本考案は、 超音波装置の作業取手内部に於いて、 振動子 ·ホーン ·ェ 具ホルダへと伝達される超音波振動を駆動源として工具ホルダに当接し た工具が駆動する際、 その工具のシャンクに設けたッバが工具ホルダの 開口端面において広い面積にわたり均一に当接し、 長手方向に滑らかで 力強い駆動を行なう。 そして、 駆動源部が工具ホルダの開口端面である がゆえに、 連続して長時間駆動させることによる変形はおきにくく、 ま た、 たとえ変形が生じ fc場合でも、 目視による状況判断が容易なため、 工具のッバも工具ホルダの開口端面の両方とも、 容易に手早く修正を行 なうことができる。 背景技術 According to the present invention, when a tool abutting on a tool holder is driven by ultrasonic vibration transmitted to a vibrator, a horn, and a tool holder inside a work handle of the ultrasonic apparatus, the tool is driven. The shank provided on the shank makes uniform contact over a wide area at the open end face of the tool holder, and provides smooth and powerful driving in the longitudinal direction. Since the drive source is the open end face of the tool holder, deformation due to continuous driving for a long time is unlikely to occur, and even if deformation occurs, it is easy to visually determine the situation. Both the tool cover and the open end face of the tool holder can be easily and quickly corrected. Background art
従来、 この種の工具ホルダとしては （例えば、 昭和 5 5年に本考案者 が開発し、 本出願人が発売した超音波彫刻機 <名称：クラフ トマスター >に装着してあるホルダ） 、 第 5図と第 6図に示すとおり、 その後部に ホーン締付ねじ b 1を有し、 これをホーン Aへ螺合 g¾め付けて装着され る。 ホーン Aから伝達する超音波振動は、 ホーン締付ねじ b 1を通じて 工具ホルダ Bへ伝わる。 そして、 第 5図に示す工具ホルダ Bには、 工具 Dのシャンク部 d 1を挿し込み可能な丸穴 b 2を設けてあり、 工具ホル ダ Bにねじ込まれ fc締付用のねじ Cで工具 Dのシャンク部 d 1を押圧固 定し、 さらに工具 Dの先端部 d 2へ超音波振動を伝達して、 ストローク は小さいがきめこまかさを活かす研磨仕上げ、 彫刻作業等に使用する方
法と、 第 6図に示すように該工具ホルダ Bから締付用のねじ （第 5図の C ) を取り外して、 工具 Dのシャンク部 d 1 を工具ホルダ Bの丸穴 b 2 へ挿し込み、 シャンク端面 d 3を穴底面 b 3に当接させ、 超音波振動を 駆動源として工具 Dをフリーに駆動させて、 金鎚ですこすこ く よ うな大きな ストロークを活かす作業に使用する方法とが知られている。 Conventionally, as a tool holder of this type (for example, a holder attached to an ultrasonic engraving machine <name: Craft Master> developed by the present inventors in 1980 and released by the present applicant), As shown in Fig. 5 and Fig. 6, a horn tightening screw b1 is provided at the rear part, and this is screwed to horn A and mounted. The ultrasonic vibration transmitted from horn A is transmitted to tool holder B through horn tightening screw b1. The tool holder B shown in Fig. 5 has a round hole b2 into which the shank d1 of the tool D can be inserted, and is screwed into the tool holder B. Pressing and fixing the shank d1 of D, and transmitting ultrasonic vibration to the tip d2 of the tool D, which is used for polishing, engraving, etc., with a small stroke but making use of fineness As shown in Fig. 6, remove the tightening screw (C in Fig. 5) from the tool holder B and insert the shank d1 of the tool D into the round hole b2 of the tool holder B. The shank end face d3 is brought into contact with the bottom face b3 of the hole, the tool D is driven freely using ultrasonic vibration as a drive source, and the method is used for work that makes use of a large stroke like a small hammer. Are known.
従来の技術の使用方法として、 前述、 第 5図においては問題なく、 後 述、 第 6図において、 As a method of using the conventional technology, there is no problem in FIG. 5 described above, and in FIG.
従来の技術のごとく、 工具ホルダ Bの穴底面 b 3を駆動源部として、 ェ 具 Dのシャンク端面 d 3を該穴底面 b 3に当接させて工具 Dをフリ一に 駆動させるやり方は、 工具ホルダ Bの外径寸法により丸穴 b 2の直径寸 法に限界があり、 したがって穴底面 b 3の面積も狭く限られていて、 駆 動力が小さいので効率悪く僅かな種類の仕事にしか対応できず、 それと ても、 作業に要する時間が非常にかかるという問題点を有していた。 As in the prior art, the method of driving the tool D free by making the shank end face d3 of the tool D abut the hole bottom face b3 with the hole bottom face b3 of the tool holder B as a drive source part is as follows. There is a limit to the diameter of the round hole b2 due to the outer diameter of the tool holder B, so the area of the hole bottom b3 is limited and small. However, it had a problem that the time required for the work was extremely long.
また、 駆動源部である工具ホルダ Bの穴底面 b 3は連続して工具 Dを 駆動させることにより徐々にではあるが荒れや変形を起こし、 そして、 工具 Dのシャンク端面 d 3も駆動を繰り返すことによりバリや変形を発 生するが、 特に、 バリが穴底にくいこむと当然のことながら駆動能力は 低下し、 更には工具 Dがフリーに^動しなくなり、 時には工具 Dを丸穴 b 2から取り出しにくくなるので、 頻繁にこれら変形を修正しなければ ならないという繁雑な問題点を有していた。 In addition, the bottom surface b 3 of the tool holder B, which is the drive source, is gradually roughened and deformed by continuously driving the tool D, and the shank end surface d 3 of the tool D is also driven repeatedly. However, if the burr does not easily reach the bottom of the hole, the driving capacity will naturally decrease, and the tool D will not move freely. It had a complicated problem that these deformations had to be corrected frequently because it became difficult to remove them.
