Abstract

The invention relates to a testing device. The testing device is used for detecting the local rigidity and anti-sag ability of the white car body of a car. The testing device comprises a measuring unit, the measuring unit is connected with a posture adjustment mechanism, the posture adjustment mechanism comprises a first rotary seat and a second rotary seat, a first rotation drive mechanism is arranged on a stand, the first rotation drive mechanism is connected with the first rotary seat and drives the first rotary seat to rotate, the first rotary seat is provided with a second rotation drive mechanism, and the second rotation drive mechanism is connected with the second rotary seat and drives the second rotary seat to rotate. The measuring unit located on the rotary seat can be adjusted flexibly so as to enable the measuring end on the measuring unit to apply load to the plate surface of the car body to be tested, and load and displacement value measured by the measuring unit are fed back to a computer to analyze so as to obtain the local static rigidity and anti-sag ability of the white car body; the testing device is flexible, high in automation level and high in measuring precision.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and in particular relates to a test device for detecting local stiffness and anti-sag ability of an automobile body in white. Background technique [0002] In the process of R&D and debugging of automobiles, it is necessary to test the local stiffness and anti-sag ability of the body-in-white surface to meet the performance requirements after actual mass production and application, such as testing door hinge fixing points, engine hood hinge fixing points, and luggage compartments. The static stiffness of the key points of the body such as the fixed point of the lid hinge, the fixed point of the door lock pin, the fixed point of the shift mechanism, the fixed point of the sunroof, and the anti-sag ability of the sheet metal parts on the outer surface of the body. The test device in the prior art has a low degree of automation, low detection efficiency, and inflexible detection equipment. Wh...
