Problems solved by technology
[0004] However, the retractor adjustment device in the durability test equipment of the seat belt retractor uses a manual control screw to simulate the acceleration of the seat belt retractor itself, and the labor intensity of the test personnel is relatively large, so it is impossible to The acceleration value of the seat belt retractor itself is controlled, and the controllability is poor, which is not conducive to the collection and analysis of test data, which reduces the accuracy and integrity of the test data to a certain extent

The invention discloses a durability test device of a seat belt retractor, wherein a retractor regulator (5) is arranged on a rotary working table plate (2) through a slide rail and slide block mechanism, a slide block in the slide rail and slide block mechanism moves on a slide rail under the drive of a regulator servo motor (505) and a regulator belt transmission mechanism (504) which are arranged on the rotary working table plate (2). By adopting the technical scheme, the durability test of the seat belt retractor is specified, the control property of a test method is improved, the labor intensity of testers is reduced, the authenticity of test data is greatly increased, and the durability property data of the seat belt retractor can be rapidly and accurately provided for a design department. The durability test device is beneficial to stabilization of product quality, and plays a larger role in developing new products, utilizing new materials and improving integral property.
Description
technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to the technology of automobile safety device test equipment. Specifically, the present invention relates to a durability test device for a seat belt retractor. Background technique [0002] Car seat belts are usually made of high-strength synthetic fibers and have automatic retractors. The seat belt retractor is a very important part of the seat belt safety restraint system. Its performance directly determines whether the seat belt can protect the driver and passengers in the event of an accident. Therefore, in the design and manufacture process of the seat belt retractor, it is indispensable to carry out the durability test. [0003] In the prior art, the Chinese utility model patent (authorized announcement number CN201233324Y) named "Retractor Durability Test Equipment" discloses a test equipment for testing the durability of seat belt retractors, according to t...
