【発明の名称】圧力媒体で操作可能なトグルレバ-式締付け装置
Document Type and Number:
Japanese Patent JPS608167
Kind Code:
B2
Abstract:
A fluid-operated clamping device comprises a support forming a cylinder in which a piston is reciprocatable. A piston rod fixed to piston has a free end projecting beyond the cylinder. A bell crank is pivotally mounted on a portion of the support extending beyond the cylinder. A clamping arm is preferably releasably connected to one arm of the bell crank and has a V-shaped end portion extending transverse to the remainder of the clamping arm adapted to clamp a sheet metal or the like between the V-shaped end portion and a matching V-shaped notch on the upper surface of a stationary anvil. A link comprising at least one spring plate partly divided by a preferably T-shaped slot extending from one side thereinto into two resilient end portions is arranged between the free end of the piston rod and the other arm of the bell crank with one end portion pivotally connected to the free end of the piston rod and the other end portion pivotally connected to the other arm of the bell crank. The springy link will not only permit construction of the device with relatively large tolerances, but will also prevent excessive clamping forces during operation of the device.
