The utility model discloses a clamping device for
metal steel
pipe processing, which comprises a steel
pipe clamping device, the two sides of the top of the steel
pipe clamping device are fixedly connected with support rings, the inner sides of the support rings are rotatably connected with
metal rods, and the surfaces of the
metal rods are fixedly connected with hold-down rings. A
servo motor is started, the
servo motor drives a second bevel wheel to rotate, the second bevel wheel drives a first bevel wheel to rotate, the first bevel wheel drives a screw to rotate, the screw drives a lifting plate to move upwards, the lifting plate drives a toothed plate to move upwards, and the toothed plate moves to drive a gear to rotate. The gear rotates to drive the metal rod to turn over, the metal rod turns over to drive the pressing ring to press the steel pipe, the steel pipe can be fully fixed, the steel pipe can be clamped and fixed, follow-up
machining and
cutting are facilitated, an existing manual clamping mode is replaced, and therefore the efficient and automatic clamping effect is achieved.
