Problems solved by technology

This is not only cumbersome to use, but also because the lower pressing plate (104) is not fixed, its bearing capacity is small, and it is easy to move, resulting in inaccurate test results, and it is not possible to test large-weight test pieces

Abstract

The invention relates to a multifunctional compression and shear test machine. The test machine adopts the structure that a vertical column is arranged on a machine frame; a main oil cylinder is fixed at the top of the vertical column; a main piston rod is matched with and driven by the main oil cylinder; an upper compression plate is fixed at the bottom of the main piston rod; guide rails are arranged on the left side and the right side of the machine frame respectively; a dynamic compression plate and a shear mechanism are arranged on the guide rails respectively; a corner oil cylinder is mounted on one side of the machine frame; a lower bearing plate is fixed onto the machine frame; rolling shaft roller sets are arranged on the lower bearing plate; a cushion plate is supported on the rolling shaft roller sets; a pressure sensor is arranged in the cushion plate; dynamic supporting frames are fixed on the front and rear sides of the machine frame; a dynamic hydraulic oil cylinder is mounted on one dynamic supporting frame; one end of a dynamic hydraulic piston rod is connected with the dynamic hydraulic oil cylinder; the other end of the dynamic hydraulic piston rod can be connected with and can drive the dynamic compression plate; a dynamic sensor is arranged on the dynamic hydraulic piston rod. The compression shear test machine can be used for testing static pressure, dynamic pressure, shear force and corner performance, and has the advantages of functional diversity, high bearing capacity, convenience in use and the like .

Description

technical field [0001] The invention relates to mechanical testing equipment, in particular to a multifunctional compression-shear testing machine, which belongs to the technical field of testing equipment. Background technique [0002] The compression-shear testing machine of the prior art is shown in the invention No. 200620042299.8 of the People's Republic of China, which drives the beam (105) and the upper platen (103) to move downward along the column (102) through the drive motor (106) during the pressure test ; At the same time, push the lower platen (104) through the vertical oil cylinder (111) and the vertical piston (112), so that the upper platen (103) and the lower platen (104) are abutted to carry out the static pressure test. Therefore, the above-mentioned compression-shear testing machine cannot The test is performed against dynamic pressure, which creates certain application limitations. [0003] When the above-mentioned compression-shear testing machine per...
