AI Technical Summary
Existing hole-reaming devices have difficulty in accurately raising and lowering the drill bit, resulting in inaccurate hole-reaming depth, difficulty in moving to the appropriate position, affecting hole-reaming effect and accuracy, and difficulty in clamping and fixing the valve body, leading to displacement and instability.
The system employs a lifting and moving mechanism and a clamping and fixing mechanism. The precise movement of the drill bit and the stable clamping of the valve body are controlled by a motor and an electric push rod. The smooth lifting and lowering of the drill bit is achieved by using a ball screw and slide rail structure, and the electric push rod clamping plate ensures the fixation of the valve body.
It achieves precise movement and stable clamping of the drill bit, ensuring the accuracy and flexibility of hole reaming, avoiding problems such as drill bit deviation and valve body deviation, and improving the accuracy and stability of the hole reaming device.
