Abstract
A tapping apparatus adapted for tapping a workpiece includes a lower die unit to drive the workpiece to move along a conveying direction, and an upper die unit disposed above and movable upwardly and downwardly relative to the lower die unit. A tapping mechanism is disposed between the lower and upper die units to be driven by the upper die unit for tapping the workpiece so that the workpiece is formed with a tapped hole. A thread checking mechanism is disposed between the lower and upper die units and is spaced apart from the tapping mechanism along the conveying direction. The thread checking mechanism is driven by the upper die unit for checking the tapped hole of the workpiece.
