The front conveyor belt 31 is rotatably connected to the threaded rod 41. The threaded rod 41 is screwed to the front clamping block 42 via a threaded structure. Two slots 410 are defined at the front end of the threaded rod 41. A plurality of spur tooth grooves 420 corresponding to the mid-range spur gear 33 are defined around the outer surface of the front clamping block 42. The rear conveyor belt 31 is rotatably connected to a spline shaft 43; a rear clamping block 44 aligned with the front clamping block 42 is slidably connected to the spline shaft 43; a compression spring 45 is fixedly connected between the rear clamping block 44 and the spline shaft 43, and the compression spring 45 is sleeved on the outer surface of the spline shaft 43; each front clamping block 42 is fixedly connected to a non-slip washer 46 on the side facing the corresponding rear clamping block 44; each rear clamping block 44 is also fixedly connected to a non-slip washer 46 on the side facing the corresponding front clamping block 42;

[0029] like Figure 3 and Figure 6As shown, the loading assembly includes a lower electric slider 51, a lower positioning block 52, an upper electric slider 53, an upper positioning block 54, a loading drive motor 55, a loading spur gear 56 and a loading electric telescopic block 57; the lower side of the loading rack 5 is slidingly connected with two lower electric sliders 51 that are symmetrical to each other front and back; each of the two lower electric sliders 51 is fixed with a lower positioning block 52; the discharging slide 21 is aligned with the two lower positioning blocks 52; the upper side of the loading rack 5 is slidingly connected with two upper electric sliders 53 that are symmetrical to each other front and back; each of the two upper electric sliders 53 is fixed with an upper positioning block 54; the loading drive motor 55 is installed on the loading rack 5; the output shaft of the loading drive motor 55 is fixed with a loading spur gear 56 corresponding to the straight tooth groove 420 of the front clamp 42; the loading electric telescopic block 57 corresponding to the slot 410 of the threaded rod 41 is installed on the loading rack 5.

[0030] like Figure 3 and Figure 9 As shown, the blanking assembly includes a blanking drive motor 71, a blanking spur gear 72 and a blanking electric telescopic clamp 73; the blanking drive motor 71 is installed on the blanking frame 7; the output shaft of the blanking drive motor 71 is fixedly connected to the blanking spur gear 72 corresponding to the straight tooth groove 420 of the front clamping block 42; the blanking electric telescopic clamp 73 corresponding to the slot 410 of the threaded rod 41 is installed on the blanking frame 7.

[0031] First, the loading working step of the automatic grinding device for producing magnetic products of the present invention is carried out. The electric conveyor 3 drives the conveyor belt 31 to sequentially convey and align each clamping rotating assembly to the loading rack 5. When the straight tooth groove 420 of the front clamping block 42 in the clamping rotating assembly is aligned with the loading spur gear 56, the electric discharging machine 2 first lowers the magnetic column blank along the discharging slide 21 and places it between the two lower positioning blocks 52. Then, the two lower electric sliders 51 drive the two lower positioning blocks 52 to move toward each other. At the same time, the two upper electric sliders 53 drive the two upper positioning blocks 54 to move toward each other. When the magnetic column blank is completely clamped between the two lower positioning blocks 52 and the two lower positioning blocks 52, the axis of the magnetic column blank can be aligned with the axis of the front clamping block 42 and the rear clamping block 44 in the clamping rotation assembly. Then the loading electric telescopic clamping block 57 extends outward to the slot 410 inserted into the threaded rod 41, so that the threaded rod 41 is in a fixed state by the loading electric telescopic clamping block 57, and the loading drive motor 55 drives the loading spur gear 56 to rotate. At the same time, the loading spur gear 56 engages the spur tooth groove 420 to drive the front clamping block 42 to rotate forward, and the front clamping block 42 rotates along the threaded rod 41. The threaded structure moves toward the rear clamping block 44. When the front clamping block 42 is close to the front side surface of the magnetic column blank, the feeding drive motor 55 continues to drive the feeding spur gear 56 to drive the front clamping block 42 to move backward. At the same time, the two lower electric sliders 51 and the two upper electric sliders 53 respectively drive the two lower positioning blocks 52 and the two upper positioning blocks 54 to move backward with the front clamping block 42 until the front clamping block 42 pushes the magnetic column blank backward and is tightly pressed against the rear clamping block 44. At the same time, the rear clamping block 44 drives the compression spring 45 to be compressed backward. At this time, the compressed rear clamping block 44 pushes the rear clamping block 44 under the action of the reverse elastic force. The block 44 is close to the magnetic column blank, so that the rear clamping block 44 cooperates with the front clamping block 42 to firmly clamp the magnetic column blank through the anti-slip gasket 46 connected to it. After that, the two lower electric sliders 51 and the two upper electric sliders 53 respectively drive the two lower positioning blocks 52 and the two upper positioning blocks 54 to move away from the magnetic column blank. At the same time, the loading electric telescopic block 57 leaves the threaded rod 41, completing the automatic auxiliary loading of the magnetic column blank onto the clamping and rotating assembly, and making the axis of the magnetic column blank aligned with the axis of the front clamping block 42 and the rear clamping block 44 in the clamping and rotating assembly.

