Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a front bumper assembly inspection tool. Background Technology

[0002] During the manufacturing process of the front bumper assembly of a car, the peripheral surface and the mounting holes on the inner side of the front bumper assembly need to be inspected for position. The inspected parts are the periphery of the product and the mounting holes. The periphery of the product is arc-shaped and connected end to end, while the mounting holes are located on the back or side of the product.

[0003] Because the front bumper assembly is curved around the perimeter, and the mounting holes are in the three-dimensional space, after the product is installed, there are requirements for the fit clearance and surface difference of the curved edges around it, and the appearance requirements are high. Therefore, it is necessary to accurately check the outline dimensions of the product mounting surface. In addition, the position of the mounting holes on the inner side of the product is also important, and the mounting holes need to be precisely positioned to ensure that the product quality meets the requirements.

[0004] Measuring contour dimensions using existing measuring tools (vernier calipers, steel rulers, micrometers) is extremely difficult and time-consuming. Inconsistent measurement positions by different personnel can lead to significant errors in the results, resulting in low reliability and impacting product quality assessment. Furthermore, due to the large production volume, existing measuring instruments cannot complete timely inspections, affecting product delivery. Additionally, existing measuring instruments such as vernier calipers cannot effectively measure the contour dimensions of mating surfaces and other profiled areas, hindering product quality inspection.

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] Please see Figures 1 to 6 , Figure 1 A schematic diagram of the structure of a front bumper assembly inspection fixture provided in an embodiment of this utility model. Figure 1 The front bumper assembly inspection fixture includes: a base plate 10, a rollover detection mechanism 20, an end detection mechanism 30, and a locking mechanism 40. The rollover detection mechanism 20 includes multiple sets of first rollover detection components 21 symmetrically distributed in an arc shape, and second rollover detection components 22 located on the left and right sides. The first rollover detection components 21 have a first surface detection block 21c, and the second rollover detection components 22 have a second surface detection block 22c. The end detection mechanisms 30 are symmetrically arranged on the left and right sides of the base plate 10, and each end detection mechanism 30 has a third surface detection block 32. The locking mechanism 40 is disposed on the base plate 10 and located in front of the rollover detection mechanism 20, and is symmetrically distributed in an arc shape. Each locking mechanism 40 includes a first locking component 41, a second locking component 42, and a third locking component 43 arranged sequentially in a direction away from the center.

[0023] Specifically, the base plate 10 supports the rollover detection mechanism 20, the end detection mechanism 30, and the locking mechanism 40. The rollover detection mechanism 20 is located on the base plate 10 and includes multiple sets of first rollover detection components 21 and second rollover detection components 22 located on the left and right sides. The peripheral surfaces of the front bumper assembly 100 can be detected by the first surface detection blocks 21c and the second surface detection blocks 22c on the rollover detection mechanism 20. The end detection mechanism 30 is located on the left and right sides of the base plate 10. The surface detection blocks 32 of the end detection mechanism 30 can detect the surface of the left and right ends of the front bumper assembly 100. The first surface detection blocks 21c, the second surface detection blocks 22c, and the third surface detection blocks 32 together form a constraint space for the front bumper assembly 100.

[0024] By setting up a flipping detection mechanism 20 and an end detection mechanism 30, the peripheral surface of the front bumper assembly 100 is limited to facilitate the detection of the peripheral surface; by setting up a locking mechanism 40, the front bumper assembly 100 is locked to facilitate the detection operation.

[0025] See Figure 4 and Figure 5 In some embodiments, the first flip detection component 21 includes a first support 21a and a first flip member 21b disposed on the first support 21a. The first flip member 21b is provided with a first surface detection block 21c. Specifically, each first support 21a is set at the same height on the base plate 10, and each first support 21a is provided with a support column 21d. The first flip member 21b is disposed on the support column 21d, and the first flip member 21b includes a fixed plate and a flip plate rotatably disposed on the fixed plate. The attitude of the flip plate can be adjusted by rotating the flip plate. The first surface detection block 21c is disposed on the flip plate of the first flip member 21b. By adapting the position of the first surface detection block 21c to the corresponding position of the front bumper assembly 100, the gap or discontinuity of the peripheral surface of the front bumper assembly 100 can be detected by using a gap gauge or a discontinuity gauge.

