PURPOSE: To improve ease of use by forming a clamping member and a clamp end member so as to be capable of moving and being fixed on a pair of guide axles, fitting a retaining jaw on one side of the clamping member and a clamp jaw elastically-supported on the other side.
CONSTITUTION: The multiple chucking fixture is provided with clamp blocks 10 fixed on a pair of guide axles, and a plurality of clamping members 20, 20'... and a clamp end member 30 journaled so as to move and fixed with precision of 1/100 mm. In the respective clamping members 20, 20'..., a retaining jaw 11 is rigidly mounted for 0 point movement at the end face on one side, and a clamp jaw 21 is elastically-supported with a coil spring 24 on the other side to clamp a plurality of works 35. It is thus possible to fit various shapes and sizes of works easily and use the overall length of an existing machine table completely.
