본 발명은 밀링머신 등의 공작기계에 공작물을 고정함에 있어서, 이 밀링머신의 인덱스 원형판에 인덱스 가능한 원형지그를 설치하여 상기 공작물을 용이하면서 견고하게 고정시키고 상기 인덱스 각도 지지대의 각도를 조정하더라도 공구와 공작물 사이에 가공작업이 방해되지 않는 거리를 확보할 수 있도록 한 공작물 고정장치에 관한 것이다.In the present invention, in fixing a workpiece to a machine tool such as a milling machine, an indexable circular jig is installed on an index circular plate of the milling machine, thereby easily and firmly fixing the workpiece and adjusting the angle of the index angle support. The present invention relates to a workpiece holding device that can secure a distance between workpieces that does not interfere with machining operations.

종래 밀링머신에서 피가공물인 공작물을 고정함에 있어서는 제1도에 도시된 바와같이, 공작물(1)을 인덱싱 가공하기 위한 삼본척(2)을 인덱스 원형판(3)에 T볼트(4)로 체결고정시키고 육각렌치등의 공구를 사용하여 상기 삼본척(2)의 가동죠(5)를 이동시켜 공작물(1)에 근접배치한 다음 클램프(6)와 T볼트(7)로 공작물을 고정시킨 상태에서 밀링머신의 콜렛척(8)에 장착된 공구(9)를 작동시켜 공작물(1)을 가공하도록 되어있었다.In fixing a workpiece as a workpiece in a conventional milling machine, as shown in FIG. 1, a three-bone chuck 2 for indexing the workpiece 1 is fastened to the index circular plate 3 with a T bolt 4. After moving the movable jaw (5) of the three main chuck (2) using a tool such as a hexagon wrench and placed close to the workpiece (1), while holding the workpiece fixed with the clamp (6) and T bolt (7) The tool 9 mounted on the collet chuck 8 of the milling machine was operated to machine the work 1.

그러나, 상기와 같은 종래의 것은 공작물(1)의 인덱싱 작업시 삼본척(2)의 두께가 너무 두껍기 때문에 공작물을 셋팅하고 인덱스 각도 지지대(10)의 각도를 상향 조정할 경우, 테이블(11)로부터 공구(9)까지의 거리상 한계 때문에 공작물을 가공할 수 없게 되는 경우가 발생되는 문제점이 있었다.However, the above-described conventional method is so thick that the three-bone chuck 2 is too thick in the indexing operation of the workpiece 1, so that when the workpiece is set and the angle of the index angle support 10 is adjusted upward, the tool from the table 11 is used. There was a problem that the workpiece could not be machined due to the distance limit to (9).

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 밀링머신 등의 공작기계에 공작물을 고정함에 있어서, 이 밀링머신의 인덱스 원형판에 인덱스 가능한 원형지그를 설치하여 상기 공작물을 용이하면서 견고하게 고정시키고 상기 인덱스 각도 지지대의 각도를 조정하더라도 공구와 공작물 사이에 가공작업이 방해되지 않는 거리를 확보할 수 있도록 한 공작물 고정장치를 제공하려는 것이다.The present invention has been made to solve the above-mentioned conventional problems, in fixing a workpiece to a machine tool such as a milling machine, by installing an indexable circular jig on the index circular plate of the milling machine, the workpiece is easily and firmly It is intended to provide a workpiece holding device to secure a distance that does not interfere with the machining work between the tool and the workpiece even if the fixed angle and the angle of the index angle support is adjusted.

본 발명에 따른 공작물 고정장치는 인덱스 각조 지지대상에서 각도 조정가능한게 배치하여 설치되며 죠가 구비된 인덱스 원형판 상면에 인덱싱 포인트가 각인되어 있고 반경방향 외측에 등간격으로 다수의 볼트구멍이 형성된 원형지그와 공작물을 원형지그에 대하여 고정시킴과 함께 상기 원형지그를 인덱싱 원형판에 대하여 고정시키는 클램핑 수단을 포함하여 구성된다.The workpiece fixing device according to the present invention is installed by arranging the angle adjustable in the index square support object, the index jig is stamped on the upper surface of the index circular plate with a jaw and a circular jig formed with a plurality of bolt holes at equal intervals on the radially outer side. And clamping means for fixing the workpiece against the circular jig and fixing the circular jig against the indexing circular plate.

