BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device for automatically and easily measuring the dimensions of a cutting tool.

[0002]

2. Description of the Related Art Conventionally, for measuring the tool length and tool diameter of a cutting tool as shown in the explanatory view of FIG. 2, a dial gauge is applied to the tool tip to detect the tip of the cutting tool, or cutting is performed using a microscope. The tool tip was enlarged and measured. Further, the blade tip R at the tip of the tool was visually measured for a gap between the R gauge and the blade tip R. Therefore, in such a measurement method, in order to measure the tool length and the tool diameter, the tip portion of the tool cutting edge is measured by fine adjustment by hand, and a skilled person pays close attention to measurement accuracy and damage to the cutting tool. I had to pay and work.

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and provides an automatic cutting tool measuring device capable of automatically and easily and accurately measuring the dimensions of a cutting tool. The purpose is to

[0004]

To this end, the present invention provides a diameter measuring machine capable of measuring the diameter of a cutting tool in a non-contact manner, a motor for rotating a block holding the cutting tool, and the diameter measuring machine described above. With a motor that moves vertically with respect to the holding block, the tool length of the cutting tool, the tool diameter, the tool R
Is characterized by automatically measuring.

[0005]

In the automatic cutting tool measuring device of the present invention, the tool length (maximum length) of the cutting tool can be detected by detecting the tip of the cutting tool while the block is being rotated. Further, the tool diameter (maximum diameter) can be detected by detecting the change in the diameter of the cutting tool tip. Furthermore, the tool length, tool diameter,
From the position of any one point on the cutting edge R, the circle equation (x ² + y
It is possible to obtain the cutting edge R by using ² = r ² ).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic measuring device for a cutting tool according to the present invention will be described with reference to a perspective view of FIG. 1. The automatic measuring device according to the present invention comprises: a tool pot 1 for holding a cutting tool 6; A laser diameter measuring machine 3 capable of measuring up to φ60 without contact, a motor 4 for moving the laser diameter measuring machine 3 up and down with respect to the tool pot 1, and a control computer 5. A cutting tool 6 to be measured is placed in the tool pot 1, and the tool pot 1 is rotated together with the cutting tool 6 during measurement. The laser diameter measuring machine 3 is used to detect the tip of the cutting tool 6 and the tool diameter. This laser diameter measuring machine 3
Is moved up and down by the motor 4. The control computer 5 centrally controls these devices.

Thus, in this device, the cutting tool 6
Since the measurement, recording, and printing are performed automatically only by setting the tool in the tool pot 1, even an unskilled person can easily perform the measurement with high accuracy, and an entry error at the time of transcription does not occur. Further, since all measurements are performed using the laser diameter measuring machine 3 in a non-contact manner, the cutting tool 6 is not damaged and the measurement can be easily automated. Further, since the cutting tool 6 is measured while being rotated, the maximum dimension of the cutting tool 6 can be detected.

[0008]

In summary, according to the present invention, the diameter measuring machine capable of measuring the diameter of the cutting tool in a non-contact manner, the motor for rotating the block holding the cutting tool, and the diameter measuring machine in the holding block. With a motor that moves vertically with respect to it, by automatically measuring the tool length, tool diameter, and tool R of the cutting tool, it is possible to automatically and easily measure the dimensions of the cutting tool. I get the device,
The present invention is extremely useful in industry.
