[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0021] Reference Figures 1-4, what is disclosed in the embodiments of the present utility model is: a clamping device for automatically clamping steel pipes, including a machine case 1, a clamping cylinder 3, a first synchronous pulley 13 and a second synchronous pulley 12. A sliding rod 2 is provided on the machine case 1. The clamping cylinder 3 is rotatably arranged at the end of the sliding rod 2. Two clamping jaws 4 for clamping steel pipes are provided on the clamping cylinder 3. A first channel 11 is opened on the sliding rod 2. The first synchronous pulley 13 and the second synchronous pulley 12 are rotatably arranged in the first channel 11. A synchronous belt 14 is wound between the first synchronous pulley 13 and the second synchronous pulley 12. The rotating shaft of the first synchronous pulley 13 is connected to the clamping cylinder 3 for driving the clamping cylinder 3 to rotate. A first servo motor 5 for driving the first synchronous pulley 13 to rotate is provided on the sliding rod 2. A sliding device for driving the sliding rod 2 to slide is provided between the other end of the sliding rod 2 and the machine case 1. A lifting column 9 for driving the sliding rod 2 to move up and down is provided on the machine case 1. The lifting column 9 slidably penetrates through the machine case 1. A lifting cylinder (not shown in the figure) is provided in the machine case 1. The extending rod of the lifting cylinder is connected to the lifting column 9. A rotating servo motor (not shown in the figure) for driving the sliding rod 2 to rotate is arranged in the lifting column 9.

[0022] Specifically, the sliding device includes a connecting rod 6. The connecting rod 6 is arranged on the lifting column 9. The rotating servo motor is connected to the connecting rod 6 for driving the connecting rod 6 to rotate. A T-shaped block 7 is slidably arranged on the connecting rod 6. The sliding rod 2 is arranged on the T-shaped block 7. A sliding groove is opened on the connecting rod 6. The T-shaped block 7 is slidably arranged in the sliding groove.

A second servo motor 8 for driving the screw rod to rotate is provided on the connecting rod 6.

[0023] Among them, when clamping a steel pipe, the second servo motor 8 rotates, driving the screw rod to rotate. The screw rod drives the T-shaped block 7 to slide, thereby driving the sliding rod 2 to slide, and then the sliding rod 2 extends to the position where the steel pipe is placed. Then the lifting cylinder drives the lifting column 9 to descend. Then the clamping cylinder 3 works, driving the clamping jaws 4 to clamp the steel pipe. Then the lifting column 9 returns to its original position. The rotating servo motor works, driving the sliding rod 2 to rotate to the punching press. Then the lifting column 9 descends again.
