摘要
An apparatus for changing rim sets at a testing station of a tire uniformity testing system that includes a storage unit for storing a plurality of rim set assemblies. A transfer arm is reciprocally movable and includes a gripper mechanism for gripping a rim set assembly and moving it from a storage position to a position at which rims forming part of the rim set assembly are aligned with opposed spindles at the testing station. The rim set assembly includes a bracket having structure engageable by the transfer arm and at least one of the rims forming part of the assembly includes a locking member rotatable between a first position and a second position. The bracket includes a structure for immobilizing the rim to inhibit relative rotation between the rim and the bracket and further includes a lever mechanism for moving the locking member from its first position to its second position in order to engage retaining members forming part of the bracket. The lever mechanism moves the locking member from its second position to its first position when the rim is aligned with an associated spindle in order to engage other retaining members forming part of the spindle. The rim is released from the bracket as the locking member moves to engage the other retaining members. After release, the bracket moves to a remote position spaced from the testing station. To remove the rim sets, the steps for attaching rims to the spindles are reversed in order to release the rims from the spindles while simultaneously engaging the bracket. The resulting rim set assembly is moved to a remote position defined by a storage unit that stores a plurality of rim set assemblies. The disclosed locking member and associated rim can be used to facilitate the manual installation of a test rim to a spindle.
