Abstract

PURPOSE: A brake device of a pneumatic cylinder is provided to prevent an accident and to improve welding efficiency by installing the brake device in the pneumatic cylinder in such a manner that the pneumatic cylinder is stopped at an intermediate stroke position. CONSTITUTION: An air inlet hole(7) is formed in a cylinder tube(6), a cylinder head cover(2) and a cylinder end cover(3). A spring(8) is provided to elastically support a piston(4) of a pneumatic cylinder. A push button(10) and a ball(9) are provided to discharge pneumatic pressure introduced from a solenoid valve(1) and to discharge pneumatic pressure between a brake piston(5) and the cylinder end cover(3). Air is supplied into a gap formed between the brake piston(5) and the cylinder end cover(3) along the air inlet hole(7), thereby pushing up the brake piston(5). Thus, the brake piston(5) makes contact with a locking protrusion(13) formed in the cylinder tube(6). Since a cylinder is fixed to a piston rod(11) due to elastic force of the spring(8), the piston(4) makes contact with the brake piston(5) so that the piston(4) is prevented from moving backward.

Intermediate stop by (19), when the stopper handle 16 is lowered, the locking jaw 19 is released from the brake body 15, the piston 4 is completely retracted.

상기한 바와같이 종래의 브레이크 장치는 중간 정지시 브레이크 몸체와 걸림턱 사이에 사람의 손이 끼어 안전 사고가 종종 발생하고 피스톤 완전후퇴시 한손은스토퍼를 내려야하기 때문에 다른 한손으로 용접기의 무게를 지탱 해야 하는 문제점이 있었다.As described above, the conventional brake device has to support the weight of the welder with the other hand because the human hand is caught between the brake body and the locking jaw during the intermediate stop, and a safety accident often occurs. There was a problem.

본 발명의 목적은 종래의 문제점을 개선하기 위한 것으로 종래의 브레이크장치를 실린더에 내장시켜 안전 사고를 막고 더 좋은 용접 효과를 제공하기 위한 것이다.An object of the present invention is to improve the conventional problems, to incorporate a conventional brake device in the cylinder to prevent a safety accident and provide a better welding effect.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 솔레노이드밸브(1)의 절환에 따라 실린더 튜브(6)와 이를 고정하는 실린더헤드 커버(2) 및 실린더엔드 커버(3) 사이로 피스톤(4)과 브레이크 피스톤(5)이 왕복운동하는 실린더에 있어서,실린더 튜브(6)와 실린더헤드 커버(2) 및 실린더엔드 커버(3)에 공기 유입구(7)를 형성시켜 주고 피스톤(4)을 밀어주는 스프링(8)과 솔레노이드 밸브(1)로 부터 들어오는 공기압을 빼주고 브레이크 피스톤(5)과 실린더엔드 커버(3) 사이의 공기압을 빼주는 누름버튼(10)과 볼(9)로 구성된 것이다.According to a form of the present invention for achieving the above object, the piston (4) and between the cylinder tube (6) and the cylinder head cover (2) and the cylinder end cover (3) for fixing it according to the switching of the solenoid valve (1) In a cylinder in which the brake piston (5) reciprocates, a spring for forming an air inlet (7) in the cylinder tube (6), the cylinder head cover (2) and the cylinder end cover (3) and pushing the piston (4) (8) and the push button 10 and the ball 9 to release the air pressure coming from the solenoid valve (1) and to release the air pressure between the brake piston (5) and the cylinder end cover (3).

이와 같이 구성된 본 발명을 첨부도면과 함께 더욱 자세히 설명하면 다음과 같다.The present invention configured as described above will be described in more detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 실린더의 브레이크 제동상태 단면도로서 이를 설명하면 공기 유입구(7)를 따라 브레이크 피스톤(5)과 실린더엔드 커버(3) 사이로 공기가 공급되어 브레이크 피스톤(5)을 밀면 실린더튜브(6)내의 걸림턱(13)에 걸리게되고, 이때 스프링(8)의 힘에 의해 실린더(4)가 피스톤로드(11)와 고정되어 있어 피스톤로드(11)와 같이 피스톤(4)이 브레이크 피스톤(5)에 닿아 더 후진할 수 없게 된다.1 is a cross-sectional view of a brake braking state of a cylinder according to the present invention. When air is supplied between a brake piston 5 and a cylinder end cover 3 along an air inlet 7, the cylinder tube is pushed when the brake piston 5 is pushed. (6) is caught by the locking jaw 13, the cylinder 4 is fixed to the piston rod 11 by the force of the spring (8) so that the piston 4, like the piston rod 11, the brake piston It reaches (5) and can not back up further.

