(54) УСТРОЙСТВО ДЛЯ ЗАЖИМА ДЕТАЛЕЙ(54) DEVICE FOR CLAMPING DETAILS

1one

Изобретение относитс к станкостроению в частности к установочно-зажимным приспособлени м агрегатных станков и автоматических линий.The invention relates to a machine tool industry in particular to mounting and clamping devices of aggregate machines and automatic lines.

Известно устройство дл зажима деталей , содержащее устанс(вочный элемент и подвижную приводную т гу с осью, на которой шарнирно закреплен двуплечий прихват (1 .A device for clamping parts is known, which contains a rig (a lateral element and a movable drive bar with an axis on which a two-armed strap is hinged (1.

Недостатком этого устройства вл етс невозможность осуществлени ориентации и зажима детали по двум взаимно перпендикул рным направлени м от одного привода .A disadvantage of this device is the impossibility of orientation and clamping of the part in two mutually perpendicular directions from one drive.

Цель изобретени - расширение технологических возможностей путем бсуществлени ориентации и зажима детали по двум взаимно перпендикул рным направлени м от одного привода.The purpose of the invention is the expansion of technological capabilities through the implementation of orientation and clamping of parts in two mutually perpendicular directions from a single drive.

Поставленна цель достигаетс тем, что установочный элемент выполнен составным из неподвижной части и подпружиненной со сквозным отверстием, предназначенным дл размещени в нем одного плеча прихвата, а устройство снабжено упором, закрепленным на подпружиненной части установочного элемента и предназначенным дл взаимодействи с осью т ги.The goal is achieved by the fact that the mounting element is made up of a fixed part and is spring-loaded with a through hole, designed to accommodate one shoulder strap, and the device is equipped with an abutment fixed to the spring-loaded part of the mounting element and intended to interact with the axis of the rod.

На фиг. 1 изображено устройство, продольный разрез; на фиг. 2 - разрез А-А 5 на фиг. 1; на фиг. 3 - вид по стрелке Б на фиг. 2.FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A 5 in FIG. one; in fig. 3 is a view along arrow B in FIG. 2

Устройство состоит из корпуса 1, закрепленного на нем привода 2, соединенной с приводом т ги 3 с осью 4, на которой The device consists of a housing 1, a drive 2 fixed on it, connected to the drive train gi 3 with an axis 4, on which

10 шарнирно закреплен двуплечий прихват 5 с расположенными под углом 90° плечами, одно из которых периодически контактирует с обрабатываемой деталью 6, а сферическа головка второго - с отверстием 7, выполненным в подпружиненной части 8 установочного элемента, имеющей возможность продольного перемещени под воздействием пружины 9. Подпружиненна часть 8 снабжена упором10, закрепленным перпенди2д кул рно направлению перемещени установочного элемента. На корпусе 1 устройства жестко установлена неподвижна часть 11 установочного элемента.10. A double-arm hinge 5 with shoulders at an angle of 90 ° is hinged, one of which is periodically in contact with the workpiece 6, and the spherical head of the second is with a hole 7 made in the spring-loaded part 8 of the mounting element, which has the possibility of longitudinal movement under the influence of spring 9. The spring-loaded part 8 is provided with an abutment 10 fixed perpendicularly 2 coolly to the direction of movement of the mounting element. On the housing 1 of the device is rigidly fixed stationary part 11 of the installation element.

Claims

The device works as follows. When the part is unclamped, 6 t ha 3 under the influence of the actuator 2 moves from the part together with the two shoulder strap 5 and the axis 4. At the same time, the spring-loaded part of the adjusting element under the influence of the spring 9 remains in place; and the axis 4 reaches the stop 10, which retracts the spring-loaded part 8 from part 6. The part is completely released. When clamping the part 6, the axis 4, moving towards the part, releases the stop 10 and the spring-loaded part 8 under the influence of the spring 9 approaches the part 6 and orients it. In this case, the axis 4 departs from the stop 10 and rotates the clamp 5 to the contact of its shoulder with the part. Such an embodiment allows one to extend the technological capabilities of the device by carrying out orientation and clamping of the part in two mutually perpendicular directions from one drive. Claims of the invention A device for clamping parts comprising an adjusting element and a movable drive rod with an axis on which a two-armed strap is hinged, characterized in that, in order to expand technological capabilities by performing orientation and clamping of the part in two mutually perpendicular directions one actuator, the adjusting element is made of a fixed part and spring-loaded with a through hole, designed to accommodate one shoulder sticking in it, and the device is equipped with a stop fixed to the spring part of the mounting element and intended to interact with the thrust axis.
