowered by the limiting function provided by the limiting rod 2 16, and the clamping shaft 18 is used to connect with the components of the supporting part below.

[0039] For further information, see Figure 1 and Figure 2 A support platform 20 is fixed at the top center of the support base 1, and a clamping block 21 is fixed at the top of the support platform 20. At the same time, a magnetic ring body 22 is arranged on the outer side of the clamping block 21 and fits with the support platform 20;

[0040] Among them, the support platform 20 is used to provide a support function for the magnetic ring body 22 above, and the clamping block 21 is used to provide a position limiting function for the magnetic ring body 22. At the same time, the inner sides of the support platform 20 and the clamping block 21 are provided with a groove structure for the clamping shaft 18 to be plugged in, so that when the clamping shaft 18 moves downward through the connecting rod 17, it can be plugged and engaged with the clamping block 21 to prevent the magnetic ring body 22 from falling off. The magnetic ring body 22 is an existing magnetic ring that needs to be polished.

[0041] For further information, see Figure 1 and Figure 2 The clamping assembly is composed of a mounting cylinder 191, a spring 192 and a pressure rod 193.

The pressure rod 193 is provided in the mounting cylinder 191 and passes through the outer side of the connecting rod 17. The pressure rod 193 is tightly pressed against the spring 192.

[0042] Among them, the mounting tube 191 is provided with four groups in a circular array based on the outer side of the connecting rod 17, and the pressure rod 193 forms an elastic telescopic structure inside the mounting tube 191 through the spring 192, so that when the non-magnetic protection pad at the bottom of the pressure rod 193 comes into contact with the magnetic ring body 22, the pressure rod 193 slides toward the inside of the mounting tube 191 through the downward pressure, so that the rebound force released by the spring 192 itself provides the downward pressure, tightening and clamping function to the magnetic ring body 22 through the pressure rod 193.

[0043] The implementation principle of this embodiment is: first, the support base 1 is stably placed in the specified position, the magnetic ring body 22 is placed above the support platform 20, and the through hole of the magnetic ring body 22 passes through the block 21, and then the driving motor 2 14 is turned on to drive the connecting shaft 15 to rotate, so that the connecting rod 17 moves downward, and the connecting rod 17 drives the pressure rod 193 inside the mounting tube 191 to synchronously descend, and then the pressure rod 193 provides a downward pressure function for the magnetic ring body 22, and then the adjusting knob 10 is turned to make the clamping plate 2 12 descend, and the clamping plate 2 12 and the grinding sheet 13 on the inner side of the clamping plate 1 9 clamp the magnetic ring body 22 to be polished, and then the driving motor 1 4 is turned on to drive the meshing plate 1 5 to rotate, so that the meshing plate 2 6 slides inside the support base 1, and then the meshing plate 2 6 drives the clamping plate 1 9 to rotate synchronously through the supporting column 2 8, so as to rotate and polish the magnetic ring body 22, and after the grinding of the magnetic ring body 22 is completed, the magnetic ring body 22 can be taken out according to the above operation.
