Checking tool and testing method for rear door and window step gap of body-in-white

Abstract

The invention relates to the field of car body assembling detection devices, and aims at providing a detection tool and a detection method for a jump and a gap between a back door and a back window of a white car body. The detection tool for the jump and the gap between the back door and the back window of the white car body comprises a base plate the bottom of which is provided with locating surfaces and at least one adsorption head, two locating pieces each of which is provided with a locating pin matched with a location hole positioned in a back quarter window frame, at least one surface difference gauge and at least one section gauge; and the two locating pieces are respectively positioned at the two sides of the rear end of the base plate and are fixedly connected with the base plate in a detachable manner. The detection tool for the jump and the gap between the back door and the back window of the white car body is simply and reliably, and is located by one surface and two pins, the detection tool for the jump and the gap between the back door and the back window of the white car body is high in detection precision and detection efficiency, and the detection method for the jump and the gap between the back door and the back window of the white car body is convenient to operate, and is stable and reliable.

Description

technical field [0001] The invention relates to the field of assembly detection devices for car bodies, in particular to a detection tool and detection method for the step difference gap between rear doors and windows of a body-in-white. Background technique [0002] The structure of the rear door and the rear triangular window of the car can be understood from a kind of car rear door structure disclosed by the utility model of the Chinese patent announcement number CN201816431U and a kind of automobile rear triangular window disclosed by the utility model of the Chinese patent announcement number CN202623860U; Installed on the body through a hinge, the rear triangular window is positioned and fixed by inserting two positioning pins into the two positioning holes on the rear triangular window frame of the vehicle body; The outer surface and the outer surface of the rear triangular window will form a step difference, and there will be a gap between the rear door and the oppos...

[0002] The structure of the rear door and the rear triangular window of the car can be understood from a kind of car rear door structure disclosed by the utility model of the Chinese patent announcement number CN201816431U and a kind of automobile rear triangular window disclosed by the utility model of the Chinese patent announcement number CN202623860U; Installed on the body through a hinge, the rear triangular window is positioned and fixed by inserting two positioning pins into the two positioning holes on the rear triangular window frame of the vehicle body; The outer surface and the outer surface of the rear triangular window will form a step difference, and there will be a gap between the rear door and the opposite side end surface of the rear triangular window; when the step difference and the gap are too large, there will be wind noise during the driving of the car, which will affect Driving comfort; according to the production process, the rear door of the car is installed on the body-in-white in the welding workshop, and the rear triangular window is installed in the subsequent process; after the rear triangular window is installed, if the outer surface of the rear door and the outer surface of the rear triangular window The surface step difference and the gap between the rear door and the opposite sides of the rear triangular window do not meet the requirements, and it is very troublesome to adjust the rear door to the correct position; currently, after the body-in-white is installed on the rear door of the welding workshop, the triangular window frame is used as a benchmark , using conventional inspection tools to detect the position of the outer surface and side end surface of the rear door to indirectly detect the step difference between the outer surface of the rear door and the outer surface of the rear triangular window and the gap between the rear door and the opposite side of the rear triangular window, there are measurement accuracy and The lack of low measurement efficiency; therefore, it is an urgent problem to design a gap inspection tool and detection method for rear doors and windows of the body-in-white with high measurement accuracy and measurement efficiency.