이하, 본 발명의 일실시예를 첨부한 도면을 참고하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도에서, 본 고안에 따른 인덱스 가능한 원형지그(20)에는 그 중심으로부터 반경방향 외측으로 등거리에 등간격으로 복수개의 볼트구멍(21)에 형성되어 있으며 그 표면에는 공작물 인덱싱을 위한 인덱싱 포인트가 각인되어 공작물을 인덱싱하여 고정한다.In FIG. 2, the indexable circular jig 20 according to the present invention is formed in the plurality of bolt holes 21 at equal intervals at equal distances radially outward from the center thereof, and an indexing point for workpiece indexing is formed on the surface thereof. Engraved to index and fix the workpiece.

상기 원형지그(20)는 제3도에 도시된 바와같이, 클램프(24)에 설치되는 T볼트(22)를 볼트구멍(21)에 체결하는 상태에서 기존의 인덱스 원형판(23)에 장착되며 공작물(1)의 고정은 공작물을 원형지그(20)에 배치하고 클램프(24)의 일단으로 고정시킨다.The circular jig 20 is mounted on the existing index circular plate 23 in a state of fastening the T bolt 22 installed in the clamp 24 to the bolt hole 21, as shown in FIG. The fixing of (1) arranges the workpiece in the circular jig 20 and fixes it with one end of the clamp 24.

또, 상기 클램프(24)는 전단부를 공작물(1)의 기초부를 지지하도록 한 상태에서 그 후단부를 인덱스 원형판(23) 외측 원주부에 형성된 죠(25)의 적합한 단(27)위에 걸치도록 설치하며 이 클램프(24)에 설치되는 T볼트(26)를 인덱스 원형판(23)에 고정시켜 클램프(24)가 상기 원형지그(20)의 상면을 누르는 형태로 고정하므로써 상기 클램프(24)가 공작물(1)과 함께 상기 원형지그(20)를 T볼트(26)로 인덱스 원형판(23)에 일체형으로 고정시키게 되고 상기 클램프(24)는 원형지그(20)에 형성된 볼트구멍(21) 위치에 대응하여 장착된다.In addition, the clamp 24 is installed so that the front end portion is supported on the appropriate end 27 of the jaw 25 formed on the outer circumference of the index circular plate 23 in a state in which the front end portion supports the base portion of the work piece 1. The clamp 24 is fixed to the index circular plate 23 by fixing the T bolt 26 provided in the clamp 24 in the form of pressing the upper surface of the circular jig 20 so that the clamp 24 is the workpiece (1). ) Together with the circular jig 20 is fixed integrally to the index circular plate 23 by the T-bolt 26 and the clamp 24 is mounted corresponding to the position of the bolt hole 21 formed in the circular jig 20 do.

상술한 바와같이, 본 발명에 의한 원형지그(20)를 인덱스 원형판(23)에 고정시키고 그 위에서 공작물(1)을 인덱싱하여 복수개의 클램프(24)로 공작물(1)을 클램핑 함으로써 종래 공작물 고정용 삼본척을 사용하지 않고도 인덱스 원형판에 견고하게 장착할 수 있다.As described above, by fixing the circular jig 20 according to the present invention to the index circular plate 23, indexing the workpiece (1) thereon and clamping the workpiece (1) with a plurality of clamps 24 for fixing the conventional workpiece It can be mounted firmly on the index circular plate without using the three bone chuck.

종래의 삼본척은 공작물을 고정하기 위하여 가동 죠와 그 가동장치를 구비하기 때문에 삼본척의 두께가 적어도 100㎜인 반면, 본 발명에 따라 표면에 인덱싱 포인트가 각인된 원형지그(20)는 별도의 클램핑 수단이나 죠를 내장하고 있지 않으므로 단지 20㎜정도이면 충분하며, 따라서 종래의 공작물 고정장치에서 보다 공구(9)와 공작물(1)사이에 충분한 거리가 확보되어 인덱스 각도 지지대(10)의 회전시에도 공작물 가공을 원활하게 할 수 있는 장점이 있다.The conventional three-bone chuck has a movable jaw and its movable device to fix the work, so that the thickness of the three-bone chuck is at least 100 mm, whereas the circular jig 20 in which the indexing point is imprinted on the surface is clamped separately. Since no means or jaws are built in, only about 20 mm is sufficient, so that a sufficient distance is secured between the tool 9 and the work piece 1 in the conventional work holding device, so that even when the index angle support 10 is rotated. There is an advantage to smooth workpiece processing.
