[0039] refer to Figures 1 to 3 An automated processing equipment for tubular NdFeB magnetic components is disclosed, used for grinding tubular magnetic components 610. The equipment includes a base 600, on which a discharge system 100, a transfer system 200, an outer wall grinding system 300, an inner wall grinding system 400, and an end-face chamfering system 500 are mounted. This design significantly improves production efficiency, reduces manpower requirements, and ensures processing accuracy and consistency.

[0040] Among them, reference Figure 4The discharge system 100 includes a material tray 110 and a pusher cylinder 130. The combination of the material tray 110 and the pusher cylinder 130 ensures the continuity and stability of the supply of magnetic components 610. The transfer system 200 includes a sliding seat plate 210, which is mounted on the base 600 via a first sliding module 220. A fixing component is mounted on the sliding seat plate 210. A discharge port 211 is provided on the sliding seat plate 210, and a discharge ramp 601 is provided on the base 600. The transfer system 200 uses the sliding seat plate 210 and the first sliding module 220 to sequentially feed the magnetic components 610 through the outer wall grinding system 300, the inner wall grinding system 400, and the end face chamfering system 500. The pusher cylinder 130 pushes the magnetic components 610 from the material tray 110 into the transfer system 200, and the fixing component clamps and fixes the magnetic components 610. The outer wall polishing system 300 includes a clamping assembly and an outer wall polishing assembly, which are located on both sides of the transfer system 200 and arranged opposite to each other. The clamping assembly and the outer wall polishing assembly cooperate to polish the outer wall of the magnetic component 610. The inner wall polishing system 400 is located on one side of the transfer system 200. The end face chamfering system 500 includes two sets of chamfering assemblies, which are located on both sides of the transfer system 200 and arranged opposite to each other. The opposing arrangement of the two sets of chamfering assemblies allows both ends of the magnetic component 610 to be chamfered simultaneously, which helps to improve processing efficiency.

[0041] The external wall polishing system 300 described in this application is as follows: (See reference) Figures 7 to 10 The clamping assembly includes a clamping mounting base 310, on which a plurality of annularly distributed clamping blocks 311 are mounted. A reset mechanism for resetting the clamping blocks 311 is provided within the clamping mounting base 310. The outer wall grinding assembly includes an outer wall grinding seat 320, on which a plurality of annularly distributed outer wall grinding blocks 321 are mounted. A reset mechanism for pressing the outer wall grinding blocks 321 against the outer wall of the magnetic component 610 is provided within the outer wall grinding seat 320. The inward surfaces of the plurality of clamping blocks 311 cooperate to form a frustum-shaped expansion cavity. An expansion block 326 that cooperates with the expansion cavity is rotatably mounted on the outer wall grinding seat 320. The outward surfaces of several clamping blocks 311 abut against the inner wall of the magnetic component 610 to clamp the magnetic component 610, while the inward surfaces of several outer wall grinding blocks 321 serve as grinding surfaces to grind the outer wall of the magnetic component 610. The clamping mounting base 310 is provided with a rotating slide groove 313, and the ends of the outer wall grinding blocks 321 are provided with ball bearings 327. The design of the ball bearings 327 reduces friction, making the entire grinding process smoother, reducing energy consumption, and extending the service life of the equipment.

[0042] The working principle of the outer wall polishing system 300 is as follows: The clamping assembly moves forward, causing the clamping blocks 311 to extend into the magnetic component 610. Under the action of the reset mechanism, the diameter of the column formed by the cooperation of several clamping blocks 311 is smaller than the inner diameter of the magnetic component 610. At this time, the magnetic component 610 is already hung on the clamping assembly, and the first clamping plate 230 and the second clamping plate 231 release their clamping of the magnetic component 610. Then, the outer wall polishing assembly moves forward, and the expansion block 326 of the outer wall polishing assembly is inserted into the expansion cavity. The diameter of the column formed by the cooperation of the clamping blocks 311 increases, and at the same time, the inner surface of the outer wall polishing block 321 contacts the outer wall of the magnetic component 610 until the outer surface of the clamping block 311 abuts against the inner wall of the magnetic component 610. The ball bearings 327 on the outer wall polishing block 321 enter the rotating groove 313, thereby achieving the clamping of the magnetic component 610. Then, the drive motor 322 drives the outer wall grinding seat 320 to rotate, and the inner surface of the outer wall grinding block 321 grinds the outer wall of the magnetic component 610. After grinding, the outer wall grinding assembly retracts, and the first clamping plate 230 and the second clamping plate 231 cooperate to fix the magnetic component 610, and then the clamping assembly retracts. After the outer wall grinding system 300 returns to its original position, the transfer system 200 sends the magnetic component 610 to the inner wall grinding system 400 for inner wall grinding processing.

[0043] The internal wall polishing system 400 described in this application is as follows: (See reference) Figure 11 The inner wall polishing system 400 includes an inner wall polishing seat 410, on which a plurality of annularly distributed inner wall polishing blocks 411 are mounted. The inner wall polishing seat 410 is provided with a reset mechanism for pressing the inner wall polishing blocks 411 against the inner wall of the magnetic component 610.

[0044] The end face chamfering system 500 described in this application is as follows: (See reference) Figure 12 The chamfering assembly includes a chamfering mounting base 510, on which a chamfering tool holder 511 is mounted. The chamfering tool holder 511 has a chamfering groove 512, and chamfering edges 513 are provided on both the inner and outer sides of the chamfering groove 512. During chamfering, the first clamping plate 230 and the second clamping plate 231 cooperate to fix the magnetic component 610. The two sets of chamfering assemblies move forward, causing the end face of the magnetic component 610 to enter the chamfering groove 512. The drive motor 322 drives the chamfering tool holder 511 to rotate, and the chamfering edges 513 chamfer the edge of the end face of the magnetic component 610.

