본 고안은 로터리 밸브를 이용한 밀링머쉰용 클램프지그에 관한 것으로서 특히 동일제품을 다량 생산하면서 공작물고정시 큰 고정력이 필요할때에 적합하도록 한 것이다.The present invention relates to a clamping jig for a milling machine using a rotary valve, in particular, to produce a large amount of the same product to be suitable when a large fixing force is required when fixing the workpiece.
다량 생산을 위한 밀링머쉰은 제1도에서와 같이 고정축(1)을 중심으로 회전하는 회전테이블(2)상에 방사형으로 수개의 바이스(3)를 설치해놓은후 회전시켜 일측에서는 절삭공구가 내려와 절삭작업을 수행하게 하고 동시에 그 정반대쪽에서는 절삭작업이 끝나고 회전되어 돌아온 공작물(A)을 빼고 새 공작물로 바꾸어주는 작업을 계속적으로 하게 된다.Milling machine for mass production is installed radially on the rotary table 2 rotating around the fixed shaft 1 as shown in FIG. 1 and then rotated after installing several vises 3 on one side. At the same time, the opposite side of the cutting work is completed and the work A, which is rotated and removed, is removed and replaced with a new work.
이러한 작업중 종래의 문제점은 공작물을 고정시켜 주기 위한 고정 수단으로서 나사축을 이용한 일반적인 바이스(3)를 사용하고 있다는 점인데 이는 풀고조이는 시간이 많이 소요되므로 공작물 교체작업을 회전테이블(2)의 회전속도에 맞추기 위해서는 작업자가 계속 바쁘게 움직여야만 하며 또한 공작물을 절삭공구(22)의 진동 및 회전력에 견딜수 있도록 견고히 조여주어야 하는데 이것은 오로지 작업자의 인력에 의존하는 것이므로 작업자가 지친다거나 회전테이블(2)의 회전속도에 맞추지 못해 바이스를 완전히 고정시키지 못하고 넘어가는 경우 불량품 생성은 물론 절삭공구의 회전력에 의해 공작물(A)이 튀어나가 안전사고까지 발생할 우려가 있는 것이다.The conventional problem in this work is that a general vice 3 using a screw shaft is used as a fixing means for fixing a work, which is time consuming to loosen and tighten, so that the work of replacing the work with the rotational speed of the rotary table 2 is fixed. In order to fit, the operator must keep busy and tighten the workpiece firmly to withstand the vibration and rotational force of the cutting tool 22. It is only dependent on the worker's manpower, and the operator is tired or at the rotational speed of the rotary table 2. If the vise cannot be completely fixed and the vise cannot be fixed, the workpiece A may pop out due to the rotational force of the cutting tool as well as the generation of defective products, which may cause a safety accident.
본 고안은 이러한 종래의 결점을 해결하기 위해 안출된 것으로서 나사식 바이스 대신 유압실린더를 사용하고 이 유압실린더의 클램핑 및 언클램핑 시간을 로터리 밸브와 캠을 이용하여 항상 일정하도록 해주므로서 작업자가 작업의 일관성을 갖을수 있도록 하고 또한 언제나 견고한 클래핑이 유지될수 있도록 한 것으로서 그 구성 및 작용효과를 첨부 도면에 의거 상세히 설명하면 다음과 같다.The present invention was devised to solve the above-mentioned drawbacks. The hydraulic cylinder is used instead of the threaded vice, and the clamping and unclamping time of the hydraulic cylinder is always constant by using a rotary valve and a cam. In order to be consistent and also to maintain a strong clapping at all times, the configuration and effect will be described in detail based on the accompanying drawings as follows.
베이스상면(5)에 일정각을 갖도록 다수의 실린더(6)를 방사상으로 부착하여 회전테이블(2)을 형성하고 그 중앙의 고정축(3)위에는 외환부 일측에 언클램핑 요홈부(7)를 가진 원판캠(8)을 고정시키며 그 직상방에서 로터리 밸브(9)가 회전 테이블(2)과 같이 회전되도록 고정되어 있다.A plurality of cylinders 6 are radially attached to the base upper surface 5 to form a rotary table 2, and an unclamping recess 7 is formed on one side of the foreign exchange part on a fixed shaft 3 in the center thereof. The excitation disc cam 8 is fixed and the rotary valve 9 is fixed so as to rotate like the rotary table 2 above.
