Description

II

Изобретение относитс к машиностроению и может быть использовано дл глубокой расточки деталей тнпа трубы..The invention relates to mechanical engineering and can be used for deep boring of parts of a pipe TNP.

Известны глубокорасточные станки, содержащие расположенные на станине шпиндельную бабку с эахсимным патроном и стеблевую бабку, несущую борштангу , размещенную в опорах с подшипниками , установленными соосно со шпинделем llXKnown to the deep cutting machines, containing spindle headstock located on the frame with an axial chuck and stem stem bearing boring bar placed in bearings with bearings mounted coaxially with spindle llX

Недостатком этих станков вл етс то, что борштанга выполнена составной , разъем в борштанге уменьшает жесткость системы СПИД станка, а кроме того, установка и сн тие детали сложны.The disadvantage of these machines is that the boring bar is made integral, the connector in the boring bar reduces the rigidity of the AIDS system of the machine, and in addition, installation and removal of the part is complicated.

Цель изобретени - увеличение жесткости системы СПИД станка.The purpose of the invention is to increase the rigidity of the AIDS machine tool system.

Дл этого предлагаемый станок снабжен размещенным на станине рольганге, несущим приводные ролики дл установочного перемещени обрабатываемой детали в зону обработки, и роликами дл поддержани последней При установочном перемещении, расположенными в шпиндельной бабке, а подшипник одной из опор борштанги со стороны ввода обрабатываемой детали выполнен составным , причем его части установлены с For this, the proposed machine is equipped with a roller table placed on the frame carrying the drive rollers for the installation movement of the workpiece to the treatment area, and rollers for supporting the latter. When the installation movement is located in the headstock, the bearing of one of the boring bar supports on the input side of the workpiece is composite, and its parts are installed with

ВОЗМОЖНОСТЬЮ перемещени в направлении , перпендикул рном оси борштанги.With the POSSIBILITY of movement in the direction perpendicular to the axis of the boring bar.

На фиг. 1 изображен предлагаемый, станок, общий вид; на фиг. 2 - вид А фиг. 1.«FIG. 1 shows the proposed, machine, general view; in fig. 2 - view A of FIG. one."

На станине 1 расположены бабка 2 и люнет 3, несудае шпиндели 4 и 5, приводимые от двигател 6. В шпиндельной бабке 2 и люнете 3 размещены самоцентрирующие патроны 7 и В, приводимые от двигателей 9. В патронах, к зепитс обрабатываема деталь 10. Стеблева бабка 11, несуща борштангу 12, приводитс . в движение двигателем подач 13. Борштанга 12, несуща расточную го.Г1ОвкуOn the bed 1, the headstock 2 and the rest 3 are located, the spindles 4 and 5, driven by the engine 6, are not moving. Self-centering cartridges 7 and B, which are driven by engines 9, are placed in the spindle headstock 2 and the backrest 3. 10 in the cartridges, the part 10 is machined. grandma 11 carrying boring bar 12 is driven. In the motion of the engine feeds 13. Boring 12, carrying a boring go.G1Ovku

15,а второй конец ее поддерживаетс составным подшипником опоры 16, имеющим привод 17, обеспечивающий перемещение половинок подшипника 18. Приводные ролики рольганга 19 с двигателем 20 установлены на станине.15, and its second end is supported by a composite bearing of the support 16, having a drive 17, which provides movement of the bearing halves 18. The drive rollers of the roller table 19 with the engine 20 are mounted on the frame.

Ролики 21 располагаютс по внутреннему диаметру шпиндел бабки равномерно , обеспечива поддержку обрабатываемой детали при ее установке и сн тии со станка. На стеблевой бабке размещен двигатель 22 радиальной подачи резцов.The rollers 21 are arranged evenly over the inner diameter of the headstock spindle, providing support for the workpiece during its installation and removal from the machine. On the stem of the grandmother is placed the engine 22 radial supply of incisors.

Claims

The machine works as follows. As the rollers 19 rotate, the part 10 moves past the divorced halves of the bearings 18, the supports 16, inside the spindles 4 and 5 along the roller 21 (loading of the part). By rotating the rotors of the diggers 9, the centering and pressing of the part 10 is performed with the cartridges 7 and 8, and the drive 17, the halves of the spike 18 and the centering of the end of the drill rod 12. Next, during operation of the engine 6, the spindles 4 and 5 are rotated with the clamped part 10 and when the engine 13 is in operation, the longitudinal feed of the stem headstock 11 with boring bar 12 provides the bore of part 10. By rotating the rotor of the engine 22, the cutters radially feed the bores of head 14. During movement of the stem headstock, the boring bar 12 is guided After the bore of the part, the stem headstock 11 returns to its original position, the spindles stop rotating, the cartridges open and the bearing halves are unfastened. 16. And then, rotating the rollers 19 in the reverse direction, part 10 is removed from spindles 4 and 5 (unloading parts). Formula of the invention A deep-depth machine containing a spindle head located on a bed with a clamping chuck and a stem head bearing borstant placed in supports with bearings mounted coaxially with the spindle, which is similar to the fact that, in order to increase the rigidity of the AIDS machine, it equipped with a roller table placed on the frame carrying the drive rollers for the installation movement of the workpiece to the treatment area, and rollers for supporting the latter during the installation movement, located in the pintockstock, and the bearing of one of the boring bar supports on the input side of the workpiece is made composite; moreover, its parts are mounted with the possibility of movement in the direction perpendicular to the axis of the boring bar.
