Abstract

The invention discloses a rotary shaft device of an integrated thin-wall pipe pneumatic clamping mechanism. The rotary shaft device is of a structure which is hollow inside, so as to realize pipe conveying and wet cutting operation. The rotary shaft device comprises a rotary shaft outer shell module, a tension rod module and a chuck module; the tension rod module comprises a tension rod, a pipe and a direct-driven motor, wherein the tension rod is formed by a hollow thin-wall seamless pipe; the inner diameter of the tension rod is more than the outer diameter of the pipe so as to contain the pipe to be processed; the tension rod is fixedly coupled on the rotor of the direct-driven motor; and the chuck module is used for assisting the tension rod module in clamping and loosening the pipe. A sensor is arranged in the tension rod, and the sensor identifies metal materials and non-metallic materials so that pipes are easily counted and automatic feeding is realized.

Description

technical field [0001] The invention relates to the technical field of laser micromachining of thin-walled pipes, in particular to a rotating shaft device integrating a gas clamping mechanism for thin-walled pipes. Background technique [0002] With the continuous development of laser micromachining technology, in order to pursue high-speed and high-precision processing effects, many key core components are used in the field of laser micromachining equipment. As an essential core component of CNC processing equipment, the precision rotating shaft is widely used in high-precision laser processing equipment. At present, the precision rotating shafts used in laser micromachining mostly rely on foreign imports. These imported precision rotating shafts are expensive, have a long lead time, have complex structures, and are inconvenient to repair after the components are damaged, and because they are all introduced as standard parts, it is difficult to flexibly change the design a...
