본 고안은 선반에 바아를 공급하는 바아공급장치에 관한 것이다.The present invention relates to a bar supply device for supplying a bar to the shelf.
종래의 선반작업에 있어서, 바아소재는 주축대의 스핀들 뒷면에 위치한 별도의 바아공급장치에 의해서 공급되므로 바아공급장치가 차지하는 면적이 증대되고 바아공급의 비절삭 시간이 많아서 생산성이 감소되었다.In the conventional lathe work, the bar material is supplied by a separate bar feeder located on the back of the spindle of the spindle, so that the area occupied by the bar feeder is increased and the productivity of the bar feeder is increased due to the large non-cutting time of the bar feeder.
본 고안의 목적은 상기와 같은 단점을 제거하기 위해서 기존 NC 선반의 공구대에 고정되는 바아공급장치를 제공하고자 하는 것이다.An object of the present invention is to provide a bar feeder that is fixed to the tool bar of the existing NC lathe in order to eliminate the above disadvantages.
제1도에는 본 고안의 바아공급장치의 사시도가 도시되는데, 몸체(1)는 직육면체의 박스형태를 지니며 몸체(1)의 전방에는 파지부(2)가 상하로 이동가능하게 설치된다. 파지부(2)의 후방면에는 더브테일돌기(3)가 돌출되고 몸체(1)의 전방에는 더브테일홈(4)이 형성되어 있다. 파지부(2)의 중간에는 돌출편(5)이 수직하게 돌출되어 어뎁터(6)가 설치되고 어댑터(6)의 하부에는 근접스위치(7)가 위치된다. 또한, 몸체(1)의 하부전방에는 댐퍼(8)가 돌출되어 있다.Figure 1 shows a perspective view of the bar supply apparatus of the present invention, the body (1) has a box shape of a rectangular parallelepiped, the front of the body (1) is installed so that the grip portion (2) is movable up and down. A dovetail protrusion 3 protrudes from the rear surface of the grip portion 2, and a dovetail groove 4 is formed in front of the body 1. In the middle of the gripping portion 2, the protruding piece 5 protrudes vertically so that the adapter 6 is installed, and the proximity switch 7 is located at the lower portion of the adapter 6. In addition, the damper 8 protrudes from the lower front of the body 1.
한편, 몸체(1)의 상부에는 유압실린더(9)가 부착되며 유압실린더(9)의 전방측벽(10)의 상부에는 리미트스위치(11)가 부착된다.On the other hand, the hydraulic cylinder 9 is attached to the upper portion of the body 1 and the limit switch 11 is attached to the upper portion of the front side wall 10 of the hydraulic cylinder (9).
제3도에는 본 고안의 바아공급장치 단면도로서 도시되는데, 유압실린더(9)속에는 피스톤(12)이 설치되며 피스톤(12)으로부터 피스톤로드(13)가 몸체(1)속으로 연장되어 있다.3 is a cross-sectional view of the bar feeder of the present invention, in which a piston 12 is installed in the hydraulic cylinder 9, and a piston rod 13 extends from the piston 12 into the body 1.
피스톤로드(13)의 한측면에는 랙(14)이 형성되어 있으며 랙(14)은 피니온(15)과 맞물려 있다. 또한 피니온(15)은 파지부(2)의 더브테일돌기(3)에 형성된 랙(16)과도 맞물려 있다.A rack 14 is formed on one side of the piston rod 13 and the rack 14 is engaged with the pinion 15. The pinion 15 is also engaged with the rack 16 formed on the dovetail protrusion 3 of the gripping portion 2.
상기와 같은 구성된 본 고안의 바아공급장치를 NC선반의 공구대에 고정시킴으로써 양방향성 12각(또는 10각) 고속 공구 분활장치인 공구대를 사용하여 4초 이내의 자동공구 교환시스템을 이용하고, X, Z축의 2축 개념을 최대한 활용할수 있다. 예컨대 이송대의 횡단속도는 각기 X축상으로 5m/min이고 축상으로 10m/min인 고속화 개념이 도입된 바아공급장치를 제공할수 있다.By using the tool bar of the bidirectional 12-angle (or 10-angle) high speed tool splitting device by fixing the bar feeder of the present invention configured as described above to the tool post of the NC lathe, the automatic tool changer system within 4 seconds is used. In other words, the two-axis concept of Z axis can be utilized. For example, it is possible to provide a bar feeding device in which a speed-up concept in which the traversing speed of the carriage is 5 m / min on the X axis and 10 m / min on the axis is introduced.
