Pressure and displacement testing mechanism for vehicle sunroof

Abstract

The invention relates to a pressure and displacement testing mechanism for a vehicle sunroof. The mechanism comprises a lower rack assembly and an upper rack assembly which are in butt joint, a vehicle body fixing frame positioning and adjusting device arranged on the lower rack assembly and used for fixing and position adjustment of a vehicle body fixing frame, a suction cup weight balancing device arranged on the upper rack assembly and used for absorbing the vehicle sunroof, and a displacement measuring device used for measuring the displacement amount of the vehicle sunroof. Pressure testing devices used for applying pressure to normal planes of different positions of the vehicle sunroof are arranged on the lower rack assembly and the upper rack assembly respectively. By means of the mechanism, adsorption of the vehicle sunroof and observation of the displacement amount of a certain part of the sunroof under specific gravity adsorption conditions can be achieved. Meanwhile, the displacement amount of the vehicle sunroof at a specific time under the condition of pressurizing and pressure maintaining can be realized in the rigid test; measuring data is accurate, rapid and convenient; the automation degree of the whole testing process is high; the testing efficiency of an enterprise is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile sunroof testing, in particular to a pressure displacement testing mechanism for the automobile sunroof. Background technique [0002] At present, in the field of sunroof sealing test, there is no mechanism for absorbing the sunroof of the car, and the adjustment of the angle of the sunroof is also blank. The sunroof is installed on different sizes of models, and at the same time, it can also realize the adsorption of the sunroof, as well as the test of the force and thrust in the adsorption action of the sunroof. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has made researches and improvements, and provides a pressure displacement testing mechanism for automobile sunroofs, which can not only satisfy the installation of different sizes of vehicles with sunroofs, but also realize the adsorption of the sunroofs. And the test of the force and thrust in...
