[0019] See also Figure 1 and Figure 2The rotary positioning platform 3 is provided with a turntable 5, a servo motor 4, and a rotating shaft 16. The turntable 5 obtains the rotating power provided by the servo motor 4 through the rotating shaft 16. A plurality of positioning rods 6 in a circular array are axially arranged on the outer periphery of the turntable 5. A bearing seat 15 is arranged between the positioning rods 6 and the turntable 5, so that the positioning rods 6 and the rotating shaft 16 can rotate freely while maintaining parallelism. The positioning rods 6 are sleeved to fit the metal pipe material to be laser marked.

[0020] See also Figure 1 and Figure 2 The sliding and pressing platform is provided with a sliding platform 14, a sliding frame 11 and a pressing assembly. A slider rail assembly 13 is provided between the sliding platform 14 and the sliding frame 11. A telescopic cylinder 2 parallel to the slider rail assembly 13 is also provided horizontally between the sliding frame 11 and the sliding platform 14 to drive the sliding frame 11 to slide horizontally relative to the sliding platform 14, thereby adjusting the distance between the sliding frame 11 and the rotating positioning platform 3. A pressing assembly is provided on the sliding frame 11 facing the turntable 5.

[0021] See also Figure 1 and Figure 2 The clamping assembly includes a rotating motor 10, a spline sleeve rod 8, a spline sleeve 9 and a rubber pressure block 7. The rotating motor 10 is connected to the spline sleeve rod 8 through a coupling. The spline sleeve rod 8 is sleeved in the spline sleeve 9. The spline sleeve 9 cooperates with the bearing seat 15 for positioning. A rubber pressure block 7 is arranged at the front end of the spline sleeve rod 8. The rubber pressure block 7 is facing the end face of the positioning rod 6. The entire clamping assembly is driven to move by the telescopic cylinder 2. The rubber pressure block 7 supports the workpiece to be laser marked on the positioning rod 6 to implement clamping. Driven by the rotating motor 10, the spline sleeve rod 8 drives the workpiece to rotate at a controllable speed to assist the laser laser equipment in marking the surface of the metal pipe.

[0022] A further implementation scheme is that the positioning rod 6 can be replaced by a positioning sleeve, which is inserted into the positioning sleeve to fit the metal rod to be laser marked, and the rubber pressure block 7 is opposite to the end face of the positioning sleeve. The telescopic cylinder 2 drives the entire clamping assembly to move, and the rubber pressure block 7 supports the workpiece to be laser marked on the positioning sleeve to implement clamping.

[0025] The working principle is: the servo motor transmits power to the rotating shaft, which in turn drives the turntable to rotate a specified angle, so as to select a suitable positioning rod or positioning sleeve to position the workpiece to be laser marked, and use the telescopic cylinder to pull the sliding frame to press the spline sleeve rod connected to the rotating motor against the workpiece. Driven by the rotating motor and limited by the freedom of the bearing seat, the positioned and clamped workpiece rotates accurately and precisely, and cooperates with the laser equipment to implement surface marking operations.
