본 고안은 특히 소형 선반의 심압대에 있어서, 공작물의 센터를 지지할 필요가 없는 절삭 작업을 할 때에는 심압대가 공구대에 간섭을 일으키지 않고, 공구대의 작업 범위를 넓게 활용 할 수 있도록 심압대 몸체를 일측방향으로 일정 각도 회전시킬 수 있는 회전용 심압대에 관한 것이다.In particular, in the tailstock of small lathes, the tailstock body is designed so that the tailstock does not interfere with the tool post and can utilize a wide range of tool posts when the cutting operation does not need to support the center of the workpiece. It relates to a rotating tailstock that can be rotated at an angle in one direction.

주지하다시피, 주로 척작업만으로 작업을 하는 소형 선반에서 심압대의 합리적인 설치는 짧은 공작물을 가공할 때, 즉 센터 지지 작업이 필요 없을 때에는 공구대의 간섭을 일으키지 않는 범위 내에서 심압대를 회전이동시켜 놓으므로서 공구대의 작업 반경을 넓게 활용 할 수 있도록 구성된 것이다.As is well known, the reasonable installation of tail stock on small lathes, mainly with chucking, allows the tailstock to be rotated to the extent that it does not interfere with the tool when machining short workpieces, i.e. when center support is not required. Therefore, it is configured to make wide use of working radius of tool bar.

종래에는 척과 심압축의 센터가 일치하는 위치에 심압대를 고정 설치하였다.Conventionally, the tail stock was fixed at a position where the center of the chuck and the tail compression coincided.

이것은 공작물의 흔들림을 방지해 주는 심압대의 기본 기능은 수행되지만, 특히 척 작업 위주로 작업이 진행되는 소형 선반에서의 심압대는 공구대와의 간섭을 피할 수 없는 문제점이 있었다.This is to perform the basic function of the tailstock to prevent the shaking of the workpiece, especially the tailstock in the small lathe work is carried out mainly chuck work has a problem that can not avoid the interference with the tool bar.

따라서, 본 고안은 종래의 문제점을 해결하기 위하여 안출된 것으로, 선반의 베드를 심압대의 중심으로부터 일정 거리의 위치에 설치하고, 심압대의 베이스 내부의 축이 회전할 수 있도록 유압회로를 구성 하여서 되는 회전용 심압대를 제공하고저 함에 고안의 목적이 있는 것이다.Therefore, the present invention was devised to solve the conventional problems, and is provided by installing a bed of a shelf at a certain distance from the center of the tail stock, and configuring the hydraulic circuit so that the shaft inside the base of the tail stock can rotate. Its purpose is to provide a dedicated tailstock.

이하, 본 고안의 바람직한 구성과 작용및 효과등을 첨부된 도면과 관련하여 상세히 기술하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the preferred configuration, operation and effects of the present invention in detail as follows.

첨부도면 제3도에 도시된 바와같이 본 고안에 의한 심압대 베이스 부의 내부 구성과 유압회로의 구성을 살펴보면, 심압대의 회전몸체(2)는 심압대 베이스(14)의 내부에 설치된 축(S1)의 일측과 연결되며, 상기 회전몸체(2)의 회전 운동을 구속, 해제하는 클램프 거플링(3)은 밸브(V1)와 연결된 클램프 실린더(4)의 진퇴 작동으로 이루어지며, 상기 축(S1)의 타축에는 기어(10)를 설치하여, 일측에 기어(5)와 피니언(6)을 형성한 또다른 축(S2)과 연결되며, 첨부도면 제1도에 도시된 바와같이 랙크(7)를 상, 하 운동시킬수 있도록 피스톤(9)을 내장한 실린더(8)에는 밸브(V2)의 유로(C)(D)를 각각 연결하고, 실린더(8)와 밸브(V2)사이에는 체크밸브(CV1)(CV2)를 연결 구성하여 됨을 특징으로 하는 회전심압대이다.Referring to the internal configuration of the tail stock base portion and the hydraulic circuit as shown in Figure 3 attached to the present invention, the rotating body 2 of the tail stock is installed shaft (S1) inside the tail stock base 14 Is connected to one side of, the clamping guffling (3) for restraining, releasing the rotational movement of the rotary body (2) is made by the retraction operation of the clamp cylinder (4) connected to the valve (V1), the shaft (S1) The other shaft of the gear 10 is installed, connected to another shaft (S2) formed a gear (5) and pinion (6) on one side, as shown in Figure 1 of the accompanying drawings, rack 7 Flow paths C and D of the valve V 2 are respectively connected to the cylinder 8 having the piston 9 in such a manner as to move up and down, and a check valve between the cylinder 8 and the valve V2. CV1) (CV2) is a rotating tailstock characterized in that the configuration.

