Изобретение относитс к металлообработке , а именно обработке отверстий .The invention relates to metalworking, namely the processing of holes.

Наиболее близкой к изобретению по технической сущности и достигаемому 5 результату вл етс резцова оправка, содержаща закрепленный в шпинделе станка корпус с механизмом настройки в виде включающей гайку винтовой пары, св занной,с резцедержателем че-tO рез подпружиненный, установленный с возможностью поворота толкатель, . ВХОДЯЩИЙ в паз резцедержател сферической головкой 1.Closest to the invention with the technical essence and the achieved 5 result is a chisel mandrel comprising a housing fixed in the machine spindle with a setting mechanism in the form of a screw pair including a nut, connected with the tool holder four-tO cut pusher. The spherical head entering into the groove of the toolholder 1.

Недостатком ее вл етс невозмож- |5 ность настройки .на стенке в процессе обработки, что ограничивает технологические возможности оправки.Its disadvantage is the impossibility of adjusting the wall during processing, which limits the technological capabilities of the mandrel.

Указанна цель достигаетс тем, что оправка снабжена резьбовой втулкой, контактирующей с резьбой гайки и установленной на корпусе с возможностыг. 25 вращени , при зтом гайка закреплена на неподвижной части станка, а втулка предназначена дл взаимодействи с резцедержателем, который выполнен в виде снабженного продольной лыской 30This goal is achieved by the fact that the mandrel is provided with a threaded sleeve in contact with the thread of the nut and mounted on the housing with the possibility of firing. 25 rotation, with this nut fixed on the fixed part of the machine, and the sleeve is designed to interact with the tool holder, which is made in the form provided with a longitudinal blade 30

На фиг. 1 изображена резцова бправка , общий вид; на фиг. 2 - вид по стрелке А на фиг. 1; на фиг. 3-вид по стрелке В на фиг, 1.FIG. 1 shows the incisal guide, general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow B in FIG. 1.

езцова . опрайка содержит корпус 1, зaj :pёnл ё вjIй в шпинделе 2 станка, И механизм настройки в виде винтовой пары, вкшчающей гайку 3, закрепл емую на неподвижной части 4 станка, и :резьбовую втулку 5, установленную иа корпусе 1 с возможностью вращени зА счет шарикоподшипника 6. eztsov. The quotation contains body 1, forj: plc e in jI in spindle 2 of the machine, and a setting mechanism in the form of a screw pair fitted with a nut 3 fixed on the stationary part 4 of the machine, and: threaded bushing 5 installed in case 1 with the ability to rotate an account ball bearing 6.

Механизм настройки резьбовой втулкой 5 св зан с резцедержателем 7 через подпружиненный пружиной 8 устан6iвлённый с воэможностыо поворота вокруг оси 9 толкатель 10.The adjustment mechanism of the threaded sleeve 5 is connected to the tool holder 7 via a spring loaded spring 8 mounted to the axis 9 of the pusher 10.

Ось 9 закреплена на свободном конце корпуса 1. Опорными точками толкател ЯВЛЯЮТСЯ возвратна пружина 8 и диаметрально расположенный относительто нее регулировочными винт 11, противоположный конец толкател выполнен в виде радиусной головки 12, имеющей форму шара.Axis 9 is fixed at the free end of housing 1. The push points of the pusher ARE a return spring 8 and a diametrically located relative adjusting screw 11, the opposite end of the pusher is made in the form of a radius head 12 having the shape of a ball.

Claims

The head 12 enters the groove 13 of the toolholder 7, which is made in the form of a 37 cylinder 14 fitted with a lip, installed in the corresponding section of the opening 15 of the housing 1. After adjusting the 1O pusher on the housing 9, the adjusting viyt 11 is the spring 8 of the rear cams nut 16. Cutter 17 is strengthened in the tool holder 7, a bolt 18. The arrow 19 serves the ALT of the feed amount over the limb made on the threaded sleeve 5. The handle 20 serves to effect the feed, i.e. to rotate the threaded sleeve 5.. The rotating part of the head is covered by a casing 21. The cutting mandrel works as follows. The housing 1, together with the pusher Yun, the toolholder 7 receives rotation from the spindle 2 of the machine tool. The pusher 10, which is in contact with the support points 8 and 11 with the thrust ball bearing 6, rotates with the housing 1 relative to the threaded sleeve 5. When turning the threaded sleeve 5, the handle 20 turns the sleeve 5 out of the nut 3 and exerts pressure on the bearing points of the parts 8 and II pusher 10 through thrust ball bearing b, so. As one reference point (adjusting screw 11) is rigid, it implements the rotation of the pusher 10 around the axis of rotation 9 and moves the tool 7. The return spring 8 at this time is compressed, P13 and rotation of the sleeve 5 in the opposite direction is screwed into the nut 3, spring 8 returns the plunger 10 and the tool holder 7 to the initial position. The feed amount of the tool holder 7 is carried out over the limb applied to the threaded sleeve 5 for any value within the range of the tool holder. With the help of a mandrel, it is possible to carry out not only a boring, but also cutting of annular channels and cutting threads with adjustment to the size on the machine during processing. Claims of the invention: A mandrel comprising a housing fixed in the machine spindle with a setting mechanism in the form of a screw pair comprising a nut connected to the tool holder via a spring-loaded, rotatably mounted pusher entering the groove of the tool holder in the Hole of the tool holder of the radius head, And so that, with the purpose of adjustment on a wall in the course of a process; The driver is equipped with a threaded sleeve in contact with the nut thread and mounted on the housing so that it can be rotated, while the nut is fixed on the stationary part of the machine, and the sleeve is designed to work with the tool holder, which is made in the form of a longitudinal cylinder and a hole in corpus; cross-section, corresponding to the cross-section of the toolholder.