[0032] Then, the grinding working steps of the automatic grinding device for producing magnetic products of the present invention are carried out. The electric conveyor 3 drives the conveyor belt 31 to convey each clamping rotating assembly holding the magnetic column blank through the bottom of the grinding disk 61 of the electric grinder 6 in turn. Since the bottom of the grinding disk 61 is set to a downward contraction structure, the height of the middle area of ​​the bottom of the grinding disk 61 is higher than the height of the two side areas. In the process of the clamping rotating assembly driving the magnetic column blank through the two side areas of the bottom of the grinding disk 61, the bottom of the grinding disk 61 will not contact the magnetic column blank. Since the electric conveyor 3 needs to drive the conveyor belt 31 to convey each clamping rotating assembly to the loading rack 5 in turn, when other clamping rotating assemblies are aligned with the loading rack 5 for loading, the electric conveyor 3 needs to stop driving the conveyor belt 31 briefly to run. At this time, the straight tooth groove 420 of the front clamping block 42 in the clamping rotating assembly aligned with the middle area of ​​the bottom of the grinding disk 61 on the conveyor belt 31 is aligned with the mid-range spur gear 33, and the mid-range drive motor 32 drives the mid-range spur gear 33 to rotate, and the mid-range spur gear 33 engages with the straight tooth groove 420 to drive the front clamping block The block 42 rotates forward, and the middle area at the bottom of the grinding disc 61 grinds the rotating magnetic column blank in the clamping rotating assembly. Since the axis of the magnetic column blank is aligned with the axis of the front clamping block 42 and the rear clamping block 44 in the clamping rotating assembly, it is possible to ensure that the magnetic column blank is ground into a completely regular cylindrical structure. In addition, the conveyor belt 31 drives the magnetic column blank in the clamping rotating assembly into the middle area at the bottom of the grinding disc 61, and the conveyor belt 31 drives the magnetic column blank in the clamping rotating assembly out of the bottom of the grinding disc 61. During the process of moving outward from the intermediate area, the straight tooth groove 420 of the front clamping block 42 will engage with the corresponding straight rack 34, and the straight rack 34 engaging the straight tooth groove 420 will drive the front clamping block 42 and the entire clamping rotating assembly to rotate, so that the clamping rotating assembly drives the magnetic column blank to maintain a self-rotating state through the transition area between the middle area at the bottom of the grinding disk 61 and the two side areas, avoiding the excessive grinding of the magnetic column blank due to the continuous grinding of the same part of the stationary magnetic column blank by the grinding disk 61, and ending the automatic grinding process of the magnetic column blank.

