Abstract:
An alignment device for a tire laser mapping machine having a hub on which a tire is mounted, a shaft connected to the hub, a laser probe, and a rail for moving the laser probe across the tread of the tire to map the tire when it is mounted on the hub; said alignment device being shaped and sized to be mounted on the hub in place of the tire and comprising a series of connected walls forming alignment surfaces S1-S5 shaped and positioned so that when the laser probe is moved across the alignment surfaces:the mapping of the alignment surface S1 and the mapping of the alignment surface S2 correspond to the perpendicularity of the laser relative to the rail in a first direction and a second direction perpendicular to the first direction; the mapping of the alignment surface S2 and the alignment surface S3 will correspond to the parallelism of the rail to the shaft in the first and second directions; and the mapping of the alignment surface S4 and the alignment surface S5 will correspond to radial and out-of-plane wobble.
