Examples

Referring to fig. 1-7, the centering and clamping device for the eccentric roller of the cylinder sleeve comprises a rotating shaft 1, a sleeve 2 is coaxially arranged outside the rotating shaft 1, three through holes 3 are uniformly formed in the side wall of the sleeve 2 along the circumferential direction, an eccentric chute 4 is arranged on the rotating shaft 1 corresponding to the through holes 3, a clamping roller 5 is arranged between the eccentric chute 4 and the sleeve 2, the clamping roller 5 penetrates through the through holes 3, and an eccentric arc-shaped surface 6 abutted against the clamping roller 5 is arranged on the eccentric chute 4. In this embodiment, the eccentric inclined groove 4 is formed at the top of the rotating shaft 1, an accommodating space for accommodating the clamping roller 5 is formed between the eccentric inclined groove 4 and the inner side wall of the sleeve 2, and the distance between the eccentric arc-shaped surface 6 and the inner side wall of the sleeve 2 is gradually reduced from one side, so that when the rotating shaft 1 rotates, the eccentric arc-shaped surface 6 presses the clamping roller 5 and the clamping roller 5 moves outward.

The rotating shaft 1 is provided with a placing table 7 for placing the cylinder sleeve, and the sleeve 2 is arranged on the placing table 7.

The rotating shaft 1 is rotatably connected to a turntable bearing seat 8.

The rotating shaft 1 is connected with a rotating motor 9.

The through-hole 3 comprises an outer opening on the outer side wall of the sleeve 2, the size of which is larger than the outer diameter of the clamping roller 5, and an inner opening on the inner side wall of the sleeve 2, the size of which is smaller than the outer diameter of the clamping roller 5. The size of the outer opening is larger than the outer diameter of the clamping roller, so that the clamping roller can extend out of the sleeve as far as possible, the cylinder sleeves with different inner diameters are clamped and fixed, and the adaptability and the universality are improved; the size of the inner opening is smaller than that of the clamping roller 5, so that the clamping roller 5 cannot be extruded out of the sleeve 2, and the clamping roller 5 cannot be separated from the through hole 3 due to the blocking of the eccentric arc-shaped surface 6, thereby ensuring the normal use of the device.

The working principle is as follows: when the device is used, the cylinder sleeve 10 is placed on the placing table 7, the cylinder sleeve 10 is sleeved on the outer side of the sleeve 2, the rotating shaft 1 is driven to rotate by rotating the motor 9, the eccentric arc-shaped surface 6 of the eccentric chute 4 extrudes the clamping roller 5, the clamping roller 5 moves outwards and clamps the cylinder sleeve 10, and therefore centering and clamping of the cylinder sleeve 10 are achieved; after the cylinder sleeve 10 is machined, the cylinder sleeve 10 can be taken down only by reversely rotating the rotating shaft 1.

The foregoing description of the embodiments of the invention has been presented for purposes of illustration and not limitation, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the illustrated embodiments.
