Abstract

The invention discloses a rapid clamping device for trolley collision test. The rapid clamping device comprises a trolley table board; a sample fixing plate, which is movably arranged on the trolley table board; a first shaft coupling clamp assembly, which is arranged on one end of the trolley table board and is used for fixing one end of the sample fixing plate on the trolley table board; and a second shaft coupling clamp assembly, which is arranged at the other end of the trolley table board and can fix the other end of the sample fixing plate to the trolley table board, wherein each shaft coupling clamp assembly comprises at least two clamp bodies, a linkage device arranged between the clamp bodies, and a hydraulic device which is arranged at one end of the linkage device, and can drivethe linkage device to synchronously drive the clamp bodies to fix the sample fixing plate. According to the designed rapid clamping device for the trolley collision test, the multiple clamp bodies are arranged at the two ends of the sample fixing plate correspondingly, the clamps are synchronously driven by the linkage device to fix the sample fixing plate, and assembly and calibration are not needed, so that fixing time is saved.

Description

technical field [0001] The invention relates to the field of automobile collision test equipment, in particular to a quick clamping device for a trolley collision test. Background technique [0002] In the traditional trolley crash test, the test sample is welded to the frame and connected to the bottom plate, and multiple bolts are used to fix the sample on the platform of the test trolley for the test. At the test site, a large number of screws need to be manually tightened to fix the test sample on the trolley. After the test, the screws need to be loosened one by one. The test preparation process takes a long time, the operation is cumbersome, and more labor is required. [0003] Especially with the rapid development of electric vehicles at present, the safety of electric vehicles is highly valued. Whether it is from enterprise research and development to standard requirements, it is necessary to carry out a large number of crash tests on electric vehicles, battery pack ...
