Abstract

PURPOSE: An ultrasonic machine is provided to improve productivity as well as to solve the problems of the former cooling method using cooling water by cooling a nickel vibrator with more effective method. CONSTITUTION: A work table is installed on a frame. When a motor rotates a machining bar, a vibrator(7) is vibrated and machining material on the machining bar is machined. The vibrator has a coil(12) wound upon plural piled-up nickel plates(11), and a magnet(13) set at the end to form a nickel vibrator(14). A conical ultrasonic horn(15) is connected to the front end of the nickel vibrator, and a machining pin(16) is fixed to the front side. A cooling cover(19) having a space portion(18) is mounted around the nickel vibrator. A cooling fan(21) connected with a motor(20) is set on a side while several vent holes are formed on the other side. When an electric current flows to the coil through the transformer, the nickel vibrator is vibrated. 20000-25000 times of waves are generated per second. As the machining pin generates fine vibration to machine the material, hot heat is generated from the nickel plates. To cool the nickel plates, the cooling fan is rotated by the motor(20). The nickel plates are automatically cooled by a wind blowing from the cooling fan. Therefore, the nickel plates are not molten and the performance of the ultrasonic machine is kept regular with generating regular waves all the time.

Description

초음파 가공기{ULTRASONIC PROCESSING MACHINE}Ultrasonic Processor {ULTRASONIC PROCESSING MACHINE}

본 발명은 초음파 가공기에 관한 것으로서, 보다 구체적으로는 니켈 진동자를 진동시켜 다이아몬드나 루비, 유리, 초경합금, 반도체, 전자현미경 시료 등과같은 고강도의 초정밀 소재를 가공함에 있어서, 니켈 진동자의 진동시 발생되는 고열을 보다 효율적으로 냉각시켜 음파발생을 항상 일정하게 유지시킬 수 있게 함으로써, 가공성을 보다 좋게 하고 가공시간을 단축시켜 생산성을 크게 향상시킬 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic processing machine, and more particularly, to vibrating a nickel vibrator to process high-strength, high-precision materials such as diamond, ruby, glass, cemented carbide, semiconductors, electron microscope samples, and the like. By cooling more efficiently, the sound wave generation can be kept constant at all times, thereby improving the processability and shortening the processing time, thereby greatly improving productivity.

일반적으로 지금까지는 주로 니켈 진동자를 냉각시킴에 있어서, 니켈 진동자의 주위를 절연체로 피복시킨 뒤, 그 주위에 냉각수를 공급, 순환시키는 방식을 취하고 있었다.In general, up to now, in cooling a nickel vibrator, the surroundings of the nickel vibrator are covered with an insulator, and a cooling water is supplied and circulated therein.

그러나 이와 같은 종래의 니켈 진동자 냉각방식은 초음파 가공시, 니켈 진동자에서 연속적으로 발생되는 고열을 냉각시키기 위하여 냉각수를 급속히 냉각시켜 이를 니켈 진동자에 연속적으로 공급, 순환시켜야 되기 때문에, 구조가 복잡해지고 생산 원가가 많이 요구되는 결함과 함께, 장기간 사용시, 절연재 내부로 냉각수가 침투되어 니켈 진동자가 작동되지 못하게 되는 폐단이 있었고, 또한 냉각수에 불순물이 섞여 배관 파이프가 막힐 경우, 니켈 진동자가 냉각되지 못하여 니켈판이 타서 못쓰게 되는 문제가 있었다.However, in the conventional nickel oscillator cooling method, since the cooling water must be rapidly cooled and continuously supplied and circulated to the nickel oscillator in order to cool the high temperature continuously generated in the nickel oscillator, the structure becomes complicated and the production cost is increased. In addition to the defects that require a lot of defects, there is a closed end where the coolant penetrates into the insulating material and prevents the nickel oscillator from operating during long-term use.In addition, if the pipe pipe is clogged due to impurities in the coolant, the nickel oscillator cannot be cooled and burned. There was a problem that could not be used.

또한 이와 같은 종래의 냉각수에 의한 냉각방식의 경우, 일정시간 마다 냉각수 전체를 냉각시키기 위하여 가동을 오랜시간 멈춰야 하는 폐단이 있었다.In addition, in the case of the conventional cooling system using the cooling water, there is a closed end of stopping the operation for a long time in order to cool the whole cooling water every predetermined time.

