Description

Technical Field

[0001] The present invention relates to the technical field of metal part bending correction, and particularly to a deformation amount detection and correction device for automobile crossbeam processing. Background Art

[0002] The automobile crossbeam is an important component in the vehicle body structure, mainly used to enhance the vehicle body rigidity, disperse the collision impact force, and support key components.

[0003] The processing of automobile crossbeams requires multiple processes including blanking, stamping, welding, and surface treatment.

[0004] During the processing of automobile crossbeams, deformations (such as bending, twisting, local depression, etc.) are common quality problems. There are many reasons for the generation of deformations, including stamping springback, welding deformation, heat treatment warping, machining deformation, residual stress deformation, etc.

[0005] If the deformation amount generated during the processing of automobile crossbeams is not corrected, it will affect the assembly accuracy, structural strength, or collision performance. Therefore, after the processing of automobile crossbeams is completed, necessary dimensional inspection and deformation amount correction are usually carried out to ensure its dimensional accuracy and assembly quality.

[0006] However, when the existing inspection and correction devices are used for the deformation amount detection and correction of automobile crossbeam processing, due to design defects, the following problems generally exist: 1. The conveying efficiency of automobile crossbeams is low, and the production line connection is not smooth. Specifically, the traditional conveying method relies on manual or single robotic arm for loading and unloading, with low efficiency and difficulty in seamless connection with the inspection and correction stations; the positioning accuracy of the crossbeam is insufficient, resulting in deviations in subsequent inspection or correction.

[0007] 2. The detection method is single, and the determination of the deformation amount is not comprehensive. Specifically, the traditional detection only relies on single-direction scanning, easily missing the dead corners of bending and twisting deformations; manually adjusting the detection position is time-consuming and has low accuracy.

[0008] 3. It is difficult to synchronize the torsion and bending corrections. Specifically, the traditional correction equipment requires step-by-step operation, with low efficiency; the control of the correction force is not precise, easily causing secondary deformation or material damage.

[0009] 4. The switching of multiple detection surfaces depends on manual intervention. Specifically, when multiple surfaces of the crossbeam need to be detected, manual flipping or replacement of fixtures is required, interrupting the process; the repeated positioning error affects the detection consistency.

[0010] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve. Summary of the Invention

[0011] In view of the defects in the prior art, the present invention provides a deformation detection and correction device for automobile crossbeam processing, so as to solve the problems of low automation, incomplete detection coverage, low correction efficiency, and fragmentation of multiple processes existing in the detection and correction device in the traditional technology when used for the deformation detection and correction of automobile crossbeam processing.
