In the production of electronic products such as mobile phones, tablet computers, personal digital assistants, MP3 and MP4, sheet-shaped small sheet metal workpieces are usually used as mounting plates, frames, etc., and these workpieces are generally used as the main frame for installation. During the assembly process of the workpiece, the nut is first installed in the mounting hole of the workpiece. In the later assembly, other components can be directly fixed on the workpiece with screws, which is convenient for later assembly; Nut holes are opened, but because the size of these workpieces is relatively small, especially when nuts need to be opened on the inner surface of the workpiece, the frame of the workpiece will limit the range of movement of the drilling equipment, so the general drilling machine is used to drill on the inner surface. The requirements for drilling are very high, and it is difficult for workers to operate, and the quality of drilling cannot be guaranteed if they are not careful, which will increase the defective rate of products and affect the processing efficiency.