제3도는 본 발명에 따른 실린더의 브레이크 해제 상태 단면도로서 이를 설명하면 손잡이(12)의 레버(21)를 당겨 누름버튼(10)을 누르면 볼(9)이 위로 올라가고솔레노이드 밸브(1)에서 공기 유입구(7)를 통하여 들어오는 공기와 브레이크 피스톤(5)과 실린더엔드 커버(3) 사이의 공기가 누름버튼(10)과 부쉬(22)사이로 빠져나와 대기중으로 배출되게 된다.이때 스프링(8)에 의하여 피스톤(4)을 밀면 브레이크 피스톤(5)이 실린더엔드 커버(3)에 밀착되어지고 피스톤(4)과 고정된 피스톤 로드(11)가 완전 후진하게 된다. 이때 다시 전진시에는 솔레노이드 밸브(1)의 절환에 의해 실린더 튜브(6)의 공기 유입구(7)를 통하여 피스톤(4)과 브레이크 피스톤(5)사이에 유입되어 피스톤(4)과 피스톤 로드(11)가 앞으로 전진하게 된다.3 is a cross-sectional view of the brake release state of the cylinder according to the present invention. When the push button 10 is pulled out by pulling the lever 21 of the handle 12, the ball 9 rises up and the air inlet port of the solenoid valve 1 is shown. Air entering through (7) and air between the brake piston (5) and the cylinder end cover (3) exit between the pushbuttons (10) and the bush (22) and are discharged into the atmosphere. When the piston 4 is pushed, the brake piston 5 is brought into close contact with the cylinder end cover 3 and the piston 4 and the fixed piston rod 11 are completely retracted. At this time, when moving forward, the solenoid valve 1 switches between the piston 4 and the brake piston 5 through the air inlet 7 of the cylinder tube 6 to switch between the piston 4 and the piston rod 11. ) Will move forward.

제2도는 본 발명의 누름상태를 나타낸 단면도로서 제2(a)도는 브레이크장치의 제동상태이다. 이를 설명하면 볼(9)이 부쉬(22)와 밀착되어 공기는 빠져나오지 못하고 실린더엔드 커버(3)와 브레이크 피스톤(5)사이로 들어가 브레이크 피스톤(5)을 밀게 되고 제1도 상태가 된다.FIG. 2 is a sectional view showing the pressed state of the present invention, and FIG. 2 (a) is a braking state of the brake device. In this case, the ball 9 is in close contact with the bush 22 and air does not escape, but enters between the cylinder end cover 3 and the brake piston 5 to push the brake piston 5 to a first degree state.

제2(b)도는 브레이크 장치의 해제상태 단면도이다. 이를 설명하면 제3도와 같이 손잡이(12)의 레버(21)를 당겨 누름 버튼(10)을 누르면 볼(9)이 올라가면서 부쉬(22)와 볼(9)사이에 공간이 생겨 브레이크 피스톤(5)과 실린더엔드 커버(3) 사이의 공기와 솔레노이드 밸브(1)로 부터 들어오는 공기는(->)방향과 같이 대기중으로 빠져나오게 된다.2 (b) is a cross-sectional view of the released state of the brake device. To explain this, as shown in FIG. 3, when the lever 21 of the handle 12 is pushed and the push button 10 is pressed, a space is formed between the bush 22 and the ball 9 while the ball 9 is raised, thereby providing a brake piston 5. Air from the solenoid valve (1) and the air between the cylinder end cover (3) and the cylinder end cover (3) are released into the atmosphere in the direction of (->).

이상에서와 같이 솔레노이드 밸브 하나만을 사용하여 실린더내에서 피스톤을 정지 시킴으로서 안전사고를 방지 시키고, 간단한 버튼구조로 용접의 효율을 높이는 효과를 갖는다.As described above, by using only one solenoid valve to stop the piston in the cylinder to prevent safety accidents, it has the effect of increasing the efficiency of welding with a simple button structure.
