Description

Известны конструкции задних бабок к делительным головкам фрезерных станков (см. брошюру ЛДИТП 1957 г. «Автоматизаци  фрезерного станка ТГ-1). В них дл  осуществлени  холостого хода фрезы одновремевно с отводом стола необходимо опускать его вниз. Это приводит к усложнению |Конструкции станка или невозможности осуществлени  автоматического отвода детали от фрезы без изменени  конструкции станка.Designs of tailstocks for dividing heads of milling machines are known (see the 1957 LDTP brochure. Automation of the TG-1 milling machine). In them, in order to idle the cutter at the same time as the table tap, it is necessary to lower it down. This leads to complication of the construction of the machine or the impossibility of automatic removal of the part from the cutter without changing the design of the machine.

Предложенна  задн   бабка свободна от указанного недостатка. Сущность изобретени  заключаетс  в том, что подпружиненна  .пиноль задней бабки .во врем  ра бочего хода донолнительно поджимаетс  с помощью оневматичеокого устройства.The proposed back grandma is free of the indicated disadvantage. The essence of the invention lies in the fact that the spring-loaded tailstock quill of the tailstock is fully tightened during operation by means of a one-off device.

На чертеже схематически изображена описываема  задн   бабка.The drawing schematically depicts the described tailstock.

В «о-рпусе 1 задней ба-бки смонтирована пиноль 2, котора  отжимаетс  вправо пружиной 3. Диск 4 пинолн опираетс  на диафрагму 5, котора  под действием сжатого воздуха, подаваемого в полость а, перемещает пиноль вправо. При этом зажимаетс  обрабатываема  деталь 6.In the o-shaft 1 of the rear tank, a quill 2 is mounted, which is pressed to the right by a spring 3. The quill disk 4 is supported on the diaphragm 5, which, under the action of compressed air fed into the cavity a, moves the quill to the right. In doing so, the workpiece 6 is clamped.

Дл  осуществлени  холостого хода фрезы 7 необходимо из полости а вьшустить сжатый воздух и столу сообщить обратное движение. Под действием фрезы пиноль, поджимаема  только пружиной, перемещаетс  влево, сжима  пружину, что обеспечивает опускание детали вниз, т. е. ее автоматический отвод от фрезы. Деталь после ее обработки снимают со станка с помощью руко тки 8. отвод щей пиноль влево.In order to idle the cutter 7, it is necessary to discharge compressed air from the cavity and push the table back. Under the action of the milling cutter, the quill, which is pressed only by the spring, moves to the left, compressing the spring, which ensures that the part is lowered downwards, i.e., it is automatically retracted from the milling cutter. The part after its processing is removed from the machine with the help of the handle 8., which pushes the quill to the left.

Предмет изоб-ретени Subject of the image

Задн   бабка к дел1ительной головке фрезерного станка, о т л ичающа с  тем, что, с целью автоматического отводка детали от фрезы при ускоренном холостом ходе стола делении, пиноль задней бабки .выполнена шодпружиненной и поджимаемой дополнительно во врем  рабочего хода пневматическим устройством.The tailstock to the splitter head of the milling machine, is so necessary that, in order to automatically disengage the part from the cutter during an accelerated idle run of the division table, the tailstock tailstock is made of spring loaded and additionally pressed during the working stroke by a pneumatic device.
