Abstract

The invention provides a gap detection device of a safety airbag, which comprises a base, three reference blocks, six simulation blocks, four dial indicators, four clamping devices and three positioning columns. Compared with the prior art, the gap detection device of the safety airbag has the advantages of high detection efficiency and simple operation. Only ten minutes are needed for detecting one airbag, therefore, the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a safety airbag gap detection device. Background technique [0002] In the process of producing airbags, the airbag gap value and surface difference dimension inspection shall be carried out according to the requirements of the test specifications. These size points all exist on the curved surface of the edge of the airbag, which cannot be detected with general-purpose measuring tools, and must be measured with contact three-coordinates. With the increase of output, the frequency of inspection is constantly increasing, which makes the task of three-coordinate measurement very heavy. In addition, using contact three-coordinates for measurement, the tolerance of the measurement point is large, the accuracy is not high, and the efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a safety airbag gap detection device in order to overcome the...
