The electric tapping machine tapping chuck safety overload tapping chuck is connected by the connecting sleeve member, the transition sleeve member and the scale sleeve member, and the steel ball member is positioned by two bodies. The electric tapping machine tapping chuck safety overload tapping chuck is connected by the connecting sleeve member, the transition sleeve member and the scale sleeve member, and the steel ball member is positioned by two bodies.
The working principle of the electric tapping machine tapping chuck: with 2 positioning pins and 4 screws through the coupling sleeve, the CNC machine tool spindle and the tapping chuck are connected together, so that the connection precision between the tapping chuck and the machine tool is first ensured. Pulling the outer sleeve member to determine the torque required for tapping, the butterfly spring will be pressed by the force, positioned by the steel ball, and the threaded sleeve is connected to tap.
Tapping chucks use the butterfly spring to generate pressure work, H44H check valve, 100x remote control float valve vintage chuck is driven by clutch, the new chuck is linked by steel ball. The clutch fit is tooth-shaped, the positioning is not fine, and it is easy to wear. http://Because only a group of butterfly springs are not evenly loaded, it will not reflect the true force of the butterfly spring and affect the use. The new type of chuck, steel ball is not easy to wear, accurate positioning; each group of 36, a total of 6 sets of contour butterfly springs to ensure uniform force; the scale sleeve is engraved with 200N•m ~ 1400N•m mark, according to the tap The magnitude of the torsion torque is determined by the value of the torsion and locked by the top wire member 39 to prevent loosening.
