    摘要： In an automatic fastening machine 10 including 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.

    摘要： A method and apparatus for positioning tooling and riveting the apparatus including a frame provided with opposed riveting rams (96, 86) and clamps (34, 36). The first clamp (34) is extended above the work plane established by the outer surface of one workpiece (10) with the lower ram retracted. Next, the frame (26) is moved downwardly until the first clamp touches the workpiece. An encoder (140) measured the amount of first clamp collapse during overtravel of the frame after the first touch is sensed. The frame is now backed off this distance to establish a work line coextensive with the work plane. The lower clamp (36) is then raised to clamp the workpieces (10, 12) and drill carried by a sub-frame (66) will now drill aligned apertures through the workpieces. The subframe is indexed to another position to place rams (96, 86) is alignment with the apertures. The upper riveting ram (96) is then advanced to its full down position to set an upper cavity and is locked under high pressure. The lower ram (86) then rises under low pressure to a snug up position. Squeeze forming is now accomplished by simultaneously controlled motion of the frame down and the lower ram up until an upset complete signal is received. During this operation the upper clamp (34) is in a resilient condition. When the rivet is completely upset pressure is dumped from the upper clamp and simultaneously the frame is driven to its start position and the lower ram is retracted. As soon as the lower ram reaches its back away position the upper riveting ram is fully retracted.

    摘要： A method and apparatus for inserting fasteners which are press fit through aligned apertures in side-by-side workpieces. The apparatus includes a frame which is moveable relative to the side-by-side workpieces, the frame including a main frame and a subframe mounted on the main frame and moveable between the first and second positions. The subframe carrys tooling in the form of a drill and an upper ram. Also, mounted on the main frame are upper and lower spaced apart clamps which may be selectively moved into contact with upper and lower surfaces of upper and lower workpieces. The upper ram can be moved into contact with a headed fastener to force the shank of the fastener through aligned apertures drilled in the workpieces. A vibrating apparatus is associated with the upper ram and will be operated to hammer the upper ram while it is still being maintained in contact with the fastener after the fastener has been inserted into the workpieces to fully insert the fastener and relieve any stresses which may be present. Subsequently a collar may be swaged about the end of the fastener which projects through the workpieces.
