The present invention relates to an automatic measuring apparatus for an inner diameter using an air micrometer with a built-in CNC lathe, and more particularly, to a CNC lathe for automatically measuring the inner diameter of a machining area, And an inner diameter automatic measuring device using an air micrometer with a built-in CNC lathe capable of efficiently measuring the inner diameter of a measured object.

In general, manufacturing processes for various types of machining that can machine parts of machine elements having various structures and shapes such as automobiles or mechanical devices are used to measure the machining dimensions of the outer diameter or inner diameter for each product for the purpose of product quality control And the like are installed and used.

Here, a computerized numerical control (CNC) lathe, which is one of the main facilities for machining parts, is used to program the data of machining shape, machining conditions and machining operation by a computer, And then drives the workpiece to be machined.

As a measuring device for measuring the dimensions of a workpiece machined from such a CNC lathe, there is a measuring device which is configured to discharge compressed air of a certain pressure and accurately measure a minute dimension of the measured object by the flow rate and pressure change. Micrometers (air micrometers) are widely used.

As a conventional technique disclosed in relation to an air micrometer in the above-described measuring apparatus, Korean Patent Registration No. 615517 (2006.08.17.) Discloses a filter for removing impurities from air forced in from the outside, A variable throttle for adjusting a discharge amount of the compressed air compressed by the voltage regulator according to a control signal, and a control unit for controlling the operation mode of the user And a central processing unit for controlling the voltage regulator and the variable diaphragm according to the setting of the mode setting unit and the mode setting unit. Accordingly, there is known an air micrometer capable of efficiently measuring the dimension by connecting the measuring head.

However, in the case of the conventional air micrometer described above, it is separated from the CNC lathe, which is a processing facility, and is installed only as a separate measuring device. Therefore, after the CNC lathe is processed and the object to be measured is separated from the chuck unit of the CNC lathe, Since the measurement can be performed using an air micrometer, it is very troublesome for the operator to perform the measurement work due to the manual operation, and the operation time is delayed and the productivity is deteriorated.

In addition, when the measured object is measured from the air micrometer and the measured value is small, it is necessary to fix the object to the chuck unit of the CNC lathe when the rework is required, There is a problem that precise machining of the product is difficult because a slight error occurs in the machining centering.
