(54) ИСКУССТВЕННАЯ КИСТЬ(54) ARTIFICIAL BRUSH

жен электромеханический нривод а виде электродвигател  4 с редуктором 5 и выходной парой винт-гайка 6. Кроме того, искусственна  кисть содержит рычажный механизм в виде кривошипа 7 с осью, подпружиненного переключател  8 с фигурным вырезом 9, подпружиненного кулачка 10 с упором 11 и планки 12. На планке 12 укреплен кронштейн 13 с шарнирно установленной на нем кулисой 14 со стойкой 15, расположенной в центре кулисы и соединенной с первым пальцем 2, а конец кулисы 14 шарннрно соединен с кривошипом 7.Electromechanical actuators for electric motor 4 with gear 5 and screw-nut output pair 6. In addition, the artificial brush contains a lever mechanism in the form of a crank 7 with an axis, a spring-loaded switch 8 with a figured notch 9, a spring-loaded cam 10 with an emphasis 11 and a bar 12 On the bracket 12, a bracket 13 is fixed with a link 14 which is hinged on it with a stand 15 located in the center of the link and connected with the first finger 2, and the end of the link 14 is connected with the crank 7.

Устройство работает следуюш,им образом .The device works in the following way.

При выполнении электродвигателем 4 раскрыти  пальцев редуктор 5 посредством выходной пары винт-гайка 6 и кривошипа 7 приводит в движение кулису 14, стойка 15 которой движетс  по пазу 16 первого пальца 2, поворачива  палец в сторону раскрыти . При этом ось кривошипа 7 поворачивает кулачок 10. Кулачок отходит от упора 11, расфиксиру  блок 3 2-5 пальцев.When the electric motor 4 opens the fingers, the reducer 5 by means of an output pair of screw-nut 6 and crank 7 drives the slide 14, the pillar 15 of which moves along the groove 16 of the first finger 2, turning the finger in the direction of opening. In this case, the axis of the crank 7 rotates the cam 10. The cam moves away from the stop 11, releasing the block with 3 2-5 fingers.

Ь то же врем  ось кривошипа 7, дойд  до конца пр молинейного паза 17, входит под действием пружииы 18 в фигурный вырез 9 переключател  8 и перемещает его. Переключатель, в свою очередь, перемеш,ает блок 3 2-5 пальцев до полного раскрыти , которое ограничено крайним положением хода гайки редуктора.At the same time, the axis of the crank 7, reaching the end of the rectilinear groove 17, enters under the action of the spring 18 into the figure-cut-out 9 of the switch 8 and moves it. The switch, in turn, is shuffled, a block of 3 2-5 fingers until it is fully opened, which is limited by the extreme position of the stroke of the gearbox nut.

По достижении крайнего положени  двигатель затормаживаетс  и его необходимо выключить.When the extreme position is reached, the engine is braked and must be turned off.

При включении электродвигател  4 на схват пружина 18 посредством переключател  8 перемещает блок 3 1-5 пальцев в сторону закрыти  до контакта блока с предметом .When the motor 4 is turned on, the spring 18 by means of the switch 8 moves the block 3 1-5 fingers in the direction of closing until the block contacts the object.

Одновременно кривошип 7 посредством кулисы 14 перемещает первый палец 2 в сторону закрыти  и посредством т ги 19 поворачивает кулачок 10 в сторону упора 11 дл  последующей фиксации блока 3.At the same time, the crank 7 moves the first pin 2 in the direction of closure through the wings 14 and rotates the cam 10 in the direction of the stop 19 in order to fix the block 3.

При встрече с предметом сопротивление на концах пальцев блока 3 превышает силу пружины 18, удерживающей ось кривошипа в фигурном вырезе 9 переключател  8. Ось выходит из фигурного выреза и далее скользит по пр молинейному пазу 17 переключател , вследствие чего блок 3 2-5 пальцев отключаетс  от электропривода посредством кулачка 10 и упора 11 с планкой 12 и шатуном 20 блок 3 2-5 пальцев фиксируетс  в достигнутом положении.When it encounters an object, the resistance at the ends of the fingers of the block 3 exceeds the force of the spring 18 holding the crank axis in the figure 9 of the switch 8. The axis comes out of the figure notch and then slides along the straight slot 17 of the switch, as a result of which the block 3 2-5 fingers disconnect from the electric drive through the cam 10 and the stop 11 with the bar 12 and the connecting rod 20, the block 3 2-5 of the fingers is fixed in the position reached.

При дальнейшем движении кривошип 7 поворачивает только первый палец 2 (посредством кулисы 14).Upon further movement of the crank 7 turns only the first finger 2 (by means of the scenes 14).

В результате того, что блок 3 2-5 пальцев отключен, усилие, развиваемое двигателем , перераспредел етс , воздейству  теперь только на основание первого пальца. Введение кулисы 4 между кривошипомAs a result of the fact that the block 3 2-5 of the fingers is disconnected, the force developed by the engine is redistributed, and now I only act on the base of the first finger. The introduction of the scenes 4 between the crank

7 и основанием первого пальца 2 позвол ет увеличить плечо действи  усили  от электродвигател  и достичь передаточного отношени  механизма схвата, равного 1:1, что обеспечивает повышение силы схвата7 and the base of the first finger 2 allows the force of the force from the electric motor to be increased and the gear ratio of the gripper is 1: 1, which increases the gripping force

на концах пальцев до величины усили , развиваемого электродвигателем на гайке редуктора. Увеличение же хода гайки редуктора дл  перемещени  дополнительного рычага достигает лишь 0,5 раза.at the ends of the fingers to the magnitude of the force developed by the electric motor on the gearbox nut. Increasing the stroke of the gearbox nut to move the additional lever reaches only 0.5 times.

Предлагаема  искусственна  кисть позвол ет увеличить разнообразие предметов, доступных схвату, за счет увеличени  силы схвата.The proposed artificial brush allows an increase in the variety of objects available to the gripper by increasing the gripping force.