선반작업에 있어서, 파트 캐처(part catcher)를 통하여 가공된 소재가 도어 밖으로 반출된 후 소재를 공급하기 위한 본 고안의 바아공급장치의 작동순서는 다음과 같다.In the lathe operation, the operation sequence of the bar feeder of the present invention for supplying the material after the material processed through the part catcher is taken out of the door is as follows.
1. 파지부(1)가 있는 부분이 센터링되도록 공구를 분할시켜 준다. 2. 소재를 반입할수 있는 안전위치까지 공구대를 Z축 상에서 이동시킨다. 이때 공구대는 급속히 이동한 후에 소재 앞부분에서 감속된다. 3. 파지부(2)에 내장된 근접스위치(7)가 온 될 때가지 X축으로 공구대를 이동시킨다. 4. 근접스위치(7)가 온됨과 동시에 유압실린더(9)가 작동하여 피스톤로드(13)가 상승하고 파지부(2)가 하강하여 어댑터(6)과 댐퍼(7)사이에 바아소재를 파지하여 소재 공급할수 있는 초기 위치에 도달한다. 5. 일정시간(2-3초)일 지난뒤에 원하는 길이만큼 프로그램된 Z축 방향으로 공구대를 이동시킨다. 이때에 선반의 척킹은 해제된 상태로 된다. 6. 일정위치에 도달하면 선반은 바아소재를 다시 척킹한다. 7. 유압실린더(9)가 작동하여 피스톤로드(13)가 하강하고 파지부(2)가 상승하여 유압실린더(9)의 리미트스위치(11)를 작동시키면 파지부(2)는 정지한다. 8. 리미트스위치(11)의 작동으로 공구대는 X축 방향으로 이동하고 터렛을 회전시킬수 있는 부분까지 Z축 방향으로 이동한다. 9. 공구부분할후 작성된 프로그램에 의해서 소재를 가공한다.1. Divide the tool so that the part with the gripping part 1 is centered. 2. Move the tool post on the Z axis to the safe position where you can load the workpiece. The tool post then moves rapidly and then decelerates in front of the workpiece. 3. Move the tool post to the X axis until the proximity switch (7) built in the holding part (2) turns on. 4. At the same time the proximity switch (7) is turned on, the hydraulic cylinder (9) is operated to raise the piston rod (13) and the gripping portion (2) to lower and grip the bar material between the adapter (6) and the damper (7). To reach the initial position to supply the material. 5. After a period of time (2-3 seconds), move the tool bar in the direction of the programmed Z axis by the desired length. At this time, the chucking of the shelf is released. 6. When the lathe is reached, the lathe chucks the bar material again. 7. When the hydraulic cylinder (9) is operated, the piston rod (13) is lowered and the gripping portion (2) is raised to operate the limit switch (11) of the hydraulic cylinder (9), the gripping portion (2) is stopped. 8. With the operation of the limit switch 11, the tool post moves in the X-axis direction and in the Z-axis direction to the part where the turret can be rotated. 9. Machin the workpiece by the created program after tool part division.
상기와 같이 작동되는 본 고안의 바아공급장치는 종래의 바아공급장치가 30초대에서 작업되는데 비해서 15초대로 비절삭시간을 감소시킬수 있으며 NC화를 통해서 정확한 위치를 결정할수 있다.The bar supply device of the present invention operated as described above can reduce the non-cutting time to 15 seconds compared to the conventional bar supply device is operated in 30 seconds and can determine the exact position through the NC.
한편, 본 고안의 바아공급장치는 바아소재의 가공직경에 따라서 어댑퍼(6)의 형상을바꿀수 있으며 이에 따라서 리미트 스위치(11)를 상하로 이동시킬수 있는 브래킷을 제작하여 이용할 수 있다.On the other hand, the bar supply apparatus of the present invention can change the shape of the adapter 6 according to the processing diameter of the bar material, and thus can be used by making a bracket that can move the limit switch 11 up and down.