상기와 같은 본 고안의 작용을 설명하면, 첨부도면 제2도에서 선반척외 중심과 심압대 중심(11)이 일치한 스웡인(Swing-in)(16)상태에서 센터를 지지하여 작업하게 되고, 이렇게 공작물의 센터가 지지된 상태에서 센터의 지지 작업이 필요 없는 스윙아읏(Swing-out)(12)상태로 전환하고자 할때는 밸브(V1)를 b1위치로 절환하면. 압유는 유로(A)를 따라 클램프 실린더(4)로 유입되는 동시에 유로(B)를 통하여 탱그(T)로 귀환하면서 공작물의 센터를 지지하도록 회전몸체(2)의 움직임을 방지하는 클램프 커플링(3)이 해제되면서 회전몸체(2)의 구속이 해제된다.Referring to the operation of the present invention as described above, in the accompanying drawings, the center of the shelf chuck and the tailstock center (11) in the state of the swing-in (Swing-in) 16 is to work to support the center, If you switch the valve (V1) to the b 1 position when you want to switch to the swing-out (12) without the support of the center, the center of the workpiece is supported. The pressure oil flows into the clamp cylinder 4 along the flow path A and at the same time returns to the tank T through the flow path B while preventing the movement of the rotating body 2 to support the center of the workpiece. 3) is released and the restraint of the rotating body (2) is released.

이때, 밸브(V2)도 b2위치로 절환되어 압유는 체크밸브(CV1)와 유로(C)를 거쳐 실린더(8)로 유입되면서 피스톤(9)과 랙크(7)가 하측 방향으로 작동이 이루어지며, 유압 입구(P)에서 유입되는 유압에 의하여 체크밸브(CV2)가 열리게 되어 실린더(8)의 압유는 탱크(T)로 귀환 한다.At this time, the valve V2 is also switched to the b 2 position so that the hydraulic oil flows into the cylinder 8 through the check valve CV1 and the flow path C, and the piston 9 and the rack 7 operate downward. The check valve CV2 is opened by the hydraulic pressure flowing from the hydraulic inlet P, and the pressure oil of the cylinder 8 is returned to the tank T.

이러한 상태에서 피니언(6)은 축(S2)과 기어(5)를 우측으로 회전시키면서 상기 기어(5)와 맞물린 기어(10)를 좌측으로 회전시킨다.In this state, the pinion 6 rotates the gear 10 meshed with the gear 5 to the left while rotating the shaft S2 and the gear 5 to the right.

따라서 축(S1)과 연결된 회전몸체(2)는 축(S1)을 중심으로 스웡아웃(12)상태가 되는 회전이 시작된다.Therefore, the rotation body 2 connected to the shaft S1 is started to rotate to the swimout 12 state around the shaft S1.

상기 회전동작이 완료되면, 밸브(V1)는 a1위치로 절환되어 압유는 유로(B)를 따라 클램핑 실린더(4)로 유입되면서 커플링(3)을 작동시켜 회전몸체(2)를 클램핑하는 스윙아웃(Swing-out)(12)상태가 된다.When the rotation operation is completed, the valve (V1) is switched to the a 1 position so that the hydraulic oil flows into the clamping cylinder (4) along the flow path (B) to operate the coupling (3) to clamp the rotating body (2) The swing-out state 12 is entered.

그러면, 다시 스웡아웃(12) 상태에서 스윙인(16)상태로 작동시키는 과정을 살펴보면, 상기와 같이 밸브(V1)를 bl위치로 절환하면 회전몸체(2)를 구속하고 있던 커플링(3)이 해제되고, 밸브(V2)를 a2위치로 절환하여 압유는 유로(D)를 따라 실린더(8)로 유입되면서 피스톤(9)과 랙크(7)를 상측방향으로 작동시키면서 상기의 동작이 역으로 진행되어 스윙인(16)상태가 되는 것이다.Then, looking at the process of operating in the swing-in (16) state from the scoop out (12) again, when the valve (V1) is switched to the position b l as described above, the coupling (3) restraining the rotating body (2) ) is cleared, by switching the valve (V2) to a 2 position pressure oil has a piston 9 and the operation of the while operating in the upward direction rack 7 while flowing into the cylinder (8) along the flow path (D) In reverse, the swing-in state 16 is obtained.

첨부도면중 미설명 부호 V3은 심압축(1)을 작동시키는 밸브이다.In the accompanying drawings, reference numeral V3 denotes a valve for operating the cardiac compression 1.

이상과 같은 본 고안에 의하면, 심압축(1)을 회전시키므로서 공구대(17)의 작업반경을 넓게 활용할 수 있으며, 공구대와의 간섭을 일으키는 등의 작동상 장애요인을 해소할수 있는 효과가 있다.According to the present invention as described above, by rotating the cardiac compression (1) can be widely utilized the working radius of the tool bar 17, the effect that can eliminate the obstacles in operation such as causing interference with the tool bar have.
