[0024] The present invention will be further described below with reference to the accompanying drawings:
[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, this utility model provides a device for preventing incorrect installation of rivet nuts on a car bumper, including a first anti-misinstallation mechanism 1 and a second anti-misinstallation mechanism 2. Both the first anti-misinstallation mechanism 1 and the second anti-misinstallation mechanism 2 include a bracket 11 and two limiting blocks 12, which are fixedly installed near the two ends of the bracket 11. Receiving grooves 121 are provided opposite to each other on the two limiting blocks 12, and the shape of the receiving grooves 121 is adapted to the shape of the car bumper 3. The first anti-misinstallation mechanism 1 also includes a first base plate 13, which is fixedly installed on the bracket 11, and the two limiting blocks 12 are respectively attached to the two ends of the first base plate 13. The first base plate 13 is machined with a first anti-misinstallation hole 131 and a second anti-misinstallation hole 132. The positions of the first anti-misinstallation hole 131 and the second anti-misinstallation hole 132 correspond to the groove positions on the side of the car bumper 3 where the first rivet nut 4 needs to be installed. The first rivet nut 4 is a hexagonal through-hole rivet nut M6*1.0. The second anti-misalignment mechanism 2 also includes a second base plate 21, which is fixedly mounted on the bracket 11. Two limiting blocks 12 are respectively attached to both ends of the second base plate 21. A third anti-misalignment hole 211 is machined on the second base plate 21. The position of the third anti-misalignment hole 211 corresponds to the groove position on the side of the car bumper 3 where the second rivet nut 5 needs to be installed. The specification of the second rivet nut 5 is a countersunk rivet nut M6*1.0.
[0026] like Figure 3 and Figure 4As shown, based on the above embodiment, the bracket 11 is further provided with a mounting groove 111, and the limiting block 12 is provided with a mounting hole 122. The mounting hole 122 mates with the mounting groove 111, and the mounting hole 122 and the mounting groove 111 are fixedly connected by bolts and nuts. The mounting groove 111 is in the shape of a straight line, and there are multiple mounting grooves 111 distributed parallel to each other along the length direction of the bracket 11. In this embodiment, four mounting grooves 111 are used.
[0027] like Figure 3 and Figure 4 As shown, based on the above embodiment, a mounting portion 133 is further fixedly provided on both the first substrate 13 and the second substrate 21. The mounting portion 133 is perpendicular to both the first substrate 13 and the second substrate 21. The mounting portion 133 and the first substrate 13, and the mounting portion 133 and the second substrate 21 can be integrally formed. The mounting portion 133 is machined with mounting holes 122. The mounting holes 122 of the mounting portions 133 of the first substrate 13 and the second substrate 21 are matched with the mounting groove 111 near the top of the bracket 11. The mounting holes 122 of the mounting portion 133 and the mounting groove 111 of the bracket 11 can be fixedly connected by bolts and nuts.
[0028] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, based on the above embodiment, there are further four first anti-misalignment holes 131. Each first anti-misalignment hole 131 corresponds to a groove position on the side of the car bumper 3 where a first rivet nut 4 needs to be installed, meaning that four first rivet nuts 4 need to be riveted at the four positions of the first anti-misalignment holes 131. There are two second anti-misalignment holes 132. Each second anti-misalignment hole 132 corresponds to two adjacent groove positions on the side of the car bumper 3 where two adjacent first rivet nuts 4 need to be installed, meaning that four first rivet nuts 4 need to be riveted at the two positions of the second anti-misalignment holes 132. The first anti-misalignment holes 131 and the second anti-misalignment holes 132 work together to achieve the requirement that a total of eight first rivet nuts 4 need to be riveted on the side of the car bumper 3. There are two third anti-misalignment holes 211. Each third anti-misalignment hole 211 corresponds to a groove position on the side of the car bumper 3 where a second rivet nut 5 needs to be installed, meaning that two second rivet nuts 5 need to be riveted at the two positions of the third anti-misalignment holes 211. The third anti-misalignment holes 211 achieve the requirement that a total of two second rivet nuts 5 need to be riveted on the side of the car bumper 3.
[0029] like Figure 5 and Figure 6As shown, based on the above embodiment, the first substrate 13 is further provided with a first label area 134 on its top for displaying an image of the first rivet nut 4 (hexagonal through-hole rivet nut M6*1.0); the second substrate 21 is provided with a second label area 212 on its top for displaying an image of the second rivet nut 5 (small countersunk rivet nut M6*1.0). By providing a conspicuous first label area 134 and second label area 212, workers are reminded to distinguish between the similar first rivet nut 4 and second rivet nut 5.
[0030] like Figures 1 to 6 As shown, during installation, the first anti-misalignment mechanism 1 is fixedly installed on a workbench via bracket 11, and the second anti-misalignment mechanism 2 is fixedly installed on another workbench via bracket 11. During operation, (1) the car bumper 3 to be riveted is first placed in the receiving groove 121 of the limiting block 12 of the first anti-misalignment mechanism 1; (2) then, according to the prompt of the first label area 134, the first rivet nut 4 is taken out, and then, according to the prompt of the first anti-misalignment hole 131 and the second anti-misalignment hole 132, the first rivet nut 4 is placed in the groove on the side of the car bumper 3 where the first rivet nut 4 needs to be installed; (3) then, eight first rivet nuts 4 are riveted in sequence on the side of the car bumper 3 using a rivet gun; (4) then, the car bumper 3 with the first rivet nuts 4 riveted is removed from the first rivet nut 4. (5) Remove the first rivet nut 4 from the anti-misalignment mechanism 1 and place it in the receiving groove 121 of the limiting block 12 of the second anti-misalignment mechanism 2; (6) Then, according to the prompt of the second label area 212, take the second rivet nut 5, and then, according to the prompt of the third anti-misalignment hole 211, put the second rivet nut 5 into the groove on the side of the car bumper 3 where the second rivet nut 5 needs to be installed; (7) Then, rivet the two second rivet nuts 5 on the side of the car bumper 3 in sequence with the rivet gun, and finally, remove the car bumper 3 from the second anti-misalignment mechanism 2 after the first rivet nut 4 and the second rivet nut 5 have been riveted. Note that the above is only a demonstration of the riveting process. It is possible to rivet the first rivet nut 4 first and then the second rivet nut 5, or to rivet the second rivet nut 5 first and then the first rivet nut 4, because the first anti-misalignment mechanism 1 and the second anti-misalignment mechanism 2 distinguish the first rivet nut 4 and the second rivet nut 5, and there will be no problem of using the wrong rivet nut specification.
[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Those skilled in the art should understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and all such changes should be covered within the protection scope of this utility model. The protection scope of this utility model is defined by the claims and their equivalents.
