Description

(54) РАСТОЧНАЯ ГОЛОВКА(54) BORING HEAD

1one

Изобретение относитс  к металлообработке И может .быть использовано в расточных станках.The invention relates to metal working. And can be used in boring machines.

Известна расточна  головка, содержа ща  корпус, в котором расположены кли новой шток и радиальный суппорт l .A known boring head containing the body in which the Kli stem and radial caliper l are located.

Недостатком данной конструкции  вл етс  то, что допустимых люф™ тов не обеспечиваетс  высока  точность обработки.The disadvantage of this design is that the allowable loops do not provide high accuracy of processing.

Целью изобретени   вл етс  повышение точности обработки.The aim of the invention is to improve the accuracy of processing.

Это достигаетс  тем, что предлагавма  головка снабжена подпружиненной клиновой вилкой с роликами на концахс установленной соосно штоку, а суппорт клиновыми выступами, контактирующими с роликами в точках, лежащихв плос. кости, проход щей через ось вращени  головки.This is achieved by offering the head with a spring-loaded wedge fork with rollers at the ends with a coaxially mounted rod, and the caliper with wedge lugs in contact with the rollers at points lying flat. bone passing through the axis of rotation of the head.

. . На фиг, 1 представлена раЬточна  головка в продольном разрезе на фиг. 2- сечение А-А фиг. Ij на фиг. 3 - сечение Б-Б фнг. 2.. . FIG. 1 shows a longitudinal section of the head in FIG. 2 is a section A-A of FIG. Ij in FIG. 3 - section BB fng. 2

Головка содержит сс)став.ной корпус, в котором на роликовых направл ющих расположен суппорт 1 с резцовой оправкой 2. Корпус CocTotrr из жестко скрей-. ленных между собой щеки 3, фланца 4, оправки 5 и защитного кожуха 6.The head contains a casing) housing, in which a support 1 with a cutting mandrel 2 is located on roller guides. The CocTotrr housing is rigidly scrimmed. cheeks 3, flange 4, mandrel 5 and protective casing 6 between them.

В суппорте 1 имеетс  шарнирный , палец 7 сосрезанной лыской 8, котора  контактирует с рабочей поверхностью управл ющего клина 9, -перемещаемого в осевом направлении специальным приводом подачи (не показан). Кроме того, на суппорте 1 имеютс  клиновые выступы 10, расположенные под углом (6О 7О ) к оси головки. Внутри корпуса соосно с управл ющим клином 9 установлены кдинова  вилка 11, на которой закреплены два ролика 12. Под действием пружины 13 ролики 12 упираютс . в поверхность выступов 10. Точки В контактов роликов 12 лежат на пр мой, проход щей через ось вращени  головки во избежание возникновени  усилий, из гибающих корпус головки.In the support 1, there is a hinged, finger 7 with a cut lip 8, which contacts the working surface of the control wedge 9, which is axially displaced with a special feed drive (not shown). In addition, on the support 1 there are wedge protrusions 10 located at an angle (6 ° 7 °) to the head axis. Inside the casing, a two-pin fork 11 is mounted coaxially with the control wedge 9, on which two rollers 12 are fixed. Under the action of the spring 13, the rollers 12 abut. into the surface of the protrusions 10. Points B of the contacts of the rollers 12 lie on a straight line passing through the axis of rotation of the head in order to avoid the occurrence of forces from dying head casing.
