Description

Technical Field

[0001] The utility model relates to the technical field of engineering material testing, in particular to a testing machine for engineering material testing. Background Art

[0002] Engineering materials are materials used in engineering fields such as machinery, vehicles, ships, construction, chemical industry, energy, instrumentation, aerospace, etc. They are used to manufacture engineering components and mechanical parts. They also include some materials used to manufacture tools and materials with special properties. Engineering materials are generally divided into four categories according to their chemical composition: metal materials, non-metallic materials, polymer materials and composite materials. Before the application of engineering materials, they need to be tested by testing machines such as tension and compression. In actual use, they have the advantages of simple operation, safe use and accurate testing.

[0003] The prior art discloses a MTS material testing machine for municipal engineering quality inspection with a publication number of CN217277385U, which includes a test bench, a supporting base plate, a supporting column, a supporting crossbeam, a fixing frame, a protective door, an observation port, a control panel, a pneumatic component, a moving block, a first tensile clamp, a second tensile clamp, a first compression clamp, a second compression clamp, a clamping plate, a slide, a fixing seat and a fixing pin. When in use, the material is directly placed on the second tensile clamp, and the clamping plate is driven by the pneumatic component to clamp it. At the same time, when clamping different materials, the fixing pin on the fixing seat can be removed, and then it can be taken out. It can be replaced by replacing the appropriate fixture for operation, which is convenient for operation on different materials. It solves the problem that the video recorded by the review camera can be used in the prior art to help the inspector analyze the fracture or stretching process of the material, but it is inconvenient to clamp when testing different materials, thus affecting the use effect. A fixed frame is provided on the front end face of the supporting column, and a protective door is installed on the fixed frame. The protective door can be used for protection during operation to avoid unexpected situations during operation and splashing of the tested material. At the same time, an observation port is provided on the protective door for convenient observation during operation.

[0004] The above utility model can only perform tensile or compression tests on one engineering material at a time. When multiple engineering materials need to be tested, the operator needs to frequently change the engineering materials for testing. Replacing the engineering materials will increase the time consumption and reduce the test efficiency of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
