본 고안은 선반과 같은 공작기계에 있어 공작물을 고정하는 척에 관한 것으로, 특히 척의 스크롤을 유압에 의해 작동하도록 하는 유압척에 관한 것이다.The present invention relates to a chuck for fixing a workpiece in a machine tool such as a lathe, and more particularly to a hydraulic chuck to operate the scroll of the chuck by hydraulic pressure.

제1도에는 종래의 스크롤척을 도시하고 있는 것으로, 척보디(101)와 척카버(102)안에 스크롤(103)과 조(104)를 내장하여 구성되며, 핸들을 기어레버(105)의 구멍에 끼워 기어레버를 회전시키면 베벨기어(106)가 회전하면서 스크롤(103)에 형성하고 있는 크라운기어(107)를 회전시키므로 스크롤(103)도 함께 회전되며, 이와같은 스크롤(103)의 회전에 따라 스크롤(103)에 치합된 3개의 조(104)가 척카버(102)의 가이드홈(102B)을 따라 중심축 쪽으로 이동하면서 조의 단부(104B)안쪽에 끼워진 가공물(W)을 단단히 붙잡게 되며, 이 상태에서 척(100)과 함께 가공물(W)을 회전시키면서 절삭바이트로 가공물(W)을 절삭 가공하거나 또는 척(100)과 함께 가공물(W)은 정지 상태로 절삭바이트를 회전시키면서 가공물(W)을 가공하도록 하고 있다.FIG. 1 shows a conventional scroll chuck, which includes a scroll 103 and a jaw 104 in the chuck body 101 and the chuck carver 102, and the handle is disposed in the hole of the gear lever 105. FIG. When the gear lever is rotated, the bevel gear 106 rotates to rotate the crown gear 107 formed on the scroll 103, so that the scroll 103 is also rotated together. As such, the scroll 103 is rotated. The three jaws 104 engaged with the scroll 103 move firmly along the guide grooves 102B of the chuck carver 102 toward the central axis and firmly hold the workpiece W fitted inside the jaws' end 104B. In this state, the workpiece W is cut with the cutting bite while the workpiece W is rotated together with the chuck 100, or the workpiece W with the chuck 100 rotates the cutting bit in a stationary state. ) To be processed.

그러나 이와같은 스크롤식 척은 가공물을 조에 붙잡고 또 풀때마다 핸들로 베벨기어를 풀었다가 조였다 하므로 매우 번거롭고 가공능률이 저하되었으며, 또한 조이는 힘이 약할때에는 가공도중 가공물이 조로부터 이탈하는 일이 발생하였다.However, this type of scroll chuck holds the workpiece in the jaw and releases and tightens the bevel gear with the handle every time it is unscrewed, which is very cumbersome and reduces the processing efficiency. Also, when the tightening force is weak, the workpiece is released from the jaw during processing.

그리하여 위와같은 문제점을 해결하기 위하여 유압식척을 사용하고 있는바, 종래의 유압식척은 제2도에 도시된바와 같이 척보다(201)와 척카버(202)안에 경사가 이드홈이 가공된 웨지플런저(203)를 내장하여 이 웨지플런저(203)의 경사가이드홈에는 조(204)를 조립하여 구성되며, 유압실린더(205)를 작동하여 견인봉(206)을 전,후진시키면 웨지플런저(203)가 전,후진하면서 조(204)를 축방향으로 조이거나 풀어주면서 가공물을 붙잡거나 풀어주도록 하고 있는 것이다.Therefore, a hydraulic chuck is used to solve the above problems, and the conventional hydraulic chuck is a wedge plunger in which an inclined guide groove is processed in the chuck 201 and the chuck cover 202 as shown in FIG. 203 is built in the inclined guide groove of the wedge plunger 203 is configured by assembling a jaw 204, the wedge plunger 203 by operating the hydraulic cylinder 205 to move the traction rod 206 forward and backward While squeezing or releasing the jaw 204 in the axial direction while reversing, the workpiece is to be held or released.

