본 발명은 공작기계의 인덱스테이블에 관한 것으로, 보다 상세하게는 인덱스테이블을 직접 구동방식으로 회전시키고 고정밀도로 각도분할된 테이블을 테이블에 고정할 수 있게 하는 장치에 관한 것이다.The present invention relates to an index table of a machine tool, and more particularly, to an apparatus for rotating an index table in a direct drive method and fixing an angle-divided table to a table with high precision.

선반이나 머시닝센터와 같은 공작기계에서는 공작물의 가공을 위하여 각도분할이 가능한 인덱스테이블을 사용하는 경우가 있다.Machine tools such as lathes and machining centers often use indexable index tables for the machining of workpieces.

종래 각도분할이 가능한 인덱스테이블로는 1° 또는 0.001°까지 고정밀도로 각도분할이 가능한 NC로터리 테이블이 별도의 유니트로 각각 공지된바 있다.Conventionally, an index table capable of dividing the angle is known as a separate unit, NC rotary table capable of high-definition angle division up to 1 ° or 0.001 °, respectively.

도 1에 도시된 인덱스테이블은 1° 내지 5°로 분할이 가능한 구조로서 팔레트(1)와 테이블(2)아래에는 인덱스커플링(3)이 구비되고, 유압라인Ⅰ(4)로 유압이 가해지면 사선으로 표시된 회전체(5)가 상승되면서 인덱스커플링(3)이 베이스(6)와 이탈되면서 테이블(2)이 회전가능한 상태가 되며, 테이블은 모터(7)와 풀리(8) 및 워엄기어(9)에 의하여 회전체의 원주에 형성된 헬리컬기어(10)를 회전시켜 원하는 각도분할이 이루어지면 유압라인Ⅱ(11)로 유압이 가해져 테이블이 다운되면서 테이블의 아래면에 형성된 기어와 인덱스커플링(3)의 접촉면 기어가 치합되면서 테이블이 클램핑된다.The index table shown in FIG. 1 has a structure that can be divided into 1 ° to 5 °. An index coupling 3 is provided below the pallet 1 and the table 2, and hydraulic pressure is applied to the hydraulic line I (4). As the rotary body 5 indicated by the diagonal line is raised, the index coupling 3 is separated from the base 6, and the table 2 is rotatable. The table is provided with a motor 7, a pulley 8, and a worm. When the helical gear 10 formed on the circumference of the rotating body is rotated by the gear 9 to achieve the desired angle division, the hydraulic pressure is applied to the hydraulic line II (11), and the table is down while the gear and the index couple formed on the lower surface of the table. The table is clamped as the contact gears of the ring 3 are engaged.

그러나 상기와 같은 구성은 워엄기어와 헬리컬기어를 구동하기 위하여 정밀한 가공을 요하는 복잡한 구성이 필요하고 워엄기어와 헬리컬기어의 마찰전동으로 구동손실과 마찰열의 발생 및 전동부의 마모 등이 발생하여 정밀도가 저하되며 테이블의 회전속도가 대단히 느려 생산성이 저하되었으며, 도 3에 도시된 또 다른 공지기술인 0.001°까지 분할이 가능한 인덱스테이블은 팔레트(21)와 테이블(22)아래에 회전안내베어링(23)이 구비되며 워엄기어(24)가 워엄휠(25)을 회전시키면 사선부분의 회전체(26)가 회전하면서 각도분할된다.However, the above configuration requires a complicated configuration that requires precise machining in order to drive worm gears and helical gears. The lower the rotational speed of the table, the productivity is lowered, and the index table capable of dividing up to 0.001 °, another known technique shown in FIG. 3, has a rotating guide bearing 23 under the pallet 21 and the table 22. When the worm gear 24 rotates the worm wheel 25 is provided, the rotating body 26 of the diagonal portion is divided by the angle while rotating.

테이블(22)이 임의의 각도로 회전 후 테이블의 클램핑이 필요할 시는 유압라인(27)으로 유압을 공급하여 워엄휠(25)에 조립된 클램핑디스크(28)를 베이스(29)와 밀착시켜 클램핑된다.When the table 22 is rotated at an arbitrary angle and the clamping of the table is required, the hydraulic pressure is supplied to the hydraulic line 27 so that the clamping disk 28 assembled to the worm wheel 25 is brought into close contact with the base 29 for clamping. do.

그러나 상기의 구성 역시 워엄휠과 워엄기어의 마찰전동으로 회전시 구동손실과 마찰열이 발생하여 마모 등에 의하여 정밀도가 저하되고 테이블의 회전속도가 느려 생산성이 저하될 뿐 아니라 1°분할 인덱스테이블과 0.001°분할 인덱스테이블이 각각 구성되어 필요시 교체하여 사용하여야 한다는 문제점이 있었다.However, the above configuration also generates frictional heat between the worm wheel and the worm gear, which causes drive loss and frictional heat, resulting in deterioration of precision due to abrasion. There was a problem in that partitioned index tables were configured separately and used as needed.

