본 고안은 연삭기의 양센터 절삭유 공급장치에 대한 것이다.The present invention is directed to both center coolant feeder of the grinding machine.

종래에는 연삭작업중 공작물의 양센터를 지지하는 방법에 의해 연삭가공을 실시할 경우, 공작물을 잡아주는 양센터는 고정된 상태에서 공작물만 회전을 하게 되므로 공작물만 회전을 하게 되므로 회전을 하게 되므로 공작물의 센터 구멍과 주축대(WH)및 심압대(TS)에 고정된 양센터(S1)(S2)사이에 마찰이 발생되므로 마찰을 줄이기 위해 그리스를 소량으로 바른다음 연삭작업을 실시하는 것이 통례되어 있다.Conventionally, when grinding is performed by a method of supporting both centers of a workpiece during grinding, both centers that hold the workpiece rotate only the workpiece in a fixed state, so only the workpiece rotates, thereby rotating the workpiece. Since friction occurs between the center hole and both centers (S1) and (S2) fixed to the headstock (WH) and tailstock (TS), it is customary to apply a small amount of grease to grind to reduce friction. .

또한, 다음 작업대기증인 공작물에 사전에 그리스를 발라 준비해두는 방법을 이용하기도 하고 있으나, 이와같은 방법에 의하면 매공작물마다 그리스를 수작업으로 발라야 하므로 연속가공라인이나 자동화라인에서 양센터 지지작업인 경우에는 소요시간 과다 및 인원관리상의 어려운 문제점이 있었다.In addition, in some cases, grease should be applied to the next work-waiting work in advance, but according to this method, grease should be applied manually for each workpiece. There was an excessive time required and a difficult problem in personnel management.

본 고안은 상기와 같은 종래 양센터 지지방식에 의한 연삭작업시의 문제점을 감안하여 공작물의 회전시 양센터끝과 공작물 센터 구멍사이에 절삭유를 연속적으로 자동 공급하는 절삭유 공급장치를 제공함으로써 작업성과 생산성을 향상토록 안출한 것으로, 이를 첨부도면에 의거 상체히 설명하면 다음과 같다.The present invention, in view of the problems in the grinding operation by the conventional two-center support method as described above, by providing a coolant supply device for continuously supplying the coolant between the end of both center and the work center hole during the rotation of the workpiece workability and productivity In order to improve this, it is described as follows based on the accompanying drawings.

본 고안의 절삭유 공급장치는 주축대(WH)및 심압대(TS)의 양센터(S1)(S2)로 공자물(W)을 지지하여 연삭숫돌(G)에 의한 연삭작업을 실시하는 연삭기에 설치되는데 그 구성요소는;상기 연삭숫돌(G)에 절삭유를 공급하기 위해 설치된 절삭유 파이프(P)상에 설치되어 절삭유를 분배하는 분배밸브(3)와, 상기 분배밸브(3)와 연결 설치되고 절삭유의 유출량을 조절하는 볼밸브(l7)와, 상기 심압대(TS)의 센터(S2)를 감싸는 갭(15)에 고정설치되며 상기 볼밸브(17)에서 출력되는 절삭유 공급호스(10)가 연결된 밸브보디(1)와, 상기 주축대(WH)의 보디(16)에 고정 설치되며 상기 밸브보디(1)로부터 분기된 호스(10')가 연결된 밸브보디(11)와, 상기 두 밸브보디(1)(11)의 출력에 각각 연결되며 주축대(WH)및 심압대(TS)의 양센터(S1)(S2)에 근접 설치되는 쿨런트호스(5)(5')와 쿨런트 노즐(4)(4')및 밸브콕(6)(6')으로 구성된 절삭유 분사노즐세트(7)로 이루어져 연삭숫돌(G)에 의한 연삭작업시 상기 쿨런트노즐(4)(4')을 통하여 절삭유의 연속적인 공급이 실시되도록 한 것이다.The cutting oil supply device of the present invention supports a symmetrical object (W) to both centers (S1) and (S2) of the spindle (WH) and tailstock (TS) to grind the grinding work by the grinding wheel (G). The component is installed on the cutting oil pipe (P) installed to supply the cutting oil to the grinding wheel (G) and is connected to the distribution valve (3) and the distribution valve for distributing the cutting oil, The ball valve (l7) for adjusting the flow rate of the cutting oil and the fixed oil supply hose (10) is fixed to the gap 15 surrounding the center (S2) of the tail stock TS (TS) and output from the ball valve (17) A valve body 11 connected to the valve body 1 connected to the body 16 of the headstock WH and having a hose 10 'branched from the valve body 1 connected thereto, and the two valve bodies (1) (11) Coolant hoses (5) (5 ') and coolant nozzles, which are connected to the outputs of the headstock (WH) and tailstock (TS), respectively, and are installed in close proximity to both centers (S1) and (S2). (4) (4 ') And a coolant jet nozzle set (7) consisting of valve cocks (6) and (6 ') for continuous supply of coolant through the coolant nozzles (4) and (4') during the grinding operation by the grinding wheel (G). It is to be carried out.

