Gripper device for maintaining, centring, and/or clamping a micromechanical or horological component, and associated fastening method

A gripper device (100) for maintaining, centring, and/or clamping a micromechanical or horological component (200) in a clamping chamber defined by a clamp including a plurality of jaws comprising at least one first mobile jaw (2), that is mobile radially with respect to a longitudinal axis of the clamp, and at least one second mobile jaw (2),

• wherein said at least one first mobile jaw (2) includes a reference surface (20) arranged for direct axial bearing of said component (200), and wherein said gripper device (100) includes at least one vacuum generator (60) arranged to create a vacuum in said clamping chamber via at least one channel (25) made in the at least one said mobile jaw (2), and
• wherein said at least one vacuum generator (60) includes a venturi cartridge positioned between an inlet circuit for blowing air via at least one blowing track (471, 472), and a suction zone (600) in which the vacuum transmitted to said clamping chamber by said at least one channel (25) is created during a blowing of air at an inlet, and
• wherein the gripper device (100) further includes an actuator device arranged to control opening or closing of said clamp and includes pushing means (50) on an elastic support, a closing or opening cone (30), including conical surfaces (32) arranged to cooperate with complementary surfaces (23) that said mobile jaws (2) include and which form surfaces for actuating said clamp.