이와같은 유압식척은 조로 가공물을 붙잡고 푸는 작동을 자동적으로 수행하기 때문에 매우 편리하고 가공물의 장악력이 강하기 때문에 정밀가공물을 장시간 가공하는데에는 적합한 것이나, 장치가 매우 고가이고 정밀하기 때문에 설치비용이 많아지며, 또한 단순 가공물을 단시간에 대량으로 가공하는데 있어서는 정밀장치의 작동회수가 너무 많아지므로 인하여 장치의 고장이 빈번하여지는 문제점이 있었다.Such hydraulic chuck is very convenient because it automatically holds and unwinds the workpiece with a jaw, and it is suitable for long time machining of precision workpieces because of its strong grip, but the installation cost is high because the device is very expensive and precise. In addition, when processing a large amount of simple workpieces in a short time, the operation frequency of the precision device is too large, there is a problem that the failure of the device is frequent.

본 고안은 종래의 스크롤식척에 있어, 스크롤식척을 조작하는 기어레버와 베벨기어 및 크라운기어를 생략하고, 그대신 스크롤을 회전시키는 작동을 유압에 의해 이루어지도록 하므로서 극히 간단한 장치로 가공이 단순한 가공물을 단시간에 많은 양을 가공하기에 적합하도록 하는 유압척을 제공하고자 하는 것으로, 이를 첨부도면과 함께 설명하면 다음과 같다.The present invention omits the gear lever, the bevel gear and the crown gear that operate the scroll chuck in the conventional scroll chuck, and instead, the work of rotating the scroll is made by hydraulic pressure so that the workpiece can be easily processed with an extremely simple device. To provide a hydraulic chuck to be suitable for processing a large amount in a short time, it will be described with the accompanying drawings as follows.

제3도에는 본 고안에 따른 유압척을 분해사시도로 도시하고 있다.3 is an exploded perspective view of the hydraulic chuck according to the present invention.

본 고안에 따른 유압척은 종래의 척에 있어, 스크롤을 작동하기 위한 구성인 기어레버와 베벨기어 및 크라운기어를 생략하여 단순형상으로 스크롤(1)을 형성하고 있으며, 이 스크롤(1)을 작동시키기 위하여 작동레버(2)를 형성하고, 이 작동레바(2)는 고정구(B1)를 사용하여 스크롤(1)에 고정하도록 하며, 상기 작동레버(2)를 회전운동시키기 위하여 유압실린더(3)를 별도 준비하여 이 유압실린더의 로드(3R)를 상기 작동레버(2)에 고정하고 있으며, 유압실린더(3)에는 유압회로를 접속하여 콘트롤러에 의해 유압회로를 경유하여 유압을 교호로 공급하면서 유압실린더(3)가 작동하도록 하고 있다.The hydraulic chuck according to the present invention forms a scroll 1 in a simple shape by omitting a gear lever, a bevel gear, and a crown gear, which are components for operating a scroll in a conventional chuck, and operate the scroll 1. In order to form an actuating lever (2), the actuating lever (2) is fixed to the scroll (1) using a fastener (B1), the hydraulic cylinder (3) to rotate the actuating lever (2) And prepare a rod 3R of this hydraulic cylinder to the operating lever 2, and connect the hydraulic circuit to the hydraulic cylinder 3, supplying the hydraulic pressure alternately via the hydraulic circuit by the controller. The cylinder 3 is working.

이와같이 형성된 스크롤(1)과 작동레버(2)를 조립할 때에는 제4도 및 제5도에 도시된바와 같이, 척카버(4)의 가이드부(4B)를 따라 전,후진 운동하도록 조(5)를 조립하며, 이렇게 조립된 상기 조(5)의 기어(5B)와 스크롤(1)이 치합상태가 되도록 하여 이들을 척보디(6)와 척카버(4)안에 수납 장착하고 척보디(6)와 척카버(4)를 체결구(B3)로 고정하며 상기 작동레버(2)에는 유압실린더(3)의 로드(3B)를 연결 조립하므로서 작동레버(2)는 유압실린더(3)의 작동에 의해 일정한 각도 범위안에서 회전운동이 가능하도록 한다.When assembling the scroll 1 and the actuating lever 2 thus formed, as shown in FIGS. 4 and 5, the jaw 5 moves forward and backward along the guide portion 4B of the chuck cover 4. And the gears 5B and the scroll 1 of the jaw 5 assembled in this way are brought into engagement with each other, and they are housed in the chuck body 6 and the chuck cover 4, and the chuck body 6 and The chuck lever 4 is fixed by the fastener B3 and the actuating lever 2 is connected to and assembled by the rod 3B of the hydraulic cylinder 3 to the actuating lever 2 by the operation of the hydraulic cylinder 3. Allow rotational movement within a certain angle range.

