DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0025] according to Figure 1-8 As shown, a vehicle trunk side panel 2 inspection fixture includes a testing platform 1, a testing body that cooperates with the side panel 2 is provided above the testing platform 1, a positioning component is also provided on the testing platform 1, the positioning component is used to support and position the side panel 2, and the end of the side panel 2 is fixed by a simulated piece, and the testing platform 1 is also provided with a first testing component for detecting the flatness of the end surface of the side panel 2 and a second testing component for detecting the flatness of the edge of the side panel 2. The first testing component includes a first testing block 3 located above the side panel 2, and the first testing block 3 is mounted on a rotating seat.

[0026] In the above specific embodiment, a simulated part is provided to simulate the installation environment of the side panel 2, and the side panel 2 is preliminarily positioned. At the same time, a positioning component is provided to further position the side panel 2, thereby ensuring the accuracy of the detection of the side panel 2. The first detection component and the second detection component are provided to detect the flatness of the edge and end face of the side panel 2. The first detection block 3 is used to detect the end face of the side panel 2. When a new side panel 2 needs to be replaced for detection, the first detection block 3 is rotated by the rotating seat, which is convenient for the staff to replace the side panel 2 for detection, thereby improving work efficiency and accurate detection.

[0027] The positioning assembly includes several first columns 4, and the positioning pins 5 pass through the holes on the side panels 2 and are connected to the first columns 4. The positioning pins 5 are provided with limit blocks 6 for detecting the contours of the holes on the side panels 2. If the holes on the side panels 2 are compatible with the limit blocks 6, the product is qualified, otherwise the product is unqualified.

[0028] The simulated part includes a pressing plate 7 , the lower end surface of the pressing plate 7 is matched with the side plate 2 , and the pressing plate 7 is detachably connected to the support column 8 .

[0029] The present embodiment provides a car trunk side panel inspection fixture, which is convenient for replacing the side panel 2 and improving the inspection efficiency of the side panel 2.
