Description

  The present invention relates to a vane erecting attachment device that erects vanes such as a plurality of nozzle vanes supplied from a vane supply device and sequentially attaches them to a plurality of support holes of a base ring member.

  When assembling a variable nozzle unit (see Patent Document 1) in a variable capacity turbocharger, a vane standing mounting apparatus may be used. The configuration of a conventional vane standing mounting apparatus will be described as follows.

  That is, an index table that supports the base ring member is rotatably disposed around a vertical axis in a region separated from the outlet side of the vane supply device. The plurality of support holes of the base ring member can be sequentially indexed to the reference mounting position by rotation.

  A vane erecting mechanism for erecting the nozzle vane is disposed on the outlet side of the vane supply device. Specifically, a rotating body is provided on the outlet side of the vane supply device so as to be rotatable around a horizontal axis, and a first vane shaft formed on one end surface of the nozzle vane is provided on the rotating body. A holding tool for standing is provided. Here, the standing holder is configured to move between a fall rotation position that becomes a lying posture and a standing rotation position that becomes a standing posture due to the rotation of the rotating body.

  A vane attachment mechanism for attaching the nozzle vane to the support hole of the base ring member is disposed between the index table and the vane standing mechanism. Specifically, an elevating body is provided between the index table and the vane standing mechanism so as to be able to move up and down. Further, the elevating body is provided with a slider movably in the horizontal direction, and this slider is provided with a mounting holder for holding the second nozzle shaft formed on the other end face of the nozzle vane. Here, the mounting holder is moved between a position facing the reference mounting position and a position facing the standing rotation position by the horizontal movement of the slider.

  Therefore, by holding the first vane shaft of the nozzle vane by the standing holder located at the fall rotation position, and rotating the rotating body in the positive direction around the horizontal axis, the standing holder can be moved from the fall rotation position. The nozzle vane is erected (moved from the lying posture to the standing posture) by moving (positioning) to the standing rotation position. Next, the elevating body is lowered, and the second vane shaft of the nozzle vane is held by the mounting holder located at the position opposite to the standing rotation position. And a nozzle vane is lifted from the vane standing mechanism side by raising a raising / lowering body.

  After the nozzle vane is lifted from the vane standing mechanism side, the rotating body is rotated in the reverse direction around the horizontal axis, thereby returning the standing holder to the overturning rotation position. Further, the slider is moved in the horizontal direction, and the mounting holder is moved (positioned) from the position opposed to the standing rotation position to the position opposed to the reference mounting position. Then, the lifting body is lowered to bring the mounting holder closer to the support hole of the base ring member indexed to the reference mounting position, thereby inserting the first vane shaft of the nozzle vane into the support hole of the base ring member. The nozzle vane is attached to the support hole of the base ring member. Before the elevating body is lowered, the index table is rotated around the vertical axis, and the support hole of the base ring member is indexed to the reference mounting position.

  After attaching the nozzle vane to the support hole of the base ring member, the lifting body is raised and the slider is moved in the horizontal direction to return the attachment holder to the position opposite to the upright rotation position.

  By repeating the above-described operation, the plurality of nozzle vanes can be attached to the plurality of support holes of the base ring member.

  In addition, there exists a thing shown in patent document 2 as a prior art relevant to this invention.

  A plurality of nozzle vanes V can be sequentially attached to the plurality of support holes Wh of the shroud ring W by repeating the operation after the preparation for the attachment of the nozzle vanes V is completed.

  In short, each rotating claw 69 of the standing rotating body 71 is provided with a standing air chuck 79 that sucks and holds the first vane shaft Va of the nozzle vane V, and the vane standing mechanism 65 is rotated by 180 degrees rotation of the standing rotating body 71. When one of the standing air chucks 79 is positioned at the standing rotation position RP, the other standing air chuck 79 is positioned at the lying down rotation position DP. The next nozzle vane V can be erected without reciprocating between the upright rotation position RP and the overturning rotation position DP. In addition, after the nozzle vane V is mounted, the next nozzle vane V is shroud ring W without reciprocating the mounting air chuck 59 between the facing position FMP of the reference mounting position MP and the facing position FRP of the upright rotation position RP. Can be attached to the support hole Wh.

  Therefore, according to the second embodiment, as in the first embodiment, the tact time for raising and attaching the nozzle vane V can be greatly shortened, and the productivity can be sufficiently increased.

  The present invention is not limited to the description of the above-described embodiment. For example, instead of the shroud ring W, a nozzle ring is attached to a support hole of another base ring member such as a nozzle ring, or the nozzle vane V Instead, other various vanes such as a diffuser vane may be installed in the support hole of the base ring member, and various other modes may be implemented. Further, the scope of rights encompassed by the present invention is not limited to these embodiments.
