In general, circular products or workpieces are shapes that are widely encountered in daily life, and countless processes and operations such as sheet metal, cutting, machining, etc. With the development of technology, the digital system is combined with various analog mechanical devices to automatically divide the hole at regular intervals and the precision processing of large holes is developing day by day.

However, it is very inconvenient and cumbersome to measure and process the finished workpiece again.

The problem with processing circles is

First, measure the diameter of the machining circle with a precision measuring instrument, find the center line by dividing the circle with a compass or ruler into halves or thirds, or find the maximum point on the horizontal axis and the maximum point on the vertical axis of the circle using a dial gauge. It takes a lot of effort and time to find the central coordinates.

Second, the most frequently used function of the ruler is to draw gold after cutting using the ruler's scale on a two-dimensional plane. It takes a lot of time to divide a circle with such a ruler, draw a center line, and measure the angle. The center line of the circle must be found first, and the circle is then divided based on the center line to make a mark with a punch and then the circle is machined using a drill. Various commercial techniques for drawing the center line of a circle are used, but in the following prior art (201510488854.3 (2015.08.12), CHINA SECOND METALLURGY GROUP CO., LTD.), these commercial devices are optimal for drawing the center line of the outer diameter of a circle [Fig. 4 ], there is a disadvantage that a center line cannot be drawn using the inner diameter of a circle. In addition, the right and left V-wings have the disadvantage that it is difficult to apply to various sizes and not easy to manufacture.

Third, the work of creating the center origin of the inner and outer diameters of the circle is an essential task in the production site. For a small circle, attach a dial gauge or an indicator to the spindle, contact the measuring needle to the inner and outer diameter of the circle, and rotate 360 degrees to find the center origin of the circle. However, in order to measure a material with a large circle, the arm of the dial gauge must be made long and large. That is, the origin of a small circle can be measured by investing a lot of time and various methods. However, if the circle becomes larger, it is impossible to create a central origin due to the distance problem of the measuring device.

In order to solve the problems presented above, in Figure [1], in the X, Y and Z axis perpendicular to the plane, the length direction of the ruler X, the width Y of the ruler, the bottom surface of the ruler whose thickness is Z, the XY plane, or the YZ plane In, the protruding member in and out of the circle is formed symmetrically left and right with the center line on the X axis, which is the length direction of the ruler, and an imaginary line 32 connecting the central point 33a and the central point 33b of the protruding member, and an imaginary line 32 The center line (3) that bisects symmetrically is composed of a line perpendicular to the imaginary line (32), and is composed of a straight line (3) passing through the center point (7) of the workpiece, characterized in that it has a center plane (126) A device for generating inner and outer diameter center lines and center planes of a circle is presented.

We present a method of forming the central cross section of the frame that is orthogonal to two contact points so that it can also function as a T-shape.

In addition, the device for generating the inner and outer diameter center line and center plane of the circle may be characterized in that the first frame 13 and the second frame 12 are separated. In the Z axis perpendicular to the plane XY, the length direction X of the ruler, the width Y of the ruler, and the thickness of the ruler are the X axis of the ruler's longitudinal direction. is formed symmetrically to form a first frame 13, and a surface and a groove (1) are configured based on the center line (3) of the first frame so that the second frame 12 in the longitudinal direction is easy to assemble, The second frame 12 is coupled to and fixed to the groove (1) configured based on the center plane. One or two protruding member contacts are formed on the edge of a plate-shaped member with a rectangular plane and a certain thickness, and a vertical plane that bisects the contact is completed to compose the device,

A method of constructing a device that can easily make a central plane by configuring a rectangular plate having a vertical surface in a T-shape or by installing a plurality of frames having contact points with protruding members having the function of a right angle is presented.

In the configuration of the inner/outer diameter center origin generating device of the circle,

1) obtaining two holes (8h, 9h) at equal intervals on the edge of a rectangular plate of constant thickness and a vertical centerline (3) dividing them into two;

2) machining two holes and a center line;

3) Combining the two holes and the center line perpendicular to the center line of one side of the long and narrow plate 12 at the two holes

4) A step in which a pin contacting the inner and outer diameter of the circle is installed or cut in the two holes;

5) assembling the reference surface 126 and the reference pins 8 and 9 of the combined ruler.

How to create the center origin of the inner and outer diameters of a circle

1) The step of obtaining the horizontality in the X direction by touching the two contact pins to the inner or outer diameter of the circle

2) The step of matching the origin plane and the position of the machine

3) The step of saving the position of Y as the origin

4) Step of obtaining the horizontality in the Y direction by touching the two contact pins to the inner or outer diameter of the circle

5) Step to match the origin plane and the position of the machine

6) Step of saving the position of X as the origin

7) Step of setting the saved X and Y positions as the origin

A method for setting the origin of X and Y is presented.

Other laser points, magnetic members, frame locks, multi-frames, levels, etc. are combined to provide a device that creates a center plane and a center line.

In a frame having a frame plane XY, a longitudinal direction X of the frame, a frame width Y, and a frame thickness Z, two protruding members having respective center points 33a and 33b on the Y-axis line of the bottom surface of the plane XY are spaced at regular intervals (32a). ), an imaginary line 32 connecting the center points of the member 33a and the member 33b is formed, and frames 53 and 13 based on the bisector center line 3 orthogonal to the imaginary line 32 The reference cross-section 126 formed in the second frame is configured with a fixing member such as a hinge, a reference pin, and a reference surface of the concave-convex groove and protrusion formed between the pin and the pin so that the reference surface is formed at the same time as the coupling to the first frame. It is provided and configured to facilitate assembly. In addition, it is configured by being coupled to the rotation shaft 25 formed in the frame based on the bisecting center line 3 as a separate type, and position data such as angle and length are stored in the basic frame 13 based on the center line. It is formed in the second frame 12 coupled to the axis and is characterized by a device for generating the inner and outer diameter, center origin and center plane of the circle, which may be configured to be attached to a digital display device that calculates and controls position values.

With the existing technology, it was impossible to create a centerline in the inner diameter, but using this technology, the centerline and center plane of a circle can be obtained under any conditions such as inner diameter versus inner diameter, outer diameter versus inner diameter, and outer diameter versus outer diameter, and the angle associated with the hole can be calculated. can be measured

In addition, the center plane and the center line that are in contact while processing a circle are very important factors as a reference plane for cutting or measuring a circle.

By using the device of this technology, anyone can simply obtain the center line and the center plane even without specialized skills, and it is possible to shorten the machining time, increase work efficiency, and improve productivity.
