Abstract

A pull-out force detection device provided by the present invention is used to detect a pull-out force between a bolt and a sleeve, and the sleeve is equipped with a gap penetrating the two ends of the sleeve along an axial direction of the sleeve. The pull-out force detection device comprises a pedestal and a pull block, the pedestal comprises a first fixing plate and a second fixing plate, and the bolt is fixed to the pedestal via the first and second fixing plates. The first and second fixing plates stops the bolt to move along the radial direction of the bolt, the sleeve sleeves the bolt and is located between the first and second fixing plates, and the pull block is fixed at one side far away from the pedestal of the side wall of the sleeve. The pull-out force detection device provided by the present invention can simulate the stress status between the bolt and the sleeve in a subframe fall-off structure, and can measure the pull-out force between the bolt and the sleeve more accurately.

Description

technical field [0001] The invention relates to the field of auto parts detection, in particular to a pull-off force detection device. Background technique [0002] With the development of technology, people have higher and higher requirements for the safety performance of automobiles. Most of the engines of existing automobiles are located at the front of the vehicle. Generally, when the automobile has a frontal collision, the body structure will collapse and deform. , to absorb the energy generated during the collision. [0003] In the prior art, in order to ensure a good front view and passability, the length of the vehicle's front overhang tends to be shortened. The front overhang is shortened, but the arrangement of the human body remains unchanged relative to the center of the front wheel, which will inevitably lead to the front end of the vehicle being sucked. The energy space is shortened, so that the collision energy cannot be effectively absorbed by the front-end ...
