Vehicle door checking tool and method for detecting matching degree of inner vehicle door plate and window frame

Abstract

The invention provides a vehicle door checking tool. The vehicle door checking tool comprises a bottom plate, and a plurality of window frame positioning units, a plurality of inner vehicle door plate positioning units, a window frame positioning pin, and an indoor vehicle door plate positioning pin which are mounted on the bottom plate, wherein each window frame positioning unit comprises a window frame clamp and a window frame reference plane; each inner vehicle door plate positioning unit comprises an inner vehicle door plate clamp and an inner vehicle door plate reference plane; both the window frame reference planes and the window frame positioning pin can stretch and retract in the direction which is perpendicular to the bottom plate; at least one window frame positioning unit is positioned at the lapping position between the inner vehicle door plate to be detected and the window frame to be detected. The invention further provides a method for detecting the matching degree of the inner vehicle door plate and the window frame by adopting the vehicle door checking tool. The vehicle door checking tool and the method have the advantages that a problem is discovered timely; the university is high; the cost is low; the occupied space is small.

Description

technical field [0001] The invention relates to the field of automobile assembly detection, in particular to a vehicle door inspection tool and a method for detecting the matching between a vehicle door inner panel and a window frame by using the vehicle door inspection tool. Background technique [0002] Passenger car doors can generally be divided into one-piece doors and split doors. The one-piece door means that the inner and outer panels of the door are integrally stamped and formed, and are connected to the glass run channel through welding and edging. The split door, that is, the door window frame, is formed by rolling technology and connected to the inner and outer panels of the door by welding. [0003] Since the state of split door and window frames is prone to fluctuations, product quality problems frequently occur. In order to avoid this problem, the window frame manufacturer has developed two sets of window frame inspection tools to control product quality, on...

AI Technical Summary

Problems solved by technology

The disadvantages of the independent setting of the window frame inspection tool and the door inspection tool are:

[0005] (1) The car door adopts two sets of inspection tools, one for detecting the window frame and the other for detecting the inner panel of the door. It is impossible to perform quality inspection on the matching between the window frame and the inner panel of the door, and due to the manufacturing of the inspection tool itself error, the test data obtained after the window frame and door inner panel are tested separately is difficult to quickly expose the quality problems of the product

[0006] (2) Welding production lines are mostly flexible production of multiple models, and the storage of inspection tools for all models requires a lot of space

[0007] (3) Two sets of inspection tools are developed for each model, and the investment cost of tooling development is relatively high
