본 고안은 선출원한 84년 실용신안등록출원 제7271호의 "터릿선반의 공구 교환장치"에 있어서, 회전하는 터릿이 보다 정확한 작업 위치에서 정지하는 동시에 염가로 제작할 수 있도록 개량한 터릿 선반의 공구 교환장치"에 관한 것이다.The present invention is a tool changer of a turret lathe, which was improved in the 84 Utility Model Registration Application No.7271, "Turret Lathe Tool Changer", which allows the rotating turret to stop at a more accurate working position and at a lower cost. Is about.

선출원한 실용신안등록출원 제84-7271호의 "터릿선반의 공구 교환장치"에서는 제4도에 도시한 바와 같이, 공구 교환명령의 펄스가 콘트롤 박스(CB)로부터 인가되면 실린더 내의 피스콘 작동에 의해 터릿이 언클램프(Unclamp) 상태로 됨과 아울러 유압모우터(M)가 구동되어 동축의 주동기어(21)와 종동기어(22)가 회전하면서 중심축(23)도 같이 회전하게됨에 따라 터릿이 회전하다가 공구 교환 명령된 공구의 부위 약 12.5전에 터릿이 도달했을때 회전각 감지장치(24)에서 이를 즉시 감지하게 되고, 콘트롤 박스(CB)로부터는 감속시그날을 발하게 되어 모우터(M)의 유량이 자동 조절되면서 2r.p.m으로 감속회전되고 약 1.25전에 도달하였을 때는 정지 시그날이 콘트롤 박스(CB)로부터 나오게 되어 솔레노이드 밸브에 의하여 유압모우터 (M)에 유압공급이 차단되어 구동이 정지하게 됨과 아울러 터릿도 같이 정지하게 되는 바, 이때의 근접스위치(PS)는 종 동기어(22)의 내면에 돌설된 환편(25)과 근접되어 근접스위치(PS)가 온 되면서 원하는 공구 위치가 정확히 인덱싱(indexing)이 완료되었음을 콘트롤 박스(CB)에 전달하여 확인시키게 된다.In the utility tool registration application No. 84-7271, "Turret Lathe Tool Change Device", as shown in Fig. 4, when a pulse of a tool change command is applied from the control box CB, Turret is rotated as the turret is unclamped and the hydraulic motor M is driven to rotate the coaxial main gear 21 and the driven gear 22 while the central axis 23 is also rotated. Then, when the turret reaches about 12.5 days before the tool change command, the rotation angle detecting device 24 immediately detects it and emits a deceleration signal from the control box CB so that the flow rate of the motor M is increased. When the motor is decelerated and rotated to 2r.pm and reached about 1.25, the stop signal comes out of the control box (CB) and the hydraulic pressure is blocked by the solenoid valve to shut off the hydraulic motor (M). In addition, the turret also stops as well. At this time, the proximity switch PS is approached to the annular piece 25 protruding on the inner surface of the slave synchronism 22 and the desired switch position is turned on. The control box CB confirms that indexing is completed correctly.

그 다음으로는 실린더의 피스톤이 작동되어 터릿의 교합치와 중심축(23)의 교합치가 서로 클램프(Clamp)되어 터릿이 임의적으로 유동되지 않게 하므로서 공구의 교환작용이 완료 되도록한 것이었다.Next, the piston of the cylinder was operated so that the bite of the turret and the bite of the central shaft 23 were clamped with each other to prevent the turret from flowing arbitrarily, thereby completing the tool exchange.

그러나 상술된 "터릿 선반의 공구 교환장치"를 터릿선반에 적용하여 사용하였던바, 터릿이 정확한 작업 위치에 정지하는데 오동작이 발생하였다.However, when the above-mentioned "tool changer of the turret lathe" was applied to the turret lathe and used, a malfunction occurred when the turret stopped at the correct working position.

