The utility model relates to an external diameter copying tool holder of an external chuck grooving machine pipeline, which comprises a main tool holder, a secondary tool holder and a rotary ring of the grooving machine. The main tool holder comprises a feed star wheel, a screw rod, a screw mother tool holder slide block, a copying tracking wheel, a sliding seat, an upper slide block and a multi-position chuck seat. A sliding seat is installed on the inner half of the two convex blocks of the auxiliary tool holder through bolts, and two convex blocks on the auxiliary tool holder are outside the two convex blocks. A U-shaped block is fixed and welded on the half side, and a screw rod is installed inside the U-shaped block through a bolt. The main tool holder and the auxiliary tool holder are made of high-performance aluminum alloy material. The utility model adopts a completely new design scheme and adopts side spring structure to minimize the radial dimension requirement of the pipeline on the premise of ensuring the processing requirement of the equipment. The device has the same installation interface as the conventional tool holder of groove machine, which improves the interchangeability. The main and auxiliary tool holders are made of high performance aluminum alloy material, realizing lightweight, and the spring pressure can be online. Tune.
