Description

Technical Field

[0001] The utility model relates to the technical field of hardware product processing, in particular to an inner tube grinding device for processing round tube hardware products. Background Art

[0002] Hardware products are auxiliary and accessory products used in daily life and industrial production. Early hardware was primarily made of metals such as gold, silver, copper, iron, and tin, hence the name. Today, in addition to various metals, non-metallic materials such as plastic and fiberglass are also widely used. During the production process of metal round tubes, some require a grinding device to polish the inner surface of the tube to ensure that the tube meets production requirements.

[0003] When the existing metal round tube inner tube grinding device is grinding a long round tube, the grinding head is small in size, and the grinding motor and the grinding shaft need to be pushed to move along the inner side of the round tube while grinding, which makes the grinding process take more time and reduces the grinding efficiency. Utility Model Content

By arranging the grinding shaft, keyway, inner sleeve, grinding wheel and fastening nut, a longer grinding wheel is provided on the outer side of the grinding shaft. When grinding the inner side surface of the long round tube, the grinding wheel directly extends into the inner side surface of the round tube. The grinding motor drives the grinding shaft and the grinding wheel to rotate rapidly, and then the inner side surface of the metal tube is polished as a whole at the same time. There is no need to move the grinding head while grinding, which reduces the grinding time and can effectively solve the problems in the background technology.

[0023] like Figures 1-4 As shown, the No. 2 servo motor 10 drives the rotation of the screw, providing power for the sliding block 8 to move up and down along the guide column 3, so that the sliding block 8 and the support plate 12 move up and down along the screw through the screw bearing seat 19, and the guide column 3 ensures the stability of the sliding block 8 moving up and down.

[0024] The lower end of the support frame 9 is welded to the base 1, a screw rod is provided at the output end of the No. 2 servo motor 10, and the guide column 3 and the sliding block 8 are connected through a sliding bearing.

Multiple grinding wheels 17 are connected together with hexagon socket screws, and then tightened on the grinding shaft 13 with the fastening nut 16, and the inner sleeve 18 is clamped and fixed to ensure the stability of the grinding wheel 17. Then, according to the diameter and thickness of the metal sleeve, the forward and reverse screw rods 4 are driven to rotate by the No. 1 servo motor 2, so that the distance between the two sliding seats 5 is adjusted, and then the distance between the support roller 6 and the driving roller 15 is adjusted, which can stably support the metal round tube. After the spacing is adjusted, After the metal pipe passes through the grinding wheel 17, it is placed on the support roller 6 and the drive roller 15. The No. 2 servo motor 10 drives the screw to rotate, so that the sliding block 8 moves downward along the guide column 3, so that the grinding wheel 17 can be pressed on the inner bottom side of the metal pipe. The drive motor 7 is started to rotate the drive roller 15, and then the metal pipe is rotated. The grinding motor 11 drives the grinding wheel 17 to rotate in the opposite direction of the rotation direction of the metal pipe, so that the grinding wheel 17 grinds the inner side of the metal pipe. The operating width of the grinding wheel 17 exceeds the length of the metal pipe, so that the grinding device does not need to move the grinding wheel while grinding, which reduces the grinding time and improves the grinding efficiency.
