Miniature Scissor Lift
Miniature Scissor Lift
(OP)
Dear all,
I need to design a miniature electric scissor lift. Generally, it must be no larger than about 30 mm X 20 mm and a extended height of 10 mm. Minimum height is of a high importance and must be equal or less than (if possible) 5 mm. This lift must fold. Therefore, a screw actuator is needed.
My question, is it possible to find a linear actuator miniature enough to fit into the mechanism. Moreover, how could I calculate the diameter of scissor arms that can support predetermined force (100 N) on the upper plate when the scissor lift is expanded.
Thank you in advance,
Shaban

EdDanzer, the change of piezoelectric materials as a response of the applied voltage is too small - of the order 10e-3 mm. As I told before, the change must be between 5 and 10 mm.

Thank you.

Plus needless to say if I could design such a thing I'd be off designing artificial hands and the like.

RE: Miniature Scissor Lift
Exactly, that's all I need to know. Is there any miniature linear actuator that could fit in the aforementioned scissor mechanism and could provide such a force?
