[0079] The working principle of this utility model:

[0080] 1. At least two drive shafts 12 drive the workpiece to rotate, which is suitable for use when processing standard cylindrical workpieces.

[0081] 1. Adjust the gap between at least two drive shafts 12 according to the size of the workpiece.

[0083] 2. The driving mechanism 13 drives at least two driving shafts 12 to rotate in the same direction synchronously through the rotating motor 131 and the first conveyor belt 132, so that at least two driving shafts 12 provide rotational support for the workpiece.

[0084] Second, the synchronous chuck mechanism 14 drives the workpiece to rotate, and processes a cylindrical workpiece with a small length or cross-section, or a workpiece with a ring-shaped cross-section.

[0085] 1. The workpiece is sleeved / inserted on the synchronous chuck mechanism 14. The workpiece can be an annular structure, or a cylindrical workpiece with a smaller cross-sectional diameter.

[0086] If the cross-sectional diameter of the workpiece is small and is a long cylindrical structure, the positioning posts 1432 in this embodiment are provided with at least two groups and are distributed in a circular array, so that the workpiece can be inserted and fixed in the middle of at least two positioning posts 1432 .

[0087] For a workpiece with an annular cross section, first move the positioning column 1432 to extend into the workpiece with an annular structure. The workpiece with an annular structure can be an annular structure such as a ring, or a cup body with a hollow cylindrical structure having an opening at the end.

[0088] 2. Drive the rotating motor 131 to synchronously drive the disc assembly 143 to rotate through the second conveyor belt 132, so that the positioning column 1432 clamps the workpiece for rotational driving, avoiding deformation of the annular structure workpiece during rotation, and improving the practicality of the roller device structure.

[0089] The auxiliary roller device for laser engraving is provided with a synchronous chuck mechanism 14, and the positioning column 1432 can be plugged and fixed with the annular workpiece. On the basis of supporting the cylindrical structure workpiece, it can also support the annular structure workpiece, thereby improving the practicality of the roller device structure.

[0090] 3. On the basis of the synchronous chuck mechanism 14 driving the workpiece to rotate, an axial push mechanism 16 is provided to fix the axis of the workpiece, which is suitable for processing solid cylindrical workpieces with a large length, such as a cup body.

[0091] The center of the push plate 162 of the axial push mechanism 16 corresponds to the axis position of the rotating disk 1431. When in use, the push seat 161 slides relative to the first slide groove 112 on the base 11, so that the push plate 162 is fitted and fixed to the axis of the workpiece away from the synchronous chuck mechanism 14. Then, the push plate 162 is fastened to the base 11 by the first fastener 163, so that the push plate 162 and the rotating disk 1431 clamp and fix the two ends of the workpiece.

[0092] 4. Remove the second conveyor belt 133, and the drive shaft 12 and the synchronous chuck mechanism 14 can synchronously drive a workpiece with a larger cross-section and a ring-shaped structure; wherein the drive mechanism 13 drives at least two drive shafts 12 to rotate in the same direction synchronously with the first conveyor belt 132 through the rotating motor 131, so that at least two drive shafts 12 support the outer wall of the ring-shaped workpiece and drive the rotation.

[0093] At the same time, the disc assembly 143 is driven to rotate, and the positioning column 1432 clamps the workpiece to drive it to rotate, thereby preventing the annular structure of the workpiece from deforming during rotation, improving the practicality of the roller device structure, further improving the rotation efficiency of the workpiece, and improving the stability of the rotation of the annular workpiece.

[0094] The laser engraving auxiliary roller device uses the positioning column 1432 to position the annular workpiece, and synchronously clamps the workpiece on the basis of driving the annular workpiece using at least two driving shafts 12, thereby improving the stability of the auxiliary roller device in the process of driving the annular workpiece to rotate.

[0095] This completes the use process of the laser engraving auxiliary roller device with a synchronous chuck mechanism of the preferred embodiment.

[0096] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