로터리 밸브(9)는 베이스(5)상의 실린더(6)수와 일치되도록 다방향으로 통공된 상부유입도공(10) 및 하부 배출유도공(11)이 각각 중앙에서 교차되어 상부 유입유도공(10)은 유입구(12)와 연통되고 하부 배출유도공(11)은 배출구(13)와 연통되게 형성되어 있다.The rotary valve 9 has an upper inflow hole 10 and a lower discharge induction hole 11 intersected at the center so as to match the number of cylinders 6 on the base 5, respectively. In communication with the inlet 12 and the lower discharge induction hole 11 is formed in communication with the outlet (13).
또 상부유입유도공(10)과 하부 배출유도공(11)은 바깥쪽에서 협소부(14)를 가진 수직공(15)으로 서로 연통되며 그 수직공(15)의 협소부(14)내의 윗쪽에는 강구(16)와 스프링(17)을 끼운후 플러그(18)로서 막고 그 아래쪽에서는 상면에 수직핀(19')이 있고 중간에 누압방지용 O링(20)이 감긴 플런져(19)를 끼워 원판캠(8)의 캠면을 따라 상하작동하도록 되어 있으며 협소부(14)의 측방향에서 형성된 실린더 호오스 연결공(21)에 각각의 실린더(6)를 연결하여 공작물(A)을 클램핑, 언클램핑 하도록 하여서 된 것이다.In addition, the upper inflow guide (10) and the lower discharge guide (11) is communicated with each other as a vertical hole (15) having a narrow portion 14 from the outside and the steel ball (top) in the narrow portion 14 of the vertical hole (15) 16) and the spring 17 are inserted and plugged into the plug 18, and at the bottom thereof, a vertical pin 19 'is placed on the upper surface and a plunger 19 wound around the pressure preventing O-ring 20 is inserted in the middle of the disc cam ( It is designed to operate up and down along the cam surface of 8) and to connect each cylinder 6 to the cylinder hose connecting hole 21 formed in the lateral direction of the narrow portion 14 to clamp and unclamp the work A. will be.
도면중 미설명 부호 22는 절삭공구, 23은 작업자, 24는 베어링이다.In the figure, reference numeral 22 denotes a cutting tool, 23 operator, and 24 bearing.
이렇게 하여서된 본 고안은 제4도에서와 같이 비도시된 동력전달에 의해서 회전테이블(2)이 회전을 하게 되면 중앙에 고정된 로터리 밸브(9)가 같이 돌게 된다.In this way, the present invention, as shown in Figure 4, when the rotary table 2 is rotated by the power transmission not shown, as shown in Figure 4, the rotary valve 9 fixed in the center is rotated together.
로터리 밸브(9)의 저면에는 베이스(5)상의 각실린더(6)와 동일한 각도 배열의 위치에 플런저(19)가 돌출되어 있어 이들이 중심축(1)에 고정된 원판캠(8)의 캠면을 눌린 상태로 타고 돌다가 제5도 및 제6도에서 보는 바와같이 작업자(23)쪽에 있는 요홈부(7)에 이른 플런저(19)는 수직공(15)내부에 스프링(17)이 누르는 힘에 의해 돌출되게 된다.Plungers 19 protrude from the bottom surface of the rotary valve 9 at the same angular arrangement as the angle cylinders 6 on the base 5 so that the cam surface of the disc cam 8 fixed to the central axis 1 is fixed. As shown in FIGS. 5 and 6, the plunger 19 reaches the groove 7 on the operator 23 side by pressing the spring 17 in the vertical hole 15 as shown in FIGS. 5 and 6. To protrude.
