Abstract

The invention discloses a double-shaft lifting lug fatigue performance testing device, aims to provide a testing device capable of effectively detecting the fatigue performance of a lifting lug, and is characterized in that the double-shaft lifting lug fatigue performance testing device comprises a base, and a detection device is arranged on the base, the detection device comprises a sliding device arranged on the base, a pushing device connected with the sliding device, a fixing tool arranged on one side far away from the pushing device, a first lifting hook arranged on the fixing tool, a second lifting hook arranged on the pushing device, a lifting lug which is positioned between the first lifting hook and the second lifting hook, and a data analyzer which is electrically connected with the pushing device.

Description

technical field [0001] The invention relates to the field of component detection devices, in particular to a biaxial lifting lug fatigue performance testing device. Background technique [0002] The lifting lug is a key component connecting the cold end of the complete exhaust system with the body. How to ensure its fatigue durability under the complex working conditions of the automobile has been an important issue that the industry has been concerned about. At present, the major lifting lug manufacturing enterprises , most of them only pay attention to the Z-direction fatigue performance of the lifting lug. In the fatigue test, only the fatigue load on the lifting lug in the vertical direction is considered. The directions will still be subjected to non-negligible loads. How to carry out multi-directional fatigue test loading on the lifting lug at the same time is a difficult problem in fatigue testing in the industry. [0003] At present, the Chinese patent with the publ...
