본 발명은 공작기계등에 사용되는 수치제어장치에 관한 것으로, 특히 주연산부와, 각축의 속도 및 위치제어부와, 전원회로를 공유하게 한 각축의 전력증폭부를 하나의 유니트로 일체화시킨 일체형 수치제어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numerical control device used in a machine tool, and more particularly, to an integrated numerical control device in which a main operation unit, a speed and position control unit for each axis, and a power amplifier unit for each axis that share a power supply circuit are integrated into one unit. It is about.

종래의 수치제어장치에 있어서는 수치제어유니트와, 각축 속도 제어유니트와, 주축제어유니트가 각각 별개로 설치되어 있었다.In the conventional numerical control device, the numerical control unit, each axis speed control unit, and the main axis control unit are provided separately.

일예로, NC 선반은 제1도에 도시한 바와같이, 수치제어 유니트(10) 및 X축, Z축 속도제어유니트(20), (30)와, 그 유니트(10, (20), (30)와 독립하여 처리할 장치를 갖는 주축제어유니트(40)로 수치제어장치가 구성되고, 이 수치제어장치의 제어를 받는 X축, Z축, 주축구동모우터(50), (60), (70) 및 그 구동모우터(50), (60), (70)의 구동에 따라 펄스신호를 발생하는 위치검출기(51), (61), (71)로 구성되어 있다.As an example, the NC lathe includes the numerical control unit 10 and the X-axis and Z-axis speed control units 20, 30, and the units 10, 20, 30 as shown in FIG. Numerical control unit is composed of main axis control unit 40 having a device to be processed independently of the control unit, and the X-axis, Z-axis, main axis drive motors 50, 60, ( 70 and position detectors 51, 61, and 71 that generate pulse signals in response to driving of the driving motors 50, 60, and 70.

그러나, 이러한 종래의 장치에 있어서는 수치제어유니트(10)에 X축, Z축위치제어부(12), (13)밖에 설치되어 있지 않으므로 주축의 제어에 대해서는 주축제어유니트(40)로 주축의 위치제어까지 수행하지 않으면 안되고, 또 수치제어유니트(10)의 주연산부(11)에 있어서는 주축의 경우와 각축의 경우로 각각 수치처리방법을 분리하지 않으면 안되는 등 결점이 있었다.However, in such a conventional apparatus, since only the X-axis, Z-axis position control unit 12, and 13 are provided in the numerical control unit 10, the main shaft control unit 40 controls the position of the main shaft for the control of the main shaft. In addition, the main operation unit 11 of the numerical control unit 10 has a drawback in that the numerical processing methods must be separated for the main axis and the respective axis.

또한, 각각의 유니트(10, 20, 30, 40)가 개별로 설계되어 있으므로 수치제어유니트(10)와 각축제어유니트(20, 30, 40)를 접속하는 인터페이스회로 및 콘넥터, 케이블등이 필요하고, 각축제어유니트(20, 30, 40)에 전원회로(22, 32, 42)가 각각 필요하며, 또 수치제어장치내의 각 유니트(10, 20, 30, 40)가 독립적으로 설계되어 있으므로 그 각 유니트들이 준비상태에 있지 않으면 안되고 구조가 복잡하게 되는 결점이 있었다.In addition, since each unit 10, 20, 30, 40 is individually designed, an interface circuit, a connector, a cable, etc. for connecting the numerical control unit 10 and each axis control unit 20, 30, 40 are necessary. The power supply circuits 22, 32, and 42 are required for each axis control unit 20, 30, and 40, and each unit 10, 20, 30, 40 in the numerical control device is designed independently. The drawback was that the units had to be ready and the structure was complicated.

