Tab welded turntable

摘要

A turntable assembled from a plurality of flat sheet metal parts where the sheet metal parts include a series of voids and/or protrusions. The protrusions insert into the voids so that some flat sheet parts are disposed in a vertical orientation and some in a horizontal orientation, the vertical parts substantially perpendicular to the horizontal parts. The flat sheet parts are welded together to create a support structure with the voids and protrusions interacting to align the flat sheet parts within required manufacturing tolerances. One of the horizontally disposed parts has holes therein for attaching the support structure to a hub to create a rotating turntable.

1. A turntable comprising:
a hub having a plurality of holes; said holes adapted to receive bolts for affixing the hub to a foundation; and a support structure attached to said hub, said support structure comprising:
a plurality of horizontal members having a plurality of voids, the plurality of voids including at least a first and second row of voids the first and second row of voids each including at least two of the plurality of voids;the first row of voids extending along a first direction, the second row of voids extending along a second direction perpendicular to the first direction;a plurality of vertical members each of said vertical members disposed between and substantially perpendicular to said horizontal members, at least two of said plurality of vertical members perpendicular to each other;a protrusion extending from an edge of each said vertical members, said protrusion inserted into one of said voids; andsaid vertical members joined to said horizontal members.
