Description
II
Изобретение относитс к шлифованию пера или прикомлевых участков лопаток газотурбинных двигателей и может быть использовано.в ленточно-шлифовальных станках типа ЗЛШ-41, ЗЛШ-21, 3813Д и др.The invention relates to the grinding of feathers or gibgles of gas turbine engine blades and can be used in belt grinders such as ZLSh-41, ZLSh-21, 3813D and others.
Известен ленточно-шлифовальный станок дл обработки лопаток, содержащий механизмы ускоренной и рабочей подачи, упор ограничени подачи и пиноль , с которой жестко соединен палец ограничени подачи и контактный копир с огибающей его шлифовальной лентой D .A blade grinding machine is known that includes blades for accelerated and working feed, a feed restriction stop and a quill with which the feed restriction finger is rigidly connected, and a contact copier with a grinding tape D around it.
Недостатком этого станка вл етс то, что переход с быстрого подвода ленты с копиром к детали на рабочую подачу осуществл етс не в момент их соприкосновени , а несколько раньше- с учетом рассе ни допуска при пуска на обработку, что снижает ее производительность, так как скорость рабочей подачи значительно меньше скорости быстрого подвода и при преждевременном уменьшении скорости подачи часть пути подвода производитс с медленной (рабочей) скоростью подачи.The disadvantage of this machine is that the transition from the fast supply of the tape with a copier to the part to the working feed is carried out not at the time of their contact, but somewhat earlier, taking into account the dispersion of the tolerance during start-up, which reduces its productivity, since the speed the working feed is significantly less than the fast approaching speed and, with a premature reduction in the feed rate, part of the supply path is performed at a slow (working) feed rate.
Цель изобретени - пов1-Ш1ение производительности обработки за счет перехода быстрой подачи на рабочую в момент касани обрабатываемой детали инструментом.The purpose of the invention is to increase the machining productivity by switching the quick feed to the working one when the tool touches the workpiece.
Дл достижени этой цели упор ограничени подачи установлен с возможностью посто нного контактировани с палв цем ограничени подачи и перемещени от механизмов ускоренной или рабочей подачи в введенных в станок направл ющих , жестко соединенных с корпусом пиноли.To achieve this goal, the feed restriction stop is installed with the possibility of constant contact with the stake of restricting the feed and movement from the accelerated or working feed mechanisms into the guides, rigidly connected to the housing, introduced into the machine.
На фиг. 1 схематически изображена кинематическа схема станка в плоскости вращени ленты; на фиг. 2 узел соединени муфты обгона с приводами быстрого подвода и рабочей подачи .FIG. Figure 1 shows schematically the kinematic diagram of the machine in the plane of rotation of the belt; in fig. 2 connection unit for overtaking clutch with fast feed and working feed drives.
