Изобретение относитс к автооператорам предназначенным дл автоматизации производственных процессов в приборостроении, радиоэлектронике, производстве химических источников тока, в частности к вакуумным захватам.The invention relates to auto operators intended to automate production processes in instrumentation, electronics, the production of chemical current sources, in particular, to vacuum grippers.

Известен вакуумный захват, содержащий корпус и подвижно установленные относительно него присосные камеры, соединенные с источником вакуума, упор, дтрикрепленный к корпусу и коромысло, соединенное с упором и присосными камерами 1.A vacuum grip is known, comprising a housing and suction chambers movably mounted relative to it, connected to a vacuum source, an abutment attached to the hull and a rocker arm connected to the abutment and suction chambers 1.

Недостатком известной конструкции вакуумного захвата вл етс то, что его функциональные возможности ограничены, а именно, он не обеспечивает захват деталей повышенной жесткости, так как осуществл ет сложный изгиб захватываемой детали относительно трех точек (упора и двух присосов ). При работе с детал ми, имеющими вор систую или загр зненную поверхность, такой захват требует затрат времени на профилактическую чистку, так как не исключена возможность засорени плунжерной пары.A disadvantage of the known vacuum gripping design is that its functionality is limited, namely, it does not capture the details of increased rigidity, since it performs a complex bending of the gripped part relative to three points (the stop and two suckers). When working with parts that have a thief or a dirty surface, such a grip requires time spent on prophylactic cleaning, since the possibility of clogging of the plunger pair is not excluded.

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

Дл достижени этой цели вакуумный захват снабжен планками, установленными одними концами подвижно в вертикальном пазу, выполненном в упоре, а другими щарнирно прикрепленными к коромыслу, которое выполнено из двух частей, шарнирно присоединенных к упору, при этом присосные камеры соединены с источником вакуума посредством сильфонов.To achieve this goal, the vacuum gripper is provided with strips mounted one end movably in a vertical groove made at the stop, and others hingedly attached to the rocker arm, which is made of two parts hinged to the stop, while the suction chambers are connected to the vacuum source by means of bellows.

На фиг. 1 представлен захват в положении «подход к детали, .общий вид; на фиг. 2 - захват в положении «захват детали , общий вид.FIG. 1 shows the grip in the position “approach to detail, general view; in fig. 2 - capture in the position of “capture details, the general view.

Вакуумный захват имеет корпус 1, на упоре 2 которого общей осью 3 закреплено коромысло, состо щее из двух шарнирно сочлененных частей 4, на которых установлены присосы 5. Присосы соединены с вакуумными каналами на корпусе через сильфоны 6. Дл одновременного и равномерного отклонени частей 4 коромысла на них ос ми 7 закреплены планки 8, имеющие общую ось 9, свободно перемещающуюс по направл ющему пазу на упоре корпуса. Угол поворота планок с присосами регулируетс гайками 10.The vacuum grip has a housing 1, on the support 2 of which a common axis 3 is fixed to a rocker, consisting of two articulated parts 4, on which suckers 5 are mounted. Suction cups are connected to the vacuum channels on the body through bellows 6. For simultaneous and uniform deviation of the 4 rocker arms On them, axes 7 are fixed with strips 8 having a common axis 9, freely moving along a guide groove on the body support. The angle of rotation of the suction bars is adjusted by nuts 10.

Claims

Vacuum capture works as follows. The vacuum is turned on. The grip is lowered until the abutment 2 and the suction cups 5 are in contact with the stack of parts, while the suction cups capture the upper part 11 in the stack. The outflow of air through the suction stops, the vacuum in the gripping system increases and the bellows 6 is compressed, unfolding the strips 4, as well as the strips 8 up to the stop against the adjusting nut 10. The part held by the suction cups And deforms (the deformation shape of the part depends on the geometric dimensions of the gripping elements) relative to the stop 2 and separated from the foot. The vacuum gripper rises and transfers the retained part to the assembly position. The vacuum is turned off, the bellows is ejected under the action of elastic forces, the bars are unfolded, dropping the part. The vacuum pickup is then returned to its original position and the cycle of operation is repeated. The use of a vacuum grip, with the ability to adjust the angle of Rasis and tSUOMU / TLllUV-I D iripvyuivri | i i / i u J gates and exposing the suction cups relative to the stop on the housing, as well as the use of bellows to connect the suction cups with vacuum channels, provides an increase in the functionality and reliability of the grip. Fast readjustment of the grip to a new part, simplification of the shape-deformation (only relative to the stop) of the captured part, insensitivity to contaminated media gives high utilization efficiency and economic effect due to unification of this type of grips, expansion of the range of captured parts (parts of increased rigidity, with a fleecy and soiled surface) and reducing the time spent on prophylactic cleaning, the claims of the invention Vacuum gripper comprising a housing and movably mounted relative On it, suction chambers connected to a vacuum source, an emphasis attached to the body, and a rocker arm connected to the anvil and suction chambers, characterized in that, in order to increase reliability, it is provided with slats installed with one ends movably in a BepTHKavTbHOM groove made in the rest, and others, hingedly attached to the beam, which is performed f1 -. but in two parts, hingedly attached to the support, with the suction chambers connecting ......, - h-chg tl1-chr | P1 111 / l and 1 chl 1 / O ll AGM-.1 P Ы are not with a vacuum source by means of bellows.
