摘要： An analogue probe has a fixed structure and a stylus supporting member connected to the fixed structure by three serially mounted pairs of leaf springs interconnected by first and second intermediate members. The stylus supporting member supports an elongate stem upon which a cube, which supports three scales, is mounted. Readheads are mounted on the fixed structure, in register with the scales, to transduce movement of the stylus supporting member in three substantially orthogonal directions. The alignment of the scales about the yaw axis (extending in a direction perpendicular to the plane of the scale) determines the alignment of the measuring axes of the probe, while the straightness of the lines of the scales determines the straightness of the axes.

摘要： An analogue probe 100 includes a fixed structure 110 and a stylus supporting member 112 suspended relative to the fixed structure 110 by three serially connected pairs of leaf springs 114,116,118. Displacement of the supporting member 112 relative to the fixed structure 110 is transduced by three opto-electronic scale and readhead transducers 136,144;138,146;140,148. The distorting effect of bending moments applied to the tip 130 of the stylus 128 upon leaf springs 114,118 is counteracted by an increased spacing between upper ends of leaf springs of a given pair, relative to the spacing between leaf springs at their lower ends; the resulting arrangement forming a trapezium as opposed to a rectangle. This enables longer styli to be employed before distortion of the leaf springs causes failure of the opto-electronic transducers due to unwanted tilting of the supporting member 112.

摘要： A connecting device for connecting a shank 16 to a measuring probe 18 is disclosed, to enable the probe 18 to be incorporated on a machine tool for the purpose of tracing a contour of a model. The device includes first and second parts (20,22) connected to the shank and the probe respectively, retained together by a connecting bolt 50 which is spring-loaded by means of Belville washers 56. An arm 60 extends from the second part to engage the housing 14 of the spindle 10, and thereby prevent rotation of the spindle shaft 12. In the event of accidental spindle start-up the two parts 20,22 may rotate relative to each other (the shank rotating with the shaft 12); a thrust bearing 42 enabling sliding of the two parts.
