Intelligent automobile maintenance pretreatment system

Abstract

The invention relates to an intelligent automobile maintenance pretreatment system. The system is characterized in that before a sunken area is repaired, an optimal stretching angle is determined through a sunken surface contour coordinate set f(x, y, z) of a sunken position of a central control processor; when the sunken area is repaired, the central control processor determines the tensile strength and the heating temperature of an absorber according to the yield strength of the position where the sunken position is located, controls the absorber on the mechanical arm to conduct stretching, divides stretching stages, corrects the stretching direction every time the stretching stage is passed and determines an optimal stretching angle to avoid secondary deformation of the sunken position due to the improper stretching angle, meanwhile, the stretching direction is corrected according to each stretching stage, the influence caused by accidental deformation in the stretching process is eliminated, the stretching direction is adjusted in real time, and the final deformation recovery effect is ensured.

Description

technical field [0001] The invention belongs to the field of automobile maintenance, in particular to an intelligent automobile maintenance pretreatment system. Background technique [0002] Due to the gradual increase in people's demand for automobiles, automobile-related industries such as automobile manufacturing, automobile sales, automobile inspection and maintenance have also flourished. It is becoming more and more prosperous. Among them, the deformation of the car shell, the accident of collision and depression is particularly reflected. Usually, the depression position of the shell can be recovered to a certain deformation through suction by the suction cup. However, in the prior art, there are still the following problems; [0003] 1. In the prior art, when aiming at the concave position with large deformation, there is a lack of three-dimensional analysis of the concave position and its related fast algorithm, and the optimal stretching position is not determined ...
