Description

Technical Field

[0001] The utility model relates to the technical field of blade processing, in particular to a blade drilling device for an electric fan. Background Art

[0002] Fan blades, also known as fan blades, are components of table or ceiling fans. They are driven by a motor to generate airflow. A fan typically consists of multiple blades and a rotor. Therefore, holes need to be drilled on the end of the fan blades closest to the rotor to facilitate installation. Turning is a common method for drilling these holes.

The device comprises a frame, a cooling box, a workbench, a work box, and a fixture box fixed to the frame. The frame includes a drilling device positioned above the workbench, a liquid outlet pipe connected to the cooling box, and a fixed block fixed to the drilling device. The work box and fixture box are located below and above the workbench, respectively. A collection port is provided on the top surface of the work box. A first piston plate is vertically slidably connected within the work box, with a first connecting rod fixedly connected between the first piston plate and the fixed block. A second piston plate is vertically slidably connected within the fixture box. A heating device is fixedly connected to the side wall of the fixture box. A pressure block is vertically slidably connected to the frame, with a second connecting rod fixedly connected between the pressure block and the second piston plate. A second one-way liquid outlet valve is provided on the side wall of the work box, connecting the second one-way liquid outlet valve to the cooling box and a cooling pipe. This solution, used for drilling holes in fan blades, allows for timely replenishment of coolant.
