In one embodiment, the seventh driving element is a divergence angle adjusting motor, if the laser marking system judges that the surface of the revolving body workpiece has a protrusion by comparing the signal transmitted from the outer diameter detector 500, the laser marking system controls the seventh driving element to drive the divergence angle adjusting lens to move forward, so that the divergence angle of the laser beam entering the laser marking head is reduced, and the working distance of the laser marking head is reduced to adapt to the change of the outer diameter of the revolving body product; if the laser marking system judges that the surface of the revolving body workpiece has the depression, the laser marking system controls the seventh driving piece to drive the divergence angle adjusting lens to move backwards, so that the divergence angle of a laser beam entering the laser marking head is increased, the working distance of the laser marking head is increased, the outer diameter of the revolving body product is adapted to change, and the laser processing precision of the laser marking device on the revolving body workpiece 200 is further ensured.
According to the workpiece placing table and the laser marking device, the structures and positions of the fixing part, the supporting seat and the first driving part and the mutual connection among the fixing part, the supporting seat and the first driving part are reasonably arranged, so that a revolving body workpiece can be stably and accurately positioned on the workpiece placing table, and the height of the supporting wheel can be adjusted according to the outer diameter of the supported part of the revolving body workpiece by arranging the height adjusting assembly on the supporting seat, so that the workpiece placing table and the laser marking device can adapt to complicated revolving body workpieces with multiple sections of different outer diameters; in addition, in the rotating machining process of the rotating body workpiece, the supporting seat is in point contact with the outer surface of the rotating body workpiece all the time, the workpiece can be prevented from being over-defined, and the workpiece is prevented from being deformed, twisted or loosened due to over-defined installation in the rotating machining process. In addition, the supporting wheel can rotate along with the revolving body workpiece in the rotary machining process, and by the design, the revolving body workpiece can be driven to rotate only by applying smaller rotary torque force to the fixing piece through the first driving piece, so that the workpiece can be prevented from being deformed, distorted or loosened due to overlarge rotary torque force in the rotary machining process, and the laser machining precision of the laser marking equipment on the revolving body workpiece can be improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
