[0002] Special drilling equipment is customized according to the characteristics of the impeller. Generally, the impeller is transported to the processing position, and then the special drilling mechanism performs drilling processing according to the preset program. During the processing, the processing quality is monitored in real time through the detection device to ensure that the accuracy and quality of the drilling meet the requirements.

[0003] At present, in the existing technology, during the drilling process, if the impeller cannot be clamped synchronously, the impeller may move or shake slightly, which will cause the position of the drill hole to deviate and affect the drilling accuracy. In addition, during the drilling process, the friction between the drill bit and the impeller material will generate a large amount of heat. If the heat cannot be dissipated in time, the local temperature of the impeller will increase. In view of this, we propose a drilling device for processing submersible pump impellers.

By pressing the handle, the cross block on the handle is engaged with the cross groove on the clamping column, and then the handle is turned to drive the rotation of the clamping column, driving the meshing of the gear and the rack. The extension of the rack plays its blocking role, and the rack prevents the fan from continuing to move in a specific direction, ensuring that the fan can accurately align with the area on the impeller that needs heat dissipation. By continuously adjusting the position of the fan, it can be ensured that all parts of the impeller can obtain sufficient heat dissipation and effectively control the temperature of the impeller.

[0018] (4) The drilling equipment for processing the impeller of the submersible pump is provided with a heat dissipation component. The wind direction of the fan passes through the fixed frame to blow the movable column, and the fan blades rotate continuously to reduce the local temperature. When the fan is working, the wind force generated can act on the hollow sliding block to slide to the right. The sliding block slides to the right under the action of the wind force, and then accelerates the sliding of the movable column through the auxiliary connecting pipe of the extrusion rod. The sliding of the movable column drives the fan blades to rotate, thereby generating a continuous airflow to dissipate heat for the drill bit and the impeller, which not only improves the heat dissipation efficiency, but also makes the operation of the rotating heat dissipation component more coordinated and efficient.
