[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: Please refer to the attached Figure 1 to the attached Figure 6, this embodiment provides a grinding machine for rough grinding of metal bulk materials, including a corresponding material carrying device 1 and a multi-axis rough grinding device 2. The material carrying device 1 includes a carrying platform 11 that moves back and forth. The multi-axis rough grinding device 2 includes a grinding wheel assembly 3 and a multi-axis driving assembly 4 that drives the grinding wheel assembly 3 to move axially along the coordinate axes. The multi-axis driving assembly 4 includes a rotary driver 41 connected to the grinding wheel assembly 3. The grinding wheel assembly 3 includes a first grinding wheel 31, a second grinding wheel 32, a grinding wheel loading frame 33, a grinding wheel off-axis mechanism 34, and a grinding wheel lifting mechanism 35. The grinding wheel off-axis mechanism 34 includes a first docking member 341 and a second docking member 342 disposed between the first grinding wheel 31 and the second grinding wheel 32. The first docking member 341 and the second docking member 342 can be snapped or disengaged from each other radially. One side of the first grinding wheel 31 away from the second grinding wheel 32 is connected to the output end of the rotary driver provided in the multi-axis driving assembly 4. The first grinding wheel 31 and the second grinding wheel 32 are arranged in combination. When the first docking member 341 is snapped onto the second docking member 342, the rotation of the first grinding wheel 31 driven by the rotary driver can drive the synchronous rotation of the second grinding wheel 32. The grinding wheel lifting mechanism 35 includes a lifting connecting shaft 351 movably disposed between the second grinding wheel 32 and the grinding wheel loading frame 33. One end of the lifting connecting shaft 351 is inserted into the side of the second grinding wheel 32 away from the first grinding wheel 31. When the lifting connecting shaft 351 moves away from the carrying platform 11, it can drive the second grinding wheel 32 to move radially, causing the first docking member 341 and the second docking member 342 to disengage from each other, thereby releasing the linkage between the first grinding wheel 31 and the second grinding wheel 32. At this time, the second grinding wheel 32 moves away from the carrying platform 11, thus reducing the grinding width of the grinding wheel assembly 3. In the grinding machine for rough grinding of metal bulk materials in this embodiment, the first grinding wheel 31 and the second grinding wheel 32 arranged in combination in the grinding wheel assembly 3 are used as a grinding wheel set with an adjustable grinding width loaded in the grinding wheel loading frame 33. Then, the grinding wheel off-axis mechanism 34 is used to achieve the effect of the first grinding wheel 31 and the second grinding wheel 32 being able to be misaligned and separated, and after separation, the second grinding wheel 32 will not interfere with the rotation of the first grinding wheel 31. Based on this, combined with the driving effect of the grinding wheel lifting mechanism 35, the second grinding wheel 32 is driven to shift. At this time, the output end of the rotary driver 41 can only drive the first grinding wheel 31 to rotate, and the first grinding wheel 31 will not drive the second grinding wheel 32 to rotate. It is possible to adjust the grinding width of the grinding wheel assembly 3 without disassembling and replacing any grinding wheels, improving the processing efficiency of metal bulk materials with different specifications.

[0027] The first docking member 341 is elliptical, and two opposite first abutting surfaces 3411 are provided on both circumferential sides thereof. The second docking member 342 is wrench-shaped, and two opposite second abutting surfaces 3421 are provided on its inner sides. When the first docking member 341 is clamped to the second docking member 342, the first abutting surface 3411 abuts against the corresponding second abutting surface 3421. Preferably, the second docking member 342 is provided with a mating port 3422 for the first docking member 341 to be radially clamped or disengaged. When the first docking member 341 is docked with the second docking member 342, the mating port 3422 of the second docking member 342 surrounds the first docking member 341, and the opposite first abutting surfaces 3411 respectively abut against the corresponding second abutting surfaces 3421, so that the first grinding wheel 31 and the second grinding wheel 32 form a grinding wheel assembly 3 that can rotate synchronously.

[0028] The grinding wheel off-axis mechanism 34 further includes an auxiliary thrust bearing 343 coaxially arranged with the first grinding wheel 31. One axial side of the auxiliary thrust bearing 343 is fitted into the first grinding wheel 31, and the side of the auxiliary thrust bearing 343 axially away from the first grinding wheel 31 frictionally abuts against the second grinding wheel 32. The function of the auxiliary thrust bearing 343 is: after the second grinding wheel 32 moves off-axis, the side of the auxiliary thrust bearing 343 that fits against the second grinding wheel 32 continuously abuts against the second grinding wheel 32. At the same time, when the first grinding wheel 31 starts to rotate, the side of the auxiliary thrust bearing 343 that fits against the first grinding wheel 31 rotates to reduce the frictional interference between the rotating first grinding wheel 31 and the stationary second grinding wheel 32.

[0029] The grinding wheel off-axis mechanism 34 further includes an auxiliary centripetal bearing 344 coaxially arranged with the second grinding wheel 32. One axial side of the auxiliary centripetal bearing 344 is fitted into the second grinding wheel 32, and the inner side surface of the auxiliary centripetal bearing 344 faces the mating port 3422, and can be used to abut against the first docking member 341 that disengages from the second docking member 342. The function of the auxiliary centripetal bearing 344 is: after the second grinding wheel 32 moves off-axis, the first docking member 341 disengages from the second docking member 342, and then the first docking member 341 abuts against the inner side of the auxiliary centripetal bearing 344. When the first grinding wheel 31 starts to rotate, the frictional interference between the rotating first docking member 341 and the stationary second grinding wheel 32 is reduced.

[0030] The grinding wheel lifting mechanism 35 further includes a coupling sleeve 352 and a lifting locking kit 353. The coupling sleeve 352 includes a collar 3521 and a slider 3522. The collar 3521 is sleeved on the lifting coupling shaft 351. The lifting locking kit 353 is used to drive the slider 3522 to move away from or close to the bearing platform 11. Further, oppositely arranged slide rail strips 331 are provided on the grinding wheel loading frame 33, and the opposite sides of the slider 3522 can be slidably clamped on the slide rail strips 331. Further, a lifting drive gear 332 is rotatably provided on the grinding wheel loading frame 33, and a lifting rack 3523 extending in the height direction is provided on the slider 3522. The lifting drive gear 332 meshes with the lifting rack 3523 to rotationally drive the lifting of the slider 3522. Preferably, the lifting locking kit 353 is a ratchet locking structure provided between the lifting drive gear 332 and the grinding wheel loading frame 33. A turntable handle 333 coaxially connected to the lifting drive gear 332 is also rotatably provided on the grinding wheel loading frame 33. The function of the grinding wheel lifting mechanism 35 with the above structure is to drive the rotation of the lifting drive gear 332 through the rotation of the turntable handle 333. Through meshing with the lifting rack 3523, the slider 3522 is driven to slide along the height direction of the slide rail strip 331, so that the collar 3521 sleeving the lifting coupling shaft 351 rises, driving the lifting coupling shaft 351 to rise. The lifting coupling shaft 351 then drives the inserted second grinding wheel 32 to rise, so that the first docking member 341 and the second docking member 342 are separated from each other, completing the off-axis movement of the second grinding wheel 32 from the first grinding wheel 31. Finally, the rotation of the lifting drive gear 332 is locked by the ratchet locking structure, so as to maintain the off-axis state of the second grinding wheel 32.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