[0026] See Figure 6 In some embodiments, the second flip detection component 22 includes a second support 22a and a second flipping member 22b disposed on the second support 22a. A second surface detection block 22c is disposed on the second flipping member 22b. The height of the second support 22a is greater than the height of the first support 21a. Specifically, the greater height of the second support 22a than the first support 21a facilitates the placement of a third surface detection block 32 on the second support 22a. The second flipping member 22b is directly disposed on the second support 22a and includes a fixed plate and a flipping plate rotatably disposed on the fixed plate. The flipping plate's posture can be adjusted by rotating it. The second surface detection block 22c is disposed on the flipping plate of the second flipping member 22b. By adapting the second surface detection block 22c to the corresponding position of the front bumper assembly 100 (i.e., near the edge of the front bumper assembly 100), gaps or gaps can be detected on the peripheral surfaces of the front bumper assembly 100 using a gap gauge or a gap gauge.

[0027] See Figure 4In the above embodiment, the first rollover detection component 21 is provided in three sets. The structure of the first surface detection block 21c on each set of the first rollover detection component 21 is different from that of each other, and the structure of each first surface detection block 21c and the second surface detection block 22c is adapted to the periphery of the front bumper assembly 100. Specifically, in this example, three sets of first rollover detection components 21 are provided, namely the first set of first rollover detection components 211, the second set of first rollover detection components 212 and the third set of first rollover detection components 213 arranged sequentially from the middle of the base plate 10 to both sides, and arranged in an arc-shaped interval. The structure of the first surface detection block 21c in each set of first rollover detection components 21 is different from that of each other, and is adapted to the periphery of the front bumper assembly 100 according to its position.

[0028] See Figure 1 and Figure 6 It should be noted that the end detection mechanism 30 also includes a first positioning card part 31 and a second positioning card part 33, with the first positioning card part 31 located above the second positioning card part 33. The first positioning card part 31 is disposed on the second support 22a, and the second positioning card part 33 is disposed on the base plate 10 and located in front of the second support 22a. Specifically, by setting the first positioning card part 31 and the second positioning card part 33, the left and right ends of the front bumper assembly 100 are positioned, so that the front bumper assembly 100 can be fixed on the front bumper assembly fixture, thereby facilitating subsequent inspection of the front bumper assembly 100.

[0029] See Figure 6 In the above embodiment, the front wall of the second support 22a is further provided with a third profile detection block 32, and the third profile detection block 32 is located between the first positioning card part 31 and the second positioning card part 33. Specifically, the third profile detection blocks 32 located on the two second supports 22a on the left and right sides are used to adapt to the end profiles of the left and right ends of the front bumper assembly 100, so that the gap or gap of the end profile of the front bumper assembly 100 can be detected by using a gap gauge or a gap gauge.

[0030] See Figure 7In some embodiments, the first locking assembly 41 has two first locking holes 411, which are coaxially arranged and have a height difference in the vertical direction; the second locking assembly 42 has one second locking hole 421 arranged vertically; and the third locking assembly 43 has two third locking holes 431, which are parallel and have a height difference in the vertical direction. Specifically, the first locking assembly 41, the second locking assembly 42, and the third locking assembly 43 are arranged outwards in sequence, and their heights increase sequentially. The specifications of the first locking holes 411, the second locking holes 421, and the third locking holes 431 can be the same or different, depending on the required specifications. By setting the first locking holes 411, the second locking holes 421, and the third locking holes 431, the front bumper assembly 100 is locked onto the gauge.

[0031] Understandably, the base plate 10 is also movably provided with locking pins for fitting the first locking hole 411, the second locking hole 421, and the third locking hole 431. A connecting rope (not shown in the figure) connects the locking pins to the base plate 10. Specifically, in this example, multiple locking pins can be provided according to different specifications of the first locking hole 411, the second locking hole 421, and the third locking hole 431, so that the front bumper assembly 100 can be fixed to the fixture by fitting different locking pins with the corresponding locking holes. Since the locking pins are set on the base via connecting ropes, they can be easily operated to lock the corresponding first locking hole 411, second locking hole 421, and third locking hole 431 during use.

