Abstract
The utility model provides a kind of adjustable pre-stressing heat treatment frock, comprising: v block, tail rod, screw rod and base; Be fixedly connected with base respectively with below tail rod below described screw rod, above screw rod and tail rod above respectively with v block running fit; Described screw rod top is provided with steel ball, and steel ball top contacts with v block; Wherein, described tail rod can fix the position of the horizontal direction of v block; Described screw rod can regulate the height of the vertical direction of v block.The beneficial effects of the utility model are: have the advantages such as structure is simple, easy to use, of many uses, long service life.
Description
Technical field
The utility model belongs to heat treatment tooling apparatus technical field, particularly relates to a kind of adjustable pre-stressing heat treatment frock that can control and regulate stepped axle class heat treatment deformation.
Background technology
In industrial machinery structure, the stepped shaft-like workpiece of normal needs, because quenching technology postorder process redundancy is little, so will control the deflection in heat treatment of workpieces process.Prior heat treatment frock is: directly use v block pave unsettled for workpiece or be directly positioned in dull and stereotyped frock by workpiece level; although these two kinds of traditional methods can both ensure the level of workpiece; but due to the deadweight of the STRESS VARIATION in heat treatment process and workpiece; often there will be workpiece deformation in heat treatment process overproof, and due to technical problems such as the special not easily alignments of workpiece shapes.
Utility model content
It is simple and can the adjustable pre-stressing heat treatment frock of controlling and adjustment heat treatment deformation amount that problem to be solved in the utility model is to provide a kind of structure, is especially suitable for stepped shaft-like workpiece.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: adjustable pre-stressing heat treatment frock, comprising: v block, tail rod, screw rod and base; Be fixedly connected with base respectively with below tail rod below described screw rod, above screw rod and tail rod above respectively with v block running fit; Wherein, described tail rod can fix the position of v block horizontal direction; Described screw rod can regulate the height of v block vertical direction;
Further, described screw rod can regulate v block at the height of vertical direction by rotary motion;
Further, described screw rod top is provided with steel ball, and steel ball top contacts with v block;
Further, be connected with whorl of base respectively with below tail rod below described screw rod;
Further, described tail rod by nut and base fastening.
The advantage that the utility model has and positively effect are: adopt technical scheme described in the utility model,
1, workpiece is in quenching heat treatment process, the distance at v block and stepped shaft-like workpiece low order position is controlled by screw rod, calculate the coefficient of expansion in advance in advance, the deformation distance in tolerance zone is reserved between workpiece and v block, after workpiece STRESS VARIATION in quenching process is expanded, the unlikely frock that is subject to is to workpiece externally applied forces, and the distortion that workpiece self gravitation in without frock situation simultaneously also can be avoided to cause is overproof.
Even if 2, large-scale shaft workpiece exist after quenching heat treatment process distortion overproof, also the utility model can be used when tempering to deformation ruler little progress Row sum-equal matrix: by overproof for shaft-like workpiece upper limit position upwards, under v block is padded on axle, make workpiece unsettled, Heating temperature when utilizing tempering and workpiece deadweight, namely be equivalent to apply external force to the overproof position of the workpiece upper limit in a heated state, thus adjustment workpiece deformation size, make its deformation amount controlling in tolerance zone.
In addition, the utility model also has the advantages such as structure is simple, easy to use, of many uses, long service life.

Fig. 2 is the utility model A-A face sectional view.
In figure:
1, workpiece; 2, v block; 3, tail rod; 4, steel ball; 5, screw rod; 6, nut; 7, base.
Embodiment
As Figure 1-Figure 2, the utility model provides a kind of adjustable pre-stressing heat treatment frock, comprising: v block 2, tail rod 3, screw rod 5 and base 7; Be fixedly connected with base 7 respectively with below tail rod 3 below described screw rod 5, above screw rod 5 and tail rod 3 above respectively with v block 2 running fit; Wherein, described tail rod 3 can fix the position of v block 2 horizontal direction; Described screw rod 5 can regulate the height of v block 2 vertical direction;
Described screw rod 5 can regulate v block 2 at the height of vertical direction by rotary motion;
Described screw rod 5 top is provided with steel ball 4, and steel ball 4 top contacts with v block 2;
Be threaded with base 7 respectively below described screw rod 5 He below tail rod 3;
Described tail rod 3 is fastening by nut 6 and base 7.
The working process of this example: operator's hand rotation screw rod 5, regulate v block 2 vertical distance to workpiece interval budget distance; Then by adjustable pre-stressing heat treatment frock and workpiece 1 together shove charge carry out quench treatment; The deflection of measuring workpieces 1 after quench treatment, during adjustment tempering v block 2 vertical distance to workpiece interval budget distance, by adjustable pre-stressing heat treatment frock and workpiece with stove tempering.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
