본 고안은 공작기계의 공구마모 검출장치에 관한 것으로, 특히 척에 장착된 소재(공작물)에 장애없이 공구마모를 검출할 수 있게 한 공작기계의 공구마모 검출장치에 관한 것이다.The present invention relates to a tool wear detection device of a machine tool, and more particularly, to a tool wear detection device of a machine tool capable of detecting tool wear without disturbing the material (workpiece) mounted on the chuck.

일반적으로 공작기계의 공구는 일정주기로 마모도를 검출함으로써 공구의 교체시기 등을 결정하여 공구교체를 하도록 하는데, 이러한 종래의 공구마모 검출장치를 살펴보면 제1도에서와 같이 베이스(10)의 암프래킷(20)상에 고정된 선단에 검출센서(5)를 갖는 암(30)을 유압에 의해 선회시켜서 선단의 검출센서(S)를 공구에 근방에 위치시키도록 하여 공구의 마모를 검출하도록 한다.In general, the tool of the machine tool determines the replacement time of the tool by detecting wear at regular intervals, and replaces the tool. Referring to the conventional tool wear detection apparatus, as shown in FIG. The arm 30 having the detection sensor 5 at the tip fixed on 20 is pivoted by hydraulic pressure so that the detection sensor S at the tip is positioned near the tool to detect the wear of the tool.

그런데 이러한 종래의 구성은 검출을 위한 세팅시 제1도 (a)에서와 같이 암(30)이 움직이는 과정에서 공작물(40)과 간섭을 일으키기 때문에 공구의 마모측정시에는 반드시 공작물(40)을 공작기계의 척부로부터 빼낸후, 검출작업을 해야만 하는 불편함이 있으며 , 또한 본 검출장치의 조립 및 작동에 관련된 위치반복 정도의 세팅이 힘들어 이에 따른 로스가 발생되었다.However, since the conventional configuration causes interference with the workpiece 40 in the process of moving the arm 30 as shown in FIG. 1A when setting for detection, the workpiece 40 must be machined when measuring the wear of the tool. After removing from the chuck part of the machine, there is an inconvenience of having to perform a detection operation, and also a loss is generated because the setting of the position repetition degree related to the assembly and operation of the present detection device is difficult.

따라서 본 고안에서는 이상과 같은 문제점을 감안하여 헤드스톡부에 고정되는 에어실린더에 의해 직선 왕복운동되는 검출장치를 제공하여 공작물의 장애를 피할 수 있게 하므로써 공작물을 장착한 상태에서도 공구의 마모도를 검출할 수 있으며, 조립 및 작동에 관련된 위치반복 정도의 세팅이 이루어지는 공구마모 검출장치를 제공함에 그 목적이 있다.Accordingly, the present invention provides a detection device that linearly reciprocates by an air cylinder fixed to the headstock in consideration of the above problems, thereby avoiding the obstacle of the workpiece, thereby detecting the wear of the tool even when the workpiece is mounted. It can be, and the object is to provide a tool wear detection device that the setting of the degree of position repetition related to the assembly and operation is made.

상기 목적을 달성하기 위해 본 고안은 공작기계의 헤드스톡부의 베지스 플레이트상에 고정설치되는 에어실린더의 로딩에 따라 출몰되고 하단에 검출센서를 갖는 센서브래킷으로 공구의 마모도를 측정케 한 구성으로 된다.In order to achieve the above object, the present invention is configured to measure the wear level of the tool by a sensor bracket having a detection sensor at the bottom of the air cylinder mounted on the base plate of the headstock of the machine tool. .

