카트리지 타입 스핀들 유닛의 냉각장치{cooling device of cartridge type spindle unit}Cooling device of cartridge type spindle unit

본 발명은 주축을 고속회전할 수 있게 하는 카트리지 타입의 스핀들 유닛에서 스핀들에 내장된 대형 빌트인 모터(30kW급)와 베어링을 냉각하는 쿨링시스템 및 베어링 윤활시스템, 절삭유 공급관로 확보 등의 기능을 스핀들에 일체화하고 컴팩트하게 하여 스핀들 유닛을 헤드바디에 용이하게 장착하거나 분리할 수 있게 한 것에 관한 것이다.The present invention is a cartridge type spindle unit that allows the main shaft to rotate at high speed, the built-in large built-in motor (30kW class) and cooling system for cooling the bearing, bearing lubrication system, securing the coolant supply pipe, etc. The invention relates to an integrated and compact body which makes it easy to mount or detach the spindle unit from the head body.

공작기계분야의 주축은 고속회전특성과 더불어 회전정밀도, 주축의 가감속 능력 등 까다로운 기술적 시방이 요구되는 분야이다.The main axis of the machine tool field is a demanding technical specification such as rotational precision, acceleration and deceleration capability of the main axis, as well as high-speed rotation characteristics.

또한 공작기계의 고속화추세에 따라 고속주축에 대한 기술의존성이 증대하고 있으며 넓게는 공작기계, 자동차산업 전반에서 폭넓게 사용되는 핵심요소기술이라 할 수 있다.In addition, technology dependency on high speed spindles is increasing according to the trend of high speed of machine tools, and it can be said to be a core element technology widely used in the machine tool and automobile industries.

공작기계의 주축은 스핀들 베어링에 의해 지지되는 구조로 벨트 또는 커플링 을 매개로 하여 스핀들 모터의 동력을 전달받는 구조로 구성되는 것이 일반적이었으며 주축의 고속화를 위해서 주축과 스핀들 모터를 직결하는 카트리지 타입으로 대체되고 있으나, 이는 스핀들 모터로부터 발생하는 열이 주축의 변형을 가져오게 되어 정밀도를 저하시키며 베어링을 소착시키는 문제점이 있었으므로 고속화에 한계가 있었으므로 스핀들에 내장된 모터와 베어링을 강제냉각하는 장치가 제안되고 있었다.The spindle of a machine tool is a structure supported by a spindle bearing. It is generally composed of a structure that receives the power of a spindle motor through a belt or a coupling. It is a cartridge type that directly connects the spindle and the spindle motor to speed up the spindle. However, this is because the heat generated from the spindle motor causes deformation of the main shaft, which lowers the precision and causes the bearing to squeeze. It was proposed.

종래 스핀들 유닛에 내장되는 스핀들 모터와 베어링의 강제냉각장치로는 KR공개특허제1989-0702319호(1989.12.23공개)에서는 도 1과 같이 고정자(1)의 외측원주의 외측슬리브(4) 상에 형성된 입구개구(30)로부터 출구개구(32)까지 연장하는 통로를 형성하기 위해 그 외측 원주에 형성되고 외측슬리브(4)로 덮인 나선홈(31)을 가지는 오일자켓(3)이 제공되며, 냉각유체는 화살표(F₁,F₂)로 표시된 통로를 통과하며 모터의 고정자(1)를 피복층으로 피복하고 고정자 코일의 돌출부(10) 및 회전자(2)의 대향단부에 냉각유체를 인가함을 특징으로 하는 모터냉각시스템이 공지된바 있었으나, 상기의 구성에서 냉각유체는 스핀들의 외주면에 형성된 입구개구(90)에서 출구개구(92)쪽으로 흐르도록 구성되어 있어 냉각유체의 입·출구가 스핀들의 외주면에 형성됨으로써 스핀들 유닛의 외경이 커지고 냉각유체 입·출구 및 절삭유 관련 유로가 헤드바디에 형성될 수 밖에 없으므로 구조가 복잡해지고 비대해져 스핀들 유닛의 장착 및 탈착에 불편함이 있었다.As a forced cooling device for a spindle motor and a bearing, which is incorporated in a conventional spindle unit, KR Publication No. 1989-0702319 (published on December 23, 1989) shows an outer sleeve 4 of the outer circumference of the stator 1 as shown in FIG.

Spiral grooves are formed on the outer surface of the spindle jacket sleeve that incorporates the oil path to form the oil passage. On the outer surface of the oil passage, the outer surface of the spindle is wrapped with a thin iron plate (t1.2 to 1.6) and sealed by welding to prevent fluid leakage.

이하에서 본 발명의 바람직한 실시 예에 대하여 첨부한 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도면에 도시한 바와 같이 본 발명은 카트리지 타입 스핀들 유닛의 공구장착부를 갖는 주축(102) 외경면의 프런트베어링(106)을 감싸며 냉각시키는 프런트하우징(101)과, 주축(102)을 회전시키는 빌트인 모터(103)를 내장하는 자켓슬리브(104)와, 주축(102)의 후단부에 위치하여 공구를 교체하기 위한 동작을 하는 언클램핑 유니트(105)로 구성되어 있다.As shown in the drawing, the present invention is a front housing 101 for wrapping and cooling the front bearing 106 of the outer diameter surface of the main shaft 102 having the tool mounting portion of the cartridge type spindle unit, and a built-in motor for rotating the main shaft 102. A jacket sleeve 104 having a built-in 103 and an unclamping unit 105 positioned at the rear end of the main shaft 102 to perform tool replacement.

