[0040] refer to Figures 1 to 9 A tubular NdFeB magnetic component 410 grinding device is used for grinding the tubular magnetic component 410, comprising a base 400, on which a discharging mechanism 100, a transfer mechanism 200 and a grinding mechanism 300 are assembled.

[0041] The specific structure of the discharging mechanism 100 of the present application is as follows: it includes a material tray 110, a sorting seat 120 and a pushing cylinder 130. The material tray 110 is connected to a discharging chute 111, and the sorting seat 120 is assembled at the end of the discharging chute 111. A through slot is provided in the sorting seat 120, and the magnetic piece 410 to be polished enters the through slot of the sorting seat 120 via the discharging chute 111. The pushing cylinder 130 is connected to a pushing rod 131 adapted to the through slot. The combination of the material tray 110 and the discharging chute 111 ensures the smooth transfer of the magnetic piece 410, and the through slot design in the sorting seat 120 cooperates with the pushing rod 131 to further guide and sort the magnetic piece 410, so that it can enter the subsequent processing link in a specific posture, ensuring the continuity and efficiency of the processing process, and improving the automation level of the overall discharging system.

[0042] In order to further improve the degree of automation of discharging, the discharging mechanism 100 further includes a hopper 140, and a discharge ramp 141 is provided at the bottom of the hopper 140, and the end of the discharge ramp 141 is located above the material tray 110. The hopper 140 is mounted on a material rack 150, and a material blocking cylinder 160 is mounted on the material rack 150. The material blocking cylinder 160 is connected to a material blocking plate 161, and the material blocking plate 161 extends into the material blocking ramp. This design significantly increases the capacity of each feeding, greatly reduces the frequency of manual intervention, thereby reducing labor intensity and improving production efficiency.

[0043] The specific structure of the transfer mechanism 200 of the present application is as follows: it includes a sliding seat plate 210, and the sliding seat plate 210 is assembled on the base 400 through a first sliding module 220, and a fixing component is assembled on the sliding seat plate 210. The fixing component includes a first clamping plate 230 and a second clamping plate 231, and the first clamping plate 230 and the second clamping plate 231 are both provided with a clamping half groove 232, and the clamping half grooves 232 on the two clamping plates cooperate to form a clamping groove for placing the magnetic part 410. The first clamping plate 230 is assembled and fixed to the sliding seat plate 210, and the second clamping plate 231 is assembled and fixed to the sliding seat plate 210 through a second sliding module 240. A blanking port 211 is provided on the sliding seat plate 210, and a blanking ramp 401 is provided on the base 400.

[0044] During the transportation process, the first clamping plate 230 and the clamping half groove 232 on the second clamping plate 231 cooperate with each other to form a complete clamping groove, and the magnetic piece 410 pushed from the through groove is clamped and fixed. The sliding seat plate 210 moves smoothly on the base 400 through the first sliding module 220, and the magnetic piece 410 is transferred to the grinding mechanism 300 for grinding. After the grinding operation is completed, the second sliding module 240 drives the second clamping plate 231 to move backward, and the magnetic piece 410 is automatically released and falls into the blanking port 211, and then smoothly slides down along the blanking ramp 401 set on the base 400 to complete the entire processing process. Such a design significantly improves production continuity and operating efficiency, while reducing the labor intensity of operators, and may reduce product damage caused by human operating errors, thereby ensuring product quality while optimizing resource utilization and production costs.

[0045] Furthermore, a blanking seat 250 is also provided on the sliding seat plate 210, the first clamping plate 230 is mounted on the blanking seat 250, the blanking seat 250 is provided with an auxiliary slide 251 below the clamping half groove 232 corresponding to the first clamping plate 230, and the blanking port 211 is located at the end of the auxiliary slide 251. Specifically, the setting of the auxiliary slide 251 ensures that the magnetic part 410 can slide smoothly along the preset path of the auxiliary slide 251 after being released. Such a design effectively prevents the magnetic part 410 from falling out of position and avoids the problem of the magnetic part 410 falling outside the blanking port 211. At the same time, it also significantly reduces the impact force of the magnetic part 410 falling, preventing the possible damage caused by direct impact on the sliding seat plate 210.

