Abstract

(57) [Abstract] [Purpose] In order to achieve more automation and unmanned operation, the present invention provides an ID chip memory and a center computer by providing a means for supplying a coolant. By collating the information, more reliable work can be performed, and since chips are sufficiently processed by the coolant, the purpose is to promote automation and unmanned work. According to the present invention, a recess is provided in the head of a pull stud attached to the upper part of an arbor, and an ID chip is installed.
A path for passing a plurality of coolants is provided around the recess.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to setting of a data carrier related to automation / electronicization when a cutting tool is used in MC or the like.

[0002]

[Prior Art]

 When cutting a workpiece with a rotary tool such as a drill, tap, end mill, etc. in MC, insert multiple chips into each cutting tool body and measure and record the offset amount with a presetter, as many tools are used together. Input the offset amount to MC, correct the origin, and start the work.

In addition, since a large number of cutting tools are used, these records are recorded in a center computer, centrally managed as tool information, a data carrier is installed in the cutting tool body, and a number is assigned to the tools for management. Has also been done. Further, an ID chip, a bar code, etc. are used for this data carrier. (As an example, Japanese Patent Laid-Open No. 3-154734)

A centralized management system using such a computer is used for this data carrier after actually starting the work after transmitting and checking the information about the tool by the communication between the center computer and the data carrier. In the case of a frying tool, the ID chip is currently installed in the upper part of the arbor or in the notch of the bottle grip.

[0005]

[Problems to be solved by the device]

 However, simplification such as chip disposal is essential for automation and unmanned operation. The chips are usually removed from around the tool by jetting air and blowing it away, or by using water-soluble or oil-based cutting oil to wash it away. These coolants are supplied through the arbor / tool holder in the vicinity of the cutting tip through the center through method, and from the side of the arbor through the tool in the vicinity of the cutting tip through through. There is a method of supplying and a method of supplying from a nozzle outside the arbor. On the assumption of automation, it is difficult to automatically adjust the positions of nozzles and the like, and the center-through method is inevitably advantageous especially when handling large workpieces.

Therefore, when the ID chip is attached to the upper part of the arbor, it is necessary to supply the coolant by the side-through method, and it is possible to install the ID chip in the cutout portion of the bottle grip or the like, but at the grip portion. Because it is tempered and has high hardness, it is harder to process than pull studs. Furthermore, since the arbor body is processed, handling and the like also pose a problem. The pull stud is a replacement part for the arbor and can be pre-processed, or can be easily mounted even when the ID chip is attached to the arbor or the like currently in use.

[0007]

[Means and Actions for Solving Problems]

 Therefore, in the present invention, a recess is provided in the head of the pull stud attached to the upper part of the arbor as shown in FIG. 1, and the ID chip is installed. As shown in FIGS. 2 and 3, a plurality of recesses are provided around the recess. The feature is that a passage for passing the coolant is provided, and the coolant can be used at the same time when the ID chip is attached, and the current cutting tool can be used. Further, in order to protect the ID chip, a cover or the like may be attached to the upper part of the ID chip to protect it from the coolant.

Next, the capacity of the ID chip as a data carrier has a capacity of 256 bytes even at the time of application, and is not limited to the range where the tool number is assigned and the presetter measurement result is used as a memory. The information stored in the ID chip memory can be checked with the information about the tool by communicating with the center computer, and the shape of the tool (material type-high speed steel, carbide, coating, cutting tool-model number, external Enter the diameter and number of flutes, and set the cutting specifications (cutting speed, feed rate, depth of cut (axial direction, radial direction), the presence or absence of coolant during cutting), etc. in memory, and the computer information and data. By collating with the carrier information, more reliable work can be performed.

[0009]

【Example】

 The operation procedure when using the system of the present invention is to set a cutting tip in a holder, measure an offset amount with a presetter, and store the measured value in a data carrier or a center computer. After that, when the work is actually set in the magazine and the work is started on the MC, the tool is identified from the information of the ID chip, the measured value of the presetter is collated with the information of the ID chip, and the offset amount of the center computer is calculated. Check the memory, and if they match, start cutting.

Therefore, if the information of the computer and the information of the data carrier do not match, the process cannot proceed to the next step, so that the check function for preventing malfunctions is further strengthened and the coolant can be supplied by the center through method. However, the chip disposal is fully performed, and the accuracy of automation and unmanned operation can be improved.

[0011]

[Effect of the device]

 The present invention is characterized in that a recess is provided in the head of the pull stud attached to the upper part of the arbor, the ID chip is installed, and a path for passing a plurality of coolants is provided around the recess. More reliable work can be performed by collating the stored contents of the data carrier of the ID chip with the information on the tool by communicating with the center computer. In addition, since chips are sufficiently processed by the coolant, it has many effects on automation and unmanned work.