본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로 각도분할을 위한 인덱스테이블의 회전을 풀리와 기어 등에 의한 동력전달과정을 배제한 직접 회전방식으로 구동할 수 있게 하는 구성을 제공하는 것을 목적으로 한다.The present invention was developed to solve the above problems, and an object of the present invention is to provide a configuration that allows the rotation of the index table for angular division to be driven by a direct rotation method excluding the power transmission process by pulleys and gears. .

본 발명의 또 다른 목적은 1°분할테이블과 0.001°분할테이블의 기능을 단일화된 인덱스테이블로 선택할 수 있게 하거나 겸용이 가능하게 하는 구성을 제공하는 것이다.It is still another object of the present invention to provide a configuration that allows the function of the 1 ° partition table and the 0.001 ° partition table to be selected as a single index table or to be compatible.

상기한 목적을 위한 본 발명 '직접 구동방식의 인덱스테이블'은 테이블의 주위에 모터스테이터를 형성하고 모터스테이터의 내측에 모터로터를 구비하여 엔코더에 의한 서보제어로 테이블의 회전을 직접 구동할 수 있게 하여 동력전달과정을 생략할 수 있게 구성된다.The present invention 'direct drive index table' for the above purpose is to form a motor stator around the table and having a motor rotor inside the motor stator to directly drive the rotation of the table by servo control by the encoder It is configured to omit the power transmission process.

또한 본 발명은 각도분할된 테이블의 클램핑을 위하여 일측에는 1°~5°분할용 인덱스 클램핑장치를 구비하고 다른 일측에는 0.001°분할용 클램핑장치를 구비하여 각각 독립적인 유압라인으로 제어할 수 있게 하여 하나의 인덱스테이블로 1°~5° 및 0.001°분할용 테이블로 겸용할 수 있게 하거나 하나의 클램핑장치만을 선택하여 구비함으로서 단일의 기능을 갖도록 할 수도 있다.The present invention also provides an index clamping device for dividing 1 ° to 5 ° on one side and a 0.001 ° dividing clamping device on one side so as to be controlled by independent hydraulic lines for clamping the angled table. A single index table can be used as a table for dividing 1 ° to 5 ° and 0.001 ° or a single clamping device can be provided to have a single function.

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

도 5는 본 발명 직접 구동방식의 인덱스테이블의 측단면도이고, 도 6은 본 발명의 0.001°분할기능만을 선택한 테이블의 측단면도이며, 도 7은 본 발명의 1°~5°분할용 기능만을 선택한 측단면도이다.Figure 5 is a side cross-sectional view of the index table of the present invention direct drive method, Figure 6 is a side cross-sectional view of the table selected only the 0.001 ° partition function of the present invention, Figure 7 is selected only for the 1 ° ~ 5 ° partition function of the present invention Side cross section view.

도 5에 도시된 것과 같이 본 발명은 테이블(101)의 회전체(102)에 회전안내베어링(103)을 구비하여 회전체(102)가 자유롭게 회전할 수 있게 구성하고, 회전체(102)의 외주에는 모터로터(105)를 구비하여 베이스(106)에 고정된 모터스테이터(107)에 의하여 회전체(102)가 직접 구동되게 하는 방식인 빌트-인(Built-in)타입으로 구성한다.As shown in FIG. 5, the present invention includes a rotating guide bearing 103 in the rotating body 102 of the table 101 to allow the rotating body 102 to rotate freely, and The outer periphery includes a motor rotor 105 and is built in a built-in type in which the rotating body 102 is directly driven by the motor stator 107 fixed to the base 106.

모터스테이터(107)와 모터로터(105)는 회전체(102)에 구비된 엔코더(108)에 의하여 회전각도가 제어되는 서보모터방식을 채용한다.The motor stator 107 and the motor rotor 105 adopt a servo motor method in which the rotation angle is controlled by the encoder 108 provided in the rotating body 102.

따라서 본 발명에서는 회전체(102)의 회전에 대하여 회전안내베어링(103)이외에는 직접 접촉에 의하여 마찰되는 부분이 없어 마찰열이나 마모가 발생하지 않으며 모터의 회전을 감속하는 부분이 없어 구조가 간단하고 각도분할을 위한 회전을 신속하게 할 수 있다.Therefore, in the present invention, there is no friction part by direct contact with respect to the rotation of the rotating body 102 other than the rotation guide bearing 103, so that no frictional heat or abrasion occurs and there is no part which slows down the rotation of the motor. The rotation for the division can be made quickly.

직접 구동방식에 의하여 임의의 각도로 회전한 회전체(102)는 분할된 각도를 유지하기 위하여 베이스(106)와 회전체(102) 사이에 클램핑장치(109, 110)를 구비한다.The rotating body 102 rotated at an arbitrary angle by the direct driving method includes clamping devices 109 and 110 between the base 106 and the rotating body 102 to maintain the divided angle.