본 발명은 이와 같은 종래의 문제점을 감안하여 연구된 것으로서, 본 발명의 초음파 가공기는 보다 효율적인 방법으로 니켈 진동자를 냉각시킴으로서, 종래의 냉각수에 의한 냉각방식이 갖고 있는 제반 결점을 해소하여 생산성을 크게 향상시킬 수 있도록 한 것을 목적으로 한다.The present invention has been studied in view of such a conventional problem, and the ultrasonic processor of the present invention cools the nickel vibrator in a more efficient manner, thereby eliminating all the shortcomings of the conventional cooling method by the cooling water, thereby greatly improving productivity. The purpose is to make it possible.

그 목적을 달성키 위하여 본 발명은 니켈 진동자의 외부에 공간부가 형성된 냉각덮개를 설치하고 그 일측에 모터가 연결된 냉각팬과, 다른 일측에 통기공을 형성함으로써, 초음파 가공기의 가동시, 모터가 회전하여 냉각팬이 가동하면 냉각팬에서 발생되는 바람에 의하여 니켈 진동자가 자동으로 연속적으로 냉각되도록 한 것을 특징으로 한다.In order to achieve the object of the present invention, by installing a cooling cover formed with a space on the outside of the nickel oscillator and forming a cooling fan connected to the motor on one side and a ventilation hole on the other side, the motor rotates during operation of the ultrasonic processing machine. When the cooling fan is operated, the nickel vibrator is automatically cooled continuously by the wind generated from the cooling fan.

이하 본 발명의 바람직한 실시예를 첨부도면을 참조하며 구체적으로 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 1 은 본 발명이 적용된 초음파 가공기의 일실시예의 외형사시도, 도 2 와 도 3 및 도 4 는 본 발명의 내부 구조를 보인 정단면도와 동 측단면도 및 동 평면도로서, 프레임(1) 상에 작업대(2)가 설치되어 모터(3)가 가공봉(4)을 회전시키면, 프레임(1)의 후측에 설치된 가이드축(5)에 장착되어 트랜스(6)와 연결된 진동장치(7)가 진동을 일으켜 상기 가공봉(4)에 설치된 가공물을 가공하게 된다.1 is an external perspective view of an embodiment of an ultrasonic processing machine to which the present invention is applied, and FIGS. 2 and 3 and 4 are a front sectional view and a side sectional view and a plan view showing an internal structure of the present invention, on a work table on a frame 1. (2) is installed and the motor (3) rotates the processing rod (4), the vibration device (7) connected to the transformer (6) is mounted on the guide shaft (5) installed on the rear side of the frame (1) to vibrate To process the workpiece installed in the processing rod (4).

그리고 상기 진동장치(7)는 내부에 여러겹으로 중첩된 다수의 니켈판(11)의 주위에 코일(12)이 권회되어 있고, 그 단부에 자석(13)이 설치되어 니켈 진동자(14)를 구성하고 있으며, 이 니켈 진동자(14)의 선단부에는 원추형의 초음파혼(15)이 연결 고정되어 있으며, 그 전방에는 가공핀(16)이 연결 고정되어 있다.In the vibrator 7, the coil 12 is wound around a plurality of nickel plates 11 superimposed in several layers, and a magnet 13 is installed at an end thereof to provide a nickel vibrator 14. The conical ultrasonic horn 15 is fixedly connected to the distal end of the nickel vibrator 14, and the processing pin 16 is fixedly connected to the front thereof.

그리고 상기 니켈 진동자(14)의 주위에는 공간부(18)가 형성된 냉각덮개(19)가 설치되어 있고, 그 일측에 모터(20)가 연결된 냉각팬(21)이 부착되어 있으며,다른 일측에는 수개의 통기공(22)이 형성되어 있다.And around the nickel vibrator 14 is provided with a cooling cover 19 formed with a space 18, a cooling fan 21 is connected to one side of the motor 20, the other side is Two vent holes 22 are formed.

