Title:
ACCELERATION TESTING MACHINE
Document Type and Number:
Japanese Patent JP2005337881
Kind Code:
A
Abstract:

To provide an acceleration testing machine enhanced in reproducibility and improved in workability.

The acceleration testing machine has a lower pressurization terminal placing an object to be treated, which has a plating film on its surface, on its upper surface, an upper pressurization terminal which obtains elastic force by a spring to press the object to be treated on the lower pressurization terminal, a base part for supporting the lower pressurization terminal, a pressurization adjusting bolt rotated by forward and reverse rotary operation to bend the spring by forward rotation and a support mechanism for supporting the pressurization adjusting bolt and the upper pressurization terminal and is so constituted that the support mechanism presses the object to be treated by definite pressurizing force until setting is released after the object to be treated on the lower pressurization terminal is set so as to be held by the upper pressure terminal and the center part of the region where the object to be treated is pressed is positioned on the extension of the center axis of the pressurization adjusting bolt. The acceleration testing machine also has a rotation preventing mechanism for suppressing the rotation of the upper pressurization terminal and the spring and a bending quantity measuring mechanism for reading the bending quantity of the spring. A housing part for housing the lower pressurization terminal or a load cell capable of measuring pressurizing force is provided to a base part. The thickness of the lower pressurization terminal is set to the same dimension as the thickness of the load cell.
