Abstract

PURPOSE: A dual spindle machining tool and a loading and unloading process are provided to selectively shield one or two work-piece spindles by a chip protecting unit at the same time. CONSTITUTION: A machining tool comprises a machine frame, a tool holder(12), a transferring device(18), and a chip protecting unit(20). The machine frame comprises two work-piece spindles(8,8'). The tool holder comprises tools(13). The transferring device transfers work-pieces. The chip protecting unit comprises two baffle plates(25,25'). The tool holder is arranged to be moved in the machine frame. The work-pieces are machined by turns with tools in the inside of the two work-piece spindles so that other work-spindles are loaded or unloaded. Each work-piece is moved from working positions(17,17') to loading positions(19,19'). The baffle plates are moved to standby positions from a domain between the working positions and loading positions for loading and unloading of the two work-piece spindles.

이중 스핀들 공작 기계와 로딩- 및 언로딩 프로세스 {DOUBLE SPINDLE MACHINE TOOL AND LOADING- AND UNLOADING PROCESS}Dual spindle machine tool and loading and unloading process {DOUBLE SPINDLE MACHINE TOOL AND LOADING- AND UNLOADING PROCESS}

본 발명은 특허청구범위 제 1 항의 전제부에 따른 회전식으로 움직이는 공작물(workpiece)들을 가공하기 위한 이중 스핀들 공작 기계와 관련이 있다. 진자 원리(pendular principle)에 따라 작동하는 공작 기계들에서는, 공작물들이 2개의 스핀들 내에서 교대로 가공된다. 한 스핀들에서 공작물이 가공되는 동안, 다른 스핀들은 로딩될 수 있다. 진자 원리는 가공 시간이 짧은 경우에 특히 바람직한데, 즉 유휴 시간(idle time)이 가공 시간보다 크거나 같을 경우에 특히 바람직하다. 유휴 시간을 줄이기 위해, EP 1 711 309 B1호에서는 2개의 공작물 스핀들 및 2개의 터릿(turret)에 숫자상으로 제어되는 4개의 축이 제공되어 있다. 로딩은 워킹 스페이스(working space)의 양 측면에 배치된 2개의 로딩- 및 언로딩 장치를 통해서 이루어진다.
The present invention relates to a dual spindle machine tool for machining rotaryly moving workpieces according to the preamble of claim 1. In machine tools operating according to the pendulum principle, workpieces are machined alternately in two spindles. While the workpiece is being machined on one spindle, the other spindle can be loaded. The pendulum principle is particularly preferred when the machining time is short, i.e. when the idle time is greater than or equal to the machining time. To reduce idle time, EP 1 711 309 B1 is provided with four numerically controlled four axes on two workpiece spindles and two turrets. The loading is done via two loading and unloading devices arranged on both sides of the working space.

본 발명의 과제는 콤팩트한 구조를 나타내고, 워킹 스페이스로부터 칩들이 배출되는 것을 막아주는 칩 보호부(chip protection)를 개선하는 이중 스핀들 선반(lathe)을 단순화하는 것이다.
The object of the present invention is to simplify the dual spindle lathe, which exhibits a compact structure and improves chip protection which prevents chips from being discharged from the working space.

상기 과제는 특허청구범위 제 1 항의 선반에 의해서 해결된다. 바람직한 실시 예들은 종속 항들에 제시된다.
The problem is solved by the lathe of claim 1. Preferred embodiments are presented in the dependent claims.

선반들에서는 진자 원리에 의해 칩들이 2개의 스핀들에 교대로 떨어지기 때문에, 상기 칩들은 마찬가지로 가공 측 변경시에도 로딩 또는 차폐되어야 한다. 특히, 기계들이 콤팩트한 구조를 갖는 경우에는 칩 보호부를 위해 매우 적은 영역만이 사용된다.
In lathes, because of the pendulum principle, chips alternately fall on two spindles, so the chips must likewise be loaded or shielded when changing the machining side. In particular, when the machines have a compact structure, very little area is used for the chip protection.

