1one

Изобретение относитс к станкостроению и может быть испо«тьзовано дл закреплени обрабатываемых деталей.The invention relates to a machine tool industry and can be used to secure workpieces.

Известно устройство дл закреплени деталей, содер}| ащее корпус с базовыми элементами, установленный на оси рычаг с прижимным кольцом и зажимной элемент, св занный с приводом 1.A device for fixing parts, contents} | A common housing with base elements, an axle-mounted lever with a pressure ring, and a clamping element associated with the actuator 1.

Недостатком известного устройства вл етс низка точность обработки деталей, закрепленных в устройстве.A disadvantage of the known device is the low accuracy of machining of parts fixed in the device.

Цель изобретени - повышение точности обработки деталей.The purpose of the invention is to improve the accuracy of machining parts.

Указанна цель достигаетс тем,-что в устройстве зажимной элемент выполнен в виде закрепленных на штоке гвдроцилиндра прихвата с пазом и направл ющей планкой со скосами на ее концах, а также закрепленного на рычаге пальца с роликом, .причем палец предназначен дл взаимодействи с пазом прихвата, а ролик - с направл ющей планкой, при этом устройство снабжено штангой, а рычаг установлен с возможностью перемещени относительно последней и поворота вокруг ее оси.This goal is achieved by the fact that in the device the clamping element is made in the form of a clamp on a hydraulic cylinder rod with a groove and a guide bar with bevels at its ends, as well as a roller fixed on the lever of a finger, and the finger is designed to interact with the hook groove and a roller with a guide bar; the device is provided with a rod, and the lever is mounted for movement relative to the latter and turning around its axis.

На фиг. .1 изображено предлагаемое устройство ,, общий вид; на-фиг. 2 - разрез А-АFIG. .1 shows the proposed device, a general view; in FIG. 2 - section aa

на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1; на фиг. 4 - разрез В-В на фиг. 3. Устройство дл закреплени деталей содержит корпус 1, на котором установлены базовые элементы 2. В опорах 3, закрепленных на корпусе 1, размещена штанга 4, на которой установлен с возможностью перемещени вдоль нее и поворота вокруг ее оси рычаг 5, несущий кольцо 6. На рычаге 5 закреплен палец 7 с роликом 8. В корпусе 1 установлен гидроцилиндр 9, на штоке 10 которого размещена направл юща планка 11 и прихват 12 взаимодействующий при зажиме с пальцем 7 рычага 5. На корпусе установлен конечный выключатель 13. На направл ющей планке 11 выполнены ско15 СЫ 14.in fig. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3. The device for securing parts comprises a housing 1 on which the basic elements 2 are mounted. In the supports 3 fixed to the housing 1 a rod 4 is placed on which the lever 5 supporting the ring 6 is mounted for movement along it and turning around its axis. A finger 7 with a roller 8 is fixed on the lever 5. The hydraulic cylinder 9 is mounted on the housing 1, on the stem 10 of which a guide bar 11 is placed and a clamp 12 interacting with the clamp 7 of the lever 5. The body has a limit switch 13. On the guide bar 11 performed speed15 14.

Устройство работает следующим образом.The device works as follows.

Claims

In the initial position, the lever 5 is in the extreme right position, with this roller 8 fixed on the finger 7 of the lever 5 contacting the guide plane 11 and located on the bevel 14. The component force arising from the force of gravity when the roller 8 contacts beveling 14 presses the lever 5 to one of the supports 3, fixing it in the extreme position. After loading the workpiece, the lever 5 is moved along the rod 4 and the guide bar 11. At the end of the stroke, the roller 8 hits the second bevel 14 and presses the lever 5 to the support 3, fixing the latter in the working (leftmost) position, which is controlled by the limit switch 13 Next, oil is supplied to the cavity a, the hydraulic cylinders, the rod 10 is moved together with the guide bar 11 and the clamp 12. The lever 5 with the pressure ring 6 and the roller 8 in contact with the guide bar 11 rotates on the rod 4 until the pressure ring 6 contacts processing detail. The rod 10, continuing to move, leads the guide bar 11 out of contact with the roller 8, after which the clamp 12 seizes the finger 7 and through the lever 5 and the pressure ring 6 clamps the workpiece. After the part has been machined, the oil is fed into the cavity of the hydraulic cylinder 9. The rod 10 moves and removes the tack 12 from engaging with the finger 7. With further movement of the rod 10, the guide bar 11 approaches the roller 8 and moves it, and with it the lever 5, turning the latter relative to the bar 4, and pulls the clamping ring 6 from the workpiece. Then the lever 5 with the clamping ring 6 is retracted. The use of the invention improves the accuracy of machining parts fixed in the device. An apparatus for securing parts, comprising a housing with base elements, an lever with a clamping ring mounted on an axis, and a clamping element associated with an actuator, characterized in that in order to improve the accuracy of machining parts, the clamping element is designed as a sticking cylinder mounted on a brush. with a groove and a guide bar with bevels at its ends, as well as a finger fixed on the lever with a roller, the finger intended for engaging with the groove of the tack and the roller with the guide Lanka, wherein the apparatus is provided with a rod, and the lever is mounted to a stirred and rotation relative to the latter about its axis.
