Description
Technical Field
The utility model relates to a tool for an accelerated aging test of a sealing ring, in particular to a compression deformer for accelerated aging of a sealing ring of a solid rocket engine.
Background
The sealing ring of the solid rocket engine is a rubber part, and is aged under the influence of temperature in the long-term use process, so that the performance is reduced, and the service life of the sealing ring is greatly estimated through an accelerated aging test. The sealing ring of the solid rocket engine is closed in use environment and has a certain compression amount, so that how to better simulate the use environment is particularly important for the accelerated aging test of the sealing ring of the solid rocket engine.
The existing device comprises compression plates and limiting blocks, wherein a sealing ring and the limiting blocks are placed between the two compression plates during testing, a through hole is formed in the center of each compression plate, a bolt penetrates through the through hole and is screwed down, and the compression amount of the sealing ring is guaranteed through the limiting blocks.
The sealing ring passes through an accelerated aging test, which is an important link for estimating the service life of the sealing ring, and the original technical scheme cannot simulate a real test environment, so that the sealing ring is exposed to a high-temperature environment during the test, and the test result is influenced; and original technical scheme gets the compression plate and compresses tightly through the bolt in the middle of the compression plate, and device processing requires highly, makes the sealing washer can not by even compression, influences the test result.
Disclosure of Invention
Technical problem to be solved by the utility model

Detailed Description
The utility model provides a compression deformer for accelerated aging of a sealing ring of a solid rocket engine, which comprises a bottom plate and a pressing plate. The pressing plate is pressed on the bottom plate in a plane manner, and the sealing ring is compressed to a specified compression amount to be positioned in a closed space; one side of the bottom plate is provided with a groove for placing a sealing ring, the depth of the groove is determined according to the compression amount of the sealing ring, the other side of the bottom plate is a plane, and when a plurality of bottom plates are used together, the plane part of the bottom plate can be used as a pressing plate to be pressed on the other bottom plate; through holes with the same size are uniformly distributed on the outer sides of the bottom plate and the pressing plate, the number of the through holes is determined according to the size of the compression deformer, and the bottom plate and the pressing plate are tightly connected through bolts. The pressing plate is pressed on the bottom plate to form a closed environment, so that the real use environment is well simulated.
In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is obvious that the described embodiments are only some, not all embodiments of the proposed solution. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figure 1, the plane view of a base plate of a compression deformer for accelerating the aging of a sealing ring of a solid rocket engine is provided with a slot 1 and a through hole 2. The bottom plate is used for placing the sealing washer, and the position of placing is fluting 1, and the groove depth of fluting 1 decides according to the compressive capacity of sealing washer. The through-hole 2 is for fastening by a bolt.
As shown in fig. 2, the compression deformer pressing plate for accelerated aging of the sealing ring of the solid rocket engine is a plan view, and comprises a pressing plate and a through hole 2. The pressing plate is the same as the bottom plate in size and is used for pressing the bottom plate and compressing the sealing ring to a specified compression amount, so that the sealing ring is in a closed space. The through hole 2 of the pressing plate has the same size as the through hole 2 of the base plate for fastening by a bolt.
During specific implementation, the sealing rings are placed at the grooves of the base plates, a plurality of base plates can be placed in sequence, the pressing plates are placed on the base plates, the through holes of each base plate and each pressing plate are aligned, the base plates penetrate through the bolts to be fastened and apply torque, the compression uniformity of the sealing rings is guaranteed, and the test precision is improved.
When the sealing ring test device is used, a plurality of bottom plates can be placed at the same time, so that a plurality of sealing rings can be tested at the same time, the test efficiency is improved, and the processing number of the device is reduced.
