Abstract

The invention provides a micro-scale biaxial and bidirectional loading testing machine. The machine includes a rack platform assembly, a stretching mechanism assembly, a load measuring assembly, a fixture assembly, and a strain measurement assembly. The stretching mechanism assembly is mounted on the rack platform assembly through bolts. The stretching mechanism assembly and the load measuring assembly are threadingly fixed. A grating scale and a linear guide rail of the load measuring assembly are fixed to the rack platform assembly through bolts. The load measuring assembly and the fixture assembly are connected to each other through pins. The strain measurement assembly is fixed to the rack platform assembly through bolt. According to the invention, fixtures of different sizes and sensors of different measuring ranges are selected according to different test loads. The device is convenient in mounting and dismounting, can realize non-contact strain measurement and experimental loadmeasurement, is simple in structure and good in manufacturability, and has popularization and application value.

Description

technical field [0001] The invention designs a micro-scale biaxial bidirectional loading testing machine, which can be used to test materials, especially for the mechanical properties of thin plates with a thickness of 0.02-0.4mm under the tension state of double bearings, which belongs to engineering materials and physical properties. , Mechanical experiment technology field. Background technique [0002] In recent years, with the increasingly prominent problems of environmental pollution and energy shortage, the market demand for micro-products has increased significantly, and more and more micro-formed parts are used in microelectronics, automobiles, aviation and medical fields. Microforming inherits the advantages of traditional plastic processing technology, but when the size of the material is reduced to a certain extent, its industrial application is limited due to many problems such as scale effect, increased frictional resistance, and difficulty in precise positioni...
