Transfer apparatus of testing master block for measuring machine

Abstract

A transfer apparatus of a testing master block for a coordinate measuring machine which enables a testing master block to be transferred on to a measurement table of the measuring machine quickly without human intervention and can be easily attached to an existing measuring machine with a small installation space, provided with a moving member for moving a testing master block for a measuring machine between a retracted position near an end of a measurement table of the measuring machine and a measurement position on the measurement table. When measuring a workpiece, the moving member or testing master block is retracted to a retracted position to enable the measurement table as a whole to be made effective use of in the measurement work. Between measurement operations of workpieces, the testing master block can be quickly moved and transferred to the measurement position to inspect the accuracy of the measuring machine itself or check the operation.
