[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A device for rough grinding the outer circle of a workpiece comprises a support frame 2, a grinding roller 1 is rotatably arranged at the top edge position of the support frame 2, a right-angle folding rod 9 is symmetrically fixedly arranged at the top edge position of the support frame 2, an intermediate box 13 is fixedly arranged at the end of the right-angle folding rod 9, a center pipe 12 is fixedly arranged on the top of the intermediate box 13, the center pipe 12 needs to be connected to an external cleaning water source, and dust reduction pipes 14 are equidistantly arranged at the bottom of the intermediate box 13, and the dust reduction pipes 14 have a thinner diameter.

[0021] The front and rear sides of the middle box 13 are rotatably connected with a top grinding roller 7, the support frame 2 is fixedly provided with an arc slope 8 between the two groups of grinding rollers 1, and the arc slope 8 is provided with a feeding assembly for feeding round rods into between the grinding rollers 1, and a recovery bucket 5 is fixedly provided at the bottom of the support frame 2, and a valve is provided at the bottom of the side of the recovery bucket 5 to control the recovery bucket 5 to drain water.

[0022] The feeding assembly includes a guide frame 6, a support folding rod 15, and a push plate 11. The guide frame 6 is fixedly arranged on the top of the middle box 13. The support folding rod 15 is movably inserted into the side of the guide frame 6. The push plate 11 is fixedly arranged at the bottom of the support folding rod 15. The bottom of the push plate 11 contacts the top of the arc slope 8. An auxiliary handle 10 is fixedly arranged on the side of the support folding rod 15. The worker manually pushes the right-angle folding rod 9 to send the circular piece between the two groups of grinding rollers 1 through the push plate 11. Since the circular piece will rotate when being ground between the two groups of grinding rollers 1, the push plate 11 prevents the rotating circular piece from contacting the worker's hand.

[0023] The rotating shaft of the grinding roller 1 is fixedly connected to one end of the belt transmission structure 4, and the other end of the belt transmission structure 4 is fixedly connected to the output end of the driving motor 3. The driving motor 3 is fixedly connected to the side of the support frame 2. The diameter of the two sets of grinding rollers 1 is much larger than the diameter of the top grinding roller 7. The height of the center line of the two sets of grinding rollers 1 is higher than the top height of the arc slope 8. Therefore, when the circular part is fed between the two sets of grinding rollers 1, the outer wall of the circular part will contact the side walls of the two sets of grinding rollers 1.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] The worker starts the driving motor 3, which drives the two groups of grinding rollers 1 to rotate through the belt transmission structure 4, and connects the middle box 13 to a water source such as a faucet through the central tube 12, and then places the circular workpiece on the top of the arc slope 8. Finally, by holding the auxiliary handle 10, the pushing plate 11 is driven to approach the two groups of grinding rollers 1 through the right-angle folding rod 9, and the pushing plate 11 sends the circular workpiece between the two groups of grinding rollers 1 and the top grinding roller 7. The multiple groups of dust reduction pipes 14 at the bottom of the middle box 13 spray cooling water on the outer wall of the circular workpiece, and the cooling water carries the waste dust and waste chips into the recovery bucket 5.

[0026] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
