Embodiment

[0025] A blade drilling device for an electric fan, such as figure 1 As shown, including the frame, the cooling box 1, the workbench 10 and the workbox 11 are fixed sequentially on the frame from top to bottom. The ratio of the cross-sectional area of ​​the upper surface of the workbox 11 to the workbench 10 is 5:3. The edge profile of the upper surface of the table 10 is wedge-shaped, and the top of the workbench 10 is provided with a drilling device fixed on the frame. The workbench is provided with a through hole positioned directly below the drilling device. Drill bit 6 and threaded rod 7, cylinder 27, motor 5, threaded rod 7 and drill bit 6 are arranged on the frame successively from top to bottom. The bottom of the cooling box 1 is connected with a liquid outlet pipe 4 with the nozzle facing the drill bit 6. The liquid outlet pipe 4 is coaxially connected with a rotary valve 2, and the rotary valve 2 is coaxially connected with a ring gear 3. The top of the rotary valve ...

Description

technical field [0001] The invention relates to the field of turning processing, in particular to a blade drilling device for an electric fan. Background technique [0002] The fan blade, namely the fan blade, is a component of a desk fan or a ceiling fan. The motor drives the fan blade to rotate, and the rotation of the fan blade can generate airflow. [0003] During use, a fan is generally used in combination with a plurality of fan blades and a rotor, so holes need to be drilled at the end of the fan blades close to the rotor to facilitate the installation of the fan blades on the rotor. The commonly used punching method is turning, specifically: fix the punched end of the fan blade on the workbench, and then punch the fan blade with a drilling device. In order to avoid damage to the drill bit due to overheating of the drill bit, coolant is usually sprayed on the drill bit to cool down. [0004] In order to prevent the waste of coolant, a coolant collection device is ge...
