1. An apparatus for quality inspection of shafts, comprising:
a rotary table provided with cutout grooves disposed at an outer periphery thereof at a predetermined pitch, and configured to receive neck portions of headed shafts supplied from the work feeder in the respective cutout grooves, and to convey the headed shafts while being suspended by the rotary table; and an inspection station disposed at an intermediate portion of a conveyance path to be formed by the rotation of the rotary table; wherein the inspection station includes a camera configured to capture images of the headed shafts being conveyed, from radially outward of the rotary table; wherein the rotary table comprises: an upper disk and a lower disk stacked in a vertical direction so as to be rotatable relative to each other; and plate members provided in the same number as the cutout grooves, each having a same thickness as the upper disk; wherein first cutouts each defining each of the cutout grooves are provided at an outer periphery of the upper disk, and second cutouts each corresponding to each of the first cutouts are provided at an outer periphery of the lower disk; wherein each of the plate members is inserted in each of the first cutouts, and fixed to an upper surface of the lower disk; wherein each of the cutout grooves has a first groove edge and a second groove edge facing, respectively, forward and rearward in a direction in which the table rotates, wherein one of the first and second groove edges is defined by one of side edges of each of the first cutouts; and the other of the first and second groove edges is defined by one of side edges of each of the plate members; wherein each of the second cutouts is formed as an angular groove including side edges which are parallel to each other and located forward and rearward in the direction in which the table rotates, and an end edge perpendicular to the side edges of each second cutout; and wherein a distance between the side edges of each second cutout is set to be larger than a maximum groove width of each of the cutout grooves, whose width can be adjusted. |
