Abstract
A base assembly for use with a riveting apparatus such as an electromagnetic riveter (EMR). In one aspect of the invention, the base assembly includes a base plate (42) having a raised beveled portion (80) extending upwardly from the upper surface (54) of the base plate (42). A mounting plate (72) fits on and is secured to the base plate (42) by a plurality of coil springs (90-93). The mounting plate (72) has a recessed portion (66) in the lower surface thereof which mates with the raised portion (80) of the base plate (42). Trip switches (104-107) are positioned in the mounting plate (72) for detection of movement of the mounting plate (72) relative to the base plate (42) in response to undesired contact between the EMR and a part assembly or fixture therefor. An output signal indication is provided when one or more of the trip switches (104-107) are actuated. In another aspect of the invention, a base assembly mounting plate (152 ) is mounted on mounting studs (168-171) and locating pins (156, 158) which extend upwardly from a base member (154). An EMR is mounted on the mounting plate (152). Spring washers 180-183 are located between the mounting plate (152) and the base member (…
