Strain gage device and method

摘要

A strain gage device and method for positioning and applying strain gages in vehicles includes an alignment jig for fixing a position relative to a cylinder bore in an engine block, a rotatable member selectively rotatable relative to the alignment jig to a desired angular position, and at least one arm pivotally mounted to the rotatable member for applying a strain gage to the engine block.

1. A strain gage device for positioning and applying strain gages in vehicles, comprising:
an alignment jig for fixing a position relative to a cylinder bore in an associated engine block; a rotatable member selectively rotatable relative to the alignment jig to a desired angular position; and at least one arm pivotally mounted to the rotatable member for applying a strain gage to the associated engine block, the at least one arm having at least one end spaced apart from the rotatable member for carrying the strain gage, the at least one arm pivotable about the rotatable member to radially move the at least one end relative to an axis of rotation of the rotatable member for applying the strain gage at a location spaced apart axially from the rotatable member; and a locking device for locking an angular position of the rotatable member relative to the alignment jig, wherein the locking device includes:
at least one alignment jig aperture defined by the alignment jig;at least one rotatable member aperture defined by the rotatable member, wherein the rotatable member is rotatable to position the at least one rotatable member aperture in registry with the at least one alignment jig aperture; anda pin receivable through the at least one alignment jig aperture and the at least one rotatable member aperture when in registry with one another to lock the angular position of the rotatable member relative to the alignment jig, andwherein the at least one alignment jig aperture is a plurality of apertures disposed in circumferentially spaced relation to one another about a central circular aperture defined by the alignment jig in which the rotatable member is received.
