ワークから除去するものである。2. Description of the Related Art Usually, fine burrs may remain on a work after the work is molded or processed. Conventionally, in order to remove fine burrs remaining on a work, ultrasonic deburring cleaning is performed on the work, for example. In ultrasonic deburring cleaning, ultrasonic waves are radiated to the cleaning liquid to generate cavities in the cleaning liquid, and the shock waves (micro jets) generated when the cavitation collapses are immersed in the cleaning liquid. This is to remove the burr of the work from the work.

ので溶存酸素量を確認することにより全溶存気体量を知
ることができるからである。As a result of extensive studies on the conditions under which the cavitation occurs, the present inventor has found that the lower the concentration of the gas dissolved in the cleaning liquid is, the more easily cavitation occurs. Proposed a cleaning device for deburring and cleaning a work by degassing so that the amount of dissolved oxygen in the cleaning liquid becomes 0.5 ppm or less.
Here, the amount of dissolved oxygen is used as an index of the degassing state of the cleaning liquid. Normally, the gas dissolved in the cleaning liquid is air, and the composition of air is almost constant because oxygen: nitrogen≈1: 4. This is because the total dissolved gas amount can be known by checking the oxygen amount.
【０００４】しかし、洗浄液に長時間にわたって超音波

た。However, if ultrasonic waves are radiated to the cleaning liquid for a long time, the burr may be difficult to be removed even if the amount of dissolved oxygen in the cleaning liquid is 0.5 ppm or less.

実なバリ取り洗浄を行うものである。Further, the present inventor previously found that Japanese Patent Application No. 62-1
Japanese Patent No. 85774 (JP-A-1-34647) has proposed an ultrasonic deburring and cleaning apparatus in which the temperature of the cleaning liquid is 0 ° C or lower. According to this device, a work burr is fragile by immersing the work in a cleaning liquid having a liquid temperature of 0 ° C. or less,
By exposing the fragile burr to the shock wave, deburring and cleaning can be surely performed.
【０００６】しかし、この場合ワークはプラスチック部
品等の低温時に硬化が進行してもろくなる性質のものに
限られ、アルミニウム合金等の金属製のワークの場合は
温度を下げただけでは十分なバリ取り効果を得ることが
できなかった。In this case, however, the work is limited to those having the property of becoming brittle even if the hardening progresses at a low temperature such as plastic parts, and in the case of a work made of a metal such as an aluminum alloy, deburring is sufficient only by lowering the temperature. I couldn't get the effect.

【発明が解決しようとする課題】かかる不都合を解消し

浄を行っても高いバリ取り効果を持続することができる
超音波バリ取り洗浄装置を提供することを目的とする。It is possible to eliminate such inconvenience and completely remove burrs on a work by ultrasonic deburring cleaning, and to obtain a high deburring effect even if ultrasonic deburring and cleaning are performed for a long time. An object of the present invention is to provide an ultrasonic deburring / cleaning device that can maintain the above.

知見した。The present inventor has confirmed that the temperature of the cleaning liquid rises when ultrasonic waves are radiated to the cleaning liquid for a long time. Furthermore, it was found that the higher the temperature of the cleaning liquid, the slower the cavitation collapse when ultrasonic waves were radiated to the cleaning liquid. Is difficult to be done and the temperature of the cleaning liquid is 30
It has been found that even if the temperature is lower than 0 ° C, if the dissolved oxygen amount of the cleaning liquid exceeds 2 ppm, it is difficult to remove the burr remaining on the work.
【０００９】また、水系の洗浄液では、溶存酸素量を
０．０１ｐｐｍ未満とすることは実質的に困難である。
それは、洗浄槽に供給された洗浄液の液面から洗浄液中
に空気が溶解するからである。In addition, it is practically difficult to make the amount of dissolved oxygen less than 0.01 ppm in an aqueous cleaning solution.
This is because air dissolves in the cleaning liquid from the liquid surface of the cleaning liquid supplied to the cleaning tank.

A cleaning tank containing a cleaning liquid, and an ultrasonic vibrator provided at the bottom of the cleaning tank, and ultrasonic waves are emitted from the ultrasonic vibrator to the cleaning liquid to clean the workpiece immersed in the cleaning liquid. In the ultrasonic cleaning device, the cleaning liquid is degassed so that the dissolved oxygen amount becomes 0.01 to 2 ppm, and the temperature of the cleaning liquid is set to 30 ° C. or lower.

By degassing so as to be 01 to 2 ppm, it becomes possible to generate a relatively large amount of cavitation in the cleaning liquid, and further, by setting the liquid temperature of the cleaning liquid to 30 ° C. or less, the collapse rate of cavitation can be increased. Allows to be relatively fast. This increases the number of shock waves generated per unit time when ultrasonic waves are radiated to the cleaning liquid, and enables deburring and cleaning.

とができる。As is clear from the above, according to the present invention, a cleaning liquid which is degassed so that the amount of dissolved oxygen is 0.01 to 2 ppm and which has a liquid temperature of 30 ° C. or lower is used. Thus, when ultrasonic waves are radiated to the cleaning liquid, a relatively large amount of cavitation is generated in the cleaning liquid, and the cavitations are broken at a relatively high speed to obtain a shock wave having a high impact force. As a result, the work immersed in the cleaning liquid is exposed to a shock wave having a high impact force, so that the burr can be completely removed from the work.

A large amount of cavitation can always be generated by maintaining the dissolved oxygen amount of the cleaning liquid at 2 ppm or less. Furthermore,
Since the cooling means is provided in the cleaning liquid circulation path, even if ultrasonic cleaning is performed for a long time, the temperature of the cleaning liquid is 30
Cavitation can be destroyed at a fast rate by keeping the temperature below ℃.
