The present invention relates to a numerical value measuring device on a three-dimensional object, comprising a mechanism that generates a command signal for recording the detected position value when the object is displaced by a certain amount in the Y and Z axis directions.

An example of the embodiment of the present invention will be described below with reference to the drawings.
and Z-axis direction movement mechanism 3, and X, Y of this mechanism 2 and 6
and X to detect the Z position.

Y and Z position detectors 4.5 and 6, a numerical control device 7 for displaying and recording the position detection values of each of the position detectors 4.5 and 6, and the stylus 1, for example, a clay model of an automobile. At the measurement point of the three-dimensional object 8 to be measured, X, Y and Z
It is comprised of a mechanism 9 that generates a command signal for recording the position detection value when the position is displaced by a certain amount in the axial direction.

The X, Y and Z-axis moving mechanisms 2 and 6 in the present invention have an X-axis moving shaft 10 having a command signal generating mechanism 9 having a stylus 1 fixed to the end thereof, and are mounted parallel to this moving shaft 10. A magnetic scale 11, a reading device 12 equipped with a non-contact switch (sensor) brought close to the magnetic scale 11, a sliding bracket 16 to which the reading device 12 is fixed, and a sliding bracket 16 arranged in the Y-axis direction. A main column shaft 14 for guided movement, a magnetic scale 15 mounted parallel to the main column shaft 14, and a non-contact switch (fixed to the sliding bracket 16) for reading the magnetic scale 15. The base of the main column shaft 14 has a substrate 17, and the substrate 17 has a guide shaft fixed to the fixed u 18 for moving in parallel on the surface plate 18. 19, a magnetic scale 20 mounted and fixed in parallel to the guide shaft 19, and a reading device 21 equipped with a non-contact switch (sensor) for reading the MiJ magnetic scale 20 fixed to the 1grj board 17. It has become.

Further, X, Y and two position detectors 6.4 and 5 are used, for example non-contact switch detectors such as sensors, and are mounted on the axes of the reading devices 12, 16 and 21, respectively.

The operation of the apparatus of the present invention in the above configuration will be explained below. First, the detection positions of the moving mechanisms 2 and 6 are manually aligned with the reference point of the three-dimensional object 8 to be measured, and this position is set to zero display as the reference point position using the zero point setting dial of the numerical display device 7.

Next, the sliding bracket 16 is manually moved in the Y-axis direction by a certain amount along the main column axis 14, and at that position, the moving axis 10 is manually moved in the X-axis direction to generate a command signal to the three-dimensional object to be measured 8. Apply the stylus 1 of mechanism 9. Movement mechanism 2 at this time
and 6, ie the X, Y position of the moving axis 10 and the two positions of the guide axis 19, are detected numerically by X, Y and Z position detectors 6.4 and 5.

At the same time, the stylus 1 that hit the three-dimensional object 8 is displaced in the X-axis direction at the measurement point, and when the amount of displacement reaches a certain amount, the command signal generated in the command signal generation mechanism 9 causes the
The position detection values detected by the Z position detectors 6.4 and 5 are once displayed and recorded on the numerical display device 7.

From the above, the numerical measurement device for three-dimensional objects of the present invention can accurately measure three-dimensional objects such as clay models of automobiles, quickly and easily, and is an outstanding product that can bring great industrial benefits. You can expect good results.
