Abstract
Disclosed herein is apparatus for testing the weld strength of a battery connection extending through a hole in a battery partition and between first and second lugs located in adjacent parallel relation to the partition and each including an end surface and a pair of side surfaces extending in parallel relation to each other and in transverse relation to the end surface, which apparatus comprises a vertically movable main frame including a holding surface adapted for engagement with the end surface of the first lug, a sub-frame carried by the main frame and movable vertically relative to the main frame, horizontally movable clamping members carried by the sub-frame for clampingly engaging the side surfaces of the second lug to the sub-frame, a cylinder for applying a force for vertically displacing the main frame to engage the holding surface with the end surface of the first lug and to retain the holding surface against vertical movement after engagement with the end surface of the first lug, a second cylinder for applying a force for horizontally displacing the clamping members to clampingly engage the second lug to the sub-frame, and a third cylinder for applying a force for vertically upwardly displacing the sub-frame while maintaining the sub-frame in clamping engagement with the second lug and while maintaining the holding surface in engagement with the end surface of the first lug and against vertical movement, whereby to subject the connection to shearing stress.
