Abstract:
본 발명은 스크류식 절삭칩 배출장치 및 방법에 관한 것으로, 상부가 개방되고 내부에 공간부가 형성된 하우징(110)과; 상기 하우징(110)의 내부에 안착되며, 구동수단에 의해 회전되어 절삭칩을 이송시키는 스크류(120)와; 상기 하우징(110)의 전면에 설치되며, 스크류(120)에 의해 이송된 절삭칩이 배출되는 배출관(130);으로 구성되어 절삭칩과 절삭유를 분리 배출시키는 스크류식 절삭칩 배출장치에 있어서, 상기 스크류(120)는 절삭칩을 모을 수 있는 부위가 표면에 형성되어 있는 것을 포함하는 것으로, 본 발명은 CNC 등 각종 공작 기계에서 피 가공물을 가공할 시 발생하는 절삭칩을 무리한 부하가 걸리지 않고, 막힘이 전혀 없게 자동 효율적으로 배출시킴에 따라, 작업자의 작업효율과 고가인 자동화장비의 가동율을 높일 수 있으며, 절삭칩 배출장치에 동심원의 내부로 공간이 넓게 형성된 스크류가 설치되어 절삭칩 이송 시 더 많은 절삭칩과 미세한 절삭칩을 더 잘 이송시킬 수 있는 현저한 효과가 있다.
Abstract:
A tool holder fixing structure is arranged to fix a tool holder (10) for holding a tool (12) attached with a throwaway tip (13) to a tool-holder holding part (31) of a machine tool so that a foreign-matter receiving clearance (19) is provided between the tool holder (10) and the tool-holder holding part (31). The foreign-matter receiving clearance (19) is defined in a range of +30° to -30° from a cutting-edge position of the throwaway tip (13) assumed as an original point and in a range of 150° to 210° from the original point, respectively.
Abstract:
Device for cutting to a precise thickness in the order of 1/100 DEG mm sections of reeds in order to obtain double reeds for wind instruments. Said device is comprised on the one hand of a fixing device (1) for fixing the sections of reeds intended to be planed, and on the other hand of a movable assembly (2) carrying a cutting blade (3) of which the motion is perfectly guided on a rail (4) and by a shaft (5). The adjustment of the thickness of the chip is provided by the rotation of the screw (6). The lateral positioning of the blade with respect to the reed axis is provided by the rotation of the drum (7) graduated in DEG /100 of mm. The thickness of the reed to be made is adjusted by means of a second drum (8) which is also graduated in DEG /100 of mm. The whole unit is firmly secured to a plate (9). The displacement of the movable assembly is easily performed manually by means of the handle (10). In a few planing passes, perfectly calibrated reeds are obtained.
Abstract:
The machine disclosed herein comprises a rotary vat (13) provided with an opening (23) closed by a door (24). Said door comprises locking members and the machine is provided with an automatic locking-unlocking device (26) arranged to automatically lock the door (24) on the vat (13) or to unlock and lift the door to clear the opening (23) of the vat. Said machine further comprises members (27) to load the vat and mechanical drive members to drive the vat (13).
Abstract:
The loader comprises a cross-shaped mandrel holder (18), in which the ends of the arms carry mandrels (12-15) which carry the work piece from a supply station (10) to a work spindle, from there to a turning station (5), to another working spindle and, finally, to a clearing station (11). The driving of the mandrel holders is performed by direct current motors, which are controlled by a programme control incorporating a position closed loop regulation in relation to the machining time of the lathe. The opening and closing motions of all the mandrels provided on the mandrel holders (18) and the turning station (5) are originated from a hydraulic motor of which the control for the opening of the mandrels depends on a fixed time interval element; the starting of the opening is started by the workpiece itself. For the opening, the time element is activated in response to the machine time of the lathe. The loader travels are digitally controlled.
