Description

CNC선반의 가공물회수장치Workpiece collection device of CNC lathe

본 발명은 CNC선반의 가공물회수장치에 관한 것으로, 특히 대향형 2주축을 갖는 선반에서 공작물 회수를 용이하게 한 CNC선반의 가공물회수장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workpiece recovery apparatus for CNC lathes, and more particularly, to a workpiece recovery apparatus for CNC lathes that facilitates workpiece recovery on a lathe having opposite two spindles.

종래에는 파트 캐처(PARTS CATCHER)를 사용하여 주축안에서 밖으로 공작물을 밀어내어 낙하시키고 이를 이동하는 버킷 등에 담아 배출하거나, 오토 로더(AUTO LOADER)장치 등을 사용하여 공작물을 공급하거나 및 배출하는 방법을 사용하였다.Conventionally, a part catcher pushes a workpiece out of the main shaft and drops it and puts it in a moving bucket. It was.

전자와 후자의 경우 공작물의 크기 특히 길이에 관하여는 버킷의 용량에 제한을 받아 장축의 가공공작물에는 사용이 불가능하였다. 더욱이 후자의 경우 비교적 다양한 공작물을 안정되게 공급 및 배출할 수 있으나 사이클 타임 및 경제성에 제약을 받을 수밖에 없는 단점이 있다.In the former and latter cases, the size of the workpiece, in particular its length, was limited by the capacity of the bucket, making it impossible to use on long axis workpieces. Moreover, the latter can stably supply and discharge a relatively wide variety of workpieces, but has a disadvantage in that cycle time and economical efficiency are limited.

따라서 본 발명은 기계본체 내에 있는 각종 기능을 충분히 이용함으로써 경제성을 실현하고 특히 장축가공에 별도의 복잡한 장치없이 가이드 튜브를 주축안에 삽입, 밀어내기 식으로 공작물을 배출토록 하여 공간 제약을 받지 않으며 사이클 타임면에서 가공준비 시간을 최소화시킨 CNC선반의 가공물회수장치를 제공함에 그 목적이 있다.Therefore, the present invention realizes economic feasibility by fully utilizing various functions in the machine body, and in particular, the workpiece is discharged by inserting and pushing the guide tube into the main shaft without any complicated device for long-axis machining, and is not restricted in space. The purpose is to provide a workpiece recovery device for CNC lathes that minimizes the preparation time for processing.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은, 대향형 주축을 가지고 있는 선반에 있어서, 어느 한쪽의 축이송 기능을 갖는 제 2주축의 내부에 가공완료된 공작물을 안내하는 가이드튜브를 삽입 고정하여 다른 한쪽의 제 1주축에 물려진 공작물이 상기 제 2주축의 이송에 의해 가공된 공작물을 상기 가이드튜브의 후방으로 밀어내어 공작물의 회수를 가능하도록 한 것을 특징으로 한다.Specific means of the present invention for achieving the above object, in the lathe having an opposite spindle, by inserting and fixing a guide tube for guiding the finished workpiece inside the second spindle having one of the axis feed function It is characterized in that the workpiece bited by the other first spindle pushes the workpiece processed by the transfer of the second spindle to the rear of the guide tube to enable the recovery of the workpiece.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

도 1에 도시된 바와 같이 대향형 주축(10,12)을 가지고 있는 선반에 있어서, 어느 한쪽의 축이송 기능을 갖는 제 2주축(12)의 내부에 가공완료된 공작물을 안내하는 가이드튜브(14)가 삽입되어 상기 제 2주축(12)의 후방에 설치된 튜브브래킷(16)에 지지되어 있고 동시에 가이드 튜브(14)는 튜브브래킷(16)측에 고정된 튜브클램퍼(18)에 의해 고정되어 있다.A guide tube 14 for guiding a finished work in the interior of a second spindle 12 having either of the axis feed functions in a lathe having opposite spindles 10 and 12 as shown in FIG. Is inserted and supported by the tube bracket 16 provided at the rear of the second spindle 12, and at the same time, the guide tube 14 is fixed by the tube clamper 18 fixed to the tube bracket 16 side.

그리고 상기 가이드 튜브(14)의 후방에 이 가이드튜브(14)를 통하여 배출되는 공작물을 받이하는 경사판(20)이 구비되어 있다.And the rear of the guide tube 14 is provided with an inclined plate 20 for receiving the workpiece discharged through the guide tube (14).

도면중 미설명부호 21,22는 척이다.In the drawings, reference numerals 21 and 22 are chucks.

이와 같이 구성된 본 실시예의 작동상태를 설명한다.The operating state of this embodiment configured as described above will be described.

