Therefore, flange tapping technology is an important link in the flange manufacturing process. The tapping quality directly affects the flange's connection strength and sealing effect. During the flange tapping process, it is crucial to ensure the stable clamping of the flange, which directly affects the accuracy and quality of the tapping. Traditional clamping methods often rely on manual positioning, and the positioning accuracy is greatly affected by the operator's skills and experience. It is easy to cause deviations between the flange center and the tapping tool center, affecting the verticality and concentricity of the tapping. In addition, traditional clamping methods may not provide sufficient stability, causing the flange to shake or rotate, affecting the tapping quality and efficiency. Utility Model Content

The outer wall of the adjusting screw 4 is threadedly connected with an adjusting block 6. Through the cooperation between the adjusting screw 4 and the adjusting block 6, the adjusting screw 4 rotates through the adjusting block 6 and the limit slider 7 to drive the four fixing blocks 9 to approach each other. The four fixing blocks 9 approach each other to clamp the flange, which can not only play a centering role and avoid the flange from being offset, but also ensure the stability of the flange when clamping. The upper part of the adjusting block 6 is fixedly connected with the limit slider 7. Four sliding grooves 8 are provided above the fixed platform 2. The limit slider 7 slides in the sliding groove 8. Through the cooperation between the limit slider 7 and the sliding groove 8, the limit slider 7 follows the adjusting block 6 in the sliding groove 8 to move along the inner wall of the fixed platform 2. In this way, the limit slider 7 is more stable during the movement.

[0019] A fixed block 9 is fixedly connected to the top of the limit slider 7, and a fixed head 10 is fixedly connected to the end of the fixed block 9. There are four fixed blocks 9, and the fixed heads 10 on the four fixed blocks 9 are relatively positioned. An output motor 11 is provided below the fixed platform 2, and the output end of the output motor 11 passes through the end of one side of the fixed platform 2 and is fixedly connected to a driving gear 12.
