Description

A high-temperature tensile testing fixture with cooling function Technical Field

[0001] This utility model relates to the field of fixture equipment, specifically a high-temperature tensile test fixture with cooling function. Background Technology

[0002] With the continuous development of aero engines, especially new detonation engines, the performance requirements for various new engines are becoming increasingly stringent. The temperatures of the combustion chambers and nozzles of these new engines are rising, placing higher demands on the high-temperature performance, particularly the ablation resistance, of materials. To further improve the high-temperature resistance of these materials, high-temperature performance tests are becoming increasingly common. Existing high-temperature tensile testing fixtures cannot effectively cool the fixture itself, leading to continuous heat transfer to the testing equipment connected to the fixture, which affects the equipment's lifespan. Therefore, to meet the demands of high-temperature testing of high-temperature materials, there is an urgent need to design tensile testing fixtures that meet high-temperature requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a high-temperature tensile test fixture with a cooling function to solve the above problems. It has a self-cooling function and can effectively clamp the test piece for high-temperature testing. The fixture has a simple structure, is easy to assemble, and has great promotion and application value.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a high-temperature tensile test fixture with cooling function, comprising a first clamping plate, a second clamping plate, and a test piece. The first clamping plate and the second clamping plate are respectively disposed on both sides of the end of the test piece. The bottoms of the first clamping plate and the second clamping plate are respectively connected and fixed by mounting bases, and the tops are connected and fixed by a fixing structure. The first clamping plate and the second clamping plate are respectively provided with a first cooling channel and a second cooling channel that are interconnected.

[0005] Furthermore, a connecting column is installed at the bottom of the mounting base, and fixing plates are provided on the left and right sides above the mounting base.

[0006] Furthermore, the connecting post has threads on its outer periphery.

[0007] Furthermore, both the bottom outer sides of the first clamping plate and the second clamping plate are provided with fixing slots for the fixing insert plate to be inserted, and the first clamping plate and the second clamping plate are respectively fixedly connected to the fixing insert plate by insert plate screws.

[0008] Furthermore, at least one of the first clamping plate and the second clamping plate has a limiting groove on its inner side that is adapted to the end of the test piece.

[0009] Furthermore, one end of the test piece is provided with a wedge-shaped head, and the limiting groove is a wedge-shaped groove adapted to the wedge-shaped head.

[0010] Furthermore, the fixing structure includes at least one fixing bolt, which passes through the first clamping plate and the second clamping plate in sequence and is fixedly connected to the fixing threaded plate.

[0011] Furthermore, the outer side of the second clamping plate is provided with a positioning groove for accommodating the fixing threaded piece. The depth of the positioning groove is not less than the thickness of the fixing threaded piece, which allows the fixing threaded piece to be lower than the outer side of the clamp, thus preventing it from colliding with other objects and falling off.

[0012] Furthermore, the outer side of the first clamping plate is provided with a receiving groove to accommodate the end of the fixing bolt.

[0013] Furthermore, one end of the first cooling channel is connected to the liquid inlet pipe, the other end of the first cooling channel is connected to one end of the adapter pipe, the other end of the adapter pipe is connected to one end of the second cooling channel, and the other end of the second cooling channel is connected to the liquid outlet pipe.

The first clamping plate 1 and the second clamping plate 2 are respectively disposed on both sides of the end of the test piece 4. The bottoms of the first clamping plate 1 and the second clamping plate 2 are respectively connected and fixed by a mounting base 3, and the tops are connected and fixed by a fixing structure. The first clamping plate 1 and the second clamping plate 2 are respectively provided with a first cooling channel 103 and a second cooling channel 201 that are interconnected. A connecting post 301 is installed at the bottom of the mounting base 3, and fixing inserts 302 are provided on the left and right sides above the mounting base 3. The connecting post 301 has threads on its outer periphery, which can be used for threaded connection with external hydraulic equipment. The bottom outer sides of the first clamping plate 1 and the second clamping plate 2 are provided with fixing slots for the fixing inserts 302 to be inserted, and the first clamping plate 1 and the second clamping plate 2 are respectively connected to the fixing inserts 3 by insert screws 10. 02 Fixed connection; at least one of the first clamping plate 1 and the second clamping plate 2 has a limiting groove 101 on its inner side that is adapted to the end of the test piece 4; at least one end of the test piece 4 has a wedge head 401, and the limiting groove 101 is a wedge groove adapted to the wedge head 401; the fixed structure includes at least one fixing bolt 5, which passes through the first clamping plate 1 and the second clamping plate 2 in sequence and is fixedly connected to the fixing threaded piece 6; the outer side of the second clamping plate 2 has a positioning groove for accommodating the fixing threaded piece 6, and the depth of the positioning groove is not less than the thickness of the fixing threaded piece 6; the outer side of the first clamping plate 1 has a receiving groove 102 for accommodating the end of the fixing bolt 5; one end of the first cooling channel 103 is connected to the liquid inlet pipe 9, the other end of the first cooling channel 103 is connected to one end of the adapter pipe 7, the other end of the adapter pipe 7 is connected to one end of the second cooling channel 201, and the other end of the second cooling channel 201 is connected to the liquid outlet pipe 8.

[0023] In practical use, the test piece 4 is first inserted into the limiting groove 101 of the first clamping plate 1, and then the second clamping plate 2 is placed on top. An mounting base 3 is installed below the first clamping plate 1 and the second clamping plate 2. Fixing inserts 302 are inserted into the fixing slots of the first clamping plate 1 and the second clamping plate 2. Each of the first clamping plate 1 and the second clamping plate 2 has an insert screw 10 on its outer side. The insert screw 10 passes through the fixing inserts 302 on both sides and is threaded to the first clamping plate 1 and the second clamping plate 2, thus fixing the bottom of the first clamping plate 1 and the second clamping plate 2. Then, fixing bolts 5 are passed through the first clamping plate 1 and the second clamping plate 2 and threaded to the fixing threaded plate 6.
