A plurality of threaded holes 21 are uniformly and spacedly arranged on the placing platform 2. The threaded holes 21 are used for connecting the positioning bolts 211. The laser marking head 13 is used for performing laser marking on the marking piece 5 on the placing platform 2.

[0031] With reference to Figure 1 , according to the shape and size of the marking piece 5 to be machined, the position is determined first, and then the positioning bolt 211 is installed in the corresponding threaded hole 21. The positioning bolt 211 can be abutted by the marking piece 5, and the end of the positioning bolt 211 can also be abutted on the top surface of the marking piece 5. The marking piece 5 is pressed on the placing platform 2, and the marking piece 5 is positioned. More shapes of the marking piece 5 can be adapted, and the application range of the laser marking machine is expanded.

[0032] With reference to Figure 1 , the driving member one can be a combination of a motor and a lead screw or an air cylinder. In the drawings of the application, the motor and the lead screw are adopted to drive the lifting platform 12. The motor is arranged at the top end of the stand column 11. The output shaft of the motor is vertically arranged downward and coaxially fixed on the lead screw. The lifting platform 12 slides in the vertical direction on the stand column 11. The lead screw is threadedly connected to the lifting platform 12. The driving member two is a stepping motor or a servo motor. The motor is arranged in the lifting platform 12. The output shaft of the motor horizontally extends to the side of the placing platform 2 and is fixed on the laser marking head 13.

[0033] With reference to Figure 1 andFigure 2 Further comprising a driving member three and a three-jaw chuck 3, the driving member three is arranged on the workbench 1, and the output end of the driving member three is arranged on the three-jaw chuck 3, and is used to drive the three-jaw chuck 3 to rotate along the vertical axis direction, the three-jaw chuck 3 is located outside the placing table 2, and after the laser marking head 13 rotates to the side facing the three-jaw chuck 3, the three-jaw chuck 3 is used for marking the outer circumferential surface of the annular marking piece 5 clamped thereon.

[0034] With reference to Figure 1 and Figure 2 , the three-jaw chuck 3 is more suitable for clamping some cylindrical or annular marking pieces 5, the driving member two drives the rotating table to rotate, the laser marking head 13 is driven to the side facing the three-jaw chuck 3, then the lifting table 12 moves to the appropriate position, and the outer wall of the marking piece 5 clamped by the three-jaw chuck 3 can be marked, and the three-jaw chuck 3 is driven to rotate by the driving member three, so that the three-jaw chuck 3 drives the marking piece 5 to rotate, and the circumferential outer wall of the marking piece 5 can be marked.

[0035] With reference to Figure 1 and Figure 2 , the driving member three is a stepping motor or a servo motor, the motor is arranged in the workbench 1, and the output shaft of the motor vertically extends upward and is fixed coaxially on the three-jaw chuck 3.

[0036] With reference to Figure 2 and Figure 3 , the three-jaw chuck 3 is detachably provided with an extension rod 32 on the claw 31, the bottom end of the extension rod 32 is locked on the inner end of the claw 31 through a bolt, the extension rod 32 is vertically arranged, and the extension rod 32 is used for abutting against the inner circumferential surface of the annular marking piece 5. The marking piece 5 can be stacked, and in the process of opening the three-jaw chuck 3, the three extension rods 32 are synchronously opened and abut against the inner circumferential surface of the annular marking piece 5, and by changing the height position of the laser marking head 13 through the lifting table 12, more annular marking pieces 5 can be marked at one time.

[0037] With reference to Figure 2 and Figure 3 , further comprising a counterweight 4, the counterweight 4 is arranged in a hemispherical shape, a containing groove 14 for placing the counterweight 4 is formed on the top surface of the workbench 1, the top surface of the counterweight 4 is horizontally arranged and is hingedly provided with a handle 41, the counterweight 4 is used for abutting against the top ends of the three extension rods 32, the bottom end of the counterweight 4 is located between the three extension rods 32, and the outer wall of the counterweight 4 abuts against the inner wall of the top end of the extension rod 32.

[0038] With reference to Figure 2 and Figure 3 , the counterweight 4 acts on the top end of the extension rod 32, has a tendency to outwardly spread the top end of the extension rod 32, can make the extension rod 32 better abut against the inner wall of the annular marking piece 5, so that when the three-jaw chuck 3 rotates, all the annular marking pieces 5 can be synchronously driven to rotate.

[0039] Reference Figure 2 and Figure 3 An arc groove 322 matching the outer arc surface of the counterweight 4 is formed on the inner wall of the top end of the extension rod 32. The contact between the arc groove 322 and the outer arc surface of the counterweight 4 increases the contact area between the counterweight 4 and the extension rod 32, thereby improving the stability of the counterweight 4 when placed at the top of the three extension rods 32.

[0040] Reference Figure 2 and Figure 3 When the three-jaw chuck 3 is in the retracted state, adjacent extension rods 32 abut against each other. This abutment between the extension rods 32 improves their strength and stability.

[0041] Reference Figure 2 and Figure 3 Elastic friction strips 321 are arranged at intervals along the vertical direction on the outer wall of the extension rod 32. The elastic friction strips 321 are made of silicone or rubber material. When the elastic friction strips 321 abut against the inner wall of the annular marking part 5, they can deform, thereby better fitting with the inner wall of the marking part 5 and increasing the friction between them.
