Abstract
A dimpling device is provided with a slide rod, a first workpiece holder, and a second workpiece holder. The slide rod is slidably fitted around a center pin running through rivet holes. The first workpiece holder is slidably and detachably fitted around the slide rod. The second workpiece holder is detachably fixed to the center pin. The first and second workpiece holders have holding surfaces with curvatures that have been preselected to conform to the curvatures of the surfaces of workpieces. The slide rod has a punch and the second workpiece holder has a die. When the workpieces are held together by the holding surfaces, a nut is rotated to move the punch into a cooperative relationship with the die, thereby dimpling the surroundings of the rivet holes.