[0045] For ease of design and manufacturing, the feed systems of the outer wall grinding assembly, the inner wall grinding system 400, and the chamfering assembly are designed identically, referencing... Figure 7Each component includes a feed base plate 340, a feed cylinder 342, a drive motor 322, and a transmission box 323. The feed base plate 340 is assembled to the base 600 via a feed sliding module 341, and the feed cylinder 342 is connected to the feed base plate 340. The drive motor 322 and the transmission box 323 are connected via a belt drive module 324, and the transmission box 323 is equipped with a fixing chuck 325 for fixing various machining tools. (Reference) Figure 9 The clamping assembly includes a feed plate 340, a feed cylinder 342, and a fixed base 312. The feed plate 340 is assembled to the base 600 via a feed sliding module 341, and the feed cylinder 342 is connected to the feed plate 340. A fixed clamping plate 325 is mounted on the fixed base 312.

[0046] The reset mechanisms in the clamping assembly, outer wall grinding assembly, and chamfering assembly are designed identically, as shown in the reference. Figure 8 and Figure 10 Both the clamping and grinding components include a reset slide column 330. The clamping mounting base 310 or the outer wall grinding base 320 has a sliding cavity 335 for accommodating the reset slide column 330. The reset slide column 330 is provided with a retaining ring 331 and a reset spring 332. The sliding cavity 335 includes a reset cavity for accommodating the retaining ring 331 and the reset spring 332. The reset slide column 330 is provided with a limiting post 333, and the clamping mounting base 310 or the outer wall grinding base 320 is provided with a limiting groove 334 for sliding the limiting post 333. The difference is that the reset force of the reset mechanism in the clamping assembly and the outer wall grinding assembly is radially directed towards the center, allowing the clamping block 311 to reset when the clamping of the magnetic component 610 is released, and allowing the outer wall grinding block 321 to adhere tightly to the outer wall of the magnetic component 610 to ensure grinding quality. The reset force of the reset mechanism in the chamfering assembly acts radially away from the center, so that the inner wall grinding block 411 can fit tightly against the inner wall of the magnetic part 610 to ensure the grinding quality.

[0047] In this application, references Figure 4 The discharge system 100 also includes a sorting seat 120. The material tray 110 is connected to a discharge track 111, and the sorting seat 120 is mounted at the end of the discharge track 111. A through groove is provided in the sorting seat 120, through which the magnetic component 610 to be ground enters the through groove of the sorting seat 120 via the discharge track 111. The pusher cylinder 130 is connected to a pusher rod 131 adapted to the through groove. The through groove design in the sorting seat 120, combined with the pusher rod 131, further guides and sorts the magnetic component 610, allowing it to enter the subsequent processing stage in a specific posture. This ensures the continuity and efficiency of the processing, and improves the automation level of the overall discharge system 100.

[0048] To further improve the automation level of material discharge, the discharge system 100 also includes a hopper 140, the bottom of which is provided with a discharge ramp 141, the end of which is located above the material tray 110. The hopper 140 is mounted on a material rack 150, which is equipped with a baffle cylinder 160. The baffle cylinder 160 is connected to a baffle plate 161, which extends into the baffle 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.

[0049] In the 200 transfer systems, see reference. Figure 5 and Figure 6 The fixing assembly includes a first clamping plate 230 and a second clamping plate 231. Both the first clamping plate 230 and the second clamping plate 231 are provided with clamping half-grooves 232, which cooperate to form a clamping groove for placing the magnetic component 610. The first clamping plate 230 is assembled and fixed to the sliding base plate 210, and the second clamping plate 231 is assembled and fixed to the sliding base plate 210 via a second sliding module 240.

[0050] During the transfer process, the clamping half-grooves 232 on the first clamping plate 230 and the second clamping plate 231 cooperate to form a complete clamping groove, clamping and fixing the magnetic component 610 pushed from the through groove. The sliding base plate 210 moves smoothly on the base 600 through the first sliding module 220, transferring the magnetic component 610 sequentially through the outer wall grinding system 300, the inner wall grinding system 400, and the end face chamfering system 500 for processing. After all processing operations are completed, the second sliding module 240 drives the second clamping plate 231 to move backward, and the magnetic component 610 is automatically released and falls into the discharge port 211, then smoothly slides down the discharge ramp 601 set on the base 600, completing the entire processing flow. This design significantly improves production continuity and operational efficiency, while reducing the labor intensity of operators and potentially reducing product damage caused by human error, thereby optimizing resource utilization and production costs while ensuring product quality.

[0051] Furthermore, a material drop seat 250 is also provided on the sliding seat plate 210. The first clamping plate 230 is installed on the material drop seat 250. An auxiliary slide 251 is provided below the clamping half groove 232 corresponding to the first clamping plate 230 on the material drop seat 250. The material drop port 211 is located at the end of the auxiliary slide 251. The setting of the auxiliary slide 251 ensures that the magnetic component 610 can slide smoothly along the preset path of the auxiliary slide 251 after release. This design effectively prevents the magnetic component 610 from falling out of place and avoids the problem of the magnetic component 610 falling outside the material drop port 211. At the same time, it also significantly reduces the impact force of the magnetic component 610 falling and prevents the potential damage caused by direct impact with the sliding seat plate 210.

[0052] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