본 발명의 한 바람직한 양상에 따르면, 2개의 공작물 스핀들에 하나의 텔레스코픽(telescopic)형 칩 보호부가 할당되어 있으며, 상기 칩 보호부는 선택적으로 각각 하나의 공작물 스핀들 또는 필요한 경우 2개의 공작물 스핀들도 동시에 차폐한다.
According to one preferred aspect of the invention, two telescopic chip guards are assigned to the two workpiece spindles, which chip shields optionally also shield one workpiece spindle or two workpiece spindles simultaneously if necessary. .

하기에서는 실시 예를 참고로 본 발명이 더 상세히 기술된다.
In the following the present invention is described in more detail with reference to examples.

도 1은 이중 스핀들 선반의 개략도를 보여준다. 기계 프레임은 수직 측벽들(2, 2') 및 마찬가지로 수직의 앞벽(3)을 갖는 필러(pillar)(1)로서 설계되어 있다. 상기 측벽(2, 2')에서는 가이드 슈(guide shoe)(5) 상에 있는 스핀들 캐리지(spindle carriage)(4, 4')가 가이드(6, 6')를 통해서 수직 방향(Z-축)으로 이동될 수 있다. 구동은 모터(7, 7') 및 도면에 도시되지 않은 볼 스크루(ball screw)를 통해서 이루어진다. 상기 스핀들 캐리지(4, 4')는 각각 공작물 스핀들(8, 8')을 지지한다. 상기 공작물 스핀들의 하부면에는 공작물(10)을 수용하기 위한 인장 수단(tensioning mean)(9, 9')이 배치되어 있다. 앞벽(3)의 상부 부분에서는 툴(13)을 위한 툴 홀더(12)를 갖는 지지체 캐리지(11)가 가이드 레일(14) 상에서 수평 방향(X-축)으로 이동될 수 있다. 상기 지지체 캐리지(11)는 모터(15)에 의해 볼 스크루(ball screw)(16)를 관통하게 된다. 공작물 스핀들(8)은 공작물(10)에 의해 워킹 위치(17)에 있으며, 툴(13)은 상기 공작물(10)에 결합된다. 운반 장치(18)는 가공되지 않은 공작물(10)들을 로드 위치(19, 19')들로 운반하고 가공된 공작물들을 다시 배출한다. 바람직하게 상기 로드 위치(19, 19')는 워킹 위치(17, 17') 바로 아래에 배치되어 있으며, 그 결과 공작물 스핀들(8, 8')은 가이드(6, 6')를 따라서 수직 방향으로 단독으로 이동함으로써 로딩 및 언로딩될 수 있다. 칩 보호부(20)는 깔때기와 유사한 형상을 가지며 레일(22, 23)들 상에서 이동 가능하게 앞벽(3)에 배치되어 있다. 워킹 위치(17, 17')에서 떨어지는 칩은 배플판(25, 25') 통해서 수집 박스(21) 안으로 운반되며, 그 결과 운반 장치(18)는 떨어지는 칩들 및 냉각제들로부터 보호되었다. 특히 바람직하게 칩 보호부(20)는 수평 방향으로 텔레스코픽형으로 신축될 수 있다. 이 목적을 위해 개별 리프팅 실린더(24)들을 갖는 배플판(25, 25')들이 필요한 경우에 개별적으로 이동될 수 있다. 도 1에 따른 도시에서, 2개의 배플 판(25, 25')은 워킹 위치(17, 17')들 아래에 배치되어 있다. 워킹 위치(17)에서 공작물이 가공되는 동안, 예컨대 척(9')은 워킹 위치(17')에서 세척 또는 배기에 의해 정화될 수 있다. 상부면에서 칩 보호부(20)는 이 칩 보호부가 툴 홀더(12)를 아래로부터 둘러쌀 정도로 올려진다. 1 shows a schematic of a dual spindle lathe. The machine frame is designed as a pillar 1 with vertical side walls 2, 2 ′ and likewise a vertical front wall 3. On the side walls 2, 2 ′ spindle carriages 4, 4 ′ on the guide shoe 5 are vertically guided through the guides 6, 6 ′ (Z-axis). Can be moved to. The drive is made via motors 7, 7 ′ and a ball screw not shown in the figure. The spindle carriages 4, 4 ′ support the workpiece spindles 8, 8 ′, respectively. Tensioning means 9, 9 ′ are arranged on the lower surface of the workpiece spindle for receiving the workpiece 10. In the upper part of the front wall 3 a support carriage 11 with a tool holder 12 for the tool 13 can be moved in the horizontal direction (X-axis) on the guide rail 14. The support carriage 11 passes through the ball screw 16 by the motor 15. The workpiece spindle 8 is in working position 17 by the workpiece 10, and the tool 13 is coupled to the workpiece 10. The conveying device 18 carries the raw workpieces 10 to the load positions 19, 19 ′ and ejects the processed workpieces again. Preferably the rod positions 19, 19 ′ are arranged just below the working positions 17, 17 ′ so that the workpiece spindles 8, 8 ′ are perpendicular to the guides 6, 6 ′. It can be loaded and unloaded by moving alone. The chip protection 20 has a shape similar to the funnel and is disposed on the front wall 3 so as to be movable on the rails 22 and 23. Chips falling at the working positions 17, 17 ′ are transported into the collection box 21 through the baffle plates 25, 25 ′, as a result of which the conveying device 18 is protected from falling chips and coolants. Particularly preferably, the chip protection unit 20 may be telescopically stretched in the horizontal direction. For this purpose baffle plates 25, 25 ′ with separate lifting cylinders 24 can be moved individually if necessary. In the illustration according to FIG. 1, two baffle plates 25, 25 ′ are arranged below the working positions 17, 17 ′. While the workpiece is being processed at the working position 17, for example, the chuck 9 ′ can be cleaned by washing or evacuation at the working position 17 ′. On the top surface, the chip protector 20 is raised to such an extent that the chip protector surrounds the tool holder 12 from below.