[0033] Finally, the unloading step of the automatic grinding device for producing magnetic products of the present invention is carried out. The electric conveyor 3 drives the conveyor belt 31 to sequentially convey the magnetic column blanks that have completed the grinding process in each clamping and rotating assembly to the unloading rack 7. When the straight tooth groove 420 of the front clamping block 42 in the clamping and rotating assembly is aligned with the unloading spur gear 72, the unloading electric telescopic clamping block 73 extends outward to the slot 410 inserted into the threaded rod 41, so that the threaded rod 41 is fixed by the unloading electric telescopic clamping block 73, and the unloading drive motor 71 drives the unloading spur gear 72 to rotate, and at the same time, the unloading spur gear 72 engages the spur tooth groove 420 to drive the front clamping block 42 to rotate in the opposite direction, and the front clamping block 42 moves along the threaded structure of the threaded rod 41 toward the direction away from the rear clamping block 44 until the rear clamping block 44 and the front clamping block 42 loosen the magnetic column blank. After the magnetic column blank is loosened from the clamping rotating assembly, it falls onto the unloading slide 10 and slides outward. After that, the unloading electric telescopic clamping block 73 leaves the threaded rod 41, completing the automatic assistance of loading and unloading the magnetic column blank from the clamping rotating assembly.

[0034] Example 2, based on the above example 1, Figures 1-10 As shown, the electric conveyor 3 of this embodiment is fixedly connected to a spray pipe 8 in the middle portion thereof for spraying coolant upward toward the bottom of the grinding disc 61. The spray pipe 8 is externally connected to a coolant delivery device, and the coolant contains an antioxidant. A liquid storage chamber 6101 structure aligned with the spray pipe 8 is provided at the bottom of the grinding disc 61. A plurality of drainage grooves 6102 structures connected to the liquid storage chamber 6101 are provided at the bottom of the grinding disc 61, and all the drainage grooves 6102 surround the bottom edge of the liquid storage chamber 6101. When the electric grinder 6 drives the grinding disc 61 to rotate at high speed, the external coolant delivery device continuously sprays coolant toward the bottom of the grinding disc 61 through the spray pipe 8. After the coolant is sprayed into the liquid storage chamber 6101, The high-speed rotating grinding disc 61 drives the coolant in the liquid storage chamber 6101 to be thrown out to the periphery along the drainage grooves 6102, so that the coolant can be evenly distributed to various areas at the bottom of the grinding disc 61. After the bottom of the grinding disc 61 is moistened with the coolant, the heat generated by the grinding process of the magnetic column blank can be reduced, and the oxidation phenomenon caused by local high temperature of the magnetic column blank can be reduced. The antioxidant in the coolant can also further reduce the local oxidation phenomenon of the magnetic column blank; a drainage channel 30 structure is provided in the electric conveyor 3, and the coolant that falls on the electric conveyor 3 will be directly discharged outward through the drainage channel 30, avoiding the electric conveyor 3 from accumulating a large amount of coolant and affecting its own stable operation.

[0035] Example 3, based on the above Example 2, Figures 1-10As shown, a spray pipe 9 is installed on the unloading rack 7 of this embodiment, and the spray pipe 9 is externally connected to the passivation solution conveying equipment; after the conveyor belt 31 drives the magnetic column blank clamped by the front clamp block 42 and the rear clamp block 44 to move to align with the unloading rack 7, the unloading drive motor 71 first drives the unloading spur gear 72 to rotate at high speed, and at the same time, the unloading spur gear 72 engages with the spur tooth groove 420 of the corresponding front clamp block 42 to drive the front clamp block 42 and the rear clamp block 44 to rotate forward at high speed, and the high-speed rotating front clamp block 42 and the rear clamp block 44 drive the magnetic column blank to spin off the surface coolant at high speed, and then the unloading drive motor 71 The front clamping block 42 and the rear clamping block 44 are driven to rotate in a forward low speed. At the same time, the external passivation solution delivery equipment sprays the passivation solution onto the surface of the magnetic column blank that is rotating slowly at a low speed through the spray pipe 9, so that a passivation protective layer is formed on the surface of the magnetic column blank to avoid oxidation inside the magnetic column blank, so that the surface of the magnetic column blank remains in a completely regular cylindrical structure after grinding. Finally, the unloading drive motor 71 drives the unloading spur gear 72 to rotate in the opposite direction, so that the front clamping block 42 and the rear clamping block 44 jointly loosen the magnetic column blank, and at the same time the external passivation solution delivery equipment stops working.
