Title:
VICE CLAMP PRESSURE DETECTING DEVICE
Document Type and Number:
Japanese Patent JP2001129735
Kind Code:
A
Abstract:

To provide a compact vice clamp pressure detecting device capable of being easily adjusted.

When a work W is clamped with predetermined pressure by a vice device 3, the pressure of the pressure oil supplied to a clamp side cylinder chamber 11 of a fluid pressure cylinder 7 of the vice device 3 is equalized to the pressure of the pressure oil from a hydraulic pump P, but the areas of a detection cylinder 17 receiving the pressure are different between one side thereof connected to the clamp side cylinder chamber 11 or the hydraulic pump P, and the other side by a cross-sectional area of a piston rod 25, so that the detection cylinder 17 is moved by the difference of the pressure force to turn a switching means 47 on or off. As the detection cylinder 17 is mounted integrally with a manifold 5, and the switching means 47 is mounted on the manifold 5 by a screwing means, a position of the switching means 47 can be easily adjusted.
