Method for carrying out stress tests pins. It works on the principle of manual hydraulic jack (10) embedded in the full groove bottom plate (6). With the hand lever stroke can be vertical movements of a piston which presses against the lower intermediate piece (8). The lower part of the spacer is associated with an internal thread dial gauge (9). This will set in motion the upper intermediate piece (7) opposite a dial indicator (9). The other side of dial gauges (9) is also associated with the upper threaded joint intermediate piece (7). The upper intermediate piece (7) moves the movable assay plates (4) in the axial direction. Movable assay plate (4) is covered against lateral slipping plate (5) which is welded to a solid test plate (3). Assay plate of the movable plate (4) in the vertical direction slide on the cutting of the pin is provided with upper stops (2), which is welded to the two supporting posts, the higher the stability of the entire construction (1). |
