Ultrasonic wave detection device for thinning rate of body in white

Abstract

The invention relates to an ultrasonic wave detection device for a thinning rate of a body in white. The ultrasonic wave detection device comprises ultrasonic wave probes, a data acquisition and management system, a microcomputer, a connecting cable and a clamp system arranged corresponding to the body in white; and software comprise a signal analysis and process system. The body in white is fixed on a rack through a clamp, ultrasonic waves generated by a plurality of ultrasonic wave probes are reflected on the surface of the body in white, the microcomputer receives ultrasonic waves reflected from different detection points, and the data of the different detection points are calculated so as to obtain the thinning rate of parts. The invention provides a whole set of equipment for the design of the parts and the consistency detection in the practical manufacturing process, the thinning rate of the parts can be detected effectively, the body in white, which is thinned excessively, is prevented from entering the next production link, the time needed by the road test is reduced, the development process of a finished automobile is shortened, the product quality of enterprises is improved, and simultaneously, the unqualified automobiles on the market are reduced.

Description

technical field [0001] The invention relates to an ultrasonic detection device for the thinning rate of a body in white. Background technique [0002] In the current automobile manufacturing and production, stamping is the main process and manufacturing method of body-in-white parts. The stamping performance of its components determines the performance of the body in white. For example, in the stamping process, the excessive thinning rate of the parts affects the stiffness, strength and modal characteristics of the whole vehicle, so that the performance of the manufactured prototype vehicle is inconsistent with the design performance. In the traditional detection of the thinning rate of parts, the thinning rate of parts is obtained by marking on the sheet before and after stamping. However, this method is relatively inefficient and is not suitable for large-scale batch production of different parts. The thinning rate detection proposed by the present invention is based on ...

AI Technical Summary

Problems solved by technology

There are many unpredictable factors in the manufacture of auto parts, which lead to tiny cracks or failures in auto parts, and the parts are the main stress-bearing parts of the vehicle structure, so the parts are welded or assembled into The strength and fatigue durability of the car body are greatly reduced

The quality and design consistency of the manufactured body-in-white not only makes the manufactured prototype affect the road test test, verification, and decision-making, but also affects the quality of the vehicle put into the market
