[0033] The working principle of this utility model: After the drive motor 5 is powered on, it converts electrical energy into mechanical energy, which is transmitted precisely and stably through the synchronous pulley set to drive the drill bit 27 to rotate.

As the equally spaced drive motor 5 drives the fixed base 11 to rotate, the fixing block 23 on the fixed base 11 precisely rotates to the processing position corresponding to the drill bit 27. At the same time, the electromagnetic sensor 12 senses the position of the fixing block 23 and triggers the extension rod 9 of the clamping cylinder 7 to extend and press the side of the workpiece 10 to ensure that the workpiece 10 does not move or shake during processing, ensuring processing accuracy and preventing damage to the workpiece 10. After the moving cylinder 14 drives the drill bit 27 to process the workpiece 10, the fixed base 11 rotates to move the processed workpiece 10 out of the processing position. The worker removes the processed workpiece 10 and then installs a new processed workpiece 10. This process is repeated continuously.
[0034] This utility model's drilling machine automatically drills holes in just 4 seconds per hole and can process continuously, significantly increasing output per unit time, improving production efficiency, facilitating large-scale production, and meeting the demands of large market orders. Workers only need to handle loading and unloading, reducing direct manual involvement in the drilling process, lowering labor intensity, reducing manpower, saving labor costs, and improving enterprise economic efficiency. Precise drilling reduces scrap rates, minimizes raw material waste, and saves production costs. During automatic drilling, the equipment parameters are accurately set and the operating status is stable, ensuring consistent drilling accuracy for each workpiece and improving product quality stability. It can be adapted to different specifications of drill bits and rotary table components to meet the drilling needs of various materials and different hole diameters. This utility model is highly efficient, can operate continuously, has precise positioning, reduces workpiece processing errors, reduces labor costs, saves consumables, and has replaceable drill bits and rotary table components, making it more widely applicable.
