<p>An alignment adjusting mechanism secures and adjusts the alignment of a magazine ((10) which retains a plurality of sensing elements (12) within the working area of a coordinate measuring machine) relative to the bed of a machine on which the magazine is mounted. The mechanism comprises a plate (20), rigidly connected to the bed, and a base (18), which supports the magazine (10) secured to the bed of the machine via the plate (20); the base (18) is resiliently secured to the plate (20) by bolts (26), washers (27) and disc springs (30). The bearing end of a grub screw (40) engages a conical recess (46), thus providing a pivot point for pivoting of the base (18) relative to the plate (20). Two further pairs of grub screws (34) and (48) bear against the plate (20). Adjustment of the attitude of the base (18) about the axes (56) (the roll), (54) (the pitch), and (58) (the yaw) is achieved using the grub screws (34,40,48).</p> |
