Technical Field

[0001] This utility model relates to the technical field of nut tapping equipment, specifically an automatic nut tapping device. Background Technology

[0002] A tapping machine is a machine tool that uses taps to machine internal threads. It is the most widely used type of internal thread machining machine tool. According to national machinery industry standards, tapping machines are classified into: benchtop tapping machines, semi-automatic benchtop tapping machines, vertical tapping machines, and horizontal tapping machines. For some reason, an important and widely used category is not included: articulated arm tapping machines (hydraulic tapping machines, electric tapping machines, pneumatic tapping machines). During the production of stainless steel nuts, internal threads need to be machined using a tapping machine to meet actual production needs. When tapping nuts, the tapping machine produces flying metal chips, which can easily cause adverse effects on the surrounding environment and workers. Utility Model Content
