(54) СТОЛ МЕТАЛЛОРЕЖУЩЕГО СТАНКА(54) METAL CUTTING TABLE

1one

Изобретение относитс к области станко строени .The invention relates to the field of machine tool building.

Известны столы металлорежущих станков, содержащие приспособление-спутник и планщайбу с установленным в ней с возможностью осевого неремещени цилиндром, с порщием и щтоком, закрепленным в сан х, внутри которого выполнены каналы дл рабочей жидкости.Tables of metal-cutting machine tools are known, which contain a satellite device and a plate washer with a cylinder installed in it with the possibility of axial non-displacement, with a piston and a brush fixed in a hub, inside which channels for the working fluid are made.

Недостатком зтой конструкции стола вл етс ее сложность и возможность перекоса приспособлени -спутника вследствие неравномерности давлени рабочей жидкости в симметричных цилиндрах, что может привести к сгшженшо точности установки приспособлени .The disadvantage of this table design is its complexity and the possibility of skewing of the satellite fixture due to uneven pressure of the working fluid in symmetrical cylinders, which can lead to increased accuracy of the fixture setting.

Целью изобретени вл етс упрощение конструкции и повышение точности установки приспособлени -спутника .The aim of the invention is to simplify the design and improve the accuracy of the installation of the satellite device.

Дл этого в стол введен механизм зажима приспособлени -спутника относительно плашиайбы , выполненный в виде платформы, установленной с возможностью осевого перемещени , в которой размещен жестко св занный с планщайбой посредством стакана дополнительный порщень, расположенный на верхней части штока с возможностью осевого перемещени и снн женный каналами дп рабочей жидкости.To do this, a clamping mechanism of the satellite attachment relative to the plazaiba is introduced into the table, made in the form of a platform mounted for axial movement, in which an additional device rigidly connected to the plate by means of a glass is placed, which can be axially moved and lifted by channels dp working fluid.

Шток выполнен разъемным по длине промежутке между поршнем.The rod is made detachable along the length of the gap between the piston.

На чертеже схематически изображен стол в разрезе.The drawing shows a schematic sectional table.

Стол металлорежущего станка содержит смонтированньш неподвижно в расточке корпуса I саней центральный щток 2.Table cutting machine contains mounted motionless in the bore of the body I sleigh central brush 2.

На поршне 3 штока подвижно в осевом направлении установлен цилиндр 4, жестко соединенный с поворотно-делительным столом 5, в расточке которого смонтирована зубчата полумуфта 6, имеюща зацепление со второй зубчатой полумуфтой 7, установленной в расточке корпуса саней.On the piston 3 of the rod, a cylinder 4 is rigidly mounted in the axial direction, rigidly connected to a rotary-dividing table 5, in the bore of which a gear half coupling 6 is mounted, which engages with a second gear half coupling 7 installed in the bore of the sleigh body.

Внутри штока 2 размещены каналы 8 дл подвода рабочей жидкости в полости над и под поршнем 3.Inside the stem 2, the channels 8 are arranged to supply the working fluid in the cavities above and below the piston 3.

Claims

A cylinder 9 is mounted in cylinder 4, secured against rotation by pin 10 and fixed axially in housing 1 in radial ball under-axle 11. 370 The screw 10 is hooked to shaft 12, which is driven by an elec- torus (not drawn) ). A movable porn 13 is installed on the upper part of the rod 2, which is included in the bore of the plate of the mold 14, on which satellite device 15 is located. Clamping and spinning of the satellite device is carried out by creating pressure of the working fluid, respectively, in the rod cavity 16 and bestoykovoy 17, and In the rod 2, the channels 18 are made for supplying the working fluid in the cavity. The piston 13 is rigidly connected to the rotary-divider table by means of a glass 19, simultaneously serving as a guide for platform 14. The fixture of the -satellite fixture is carried out by two fingers 20 (cylindrical and rhombic) mounted on the rotary dividing table. The rod 2 is made detachable in length between the pistons 3 and 13 with the possibility of lateral displacement of the upper part of the rod relative to the bottom. Moreover, the portions of the CCD are connected to each other by means of a flange 21 and bolts 22 and secured against turning with a pin 23, and in the junction between the parts of the brush in place of the passage of the channels 18 are sealing rings 24. Between the piston 23 of the rod 2 and the bottom of the cylinder 4 A thrust ball bearing 25 is installed. An increase in pressure in the cavity above the rod causes the vertical rotation of the rotary table and the disengagement of the gear half couplings 6 and 7. At the same time, the satellite device 15 moves with the rotary dividing table om, because the latter is rigidly connected by means of the cup 19 with the piston 13, on which the platform 14 is mounted, connected to the satellite device, and the pressure in the cavity 16 is kept constant. After uncoupling the toothed coupling halves, the table 5 is rotated through the electric motor through the screw 9 and 12. The table rotates on the ball thrust bearing 25. When pressure is applied to the cavity under the rod after the table 5 rotates, the coupling half hemispheres 6 and 7 and the clamping the table. When the satellite fixture needs to be changed, the working fluid is supplied to the rodless cavity 17, the clamping platform 14 together with the satellite fixture begins to move upwards and the satellite fixture is released. A special mechanism for changing the satellite attachment (not shown in the drawing) implements its capture and removal from the platform. The clamp of the satellite attachment occurs when pressure is applied to the rod cavity 16. At the same time, the platform 14, together with the satellite device, begins to mix down along the piston 13 and the cup 19, which serves as a guide for the platform. Fixation of the satellite device is carried out by two fingers 20. Claim 1. A metal cutting machine table containing a satellite device and a faceplate with a cylinder installed in it to be axially moved with a cylinder with a piston and a rod fixed in the sleigh, within which the working channels are liquids, characterized in that, in order to simplify the design, improve the accuracy of the installation of the satellite device, the table has a mechanism for clamping it relative to the faceplate, made in the form of a platform installed with the possibility of axial movement, in which an additional piston rigidly connected with it by means of a glass is placed, which is located with the possibility of axial movement on the upper part of the stem and provided with channels for the working fluid.

2. The table according to claim 1, characterized in that, in order to reduce the labor intensity of manufacturing the table parts, the brush is made detachable in length between the pistons.
