[0015] Firstly, this utility model involves placing the flange to be inspected around multiple support blocks. The support blocks are made of a soft, non-slip material with grooves on their surfaces. By activating a cylinder inside the clamping barrel, the cylinder pushes a moving plate via a telescopic column. The moving plate, through a first connecting column, moves multiple large connecting plates. The large connecting plates, through a second connecting column, move multiple first fixing blocks. The movement of the first fixing blocks causes the multiple support blocks to unfold outward. When the multiple support blocks unfold, the second fixing blocks and second connecting rods cause small connecting plates to rotate. The small connecting plates are connected to the connecting blocks on the outer surface of the clamping barrel via the first connecting rods. The multiple small connecting plates then support the support blocks, and the multiple support blocks provide support and fixation from inside the flange. Through this technical solution, the flange receives uniform support force during quality inspection, avoiding excessive local stress that could lead to deformation or damage, and preventing the flange from loosening during quality inspection. It can also adapt to flange forgings of different specifications and sizes.

[0016] Secondly, when the flange needs to be rotated, the electric actuator on one side of the fixed plate is activated, which pushes the moving block to move. The moving block is fixedly connected to the sliding plate, and the electric actuator pushes the sliding plate to move. The sliding plate is slidably fitted onto the outer surface of the fixed frame by a slider, and the slider and the fixed frame limit the movement. When the sliding plate moves, it drives the gear plate connected to the bottom. The gear plate moves, which drives the geared transmission gear to rotate. The rotation of the transmission gear drives the small rotating column to rotate. The rotation of the small rotating column drives the connected power belt pulley to rotate. The power belt pulley drives the transmission belt pulley to rotate via the belt. The rotation of the transmission belt pulley drives the clamping barrel to rotate via the large rotating column. The rotation of the clamping barrel drives the clamped flange to rotate. Through the above technical solution, the flange can rotate 360 ​​degrees, allowing quality inspectors to comprehensively inspect all parts of the flange and observe the flange from different angles, including the inner surface, outer surface, bolt holes, etc., to ensure that nothing is missed.
