본 고안은 공작기계의 콜리트척의 기준면에 공작물이 밀착 상태를 공기압으로서 확인하여, 공작물의 척킹상태를 확인하도록 구성한 공작기계용 콜리트척의 공작물 밀착상태와 인장장치에 관한 것으로서, 연삭기나 선반등 기타 공작기계에 주축대에 형성된 척에 공작물을 자동으로 척킹할 경우 공작물의 밀착상태를 공기압으로 확인하므로서, 통상적으로 공작물이 척내면에 정확하게 밀착되지 않고 기울어진 상태로 척킹되어 가공됨으로서 유발되는 가공불량을 미연에 방지하여 가공불량률을 감소하고, 이로인한 원가를 절감함에 그 목적이 있다.The present invention relates to a workpiece adhesion state and a tensioning device of a collet chuck for a machine tool configured to check the state of adhesion of a workpiece to the reference surface of the collet chuck of a machine tool by checking the pneumatic pressure. When the workpiece is automatically chucked to the chuck formed on the main shaft of the machine tool, the adhesion state of the workpiece is checked by pneumatic pressure. Thus, the machining defect caused by the workpiece being chucked in an inclined state rather than being closely adhered to the inner surface of the chuck is processed. It aims to reduce the processing defect rate by preventing it and reduce the cost.
종래의 공작기계의 척은 단순히 물품을 고정하게만 되어있기 때문에, 공작물이 척에 제대로 척킹되었는지 아니면 한쪽으로 기울어져서 고정이 되었는지 확인하기 위하여서는, 별도의 측정기구인 다이알게이지나 센터게이지를 사용하여 측정하였는바, 이는 공작물의 고정상태 확인에 많은 시간이 소요되고 작업에 불편을 주기 때문에, 동일 모델의 공작물을 다량 가공하는 자동화 라인에서는 측정게이지에 의한 공작물 고정상태 확인은 거의 하지않고 작업자의 숙련에 의하여 눈으로 측정하여 공작물을 가동하였기 때문에 특히, 마무리 작업인 그라인더 작업에서 1차 가공시 발생한 칩이 공작물에 묻은 상태로 고정되면서, 공작물이 편심으로 가공되어 제품의 가공불량이 발생되는 예가 허다한 현실정이었다.Since a conventional machine tool chuck simply fixes an article, a separate measuring instrument, a die gauge or a center gauge, is used to check whether the workpiece is properly chucked to the chuck or tilted to one side. Since this takes a lot of time and inconvenience in checking the fixed state of the workpiece, in the automated line that processes a large number of workpieces of the same model, the fixed state of the workpiece is hardly checked by the measuring gauge, Since the workpiece was operated by visual measurement, in particular, in the grinder work, which is a finishing work, the chips generated during the first machining were fixed in the state of being stuck to the work, and the work was eccentrically processed, resulting in many cases of product defects. .
본 고안은 이와같은 종래의 제결함을 감안하여 공작기계의 주축대 일측에 콤프레샤와 연결된 공기호스를 갖는 하우징을 설하여 고압의 공기를 척의 공작물 밀착면인 기준면에 형성한 감지공으로 전달함으로서 공작물의 밀착상태를 확인토록 한, 공작기계용 콜리트척의 공작물 밀착상태 확인 장치에 관한것으로서, 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention, in view of such conventional defects, installs a housing having an air hose connected to the compressor on one side of the main shaft of the machine tool, and delivers high-pressure air to the sensing hole formed on the reference surface, which is the contact surface of the workpiece of the chuck, to close the workpiece. Regarding the state of contact between the workpiece contact state of the collet chuck for the machine tool to check the state, it will be described in detail based on the accompanying drawings.
