Изобретение относитс к станкостроению и может быть использовано в станках дл сверлени сквозных отверстий.The invention relates to a machine tool industry and can be used in machine tools for drilling through holes.
Известно устройство дл обработки сквозных отверстий, включающее привод подачи пиноли шпиндел с держателем инструмента и привод его вращени 1. Однако известное устройство имеет низкую стойкость инструмента.A device for processing through holes is known, which includes a drive of supplying quill spines with a tool holder and a drive for rotating it 1. However, the known device has a low tool life.
Цель изобретени - повышение стойкости издели .The purpose of the invention is to increase the durability of the product.
Дл этого устройство снабжено подпружиненной плитой, кинематически св занной с пинолью посредством скалок и с держателем инструмента - посредством подшипника .For this, the device is provided with a spring-loaded plate, kinematically connected with the quill by means of skalok and with the tool holder by means of a bearing.
На чертеже изображен общий вид устройства .The drawing shows a General view of the device.
Обрабатываема деталь 1 установлена на столе 2 станка, а сверло 3 закреплено в патроне 4 и через подшипник 5 соединено с плитой 6, св занной через пружины 7, скалки 8 с пинолью 9 шпиндел стакана 10. Пружины 7 предварительно сжаты гайками 11.The workpiece 1 is mounted on the table 2 of the machine, and the drill 3 is fixed in the chuck 4 and through the bearing 5 is connected to the plate 6 connected through springs 7, the rolling pin 8 to the pinule 9 of the spindle glass 10. The springs 7 are pre-compressed with nuts 11.
Устройство работает следующим образом .The device works as follows.
Сверло 3 под действием усили механизма подачи и привода вращени инструмента производит сверление. Момент перехода на уменьшенную нодачу определ етс величиной наименьшего рассто ни h между вершиной сверла и плоскостью ее выхода из заготовки перед продавлимпнием от усили исходной осевой подали сверла РО, определ емой по формуле / 0,3 1/ , где От - предел текучести обрабатываемого материала.The drill 3 is drilled by the force of the feed mechanism and rotation drive of the tool. The moment of transition to a reduced nodach is determined by the value of the shortest distance h between the top of the drill and the plane of its exit from the workpiece before squeezing the original axial force from the drill bit PO, defined by the formula / 0.3 1 /, where Ot is the yield strength of the material being processed.
Пр1 этом нижние торцы скалок 8 упиратьс в верхнюю плоскость обрабатываемой детали 1 не позднее момента достижени вершиной сверла величины Л, и при последующем их перемещении начинают дополнительно сжимать предварительно ст нутые нружины 7, одновременно выбира люфты и создава осевой противоупругий нат г в системе СПИД.At this time, the lower ends of the rollers 8 abut against the upper plane of the workpiece 1 no later than when the drill tip reaches the value L, and when they are subsequently moved, they start to further compress the collapsed springs 7, simultaneously selecting the backlash and creating an axial anti-elastic tension in the AIDS system.
