[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes:

[0027] The support frame 1 is fixed on the ground, and several positioning rings 2 are fixed on the crossbar of the support frame 1. Several openings 3 are opened at equal angles on the ring wall of the positioning ring 2. The position of the positioning ring 2 is fixed by the support frame 1, so that the core shank can be inserted into the positioning ring 2.

[0028] Positioning block 4, there are several positioning blocks 4, and they are slidably disposed in the opening 3. Tightening component 5 is disposed on positioning ring 2, and tightening component 5 is engaged with the corresponding positioning block 4. Adjusting the position of positioning block 4 makes it easier to restrict the core shank of different diameters within positioning ring 2.

[0029] Rolling shaft 6, there are several rolling shafts 6, and they are respectively screwed to the central positioning block 4 by rotating rods. Several grinding blocks 7 are respectively set on the positioning blocks 4 on the left and right sides. The rolling shaft 6 contacts the annular wall of the core handle and controls the rotation and left and right movement direction of the core handle. The grinding blocks 7 contact the core handle and polish the surface of the core handle to remove burrs. The inner end of the positioning blocks 4 on the left and right sides is provided with a slot 19. The grinding blocks 7 are set in the slot 19 by bolts, which facilitates timely replacement of the grinding blocks 7 and ensures the grinding and polishing effect.

[0030] Two motors 8 are respectively fixed in the two corresponding positioning blocks 4 in the middle, and the output end of the motor 8 is connected to the end of the rolling shaft 6. The motor 8 is connected to an external power supply and controls the rotation direction of the corresponding rolling shaft 6 through the motor 8.

[0031] The grinding shaft 9 is movably inserted into the guide rod on the left side of the support frame 1. The two ends of the spring 10 are respectively connected to the support frame 1 and the end of the grinding shaft 9. The grinding shaft 9 contacts the inner wall of the core shank and deburrs the inside of the core shank. A protective ring 20 is sleeved on the left end of the grinding shaft 9, and an anti-wear layer 21 is provided on the protective ring 20. The position of the end of the core shank is restricted by the protective ring 20.

[0032] Tightening component 5 includes:

[0033] Guide rod 11, there are several guide rods 11, and they are fixed at equal angles on the ring wall of positioning ring 2. Several adjusting blocks 12 are movably inserted on the guide rod 11. One of the adjusting blocks 12 is screwed with an adjusting ring 13 by bearing. The adjusting ring 13 is screwed onto the guide rod 11. The adjusting ring 13 controls the movement of the corresponding adjusting block 12 on the guide rod 11. Limiting rings 17 are fixed at the ends of the several guide rods 11. The limiting rings 17 are set to cooperate with the adjusting blocks 12 to restrict the position of the adjusting blocks 12 and prevent the adjusting blocks 12 from detaching from the guide rod 11.

[0034] Connecting blocks 14, there are several connecting blocks 14, and they are respectively fixed on the corresponding positioning blocks 4. The two ends of several connecting plates 15 are respectively screwed to the connecting blocks 14 and the adjusting blocks 12 by hinge seats. The rotation of the connecting plates 15 is controlled by the adjusting blocks 12, thereby controlling the position of the positioning blocks 4 in the opening 3. The wing plates of the several positioning blocks 4 are provided with abutting shafts 18. The abutting shafts 18 are set to abut against the connecting plates 15. The abutting shafts 18 are made of galvanic material, which protects the connecting plates 15 to a certain extent.

[0035] Spring 16, there are several springs 16, and their two ends are respectively connected to the wing plate in the positioning block 4 and the ring wall of the positioning ring 2. The positioning block 4 is reset by the elastic force of the spring 16.

[0036] When using this utility model, the operator first inserts the core shank into several positioning rings 2, so that the grinding shaft 9 is inserted into the core shank. Then, the operator rotates the adjusting ring 13 to control the adjusting block 12 to move on the guide rod 11. The adjusting block 12 controls the connecting block 14 to move using the connecting plate 15. The connecting block 14 controls the positioning block 4 to move within the opening 3, so that the rolling shaft 6 and the grinding block 7 move to the appropriate position. Then, the operator starts the motor 8 to control the rotation of the rolling shaft 6. The rolling shaft 6 drives the core shank to rotate and move left and right, so that the grinding block 7 polishes the ring wall of the core shank. At the same time, when the core shank rotates, the inner wall of the core shank contacts the grinding shaft 9, thereby deburring the inner wall of the core shank. When the core shank moves to the left, the end of the core shank abuts against the protective ring 20 to protect the end of the core shank.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] The rotation of the rolling shaft 6 is controlled by the motor 8, thereby controlling the rotation and movement direction of the core shank. In conjunction with the grinding block 7 and the grinding shaft 9, the core shank is simultaneously polished and deburred.

[0039] The tightening component 5 is set up, and the position of the adjusting block 12 is controlled by the adjusting ring 13. In conjunction with the connecting plate 15, the position of the positioning block 4 is controlled, which makes it easier to grind the core shank of different sizes.

[0040] A limit ring 17 is set to restrict the adjusting block 12 to the guide rod 11, so as to prevent the adjusting block 12 from detaching from the guide rod 11.

[0041] The slot 19 is designed to facilitate timely replacement of the polishing block 7, ensuring the polishing effect of the polishing block 7 on the ring wall of the core shank.

[0042] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
