[0002] With the booming development of the automotive manufacturing industry and the increasing popularity of automobiles, people have higher and higher requirements for the quality of opening and closing components. Both objective evaluation and subjective experience are key points of concern for car owners. Therefore, higher requirements are placed on every component during the automobile manufacturing process.

[0003] The fuel filler / charging port cover assembly is located on the side of the vehicle body. Whether the fuel filler / charging port cover maintains an integrated and aesthetically pleasing appearance with the outer side panel, and whether it allows for smooth opening and closing, are important indicators of vehicle quality. The fuel filler / charging port cover assembly consists of three main parts: the outer panel, the inner panel, and the hinge.

[0004] Since there are many mounting points on the refueling / charging port hinge that require spatial position measurement, under current technological conditions, it is possible to carry out dimensional inspection using traditional inspection methods and three-dimensional measuring equipment. However, the measurement efficiency is low, the measurement frequency is very low, and it is difficult to ensure the consistency of the production process. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] This application discloses a novel automotive refueling and charging port hinge inspection tool. (Refer to...) Figure 1 The hinge 20 to be tested includes a cover 201 and a hinge arm 202 fixed to one end of the cover 201. A hinge hole 21 is provided through the hinge arm 202. Three parts to be tested are evenly distributed on both the upper and lower sides of the cover 201, namely, a first detection part 22, a second detection part 23, a third detection part 24, a fourth detection part 25, a fifth detection part 26, and a sixth detection part 27. A seventh detection part 28 to be tested is provided at the end of the cover 201 away from the hinge arm 202. The first detection part 22, the second detection part 23, the third detection part 24, the fourth detection part 25, the fifth detection part 26, and the sixth detection part 27 not only require the use of... Figure 2 The surface difference table 29 in the table is used to check the positional accuracy of its upper surface. Further testing is required using... Figure 3 The gap gauge 30 in the middle detects the position of its side; the seventh detection unit 28 needs to use Figure 3 The gap in the table 30 is used to detect the position of its side.

[0027] When using the surface difference table 29 and clearance table 30 to inspect the seven parts to be inspected on the hinge 20, it is necessary to set the stabilizer position of the hinge 20, referring to... Figure 4 , Figure 5 and Figure 6 A novel automotive refueling and charging port hinge inspection tool includes a base 1 and a support mechanism. Two inspection brackets 2 are spaced apart on the base 1 along its width direction. The support mechanism includes a first positioning bracket 4 and a second positioning bracket 5 fixed on the base 1. The first positioning bracket 4 and the second positioning bracket 5 are spaced apart along the length direction of the base 1 and are located on both sides of the inspection bracket 2, so that when the hinge 20 is mounted between the first positioning bracket 4 and the second positioning bracket 5, the two inspection brackets 2 are located on both sides of the hinge 20.

[0028] Reference Figure 4 , Figure 5 and Figure 6The first positioning bracket 4 includes two supports 41 spaced apart along the length of the base 1, with a pin 42 movably inserted between the two supports 41. When positioning the hinge 20, the hinge arm 202 of the hinge 20 is placed between the two supports 41, aligning the hinge hole 21 on the hinge arm 202 with the through hole on the support 41 for the pin 42. Then, the pin 42 is passed through the two supports 41 and the hinge hole 21 on the hinge arm 202, thus positioning one end of the hinge 20 on the first positioning bracket 4. At this time, the two adjacent sides of the two supports 41 are respectively in contact with the two sides of the end of the hinge arm 202. The second positioning bracket 5 is an L-shaped positioning block, fixed to the base 1 by screws. After one end of the hinge 20 is positioned on the first positioning bracket 4, rotating the hinge 20 causes the other end of the hinge 20 to rotate and mount on the second positioning bracket 5.

[0029] To further ensure that hinge 20 can be stably mounted between the first positioning bracket 4 and the second positioning bracket 5, refer to Figure 4 , Figure 5 and Figure 6 A column 16 is vertically fixed on the base 1, located on the side of the second positioning bracket 5 away from the first positioning bracket 4. A rotating arm 17 is rotatably connected to the top of the column 16. The rotating arm 17 is located above the second positioning bracket 5 and can rotate around the column 16 in a direction closer to / away from the second positioning bracket 5. A pressure head 18 is installed at the end of the rotating arm 17 away from the column 16. When the hinge 20 is positioned between the first positioning bracket 4 and the second positioning bracket 5, rotating the rotating arm 17 towards the second positioning bracket 5 causes the pressure head 18 on the rotating arm 17 to press one end of the hinge 20 firmly onto the second positioning bracket 5.

[0030] To avoid pressure damage to hinge 20 caused by pressure head 18, refer to Figure 4 , Figure 5 and Figure 6 The pressure head 18 includes a rod 181 vertically fixed to the end of the rotating arm 17 and a flexible sleeve 182 sleeved on the end of the rod 181. The flexible sleeve 182 can be made of rubber, nylon, or other materials. To facilitate the rotation of the rotating arm 17, a lever 19 for driving the rotating arm 17 to rotate is fixed on the side of the rotating arm 17 away from the flexible sleeve 182.

[0031] After the hinge 20 is stably installed, the seven parts on the hinge 20 to be inspected need to be tested using the surface difference table 29 and the clearance table 30. To ensure the stability of the position of the surface difference table 29 and the clearance table 30 during the inspection process, refer to... Figure 4 , Figure 5 and Figure 6The base 1 is also equipped with a positioning mechanism 6, which includes a support 61 fixed to the base 1 and a positioning plate 62 with one end mounted on the support 61. The support 61 is located on the side of the second positioning bracket 5 away from the first positioning bracket 4. A rotating groove 11 is provided on the top of the support 61, and a rotating shaft 12 is provided in the rotating groove 11. A rotating plate 13 is connected to the rotating shaft 12, and the rotating plate 13 is rotatably mounted on the top of the support 61 via the rotating shaft 12. One end of the positioning plate 62 is connected to the rotating plate 13 by screws. A hinge 20 is mounted between the first positioning bracket 4 and the second positioning bracket 5. The positioning plate 62 can rotate towards / away from the hinge 20 under the support of the support 61, the rotating shaft 12, and the rotating plate 13.

