Abstract
The utility model discloses a kind of blast shield jig; including protection cap and rubber ring; rubber ring holding tank is provided with the protection cap; rubber ring is arranged in rubber ring holding tank; and the cylindrical tight fit of the inwall of rubber ring holding tank and rubber ring; the rubber ring middle part is additionally provided with protection hole, and shape and the outer shape of part in the protection hole match.Using blast shield jig described in the utility model, it is ensured that part will not cause blast shield jig to be blown off in blast because blast is excessive, so that beyond desired blast scope.The blast that the blast fixture is applied to various like parts is protected, easy to operate, safe, with preferable economic benefit and social benefit.
Description
Technical field
The utility model belongs to piece surface protection technology field, and in particular to a kind of blast shield jig.
Background technology
Aero-engine component requires to carry out its entirety blast after heat treatment, but requires on component
Single-piece is protected, and blast is not allowed in the range of its φ 150mm.To meet protection requirement during above-mentioned blast to part, mesh
Before be typically with rubber ring part protected；Existing blast shield jig is typically centrally disposed one in rubber ring
Then circular hole, iron covering is buckled during blast by the rubber ring sleeve with circular hole on the part that need to be protected.The deficiency of the fixture be due to
The circle at rubber ring center is different with the part shape that need to be protected, and fixture is buckled in when on part, and space can be left around part, button
It is not tight, when blast, because blast is excessive, may result in rubber ring and blown off, so that beyond desired blast scope.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of blast shield jig；To ensure part in blast
When effect.
The utility model is achieved by the following technical programs.
A kind of blast shield jig, including protection cap and rubber ring, are provided with rubber ring holding tank, rubber in the protection cap
Cushion rubber is arranged in rubber ring holding tank, and inwall and the rubber ring of rubber ring holding tank cylindrical tight fit, the rubber
Circle middle part is additionally provided with protection hole.
Further, the shape in the protection hole matches with the outer shape of part.
Further, it is the versatility of raising shield jig, the protection hole is ellipsoid like structure.
Further, the protection cap is provided centrally with through hole, and through hole is concentric with protection hole.
Further, the upper plane of the protection cap and the upper plane of rubber ring are concordant.
The beneficial effects of the utility model are：
Using blast shield jig described in the utility model, it is ensured that part will not be because blast be excessive in blast
Blast shield jig is caused to be blown off, so that beyond desired blast scope.The blast fixture is applied to various like parts
Blast is protected, easy to operate, safe, with preferable economic benefit and social benefit.

Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in Figures 1 to 5, a kind of blast shield jig described in the utility model, including protection cap 1 and rubber ring 2,
Rubber ring holding tank 101 is provided with the protection cap 1, rubber ring 2 is arranged in rubber ring holding tank 101, and rubber ring holds
Receive the inwall of groove 101 and the cylindrical tight fit of rubber ring 2, the middle part of the rubber ring 2 is additionally provided with protection hole 201.Using this
Technical scheme, when blast is carried out, the protection hole 201 on rubber ring 2 is sleeved on the part that need to be protected, then by protection cap
1 is enclosed within the outside of rubber ring 2, and makes rubber ring holding tank 101 and the good seal of rubber ring 2, so as to effectively be protected to part.
The shape in the protection hole 201 matches with the outer shape of part.So, when rubber ring 2 is enclosed within part,
Part is tightly fitted with rubber ring 2, around without any space, therefore in blast, will not be blown rubber ring 2 because blast is excessive
Fall, without departing from desired blast scope, greatly improve blast protecting effect.
The protection hole 201 is ellipsoid like structure.The versatility of shield jig can so be improved so that protection hole
201 can protect to part of different shapes.
The protection cap 1 is provided centrally with through hole 102, and through hole 102 is concentric with protection hole 201.
The upper plane of the protection cap 1 is concordant with the upper plane of rubber ring 2.Can so make protection cap 1 and rubber ring 2 common
Part is formed with sealing is protected, be further ensured that blast effect.