도 1에서와 같이 양방의 주축(10,12)측 척(21,22)에 클램핑된 공작물(P1,P2)을 각각의 공구(T1,T2)로 가공하여 완료가 되면 도 2에서와 같이 우측 제 2주축(12)의 척(22)이 언클램핑 상태가 되고 제 2주축(12)이 대향된 주축(10)측으로 프로그램에 의해 이동하게 된다.As shown in FIG. 1, the workpieces P1 and P2 clamped to the chucks 21 and 22 on both main shafts 10 and 12 are machined with the respective tools T1 and T2 to be completed. The chuck 22 of the second spindle 12 is in an unclamped state and the second spindle 12 is moved by a program to the opposite main shaft 10 side.

이에 의해 우측의 가공된 공작물(P2)이 대향된 주축(10)의 척(21)에 물려있는 공작물(P1)의 선단면에 접촉하는 순간부터 후방으로 밀려서 척(22)으로부터 이탈됨과 동시에 가이드튜브(14)내에 놓여지게 되고 또, 척(21)에 고정된 공작물(P1)의 우측단은 대향된 척(22)에 장입되어 클램핑된다.As a result, the processed workpiece P2 on the right side is pushed backward from the moment when it comes into contact with the distal end surface of the workpiece P1 held by the chuck 21 of the opposing spindle 10, and is separated from the chuck 22, and at the same time, the guide tube. The right end of the work piece P1, which is placed in the 14 and fixed to the chuck 21, is charged to the opposing chuck 22 and clamped.

이같이 척(22)에 가공된 공작물(P2)이 탈거되고 상대편 공작물(P1)을 클램핑한 상태가 되면 좌측의 주축(10)쪽 척(21)이 언클램프가 된다.In this way, when the workpiece P2 processed on the chuck 22 is removed and the other workpiece P1 is clamped, the chuck 21 on the left side of the main shaft 10 becomes unclamped.

이후 도 3에서와 같이 제 2주축(12)이 다시 우측으로 이동하면 우측의 척(22)에 물려진 공작물(P1)은 좌측의 주축(10)에서 우측으로 소정량 빠져나오게 된다.Afterwards, as shown in FIG. 3, when the second main shaft 12 is moved to the right again, the workpiece P1 bitten by the chuck 22 on the right side exits a predetermined amount from the main shaft 10 on the left side to the right side.

이같은 상태에서 좌측의 척(21)을 클램핑 한 상태로 한 후 도 4에서와 같이 공구(T3)를 이용하여 공작물(P1)을 절단하게 되고, 다시 우측의 주축(12)을 후방으로 이동시키게 되면 도 5에서와 같이 대향된 공작물 가공준비 상태가 된다.In such a state, after clamping the chuck 21 on the left side, the workpiece P1 is cut using the tool T3 as shown in FIG. 4, and the main spindle 12 on the right side is moved backward. As shown in FIG. 5, the opposing workpiece is ready for processing.

상기와 같은 작동은 프로그램에 의해 순차적으로 진행되는 것으로, 좌측으로부터 공급되는 공작물을 소정량의 길이로 절단하여 연속작업을 수행하게 된다.As described above, the operation is sequentially performed by a program, and the work supplied from the left side is cut into a predetermined amount of length to perform a continuous operation.

이같이 2개의 대향된 주축(10,12)중 어느 한쪽을 이송시켜 상대편 주축(12)의 가이드튜브(14) 후방으로 절단된 공작물을 연속하여 밀어내게 되고, 가이드 튜브(14)로 후방으로 밀려나는 공작물은 하방의 경사판(20)에 받이되어 배출되게 된다.In this way, one of the two opposing spindles (10, 12) is transported to continuously push the workpiece cut behind the guide tube (14) of the opposing spindle (12), pushed back to the guide tube (14) The workpiece is received by the inclined plate 20 to be discharged.

상기 실시예에서는 대향된 주축(10,12)을 갖는 선반의 어느 한 주축(12)에 가공된 공작물을 회수할 수 있는 가이드튜브(14)를 설치하여 설명하였으나 이에 한정되는 것은 아니며 1개의 주축을 갖는 선반에서 주축의 대향측에 이송가능한 가이드튜브를 설치하여 밀어내기 식으로 구성할 수도 있다.In the above embodiment, a guide tube 14 capable of recovering a workpiece may be installed on one of the spindles 12 of the lathe having opposite spindles 10 and 12, but the present invention is not limited thereto. The guide tube which can be transferred to the opposite side of a main shaft in the shelf which it has can also be comprised by the push type.

상술한 바와 같이 본 발명에 의하면 일방의 주축에서 가공된 공작물을 타방의 주축에 설치된 가이드튜브를 통하여 회수되게 함으로서 특히 장축 가공물의 자동화가 경제적으로 유리하고, 구성이 간단하여 설치공간의 제약을 받지 않으며 작업 효율성이 향상되는 장점을 갖는다.As described above, according to the present invention, the workpiece machined on one spindle is recovered through a guide tube installed on the other spindle, and in particular, automation of long-axis workpieces is economically advantageous, and the configuration is simple and is not limited by the installation space. The work efficiency is improved.
