Abstract

Изобретение касаетс  токарной обработки. Целью изобретени   вл етс  упрощение конструкции за счет выполнени  узла нат жени  детали в виде двух полумуфт 4 и 5, соединенных между собой подвижно посредством резьбы, причем полумуфта 4 установлена на шпинделе 2 станка, а полумуфта 5 на патроне 1. При врезании резца 12 в тело детали 3 момент кручени  детали, возникающий между зоной резани  и шпинделем 2 станка за счет завинчивани  одной полумуфты на другую, приводит к возникновению раст гивающей силы. 1 з.п. ф-лы, 2 ил.The invention relates to turning. The aim of the invention is to simplify the design by making the part tension unit in the form of two coupling halves 4 and 5 movably interconnected by means of a thread, with the coupling half 4 mounted on the spindle 2 of the machine and the coupling half 5 on the chuck 1. The part 3, the torque of the part arising between the cutting zone and the spindle 2 of the machine tool, by screwing one coupling half to the other, results in a tensile force. 1 hp f-ly, 2 ill.

Изобретение относитс  к токарной обработке .The invention relates to turning.

Цель изобретени  - упрощение конструкции устройства.The purpose of the invention is to simplify the design of the device.

Указанна  цель достигаетс  за счет обеспечени  регулировки нат жени  детали в зависимости от момента кручени  детали из-за воздействи  на деталь сил резани .This goal is achieved by ensuring that the tension of the part is adjusted depending on the moment of the torsion of the part due to the impact of the cutting forces on the part.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one.

Устройство дл  раст жени  нежестких деталей при токарной обработке содержит патрон 1, установленный на щпинделе 2 станка ,и узел нат жени  детали 3. Патрон 1 установлен на шпинделе 2 посредством узла нат жени , выполненного в виде полумуфт 4 и 5, подвижно соединных между собой с помощью резьбы б (правой).A device for stretching non-rigid parts during turning comprises a cartridge 1 mounted on a chuck 2 of the machine, and a tension unit of the part 3. The cartridge 1 is mounted on a spindle 2 by means of a tension node made in the form of coupling halves 4 and 5 movably connected with using the thread b (right).

В описываемом варианте исполнени  предлагаемого устройства между полумуфтами 4 и 5 установлен упругий элемент 7, закрепленный в полумуфте 4, котора  имеет опорное кольцо 8, соединенное с ней при помощи винтов 9 и служащее дл  ограничени  хода полумуфты 5 с патроном 1.In the described embodiment of the proposed device, between the coupling halves 4 and 5, there is an elastic element 7 fixed in the coupling half 4, which has a support ring 8 connected to it with screws 9 and serves to limit the movement of the coupling half 5 with the cartridge 1.

Устройство также имеет патрон 10, установленный на пиноли 11 задней бабки.The device also has a cartridge 10 mounted on quill 11 of the tailstock.

Устройство дл  раст жени  нежесткихDevice for stretching non-rigid

деталей при токарной обработке работает следующим образом.parts during turning works as follows.

Деталь 3 закрепл ют в патроны 1 и 10. Дают предварительное раст жение детали за счет осевого перемещени  пиноли 11 задней бабки. При этом полумуфта 5 должна быть перемещена вправо до упорного кольца 8. Подвод т резец 12 к детали 3 и начинают обработку . При вращении щпиндел  полумуфта 5 с закрепленным на ней патроном 1 стремитс  переместитьс  влево, навинчиваетс  на полумуфту 4 по резьбе б, раст гива  деталь 3. Дополнительное раст жение детали 3 придает ей большую жесткость.Part 3 is fixed in the chucks 1 and 10. The part is pre-stretched by axial movement of the quill 11 of the tailstock. In this case, the coupling half 5 must be moved to the right up to the stop ring 8. The cutter 12 is supplied to the part 3 and the machining is started. When rotating, the spindle of the half-coupling 5 with the chuck 1 fixed on it shifts to the left, screwed onto the coupling half 4 along the thread b, stretching the component 3. Additional stretching of the component 3 gives it greater rigidity.
