본 고안은 공작기계의 로터리 테이블 클램프장치에 관한 것으로, 특히 회전하여 일정각도로 테이블을 위치시킨후 클램프하여 가공을 실시하는 공작기계의 로터리 테이블 클램프장치에 관한 것이다.The present invention relates to a rotary table clamp device of a machine tool, and more particularly, to a rotary table clamp device of a machine tool that rotates and positions the table at a predetermined angle to perform machining by clamping.
일반적인 수평형 머시닝센터나 보링머신과 같은 공작기계에는 공작물의 가공을 위해 제1도에서와 같이, 베이스(100)상에 형성된 회전축(110)에 로터리 테이블(200)이 회전가능하게 결합되어, 이 로터리 테이블(200)에 공작물을 위치시켜, 상기 베이스(100)에 대해 로터리 테이블(200)을 단속적으로 회전 또는 고정시키면서 공작물의 가공작업을 하도록 하는데, 이처럼 공작물을 고정하고 있는 로터리 테이블을 베이스에 대해 고정시키는 경우 클램프장치를 사용하고 있다.In general machine tools such as horizontal machining centers and boring machines, the rotary table 200 is rotatably coupled to a rotating shaft 110 formed on the base 100, as shown in FIG. The workpiece is placed on the rotary table 200, and the workpiece is processed while the rotary table 200 is intermittently rotated or fixed with respect to the base 100. Thus, the rotary table holding the workpiece is fixed to the base. In case of fixing, clamping device is used.
이러한 종래의 클램프장치는 로터리테이블(200)의 저면둘레의 다수개소에 설치되는 것으로, 제2도에서와 같이 턱(11)을 갖는 실린더(10)를 베이스(100)에 설치하고, 이 실린더(10) 내부에는 중앙에 클램프 피스톤(20)을 삽입관통시킨 상,하 피스톤(22,24)을 결합하되, 상피스톤(22) 저부에는 홈(21)을 가공하고, 상기 클램프 피스톤(20)의 상부는 너트 및 볼트(23,24)로 체결된 테두리(25)가Such a conventional clamping device is installed at a number of places around the bottom of the rotary table 200, and as shown in FIG. 2, a cylinder 10 having a jaw 11 is installed on the base 100, and the cylinder ( 10) Inside the upper and lower pistons 22, 24 through which the clamp piston 20 is inserted and coupled to the center, but the groove 21 is machined in the bottom of the upper piston 22, and the clamp piston 20 The upper part has an edge 25 fastened with nuts and bolts 23 and 24.
로터리 테이블(200) 저면에 형성된 설치홈(205)에 내설되어 걸리도록 하고, 이 테두리(25)와 상피스톤 사이에 스프링(S1)이 탄력있게 설치되고, 하피스톤(24)과 로터리 베이스(100) 사이에도 스프링받이(26)가 개재되어 스프링(S2)을 탄력있게 설치하며, 클램프 피스톤(20)의 하부는 너트(27)가 체결되고, 이 너트로부터의 유압공급에 따른 유로(28)가 상기 피스톤(20)에 형성되어 상, 하 피스톤 사이로 압유가 공급되게 된다.이러한 종래 클램핑장치는 압유의 공급에 따라 클램프 피스톤(20)의 유로(28)를 통해 홈(21)으로 압유가 충진되므로써 상,하 피스톤(22,24)이 각각 상하로 벌어지면서 로터리 테이블(200)저면을 밀고 클램프 피스톤(20)을 하부로 당겨 주는 힘으로 클램프 피스톤(20)의 테두리(25)가 설치홈(205)의 단턱부를 하부로 당겨줌으로써 로터리 테이블(200)을 베이스(100)에 대해 클램핑하게 된다.It is installed in the mounting groove 205 formed on the bottom of the rotary table 200, the spring (S1) is elastically installed between the rim 25 and the epithelium, the harpy stone 24 and the rotary base 100 Spring (26) is interposed between the spring bearing (26) and elastically install the spring (S2), the lower portion of the clamp piston 20, the nut 27 is fastened, the flow path 28 according to the hydraulic supply from the nut is The piston 20 is formed in the piston 20 so that the hydraulic oil is supplied between the upper and lower pistons. In the conventional clamping device, the hydraulic oil is filled into the groove 21 through the flow path 28 of the clamp piston 20 in accordance with the supply of the hydraulic oil. The upper and lower pistons 22 and 24 are opened up and down, respectively, pushing the bottom of the rotary table 200 and pulling the clamp piston 20 downward, so that the edge 25 of the clamp piston 20 is installed in the groove 205. Bay by rotating the stepped portion of the table below It is clamped about 100.
