The inner clamping chuck device 70 includes an inner clamping chuck 71 for plugging and clamping the inner wall of the steel pipe port and a rotating drive mechanism for driving the steel pipe to rotate axially at any angle. In this embodiment, the rotating drive mechanism uses a driving motor and a reduction gear transmission group to achieve a 360° rotation of the inner clamping chuck to facilitate comprehensive rust removal.

[0037] Preferably, the present embodiment provides a steel pipe rust removal machine, wherein the rust removal machine head 20 is provided with a laser head for rust removal operations, and the high energy density and precise controllability of the laser are utilized to achieve rapid and efficient rust removal on the surface of the steel pipe.

[0047] Embodiment 3: Different from Embodiments 1 and 2, in this embodiment, a visual device 80 is also provided on the rust removal head 20 of a steel pipe rust removal machine, which is used to photograph the steel pipe on the clamping station, detect whether there is rust and other attachments on the surface of the steel pipe, and identify the rust state of the steel pipe surface, whether it is pure rust or a mixture of rust and surface attachments such as paint and concrete. When it is determined to be pure rust, the processing unit of the visual device guides the call of the laser head on the rust removal head 20 during processing to achieve the rust removal function; if the surface of the steel pipe is a mixture of rust and surface attachments such as paint and concrete, the grinding mechanism 60 is first called to grind the attachments during processing. After the grinding is completed, the laser head on the rust removal head 20 is called to remove the rust.

[0048] After the cleaning operation is completed, the visual device must also detect whether there is rust and other attachments on the surface of the steel pipe. If it is not cleaned thoroughly, the cleaning operation will continue until the cleaning effect is achieved.
