Embodiment
Please refer to Fig.1 to Fig. 5, the inventor of the utility model in order to preferably to the technical solution of the utility model into
Row understands, is described in detail below by specifically embodiment, and with reference to attached drawing：
Referring to Fig. 1, the center for having nose end end face of turbine bolt 9 is mounting hole 91, mounting hole 91 can be countersunk head
Hole or through hole, the outside diameter that turbine bolt 9 has nose end end face are D2, and the internal diameter of mounting hole 91 is D1.
Refer to Fig. 2 and Fig. 3, a kind of positioner for turbine bolt vacuum heat of the utility model, bag
Include bottom plate 1 and be fixed on vertically on 1 top surface of bottom plate, for the column 2 with the socket of the mounting hole 91 of turbine bolt 9, bottom plate 1
It is horizontally fixed in vacuum drying oven, therefore, the length d1 of bottom plate 1, and the width d2 of bottom plate 1, be to should be less than vacuum drying oven bottom
The length and width in face.
The recirculation hole 3 excessively for heat-treatment medium overcurrent in vacuum drying oven is provided with bottom plate 1.
Column 2 and recirculation hole 3 excessively are arranged in arrays on bottom plate 1, and in the length direction in bottom plate 1 and width side
Upwards, column 2 and recirculation hole 3 excessively misplace uniformly distributed.
The thickness d 3 of bottom plate 1 is depending on the shove charge weight of turbine bolt 9.The diameter of phi d7 of recirculation hole 3 is crossed on bottom plate 1
