Blower fan main shaft heat treatment tooling
Technical field
The utility model belongs to technical field of heat treatment technology, solves the blower fan main shaft heat treatment tooling that main shaft distorts in heat treatment process when particularly relating to blower fan main shaft thermal treatment.
Background technology
Watt level blower fan main shaft belongs to the key part of small-sized wind power generator, and require that comprehensive mechanical property is higher, finished product form and position tolerance is stricter.In order to ensure the mechanical property of main shaft, general employing chain lifts separately heat-treats.But this processing mode efficiency is low, and workpiece easily bends.This is the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and the few undistorted thermal treatment realizing multikilowatt blower fan main shaft provides a kind of blower fan main shaft heat treatment tooling.
For solving the problems of the technologies described above, the technical solution of the utility model is blower fan main shaft heat treatment tooling, it is characterized in that: this frock comprises bottom support dish, midfeather dish, top hoisting ring, described bottom support dish, midfeather dish, top hoisting ring and column are connected in series, described midfeather dish arranges one group of through hole, described bottom support dish arranges one group of riser.
Further improvement of the utility model has, and described one group of through hole at least arranges two, and its diameter is greater than major axis diameter, and is distributed on midfeather dish.
Further improvement of the utility model has, and will leave gap between described one group of riser, its length can not be greater than described bottom support dish.
Compared with prior art, the beneficial effects of the utility model are: adopt this frock to carry out the thermal treatment of blower fan main shaft, can guarantee that main shaft is in heating and cooling process, remain upright state, chassis is adopted to add the structure of space disc, guarantee that blower fan main shaft keeps a determining deviation when thermal treatment shove charge, make main shaft when Q-tempering heating and cooling evenly, more abundant, thus reduce distortion.Guaranteeing that heating and cooling are uniform while, reduce the possibility of main shaft distortion to the full extent, thus realize the few undistorted thermal treatment of main shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, Fig. 2 utility model works view.
In figure: the hoisting ring of 1-top, 2-midfeather dish, 3-column, 4-through hole, 5-riser, 6-bottom support dish, 7-main shaft, 8-heat treatment tooling.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Can be found out by accompanying drawing, blower fan main shaft heat treatment tooling, it is characterized in that: this frock comprises bottom support dish 6, midfeather dish 2, top hoisting ring 1, described bottom support dish 6, midfeather dish 2, top hoisting ring 1 are connected in series with column 3, described midfeather dish 2 arranges one group of through hole 4, described bottom support dish 6 arranges one group of riser 5.Described one group of through hole 4 at least arranges two, and its diameter is greater than main shaft 7 diameter, and is distributed on midfeather dish 2.Will leave gap between described one group of riser 5, its length can not exceed described bottom support dish 6.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