즉, 터릿이 회전하다가 공구 교환 명령된 공구의 부위 약12.5전에 회전각 감지장치(24)에서 감지됨으로서 콘트롤박스(CB)로부터 감속 명령을 받은 모우터(M)가 2r.m.p으로 감속 회전되고 약 1.25전에 도달하였을 때 콘트롤 박스(CB)의 정지 시그날에 의해 유압모우터(M)의 구동정지 되는 순간에 회전 관성력에 의해 1.25 더 회전된 다음 종동기어(22)가 정지하도록 작동될 때 종동기어(22)가 1.25보다 못미쳐 정지하거나, 지나쳐 정지하는 경우가 발생하므로서, 정밀한 절삭 가공이 이루어지지 않는 결점이 발생하였으며, 고가의 회전각 감지장치(24)를 사용하므로서 제품이 고가가되는 단점이 있었다. 따라서 터릿선반에서의 공구 교환시 발생되는 오동작을 제거함과 동시에 염가로 제작될 수 있는 공구 교환장치의 실현이 절실히 요망되었다.That is, the turret rotates and the motor M received the deceleration command from the control box CB is decelerated and rotated to 2r.mp by being detected by the rotation angle detecting device 24 about 12.5 before the tool change commanded part. When it reaches 1.25 before, the driven gear (when the driven gear 22 is operated to stop further by 1.25 by the rotational inertia force at the moment when the driving of the hydraulic motor M is stopped by the stop signal of the control box CB) 22) is less than 1.25, or stops too much, the defect that does not precise cutting process occurs, there was a disadvantage that the product is expensive by using an expensive rotation angle detection device 24 . Therefore, there is an urgent need for the realization of a tool changer that can be manufactured at a low cost while eliminating the malfunction occurring during the tool change in the turret lathe.

따라서, 본 고안의 목적은 상술한 문제들이 해결될 수 있는 새롭고 유용한 터릿선반의 공구 교환장치를 제공하는데 있는 것으로, 이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.Accordingly, an object of the present invention is to provide a new and useful tool changer of the turret lathe that can solve the above problems, which will be described in more detail with reference to the accompanying drawings.

즉, 본 고안은 도시한 바와 같이 터릿(1)이 중심축(2)에 의해 연동되도록 축설된 종동기어(3)와 치합되는 주동기어(4)가 유압모타(5)에 의해 구동되도록 착설된 몸체(6)에 계산용 근접스위치(7) 및 정위치용 근접스위치(7')가 설치되있으며, 상기 종동기어(3) 외측 주면에는 상호 이격된 계산용 도그(8)와 정위치용 도그(8')가 방사성으로 돌설되 있다.That is, the present invention is installed so that the main gear (4) meshing with the driven gear (3) arranged so that the turret (1) is interlocked by the central axis (2) as shown in the drawing is driven by the hydraulic motor (5) In the main body 6, the proximity switch 7 and the positional proximity switch 7 'are provided, and the calculation dog 8 and the position dog are spaced apart from each other on the outer main surface of the driven gear 3. 8 'is protruding radioactively.

상기 유압모우터(5)에는 정역방향 솔레노이드 밸브(SV1)(SV2)와 감속용 솔레노이드 밸브(SV3)가 연결되있다.The hydraulic motor 5 is connected to the forward and reverse solenoid valve SV 1 (SV 2 ) and the deceleration solenoid valve SV 3 .

도면중 미설명부호(9)는 유압탱크이며 (CB)는 콘트롤 박스이다.In the figure, reference numeral 9 denotes a hydraulic tank and CB denotes a control box.

이와 같이된 본 고안은 공구 교환 명령의 펄스가 콘트롤 박스(CB)로부터 인가되면 공지의 방법과 실린더 내로 유압이 유입되면서 피스톤이 작동되어 터릿(1)이 언클램프 상태로됨과 아울러, 정역방향 솔레노이드 밸브(SV1)(SV2)가 작동되어 유압모우터(5)를 구동시켜주어 이와 가동축의 주동기어(4)와 종동기어(3)가 회전하면서 중심축(2)도 같이 회전하게됨에 따라 터릿(1)이 회전을 하는데, 이때 계산용 근접스위치(7)는 회전하는 종동기어(3) 외측 주면에 돌설된 계산용 도그(8')를 감지하여 콘트롤 박스(CB)에 전달하게 된다.When the pulse of the tool change command is applied from the control box (CB), the present invention has a known method and the hydraulic pressure flows into the cylinder, and the piston is operated so that the turret 1 is unclamped and the forward and reverse solenoid valve (SV 1 ) (SV 2 ) is operated to drive the hydraulic motor (5) and the main shaft (4) and the driven gear (3) of the movable shaft and the center shaft (2) also rotates together as the turret (1) rotates, the calculation proximity switch 7 detects the calculation dog (8 ') protruding on the outer main surface of the driven driven gear (3) and transmits to the control box (CB).

