Description
Изобретение относитс к станкостроению , в частности к станкам дл сверлени и фрезеровани печатных плат.The invention relates to a machine tool industry, in particular to machines for drilling and milling printed circuit boards.
Целью изобретени вл етс упрощение конструкции путем применени аэростатической п ты дл прижима листовых деталей при сверлении и фрезеровании и использовани выход щего из аэростатического зазора п ты , воздуха дл удалени стружки из зоны резани .The aim of the invention is to simplify the design by using an aerostatic tip to press the sheet parts during drilling and milling and using the air coming out of the aerostatic gap to remove the chips from the cutting zone.
На фиг. 1 Изображено устройство дл прижима, разрезу на фиг. 2 - то же, вид сверху} на фиг. 3 - схем подачи воздуха в п ту и удалени стружкиFIG. 1 shows a pressing device, a section in FIG. 2 - the same, top view} in FIG. 3 - circuits for air supply in ptu and chip removal
Устройство дл прижима.листовых деталей при сверлении и фрезеровании состоит из корпуса 1, жестко св занного посредством промежуточно детали 2 и пневмоцилиндров 3 со станиной . (не показано) станка. В корпусе 1 вьтолнено отверстие 4.The device for pressing the sheet parts for drilling and milling consists of a body 1, rigidly connected by means of an intermediate part 2 and pneumatic cylinders 3 with a frame. (not shown) of the machine. In case 1 there is a hole 4.
Пневмошпиндель 5 инструментом 6 установлен в отверстие 4 корпуса 1.Pneumatic spindle 5 tool 6 is installed in the hole 4 of the housing 1.
Корпус 1 устройства снабжен изолированной камерой 7, образованной прижимной п той 8, поверхностью отверсти 4 и разделительной оболочкой 9, Прижимна п та 8 выполнена в виде диска с р дом отверстий малого диаметра, соединенных микроканавками на рабочем торце-п ты (не показано). П та 8 может быть изготовлена из пористого материала, например металлокерамической композиции . Камера 7 с помощью штуцера 10 и пневмораспределител 11 св зана с пневмосетью сжатого воздуха. Полость 12 устройства соединена сThe housing 1 of the device is provided with an insulated chamber 7, formed by a pressure pin 8, the surface of the opening 4 and a separation shell 9. The fifth 8 may be made of a porous material, for example, a cermet composition. The chamber 7 is connected to a compressed air pneumatic network by means of a fitting 10 and a pneumatic distributor 11. The cavity 12 of the device is connected to

трубопроводом 13 удалени стружки в пьшесборник (не показан). Дл периодической очистки трубопровода 13 имеетс штуцер 14, соединенный 5 с пневмораспределителем 11. Обрабатываема листова деталь 15 устанавливаетс на стол 16 станка.a duct 13 for chip removal to the container (not shown). For periodic cleaning of the pipeline 13, there is a nozzle 14 connected 5 to a pneumatic distributor 11. The sheet part 15 to be machined is mounted on the table 16 of the machine.
Устройство работает следующим образом.The device works as follows.
10 В камеру 7 поступает воздух из пневмосети. Пневмоцилиндры 3 опускают корпус 1 с прижимной п той 8. так, чтобы между п той 8 и поверхностью обрабатываемой детали 15 15 установилс необходимый зазор. Воздух , проход через п ту 8, создает усилие прижима.10 Chamber 7 receives air from a pneumatic circuit. The pneumatic cylinders 3 lower the casing 1 with the pressing pin 8. so that the necessary clearance is established between the fifth 8 and the surface of the workpiece 15-15. The air passing through n 8 creates a pressing force.
Во врем сверлени инструмент 6 посредством своего привода (не по- 20 казан) совершает рабочие движени , а п та 8 неподвижна. При этом часть воздуха из зазора между п той 8 и поверхностью детали 15 поступает во внутреннюю полость 12 устройст- 25 ва и далее, увлека пыль и стружку, отводитс трубопроводом 13 в пьшесборник .During drilling, tool 6, with its actuator (not shown), makes working movements, and the fifth 8 is stationary. At the same time, part of the air from the gap between point 8 and the surface of the part 15 enters the internal cavity 12 of the device 25 and further, entrains dust and chips, is diverted by pipeline 13 to the container.
При фрезеровании по контуру прижимна п та 8 также неподвижна, а JQ стол 16 совершает рабочие движени , и в этом случае обеспечиваетс бес- контактньй прижим обрабатываемой .детали 15 к столу 16. When milling along the contour, the presser n 8 is also stationary, and the JQ table 16 makes the workers move, and in this case the contact piece 15 to the table 16 is made contactless.
В св зи с тем, что часть пыли и стружки оседает на внутренней поверхности трубопровода 13, периодически 2-3 раза в смену осуществл ют продувку трубопровода 13 путем переключени пневмораспределител 11, при этом сжатый воздух, мину п ту 8, поступает в трубопровод 13.Due to the fact that part of the dust and chips accumulates on the inner surface of the pipeline 13, periodically, 2-3 times a shift is carried out to replace the pipeline 13 by switching the valve 11, while the compressed air, minute 8, enters the pipeline 13.