이와 같이 구성된 본 발명의 초음파 가공기는 트랜스(6)를 통하여 코일(12)에 전류가 흐르면, 니켈 진동자(14)가 발진되어 초당 20,000-25,000번의 음파가 발생하면서 가공핀(16)이 미세한 진동을 일으켜 가공물을 가공시킬 수 있게 된다. 이때 니켈판(11)에는 발진에 의해 아주 높은 열이 발생하게 되는데, 이 열을 냉각시키지 않을 경우, 니켈판(11)이 가열되어 타게 될 뿐만 아니라, 음파 발생을 저하시켜 가공성을 크게 떨어뜨리는 원인이 된다.In the ultrasonic processor of the present invention configured as described above, when a current flows in the coil 12 through the transformer 6, the nickel vibrator 14 is oscillated to generate 20,000-25,000 sound waves per second, and the processing pin 16 generates minute vibrations. To be able to process the workpiece. At this time, very high heat is generated in the nickel plate 11 by oscillation. If the heat is not cooled, the nickel plate 11 is not only heated and burned, but also causes the sound wave to be degraded, thereby greatly reducing workability. Becomes

이를 위하여 본 발명은 니켈 진동자(14)의 외부에 설치된 냉각덮개(19)의 일측에 냉각팬(21)이 설치됨으로써, 모터(20)가 작동하여 냉각팬(21)이 회전하면, 냉각팬(21)에서 발생하는 바람에 의하여 니켈판(11)이 자동으로 냉각됨으로써, 연속적으로 초음파 가공기를 가동시켜도 니켈판(11)이 탈 열려가 없을뿐만 아니라, 항상 일정한 음파가 발생되어 초음파 가공기의 성능을 일정하게 유지할 수 있게 되어 가공성을 크게 항상 시킬 수 있는 장점이 있다.To this end, in the present invention, the cooling fan 21 is installed at one side of the cooling cover 19 installed on the outside of the nickel vibrator 14, so that when the motor 20 operates and the cooling fan 21 rotates, the cooling fan ( 21, the nickel plate 11 is automatically cooled by the wind generated by 21), so that the nickel plate 11 is not detached even if the ultrasonic wave machine is continuously operated, and constant sound waves are always generated to improve the performance of the ultrasonic wave machine. Since it can be kept constant, there is an advantage that can always be greatly improved machinability.

또한 종래의 수냉식에 의한 냉각방식의 경우에는 냉각수에 의해 음파가 흡수되어 감소되기 때문에 가공핀(16)의 길이를 음파가 전달될 수 있는 일정한 길이 이하로 짧게 유지시켜야 하므로, 수시로 가공핀(16)을 교체하게 되어 교체에 따른 부품비 및 교체작업으로 인해 원가 상승의 요인이 발생하였으나, 본 발명의 초음파 가공기에 의하면, 냉각수와 같은 음파 흡수 물질이 없이 바로 냉각되므로, 니켈 진동자(14)에 항상 일정한 음파가 유지되기 때문에 가공핀(16)을 길게 설치할 수 있게 되어 원가를 크게 절감시킬 수 있는 장점이 있다.In addition, in the conventional water-cooled cooling method, since the sound waves are absorbed and reduced by the cooling water, the length of the processing pins 16 should be kept shorter than a predetermined length to which sound waves can be transmitted, and thus, the processing pins 16 from time to time. The cost of the increase in cost due to the replacement part cost and replacement work caused by the replacement, but according to the ultrasonic processor of the present invention, since it is directly cooled without the sound absorbing material such as coolant, the sound wave is always constant in the nickel vibrator 14 Since it is possible to install the processing pin 16 long, there is an advantage that can greatly reduce the cost.

이상에서는 본 발명을 특정한 실시예에 의거하여 설명하였으나, 본 발명은 본 발명의 기술적 범위내에서 많은 변형예가 있을 수 있으며, 상기 실시예에 본 발명의 기술적 범위가 한정되는 것은 물론 아니다.In the above, the present invention has been described based on specific embodiments, but the present invention may have many modifications within the technical scope of the present invention, and the technical scope of the present invention is not limited to the above embodiments.

따라서 이와 같은 본 발명의 초음파 가공기에 의하면, 보다 간단한 구조로서 니켈 진동자를 냉각시킬 수 있게 됨으로써, 가공성이 좋은 초음파 가공기를 보다 낮은 생산원가로 가동시킬 수 있는 효과가 있다.Therefore, according to the ultrasonic processor of the present invention, it is possible to cool the nickel vibrator with a simpler structure, whereby the ultrasonic processor having good processability can be operated at a lower production cost.