본 발명은 이러한 점을 감안하여, 각축의 위치제어 및 속도제어를 중앙연산부에서 디지탈신호로 제어함으로써 주축도 각축과 같은 방식으로 제어할 수 있고, 주연산부 및 각축의 속도, 위치제어부, 전력증폭부를 하나의 유니트로 통합함으로써 종래의 장체에서 각 유니트 사이의 접속에 필요했던 인터페이스회로, 콘넥터, 케이블등이 불필요하고, 전력증폭부에서 하나의 전원회로만을 공유하여, 수치제어장치의 구조가 간단하게 되고, 제품의 신뢰성이 향상되며, 저가격화를 꾀할 수 있게 창안한 것으로, 이를 첨부된 본 발명의 도면을 참조하여 상세히 설명하면 다음과 같다.In view of the above, the present invention can control the main axis in the same manner as each axis by controlling the position control and the speed control of each axis by a digital signal from the central computing unit, and the speed, position control unit, and power amplification unit of the main operation unit and each axis. Integrating into one unit eliminates the need for interface circuits, connectors, and cables required for connection between units in conventional devices, and the structure of the numerical control device is simplified by sharing only one power supply circuit in the power amplifier. In order to improve the reliability of the product and to reduce the price, the invention is described in detail with reference to the accompanying drawings of the present invention.

제2도는 NC 선반에 적용되는 본 발명의 일체형 수치제어장치 블록도로서 이에 도시한 바와같이, 주축과 X축, Z축을 동일하게 수치처리하는 주연산부(100)과, X축, Z축, 주축의 속도 및 위치제어를 행하는 X축, Z축, 주축제어부(210), (220), (230)를 상기 주연산부(100)와 다중 프로세서 시스템으로 구성한 각축제어부(200)와, 전원회로(340)를 공유하고 상기 각축제어부(200)의 X축, Z축, 주축제어부(210), (220), (230)의 출력신호에 의하여 X축, Z축, 주축구동모우터(500), (600), (700)의 구동을 제어하는 X축, Z축, 주축전력증폭부(310), (320), (330)로된 전력중폭부(300)를 일체화시켜 수치제어장치(400)를 구성하고, 상기 X축, Z축, 주축구동모우터(500), (600), (700)의 구동에 따라 위치검출기 (510),(610), (710)에서 발생된 펄스신호가 상기 각축제어부(200)의 X축, Z축, 주축제어부(210), (220), (230)에 인가되게 구성한 것으로, 이와같이 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.2 is a block diagram of the integrated numerical control device of the present invention applied to an NC lathe, as shown in FIG. And the power circuit 340 of each of the X-axis, Z-axis, main axis controllers 210, 220, and 230 for the speed and position control of the main controller 100 and the multiprocessor system. ) X-axis, Z-axis, main axis driving motor 500, (according to the output signal of the X-axis, Z-axis, main axis control unit 210, 220, 230 of each axis control unit 200, ( The numerical control device 400 is integrated by integrating the power amplification part 300 including the X, Z, and main power amplification parts 310, 320, and 330 for controlling the driving of 600 and 700. And pulse signals generated by the position detectors 510, 610, and 710 according to the driving of the X, Z, and main axis driving motors 500, 600, and 700.

주연산부(100)인 주중앙처리장치(CPU)와 각축제어부(200)의 X축, Z축, 주축제어부(210), (220), (230)인 X, Z축용중앙처리장치와 주축용중앙처리장치에 있어서 주중앙처리장치와 X, Z축용 중앙처리장치, 주중앙처리장치와 주축용중앙처리장치 사이에 정보 데이타를 주고받는 것은 다중 프로세서 시스템방식으로 공통메모리(RAM)를 이용하여 수행하면 된다.X-axis, Z-axis, main axis controller 210, (220), (230) of the central processing unit (CPU) and the main axis processing unit (200), the main computing unit 100, In the central processing unit, the exchange of information data between the main central processing unit, the central processing unit for the X and Z axes, the main central processing unit and the central processing unit for the main axis is performed using a common memory (RAM) as a multiprocessor system. Just do it.

그리고, 각축제어부(200)의 X축제어부(210)의 출력신호는 전력증폭부(310)의 X축전력증폭부(310)에 입력되고, 마찬가지로, Z축제어부(220) 및 주축제어부(230)의 출력신호는 Z축 전력증폭부(320) 및 주축전력증폭부(330)에 각각 입력되며, 또한, 이때 3상교류전원을 입력하는 전원회로(340)의 출력전압이 X축, Z축, 주축전력증폭부 (310), (320), (330)에 공통인가된다.The output signal of the X-axis controller 210 of each axis controller 200 is input to the X-axis power amplifier 310 of the power amplifier 310, and similarly, the Z-axis controller 220 and the main axis controller 230. ) Is input to the Z-axis power amplifier 320 and the main power amplifier 330, respectively, and at this time, the output voltage of the power circuit 340 for inputting the three-phase AC power is X-axis, Z-axis In addition, the main power amplifiers 310, 320, 330 are applied in common.

