It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] refer to Figure 1-2 and Figure 5-7 The automotive rear floor assembly inspection fixture of this embodiment includes a base 1. A plurality of first mounting seats 10 are fixedly connected to the center of the top side of the base 1. A support mechanism 11 is provided on the top of each first mounting seat 10 for supporting the workpiece to be tested. The support mechanism 11 includes a plurality of contouring top blocks 1101. A third limiting hole 1102 is provided on the top of each contouring top block 1101. A plurality of second mounting seats 2 are fixedly connected around the top edge of the base 1 around the plurality of first mounting seats 10. A contouring profile plate 3 is fixedly connected to the top of each second mounting seat 2 for contouring and limiting the workpiece to be tested. A plurality of third mounting seats 4 and fourth mounting seats 6 are fixedly connected around the top edge of the base 1 around the contouring profile plate 3. The top of each third mounting seat 4... The first clamping assembly 5 is provided for clamping and fixing the workpiece to be tested. The top of the fourth mounting base 6 is provided with a flipping mechanism 7 for inspecting the workpiece. Several positioning seats 12 are provided on the inner side of the contour plate 3. The support mechanism 11 also includes a fixed seat 1103 and several C-shaped clamps 1105. The contour top block 1101 and the fixed seat 1103 are fixedly connected to the first mounting base 10. The top of the fixed seat 1103 is provided with a second clamping assembly 1104. It also includes several positioning pins and detection pins. The positioning pins and detection pins are detachably connected to the first limiting hole 705, the second limiting hole 908 and the third limiting hole 1102 respectively. The first clamping assembly 5 and the second clamping assembly 1104 are both clamps. During testing, ensure that each flipping mechanism 7 and the first clamping assembly 5 are in the open state. Then, place the workpiece to be tested at the bottom of the middle and rear floor assembly onto the corresponding contour plate 3. The positioning seat 12 on the inner side of the contour plate 3 is used to initially position the workpiece. During placement, the bottom of the workpiece is supported by the corresponding contour block 1101, ensuring that the contour of the workpiece fits against the contour plate 3. Then, close the first clamping assembly 5 on the outer side of the contour plate 3 to initially position the workpiece. Next, close the second clamping assembly 1104 on the side of the contour block 1101, and finally, use the C-clamp 11... 05. Further clamp and fix the workpiece to the contour block 1101. At this time, the through hole on the surface of the workpiece matches the position of the third limiting hole 1102. Insert the positioning pin and the detection pin into the corresponding position of the third limiting hole 1102 to detect the workpiece. Repeat the above steps to detect the workpiece at the bottom of the middle and rear floor assembly. After the workpiece at the bottom of the middle and rear floor assembly is detected, remove the workpiece at the bottom and then install the workpiece to be tested on the top of the middle and rear floor assembly to the corresponding position. The installation steps are the same as above. Then close the flipping mechanism 7, then install the upper detection mechanism 9, and finally detect the workpiece to be tested on the top of the middle and rear floor assembly through the positioning pin and the detection pin.

[0026] refer to Figure 4A pair of fifth mounting seats 8 are fixedly connected to the opposing edges on both sides of the top of the base 1. An upper detection mechanism 9 is detachably provided on the top of the fifth mounting seat 8. The upper detection mechanism 9 includes a crossbar 901. A pair of connecting seats 902 are fixedly connected to the bottom of both ends of the crossbar 901. Several limiting blocks 903 are fixedly connected to the side wall of the fifth mounting seat 8. Several side connecting plates 904 are fixedly connected to the side wall of the crossbar 901. Several side contour plates 905 are fixedly connected to the side wall of the side connecting plates 904. An upper connecting plate 906 is fixedly connected to the top of the crossbar 901. An upper contour plate 907 is fixedly connected to the end of the upper connecting plate 906 away from the crossbar 901. A second limiting hole 908 is opened on the top of the upper contour plate 907. When the upper detection mechanism 9 is installed, the connecting seats 902 at both ends of the crossbar 901 are placed on the top of a pair of fifth mounting seats 8 respectively. The position of the connecting seats 902 is limited by the limiting block 903. At this time, the upper contour plate 907 and the side contour plate 905 match the contour of the workpiece to be tested at the corresponding position, and the second limiting hole 908 matches the position of the through hole on the surface of the workpiece to be tested.

[0027] refer to Figure 3 The flipping mechanism 7 includes a flipping base 701, a flipping plate 702 rotatably connected to the top of the flipping base 701, a fixing plate 703 fixedly connected to the other end of the flipping plate 702, and a plurality of contour blocks 704 fixedly connected to the side wall of the fixing plate 703. The top of each contour block 704 has a plurality of first limiting holes 705. When the flipping mechanism 7 is closed, the flipping plate 702 is rotated, causing the fixing plate 703 and the contour blocks 704 to rotate toward the workpiece to be measured until the bottom of the contour blocks 704 abuts against the workpiece, so that the position of the first limiting holes 705 matches the position of the through holes on the surface of the workpiece.

[0028] Working principle: During testing, ensure that each flipping mechanism 7 and the first clamping assembly 5 are in the open state. Then, place the workpiece to be tested at the bottom of the middle and rear floor assembly on the corresponding shape of the contour plate 3. The positioning seat 12 on the inner side of the contour plate 3 is used to initially position the workpiece. During placement, the bottom of the workpiece is supported by the corresponding contour block 1101, so that the contour of the workpiece fits with the contour plate 3 at the corresponding position. Then, close the first clamping assembly 5 on the outer side of the contour plate 3 at the corresponding position to initially position the workpiece. Then, close the second clamping assembly 1104 on the side of the contour block 1101. Finally, the C-shaped clamp 1105 is used to further clamp and fix the workpiece to the contour block 1101. At this time, the position of the through hole on the workpiece surface matches the position of the third limiting hole 1102. Insert the positioning pin and the detection pin into the corresponding position of the third limiting hole 1102 to test the workpiece. Repeat the above steps to test the workpiece at the bottom of the middle and rear floor assembly.

[0029] After the workpiece at the bottom of the middle and rear floor assembly is inspected, it is disassembled. Then, the workpiece to be tested at the top of the middle and rear floor assembly is installed in the corresponding position, following the same installation steps. Next, the flipping mechanism 7 is closed. At this time, the flip plate 702 is rotated, causing the fixing plate 703 and the contour block 704 to rotate towards the workpiece to be tested until the bottom of the contour block 704 abuts against the workpiece to be tested, so that the position of the first limiting hole 705 matches the position of the through hole on the surface of the workpiece to be tested. Then, the upper detection mechanism 9 is installed. During installation, the connecting seats 902 at both ends of the crossbar 901 are placed on the top of a pair of fifth mounting seats 8, and the position of the connecting seats 902 is limited by the limiting block 903. At this time, the upper contour plate 907 and the side contour plate 905 match the contour of the workpiece to be tested at the corresponding position, and the second limiting hole 908 matches the position of the through hole on the surface of the workpiece to be tested. Finally, the positioning pin and the detection pin are inserted into the corresponding first limiting hole 705 and second limiting hole 908 to inspect the workpiece to be tested at the top of the middle and rear floor assembly.

[0030] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
