Hole probe apparatus |
摘要 |
In an automatic fastening machine 10 comprising a frame 12 for operating a workpiece 16 along a work centerline and having a drilling tool for drilling a hole in the workpiece, a bucking ram 26, and a milling tool 30 having a hole inspection assembly 22 mounted on the upper ram 88 thereof. The hole inspection assembly includes a hole probe assembly 24 that is movable axially along the work centerline to insert a probe member 25 into a position inside the hole in the workpiece. The probe is provided with a plurality of capacitor plates 25B that measure the peripheral extent of the hole to insure that the hole is drilled within a tolerance range and is also properly positioned on the workpiece before a fastener is inserted. The probe assembly has several proximity limit switches 138 and 152 that detect movement between a cylinder bracket 72 biased to a probe connector 74 to signal a central processor 300 to discontinue axial movement of the probe along the work centerline should the probe contact the workpiece or a foreign object before it locates properly inside the hole.
