본 고안은 압축공기를 이용하여 쇼트볼(shot ball)을 피가공금속표면에 강하게 분사타접시키므로서 금속표면에 생성된 녹(綠)을 비롯한 각종 불순물을제거 및 정화하는 금속표면연마가공기의 원격조정 장치에 관한 것이다.The present invention remotely controls the surface grinding machine to remove and purify various impurities such as rust generated on the metal surface by spraying and contacting the shot ball to the metal surface to be processed by using compressed air. Relates to a device.
일반적인 종래의 쇼트볼 연마가공기는 압축공기의 압출을 제어하는 압축공기제어밸브와 쇼트볼을 전기한 압축공기에 혼입시키는 쇼트볼제어밸브의 결합으로 이루어지는데, 작업시에는 이들 양 제어밸브로부터 길게 관출한 고압호우스의 선단A conventional conventional ball ball grinding machine consists of a combination of a compressed air control valve for controlling the compression of compressed air and a shot ball control valve for mixing the shot ball into compressed air. Leading high pressure hose
그러나 종래에는 쇼트볼의 분사와 정지를 조정하는 구동장치에 작업장소인 고압호우스의 노즐 부분에 설치되지 않고 작업장소와는 원거리인 쇼트볼 제어밸브와 압축공기제어밸브 자체에 설치되어 있어서 작업시 노즐을 잡고 작업을 수행하는 작업자와는 별도로 작업자의 신호에 따라 쇼트볼의 분사를 제어시키는 조작자가 쇼트볼 가공기의 인접부에 항상 대기하여 있어샤 되므로 불필요한 인력이 소요되고 작업능률이 매우 저조하였으며, 특히 조선공업분야와 같이 칸막이 선실이 많은 피가공물체내에서 작업을 수행함에 있어서는 작업자의 임의로운 판단에 의하여 쇼트볼의 분사 또는 정지를 임의로 조정시키기가 곤란하였다.However, in the prior art, it is not installed in the nozzle part of the high pressure hose, which is a working place, in the driving device for adjusting the spraying and stopping of the shot ball. Apart from the operator who grabs the nozzle, the operator who controls the shot ball's injection is always waiting in the adjacent part of the shot ball machine according to the operator's signal, so it takes unnecessary manpower and the work efficiency is very low. In particular, when performing work in a workpiece with a large number of compartment cabins, such as in the shipbuilding industry, it is difficult to arbitrarily adjust the spraying or stopping of the shot ball at the discretion of the operator.
본 고안은 이러한 폐단을 시정 보완하여 고압호우스의 노즐부분에 있는 작업자가 쇼트볼 가공기와는 원거리에 떨어진 장소에서도 임의로 작업을 진행시키거나 정지시킬 수 있는 매우 편리한 원격조정장치를 안출하여 쇼트볼 가공기의 작업능률을 종래보다 크게 향상시킨 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention compensates for these closed ends and creates a very convenient remote control device that allows the operator at the nozzle part of the high pressure hose to move or stop the work arbitrarily even at a place remote from the shortball machine. The work efficiency of the greatly improved than before, described in detail based on the accompanying drawings as follows.
제1도의 약해도와 같이 통상의 압축기(12)로부터 도출한 압출관(5')에 압축공기제어밸브(4)와 쇼트볼제어밸브(1)를 개재시켜 이들 제어밸브(1)(4)로부터 관출한 고압호우스(5)의 선단에 노즐(5'')을 착설하여 쇼트볼 제어밸브(1)의 탱크(2)내As shown in FIG. 1, the compressed air control valve 4 and the short ball control valve 1 are interposed from the control valves 1 and 4 in the extrusion pipe 5 'drawn from the conventional compressor 12. In the tank 2 of the short ball control valve 1, a nozzle 5 "
도면중 미설명 부호 22는 쇼트볼(3)이 압축공기제어밸브(4)로 역류하는 것을 방지시키는 밸브관(29)내의 역지밸브이고, 28,28'는 유통공(26)(26')의 볼밸브이다.In the figure, reference numeral 22 denotes a check valve in the valve tube 29 which prevents the short ball 3 from flowing back into the compressed air control valve 4, and 28 and 28 'are flow holes 26 and 26'. Ball valve.
이상과 같이 된 본 고안은 압축기(12)의 압축공기가 압출관(5')을 거쳐 압축According to the present invention as described above, the compressed air of the compressor 12 is compressed through the extrusion pipe 5 '.
이때 볼밸브(28)는 폐쇄 상태로 되나 타측 볼밸브(28')는 개방되어 유통공(26') 및 연결관(27)을 통해 압축공기제어밸브(4)의 가압실(23')과 쇼트볼제어밸브(1)의 가압실(16)로 압축공기는 각각 유입된다.At this time, the ball valve 28 is in a closed state, but the other ball valve 28 'is opened, and the pressurized chamber 23' of the compressed air control valve 4 and the through-hole 26 'and the connecting pipe 27 are opened. Compressed air flows into the pressurizing chamber 16 of the shot ball control valve 1, respectively.
