Однако данное устройство конструктивно сложно и громоздко, что ограничивает область его применения.However, this device is structurally complex and bulky, which limits the scope of its application.

Целью изобретения является упроще-25 ние конструкции и повышение надежности работы устройства.The aim of the invention is to simplify the design and increase the reliability of the device.

Указанная цель достигается тем, что устройство снабжено двумя подпру.жиненными дисками, установленными на 30 корпусе и предназначенными для торможения шпинделя.This goal is achieved by the fact that the device is equipped with two spring-loaded disks mounted on the 30 casing and designed to brake the spindle.

На фиг. 1 показано устройство, общий вид; на фиг. 2 — разрез А-А на фиг. 1.In FIG. 1 shows a device, a General view; in FIG. 2 is a section AA in FIG. 1.

В корпусе 1 устройства укреплена ось 2, на которой подвижно установлена втулка-шестерня 3, приводимая во вращение рейкой 4 от гидроцилиндра 5. На оси 6, укрепленной во втулке 3, подвижно установлен ролик 7, помещенный в паз кулачка 8, свободно установленного на втулке-шестерне 3. Во втулке 9, жестко соединенной с кулачком 8, помещен шпиндель 10, выполненный в виде стакана и имеющий ребро 11 для взаимодействия с торцовым пазом ориентируемой детали 12 и подпружиненный относительно кулачка 8 пружиной 13. Палец 14, укрепленный во втулке 9, помещен в продольный паз шпинделя 10 и препятствует его вращению относительно втулки 9 и кулачка 8. Подпружиненные друг к другу пружиной 15 диски 16 взаимодействуют с кулачком 8, а укрепленная в корпусе 1 ось 17 препятствует вращению дисков Гб.An axle 2 is mounted in the housing 1 of the device, on which the sleeve-gear 3 is movably mounted, driven by a rack 4 from the hydraulic cylinder 5. On the axis 6, mounted in the sleeve 3, a roller 7 is mounted movably in the groove of the cam 8 freely mounted on the sleeve gear 3. In the sleeve 9, rigidly connected to the cam 8, a spindle 10 is placed, made in the form of a cup and having a rib 11 for interacting with the end groove of the orientable part 12 and spring-loaded relative to the cam 8 by a spring 13. The finger 14, mounted in the sleeve 9, placed in longitudinal the groove of the spindle 10 and prevents its rotation relative to the sleeve 9 and the cam 8. The disks 16, spring-loaded to each other by a spring 15, interact with the cam 8, and the axis 17 fixed in the housing 1 prevents the rotation of the disks GB.

Устройство работает следующим образом.The device operates as follows.

При включении гидроцилиндр'а 5 рейка 4 вращает втулку-шестерню 3 по часовой стрелке. Так как кулачок взаимодействует с невращающимися, но скальзящими вдоль оси 17 дисками 16, то под действием ролика 7 кулачок 8 вместе’со втулкой 9 и шпинделем 10 ' ^э перемещается влево. Ребро 11 шпинделя 10 упирается в торец детали 12, в результате чего шпиндель 10 утапливается во втулку 9, сжимая пружину 13.When the hydraulic cylinder 5 is turned on, the rack 4 rotates the gear sleeve 3 clockwise. Since the cam interacts with disks 16 that do not rotate but slide along the axis 17, under the action of the roller 7, the cam 8, together with the sleeve 9 and the spindle 10 ' ^e, moves to the left. The rib 11 of the spindle 10 abuts against the end of the part 12, as a result of which the spindle 10 is recessed into the sleeve 9, compressing the spring 13.

