Description

G-shaped frame type tool

Technical Field

The utility model relates to an indentation analysis appearance frock technical field specifically relates to a G type frame frock.

Background

The G-like frame is common in the field of table hardometers, is a tool matched with a real-time indentation analyzer and applied to mechanical property detection of laboratory materials, wherein most of the G-like frames are provided with a hole or a groove at the top end of the table frame for placing a vertical loading device of the hardometer, and the lifting mode of the objective table is also different. However, the existing tool used for the laboratory test scene is of an integrated structure in the test, the volume is large, and a main machine and a fixed support of the test are not detachable, such as a laboratory model AIT-U (tensile property and Vickers hardness are nondestructively tested in a laboratory), a Micro AIS (tensile property, Vickers hardness, residual stress and quantitative analysis for detecting a Micro test piece and a coating), a Nano AIS (tensile property, Vickers hardness and residual stress for detecting a Micro area test piece) and the like. This makes it difficult to disassemble the gauge head from the G-type jig fixture, resulting in limited detectable specimen size, and making the fixture difficult to mate with a subsequently upgraded host.

For a high-precision instrument, if the rigidity of the frame is insufficient, microscopic deformation is generated under the action of tension, the influence on the measurement of the sample indentation depth can be influenced, and the influence on the final test result is huge. When the pressure head applies the same load to the sample and the load is larger, the frame with the long force arm needs to be thickened to eliminate the micro deformation of the frame under the action of tension. For most of shelves of hardmeters on the market, the bending angle is larger to form a semi-enclosed structure, the moment arm is long and large, and the tension of the shelf due to the long moment arm is larger. This causes the thick heavier material of current frock frame, leads to the cost to rise, and has increased the degree of difficulty of transport use.
