The invention has the beneficial effects as follows: there is the advantage such as simple in construction, easy to use, of many uses, long service life.
Description
Technical field
The invention belongs to heat treatment tooling apparatus technical field, particularly relate 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, often need stepped shaft-like workpiece, owing to quenching technical postorder allowance is little, so the deflection in heat treatment of workpieces process to be controlled. Prior heat treatment frock is: directly use v block pave unsettled for workpiece or be directly positioned in flat board frock by workpiece level; although both traditional methods can both ensure the level of workpiece; but the deadweight due to the STRESS VARIATION in heat treatment process and workpiece; often occur that in heat treatment process, workpiece deformation is overproof, and due to technical problems such as the special not easily alignments of workpiece shapes.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of simple in construction and can control and adjust the adjustable pre-stressing heat treatment frock of heat treatment deformation amount, is especially suitable for stepped shaft-like workpiece.
For solving above-mentioned technical problem, the technical solution used in the present invention is: adjustable pre-stressing heat treatment frock, including: v block, guide post, screw rod and base; Below described screw rod and fixing with base respectively below guide post is connected, above screw rod with guide post above respectively with v block matched in clearance; Wherein, described guide post 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 the v block height at vertical direction by rotary motion;
Further, described screw rod top is provided with steel ball, and steel ball top contacts with v block;
Further, below described screw rod and be connected with whorl of base respectively below guide post;
Further, described guide post is by nut and base fastening.
The present invention has the advantage that and has the benefit effect that employing technical scheme of the present invention,
1, workpiece is in quenching heat treatment process, the distance of 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 the margin of tolerance is reserved between workpiece and v block, making workpiece STRESS VARIATION in quenching process will not be subject to frock to workpiece externally applied forces after expanding, the deformation also being able to avoid in without frock situation workpiece self gravitation simultaneously and causing is overproof.
Even if 2, large-scale shaft workpiece exist after quenching heat treatment process deformation overproof, it also is able to use the present invention when tempering to deformation ruler little progress Row sum-equal matrix: by overproof for shaft-like workpiece upper limit position upwards, v block is padded under axle, make workpiece unsettled, heating-up temperature when utilizing tempering and workpiece deadweight, namely be equivalent in a heated state the overproof position of the workpiece upper limit be applied external force, thus adjusting workpiece deformation size so that it is deformation amount controlling is in the margin of tolerance.
Additionally, the present invention also has the advantage such as simple in construction, easy to use, of many uses, long service life.

Detailed description of the invention
As Figure 1-Figure 2, the invention provides a kind of adjustable pre-stressing heat treatment frock, including: v block 2, guide post 3, screw rod 5 and base 7; Below described screw rod 5 and fixing with base 7 respectively below guide post 3 is connected, above screw rod 5 with guide post 3 above respectively with v block 2 matched in clearance; Wherein, described guide post 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 the v block 2 height at 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;
Below described screw rod 5 and threaded with base 7 respectively below guide post 3;
Described guide post 3 is fastened by nut 6 and base 7.
The work process of this example: operator's hand rotation screw rod 5, regulate the vertically distance of v block 2 to workpiece interval budget distance; Then adjustable pre-stressing heat treatment frock and workpiece 1 together shove charge are carried out Quenching Treatment; Measure the deflection of workpiece 1 after Quenching Treatment, adjust during tempering the vertically distance of v block 2 to workpiece interval budget distance, by adjustable pre-stressing heat treatment frock with workpiece with stove tempering.
Above one embodiment of the present of invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention. All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention.
