Abstract

The invention discloses an automatic circulation impact fatigue test device. The test device comprising a base, a clamping assembly, supporting plates vertically arranged on the base and located on the two sides of the clamping assembly, guide rods vertically arranged on the base and parallel to the supporting plates, lifting driving assemblies arranged at top ends of the supporting plates and used for driving the clamping assembly to ascend and descend along the supporting plates, an opening and closing assembly which is arranged on the guide rod in a sleeving mode and used for controlling opening and closing of the clamping assembly, and an impact assembly which is arranged on the guide rod in a sleeving mode and clamped by the clamping assembly, wherein the opening and closing assembly is located above the impact assembly, the impact assembly is slidably connected with the guide rod, and the clamping assembly is located between the opening and closing assembly and the impact assembly; a test placement assembly is arranged on the base, and the test placement assembly corresponds to the impact assembly. By arranging the lifting driving assembly, the clamping assembly, the opening and closing assembly, the impact assembly and the test placement assembly, circulation efficiency of the impact fatigue test device is improved, and meanwhile, accuracy of experimental data is improved.

Description

technical field [0001] The invention relates to the technical field of impact fatigue test equipment, in particular to an automatic cycle impact fatigue test device. Background technique [0002] Impact fatigue refers to the failure phenomena of crack initiation, accumulation, and even material peeling or fracture on the surface of parts under fixed or unfixed cyclic impact loads. It is also one of the common forms of fatigue in life. In particular, the vibration generated during the operation of the equipment or brought about by the environmental conditions is the key factor causing the rigid impact between the components, which has brought a lot of unnecessary economic losses to the industrial production activities of the society. [0003] In mechanical equipment, the parts and components on the equipment are often subject to cyclic shocks. For example, the vibration of the equipment itself during operation will cause cyclic shocks to the parts, or the interference of the ...
