It is necessary to grind to make the outer diameter of the cylinder consistent and smooth. In the prior art, it is generally performed by manually holding a grinding device or using a fixed-size grinding device to grind the outer surface of the cylinder product. During the grinding work, the cylinder needs to be clamped and driven to rotate to allow the grinding mechanism to perform the grinding work. Utility Model Content

In the utility model, the rotation axes of the driving roller 3 and the driven roller 4 are parallel to each other, and when the two brackets 2 approach each other, the driving roller 3 and the driven roller 4 can be driven to approach each other, and at this time the cylinder can be supported at two points, and at this time the auxiliary roller mechanism 5 moves and changes its position to form a triangular support for the cylinder, and at this time the driving roller 3 rotates to drive the cylinder to rotate, and at this time, when used in conjunction with the grinding device, the grinding device can fit the outer surface and inner surface of the cylinder for grinding.

[0020] Furthermore, the interval between the driven roller 4 and the driving roller 3 is smaller than the diameter of the cylinder, so as to prevent the cylinder from falling from the gap between the driven roller 4 and the driving roller 3, and then the auxiliary roller mechanism 5 is used to fix the cylinder in accordance with different sizes.

[0021] Furthermore, in the utility model, the driving roller, the driven roller and the auxiliary roller all use rubber rollers with relatively large friction force, and the cylinder is supported as a whole, so as to avoid the occurrence of spiral lines during rotation.

The bracket 2 is connected to the sliders 62. In the present invention, the bracket 2 realizes the sliding effect by means of the screw rods 61 and the sliders 62. Furthermore, the bracket 2 can also realize the sliding effect by installing a cylinder. At the same time, in the present invention, a gear is mounted on the end of the screw rod 61, and the gear can be driven to rotate by a chain.

The sliding direction of the stand 82 relative to the base 81 is parallel to the rotation axis of the driving roller 3, and the movement of the stand 82 can change the position of the auxiliary roller 53 in the direction of the cylinder axis; further, in the utility model, the auxiliary roller mechanism 5 can squeeze the cylinder to fit the driving roller 3, increase the friction force, and allow the cylinder to be driven by the driving roller 3.

[0025] In a specific implementation manner, refer to Figure 1 , Figure 2 A second driving mechanism 84 is installed on the stand 82, and the second driving mechanism 84 is connected to the support arm 83. The second driving mechanism 84 is used to drive the support arm 83 to slide toward the cylinder and squeeze the cylinder so that the cylinder can be fixed on the driving roller 3. The second driving mechanism 84 is a cylinder in the prior art.

[0026] In a specific implementation manner, refer to Figure 1 , Figure 2 The auxiliary roller mechanism 5 includes a U-shaped member 51, a triangular member 52 and an auxiliary roller 53.
