Abstract
A shaker table comprises upper and lower plates spaced apart by a plurality of spacers that fit between the plates. Each spacer has an upper shaft, which threads into a vibrator opening in the upper plate, and a lower coaxial shaft, which slides into a vibrator opening in the lower plate. The spacer has a threaded internal coaxial opening extending through the spacer. A bolt for securing a vibrator to the bottom of the table engages the internal opening and secures the vibrator and the lower plate to the spacer and upper plate. A mounting bolt for attaching a test product or test fixture to the top of the table threads into the internal opening from the top.
Claims8
A shaker table comprising:
- an upper plate on which a test product is mounted, the upper plate having a plurality of vibrator mounting openings therein;
- a lower plate spaced below the upper plate, the lower plate having a plurality of vibrator mounting openings therein that are aligned with vibrator mounting openings in the upper plate;
- a plurality of spacers mounted between the plates, the spacers each having a central portion positioned between the plates, a upper shaft extending upwardly therefrom, and a lower shaft extending downwardly therefrom, the upper and lower shafts fitting respectively in the corresponding vibration mounting openings in the upper and lower plates, the central portion abutting the upper and lower plates so as to space the plates a predetermined distance apart, the shafts having concentric axial openings therein that extend into the central portion, the openings being threaded;
- fastener means for securely mounting the spacers to the upper plates;
- and
- fastener means for mounting vibrators to an underside of the lower plate, said fastener means including threaded fasteners that extend through openings in the vibrators and engage the threaded internal openings in the lower shafts, the fastener means thereby serving to attach the lower plate to the spacers and the upper plate.