따라서 압축공기제어밸브(4)내에 설치된 다이어프레임(24)은 하측유입구(20)를 통해 상향으로 가압되는 공기압과 가압실(23)내로 유입되어 가해지는 공기압으로 인한 평형 상태가 이루어지나 다이어프레임(24)의 상부는 스프링(25)이 하향으Therefore, the diaphragm 24 installed in the compressed air control valve 4 has an equilibrium state due to the air pressure pressurized upwardly through the lower inlet 20 and the air pressure introduced into the pressurizing chamber 23. The upper portion of the 24 is the spring 25 downwards
또한 이와 동시에 쇼트볼제어밸브(1)의 가압실(16)내에 유입된 공기는 가압판(17)을 아래로 눌러 고무제로된 신축밸브(18)가 차단된 상태로 되어 고압호우스(5)의 노즐(5'')을 통한 쇼트볼(3)의 분사가 중지되어 연마작업은 일시 정지되는 상태로 된다.At the same time, the air flowing into the pressure chamber 16 of the short ball control valve 1 presses the pressure plate 17 downward so that the rubber expansion and contraction valve 18 is blocked, and thus the high pressure hose 5 The spraying of the shot ball 3 through the nozzle 5 '' is stopped and the polishing operation is temporarily stopped.
이러한 상태에서 쇼트볼 연마작업을 수행코져 할 때 원격조절밸브(A)의 압동판(11)을 아래로 눌러 제1도 C 위치로 잡고 있으면 이의 습동구(9)는 변좌(8)내로 하강하여 유통공(6')(7')에 연통되었던 ??자형 유통공(9'')은 어긋난 상태로 되고 대신 ??자형 유통공(9')이 고정대(8)의 배기공(8'')에 일치되는 것이며 이로 인해 연결관(7)으로 들어오는 고압공기는 제3a도 및 제4a도와 같이 차폐되는 상태로 되므로 쇼트볼제어밸브(1)의 가압실(16)과 압축공기제어밸브(4)의 가압실(23')내로는 공기가 유입되지 않아 압력이 소멸된다.In this state, when performing the shot ball grinding operation, if the pressure plate 11 of the remote control valve (A) is pushed down and held in the first position C position, the sliding holes (9) thereof are lowered into the toilet seat (8). ?? distribution hole 9 '', which has been in communication with the distribution hole 6 ', 7', is displaced, and the ??-shaped distribution hole 9 'is replaced by the exhaust hole 8' 'of the fixing stand 8; And high pressure air coming into the connecting pipe 7 is shielded as shown in FIGS. 3a and 4a, and thus the pressurized chamber 16 and the compressed air control valve 4 of the short ball control valve 1 Air does not flow into the pressurizing chamber 23 'of the () and thus the pressure disappears.
따라서 쇼트볼제어밸브(1)의 가압실(16)내에 유입된 공기는 연결관(27)과 압축공기제어밸브(4)의 유통공(26')을 거쳐 역류하여 가압실(23')내의 공기와 합류되고 다시 볼밸브(28)을 개방시키면서 연결관(6) 및 원격조절밸브(A)의 ??자형 유통공(9')을 통해 밖으로 배기되어 버리므로서 제4a도와 같이 압축공기 제어밸브(4)의 다이어프레임(24)은 밸브관(19)의 유입구(20)로 압송되는 압축공기의 강압력에 의해 개방되어 배출구(21)를 통해 쇼트볼 제어밸브(1)의 밸브관(13)으로 압축공기가 압송되고 이와 동시에 쇼트볼제어밸브(1)의 신축밸브(18) 또한 가압실(16)내의 공Therefore, the air flowing into the pressurizing chamber 16 of the short ball control valve 1 flows back through the connection pipe 27 and the distribution hole 26 'of the compressed air control valve 4, Compressed air is controlled as shown in FIG. 4A by joining the air and exhausting it out through the? -Shaped distribution hole 9 'of the connecting pipe 6 and the remote control valve A while opening the ball valve 28 again. The diaphragm 24 of the valve 4 is opened by the coercive pressure of the compressed air that is pushed into the inlet 20 of the valve tube 19, and the valve tube of the shot ball control valve 1 through the outlet 21 ( 13) the compressed air is compressed and at the same time the expansion valve 18 of the short ball control valve 1
그리고 원격조절밸브(A)의 압동판(11)으로부터 손을 떼면 제1도와 같이 스프링(10)의 탄성에 의해 압동판(11)이 B위치로 복귀되고 습동구(9)가 상승되어 전술한 바와 같은 작업정지 상태로 되돌아간다.When the hand is released from the pressure plate 11 of the remote control valve A, the pressure plate 11 is returned to the B position by the elasticity of the spring 10, as shown in FIG. Return to the stopped state as shown.
따라서 본 고안에 의하면 쇼트볼가공작업을 행함에 있어서, 고압호우스(5)의 노즐부(5'')를 잡고 작업을 행하는 작업자가 원거리에서도 압축공기제어밸브(4)와 쇼트볼제어밸브(1)을 스스로 조정하여 임의로 작업개시와 중단을 시킬 수 있으므로 작업능률이 종래 보다 더욱 향상되고 압축공기제어밸브(4)와 쇼트볼제어밸브(1)를 조정하는 보조자를 별도로 필요하였던 종래와 같은 이중인력의 낭비가 없어지게 되는 효과를 갖는다.Therefore, according to the present invention, in carrying out the shot ball processing operation, the operator who holds the nozzle portion 5 '' of the high pressure hose 5 and performs the operation, the compressed air control valve 4 and the short ball control valve ( 1) Self-adjustment can be used to start and stop work arbitrarily. Therefore, the work efficiency is further improved than before, and the same dual pressure as in the prior art, in which an assistant to adjust the compressed air control valve 4 and the short ball control valve 1 was needed separately. The waste of manpower is eliminated.
