Floating clamp device

The utility model relates to a floating clamp device which comprises a guide sleeve, a pull rod, a self-lubricating guide sleeve, a cushion block, a spring, a screw rod, a bottom plate, a cover plate, a base plate, a clamping plate, a clamp base, a jackscrew, a finger block, fingers, a guide block and a proximity switch. The finger block is fixed on the finger, the finger is connected with the clamp base through a screw, the clamp base and the clamping plate are pre-tightened through a jackscrew, and the bottom plate is connected with the guide column through a screw rod; the pull rod penetrates through the clamp base to be in threaded connection with the guide block. When a workpiece is clamped, the device changes the position of the proximity switch through the compression spring to achieve grabbing signal recognition. The guide column, the guide sleeve and the spring are converted into a movable clamp mechanism, so that signal judgment is formed by signal change of the proximity switch when a workpiece is
