Изобретение относитс к медицине, а именно к протезированию и к протезостроению , и касаетс протезов верхних конечностей.The invention relates to medicine, in particular to prosthetics and to prosthetic engineering, and concerns upper limb prostheses.
Известно устройство дл схвата, содержащее механизм управлени в виде блока с двум выступами, рычага, микровыключател и т ги, электродвигатель с двум выходными концами вала, соединенные с этими концами винтовой и черв чный редукторы, причем черв чный редуктор соединен с концрм вала посредством разъемной муфты, а также имеет упругую пластину со втулкой, установленной на валу черв чного колеса, и две бранши в виде пластин с отверсти ми, одна из которых соединена с гайкой винтового редуктора а друга - с валом черв чного колеса UlОднако данное устройство не совершает поворот бранш вокруг стержн независимо, что снижает функциональность .A device for a gripper comprising a control mechanism in the form of a block with two protrusions, a lever, a microswitch and a pull, an electric motor with two output shaft ends connected to these ends of a screw and a worm gearbox is known, and the worm gear is connected to the shaft end by a detachable coupling It also has an elastic plate with a sleeve mounted on the shaft of the worm gear, and two jaws in the form of plates with holes, one of which is connected to the nut of the screw gearbox and the other to the shaft of the worm gear Ul. This device does not rotate the branches around the rod independently, which reduces functionality.
Цель изобретени - расширениеThe purpose of the invention is the expansion
числа активных функций и осуществленle сзсвата предметов сложной формы.the number of active functions and implemented with the subject of complex forms.
С указанной целью электродвигатель соединен с винтовым редуктором по средством разъемной муфты с подвикной частью, муфта черв чного редуктора имеет две подвижные части, при1ем одна из них оснащена подп тником, выполненным в виде корпуса, в кот )10 ром установлена пружина и подшипник качани с обоймой, блок снабжен дополнительным третьим выступом,For this purpose, the electric motor is connected to a helical gearbox by means of a detachable coupling with a subwire part, the worm gearbox coupling has two movable parts, one of which is equipped with a bushing made in the form of a housing, a spring and a swing bearing with a yoke , the unit is provided with an additional third protrusion,
гиК рычагу прикреппена вилка, контак рующа с подвижной частью муфты в a hook is attached to the lever, contacting the movable part of the coupling in
1НJ5 тового редуктора.1NJ5 tovogo gear.
Кроме того, одна из бранш выпо In addition, one of the branches is
1нена в виде клина, а отверстие выпо Iнено со стороны остри клина.1nen in the form of a wedge, and the hole is in the direction of the point of the wedge.
