Description

Изобретение относитс к медицинской технике , а именно к протезированию и протезостроению .The invention relates to medical technology, namely to prosthetics and prostatic engineering.
Известна искусственна кисть, содержаща корпус, двуплечий рычаг первого пальца, блок 2-5 пальцев, св зующее звено, механизм схвата и усилитель схвата в виде втулок , упоров, , фиксатора, осей и эксцентрика , выполн ющий функцию дожати .An artificial brush is known, comprising a housing, a two-arm lever of the first finger, a block of 2-5 fingers, a coupling link, a gripper mechanism and a gripper amplifier in the form of sleeves, stops,, clamp, axes and an eccentric, performing the function of the dozhat.
Кисть обеспечивает фиксацию пальцев только в положении максимального раскрыти . Однако окончательна сила схвата определ етс жесткостью пружины усилител схвата и неизменна. Кроме того, отсутствует фиксаци пальцев в любом положении.The hand holds the fingers only in the maximum open position. However, the final gripper force is determined by the spring stiffness of the gripper reinforcement and unchanged. In addition, there is no fixation of the fingers in any position.
Цель изобретени - устранить эти недостатки .The purpose of the invention is to eliminate these disadvantages.
Дл этого механизм схвата и усилитель схвата выполнены в виде приводного рычага с пружиной, кулачком и роликом и второго плеча рычага первого пальца с наружной и внутренней криволинейными рабочими поверхиост ми .For this, the gripper mechanism and the gripper amplifier are made in the form of a driving lever with a spring, cam and roller, and the second lever arm of the first finger with external and internal curvilinear working surfaces.
На чертеже изображена предлагаема искусственна кисть, разрез.The drawing shows the proposed artificial brush cut.
Искусственна кисть содержит корпус /, двуплечий рычаг 2 первого пальца, блок 3 2-5 пальцев, св зующее звено 4. Механизм схвата и усилитель схвата выполиены в виде приводного рычага 5 с пружиной 6, кулачкомArtificial brush contains body /, double-arm lever 2 of the first finger, block 3 2-5 fingers, linking link 4. The gripper mechanism and gripper amplifier are molded in the form of a driving lever 5 with a spring 6, a cam
7 и роликом 8 и второго плеча 9 рычага 27 and roller 8 and the second shoulder 9 lever 2
первого пальца с нарулсной 10 и внутреннейfirst finger with 10 and inner
11 криволинейными рабочими поверхност ми.11 curvilinear working surfaces.
После контакта пальцев с предметом илиAfter contact of fingers with an object or
между собой второе плечо 9 двуплечего рычага 2 вместе с пальцами останавливаетс , а приводной рычаг 5 продолжает поворачиватьс в сторону пальцев и приводит в соприкосновение кулачок 12 с наружной W криволииейпой рабочей поверхностью. Двуплечий рычаг 2 первого пальца досылаетс пружиной 13 в сторону сгибани пальцев с больщим коэффициентом передачи силы на концы пальцев , превыщающей в 2-3 раза предварительную силу схвата. При этом параметры механизма подобраны такими, что происходит самозаклинивание и пальцы фиксируютс от непроизвольного раскрыти . Если второе плечо 9 двуплечего рычага 2 остановить опоройbetween each other, the second arm 9 of the two shoulders lever 2 stops together with the fingers, and the drive lever 5 continues to turn towards the fingers and brings the cam 12 into contact with the outer W curve of the working surface. The double-shouldered lever 2 of the first finger is removed by the spring 13 in the direction of flexing the fingers with a large force transmission coefficient at the ends of the fingers, 2-3 times more than the pre-gripping force. At the same time, the parameters of the mechanism are chosen such that self-jamming occurs and the fingers are fixed against involuntary opening. If the second shoulder 9 two shoulders arm 2 stop support
о предмет только первым пальцем или группой 2-5 пальцев, то есть до полного контакта их с предметом, и ири этом продолжать расслабл ть пальцевую т гу J4, то механизм схвата сработает на дальнейщее сгибаниеAbout the object only with the first finger or a group of 2-5 fingers, i.e., until they are completely in contact with the object, and then continue to relax the finger of J4, then the gripping mechanism will trigger further bending
пальцев, не обеспечива силового эффекта. Конечна сила схвата в этом случае будет минимальной, равной величине предварительной силы схвата, создаваемой при полном контакте пальцев с предметом до наступлеии fingers without a force effect. The final gripping force in this case will be minimal, equal to the value of the preliminary gripping force created by the full contact of the fingers with the object before the onset.
эффекта дожати .Doge effect.
Произвольно измен опорой пальцами о предмет степень его сжати до наступлени фазы дожати , можно регулировать конечную величину силы схвата от минимальной до максимальной.By arbitrarily changing the degree of its compression with the fingers against the object before the onset of the dozhat phase, you can adjust the final value of the gripping force from minimum to maximum.
Полностью раскрытые пальцы сначала фиксируютс опорой о предмет, затем, когда при расслаблении т ги срабатывает механизм схвата, кулачок 7 западает в углубление 15 второго плеча 9 и застопорит пальцев . Последующей выборкой пальцевой т ги 14 можно осуществл ть дальнейшее движение пальцев.Fully opened fingers are first fixed with a support on the object, then, when the gripper mechanism is triggered when the string is relaxed, the cam 7 sinks into the recess 15 of the second shoulder 9 and locks the fingers. Subsequent sampling of the finger grip 14 can further carry out the movement of the fingers.
