いた。PRIOR TECHNOLOGY Many tool identification devices have already been published and used, but the one in which the identification part is provided on the outer periphery of the holder, for example, Utility Model Application Publication No. 109978/1983, has a large amount of unbalance and is difficult to use when the tool rotates at high speed. Sometimes it has a negative effect. In addition, in other devices, the identification device is often complicated, and the construction cost increases. Furthermore, if the identification code portion is exposed, contamination with cutting fluid, chips, dust, etc. causes unstable detection, and furthermore, there are drawbacks of varying degrees, such as damage during replacement.

られている。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. The tool or tool holder 1 has a groove 3 in the base 2 which is gripped by a gripper of a tool changing arm (not shown), and the end face of the pull stud 5 at the end of the taper shank 4 has a plurality of grooves equally divided on the same circumference from the axis. Holes 7 into which pins 6 serving as objects to be detected can be inserted so as to protrude are drilled at six locations at fixed angular positions with respect to the keyway 10 in which the tool holder is positioned. If the pin 6 is installed in the hole, a binary number of 1 will be displayed, and if it is not, a binary number of 0 will be displayed, so that 2 6 = 64 types can be identified by the 6 holes, and the tool 64
It can be used until now. A larger number of tools can be identified by providing 8 holes or 6+1 holes by providing one hole in the center. Six sensors 8 that detect the presence or absence of this pin 6 and output on/off signals, that is, 1, 0 signals, are embedded in the mounting base 9 at positions corresponding to the six equal parts of the hole 7 of the pull stud 5. .
When the tool holder stored in the bottomless tool pot of the tool storage magazine (not shown) is indexed and moved, the pull stud 5 and the sensor sensing section face each other to maintain a constant position relative to the tool, making it possible to move synchronously for one pitch. A mounting base 9 is provided in the passage path of the tool holder.

貼付するようになてもよい。 Of course, the tools in the magazine must always be placed in constant relation to the pot, or indexed in a constant position when indexed to the sensor sensing position. In general, the keyway 10 in Figure 1 is 180 degrees opposite to the 2
Because it is individually machined, the operator may store it 180 degrees in the opposite direction when storing it in the magazine pot.
To avoid such mistakes, marks (eye marks) are usually placed so that the relative positions during storage can be seen, but in order to automatically detect If it is possible to detect the 180° opposite position by creating a hole, then it is easy to electrically shift the phase by 180° and read the correct tool number. Each time the tool in the magazine is fed one pitch, it makes a short stop, and the sensor detects this moment. Alternatively, the sensor mounting base 9 is synchronously fed within the range of one indexing pitch, during which the hole 7 of the tool and the sensor 8 are maintained in a constant relationship, the positions of the protrusions and recesses are detected, and the magazine continues until the predetermined tool is indexed. You can also send it. The sensor 8 is designed to detect only the pin 6, and the signal is sent to the NC, which identifies the tool number based on which hole and which hole the pin 6 is placed in. If pins are planted in holes 7 1 and 7 3 of hole numbers 7 1 , 7 2 , 7 3 , 7 4 , 7 5 , and 7 6 of hole 7, the tool number will be No. 5 in the EIA code. represents. In this example, the pin is inserted into the hole, but it is also possible to make a hole only in that part.Of course, it is not necessary to make a hole in the position where the pin is not inserted, but the tool number Considering the degree of freedom when changing the position, it is preferable that holes be provided at all positions. Also, instead of installing pins, a plate drawn with a press or the like may be attached.

で安価な構成となる特徴を有するものである。Effects As detailed above, the present invention includes a first code member for identifying the positional state of the keyway of the tool when the magazine is stored, and a type of the tool on the end face of the pull stud of the tool or the tool holder or on the plate member attached to the end face. A second code member that forms a code in combination for identification is provided, and the first and second code members are provided in the tool passage path of the magazine.
Since we have installed a sensor that detects the code corresponding to the code member, it is possible to automatically detect errors in the tool storage position and read the correct tool number, and the pin that causes imbalance is extremely close to the center of the tool. The amount of unbalance can be reduced, and even when the tool rotates at high speed, problems such as vibration caused by this are extremely small and can be ignored. In addition, since it is possible to encode a commercially available tool shank by simple processing, there is no need to manufacture a special tool holder, etc., and it can be realized at a low cost. In addition, there is no problem in replacing tools, and changes in tool numbers can be easily accommodated by replanting pin positions and replacing plates. In addition, the pull stud is always housed in the spindle during machining, so there is no risk of cutting fluid or chips adhering to it, and even while it is stored in the magazine, it is located on the back side of the pot to prevent dust and reduce instability in detection. can improve reliability. Furthermore, since the code member is located at the rear open end, it is possible to achieve a structure that facilitates continuous reading operations, and also has features that the reading device can be adapted to block builds and has an inexpensive structure.
