본 고안은 공작기계의 공작물 가공중에 발생하는 공구의 파손을 광소자가 감지하여 공구의 파손을 인식하여 공작기계의 비절삭시간을 단축시키는 공작기계의 공구파손 감지장치에 관한 것이다.The present invention relates to a tool breakage detection device of a machine tool to reduce the non-cutting time of the machine tool by detecting the breakage of the tool by the optical device to detect the breakage of the tool generated during the workpiece machining of the machine tool.
일반적으로 공작기계의 절삭이나 가공등의 작동중에 무리한 부하가 걸리거나 공구가 파손되면, 필요없이 공작기계가 동작을 하게 되거나 공구의 파손을 인식하지 못하여 가공할 공작물에 손실을 가져오거나 절삭시간이 길어지게 된다.In general, if an excessive load is applied or a tool is damaged during cutting or machining of a machine tool, the machine tool may be operated without any need or the tool may not be recognized, resulting in loss of the workpiece to be processed or a long cutting time. You lose.
종래의 경우에 있어서는 상기의 공구파손등을 감지하기 위하여, 리미트스위치를 구성하여 공작물 가공후에 공구를 리미트스위치에 전진시켜 공작기계의 내부연산기능을 이용하여 공구의 길이를 검사하고 공구의 파손여부를 감지함으로써 실제 공작물의 가공시간이 필요이상 길어지게 된다. 또한, 공작기계의 스핀들의 전류를 감지하여 공구의 파손시에 과부하를 감지하여 공구의 파손여부를 진단함으로써 공작기계내에 전류감지를 위한 감지기능과 매크로(Macro:내부기계어)기능을 이용함으로 복잡하고 불편한 점이 있었다.In the conventional case, in order to detect the above-mentioned tool breakage, the limit switch is configured to advance the tool to the limit switch after the workpiece is processed, and the tool length is inspected using the internal computing function of the machine tool, and the tool is damaged or not. By sensing, the machining time of the actual workpiece is longer than necessary. In addition, it detects the current of the spindle of the machine tool, detects the overload when the tool breaks, diagnoses the damage of the tool, and uses the detection function and the macro function to detect the current in the machine tool. There was an inconvenience.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로 광소자를 공구의 일측에 부착하여 공구의 파손을 감지하므로써 공작기계의 실사용시간을 단축시킨 것으로 구성을 살펴보면 다음과 같다.The present invention has been made in view of the above problems, and the optical device is attached to one side of the tool to detect breakage of the tool, thereby reducing the actual operating time of the machine tool.
공작기계의 공구파손을 감지하기 위하여 공구(7)의 일측에 취부되어 발광부(11a)와 수광부(11b)가 형성되어 공구(7)의 파손여부를 감지하는 광소자(10)와, 수광부(11b)의 작동으로 구동하여 릴레이(RL)를 구동시키는 다수개의 트랜지스터(TR1)(TR2)를 구성한 신호처리회로부(30)와, 릴레이(RL)접점의 '온/오프'에 따라 작동하고 공구(7)의 파손상태를 감시하는 리미트스위치(LS)(23)가 일측에 구성된 실린더부(20)를 구비하였다.In order to detect a tool breakage of a machine tool, a light emitting unit 11a and a light receiving unit 11b are formed at one side of the tool 7 to detect whether the tool 7 is damaged and the light receiving unit ( The signal processing circuit section 30 comprising a plurality of transistors TR1 and TR2 which are driven by the operation of 11b) to drive the relay RL, and operate according to the 'on / off' of the relay RL contact and The limit switch (LS) 23 which monitors the damage | damage state of 7) was provided with the cylinder part 20 comprised in one side.
이하 본 고안의 작용상태를 상세히 설명하면 다음과 같다.Hereinafter will be described in detail the working state of the present invention.
제1도는 본 고안의 구성도로 공작기계의 주축(5)에 공구(7)를 장착하여 공작물(9)을 가공하는 데 공구(7)의 일측에 발광부(11a)와 수광부(11b)가 형성된 광소자(10)를 취부하여 공구(7)가 파손될 경우에 광소자(10)가 이를 감지하여 실린더부(20)를 통해 신호처리회로부(30)에 감지신호를 보낸다. 입력된 감지신호는 현재의 릴레이(RL)접점상태를 바꾸어 리미트스위치(23)를 구동하여 공작기계에 스킵(skip)신호를 보내어 공구(7)의 파손여부를 인식시키고 공작기계의 동작을 중지시킨다.1 is a configuration of the present invention to mount the tool (7) to the main shaft (5) of the machine tool to process the workpiece 9, the light emitting portion (11a) and the light receiving portion (11b) formed on one side of the tool (7) When the optical device 10 is mounted and the tool 7 is broken, the optical device 10 detects this and sends a detection signal to the signal processing circuit unit 30 through the cylinder unit 20. The input detection signal changes the current relay (RL) contact state to drive the limit switch 23 to send a skip signal to the machine tool to recognize whether the tool 7 is damaged and to stop the operation of the machine tool. .
