절순한 본 발명의 목적은, 에어 실린더에 의해 작동되고, 에어가 공급되는 에어관로와, 선단부에 에어관로로 공급된 에어가 배출되는 배출구를 다수 가지며, 그 외형이 냉각성을 높이기 위한 요철 형태로 형성된 스폿 건과; 에어관로에 에어를 공급할 수 있게 에어실린더의 에어공급 및 배출호스상에 솔레노이드에 의해 개폐되는 에어퍼트와; 스폿건의 에어관로에 에어를 이송하는 에어호스로 구성된 것을 특징으로 하는 스폿 용접기의 스폿 건 냉각장치를 제공함으로써 달성된다.An object of the present invention is to operate by an air cylinder, and has a plurality of air pipes through which air is supplied, and a plurality of outlets through which air supplied to the air pipes is discharged from the front end thereof, and the outer shape is formed in the form of unevenness for improving cooling property. Spot tendon; An air putt opened and closed by a solenoid on the air supply and discharge hoses of the air cylinder to supply air to the air line; It is achieved by providing a spot gun cooling device of a spot welder, characterized in that it consists of an air hose for delivering air to the air line of the spot gun.
본 발명을 첨부한 실시예의 도면에 따라서 상세히 달성하면 다음과 같다.According to the drawings of the present invention attached to the present invention in detail as follows.
제 1 도는 본 발명에 의한 스폿 용접기의 스폿 건 냉각장치의 단면 구성도이고, 제 2 도는 제 1 도의 A-A선 단면도 이다.1 is a cross-sectional configuration diagram of a spot gun cooling apparatus of a spot welder according to the present invention, and FIG. 2 is a cross-sectional view taken along line A-A of FIG.
본 발명의 스폿 용접기의 스폿 건 냉각장치는, 에어 실린더(6)에 의해 작동되고, 에어가 공급되는 에어관로(11)와, 선단부에 에어관로(11)로 공급된 에어가 배출되는 배출구(12)를 다수 가지며, 그 외형이 냉각성을 높이기 위한 요철(14)형태로 형성된 스폿 건(10)과; 에어관로(11)에 에어를 공급할 수 있게 에어실린더의 에어공급 및 배출호스(19)(20)상에 솔레노이드(17)에 의해 개폐되는 에어포트(18)와; 스폿건(10)의 에어관로(11)에 에어를 이송하는 에어호스(16)로 구성된 것이다.The spot gun cooling apparatus of the spot welder of the present invention is operated by an air cylinder (6), and is provided with an air pipe line (11) through which air is supplied, and a discharge port (12) through which air supplied to the air pipe line (11) is discharged from the front end portion. Spot gun 10 having a plurality of, the outer shape is formed in the form of irregularities 14 for improving the cooling property; An air port 18 which is opened and closed by the solenoid 17 on the air supply and discharge hoses 19 and 20 of the air cylinder to supply air to the air line 11; It is composed of an air hose 16 for transporting air to the air conduit 11 of the spot gun 10.
상기와 같은 구성으로 된 본 발명은, 먼저 스폿 용접을 하기위해 에어 실린더(6)를 작동시키면 실린더 내부에 있는 압축공기가 솔레노이드 밸브(17)를 통해 배출되는데, 상기 배기에어를 스폿건(10)의 에어관로(11)와 연결하여 에어관로(11)를 따라 흐르면서 스폿 건(10) 내부를 냉각 시키면서 에어배출구(12)를 통해 대기중으로 배출되어 진다.According to the present invention having the above configuration, first, when the air cylinder 6 is operated to perform spot welding, the compressed air inside the cylinder is discharged through the solenoid valve 17, and the exhaust air is discharged to the spot gun 10. It is discharged into the atmosphere through the air outlet 12 while cooling the inside of the spot gun 10 while flowing along the air pipe 11 to the air pipe 11 of the.
한편, 스폿 건의 외측 표면상에 형성된 요철(14)에 의해 냉각효율을 증대시킬 수 있도록 하였다.On the other hand, the unevenness 14 formed on the outer surface of the spot gun allows the cooling efficiency to be increased.
즉, 스폿 건의 외측 형상을 제 2 도에 도시된 바와같이 요철(14) 형태로 형성하게 되면, 요철(14) 부위와 대기의 접촉면적이 넓어지게 되어 그만큼 냉각효율이 향상되므로서, 물을 사용하지 않고 공기만으로 스폿 건을 냉각시키더라도 물을 이용한 냉각방식에 버금가는 냉각효율을 달성할 수 있다.That is, when the outer shape of the spot gun is formed in the form of the unevenness 14 as shown in FIG. 2, the contact area between the unevenness 14 part and the atmosphere is widened, and the cooling efficiency is improved accordingly, and water is used. Even if the spot gun is cooled by air alone, the cooling efficiency similar to that of the water cooling method can be achieved.
상기 에어는 스폿 용접 1회시 에어실린더(6)가 왕복운동을 하게 되므로 2번에 걸쳐 에어를 에어공급관로(11)에 공급할 수가 있다.Since the air cylinder 6 reciprocates at the time of spot welding, the air can be supplied to the air supply line 11 twice.
이와같은 본 발명의 스폿 용접기의 스폿 건 냉각장치는, 스폿 건의 작동을 위해 스폿 건 상에 설치되는 에어실린더의 배기에어를 이용한 공냉식 냉각방식을 채택함으로써, 구조가 단순하되었고, 그로인한 제작 생산성을 향상시킴과 동시에 원가를 절감할 수 있으며, 스폿 건의 소형화로 설치공간을 최소화할 수 있는 효과를 나타낸다.The spot gun cooling apparatus of the spot welder of the present invention adopts an air-cooled cooling method using an exhaust air of an air cylinder installed on the spot gun for the operation of the spot gun, thereby simplifying the structure and thereby increasing the production productivity. In addition to improving costs, the company can reduce costs and minimize the installation space by miniaturizing spot guns.
