PURPOSE:To test a test piece while displaying it in two axial directions simultaneously by connecting a position adjusting mechanism which incorporates a parallel link mechanism to a fixed-side and an oscillation-side test piece fitting base and a test piece coupling plate. CONSTITUTION:A test piece fitting base 11 is mounted on the internall wall surface of a ceiling plate 2 to clamp test pieces W1 and W2 across the coupling plate 13 between the base 11 and a test piece fitting base 7 on a table 3. The position adjusting mechanism 15 including the parallel link mechanism composed of a link arm 22 is connected to both test piece fitting bases and coupling plate. When an actuator is put in expanding and contracting operation to press up a piston rod 5, the test pieces W1 and W2 are compressed and also drawn to left by the operation of the link arm 22. Similarly, when the piston rod 5 is lowered, tensile force and leftward force are applied tod take a test of two-axial displacement with the driving force of one axis. |
