Detailed implementation manner

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0024] As Figure 1-3 shown, a workpiece table of a saw blade laser marking machine includes a frame, a rotating workpiece table 1, a manipulator 21, a loading table 22, and an unloading table 23. The center of the rotating workpiece table 1 is rotatably installed on the frame through a rotating connection mechanism. A magnetic suction chuck 2 is provided at each end of the rotating workpiece table 1. The manipulator 21 is rotatably connected to the frame. The loading table 22 and the unloading table 23 are arranged on the frame. It also includes two locking devices respectively arranged at both ends of the rotating worktable to control the magnetic suction chucks 2 at both ends, and a positioning device arranged below one side of the rotating worktable. The center of the rotating workpiece table 1 is rotatably installed on the frame through a rotating connection mechanism;

[0025] As Figure 2 shown, the locking device includes two symmetrically installed locking members 10. The middle parts of the two locking members 10 are rotatably installed on the rotating worktable through a rotating connecting member, and the heads of the two locking members 10 are connected by a return spring 11. The two ends of the return spring 11 are respectively connected to the two locking members 10. When the positioning device is not working, the locking devices on both sides hold the magnetic suction chuck 2 to prevent it from rotating;

[0026] As Figure 4-6As shown, the positioning device includes a positioning driving cylinder 12 and two L-shaped positioning members 13. The positioning driving cylinder 12 is provided with two output shafts, and each output shaft is connected to an L-shaped positioning member 13 by bolts. The two L-shaped positioning members 13 are symmetrically arranged inward. The positioning driving cylinder 12 is fixedly installed on the mounting plate 14. The positioning driving cylinder 12 inflates and deflates to adjust the lowering and lifting of the two L-shaped positioning members 13. When the L-shaped positioning members 13 on one side are lifted, the outer ends of the two locking members 10 of the locking device on the same side are pushed inward, and the inner ends of the locking members 10 do not press against the magnetic suction chuck 2. At this time, the magnetic suction chuck 2 can be adjusted to rotate;

[0027] It also includes a photoelectric switch for detecting the orientation of the saw blade. The photoelectric switch is not shown in the figure. As Figure 2 and 4 shown, the lower end of the magnetic suction chuck 2 is coaxially connected to a runner 15. The runner 15 is driven to rotate by a driving device. The driving device includes a driving motor 16 slidably connected to the mounting plate 14, a driving wheel 17 connected to the output shaft of the driving motor 16, and an adjusting cylinder 18 for adjusting the driving motor 16 to slide back and forth. The mounting plate 14 is provided with a slide rail 19. The driving motor 16 is slidably connected to the slide rail 19. The driving motor 16 is provided with a connecting plate 20. The telescopic end of the adjusting cylinder 18 is connected to the connecting plate 20. The adjusting cylinder 18 is fixedly installed on the mounting plate 14. The mounting plate 14 is fixedly connected to the machine frame. The driving device adjusts the orientation of the saw blade by driving the runner based on the signal of the photoelectric switch. When the rotating connection mechanism rotates the rotating workpiece table 1, the adjusting cylinder 18 pushes the driving motor 16 inward so that the driving wheel 17 does not contact the runner 15. After rotating half a circle, the driving motor 16 is pulled back, the driving wheel 17 contacts the rotation, and the positioning device opens the locking device for rotation adjustment to adjust the area to be marked of the workpiece to be processed placed on this side to the outside;

[0028] As Figure 2 shown, the rotating connection mechanism includes a bearing seat 8 and a rotating connection driving mechanism. The center of the rotating workpiece table 1 is connected to a rotating shaft by bolts. The rotating shaft is rotatably connected to the bearing seat 8. The bearing seat 8 is fixedly connected to the machine frame;

[0029] As Figure 3 shown, in one implementation, the rotating connection driving mechanism includes a rotating driving cylinder 3 fixed to the machine frame, a driving rack 7 connected to the telescopic end of the rotating driving cylinder 3, and a rotating gear 9 coaxially connected to the bottom of the rotating shaft. The rotating gear 9 meshes with the driving rack 7. The rotating driving cylinder 3 inflates and deflates to adjust the reciprocating telescoping of the driving gear, thereby driving the rotating gear 9 to drive the rotating workpiece table 1 to rotate. The marking machine is arranged on the side away from the positioning device;

[0030] In another embodiment, the rotation connection driving mechanism is a cam divider, and the rotating shaft is driven to rotate by the cam divider.

[0031] The structure of the present invention is simple and reasonably designed. The rotating workpiece table is a rotation platform with automatic control, which can realize marking work at one end and loading and unloading at the other end, with high work efficiency and saving working time. The two L-shaped positioning members of the positioning device fix the rotating workpiece table to prevent it from rotating. At the same time, the locking device on the same side as the positioning device is opened, and the driving device drives the magnetic suction chuck to rotate, adjusting the area to be marked of the workpiece to be processed placed on this side to the outside. The marking machine marks the workpiece on the other side, and the locking device on the other side fixes the magnetic suction chuck to prevent it from rotating.

[0032] The above are only the preferred embodiments of the present invention, and the present invention is not limited to other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
