Description

Damping shrinkage time adjusting jig Technical Field The utility model belongs to the field of automobile accessory test adjustment, and particularly relates to a damping shrinkage time adjustment jig for a sun visor roller shutter. Background In the automobile manufacturing industry, the sun shield roller blind is used as an important accessory in a vehicle, can effectively shield sunlight, provides a comfortable riding environment for drivers and passengers, and can protect interior decoration of the vehicle from ultraviolet rays to a certain extent. However, in the process of producing and assembling the sun visor roller blind, the step of damping adjustment often becomes a difficult problem for limiting production efficiency and product quality. The traditional damping adjustment means often depend on personal experience and hand feeling of operators, which means that each worker can operate by adopting different standards and methods, uncertainty and variable in the production process are increased, and the damping effect close to ideal can be achieved by repeated manual adjustment, so that the manual mode is time-consuming and labor-consuming, and production cost is increased. In particular, conventional damping adjustment methods often lack quantitative standards and accurate measurement means, resulting in the possibility of large fluctuations in the shrinkage speed of the roller blind in actual use. Too fast or too slow shrink has not only influenced the use convenience and the user experience of sunshading board roller shutter, still probably aggravate the wearing and tearing of part because of frequent mechanical movement, shortens the life of product. More importantly, the mode of relying on repeated trial and error and manual adjustment cannot ensure the consistency and accuracy of each adjustment, so that the sun-shading board roller blinds in different batches and even in the same batch can have obvious difference in damping performance, and the overall quality and market competitiveness of the product are seriously affected. Therefore, how to design a fixture capable of efficiently and accurately adjusting the damping shrinkage time of the roller shutter of the sun shield becomes a problem to be solved in the automobile manufacturing industry.
