Изобретение относитс к металлообработке .The invention relates to metal working.

Известно устройство дл ориентации зубчатых колес, в котором механизм ориентации выполнен в виде корпуса с расположенным внутри ориентирующим элементом с зубчатым венцом на конце 1 .A device for orientation of gear wheels is known, in which the orientation mechanism is made in the form of a housing with an orienting element located inside with a gear ring at the end 1.

Однако работа такого устройства не надежна , так как при непопадании в зацепление возможен проворот не зажатого зубчатого колеса вместе с ориентирующим элементом за счет сил трени .However, the operation of such a device is not reliable, since if it does not engage in engagement, it is possible to twist the non-clamped gear together with the orienting element due to the forces of friction.

При этом точность фиксированного положени не высока, так как доворот происходит не до жесткого упора, что снижает точность обрабатываемого зубчатого колеса .At the same time, the accuracy of the fixed position is not high, since the rotation does not occur to a hard stop, which reduces the accuracy of the gear to be machined.

Цель изобретени - обеспечение надежности ввода в зацепление ориентирующего элемента с зубчатым колесом и повышение точности фиксированного положени последнего относительно инструмента при зафиксированной в определенном положении кинематической цепи станка.The purpose of the invention is to ensure the reliability of the engagement of the orienting element with the gear wheel and to increase the accuracy of the fixed position of the latter relative to the tool when the machine kinematic chain is fixed in a certain position.

Дл достижени этой цели механизм ориентации снабжен направл ющим пальцем, упорной втулкой и подпружиненным тормозным кольцом, причем упорна жестко закрег лена на ориентирующем элементе , по наружной поверхности которого выполнен винтовой паз, контактирующий с направл ющим пальцем, закрепленным в корпусе, несуще.м подпружиненное тормозное кольцо.To achieve this goal, the orientation mechanism is equipped with a guide pin, an anvil sleeve and a spring-loaded brake ring, with the anvil rigidly fixed on the orienting element, on the outer surface of which a screw groove is in contact with the guide pin fixed in the housing, bearing spring-loaded brake ring.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 ---- взаимное расположение ор11ентирующего элемента и зубчатого колеса.FIG. 1 shows the proposed device, a general view; in fig. 2 ---- the relative position of the orienting element and the gear.

10 Устройство содержит корпус 1. внутри которого установлен ориентирующий элемент 2, передний конец которого выполнен в виде зубчатого венца 3, с заостренными по торцу зубь ми 4. На ориенгирующем элементе 2 выполнен винтовой паз 5 с углом 10 The device comprises a housing 1. inside of which an orienting element 2 is installed, the front end of which is made in the form of a gear rim 3, with teeth pointed at the end 4. On the orientation element 2 there is a screw groove 5 with an angle

В корпусе 1 установлен направл ющий палец 6, взаимодействующий с винтовым пазом 5. На корпусе смонтировано подпружиненное пружинами 7 тормозное кольцо 8.A guide pin 6 is mounted in the housing 1 and interacting with a screw groove 5. A brake ring 8 spring-loaded with springs 7 is mounted on the housing.

Claims

20 Ring 8 is set relative to the front end of the body at a distance slightly greater than the value "H, defined by the formula H; + h. providing a hard stop in the oriented position of the gear. The installation of the ring 8 on the size "N" is provided by the design of the device details. At the rear end of the orienting element, a flange 11 is pressed rigidly against the end 9 by a spring 10. On the orienting element 2, a stop sleeve 12 is rigidly fixed. The reciprocating movement of the device is provided by the actuator 13. The device operates as follows. The device is moved by the actuator 13 along the axis of the gear, which is freely centered on the mandrel. As it moves, the ring 8 rests on the end of the gear 14 and keeps the latter from turning due to the frictional forces created by the springs 7. As the housing 1 moves further, the orienting element 2 approaches the end of the gear 14. When the orienting element 2 engages with the toothed one the wheel 14 moves until it engages with the stop sleeve 12. Then the body 1 moves by interacting the guide pin 6 with the screw groove 5 turns the orienting element 2, which turns the cage 14. Turning continues until the front end of housing 1 rests on the end of brake ring 8 by selecting a clearance “H, i.e., up to a hard stop defining the oriented position of the gear 14. The cogwheel 14 is then clamped. and retraction of the orienting device to the initial position by means of the actuator 13. When the orienting element 2 does not engage with the gear wheel 14, its rotation begins immediately after the butt stops with the ring gear 3 at the end of the gear wheel 14, and continues until the tooth 4 into the cavity of the gear wheel 14, as a result of which a gap is formed between the flange 11 and the end face 9 of the housing 1, which, after engaging the orienting element 2 and the gear wheel 14, is selected by the action of the spring 10. After the orienting element 2 engages with the gear wheel 14, the movement takes place before interacting with the stop sleeve 12. Then the housing 1, continuing to move relative to the orienting element through the interaction of the guide pin 6 and the screw groove 5, turns the orienting el An element whose gear ring turns the gear wheel 14. The rotation continues until the front end of the body 1 rests on the end face of the brake ring 8, the gap "H, i.e., to the hard stop defining the oriented position of the gear wheel 14, is selected. Then, the gear wheel 14 is clamped and the orienting device is retracted to the initial position by means of the drive 13. The description provides an example of the orientation of the internal gear wheel relative to the cutting tool on the tooth-rounding machine. This device can also be used to orient the gears of the engagement on the anti-roll bar. An apparatus for orienting gear wheels, wherein the orientation mechanism is made in the form of a housing with an internally oriented element with a ring gear at the end, characterized in that, in order to improve the accuracy and reliability of fixation, the orientation mechanism is provided with a guide pin, an anvil sleeve and a spring-loaded brake ring, wherein the stop sleeve is rigidly fixed on the orienting element, on the outer surface of which a screw groove is made, in contact with the guide pin, secured Replaced in the housing, carrying a spring-loaded brake ring.
