Securing band dust test multi-angle Intelligent test bed
Technical field
The present invention relates to safety belt test technical field of mechanical equipment, particularly relating to a kind of multi-angle Intelligent test bed for detecting car belt dust test.
Background technology
Securing band is as the mandatory inspection product of a current state motor vehicle product, and the dust test of its coiler is an important performance test link.Requirement regulation according to the clause 5.6.3 " dust test " in National Standard of the People's Republic of China GB14166-2013 " safety belt for motor vehicle passenger, constrained system, child restrainnt system and ISOFIX child restrainnt system ": coiler should be arranged in dust test case, and its mounting means is similar to the installment state on vehicle.The dust of regulation is equipped with in chamber, carries out, outside No. 10 securing band pull-out backrush tests, keeping ribbon to be in and pull out 500mm length condition from coiler after each stirring dust in 1min ~ 2min.In 5h, every 20min, with gauge pressure for 5.5 × 105 ± 0.5 × 105Pa, and the dried compressed air of not oil-containing, the aperture being 1.5mm ± 0.1mm by a diameter blows flour stirring dirt 5 seconds.
Generally common securing band dust test equipment should comprise securing band fixed mechanism, guiding mechanism, actuating unit and control system etc.Securing band fixed mechanism is generally directly be fixed on benchmark table top by bolt or welding, arm need be stretched in narrow space and carry out clamping when installing securing band, operation and inconvenience thereof.Fixed mechanism material use cast iron process part is fixed, and can only carry out clamping to the securing band of vertical pull-out, then cannot clamping to the coiler at level pull-out or band angle of inclination, causes test to carry out; Guiding mechanism utilizes mechanical rigid connection, the ribbon parts of safety belt test sample is easily caused to the uncertainty damage causing affecting test findings; Actuating unit adopts common cylinder, and long-term dust work use can cause cylinder to use the serious life-span to decline.Control system, usually use button and pilot lamp, displaying contents only has test period usually, shows without any test figure.Program part then major part uses mcu programming, and contents of program is single fixing, and testing crew cannot change setting, can not meet producer's research and development demand.