도 2는 공작물 스핀들(8') 로딩시의 도 1에 따른 선반을 보여준다. 배플 판(25')은 리프팅 실린더(24)에 의해 스탠바이 위치(26')로 이동되었으며, 공작물 스핀들(8')은 가공되지 않은 공작물(10)을 수용하기 위해 가이드(6')를 따라서 로드 위치(19')로 이동되었다. 도 3은 가공 측을 변경한 후의 선반을 보여준다. 공작물 스핀들(8')은 다시 워킹 위치(19')에 위치하고, 상기 위치에서 새로운 공작물(10)을 가공하기 위해, 툴 홀더(12)는 가이드 레일(14)들을 따라서 이루어지는 이동에 의해 기계의 좌측면으로부터 우측면으로 이동되었다. 공작물 스핀들(8)을 언로딩하기 위해서, 스탠바이 위치(26)의 배플판(25)이 파킹(parking)되었다.
2 shows the lathe according to FIG. 1 at the time of loading the workpiece spindle 8 ′. The baffle plate 25 'is moved to the standby position 26' by the lifting cylinder 24, and the workpiece spindle 8 'is loaded along the guide 6' to receive the raw workpiece 10. Moved to position 19 '. 3 shows the lathe after changing the machining side. The workpiece spindle 8 'is again located in the working position 19', in order to machine the new workpiece 10 in that position, the tool holder 12 is moved to the left side of the machine by a movement along the guide rails 14. Moved from face to right. In order to unload the workpiece spindle 8, the baffle plate 25 in the standby position 26 has been parked.

도 4는 선반을 측면도로 보여준다. 본 도면에는, 측벽(2)에서 가이드(6) 상으로 이동될 수 있는 스핀들 캐리지(4)가 나타난다. 공작물 스핀들(8) 내에 있는 공작물(10)은, 그 뒤에 걸려있는 공작물 지지체(12)의 툴들에 의해 가공된다. 칩 보호부(20)는 가이드 슈들에 의해 레일(22, 23)들에서 가이드 되었다.
4 shows the shelf in side view. In this figure, a spindle carriage 4 is shown which can be moved from the side wall 2 onto the guide 6. The workpiece 10 in the workpiece spindle 8 is machined by the tools of the workpiece support 12 hanging behind it. The chip protection 20 was guided on the rails 22, 23 by guide shoes.