После того, как ролик 7 дойдет до конца паза в кулачке 8, последний вместе со втулкой 9 и шпинделем 10 начинает вращаться заодно со втулкойшестерней 3, преодолевая трение меж- 15 ду дисками 16 и кулачком 8. При этом ребро 11 шпинделя 10 сначала скользит по торцу неподвижной детали 12, затем западает в паз этой детали и вращает ее. Так как поворот шпинделя 10 сос- 20 тавляет не менее 180° (это обеспечивается соответствующим ходом гидроцилиндра 5) и останавливается всегда в определенном положении, то и поворот детали 12 производится до определенного ориентированного положения.After the roller 7 reaches the end of the groove in the cam 8, the latter, together with the sleeve 9 and the spindle 10, starts to rotate along with the gear sleeve 3, overcoming friction between the disks 16 and the cam 8. In this case, the edge 11 of the spindle 10 first slides along the end of the stationary part 12, then sinks into the groove of this part and rotates it. Since the rotation of the spindle 10 is at least 180 ° (this is ensured by the corresponding stroke of the hydraulic cylinder 5) and always stops in a certain position, the part 12 is rotated to a certain oriented position.

При обратном вращении втулки-шестерни 3 кулачок 8, втулка 9 и шпин дель 10 сначала отходят от детали 12, смещаясь вправо, а затем вращаются вместе со втулкой-шестерней 3, возвращаясь в исходное положение.With the reverse rotation of the gear sleeve 3, the cam 8, the sleeve 9 and the spinel del 10 first move away from the part 12, moving to the right, and then rotate together with the gear sleeve 3, returning to its original position.

Claims

The invention relates to mechanical engineering and can be used in the automation of machining processes and the assembly of parts. A spindle feeding device is known by means of a gear-cam mechanism and an actuator which rotates and reciprocates at a different angular speed. 1. The disadvantage of this device is the structural complexity and possible violation of the oriented position of the part during the spindle retraction. It is also known a device containing a spindle mounted in the housing with the possibility of reciprocating movement and rotation from the cam-gear mechanism and the drive 2. However, this device is structurally complicated and cumbersome, which limits its scope. The aim of the invention is to simplify the design and increase reliable operation of the device. This goal is achieved by the fact that the device is equipped with two sub-spring disks mounted on the housing and designed to brake the spindle. FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. 1. In the device case 1, an axis 2 is fixed, on which a gear-hub 3 is movably mounted, driven in rotation by a rail 4 from a hydraulic cylinder 5. On a 6-axis, fixed in hub 3, a roller 7 is movably mounted, placed in the groove of the cam 8, freely mounted on the gear hub 3. In the hub 9, rigidly connected to the cam 8, a spindle 10 is placed, made as a cup and having a rib 11 for engagement with the end groove of the oriented part 12 and spring-loaded relative to the cam 8 by the spring 13. Finger 14 fixed in the hub 9, placed in pro The spline 10 has a groove and prevents its rotation relative to the sleeve 9 and the cam 8. The disks 16 spring-loaded to each other by the spring 15 interact with the cam 8, and the axis 17 fixed in the housing 1 prevents the disks 16 from rotating. The device works as follows. When the hydraulic cylinder is turned on, the 5 rail 4 rotates the gear-hub 3 clockwise. Since the cam interacts with the discs 16 which do not rotate but move along the axis 17, then under the action of the roller 7 the cam 8 together with the sleeve 9 and the spindle 10 moves to the left. The rib 11 of the spindle 10 rests on the end face of the part 12, causing the spindle 10 to sink into the sleeve 9, compressing the spring 13. After the roller 7 reaches the end of the groove in the cam 8, the latter together with the sleeve 9 and the spindle 10 begins to rotate at the same time bushing gears 3, overcoming the friction between the disks 16 and the cam 8. In this case, the edge 11 of the spindle 10 first slides on the end face of the stationary part 12, then sinks into the groove of this part and rotates it. Since the rotation of the spindle 10 is at least 180 (this is ensured by the corresponding stroke of the hydraulic cylinder 5) and always stops at a certain position, the rotation of the part 12 is carried out to a certain oriented position. In the reverse rotation of gear sleeve 3, the cam 8, sleeve 9 and spindle 10 first move away from part 12, shifting to the right, and then rotate with gear sleeve 3, returning to their original position. An apparatus for orientation of parts comprising a spindle mounted in a housing with the possibility of reciprocating movement and rotation around a longitudinal axis by means of a cam-gear mechanism, characterized in that, in order to simplify the design and increase reliability of operation, it is equipped with two spring-loaded disks, mounted on the housing and designed to brake the spindle.
