Abstract
The invention relates to a symmetrical multi-cutter rod tube grooving machine which comprises two symmetrically-arranged cutter sets. A plurality of milling cutters are installed on the cutter sets, the cutter sets are driven by a frequency-conversion type alternating current asynchronous motor or an alternating current servo motor to rotate at a high speed, movable plates at the bottoms of the cutter sets can be driven by a stepping motor to enable the two cutter sets to conduct symmetrical feeding, and when the milling cutters on the cutter sets are in contact with rod tubes, the rod tubes can be cut; the rod tubes can be driven by a three-jaw chuck to perform larger-than 180-degree swing around the self axes, and circular grooves can be cut in the rod tubes. By means of the symmetrical multi-cutter rod tube grooving machine, full-automatic grooving is achieved, and repeated clamping or cutter replacing is not needed in the grooving process; the multiple symmetrical cutters work at the same time, the grooving efficiency is improved, and multiple V-shaped grooves can be machined on the rod tubes through one-time cutter feeding; the working continuity of the machine is good, the multiple milling cutters in the circumferential direction work at the same time, the abrasion speed of one single milling cutter is decreased, and the cutter replacing frequency is decreased.
