A shot treatment device includes, a rotary table rotatable in a first rotation direction about a first rotation shaft extending along a vertical direction, a plurality of placement tables arranged at intervals in a circumferential direction on an upper surface of the rotary table, an ejector configured to eject shot media, a first inspection detector configured to inspect surface properties of a workpiece, a shot chamber in which shot media is ejected to a workpiece, and a first inspection chamber provided downstream in the first rotation direction from the shot chamber. The ejector ejects shot media to a workpiece held on a first placement table that has entered the shot chamber, and the first inspection detector capable of ascending and descending is disposed above a second placement table that has entered the first inspection chamber and inspects surface properties of a workpiece held on the second placement table.

Shot treatment device

A machine for centrifugally shooting abrasives that shoots the abrasives by rotation of an impeller is provided. In the machine, the impeller comprises a pair of disc-shaped side plates that face each other at a predetermined distance and a plurality of blades disposed between the side plates in the radial direction of the side plates. The impeller is mounted on a hub that is fitted into an output shaft of an electric motor. The impeller is covered by a cover. The side liner and blades of the machine can be easily replaced. A side linerthat is U-shaped with the longer side facing downward is detachably attached to the inner side of the cover. The upper part of the side liner is divisible into two parts. The side liner protects the side wall of the coverfrom the abrasives that are shot from the impeller. The side liner has a U-shaped cross section. The impelleris fixed to the hubby screwing a bolton the hubfrom the inner sides of the side plates. The diameter of the impelleris limited to be 200 mm at maximum.

Machine for centrifugally shooting abrasives

A centrifugal projecting machine having a house, a driving device disposed at a first side of the housing with a flange, an impeller having a plurality of blades, wherein the impeller is connected to a driving shaft of the driving device with a hub, a distributor disposed in an inner cylindrical space of the impeller so that it is concentrically arranged in relation to the driving shaft, wherein the distributor has slit-like openings that are circumferentially disposed with substantially equal clearances, a control cage having an opening around a distal end for dispersing shot, wherein a proximal end surface of the control cage is connected to the second side of the housing, opposite its first side, around an opening for an intake disposed at its second side, wherein he control cage is disposed with a clearance between inner ends of the blades and an outer surface of the distributor and extends over the length of the impeller, and a nozzle connected to the second side of the housing to supply the opening for an intake with shot, wherein a supporting member is disposed at the side of the impeller to support the rotating impeller, or a rotating member for sealing is disposed between the proximal end of the distributor and the distal end of the control cage, or a bearing is disposed at the clearance between the inner periphery of the flange and an outer periphery of a hub together with damping members.
