Specific implementation mode
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, meticulously describes, but the scope of protection of the utility model is not limited to embodiment in detail below.
Shown in Fig. 1-Fig. 3, a kind of heat treatment tooling embodiment of hollow shaft of motor train unit of the utility model, including bottom
Seat 1, the top of pedestal 1 are equipped with multiple extend straight up and are used to support the cross being positioned in the endoporus of pending hollow shaft 7
Shape positioning column 2 is equipped with interval between multiple cross positioning columns 2.The utility model is equipped with multiple cross on pedestal and positions
Column, in use for combining closely with the bottom of hollow shaft and endoporus, on the one hand can fix product makes it not shake,
It can guarantee the product stability in heat treatment process, reduce the probability mutually collided between product, improve product quality；On the other hand
Tooling weight can effectively be reduced.
In the present embodiment, there are four cross positioning column 2 is set, four cross positioning columns 2 are arranged to square structure.Cross
The bottom of shape positioning column 2 is equipped with supporting surface 21, and difference in height h is equipped between the supporting surface 21 of adjacent cross positioning column 2, the height
Poor h does not generate interference with the blade 71 in adjacent vacant mandrel 7 to be advisable.The structure that this height interlocks can make after hollow shaft shove charge it
The blade stagger at top is put so that the tooling, which takes up space, to be substantially reduced, to reduce the making weight and system of tooling
This is caused, saves the space in burner hearth to make batch increase.
In the present embodiment, cross positioning column 2 is welded by steel plate, and top is the arc transition of evagination.Cross
The periphery of positioning column 2 is fitted close with the endoporus of hollow shaft 7, and the height of cross positioning column 2 is that can prevent hollow shaft 7 from shaking
The dismounting of hollow shaft 7 can be facilitated to be advisable again.In general, the height of cross positioning column is higher, hollow shaft is less susceptible to send out after shove charge
Raw double swerve, but the difficulty that the hole of hollow axis center is inserted in cross positioning column when shove charge is bigger, is unfavorable for product handling；
And the height of cross positioning column is lower, easier shaking after hollow shaft shove charge, but it is easier by hollow axis center when shove charge
Hole be inserted in boss.
In the present embodiment, pedestal 1 be by the steel plate weld all around arranged vertically at frame-shaped structure, each side of frame-shaped structure
Outside is additionally provided with an outline border 11, and frame-shaped structure is internally provided with crisscross steel plate reinforcing rib 5；Four cross positioning columns
2 bottom end is welded in the top four corners of frame shape pedestal 1.Pedestal uses steel plate structure, and is taken under normal conditions whole
The scheme that hole is cut on body steel plate is compared, and has not only been reduced tooling overall weight but also has been reduced manufacturing cost, while also having ensured
Pedestal possesses enough intensity.
Further include a connecting hoisting device 4 in the present embodiment, cross positioning column 2 is located at the interior of connecting hoisting device 4
Portion.Connecting hoisting device 4 includes two inverted U-shapeds that type is integrally bent by round steel, and two inverted U-shapeds are symmetrical arranged,
Two vertical edge inside bottoms of inverted U-shaped are welded in the outside of outline border 11.And it is set between two vertical edges of inverted U-shaped
Have three for reinforcement cross bar 3, wherein two cross bars 3 can be also used for preventing hollow shaft 7 during lifting set on middle part
Rollover breaks furnace wall, and is equipped with decussation bar 6 as reinforcement, for limiting inverted U-shaped between two cross bars 3
Arc lifting boom and cross bar occur bending and deformation after the heating, by gravity, solve unidirectional connection, local support, one
As spacing heat treatment tooling the problem of can not effectivelying prevent being affected by gravity deformation after the heating for intersecting.In the utility model
Connecting hoisting device is integrally bent into type by round steel, and no-welding-seam, riveted seam and splicing seams will not be during heat treatment because of heating
And connecting portion cracking, separation is led to problems such as to close and fall and occur.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment.To those of ordinary skill in the art, gained under the premise of not departing from the utility model technical concept
To modifications and variations also should be regarded as the scope of protection of the utility model.