[0046] The grinding mechanism 300 described in the present application includes a clamping assembly and a grinding assembly that are relatively arranged. The clamping assembly and the grinding assembly cooperate to grind the outer wall of the magnetic component 410. The clamping assembly includes a clamping mounting seat 310, on which a plurality of annularly distributed clamping blocks 311 are mounted, and a reset structure for resetting the clamping blocks 311 is arranged in the clamping mounting seat 310. The grinding assembly includes a grinding mounting seat 320, on which a plurality of annularly distributed grinding blocks 321 are mounted, and a reset structure for making the grinding blocks 321 rest against the outer wall of the magnetic component 410 is arranged in the grinding mounting seat 320.

[0047] The reset structures of the clamping assembly and the grinding assembly are the same, both of which include a reset sliding column 330. A sliding cavity 335 for accommodating the reset sliding column 330 is provided in the clamping mounting seat 310 or the grinding mounting seat 320. A retaining ring 331 and a reset spring 332 are provided on the reset sliding column 330. The sliding cavity 335 includes a reset cavity for accommodating the retaining ring 331 and the reset spring 332. A limiting column 333 is provided on the reset sliding column 330, and a limiting sliding groove 334 for the limiting column 333 to slide is provided on the clamping mounting seat 310 or the grinding mounting seat 320.

[0048] In addition, the clamping assembly and the grinding assembly both include a feed base plate 340 and a feed cylinder 342. The feed base plate 340 is assembled with the base 400 through a feed sliding module 341, and the feed cylinder 342 is connected to the feed base plate 340. The clamping assembly also includes a fixed seat 312, on which a clamping chuck 313 is assembled, and the clamping mounting seat 310 is assembled on the clamping chuck 313. The grinding assembly also includes a grinding motor 322 and a transmission box 323. The grinding motor 322 and the transmission box 323 are connected through a belt transmission module 324, and a grinding chuck 325 is assembled on the transmission box 323, and the grinding mounting seat 320 is assembled on the grinding chuck 325.

[0049] The grinding scheme of the present application is designed as follows: the inward surfaces of the clamping blocks 311 cooperate to form a truncated cone-shaped expansion cavity, and the expansion block 326 that cooperates with the expansion cavity is rotatably mounted on the grinding mount 320. The outward surfaces of the clamping blocks 311 cooperate to abut against the inner wall of the magnetic part 410 to clamp the magnetic part 410, and the inward surfaces of the grinding blocks 321 serve as grinding surfaces to grind the outer wall of the magnetic part 410. The clamping mount 310 is provided with a rotating slide 314, and the end of the grinding block 321 is provided with a rolling member 327.

[0050] The working principle of the grinding mechanism 300 is as follows: the clamping assembly moves forward, so that the clamping block 311 extends into the magnetic part 410. At this time, under the action of the reset structure, the diameter of the column formed by the plurality of clamping blocks 311 is smaller than the inner diameter of the magnetic part 410. At this time, the magnetic part 410 has been hung on the clamping assembly, and the first clamping plate 230 and the second clamping plate 231 release the clamping of the magnetic part 410. Then the grinding assembly moves forward, and the expansion block 326 of the grinding assembly is inserted into the expansion cavity. The diameter of the column formed by the clamping block 311 becomes larger, and at the same time, the inward surface of the grinding block 321 contacts the outer wall of the magnetic part 410 until the outward surface of the clamping block 311 abuts against the inner wall of the magnetic part 410, and the rolling member 327 on the grinding block 321 enters the rotating slide 314, thereby achieving the clamping of the magnetic part 410. Then the grinding motor 322 drives the grinding mount 320 to rotate, and the inward surface of the grinding block 321 grinds the outer wall of the magnetic part 410. After the grinding is completed, the grinding assembly retreats, the first clamping plate 230 and the second clamping plate 231 cooperate to fix the magnetic part 410, and then the clamping assembly retreats. After the grinding mechanism 300 returns to its original position, the second clamping plate 231 retreats, releases the clamping of the magnetic part 410, and the magnetic part 410 falls into the blanking port 211.

[0051] The grinding mechanism 300 of the present application not only realizes high-precision grinding of the magnetic outer wall parts, but also can automatically clamp and drop materials to improve processing efficiency, reduce manpower dependence, and ensure the stability and consistency of the grinding production process of the magnetic parts 410.

[0052] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
