Rotation durability testing device for whip-shaped lock

Abstract

The invention discloses a rotation durability testing device for a whip-shaped lock. The device comprises a working platform (1), a welding crow foot (2) and a swinging platform (11), wherein the welding crow foot (2) is fixed on the working platform (1); a lock catch clamp assembly (3007) for fixing a whip-shaped lock catch is fixed on the welding crow foot (2); the swinging platform (11) which is fixed on the working platform (1); and a rotation clamp assembly (8010) is fixed on the swinging platform (11). In the rotation durability testing device with a special structure for the whip-shaped lock, appropriate clamps are selected for measuring whip-shaped locks of different models, so that the problem of insufficient clamping force of a clamp on a whip-shaped lock can be effectively solved, and the phenomenon of swinging generated in the testing process of the whip-shaped lock is avoided; and the swinging frequency of the selected swinging platform is 30 times per minute, and the rotating angle is + / -80 degrees, so that the requirements of most testing can be met, and the accuracy and completeness of testing data are greatly increased.

Description

technical field [0001] The invention relates to a rotation durability test device, in particular to a test device for testing the rotation durability of a whip lock. Background technique [0002] The seat belt whip lock, as a part of the seat belt, also plays a very important auxiliary safety protection role in the driver's driving process. There are mandatory regulations at home and abroad, because its quality directly affects the life safety of drivers and passengers, so its various properties must be tested before loading, such as service life. Therefore, in the test process, a special test device for rotation durability of the seat belt whip lock is needed. [0003] At present, the type of fixture used for the rotation durability test device is single, which cannot meet the rotation durability test of different types of whip locks—the clamping force for the whip lock during the test is not enough, which may cause the whip lock to swing, or even The shedding occurs, whi...

Problems solved by technology

[0003] At present, the type of fixture used for the rotation durability test device is single, which cannot meet the rotation durability test of different types of whip locks—the clamping force for the whip lock during the test is not enough, which may cause the whip lock to swing, or even The shedding occurred, which affected the accuracy of the test data; the angle range that can be measured is also small, and the durability of rotation at a large angle cannot be tested, which greatly reduces the integrity of the test data and ultimately affects the safe use performance of the seat belt