[0032] See Figure 3 In the above embodiments, both the first locking assembly 41 and the third locking assembly 43 have elastic detection pins 50, and at least a portion of the first flip detection assembly 21 has multiple elastic detection pins 50, with the pins of each elastic detection pin 50 being parallel to each other. Specifically, the elastic detection pins 50 are configured as spring detection pins. After the front bumper assembly 100 is installed on the inspection tool, the corresponding holes on the front bumper assembly 100 can be checked by pressing the elastic detection pins 50. In this example, elastic detection pins 50 are provided at both the first locking assembly 41 and the third locking assembly 43, and multiple elastic detection pins 50 are provided on both the first group of first flip detection components 211 and the second group of first flip detection components 212 in the first flip detection assembly 21. During inspection, the position of each mounting hole on the front bumper assembly 100 can be detected by pressing the elastic detection pins 50.

[0033] See Figure 1 , Figure 2 It's worth mentioning that the front bumper assembly inspection tool also includes independently set tow hook cover hand block 60, left fog light assembly hand block 70, right fog light assembly hand block 80, and driving trim hand block 90. ​​For details, please refer to [link / reference]. Figure 1 and Figure 2 The base plate 10 can be provided with storage positions for the tow hook cover handle 60, the left fog light assembly handle 70, the right fog light assembly handle 80, and the driving light strip handle 90. In this example, the storage positions for the left fog light assembly handle 70, the right fog light assembly handle 80, and the driving light strip handle 90 are all located behind the flip detection mechanism 20, and the storage position for the driving light strip handle 90 is located between the storage positions for the left fog light assembly handle 70 and the right fog light assembly handle 80; the tow hook cover handle 60 is placed in front of the locking mechanism 40 on the left. In other examples, the positions of each storage position can be adjusted as needed. See reference. Figure 8 The tow hook cover hand block 60 is used to check the dimensions of the tow hook hole area of ​​the front bumper assembly 100; see reference. Figure 9 and Figure 10 The left fog light assembly handheld block 70 and the right fog light assembly handheld block 80 are used to detect the mounting hole positions of the fog lights at both ends of the front bumper assembly 100 and the dimensions of the fog light frames; see reference. Figure 11 The handheld block 90 for the driving bright strip is used to detect the hole positions and edge dimensions of the driving bright strip installation area on the front bumper assembly 100.

Figure 1 , Figure 2 , Figure 12 and Figure 13 ), including the following steps: S1: First, open all the flip-up detection mechanisms 20 of the front bumper assembly inspection fixture; S2: Insert both ends of the front bumper assembly 100 into the first positioning clip 31 and the second positioning clip 33 on both sides; S3: Use locking pins to lock the first locking hole 411, the second locking hole 421 and the third locking hole 431; S4: Close all flip detection mechanisms 20; S5: Press each elastic detection pin 50 to check the position of each mounting hole of the front bumper assembly 100. S6: Use a gap gauge and a gap gauge to test the gaps and gaps of the parts around the front bumper assembly 100 that are equipped with the first surface detection block 21c, the second surface detection block 22c and the third surface detection block 32; S7: After the inspection is completed, open all the flip inspection mechanisms 20, release the locking pins, and remove the front bumper assembly from the front bumper assembly fixture; S8: Use the tow hook cover hand block 60, left fog light assembly hand block 70, right fog light assembly hand block 80, and driving bright strip hand block 90 to inspect the corresponding parts; S9: Reset the locking pin, the flip detection mechanism 20, and all the hand blocks (tow hook cover hand block 60, left fog light assembly hand block 70, right fog light assembly hand block 80, driving bright strip hand block 90), etc.

[0035] In summary, the front bumper assembly inspection fixture proposed in this utility model, by setting up a flipping inspection mechanism 20 and an end inspection mechanism 30, limits the peripheral surface of the front bumper assembly 100 to facilitate the inspection of the peripheral surface; by setting up a locking mechanism 40, it locks the front bumper assembly 100 to facilitate the inspection operation; furthermore, by setting up multiple elastic inspection pins 50, it can detect the hole positions of multiple inner mounting holes of the front bumper assembly 100. Only one front bumper assembly inspection fixture is needed to detect the mating dimensions of the front bumper assembly 100, which reduces the cost of purchasing standard measuring tools, enables rapid detection of product dimensions, saves a lot of inspection time, improves production efficiency, and ensures the quality of produced products.