그러나, 이러한 종래의 클램핑장치는 그 부품수가 많고, 이에 따른 가공 및 조립공수가 과다하며 제작 및 조립공차가 클 수밖에 없어 유량의 지연배출로 인해 클램핑력이 약하고, 그 시간이 지연되는 문제점과 부품 상호간의 트러블이 발생하는 등 클램프의 신뢰도가 저하되는 문제점이 있다.However, such a conventional clamping device has a large number of parts, and there is an excessive number of machining and assembly operations, and a large manufacturing and assembling tolerance. Therefore, the clamping force is weak due to delayed discharge of flow rate, and the time is delayed. There is a problem that the reliability of the clamp is lowered, such as a trouble occurs.
따라서 본 고안은 이상과 같은 문제점을 감안하여 창안한 것으로, 본 고안의 목적은 부품수가 적어 조립공차의 관리 및 가공이 용이하고 신뢰가 높은 클램핑작용을 이루는 클램핌장치를 제공함에 있다.Therefore, the present invention was devised in view of the above problems, and an object of the present invention is to provide a clamping device that achieves a high clamping action with high reliability and easy handling and processing of assembly tolerances.
상기 목적을 달성하기 위해 본 고안은 로터리 베이스의 둘레에 볼트로 체결 고정되는 커버링을 가지고, 이 커버링으로 형성된 내부공간의 내측에 실링되는 중공 실린더형 클램프링과, 그 하부에 리턴피스를 두되 로터리 테이블에 고정설치되어 외측을 향하여 돌출설치된 클램프피스로 개재되고, 상기 리턴피스 외측 저부와 로터리 베이스사이에는 스프링 관통설치한 스프링 가이드를 구비하며, 클램프링의 소정위치 양측으로 유압포트가 설치된다.In order to achieve the above object, the present invention has a covering that is bolted and fixed around a rotary base, and a hollow cylindrical clamp ring sealed inside of the inner space formed by the covering, and a return piece beneath the rotary table. It is interposed with a clamp piece that is fixed to the protruding toward the outside, and is provided with a spring guide installed through the spring between the bottom of the return piece and the rotary base, the hydraulic port is provided on both sides of the predetermined position of the clamp ring.
이하에서 이를 첨부도면에 의해 상세히 설명하기로 한다.This will be described in detail with reference to the accompanying drawings.