클램핑장치(109, 110)는 1°~5°분할용과 0.001°분할용을 구분하여 각각 설치되며, 1°~5°분할용 클램핑장치(109)는 유압라인Ⅱ(111)에 압유가 공급되면 1°~5°분할용 클램핑장치(109)의 블록a(112)가 아래로 내려가면서 단부에 형성된 기어가 회전체(102)에 고정된 블록c(114)와 베이스(106)에 고정된 블록b(113)의 상 단부분에 형성된 기어(115)를 일치시킨 후 맞물려 회전체(102)를 클램핑한다.The clamping devices 109 and 110 are installed separately for 1 ° to 5 ° splitting and for 0.001 ° splitting, respectively, and the 1 ° to 5 ° splitting clamping device 109 is supplied with hydraulic oil to the hydraulic line II 111. Block a (112) of the 1 ° ~ 5 ° division clamping device 109 is lowered to the block formed in the end of the block c 114 and the block fixed to the base 106 and the gear formed at the end 102 The gear 115 formed at the upper end portion of the b 113 is matched and then engaged to clamp the rotating body 102.

또한 유압라인Ⅰ(116)에 압유가 공급되면 블록a(112)는 상승하면서 블록a, b, c(112, 113, 114)간의 결합이 해제되는 언클램핑 상태가 되어 회전체(102)의 회전을 가능한 상태로 한다.In addition, when the hydraulic oil is supplied to the hydraulic line I (116), the block a (112) ascends and becomes an unclamped state in which the engagement between the blocks a, b, and c (112, 113, 114) is released, thereby rotating the rotating body (102). Make it as possible.

이때 블록c(114)는 회전하고 블록a, b,(112, 113)는 비회전한다.At this time, block c 114 is rotated and blocks a, b, 112, 113 are non-rotated.

또한 1°~5°분할용 클램핑장치(109)는 회전체(102)의 중심축(117)을 기준으로 어느 한쪽에만 구비된다.In addition, the clamping device 109 for splitting 1 ° to 5 ° is provided only on either side of the central axis 117 of the rotating body 102.

0.001°분할용 클램핑장치(110)는 유압라인Ⅲ(118)에 압유가 공급되면 피스톤(119)이 상승하면서 클램핑디스크(120)와 밀착되면서 클램핑되고, 유압라인Ⅲ(118)에 압력이 해제되면 스프링판(121)의 탄력에 의하여 피스톤(119)이 복귀하면서 언클램핑상태가 되어 회전체(102)의 회전을 가능하게 한다.When the clamping device 110 for splitting 0.001 ° is supplied with hydraulic oil to the hydraulic line III 118, the piston 119 is raised while being in close contact with the clamping disk 120, and the pressure is released from the hydraulic line III 118. Due to the elasticity of the spring plate 121, the piston 119 is returned to the state of being unclamped to enable rotation of the rotor 102.

따라서 본 발명에서 구비되는 1°~5°분할용 클램핑장치(109)와 0.001°분할용 클램핑장치(110)는 서로 간섭하지 않도록 각각 분리제어되는 유압라인에 의하여 어느 한쪽만 작동한다.Therefore, the 1 ° to 5 ° splitting clamping device 109 and 0.001 ° splitting clamping device 110 provided in the present invention operate only one of the hydraulic lines that are separately controlled so as not to interfere with each other.

도 6은 0.001°분할용 클램핑장치(110)만을 구비한 본 발명의 또 다른 실시 예이고 도 7은 1°~5°분할용 클램핑장치(109)만을 구비한 본 발명의 또 다른 실시 예이다.6 is another embodiment of the present invention having only a 0.001 ° splitting clamping device 110 and Figure 7 is another embodiment of the present invention having only a clamping device 109 for splitting 1 ° ~ 5 °.

이상에서 설명한 바와 같이 본 발명은 하나의 인덱스테이블로 1°~5°와 0.001°로 분할할 수 있는 용도로 겸용하게 하거나, 각각 사용하게 할 수 있으며 테이블의 회전에 직접 구동방식을 채택하여 구동에 따른 마찰열이나 마모를 방지할 수 있게 하여 신뢰성을 제고할 수 있을 뿐 아니라 테이블의 회전속도를 높여 생산성을 향상하게 할 수 있고 회전체의 구동부를 단순하게 하여 저렴한 비용으로 생산하게 할 수 있게 하는 등 매우 다양한 효과가 있다.As described above, the present invention can be used as a single index table that can be divided into 1 ° to 5 ° and 0.001 °, or can be used separately, and adopts a direct drive method to rotate the table. It is possible to prevent frictional heat and abrasion and to improve reliability as well as to increase productivity by increasing the rotational speed of the table, and to produce at low cost by simplifying the driving part of the rotor. There are various effects.
