Title:
補償システムを有するクランピングツール、特に溶接プライヤー
Document Type and Number:
Japanese Patent JP5033427
Kind Code:
B2
Abstract:
A clamping tool comprises first and second clamping components (18, 20) able to be displaced relative to each other by a drive device made up of: (A) a screw (10), able to rotate around an axis (XX) in opposing directions by means of a motor (M), with a nut (12) co-operating with the screw and which can be rotated in the direction of the axis of the screw, the screw being coupled in translation to the first clamping component; (B) a first guidance mechanism (34L) defining linear guidance parallel to the axis of the screw to rotationally block the nut in a first phase of nut displacement; (C) a second guidance mechanism (34H) defining helicoidal guidance extending according to the axis of the screw and which has an inverted thread in relation to that of the screw to enable the nut to rotate in the same direction as the screw in a second nut displacement phase; (D) in addition a compensation system (46) is arranged between the first clamping component and a mobile suppor! t (14) coupled to the nut to re-initialise the position of the first clamping component in relation to the second clamping component, such that the first and second displacement phases remain synchronous with the phases which are required to optimise displacement of the first clamping component.