이하에서 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

제2도에서와 같이 공작기계의 헤드스톡부(1)에 고정되는 베이스 플레이트(2) 상에는 프론트브래킷(21)과 리어브래킷(22)을 두고, 이 프론트브래킷(21) 상에 고정된 에어실린더(3)와 이를 관통한 로드(31)단에 센서브래킷(4)을 하향설치하여 그 단에 센서(S)를 구비하고, 이 센서브래킷(4) 양측에 고정되고, 프론트브래킷(21)과 리어브래킷(22)에 고정된 가이드 부시(21B,22B)를 관통하여 안내되는 가이드봉(5)을 가진다. 이때, 가이드봉(5) 후단에는 걸림판(51)을 두어 로드의 전진 스트로크를 제한한다. 도면중 설명부호 6은 실린더의 로딩직전에 개방되는 도어이고, 61은 공작물이 물림되는 척을 도시한 것이다.On the base plate 2 fixed to the headstock part 1 of the machine tool as shown in FIG. 2, the front bracket 21 and the rear bracket 22 are provided, and the air cylinder fixed on the front bracket 21 is provided. (3) and the sensor bracket (4) is installed downward at the end of the rod (31) penetrating it and provided with the sensor (S) at the end thereof, and fixed to both sides of the sensor bracket (4), and the front bracket (21) and It has the guide rod 5 guided through the guide bush 21B, 22B fixed to the rear bracket 22. As shown in FIG. At this time, the rear end of the guide rod (5) has a locking plate 51 to limit the forward stroke of the rod. In the figure, reference numeral 6 denotes a door that is opened immediately before loading of the cylinder, and 61 denotes a chuck in which the workpiece is bitten.

이상과 같이 구성된 본 고안의 작동을 살펴보면, 먼저 공구의 마모 상태를 검출시에는 에어실린더(3)의 작동에 따라(이때 도어(6)는 개방된 상태가 된다.) 로드(31)가 전진한다. 이에 따라 제2도 (b)의 가상선과 같이 센서브래킷(4)을 매개로 설치된 센서(S)가 함께 전진하여 도시되지 않은 공구의 끝단 근방에 위치되어 공구의 마모상태를 검출하게 된다.Looking at the operation of the present invention configured as described above, when detecting the wear state of the tool first, the rod 31 is advanced in accordance with the operation of the air cylinder (3) (the door 6 is open). . Accordingly, the sensor S installed through the sensor bracket 4 moves forward together with the virtual line of FIG.

이후, 검출이 완료되면 에어실린더(3)의 작동에 따라 로드(31)가 후퇴하여 최초의 위치로 복귀하게 되고 열렸던 도어(6)는 다시 닫히게 된다. 이에 따라 공구 마모 검출장치는 대기상태에 놓이게 된다. 이에 따라 센서(S) 등의 부품이 보호되고 동시에 에어실린더(3)의 왕복운동에 따라 공구 위치로 접근하는 센서(S)에 의해 공작물과의 장애를 발생시키지 않게 된다.Then, when the detection is completed, the rod 31 is retracted to return to the original position according to the operation of the air cylinder 3, and the door 6 that was opened is closed again. As a result, the tool wear detection device is in a standby state. Accordingly, parts such as the sensor S are protected and at the same time, the sensor S approaching the tool position according to the reciprocating motion of the air cylinder 3 is not caused to cause an obstacle with the workpiece.

한편 로드(31)의 전,후 동작시에 가이드봉(5)은 정확한 직진운동을 안내하는 역할을 하고, 걸림판(51)은 나사결합되거나 세트스크루 등으로 공구위치에 따라 위치고정범위를 달리하여 가이드봉(5)에 착탈할 수 있게 하여 로딩스트로크를 조절 세팅할 수 있게 되는 것이다.On the other hand, the guide rod (5) during the front and rear operation of the rod 31 serves to guide the correct straight movement, the locking plate 51 is screwed or the set screw, etc. different position fixing range depending on the tool position By being able to attach and detach the guide rod (5) is to be able to adjust the setting setting of the loading stroke.

이상과 같이 구성되고 작용되는 본 고안은 공작기계의 척에 공작물의 유,무와 관계없이 공구의 마모검출을 행할 수 있고, 에어실린더에 의한 단순 왕복운동으로 검출스트로크를 가려 공구에 위치되는 반복 위치정도의 세팅이 간단히 이루어지는 효과가 있다.The present invention constructed and operated as described above can detect the wear of the tool regardless of the presence or absence of the workpiece in the chuck of the machine tool, and the position of the repetitive position positioned on the tool by covering the detection stroke by a simple reciprocating motion by the air cylinder. It is effective that the setting of.
