Изобретение относитс к станкостроению, а именно, к поворотным делительным устройствам , используемым в различных отрасл х машиностроени .The invention relates to a machine tool industry, namely to rotary dividing devices used in various fields of engineering.

По основному авт. св. № 425760 известно угловое делительное устройство, содержащее шпиндель, предназначенный дл закреплени обрабатываемой детали, зак .репленный на шпинделе делительный элемент , выполненный в виде многогранника, взаимодействуюш.ий с ним ползун с закрепленной на одном его конце упорной плоскостью , последовательно контактирующей с гран ми многогранника, и привод дл осуществлени возвратно-поступательного перемещени ползуна, причем ползун снабжен второй упорной плоскостью, закрепленной на ползуне с возможностью ее поворота относительно оси многогранника так, что делительный элемент расположен между упорными плоскост ми. Предусмотрено также и параллельное расположение упорных плоскостей 1.According to the main author. St. No. 425760, an angular dividing device is known, comprising a spindle for fixing a workpiece, a dividing element fastened to a spindle, made in the form of a polyhedron, interacting with it a slide with a stop plane fixed at one end and in contact with the edges of the polyhedron and a drive for performing reciprocating movement of the slider, the slider being provided with a second thrust plane fixed on the slider with the possibility of its rotation relative to about the axis of the polyhedron so that the dividing member is disposed between the stop planes. A parallel arrangement of the stop planes 1 is also provided.

Однако данное устройство при четном количестве делений и параллельном расположении упорных плоскостей не обеспечивает надежную работу устройства.However, this device with an even number of divisions and parallel arrangement of the stop planes does not ensure reliable operation of the device.

Цель изобретени - обеспечение надежной работы устройства.The purpose of the invention is to ensure reliable operation of the device.

Поставленна цель достигаетс тем, что многогранник делительного элемента выполнен в виде двух соосно закрепленных на шпинделе и повернутых друг относительно друга на требуемый угол поворота деталей частей, одна из которых установлена с возможностью взаимодействи с первой упорной поверхностью, а друга - со второй упорной поверхностью.The goal is achieved by the fact that the polyhedron of the dividing element is made in the form of two parts that are coaxially mounted on the spindle and turned relative to each other at the required angle of rotation, one of which is installed with the ability to interact with the first thrust surface and the other with the second thrust surface.

На фиг. 1 показано поворотное делительное устройство, общий вид-, на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a rotary dividing device, a general view, in FIG. 2 shows section A-A in FIG. one.

Угловое делительное устройство состоит из шпиндел 1 с приспособлением дл закреплени обрабатываемой детали (не показано ) и с закрепленными на нем двум многогранниками 2 и 3 с четным количеством граней, образующими делительный эле.мент, установленного в направл ющих 4 ползуна 5 с двум упорными планками 6 и 7, The angular dividing device consists of a spindle 1 with a device for fixing the workpiece (not shown) and with two polyhedra 2 and 3 fixed on it with an even number of edges forming the dividing element installed in the guides 4 of the slide block 5 with two stop bars 6 and 7,

Claims

20 is a drive for axial movement of a slider (not shown), a tight 8 connected to the slider. In the central part of the slider, a window 9 is made to accommodate the spindles with a dividing element. The polyhedra 2 and 3 are shifted along the axis of the spindle, and also rotated relative to each other by an angle equal to the desired angle of rotation J5. The working planes of the stop plates are parallel and, with the direction of the rectilinear movement of the slider, form an angle of ° C equal to or close (not more) to the angle of self-locking. If the interacting parts are steel, then this angle is approximately 8-10 °. The working planes of the stop plates are displaced in a direction parallel to the spindle axis in accordance with the displacement of polyhedrons 2 and 3. The slats are fixed on the slider so that the strap 6 when moving the slider has the ability to touch the polyhedron 3, and the strap 7 - with the polyhedron

2. The work of the angular dividing device is as follows. When the slide is running from right to left, the stop bar 6 interacts with one of the edges of the polyhedron 3 and rotates it together with the spindle 1 in the counterclockwise direction to the required angle /. The machining of the part in the first position is performed. Then the slider 5 moves from left to right. The bar 6 goes out of the interface with the polyhedron 3, and the bar 7 comes into contact with one of the edges of the polyhedron 2, turning the spindle in a counterclockwise direction to the required angle. The part is machined in the following position. This is done by splitting and turning the spindle by the required angle the required number of times. In any position at the end of the slide stroke, reliable self-braking is achieved and the drive can be switched off. As a result, when the drive is turned off, the rotation-dividing device reliably maintains the reached position of the spindle with the part. The time it takes to divide and rotate is reduced twice. The proposed device causes an increase in the accuracy of machining parts that require rotation at equal angles during processing, as well as a reduction in the time of division and rotation. Thanks to self-braking, the spindle is securely fixed with the part and the safety of operation is improved. Due to the rotation of the part in one stroke of the slide instead of two, the performance of the part is improved. Claims of the invention Angular dividing device according to ed. St. 425760, characterized in that, in order to ensure reliable operation of the device, the divider element polyhedron is designed as two coaxially mounted on the spindle and rotated relative to each other at the required angle of rotation of the parts, one of which is installed with the possibility of interaction with the first stop plane , and the friend - with the second stop plane.