제6도에서는 이와같이 형성되는 유압척을 공작기계의 축(S)에 고정하고 유압실린더(3)의 한쪽을 공작기계(L)의 어느 한쪽에 고정하며, 상기 유압실린더(3)에는 유압회로(도시하지 않음)를 접속하여 이 유압회로를 통하여 유압실린더(3)에 유압을 공급하여 유압 실린더를 작동하면, 작동레버(2)는 회전운동하면서 조(5)를 전,후진시켜 상기 조(5)가 가공물(W)을 붙잡고(고정하고) 절삭바이트(도시하지 않음)를 회전시키면서 가공물(W)을 가공하거나 또는 조(5)가 가공물(W)을 해제(풀어줌)하는 것을 도시하고 있는 것이다.In FIG. 6, the hydraulic chuck thus formed is fixed to the shaft S of the machine tool and one side of the hydraulic cylinder 3 is fixed to either side of the machine tool L. The hydraulic cylinder 3 has a hydraulic circuit ( (Not shown) to supply hydraulic pressure to the hydraulic cylinder 3 through this hydraulic circuit to operate the hydraulic cylinder, the operating lever 2 rotates the jaw 5 forward and backward while rotating the jaw (5). ) Hold (fix) the workpiece (W) and rotate the cutting bit (not shown) to process the workpiece (W) or the jaw (5) to release (unwind) the workpiece (W). .

제7도에는 유압척의 작동상태를 도시하고 있는 것으로, 조(5)가 열린상태(제7도의 (a)도)에서 조(5)안에 가공물(W)을 투입하고 난다음 유압실린더(3)를 작동하여 작동레버(2)를 회전(제7도의 (b)도에서 화살표 A방향으로)시키면 스크롤(1)이 회전하게 되며, 이에따라 스크롤(1)에 치합되어 있는 조(5)는 가공물(W)이 위치하고 있는 방향쪽으로 이동하여 가공물(W)을 단단하게 붙잡게 되는 것이며, 이 상태에서 절삭바이트(도시하지 않음)를 회전시키면서 가공물(W)을 가공하는 것이며, 가공이 끝난 다음에는 유압실린더(3)를 위와는 반대 방향으로 작동시켜 작동레버(2)를 회전(제7도의 (a)도에 있어 화살표 B방향으로)시키면, 스크롤(1)이 위와는 반대 방향으로 회전하면서 조(5)는 가공물(W)이 위치하고 있는 반대 방향으로 이동하여 가공물(W)을 해제하게 되므로 가공이 완료된 가공물(W)을 뽑아내고, 이 상태에서 가공하고자 하는 새로운 가공물(W)을 다시 조(6)안에 끼우고 위와같은 작동을 반복하게 되는 것이다.7 shows the operating state of the hydraulic chuck. After the workpiece W is introduced into the tank 5 in the state in which the jaw 5 is opened (Fig. 7 (a)), the hydraulic cylinder 3 When the operating lever 2 is rotated (in the direction of arrow A in FIG. 7 (b)), the scroll 1 is rotated. Thus, the jaw 5 engaged with the scroll 1 is moved to the workpiece ( It moves to the direction where W) is located and firmly holds the workpiece W. In this state, the workpiece W is machined while rotating a cutting bite (not shown). (3) in the opposite direction from above to rotate the operating lever 2 (in the direction of arrow B in Fig. 7A), the scroll (1) rotates in the opposite direction to the top (5). ) Moves in the opposite direction in which the workpiece (W) is located and releases the workpiece (W). The finished workpiece (W) is taken out, and the new workpiece (W) to be processed in this state is inserted into the tank (6) again and the above operation is repeated.

이와같이 본 고안에 따른 유압척은 스크롤(1)에 작동레버(2)를 장착하고 이 작동레버(2)를 유압실린더에 의해 작동하므로 그 구조가 매우 간단하고 가공물의 고정과 해체가 매우 빠르고 정확하므로 짧은시간에 대량의 가공물을 가공할 수 있으므로 단순 가공으로 대량의 가공물을 단시간에 가공하는데 매우 유익한 것이다.In this way, the hydraulic chuck according to the present invention is equipped with the operating lever (2) to the scroll (1) and operate the operating lever (2) by the hydraulic cylinder because the structure is very simple and the fastening and disassembly of the workpiece is very fast and accurate Since a large amount of workpieces can be processed in a short time, it is very advantageous to process a large amount of workpieces in a short time by simple processing.