이렇게 되면 강구(16)는 협소부(14)를 막아 상부 유입유도공(10)쪽을 차단시키고 내려간 플런저(19)의 상단은 하부 배출유도공(11)을 개방하게 되어 실린더(6)의 유압이 하부 배출유도공(11)을 따라 배출구(13)로 빠져 나가므로 작업자(23)앞의 실린더(6)는 공작물(A)을 교체하여 줄수 있도록 후퇴하게 된다.In this case, the steel ball 16 blocks the narrow portion 14 to block the upper inflow guide 10 and the upper end of the lowered plunger 19 opens the lower discharge guide 11 so that the hydraulic pressure of the cylinder 6 is lowered. The cylinder 6 in front of the operator 23 is retracted to replace the work piece A because it exits to the discharge port 13 along the discharge induction hole 11.
이때 요홈부(7)외의 캠면을 돌고 있는 플런저(19)들은 눌려진 상태가 계속 유지된다.At this time, the plungers 19 turning the cam surface other than the recess 7 remain pressed.
따라서 플런저(19)의 상단은 하부 배출유도공(11)을 차단하고 있고 수직핀(19')은 강구(16)를 밀어올려 협소부(14)를 개방하고 있으므로 유입구(12), 상부 유입유도공(10)을 통해 들어온 유압이 협소부(14)를 지나 실린더(6)에 전달되어 공작물(A)을 지속적으로 클램핑시킬수 있는 것이다.Therefore, the upper end of the plunger 19 blocks the lower discharge induction hole 11 and the vertical pin 19 'pushes the steel ball 16 to open the narrow portion 14, so that the inlet 12 and the upper induction hole ( The hydraulic pressure introduced through 10) is transmitted to the cylinder 6 through the narrow portion 14 so that the workpiece A can be continuously clamped.
이러한 상태로 회전테이블(2)이 계속 회전하게 되면 원판캠(8)의 요홈부(7)를 지나던 플런저(19)가 평면으로 올라서게 되고 따라서 수직핀(19')이 강구(16)를 밀어올려 협소부(14)를 개방하게 되므로 유압은 실린더(6)에 전달되어 세로물려진 공작물(A)을 클램핑하게 되며, 반대로 요홈부(7)로 내려간 플런저(19)는 협소부(14)를 차단시켜 실린더(6)의 유압을 제거하게 되므로 공작물(A)을 언클램핑하게 되는 것이다.When the rotary table 2 continues to rotate in this state, the plunger 19 passing through the recess 7 of the disc cam 8 rises to the flat surface, and thus the vertical pin 19 'pushes up the steel ball 16. Since the narrow portion 14 is opened, the hydraulic pressure is transmitted to the cylinder 6 to clamp the vertically stitched workpiece A. On the contrary, the plunger 19 lowered to the recess portion 7 blocks the narrow portion 14. By removing the hydraulic pressure of the cylinder (6) it is to unclamp the workpiece (A).
이렇게 작업자(23) 앞부분에온 실린더(6)는 공작물(A)을 언클램핑하고 그외의 실린더(6)는 모두 클램핑 상태가 유지된 상태로 계속 돌아가게 된다.In this way, the cylinder 6 in front of the operator 23 unclamps the workpiece A, and all other cylinders 6 continue to return to the state in which the clamping state is maintained.
이와 같은 본 고안은 종래에 나사축을 이용한 바이스로 공작물(A)을 클램핑 하던것에 비해 유압실린더(6)를 이용하므로서 신속하면서도 더욱 견고한 클램핑을 할수 있고, 또한 로터리 밸브(9)와 캠(8)을 이용한 클램핑, 언클램핑 시간이 항상 일정하므로 작업자는 일관성있고 여유있는 반복작업을 하게 되어 작업능률이 향상될 수 있는 유용한 고안인 것이다.The present invention is faster and more robust clamping by using the hydraulic cylinder (6), compared to the conventional clamping the workpiece (A) in the vise using a screw shaft, and also the rotary valve (9) and cam (8) Since the clamping and unclamping times used are always constant, it is a useful design that can improve the work efficiency by allowing the worker to perform consistent and relaxed repetitive work.