제2도는 본 고안의 블록도를 도시한 것으로 공작물(9)을 가공중인 공구(5)의 일측에 발광부(11a)와 수광부(11b)로 형성된 광소자(10)의 감지신호에 의하여 신호처리회로부(30)의 트랜지스터(TR1)(TR2)의 구동은 릴레이(RL)를 작동시켜 공작기계회로부(40)에 입력한다.2 is a block diagram of the present invention, and the signal processing is performed by the detection signal of the optical element 10 formed of the light emitting portion 11a and the light receiving portion 11b on one side of the tool 5 processing the workpiece 9. The driving of the transistors TR1 and TR2 of the circuit part 30 operates the relay RL and inputs it to the machine tool circuit part 40.
제3도는 본 고안의 일 실시예로 도시한 신호처리회로부(30)로 포토인터럽터(PI)의 발광부(11a)와 수광부(11b)사이에 빛의 통과를 막는 공구(7)가 있을 경우에는 수광부(11)의 트랜지스터(TR1)에 전류가 흐르지 않으므로 트랜지스터(TR1)는 '오프'된다. 트랜지스터(TR1)가 '오프'된 상태에서는 트랜지스터(TR1)의 콜렉터측의 전압이 트랜지스터(TR2)에 걸리므로 트랜지스터(TR2)가 도통이 되어 릴레이(RL)는 '온'상태가 된다.3 is a signal processing circuit part 30 as an embodiment of the present invention, when there is a tool 7 that prevents light from passing between the light emitting part 11a and the light receiving part 11b of the photointerrupter PI. Since no current flows in the transistor TR1 of the light receiving unit 11, the transistor TR1 is 'off'. In the state in which the transistor TR1 is 'off', the voltage on the collector side of the transistor TR1 is applied to the transistor TR2, so that the transistor TR2 becomes conductive, and the relay RL is in an 'on' state.
광소자(10)의 발광부(11a)와 수광부(11b)의 상태는 가공중인 공구(7)가 있는 정상상태이므로 릴레이(RL)의 접점이 공작기계회로부(40)의 스킵으로 입력되므로 공작기계는 현재실행중인 블록을 계속 진행한다.Since the state of the light emitting portion 11a and the light receiving portion 11b of the optical element 10 is a normal state in which the tool 7 is being processed, the contact of the relay RL is inputted as a skip of the machine tool circuit portion 40, thereby causing the machine tool to be machined. Continues the currently running block.
가공중인 공구(7)가 부러져 파손되면, 포토인터럽터(PI)의 수광부(11b)에 접속된 트랜지스터(TR1)의 베이스측에 전류가 흐르게 되어 트랜지스터가 도통상태가 된다. 그러므로 트랜지스터(TR2)의 베이스에 전류가 걸리지 않게 되므로 트랜지스터(TR2)는 '오프'되어 릴레이(RL)접점이 '오프'상태가 된다. 따라서, 공작기계회로부(40)의 스킵입력으로는 '온'신호가 입력되므로 현재실행중인 가공 프로그램의 블록을 건너뛰고 다음블록을 실행하게 된다.When the tool 7 which is being processed is broken and broken, current flows to the base side of the transistor TR1 connected to the light receiving portion 11b of the photointerrupter PI, and the transistor is in a conductive state. Therefore, since the current is not applied to the base of the transistor TR2, the transistor TR2 is 'off' so that the relay RL contact becomes 'off'. Therefore, since the 'on' signal is input to the skip input of the machine tool circuit unit 40, the next block is skipped and the next block is skipped.
또한 실린더부(20)전진단의 리미트스위치(23)는 포토인터럽터(PI)가 공구파손을 감시하는 상태인지를 알려주기 위한 것이다. 즉, 실린더부(20)가 후퇴했을 때에는 공구(7)의 파손여부를 감시하지 않는 경우이므로 이 때에는 수광부(11)의 트랜지스터(TR1)가 '온'되어 릴레이(RL)가 '오프'상태에서도 스킵신호를 처리하지 않는다.In addition, the limit switch 23 of the forward end of the cylinder portion 20 is for indicating whether the photo interrupter PI monitors the tool breakage. That is, when the cylinder 20 is retracted, the tool 7 is not monitored for damage. In this case, even when the transistor TR1 of the light receiver 11 is 'on' and the relay RL is 'off', Do not process skip signal.
본 고안은 광소자(10)를 이용하여 공작기계의 공구(7)파손여부를 인식함으로써 절삭시간을 단축시켜 공작기계 사용에 편리함을 제공하기 위한 것이다.The present invention is to provide a convenience in using a machine tool by reducing the cutting time by recognizing whether the tool (7) of the machine tool is broken by using the optical device (10).