프런트하우징(101)과 주축(102)사이에서 프런트베어링(106)이 다수개(3열~4열) 구비되며, 프런트베어링(106)에는 앵귤러 컨택트 볼베어링이 적용되어 고속회전에 적합하게 구성된다.Between the front housing 101 and the main shaft 102, a plurality of front bearings 106 (three rows to four rows) are provided, and the front bearings 106 are angular contact ball bearings configured to be suitable for high speed rotation.

프런트베어링(106)은 주축(102)의 고속회전에 따른 회전저항과 빌트인모터(103)의 발열로 인하여 온도가 상승하므로 브라켓(117)의 후단부에 형성된 냉각액유입구A(107)를 통하여 유입되는 냉각액을 자켓슬리브(104)의 내부에 천공되는 유로를 통하여 프런트하우징(101)과 슬리브커버(108) 사이로 냉각유체를 공급하여 프런트베어링(106)을 냉각한 다음, 냉각액은 연결관로(109)를 통하여 자켓슬리브(104)의 냉각자켓(110)으로 이동시켜 슬리브에 형성된 나선형의 유로를 따라 슬리브의 원주를 순환하면서 빌트인 모터(103)에서 발생하는 열을 냉각한 다음 냉각액배출구A(111)로 배출하여 오일탱크(112)로 복귀시킨다.The front bearing 106 is introduced through the coolant inlet A 107 formed at the rear end of the bracket 117 because the temperature rises due to the rotational resistance of the main shaft 102 and the heat generated by the built-in motor 103. Cooling liquid is supplied between the front housing 101 and the sleeve cover 108 through a flow path drilled inside the jacket sleeve 104 to cool the front bearing 106, and then the cooling liquid passes through the connecting pipe passage 109. It moves to the cooling jacket 110 of the jacket sleeve 104 through to circulate the circumference of the sleeve along the spiral flow path formed in the sleeve to cool the heat generated by the built-in motor 103 and then discharged to the coolant outlet A (111) To return to the oil tank 112.

냉각자켓(110)은 자켓슬리브(104)의 원주에 냉각유로가 연속적으로 형성되도록 나선방향으로 감기는 형태로 입구와 출구가 연결되도록 구성한다.The cooling jacket 110 is configured to connect the inlet and the outlet in the form of winding in a spiral direction so that a cooling flow path is continuously formed on the circumference of the jacket sleeve 104.

자켓슬리브(104)에 형성되는 냉각유로의 바깥쪽은 얇은 철판(t1.2~1.6)으로 자켓슬리브(104)를 감싼 후 용접에 의하여 밀폐하여 냉각수의 누출이 방지되도록 구성한다.The outer side of the cooling flow path formed in the jacket sleeve 104 wraps the jacket sleeve 104 with a thin iron plate (t1.2 to 1.6) and is sealed by welding to prevent leakage of the cooling water.

리어하우징(114)에 내장되는 리어베어링(118)도 주축(102)의 회전저항과 빌트인 모터(103)의 발열로 인하여 온도가 상승하므로 냉각이 필요하다.The rear bearing 118 embedded in the rear housing 114 also needs cooling because the temperature rises due to the rotational resistance of the main shaft 102 and the heat generation of the built-in motor 103.

리어베어링(118)에 대한 냉각은 브라켓(117)의 측면에 구비된 냉각액유입구 B(113)를 통하여 유입된 냉각액이 리어베어링(118)을 지지하는 리어하우징(114)에 형성된 오일통로(115)를 통하여 순환하고 브라켓(117)의 측면에 구비된 냉각액배출구B(116)를 통하여 오일탱크(112)로 복귀하게 구성된다.Cooling for the rear bearing 118 is the oil passage 115 formed in the rear housing 114, the cooling liquid introduced through the coolant inlet B 113 provided on the side of the bracket 117 supports the rear bearing 118 It is configured to circulate through and return to the oil tank 112 through the coolant outlet B 116 provided on the side of the bracket 117.

따라서 본 발명은 30kW급 대형 빌트인 모터(103)를 외경 290mm이하의 자켓슬리브(104)에 내장하여 베어링(106,118)과 빌트인 모터(103)의 냉각, 윤활은 물론 절삭유 관로까지 집약시킨 컴팩트한 구조의 카트리지 타입으로 헤드바디에 장착하거나 분리하는데 간섭이 없어 유지보수 시간이 단축되고 외관상으로도 깨끗하다.Therefore, the present invention has a compact structure in which a 30kW class built-in motor 103 is integrated into a jacket sleeve 104 having an outer diameter of 290 mm or less, condensing cooling and lubrication of the bearings 106 and 118 and the built-in motor 103 as well as the cutting oil pipeline. The cartridge type eliminates interference in mounting or detaching the headbody, which shortens maintenance time and is clean in appearance.
