본 고안은 방전가공기에 있어서 상하수직 왕복 운동을 하는 램의 운동을 사선왕복운동의 360°방향으로 전환시켜 주는 장치에 관한 것이다.The present invention relates to a device for converting the motion of the ram in vertical discharge reciprocating motion in the 360 ° direction of the diagonal reciprocating motion in the discharge processing machine.

종래의 방전 가공상태는 제4도와 같이 램이 상하 수직 왕복 운동을 하므로서 공작물에 사선 방향의 가공을 필요로 할때는 테이블에 고정시킨 공작물을 회전 시켜야 함으로 형상이 복잡한 금형등을 가공할 경우 공작물을 기울어지게 테이블에 부착시키기 어렵고, 특히 부피가 큰 공작물을 가공할때에는 공작물의 회전이 곤란한 결점이 있으며, 또한 공작물 가공은 테이블 위에 가공유가 담긴 가공탱크속에서 가공하여야 함으로서 공작물의 회전이 매우 불편한 결점이 있었다.In the conventional electric discharge machining state, as the ram is vertically reciprocated as shown in FIG. 4, when the workpiece requires diagonal machining, the workpiece fixed to the table must be rotated so that the workpiece is inclined when machining a mold having a complicated shape. It is difficult to attach to a table, and in particular, when machining a bulky workpiece, there is a defect in that the rotation of the workpiece is difficult. In addition, the workpiece machining has to be processed in a processing tank containing processing oil on the table.

본 고안은 종래와 같은 결점을 해소 하기 위하여, 가공탱크속에 고정된 가공물은 그대로 두고 상하 왕복운동을 하는 방전전극을 사선왕복 운동으로 전환되도록 한 것이다. 이하, 첨부도면에 의거 상세하게 설명하면 다음과 같다.The present invention is intended to convert the discharge electrode to the reciprocating reciprocating movement to the vertical reciprocating movement while leaving the workpiece fixed in the processing tank in order to eliminate the defects as in the prior art. Hereinafter, described in detail based on the accompanying drawings.

통상의 방전 가공기(100)에서 램(101)을 구동시키는 헤드(102)의 하단에 램(101)을 둘러싸듯, 방향회전안내홈(2a)을 형성한 고정대(2)를 부착하고, 상하 왕복운동을 하는 램(101)의 종단에 구동랙크(3)를 부착하고, 이와 맞물린 피니언(4)과 이 피니언(4)의 회전에 의하여 운동하는 종동랙크(5)가 부착되고, 종동랙크(5)의 끝단에는 방전 전극(6)을 부착하는 전극홀더(7)가 설치되었으며. 종동랙크(5)를 끼워서 사선왕복운동 각를 조절하는 각도조절구(8)와 이 각도 조절구(8)를 안내하는 각도조절홈(9)이 형성된 몸체(1)와 연결된지지대(10)가 고정대(2)의 방향 회전 안내홈(2a)에 삽입되고 고정핸들(11)로 고정되었으며, 각도 조절구(8)와 종동 랙크(5)를 고정하는 T볼트(12)가 몸체(1)와 각도 조절판(1')의 각도 조정홈(9)을 관통하여 고정핸들(11)로 고정된 구조로서, 미설명부호 (13)은 테이블, (14)은 가공탱크, (15)은 공작물이다.In the conventional electric discharge machine 100, the lower end of the head 102 for driving the ram 101 is attached to the fixing table 2 formed with the directional rotation guide groove 2a, and surrounds the ram 101. The drive rack 3 is attached to the end of the ram 101 to be moved, and the pinion 4 engaged therewith and the driven rack 5 moving by the rotation of the pinion 4 are attached, and the driven rack 5 At the end of the), an electrode holder (7) attaching a discharge electrode (6) is installed. The support (10) is connected to the body (1) formed with an angle adjusting device (8) for adjusting the reciprocating reciprocating angle by inserting a driven rack (5) and an angle adjusting groove (9) for guiding the angle adjusting device (8). Inserted into the directional rotation guide groove (2a) of (2) and fixed with a fixed handle (11), the T-bolt (12) for fixing the angle adjuster (8) and the driven rack (5) is angled with the body (1) Through the angle adjusting groove 9 of the adjusting plate 1 'is fixed to the fixed handle 11, reference numeral 13 is a table, 14 is a processing tank, 15 is a workpiece.

위와 같이 구성된 본 고안의 작용과 효과를 설명하면 제2도와 같이 헤드(102)의 하단에 램(101)을 가운데에 관통되게한 중공 형태의 고정대(2)를 부착시키고, 방향 회전안내홈(2a)에 지지대(10)를 끼우면 램(101)에 부착시킨 구동랙크(3)와 몸체(1)에 부설된 피니언(4)이 맞물리게 되어, 상하 왕복운동을 하는 구동랙크(3)가 피니언(4)을 회전시키고 또한 피니언(4)과 맞물린 종동랙크(5)가 왕복 운동을 하게된다.Referring to the operation and effect of the present invention configured as described above to attach the fixing guide (2) of the hollow form that allows the ram 101 to pass through the center of the head 102, as shown in Figure 2, the direction of rotation guide groove (2a) When the support 10 is inserted into the support rack 10, the drive rack 3 attached to the ram 101 and the pinion 4 attached to the body 1 are engaged with each other, and the drive rack 3 for vertically reciprocating motion is pinion (4). ) And also the driven rack 5 engaged with the pinion 4 to reciprocate.

이 종동랙크(5)의 사선왕복 운동의 각도는 몸체(1)의 각도 조절홈(9)과 각도조절구(8), 각도조절판(1')을 관통한 T볼트(12)로 조여서 고정한 고정핸들(11)을 돌려서 풀고 각도를 조절하게 된다.The angle of the oblique reciprocating movement of the driven rack 5 is fixed by tightening the T bolt 12 through the angle adjusting groove 9, the angle adjusting hole 8, and the angle adjusting plate 1 'of the body 1. The handle 11 is turned to loosen and adjust the angle.

또한 방향 회전안내홈(2a)에 고정한 지지대(10)의 고정핸들(11)을 풀고 이동시키면 사선으로 왕복운동하는 방전 전극(6)의 방향을 360°로 방향을 조절 할 수 있는 것이다.In addition, by releasing and moving the fixing handle 11 of the support (10) fixed to the directional rotation guide groove (2a) it is possible to adjust the direction of the discharge electrode 6 reciprocating diagonally to 360 °.

위와같이 작동하는 본 고안은 종래와같이 공작물을 회전 시켜서 가공하던 불편을 해소 함으로서 작업능률율 향상시키고, 특히 구조가 복잡하고 부피가 큰 공작물도 원하는 각도에서 용이하게 작업을 실시 할수있으므로 정밀하고 어려운 가공도 쉽게 행할수 있는 매우 유용한 고안인 것이다.The present invention works as described above to improve the work efficiency by eliminating the inconvenience of machining by rotating the workpiece as in the prior art, and in particular, complicated and bulky workpieces can be easily performed at the desired angle, precise and difficult machining Is a very useful design that can be done easily.
