Description

Automatic tapping system {automatic tapping system}

The present invention relates to an automatic tapping system, and more specifically, the parts aligned and transported through the feeding unit are transferred in opposite directions to each other and are pressed in both directions to the clamp groove of the clamp module, and are concentric with the tab by an inclined movement with the clamp groove. Because it is positioned accurately, the quality of tapping is improved. In particular, automatic tapping can significantly shorten the cycle time for tapping due to the continuous feeding method in which parts are put into one side of the clamp module, tapped, and then discharged to the other side. It's about the system.

Typically, a tapping machine that manufactures nuts by forming a nut groove in the base material is configured to first drill a hole at the tap pip position of the base material and then manufacture the nut by inserting a tap into the drilled hole.

Most of these tapping processes rely on manual work or use dedicated tapping machines. Manual work involves tapping by manually rotating the tap, so machining precision is reduced, work speed is slow, and expensive tab damage and breakage are frequent depending on the operator's skill level. This happens, and in dedicated tapping machines, loading/unloading of the base material is performed manually, so there is a significant difference in productivity depending on the operator's skill level.
