Patent ID: 10544813

Abstract:
An electrical clamping apparatus is provided that can reduce an entire size using a motor as a driving source and largely improve a grip torque by applying a sliding crank portion and a changed toggle link portion with a driving force transfer mechanism. The electrical clamping apparatus for clamping and fixing one side of a panel includes a main body; a driving motor installed within the main body and that generates a driving force; a clamp portion that clamps or unclamps the panel; a toggle link portion connected to the clamp portion and that transfers rotatory power to the clamp portion to rotate the clamp portion; a driving force transfer portion connected to the driving motor to transfer a driving force of the driving motor to the toggle link portion; and a sliding crank portion connected to one side of the toggle link portion to convert a rotational motion of the driving force transfer portion to a linear reciprocating motion and to operate the toggle link portion in a state in which one side thereof is connected to the driving force transfer portion and in which the other side thereof is vertically bent toward the toggle link portion.