주축대(1) 후단에 설한 척실린더(2)에 의하여 주축(3)내로 장설된 스핀들(4)이 전, 후진하면서 이와 연동되는 콜릿(6)이 작동하여 척(5)에 공작물을 척킹하는 공작기계에 있어서, 상기 주축대(1)와 척실린더(2)사이에 콤프레샤와 연결된 공기호스(8)가 결착된 하우징(7)을 설하고 상기 공기호스(8)와 연통토록 주축(3)에 형성한통공(3')이 주축(3)과 스핀들(4)사이의 유로(4')와 스핀들(4)내부에 형성한 유로(4')가 연통되어 척(5)의 공작물 밀착면에 형성한 감지공(5')으로 공기압을 공급하여, 공작물의 밀착상태를 확인하므로서 척킹상태를 확인하는 것으로, 미설명부호 9는 공작물, 10은 공작물을 척(5)에 공급하는 자동레바이며, 11은 공작물을 가공하는 그라인더이며, 12는 척실린더 장착용 플랜지이고 13은 주축회전용 휠이며, 14는 전동밸트, 15는 베어링, 16은 기밀용 링이며, 23은 척을 고정하는 면판이다.The collet 6 interlocked with the chuck cylinder 2 installed at the rear end of the main shaft 1 in the main shaft 3 is moved forward and backward to chuck the workpiece on the chuck 5. In a machine tool, a housing (7) in which an air hose (8) connected to a compressor is installed between the headstock (1) and the chuck cylinder (2) is installed and the main shaft (3) communicates with the air hose (8). The through hole 3 'formed in the flow path 4' between the main shaft 3 and the spindle 4 and the flow path 4 'formed inside the spindle 4 communicate with each other so that the workpiece contact surface of the chuck 5 is connected. By supplying air pressure to the sensing hole (5 ') formed in the check to check the chucking state by confirming the state of contact of the workpiece, reference numeral 9 is a workpiece, 10 is an automatic lever for supplying the workpiece to the chuck (5). , 11 is a grinder for processing a workpiece, 12 is a flange for mounting a chuck cylinder, 13 is a wheel for turning a spindle, 14 is an electric belt, 15 is a bearing, 16 is an airtight And, 23 is a surface plate for fixing the chuck.
이와같이 구성된 본 고안의 작용효과를 설명하면, 자동레바에 의하여 공작물을 척(5)에 밀착하고 척실린더(2)를 작동시켜 콜릿(6)으로 공작물을 고정한후 콤프레샤에서 공기호스(8)를 통하여 전달되는 고압의 공기를 통공(3')과 유로(4')를 통하여 척(5)의 감지공(5')으로 전달하면, 공작물과 척(5)사이에 칩이 들어가는 등, 기타 이유로 인하여 공작물의 밀착상태가 불량이면 감지공(5')으로 전달하면, 공작물과 척(5)사이에 칩이 들어가는 등, 기타 이유로 인하여 공작물의 밀착상태가 불량이면 감지공(5')으로 부터 공기가 새어나가게 되고, 공작물의 밀착된 상태가 양호하면 공기가 새어나가지않게 되어서, 공작물의 밀착상태를 측정하므로서 척킹상태를 측정토록하는 것으로, 이때, 공작물의 밀착상태가 불량이면 자동레바로 공작물을 잡은 상태에서 척실린더(2)를 작동시켜 콜릿(6)이 공작물을 이완토록하여, 주축(3)을 2-3회 회전시켜서 공작물에 붙은 칩을 떼어내거나 잘못 고정된 것을 바로잡아 다시 밀착고정하고 유압을 전달하여 이상이 없으면 가공토록 하는 것이다.Referring to the effect of the present invention configured as described above, the workpiece is held in close contact with the chuck (5) by the automatic lever and the chuck cylinder (2) to fix the workpiece with the collet (6) through the air hose (8) in the compressor When the high pressure air transmitted is transferred to the sensing hole 5 'of the chuck 5 through the through hole 3' and the flow path 4 ', the chip enters between the workpiece and the chuck 5 for other reasons. If the contact state of the workpiece is poor, if it is delivered to the sensing hole 5 ', the chip enters between the workpiece and the chuck 5, and for other reasons, if the contact state of the workpiece is poor, air from the sensing hole 5' When leaking, if the tight state of the workpiece is good, the air does not leak, and the chucking state is measured by measuring the close state of the workpiece. In this case, if the close state of the workpiece is poor, the workpiece is held by the automatic lever. Chucksilin (2) to allow the collet 6 to relax the workpiece, and rotate the spindle 3 or 2 times to remove the chip attached to the workpiece or to correct the incorrectly fixed to fix again and deliver the hydraulic pressure If it is not there, it is processed.
상기한 바와같이 본 고안은 콤프레샤에서 발생한 고압의 공기를 공기호스를 통하여 척(5)의 감지공에 전달하여 공작물의 밀착상태를 확인하여 작업토록 함으로서, 별도의 측정기기로 공작물을 고정상태를 측정할 필요가 없어서 측정에 소요되는 시간을 절감하고 공작물이 잘못 고정되어서 발생하는 가공불량을 없애주었기 때문에, 생산원가가 절감되는 등 그 실사용 가치를 일층 고양시킨 신규유용의 고안이다.As described above, the present invention transmits the high pressure air generated by the compressor to the sensing hole of the chuck 5 through the air hose to check the work state of the work, thereby measuring the work state by using a separate measuring device. It saves time for measurement because it does not need to be done, and eliminates processing defects caused by incorrectly fixing the workpiece, thus reducing the cost of production.
