Clamping arrangement for CT measurements with a play-free joint

摘要

Clamping arrangement (1) for computed tomography (= CT) measurements, comprising a workpiece (3) and a workpiece holding arrangement (2) in which the workpiece (3) is held, characterized the workpiece holding arrangement (2) is formed with a first leg (9) and a second leg (10) which are connected to one another via a play-free joint (11), wherein in a region (12) of front ends of the legs (9, 10) the workpiece (3) is clamped, wherein in a region (14) of rear ends of the legs (9, 10) an at least partially made of metal spring means (13) is arranged, which acts on the legs (9, 10), and that the two legs (9, 10) are made of a non-metallic holding arrangement material, and the workpiece (3) is made of a workpiece material at least in a partial section (16) close to the legs (9, 10) . wherein the holding assembly material has an X-ray attenuation coefficient (42) that is less than or equal to a coefficient of attenuation of the workpiece material.