이에따라, 상기 각축제어부(200)의 X축, Z축, 주축제어부(210), (220), (230)에서 각각 출력하여 전력증폭부(300)의 X축, Z축, 주축전력증폭부(310), (320), (330)에 각각 입력된 신호는 증폭되어 X축, Z축, 주축구동모우터(500), (600), (700)에 구동전력으로 인가되므로 그 각축구동모우터(500),(600), (700)는 구동된다. 이와같이 X축, Z축, 주축구동모우터(500), (600), (700)가 구동됨에 따라 위치검출기(510), (610), (710)에서 각각 펄스신호가 발생되어 각축제어부(200)의 X축, Z축, 주축제어부(210), (220), (230)에 위치검출신호로 인가된다.Accordingly, the X-axis, Z-axis, the main axis control unit 210, 220, 230 of the respective axis control unit 200 is output by the X-axis, Z-axis, main axis power amplifier of the power amplifier 300 ( Signals respectively input to 310, 320, and 330 are amplified and applied as driving power to the X, Z, and main shaft driving motors 500, 600, and 700, respectively. 500, 600, and 700 are driven. As the X, Z, and main axis driving motors 500, 600, and 700 are driven as described above, pulse signals are generated from the position detectors 510, 610, and 710, respectively, to control the respective axes. ) Is applied as a position detection signal to the X-axis, Z-axis, the main axis control unit 210, 220, 230.

이상에서 주축과 X축, Z축이 있는 경우에 대해서 설명하였지만 각축과 주축의 수가 증가된 경우에는 상기와 동일한 방식으로 구성하면 된다.The case where there is a main axis, an X axis, and a Z axis has been described above. However, when the number of each axis and the main axis is increased, the configuration may be performed in the same manner as described above.

이상에서와 같이 동작되는 본 발명은 각축 및 주축의 위치, 속도제어를 디지탈신호로 공통제어하기 때문에 부품수 및 소비전력이 절감됨은 물론, 노이즈의 제거 및 정밀도의 향상이 용이하게 되고, 전원전압 및 온도 변화의 영향을 받지 않게되어 고신뢰성을 얻을 수 있게 된다.The present invention operated as described above, the common control of the position and speed control of each axis and the main axis with a digital signal, as well as the number of parts and power consumption is reduced, as well as the noise is removed and the accuracy is improved, It is not affected by temperature changes and high reliability can be obtained.

또한, 종래의 수치제어장치에 있어서는 각 유니트로 이상검출 및 표시를 행하고, 주연산부에 어느 유니트에서 이상이 발생되었는가의 정보를 알려줄 수 밖에 없으므로, 표시 장치(CRT)등에 이상검출을 직접 표시하고자 하는 경우에는 별도의 특수한 회로가 필요하기 되었다. 그러나, 본 발명에 있어서는 주연산부에서 모든 제어부를 동일방식으로 제어하게 되므로 표시장치등에 이상검출을 직접 표시하고자 하는 경우에는 특수한 회로가 필요없이 주연산부의 집중관리에 의해 용이하게, 수행할 수 있게 된다.In addition, in the conventional numerical control apparatus, abnormal detection and display are performed on each unit, and the main operation unit has to inform the unit operation of information on which unit has an abnormality. Therefore, it is desired to directly display abnormal detection on the display device (CRT). In that case, a special circuit was required. However, in the present invention, since all the control units are controlled by the main operation unit in the same manner, when an abnormal detection is directly displayed on the display device or the like, it is possible to easily perform the central operation unit by intensive management without requiring a special circuit. .

또한, 본 발명의 수치제어장치는 하나의 유니트로 일체화되므로 구조가 간단해지고, 원가가 절감되며 제품의 신뢰성이 향상되는 효과가 있다.In addition, since the numerical control device of the present invention is integrated into one unit, the structure is simplified, the cost is reduced, and the reliability of the product is improved.