更に、 工具 Dのシャンク端面 d 3の修正は容易にできるものの、 工具 ホルダ Bの穴底面 b 3の修正は目視しにく く状況判断が非常に困難であ る為に修正は非常に難しく、 時間を要し、 そのぶん作業性が低下すると いう問題点を有していた。 Furthermore, although the shank end face d3 of the tool D can be easily corrected, the correction of the hole bottom face b3 of the tool holder B is difficult to visually observe, and the situation determination is very difficult. It took time and had the problem that workability deteriorated accordingly.
本考案は、 従来の技術の有するこのような問題点に鑑みてなされ も のであり、 その目的とするところは、 超音波の特徴である周波数の高さ、
そして、 強力な振動をいかんなく発揮させ、 駆動源としてそのもてる力 を十分に活かして彫刻、 打刻、 切削等を行なうことができ、 そして、 駆 動を繰り返し行なうことによる工具と工具ホルダに発生する変形等は駆 動することに fcいしてほとんど影響がなく、 また、 その変形の修正はと ても容易に行なうことのできる工具と工具ホルダを提供しようとするも のである。 発明の開示 The present invention has been made in view of the above-mentioned problems of the conventional technology, and aims at the high frequency, which is a characteristic of ultrasonic waves. It is capable of exerting powerful vibrations, making full use of its power as a drive source for engraving, embossing, cutting, etc., and for tools and tool holders through repeated driving. The generated deformation has little effect on the driving force, and it is intended to provide a tool and a tool holder that can easily correct the deformation. Disclosure of the invention

本考案をより詳細に説述するために、 添付の図面に従ってこれを説明 する。 第 1図に示した工具 1は直径 4 . 5 mmの鋼丸棒から旋盤加工した ものであり、 ちなみにシャンク部 1 cの直径は 2 . 5 mm、 ツバ l bの直 径は 4 . 5 mmのままを用いて、 工具先端 1 aには打刻用の丸 fcがねが成 形してあり、 ツバ 1 bの後方のシャンク部 1 cの長さは 1 5 mm程度にな つている。 The present invention will be described in more detail with reference to the accompanying drawings. The tool 1 shown in Fig. 1 is a lathe machined from a 4.5 mm diameter steel round bar.The diameter of the shank 1c is 2.5 mm, and the diameter of the collar lb is 4.5 mm. Using a tool as it is, a round fc spring for embossing is formed at the tool tip 1a, and the length of the shank 1c behind the collar 1b is about 15 mm.
一方、 工具ホルダ 2の基本的構成は、 従来のものと同様、 後部にホー ン締付ねじ 2 cを有し、 外周面にはスパナ装着用に面取された平角部 2 bを有している。 本体部分の略中心部軸方向に、 先端面に開口する丸穴 3が十分に深く設けられている。 ちなみに丸穴 3の直径は 2 . 5 mm少々、 つまり、 工具 1のシャンク部 1 c直径 2 . 5 mmが丸穴内で、 力強く、 且 つ、 がたつくことなく精密で滑らかな駆動を行なわせてなる寸法に形成 されている。 On the other hand, the basic configuration of the tool holder 2 is the same as that of the conventional one, with a horn tightening screw 2c at the rear and a flat portion 2b chamfered for mounting a spanner on the outer peripheral surface. I have. A round hole 3 opening in the distal end surface is provided sufficiently deep in the axial direction of substantially the central portion of the main body. By the way, the diameter of the round hole 3 is a little 2.5 mm, that is, the shank portion 1 c of the tool 1 2.5 mm in diameter is powerful, and has a precise and smooth drive without rattling in the round hole. It is formed to dimensions.
つまり、 この超音波加工用工具は、 第 1図に示したように、 工具 1の
シャンク部 1 cを工具ホルダ 2の丸穴 3内へ揷し込み、 工具 1のツバ 1 を工具ホルダ 2の開口端面 2 aに当接させ、 工具 1をフリーに駆動さ せる構成とされている。 In other words, as shown in Fig. 1, this ultrasonic machining tool The shank 1 c is inserted into the round hole 3 of the tool holder 2, and the collar 1 of the tool 1 is brought into contact with the opening end face 2 a of the tool holder 2, and the tool 1 is driven freely. .
尚、 図 3に示した工具先端 1 a ' には、 彫刻用たがねが成形されてい るのでそのたがねの刃先方向をしつかり定めておく必要があり、 そのた めに工具 1のシャンク部 1 cの後方において、 長さ 7 mm程を深さ 0 . 6 mmカッ トして凹部 1 dを設けてある。 そして、 工具ホルダ 2の丸穴 3に おいて、 上記シャンク部 1 cを挿し込んだ状態での凹部 1 dに対応する 場所に凸部 4をロー付けにて埋設してあり、 その高さは、 たがねの刃先 が方向変化するのを防ぎ、 且つ、 シャンク部 1 cが滑らかに駆動を行な うのを阻止しないように調整してある。 産業上の利用可能性 In addition, since a chisel for engraving is formed on the tool tip 1a 'shown in Fig. 3, it is necessary to firmly determine the cutting edge direction of the chisel. Behind the shank 1c, a recess 1d is provided by cutting a length of about 7mm to a depth of 0.6mm. Then, in the round hole 3 of the tool holder 2, a convex portion 4 is embedded by brazing at a position corresponding to the concave portion 1d in a state where the shank portion 1c is inserted, and the height thereof is In addition, the cutting edge of the chisel is adjusted so as not to change its direction and not to prevent the shank portion 1c from being driven smoothly.
