Cutting and positioning device of corrugation tube cutter

The utility model discloses a cutting and positioning device of a corrugation tube cutter, which is provided with a gear wheel; the circumference of the gear wheel is provided with an object to be inducted, and the distance between the circumference and the object to be inducted is identical with the waveform at the external surface of a corrugated tube. When cutting the tube, the gear wheel is sleeved on the corrugated tube and rotates following the corrugated tube; an inductor arranged at one side of the gear wheel is inducted to the object to be inducted and sends an induction signal to a coder; and the length of the corrugated tube is counted inside the coder according to the induction signal, and when the length reaches a set value, the inductor inducts the object to be inducted at the circumference of the gear wheel, and a blade is identical with the wave hollow of the corrugated tube, then the cutting device can cut, thus ensuring that the cutting blade is capable of cutting the valley bottom of a medium wave. The cutting and positioning device has simple proofreading means and high precision; the cutting mouth of the corrugated tube is neat and stable, the labor intensity is low and the work efficiency is high, and the cutting and positioning device of the corrugation tube cutter is suitable for the manufacture industry in large scale.
