Abstract
The utility model discloses a kind of connecting rod hook anti-deformation heat treatment tooling, belong to heat treatment tooling field.It includes base, jig, the base is provided with multiple rows of mutually spaced jig, the jig is made up of short supporting surface, long support face and inclined-plane, short supporting surface, long support face are fixed on base vertically, inclined-plane both ends at the top of short supporting surface, long support face respectively with being connected, angle between inclined-plane and short supporting surface is identical with the bending angle of connecting rod hook, connecting rod hook, which is brought into close contact, is placed on inclined-plane, on short supporting surface, and hollow hole is equipped with the short supporting surface, long support face and inclined-plane.Connecting rod hook, which is brought into close contact, is placed on inclined-plane, on short supporting surface, and under the glowing furnace condition of high temperature, connecting rod hook is not in deformation, and bending angle meets tolerance；Hollow hole is equipped with short supporting surface, long support face and inclined-plane, when high temperature quenches, cooling of the quenching oil to connecting rod hook is not influenceed, ensures the quenching degree of connecting rod hook.
Description
Technical field
A kind of connecting rod hook anti-deformation heat treatment tooling is the utility model is related to, belongs to heat treatment tooling field.
Background technology
Connecting rod hook in high-grade low voltage switch, it is a steel stamping part, has a bending, bending in the middle part of connecting rod hook
The tolerance of angle is very high, because connecting rod hook quality is heavier, no matter keeps flat or hangs, under glowing furnace high temperature state
It will be deformed, bending angle does not meet tolerance, then after oil groove quenches, can produce substantial amounts of defective work.It is logical
Design specialized frock is crossed, allows the fitting of connecting rod hook to be placed on special tooling, eliminates influence of the weight to deformation, product qualification rate is big
Width improves, and qualification rate is close to 100%.
The content of the invention
Technical problem to be solved in the utility model is：A kind of connecting rod hook anti-deformation heat treatment tooling is provided, it is solved
When the connecting rod in electric switch of having determined is hooked in high temperature quenching, easily deform, the problem of bending angle does not meet tolerance.
Technical problem to be solved in the utility model takes following technical scheme to realize：
A kind of connecting rod hook anti-deformation heat treatment tooling, it includes base, jig, and the base is provided with multiple rows of mutual
Spaced jig, the jig are made up of short supporting surface, long support face and inclined-plane, short supporting surface, long support face
Be fixed on vertically on base, inclined-plane both ends are connected with short supporting surface, at the top of long support face respectively, inclined-plane and short supporting surface it
Between angle it is identical with the bending angle of connecting rod hook, connecting rod hook, which is brought into close contact, is placed on inclined-plane, on short supporting surface, the short support
Hollow hole is equipped with face, long support face and inclined-plane.
The beneficial effects of the utility model are：The folding of angle and connecting rod hook between the inclined-plane of jig and short supporting surface
Bending angle is identical, and connecting rod hook, which is brought into close contact, is placed on inclined-plane, on short supporting surface, and under the glowing furnace condition of high temperature, connecting rod hook will not
Deform, bending angle meets tolerance；Hollow hole is equipped with short supporting surface, long support face and inclined-plane, is quenched in high temperature
When fiery, cooling of the quenching oil to connecting rod hook is not influenceed, ensures the quenching degree of connecting rod hook.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Base 1, jig 2, short supporting surface 21, long support face 22, inclined-plane 23, hollow hole 24, connecting rod hook 3.
Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of connecting rod hook anti-deformation heat treatment tooling, it includes base 1, jig 2, set on base 1
There are multiple rows of mutually spaced jig 2, jig 2 to be made up of short supporting surface 21, long support face 22 and inclined-plane 23, short branch
Support face 21, long support face 22 are fixed on base 1 vertically, the both ends of inclined-plane 23 respectively with short supporting surface 21, the top of long support face 22
It is connected, the angle between inclined-plane 23 and short supporting surface 21 is identical with the bending angle of connecting rod hook 3, and connecting rod hook 3 is brought into close contact
It is placed on inclined-plane 23, on short supporting surface 21, hollow hole 24 is equipped with short supporting surface 21, long support face 22 and inclined-plane 23.
Angle between the inclined-plane 23 of jig 2 and short supporting surface 21 is identical with the bending angle of connecting rod hook 3, connecting rod hook
3 be brought into close contact be placed on inclined-plane 23, it is short support 21 faces on, under the glowing furnace condition of high temperature, connecting rod hook 3 be not in deformation, folding
Bending angle meets tolerance；Hollow hole 24 is equipped with short supporting surface 21, long support face 22 and inclined-plane 23, is quenched in high temperature
When, cooling of the quenching oil to connecting rod hook 3 is not influenceed, ensures the quenching degree of connecting rod hook 3.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within the utility model will
In the range of asking protection.The utility model requires protection scope is by appended claims and its equivalent thereof.
