Problems solved by technology
[0008] 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 for a safety belt retractor. Linear sliding rails (503) are arranged on a rotary working table plate (2), sliding blocks (510) are arranged on the linear sliding rails (503), a sliding table (502) is arranged on the sliding blocks (510), and a rotary table (501) for fixing the safety belt retractor is fixed on the sliding table (502) through limit bolts; and synchronous belt clamping plates (511) for clamping an adjustor synchronous belt (509) are fixed on the inner side of the sliding table (502). By means of the technical scheme, the durability test of the safety belt retractor is standardized, the test method controllability is improved, the tester labor intensity is reduced, test data authenticity is improved greatly, and durability data of the safety belt retractor can be provided for design departments rapidly and accurately; the product quality stabilization is facilitated, and a great role is played in novel product development, novel material usage and the whole vehicle performance improvement.
Description
[0001] This application is a divisional application of the following original application: [0002] Date of original filing: September 24, 2011 [0003] Original application number: 2011102872472 [0004] Original name: Seat belt retractor durability test equipment technical field [0005] 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 [0006] 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 carr...
