(54) УСТРОЙСТВО ДЛЯ УДАЛЕНИЯ ДЕТАЛЕЙ(54) DEVICE FOR REMOVING PARTS

1one

Изобретение относитс к машиностроению и может быть использовано в частности дл съема обработанных деталей с опорной поверхности зажимных приспособлений агрегатных и подобных им станков.The invention relates to mechanical engineering and can be used in particular for the removal of machined parts from the supporting surface of the clamping devices of modular and similar machines.

Известно устройство дл удалени деталей, содержащее корпус, подпружиненный сбрасыватель, установленный с возможностью возвратно-поступатель- ,fj ного перемещени в поворотной направл ющей , шарнирно закрепленной на корпусе , и штангу, расположенную вдоль направл ющей и соединенную с помощью траверсы с пневмоцилиндром lj. ,5A device for removing parts is known, comprising a housing, a spring-loaded ejector, mounted for reciprocating, fj movement in a pivoting guide hinged to the housing, and a rod located along the guide and connected to the pneumatic cylinder lj by means of a cross beam. ,five

Недостаток известного устройства заключаетс в том, что размещение траверсы с пневмоцилиндром ниже поворотного стола требует дл прохождени 2о толкател и рейки на каждой позиции стола дополнительных отверстий, а наличие отверстий в столе приводит к засорению стружкой толкателей, рейки.A disadvantage of the known device is that placing the crosshead with a pneumatic cylinder below the turntable requires 2o for pushing the pusher and the slats at each position of the table for additional holes, and the presence of holes in the table leads to clogging of the pushers and slats.

что влечет за собой их заклинивание/ Наличие в устройстве рычага и элементов его св зи со сбрасывателем и ползуном усложн ет конструкцию. Устройство также трудно переналаживаемо с одного типоразмера детали на другую.which entails their jamming / The presence of a lever in the device and elements of its connection with the ejector and the slide complicates the design. The device is also difficult to adjust from one part size to another.

Цель изобретени - повышение надежности устройства.The purpose of the invention is to increase the reliability of the device.

Поставленна цель достигаетс тем, что штанга снабжена поводком, конец которого выполнен вилкообразной формы и соединен со сбрасываетелем, установленным с возможностью качани в вилке поводка, и регулируемым упором, причем на направл ющей выполнен клинообразный выступ дл взаимодействи с упом нутым упором.The goal is achieved by the fact that the rod is provided with a leash, the end of which is fork shaped and connected to a resetter mounted with a swing in the fork fork and an adjustable stop, with a wedge-shaped protrusion on the guide for interacting with said stop.

Claims

The device for removing parts consists of a diverter 1 placed in a guide 2, which is connected to the housing 3 by a hinge and spring 5c with an actuator bracket 6, the role of which can, for example, be performed by a pneumatic cylinder. The guide 2 has a projection 7 with a bevel. Through the pin 8 on the ejector, it is connected by a fork 9 of the leash 10 to a rod 11 mounted on the traverse 12 of the drive 6 and equipped with an adjusting stop 13 located in its upper part. The traverse 12 is interoperable with the levers 1 of the jigs and fixed stops 15 The device works as follows . When the crosshead 12 moves, the pneumatic scaffold rod down, the leash 10 with its fork 9 through the pin 8 pulls down the resetter 1. At the same time, the stops 15 and the adjustable stop 13- move downwards with the crosshead. When the arm stops are pressed, the part at the drop position is released from fastening and At the loading position, an opening is opened for supplying a new billet. During the further course, the adjustable stop 13 comes into contact with the protrusion 7i, slides along the bevel, deflects the guide 2 on the hinge 4, and with it the ejector with the detail in the side direction. During the return stroke of the pneumatic cylinder rod, the rod 11 releases the guide 2 from the action of the adjustable stop 13 and under the influence of the spring 5, the guide 2 together with the resetter 1 returns to its initial position. The table is rotated and installed with its working position with the clamping levers H clamped under the part under the ejector, and the position free from the part — in front of the loading magazine. The use of the proposed device will reduce the amount of stroke of the rod, and hence the time for unclamping a fixed part and its withdrawal. An improvement in the design arrangement and an increase in its reliability are achieved, since the translational and oscillatory movements of the lever ejector are carried out from a single drive rod, which is brought out of the zone where the chips hit it in the upper position. In addition, due to the possibility of adjusting the stop on the rod, the device is versatile and can remove and remove parts of different sizes. Claims An apparatus for removing parts, comprising a housing, a spring-loaded ejector, mounted for reciprocating movement in a rotary guide hinged to the housing, and a rod located along the guide and connected by means of a crosspiece with a pneumatic cylinder, characterized in that in order to increase reliability, the rod is provided with a leash, the end of which is made of a fork shape and connected to a diverter installed with the possibility of swinging in the tail fork, and reg a locating abutment, wherein a wedge-shaped protrusion is made on the guide to cooperate with said abutment.
