要があり、構造は複雑となり高価となる欠点があった。[Detailed explanation of the invention] Conventional vibration polishing equipment was configured to include an ultrasonic vibrator and transmit this vibration to the polishing tool using a horn for polishing. It has the disadvantage that it needs to be replaced, making the structure complicated and expensive.

に構成したものである。Therefore, the present invention uses magnetic fluid to generate vibrations, and includes an excitation coil connected to an excitation power source for generating a changing magnetic field, a magnetic iron core having a magnetic gap for generating a changing magnetic field, and a magnetic iron core having a magnetic gap for generating a changing magnetic field. A magnetic fluid that is sealed and filled in the magnetic fluid that repeatedly condenses and relaxes to produce vibrations when the excitation is turned on and off, and a vibration output end that has a spout at the other end, one end of which is on the magnetic core side, and a supply of polishing liquid. It consists of a nozzle with a mouth, and is configured to transmit ultrasonic vibrations of a magnetic fluid vibrated by a changing magnetic field to the polishing liquid supplied from the supply opening into the nozzle, and eject it, thereby performing polishing with vibrating abrasive grains. This is what I did.
磁性流体は周知のように液相中にマグネタイト等の微細
な強磁性粉末を安定に分散させたコロイド溶液で、磁場
によって凝集、固液分離が起らない溶液である。As is well known, a magnetic fluid is a colloidal solution in which fine ferromagnetic powder such as magnetite is stably dispersed in a liquid phase, and is a solution that does not undergo agglomeration or solid-liquid separation due to a magnetic field.
従ってこれに変化磁界を作用させれば磁性流体全体が凝
縮と弛緩を繰り返すことによって液全体が振動して液体
振動を発生する。Therefore, when a changing magnetic field is applied to this, the entire magnetic fluid repeats condensation and relaxation, causing the entire liquid to vibrate and generate liquid vibration.
振動は変化磁界の周波数によって容易に任意の周波数に
制御でき、複雑な超音波振動子を設けなくても容易に液
体超音波振動を発生することができる。The vibration can be easily controlled to any frequency by changing the frequency of the magnetic field, and liquid ultrasonic vibration can be easily generated without providing a complicated ultrasonic vibrator.
そしてこの液体振動を含む研摩液に伝達して研摩加工す
るとかでき便利な加工装置が簡単に得られる。A convenient processing device that can perform polishing by transmitting this liquid vibration to the polishing liquid containing it can be easily obtained.
以下図面の実施例により説明する。The present invention will be explained below using embodiments shown in the drawings.
第１図は磁性流体の液体振動を砥粒を混合した研摩液に
伝えて研摩加工する例で、１は磁気鉄心、２は励磁コイ
ルで、交流、高周波電源により付勢される。FIG. 1 shows an example of polishing by transmitting liquid vibrations of a magnetic fluid to a polishing solution mixed with abrasive grains. 1 is a magnetic core, 2 is an excitation coil, and is energized by an alternating current, high frequency power source.
３は鉄心１の磁気間隙に周りに弾性ゴム等を包囲して漏
れないようにして充填した磁性流体、４は鉄心１に固定
して取り付けた先端先細りのノズルで、内部にポンプ５
によって砥粒を混合した研摩液６が供給され、ノズル４
の先端の噴出口４ａから噴出する。3 is a magnetic fluid filled into the magnetic gap of the iron core 1 by surrounding it with elastic rubber or the like to prevent leakage; 4 is a nozzle with a tapered tip that is fixedly attached to the iron core 1, and a pump 5 is installed inside it.
A polishing liquid 6 mixed with abrasive grains is supplied to the nozzle 4.
It is ejected from the ejection port 4a at the tip of the .
７はノズル４を振動させる振動コイルである。7 is a vibration coil that vibrates the nozzle 4.
コイル２に高周波電流を流すことによって磁極間隙に充
填しである磁性流体３が凝縮と弛緩を繰り返して振動す
る。By passing a high frequency current through the coil 2, the magnetic fluid 3 filling the gap between the magnetic poles repeatedly condenses and relaxes, causing it to vibrate.
振動数は通常ｌＫ〜４０ＫＨｚ程度まで容易に利用でき
るが、これにより磁性流体３の液体振動が発生し、ポン
プ払５から供給されたノズル内の研摩液６に振動が伝播
作用し、研摩液６内の砥粒が振動する。Normally, the frequency of vibration can be easily used from about 1K to 40KHz, but this causes liquid vibration of the magnetic fluid 3, which propagates to the polishing liquid 6 in the nozzle supplied from the pump wiper 5, and the polishing liquid 6 The abrasive grains inside vibrate.
そして砥粒の混合した研摩液はノズル先端の噴出口４ａ
から振動しながら噴出し、ノズル４先端を研摩部分に向
けておくことにより振動噴出する研摩液、砥粒によって
容易に目的の研摩加工ができる。The polishing liquid mixed with abrasive grains is then sprayed at the spout 4a at the tip of the nozzle.
By directing the tip of the nozzle 4 toward the part to be polished, the polishing liquid and abrasive grains that are vibrated can easily perform the desired polishing process.
このとき、更に励磁コイル７を交流磁励してノズル４を
振動させることによって研摩液の噴出が振動的となり研
摩加工は更に向上する。At this time, the nozzle 4 is vibrated by further alternating current magnetic excitation of the excitation coil 7, whereby the ejection of the polishing liquid becomes vibratory and the polishing process is further improved.
第２図は第１図における研摩液噴出ノズルの側面にナイ
フ状の切欠開口４ｂを設けて、研摩液をここから噴出す
るようにしたもので、これによればコーナ一部の稜線加
工等には効果的である。Fig. 2 shows an example in which a knife-shaped notch opening 4b is provided on the side surface of the abrasive liquid spouting nozzle in Fig. 1 so that the abrasive liquid is ejected from there. is effective.

れに変化磁界を作用して振動を発生するようにしたから
簡単に超音波等の任意の周波数振動を発生でき、これを
砥粒へ伝播作用用させることにより目的とする研摩を容
易に行なうことができる。As mentioned above, the polishing device of the present invention uses a magnetic fluid and applies a changing magnetic field to it to generate vibrations, so it can easily generate vibrations of any frequency such as ultrasonic waves, which can be used to generate vibrations on the abrasive particles. The desired polishing can be easily achieved by using the propagation action.
そして振動発生装置の構造が従来の超音波振動装置の如
き複雑な構成を有することなく、磁性流体に変化磁界を
作用させる磁界発生装置を設けるだけであるから極めて
簡単に、そして安価に構成することができる。Moreover, the structure of the vibration generator does not have a complicated structure like the conventional ultrasonic vibrator, and it can be constructed extremely easily and at low cost because it only requires a magnetic field generator that applies a changing magnetic field to the magnetic fluid. Can be done.
