[0021] like Figure 1-4As shown, this utility model provides a technical solution: a rotary clamping mechanism for cutting steel structure beams, including an external toothed turntable 1 and two sets of clamping components 2. The two sets of clamping components 2 are distributed one in front of the other along the same horizontal axis. The horizontal axis of the external toothed turntable 1 is coaxial with the horizontal axis of the clamping components 2, and the external toothed turntable 1 is fixed on one of the clamping components 2. The center of the clamping components 2 is provided with a feeding area for horizontal feeding of the steel structure beam 3 perpendicular to the beam.
[0022] The clamping assembly 2 includes a fixed seat 21, a bearing 22, a flange 23, and positioning adjustment wheels 24 arranged sequentially along a horizontal axis. The fixed seat 21 is fixedly installed and can be fixed to the operating table or a fixed bracket. The flange 23 and the external gear turntable 1 are rotatably mounted on the fixed seat 21 via the bearing 22. The inner ring of the bearing 22 is fixedly fitted onto the protrusion 211 of the fixed seat 21. The flange 23 is fixed onto the outer ring of the bearing 22 by fixing bolts 231. The external gear turntable 1 is fixedly fitted onto the outer ring of the bearing 22. The positioning adjustment wheels 24 are arranged in a ring around the material feeding area and fixed on the flange 23. At least four sets of positioning adjustment wheels 24 are provided, and the four sets of positioning adjustment wheels 24 are distributed along the four directions of the steel structure beam 3: up, down, left, and right.
[0023] The positioning and adjusting wheel 24 includes a clamping wheel 241, a threaded adjusting rod 242, a guide rod 243, and a mounting base 244. The mounting base 244 is fixed to the flange 23 by fixing bolts 2441.
