본 고안은 공작기계의 주축대에 착설되어 공작물을 고정하는 척에 죠대신 가공물 형상의 진공함실을 형성하여 진공압으로서 가공물을 고정하도록한 공작기계용 진공척 장치에 관한 것으로서, 전기밥솥등 박판으로 형성되어 찌그러지기 쉬운 가공물을 가공할때 죠대신 진공함실을 형성한 척을 사용하여 진공압으로 고정토록함으로서 이때 발생하는 제품의 변형을 방지하는데 그 목적이 있다.The present invention relates to a vacuum chuck device for a machine tool installed in a headstock of a machine tool to fix a workpiece by vacuum pressure by forming a vacuum chamber in the form of a workpiece instead of a jaw to fix the workpiece. The purpose of this is to prevent the deformation of the product which occurs at this time by fixing the vacuum pressure by using the chuck that formed the vacuum chamber instead of the jaw when processing the formed and vulnerable workpiece.

종래에는 가공물을 고정함에 있어서 주축의 면판에 3-4개의 죠를 가지는 척을 착설하여 죠가 가공물을 압착고정토록 하였기때문에 얇은 판으로 형성된 가공물을 가공할때는 죠의 압착력으로 인하여 첨부도면 제 3 도와 같이 가공물이 변형되기 때문에 가공을 할수 없거나 심지어는 제품이 손상되어 못쓰게 되는 예가 허다한 현실정이었다.Conventionally, in fixing the workpiece, the chuck having 3-4 jaws is installed on the face plate of the main shaft so that the jaw compresses the workpiece. Therefore, when processing a workpiece formed of a thin plate, the compression force of the jaw is used. Due to the deformation of the workpieces, there are many examples of the inability to process or even damage the product.

본 발명은 상기한 바와 같은 체결함을 감안하여 가공물을 고정하는 척에 진공함실을 형성하여 진공압으로 가공물을 고정토록함으로서 얇은 판으로된 가공물 고정시 죠에 의한 가공물의 변형이나 손상을 방지함과 동시에 원활한 가공을 할수있게 한것으로 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is to prevent the deformation or damage of the workpiece by the jaw to fix the workpiece by forming a vacuum chamber in the chuck to fix the workpiece in consideration of the fastening as described above to fix the workpiece by vacuum pressure and At the same time, it is possible to perform a smooth processing in detail according to the accompanying drawings as follows.

중공부(1a)가 형성된 주축(1)의 면판(2)에 척(3)을 착설하여 가공물을 고정토록된 공작기계에 있어서, 주연부에 다수의 통공(1')을 천설한 주축(1)의 후단에 캡(4)을 복착하여 그위에 유압호스(6)가 연결된 하우징(5)을 삽착하며, 주축(1) 전방의 면판(2)에는 가공물형상의 진공함실(3')을 형성한척(3)을 착설하여 상기 유압호스(6)와 연통토록하였으며, 상기하우징(5)과 주축(1)사이로 유로홈(11')을 환설한 부시(11)를 삽착하여 기밀을 유지하였으며, 상기 유압호스(6)는 진공펌퍼(8)와 압력펌퍼(9)에 연결된 솔레노이드 밸브(10)에 의하여 제어토록한것으로 미설명부호 13은 가공물이고 14는 종래척에서 가공물을 고정하는 죠이며, 15는 전동풀리 고정용키, 16은 베어링, 17은 기밀용 O링이다.In a machine tool in which a chuck (3) is installed on the face plate (2) of a spindle (1a) in which a hollow portion (1a) is formed, and a workpiece is fixed, the spindle (1) having a plurality of through holes (1 ') laid on its periphery. The cap 4 is attached to the rear end of the housing, and the housing 5 to which the hydraulic hose 6 is connected is inserted thereon. The face plate 2 in front of the main shaft 1 is formed with a workpiece-shaped vacuum chamber 3 '. (3) was installed to communicate with the hydraulic hose (6), and the bush 11 was inserted to maintain the airtight between the housing (5) and the main shaft (1) to maintain the airtight, the The hydraulic hose 6 is controlled by the solenoid valve 10 connected to the vacuum pump 8 and the pressure pump 9, where reference numeral 13 denotes a workpiece, 14 denotes a jaw for fixing the workpiece in the conventional chuck, and 15 Electric pulley fixing key, 16 is bearing, 17 is airtight O-ring.

이와같이 구성된 본 고안의 작용효과를 설명하면, 주축(1)의 면판(2)에 진공함실(3')이 가공할 물품과 일치하는 척(3)을 착설하여 가공물을 진공함실(3')에 삽입하고 제 2 도에 도시된 솔레노이드 밸브(10)의 작용으로 A부를 통하여 척(3)의 진공함실(3')과 연통된 유압호스(6)가 진공펌퍼(8) 연결되어 진공함실(3')에 진공압이 작용하면서 가공물을 흡착고정한다.Referring to the effect of the present invention configured as described above, the chuck (3) of the vacuum chamber (3 ') coincides with the object to be processed on the face plate (2) of the main shaft (1) by placing the workpiece in the vacuum chamber (3') The hydraulic hose 6 connected with the vacuum chamber 3 'of the chuck 3 through the A portion is inserted into the vacuum chamber 8 by the action of the solenoid valve 10 shown in FIG. Adsorption and fixation of workpieces under vacuum pressure

상기한 방법으로 흡착고정된 가공물은 전동모터와 연결된 전동풀리(12)에 의하여 주축(1)이 회전하면서 회전가공하게되고 가공이 완료된 가공물은 솔레노이드 밸브(10)의 작동으로 B부를 통하여 유압호스(6)가 압력펌퍼(9)에 연결되면서 진공함실(3')에 작용하던 진공압이 고압으로 바뀌어 가공물을 척(3)의 진공함실(3')밖으로 밀어내게 되어 가공물의 해체를 용이하게 한다.The workpiece fixed and fixed by the above method is rotated while the spindle 1 is rotated by the electric pulley 12 connected to the electric motor, and the finished workpiece is the hydraulic hose (B) through the operation of the solenoid valve 10. 6) is connected to the pressure pump 9, the vacuum pressure acting on the vacuum chamber 3 'is changed to a high pressure to push the workpiece out of the vacuum chamber 3' of the chuck 3 to facilitate the dismantling of the workpiece. .

상기한 바와같이 본 고안은 형상의 진공함실(3')을 형성한 척(3)으로 진공흡착에 의하여 가공물을 고정토록 하였기 때문에 얇은판으로 형성된 가공물을 고정할때 변형이 발생하여 가공을 하지 못하거나 제품 자체를 손상시킬 염려가 전혀없는 그 실사용 가치를 일층고양시킨 신규 유용의 고안이다.As described above, the subject innovation is to fix the workpiece by vacuum suction to the chuck 3 having the vacuum chamber 3 'of the shape. It is a new useful design that further enhances its practical value without fear of damaging the product itself.