제3도에서와 같이 공작기계의 로터리 테이블 클램프장치를 형성함에 있어서, 링형상 커버링(1)이 로터리 베이스(2) 상면에 내부공간을 형성하면서 볼트(B)로 체결고정되고, 그 내부공간에는 이 커버링 내측벽과 실링결합되는 중공실린더형 클램프링(3)이 설치되고, 그 저부에는 로터리 데이블(4)에 고정되면서 외측을 향하여 돌출설치된 클램프피스(5)가 로터리 베이스(2)에 면접촉되고, 상기 클램프 피스(5)와 클램프링(3)과의 사이에 리턴피스(6)가 끼워 설치되며, 이 리턴피스(6) 외측 저부에는 가이드홈(61)을 형성하고, 상기 대응위치의 로터리 베이스(2) 둘레에는 스프링(S)을 관통설치한 스프링 가이드(G)를 설치할 홈(H)을 형성하되, 상기 스프링 가이드(G)가 리턴피스(6)의 가이드홈(61)에 삽입되어 승강안내되게 설치된다.In forming the rotary table clamp device of the machine tool as shown in FIG. 3, the ring-shaped covering 1 is fastened and fastened with bolts B, forming an inner space on the upper surface of the rotary base 2, and in the inner space thereof. The hollow cylinder-type clamping ring (3) sealingly coupled to the covering inner wall is provided, and at the bottom thereof, a clamp piece (5) which is fixed to the rotary table (4) and protrudes outward is face-contacted to the rotary base (2). And a return piece 6 is inserted between the clamp piece 5 and the clamp ring 3, and a guide groove 61 is formed at an outer bottom of the return piece 6. A groove (H) is formed around the rotary base (2) to install a spring guide (G) installed through the spring (S), and the spring guide (G) is inserted into the guide groove (61) of the return piece (6). The elevating guide is installed.
그리고 상기 클램프링(3)의 중공부위로는 커버링의 양측으로부터 유압포트(P)가 연결 구성된다.And the hydraulic port (P) is connected to the hollow portion of the clamp ring (3) from both sides of the covering.
이상과 같이 구성된 본 고안의 작용효과를 살펴보면 제3도 및 제4도에서와 같이 유압포트(P)로 압유가 공급되면, 클램프링(3) 부위의 내부에 유압이 작용하여 클램프링(3)이 상,하 방향으로 벌어진다. 이 벌어지는 힘이 리턴스프링(S)을 압축시키면서 리턴피스(6)를 밀어주고, 여기에 밀접해 있는 클램프피스(5)가 힘을 받아 로터리 베이스(2)와 접촉을 하면서 마찰을 일으키고, 이러한 마찰력에 의해서 클램프피스(5)와 연계 고정된 로터리 테이블(4)이 로터리 베이스(2)에 대해 고정된다.Looking at the effect of the present invention configured as described above when the hydraulic oil is supplied to the hydraulic port (P) as shown in Figures 3 and 4, the hydraulic pressure acts on the inside of the clamp ring (3) clamping ring (3) This spreads up and down. This unfolding force pushes the return piece 6 while compressing the return spring S, and the clamp piece 5 in close contact with this causes the friction while being brought into contact with the rotary base 2, and this friction force By means of the rotary table 4 is fixed relative to the rotary base (2) fixed in conjunction with the clamp piece (5).
한편, 유압포트(P)로 공급되는 압유를 차단하면 클램프 동작시에 압축되었던 리턴스프링(S)이 복원되면서 리턴피스(6)를 위로 밀어주기 때문에 클램프피스(5)와 리턴피스(6) 사이에 틈새가 생기고, 이에 따라 클램프피스(5)가 언클램프상태가 되면서 로터리 테이블(4)이 로터리 베이스(2)에 대해 자유롭게 회전가능하게 된다.On the other hand, if the pressure oil supplied to the hydraulic port (P) is cut off, the return spring (S), which was compressed during the clamping operation, is restored and the return piece (6) is pushed upward, so that between the clamp piece (5) and the return piece (6) There is a gap therein, whereby the clamp piece 5 is unclamped so that the rotary table 4 is freely rotatable with respect to the rotary base 2.
이상과 같이 구성되고 작용되는 본 고안은, 종래와 비교해 부품수가 대폭 줄어들어 조립공차의 관리 및 가공에 유리하며 신뢰도가 높은 클램핑작용을 이루는 것으로, 그 구조 간단화에 따른 경제성이 높은 효과를 가지고 있다.The present invention is constructed and operated as described above, the number of parts is significantly reduced compared to the prior art to achieve the management and processing of the assembly tolerance, and to achieve a high clamping effect, has a high economic effect according to the simplified structure.