도면중 미설명 부호;2는 스크류,8은 플레이트,9는 스크류이다.2 is a screw, 8 is a plate, 9 is a screw.

이와같은 본 고안의 작용효과를 설명하면, 기계전원을 '온'시킨 후 연삭작업을 실시하기 위해 싸이클스타트(Cycle start)버턴을 누르면 연삭숫돌(G)이 회전함과 동시에 절삭유가 절삭유 파이프(P)를 통하여 공급되게 된다.To explain the effect of the present invention, when the machine power is 'on' and the cycle start button is pressed to perform the grinding operation, the grinding wheel (G) rotates and the cutting oil is simultaneously applied to the cutting oil pipe (P). Will be supplied through

이때, 상기 절삭유파이프(P)의 중간에 설치된 분배밸브(3)를 통하여 절삭유가 분배 공급되며, 이 절삭유는 절삭유의 양을 조절하기 위해 설치된 볼밸브(17)에 의하여 그 양이 적절히 조절되어 출력되게 된다. 이와같이 볼밸브(17)를 통해 출력된 절삭유는 다시 호스(10)를 통하여 심압대(TS)측에 설치된 밸브보디(1)내로 유입되며 여기서 절삭유는 다시 2가닥으로 분리된다. 즉, 한가닥은 심압대(TS)측 센터(S2)로 공급되는데 쿨런트호스(5')를 거쳐 끝이 뾰족한 노즐(4)을 통하여 센터(S2)끝부분으로 분사된다. 이때에도 절삭유의 분사량을 조절하려면 쿨런트호스(5')에 설치된 밸브콕(6')을 이용하면 된다.At this time, the cutting oil is distributed and supplied through the distribution valve (3) installed in the middle of the cutting oil pipe (P), the amount of the cutting oil is properly adjusted by the ball valve (17) installed to adjust the amount of cutting oil is output Will be. Thus, the cutting oil output through the ball valve 17 is introduced into the valve body 1 installed on the tailstock TS side again through the hose 10, where the cutting oil is separated into two strands again. That is, one strand is supplied to the tailstock (TS) side center (S2) is injected to the end of the center (S2) through the coolant hose (5 ') through the pointed nozzle (4). At this time, in order to adjust the injection amount of cutting oil, the valve cock 6 'provided in the coolant hose 5' may be used.

그리고 나머지 한가닥은 마시 호스(10')를 통하여 공작무 주축대(WH)측으로 공급이 되는데 분기출력된 절삭유는 호스(10')를 통해 주축대 보디(16)에 부착된 밸브보디(11)내로 유입된다.And the other strand is supplied to the work headstock (WH) side through the drinking hose (10 ') the branched output cutting oil into the valve body (11) attached to the headstock body 16 through the hose (10') Inflow.

밸브보디(11)로 유입된 절삭유는 다시 절삭유 분사노즐세트(7)를 구성하는 분사량 조절용 밸브콕(6)과 호스(5)를 거쳐 호스끝에 설치된 노즐(4)을 통해 공작물을 물고 있는 센터(S1)에 절삭유를 공급하게 된다.The cutting oil introduced into the valve body 11 is again centered by the workpiece through the nozzle 4 installed at the end of the hose via the valve amount 6 and the hose 5 for adjusting the injection oil nozzles 7. Cutting oil is supplied to S1).

절삭유가 흐르는 호스는 필요방향으로의 임의조절이 가능하며, 특히 심압대(TS)측 밸브보디(1)는 심압대캡(15)에 조립되어 있는 관계로 연삭작업이 끝나고 연삭숫돌(G)이 후퇴하면 절삭유가 차단됨과 동시에 심압대의 센터(S2)가 후퇴하게 되는데, 이때 같이 후퇴이동을 하게 되어 공작물의 길이가 변하더라도 상관없이 그사용이 가능하게 되는 것이다.The hose flowing with cutting oil can be arbitrarily adjusted in the required direction. Especially, the tailstock (TS) side valve body (1) is assembled to the tailstock cap (15), so the grinding work is finished and the grinding wheel (G) is retracted. If the coolant is cut off at the same time the center of the tailstock (S2) is retracted, this is to move back as it is possible to use regardless of the change in the length of the workpiece.

이와같이 본 고안은 종래 수동방식을 지양하고 양센터측의 절삭유 분사노즐세트를 구비시켜 연삭작업시 절삭유의 연속공급이 자동으로 이루어지도록 하여 센터부의 마모방지와 마찰열을 식혀주도록 함으로써 품질향상(가공정도향상)및 작업성 향상을 가져올 수 있게 되는 것이다.As such, the present invention avoids the conventional manual method and is equipped with a set of coolant injection nozzles at both centers so that the continuous supply of coolant is automatically performed during grinding work, thereby preventing the wear of the center part and cooling the frictional heat to improve the quality (process improvement. And workability will be improved.
