Abstract

PURPOSE:To make it possible to cool a tip by means of cool air by boring a hole for introducing cool air through the inside of a tool with one end of the hole opening to a tip attachment surface and the other end attached with an air cooler device which is freely detachable. CONSTITUTION:A throwaway tip 3 is attached to the front end of a shank 2 while a clamp mechanism for restraining the tip 3 to an attachment surface is incorporated at the tip side end portion of the shank 2. A hole 8 for introducing cool air is bored through the inside of the shank 2 with one end of the hole opening toward the attachment surface 4 while the other end opening to the rear end of the shank. An air cooler device 11 is connected via a nipple 10 to an opening 9. With the above arrangement, cool air supplied from the air cooler device 11 flows through the hole 8, goes out through a gap between the attachment surface 4 and the tip 3, and cools almost entire surface of the tip 3.

の構造に関するものである。[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a tool holder, and more specifically, to a structure of a tool holder that can cool chips without using cutting oil. It is related to.

。(Prior art and problems to be solved) A cutting tool, which is a cutting tool used for cutting with a lathe, planing machine, etc., is equipped with a cutting edge (chip) made of a cutting material such as high-speed steel at the tip. It is used by holding it in a holder.

えるように工夫されている。By the way, cutting oil is used to cut the workpiece at high speed as the tip becomes very hot, but it wears out rapidly and must be replaced frequently.For this reason, conventional types such as lever lock type and pin lock type are used. Various types of clamping mechanisms are built into the shank, and are designed to allow tip replacement in a short time.

しいとは言えない。However, since the replacement work of the so-called indexable tip of the above-mentioned type uses cutting oil, it is difficult to carry out the work smoothly because cutting oil has to be attached to the parts. Furthermore, since an oil supply device for supplying cutting oil and an accompanying oil recovery device must be attached to the working mechanism, the mechanism becomes complicated, which is not desirable in terms of workability and economy.

目的とするものである。The present invention has been made to solve the above-mentioned drawbacks of the prior art, and it is possible to cool the throw-away tip without using cutting oil, thereby extending the life of the tip and improving workability and economy. The purpose is to provide an excellent tool holder.

設し。(Means for Solving the Problems) In order to achieve the above object, the tool holder according to the present invention cools the chip by supplying cold air from inside the holder, and the gist thereof is as follows: In a throw-away tip cutting tool holder that holds a cutting tool with a tip attached to the tip of the shank, a hole for introducing cold air having one end opened in the tip mounting surface is bored inside the cutting tool.

以下に本発明を実施例に基づいて詳細に説明する。The present invention will be explained in detail below based on examples.

（実施例） 第１図は本発明の一実施例に係る冷風冷却装置付バイト
ホルダーを示している。(Embodiment) FIG. 1 shows a cutting tool holder with a cold air cooling device according to an embodiment of the present invention.

状態ではチップ間に隙間７が存在している。In the figure, 1 is a cutting tool held in a holder (not shown), and a throw-away tip 3 is attached to the tip of a shank 2. A clamp mechanism for restraining the tip 3 to the mounting surface 4 is built into the tip end of the shank 2 on the tip side.The clamp mechanism shown in FIG. 1 is a lever lock type having a clamp screw 5 and a clamp lever 6. By operating the clamp lever 5, the clamp lever 6 is rotated, and the chip 3 is brought into close contact with or separated from the mounting surface 4. Note that the mounting surface 4 is usually located at 2 points on the outer periphery of the chip.
It is shaped to enable surface restraint, and gaps 7 exist between the chips when the chips are attached.

略全面的に冷却することができる。In the present invention, the chip is cooled with cold air using the gap 7, and the chip 3 is directly cooled by blowing cold air from inside through the gap 7. To do this, a hole 8 for introducing cold air is bored inside the shank 2, one end of this hole 8 is opened facing the mounting surface 4, and the other end is opened at the rear end of the shank. An air cooler device [11] is connected to the portion 9 via a nipple 10. As a result, the cold air supplied from the air cooler device 11 flows inside the 68 as shown by the arrow in the figure, and is blown out from the gap 7 between the mounting surface 4 and the chip 3 to cool the chip 3 almost entirely. Can be done.

通常は一り０℃〜０℃程度の範囲内で選択すればよい。The air cooler device 11 may have an appropriate type of cold air generation and supply mechanism. For example, a small ultra-low temperature cooler that rotates compressed air at high speed and separates it into cold air and hot air by compression and expansion is convenient. The cold air supply temperature should be a temperature that can sufficiently cool the chip depending on the chip material, dimensions, shank dimensions, cutting conditions, cold air supply amount and speed, etc.
Usually, the temperature may be selected within the range of about 0°C to 0°C.

勿論、この温度範囲外であってもよい。Of course, the temperature may be outside this range.

し用の溝を形成してもよい。Although the cold air introduction hole 8 in the shank is of a straight type as shown in the figure, it may be a hole shaped to introduce cold air from the side. In addition, in order to increase the cooling efficiency, a heat-resistant sleeve 12 is installed in the hole, or the mounting surface 4, which has no gap in order to be in close contact with the outer periphery of the chip when mounting the chip, is installed as long as it does not cause any problem in terms of strength. A groove for blowing out cold air may be formed.

化も期待でき。(Effects of the Invention) As detailed above, according to the present invention, since the slow 7-way chip itself is directly cooled with cold air, there is no need to use cutting oil. problems can be solved all at once. Furthermore, since cooling can be adjusted to suit cutting conditions, it is expected that the life of the insert will be extended.
