Vehicle door inspection tool and method for matching detection of vehicle door inner panel and window frame

Abstract

The invention provides a vehicle door inspection tool, comprising: a base plate; a plurality of window frame positioning units installed on the base plate, a plurality of vehicle door inner panel positioning units, a window frame positioning pin and a vehicle door inner panel positioning pin; the window The frame positioning unit includes a window frame clamp and a window frame reference plane; the door inner panel positioning unit includes a door inner panel clamp and a door inner panel reference plane; the window frame reference plane and the window frame positioning pin can be Expanding and contracting in a direction perpendicular to the bottom plate; at least one window frame positioning unit is located at the overlapping position of the inner panel of the car door to be tested and the window frame to be tested. The present invention also provides a detection method for the compatibility between the inner panel of the door and the window frame by using the above-mentioned inspection tool for the door. The invention has the advantages of timely finding problems, strong versatility, small cost and occupied space.

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
