Problems solved by technology

[0002] At present, there are mainly two detection methods for the existing engine hatch hinges. One is the scanning point method, which uses software to compare the hinge cloud with the digital model, and obtains the hinge error through measurement. The detection cycle is long and is not suitable for Quick detection of leaving the factory or entering the factory; the second method is to use conventional inspection tools to detect it, by setting a detection block with a plane on the base plate, after fixing the bracket of the hinge with the base plate, and then fixing the hinge The surface of the arm is attached to the plane of the detection block to detect whether there is any error in the installation plane and the installation hole of the hinge arm. The size of the hinge opening force

Embodiment Construction

[0031] The inspection tool involved in the present invention is to detect or evaluate whether the relevant design of the automobile bonnet hinge meets the standard requirements, by figure 1 As can be seen, the structure of the existing automobile bonnet hinge mainly includes two parts: one is a bracket 2 for connecting the vehicle body, which has two mounting holes 9, one of which is a round hole, One is an oblong hole, and the oblong hole is mainly used to compensate the error in the direction of the connecting line between the two holes; the other part is used to connect the hinge arm 5 of the engine compartment cover assembly, which also has two mounting holes 9, and the two mounting holes 9 is also an oblong hole and a round hole. The upper and lower end faces of the two mounting holes 9 of the hinge arm 5 are a plane, which ensures that when the mounting hole 9 is connected to the engine compartment cover assembly, it is connected to the engine compartment cover. The fit ...

Abstract

The invention relates to a detection device and particularly relates to an automobile engine hood hinge inspection tool. The automobile engine hood hinge inspection tool comprises a base plate (1), a fixing device and a measuring arm (3), wherein the fixing device is used for fixing a tray (2) of a hinge, which is used for connecting with an automobile body, on the base plate (1); the measuring arm (3) is rotatably connected with a support (4) fixed with the base plate (1); and the measuring arm is provided with a fitting plane (6) which is in fitted connection with the surface of a hinge arm (5), which is used for connecting with an engine hood hinge assembly. With the adoption of the scheme, the axis precision of a hinge connecting shaft can be detected; and rapid and high-precision inspection in in-factory and ex-factory process of the hinge is realized, and the size of an opening force of the hinge can be detected.
