Tapping machine for circuit board production and processing

The utility model discloses a tapping machine for producing and processing a circuit board, which comprises a workbench, the top of the workbench is fixedly connected with an L-shaped frame and a device frame I, the L-shaped frame is provided with an auxiliary assembly, the L-shaped frame is fixedly connected with a hydraulic telescopic rod, and the telescopic end of the hydraulic telescopic rod is fixedly connected with a device frame II. The two bolts are taken down manually, the two T-shaped rods are pulled to be separated from the two first U-shaped plates and the two second U-shaped plates respectively, then the first connecting plate and the second connecting plate are pulled to be separated from the two mounting grooves, and then the corresponding upper mold and lower mold are inserted into the two mounting grooves again. And after the two T-shaped rods are reset, the bolts are inserted again to limit the T-shaped plates, so that the replacement of the upper die and the lower die can be completed, the
