Abstract
A tool for centering and clamping of at least a part (P) to be fixed in position and comprising a through passage and adjusted for the tool, comprises a pilot device borne at the end of a case having an upper face forming a support for the part and clamping members. The tool further comprises elements for driving the clamping members between a centering position in which the clamping members are retracted into the pilot device and a plurality of clamping positions in which the clamping members project outside the pilot device and rest on the part (P). The driving elements are arranged for simultaneously pivoting and translating the clamping members between the centering position and the clamping position. The invention is useful for handling parts to be fixed in position.
Claims8
A centering and gripping tool for at least one piece to be fixed in position and comprising a through-passage and being suitable for said tool, the tool comprising:
- a guide member carried at the end of a casing having an upper surface forming an abutment for said piece and gripping members;
- drive means for driving the gripping members between a centered position in which the gripping members are retracted within the interior of the guide member and a plurality of gripping positions in which the gripping members project outside the guide member and bear on the piece;
- said drive means being structured and arranged to drive simultaneously pivotally and in translation said gripping members between the centered position and a gripping position;
- said gripping members comprising two levers articulated about a median axis to form a deformable X;
- each lever having a first end having abutment means and a second end opposite said abutment means connected to the drive means such that, under the influence of said drive means, said second ends are movable in translation, by moving together or apart, the first ends of said levers being then driven simultaneously in pivoting and in translation because of the deformation of the X formed by said levers.