즉, 공구교환이 명령된 공구에 해당하는 계산용 도그(8)에 도달하게되면 감속시그날이 콘트롤박스(CB)로부터 나오게되어 감속용 솔레노이드 밸브(SV3)를 작동시킴으로서 유압모우터(5)가 감속회전하는 도중에 정위치용 근접스위치(7')에 정위치용 도그(8')가 감지되면 정지 시그날이 콘트롤박스(CB)로부터 나오게되어 솔레노이드밸브(SV1)(SV2)에 의해서 유압모우터(5)에 유압공급이 차단되어 구동이 정지하게 됨과 아울러, 터릿(1)도 같이 정지하게 된다.That is, when the tool change reaches the calculation dog 8 corresponding to the commanded tool, the deceleration signal comes out of the control box CB to operate the deceleration solenoid valve SV 3 to operate the hydraulic motor 5. When the dog 8 'for exact position is detected by the proximity switch 7' for decelerating rotation, the stop signal comes out of the control box CB and the hydraulic pressure is moved by the solenoid valve SV 1 (SV 2 ). The hydraulic supply is interrupted to the turret 5 and the driving is stopped, and the turret 1 is also stopped.

다음에 실린더에 유압이 유입되어 피스톤이 원위치로 복귀되면서 다시 터릿(1)의 교합치와 중심축의 교합치가 서로 클램프되어 터릿(1)이 임의적으로 유동되지 않게 하므로서 공구의 교환 작용이 완료되는 것이다.Next, when the hydraulic pressure flows into the cylinder and the piston returns to its original position, the bite of the turret 1 and the bite of the central shaft are clamped to each other so that the turret 1 does not flow arbitrarily, thereby completing the tool exchange action.

본 고안에서의 특징적인 것은 회전하는 종동기어(3) 외측 주면에 돌설된 계산용 도그(8)를 계산용 근접스위치(7)가 계산하여 공구 교환이 명령된 공구에 해당하는 계산용 도그(8)를 계산용 근접스위치(7)가 감지하게 됨과 동시에 콘트롤박스(CB)로부터 감속 솔레노이드 밸브(SV3)를 작동토록하여 유압모우터(5)를 감속회전토록하는 도중에 정위치용 근접스위치(7')에 정위치용 도그(8')가 감지되는 순간, 유압모우터(5)를 정지되도록 한것에 특징이 있는 것으로, 오동작없이 정확하게 공구의 교환작용이 이루어질 수 있는 작용효과가 있는 것이다.A characteristic feature of the present invention is that the calculation dog 8 corresponding to the tool commanded to change the tool by calculating the calculation dog 8 protruding from the outer peripheral surface of the driven driven gear 3 is commanded to change the tool. ) Is detected by the proximity switch (7) for the calculation and the deceleration solenoid valve (SV 3 ) is operated from the control box (CB) to make the hydraulic motor (5) decelerate and rotate. At the moment when the dog 8 'for the correct position is detected, the hydraulic motor 5 is stopped, and there is an effect of exchanging the tool accurately without malfunction.

따라서 본 고안에 의하면 종동기어(3)에 계산용 도그(8)와 정위치용 도그(8')를 이격 돌설시켜 계산용 근접스위치(7)와 정위치용 근접스위치(7')에 의해 감지토록 하여 터릿(1)이 정확한 작업위치에서 정지되게한 효과외에도 종래와 같이 고가의 회전각 감지장치를 사용하지 않게되므로 제작원가가 저렴하고 보수가 용이한 효과가 있다.Therefore, according to the present invention, the calculation gear 8 and the positioning dog 8 'are spaced apart from the driven gear 3 to be sensed by the calculation proximity switch 7 and the positioning switch 7'. In addition to the effect that the turret (1) to stop at the correct working position so as not to use an expensive rotation angle detection device as in the prior art has a low production cost and easy maintenance.