[0032] Reference Figure 4 , Figure 5 and Figure 6 A threaded abutment bolt 15 is threaded through the rotating plate 13, and an abutment joint 14 is fixed to the end of the abutment bolt 15. When the positioning plate 62 is flipped above the hinge 20, and the abutment joint 14 abuts against the bottom wall of the rotating groove 11, the tilt angle of the positioning plate 62 is adjusted by rotating the abutment bolt 15, so that the positioning plate 62 is horizontally mounted above the hinge 20. The first detection part 22, the second detection part 23, the third detection part 24, the fourth detection part 25, the fifth detection part 26, and the sixth detection part 27 are all located below the positioning plate 62 and close to the edge of the positioning plate 62. The outer surfaces of the first detection part 22, the second detection part 23, the third detection part 24, the fourth detection part 25, the fifth detection part 26, and the sixth detection part 27 on the side away from the middle of the hinge 20 are all exposed on the positioning plate 62. At this time, there are gaps between the positioning plate 62 and the two detection brackets 2, and between the positioning plate 62 and the first positioning bracket 4, for the gap gauge 30 to perform detection.

[0033] Reference Figure 4 , Figure 5 and Figure 6 Both testing brackets 2 have a first positioning hole 3 on their top for positioning the gap gauge 30. There are three sets of first positioning holes 3, and the three sets of positioning holes correspond one-to-one with the three parts to be tested on the upper / lower side of the cover 201. When the gap gauge 30 is inserted into the three sets of first positioning holes 3 of the two testing brackets 2 one by one, the testing end of the gap gauge 30 can abut against the side of the first testing part 22, the second testing part 23, the third testing part 24, the fourth testing part 25, the fifth testing part 26 and the sixth testing part 27 near the testing bracket 2, thereby detecting the position of the above six parts to be tested.

[0034] Reference Figure 4 , Figure 5 and Figure 6The top of each of the two supports 41 of the first positioning bracket 4 is provided with a third positioning hole 10 for positioning the gap gauge 30. When the gap gauge 30 is inserted into the third positioning hole 10 on the top of the two supports 41 one by one, the detection end of the gap gauge 30 can abut against the side of the third detection part 24 and the fourth detection part 25 near the first positioning bracket 4, respectively, so as to detect the position of the two parts to be detected.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The positioning plate 62 has a second positioning hole 7 in the middle for positioning the gap gauge 30. The positioning plate 62 has detection holes 9 on both sides of the second positioning hole 7 for the gap gauge 30 to perform detection. The two detection holes 9 are spaced apart along the length of the base plate. When the gap gauge 30 is inserted into the second positioning hole 7, the detection end of the gap gauge 30 can abut against the side of the seventh detection unit 28 near the first positioning bracket 4, thereby detecting the position of the seventh detection unit 28.

[0036] Reference Figure 4 , Figure 5 and Figure 6 The positioning plate 62 is also provided with insertion holes 8 for the surface difference meter 29 to perform insertion detection. Multiple insertion holes 8 are provided; in this embodiment, six insertion holes 8 are provided. All six insertion holes 8 are vertically inserted through the positioning plate 62, and each of the six insertion holes 8 corresponds one-to-one with the first detection section 22, the second detection section 23, the third detection section 24, the fourth detection section 25, the fifth detection section 26, and the sixth detection section 27. When the positioning plate 62 is horizontally mounted above the hinge 20 under the adjustment of the abutment bolt 15, the six insertion holes 8 are located directly above the first detection section 22, the second detection section 23, the third detection section 24, the fourth detection section 25, the fifth detection section 26, and the sixth detection section 27. At this time, the surface difference meter 29 can be inserted into the six insertion holes 8 one by one, so that the detection end of the surface difference meter 29 can accurately detect the position of the top surface of the first detection unit 22, the second detection unit 23, the third detection unit 24, the fourth detection unit 25, the fifth detection unit 26 and the sixth detection unit 27.

[0037] The implementation principle of a novel automotive refueling and charging port hinge inspection tool according to an embodiment of this application is as follows: First, the hinge arm 202 of the hinge 20 is rotated and mounted on the first positioning bracket 4 using the pin 42. Then, the hinge 20 is rotated so that the other end of the hinge 20 rotates and is mounted on the second positioning bracket 5. Finally, the lever 19 drives the rotating arm 17 to rotate in the direction of the hinge 20, so that the rotating arm 17 presses one end of the hinge 20 onto the second positioning bracket 5 through the pressure head 18 at its end. At this time, the hinge 20 is stably mounted between the first positioning bracket 4 and the second positioning bracket 5.

[0038] After the hinge 20 is stably installed, the position of the seven parts to be tested on the hinge 20 needs to be checked. First, the face difference gauge 29 and the gap gauge 30 are calibrated. Then, the positioning plate 62 is rotated towards the hinge 20. When the positioning plate 62 is flipped above the hinge 20 and the abutment 14 abuts against the bottom wall of the rotating groove 11, the tilt angle of the positioning plate 62 is adjusted by rotating the abutment bolt 15, so that the positioning plate 62 is horizontally installed above the hinge 20. Next, the gap gauges 30 are inserted one by one into the three sets of first positioning holes 3 of the two testing brackets 2. The testing ends of the gap gauges 30 can respectively abut against the sides of the first testing part 22, the second testing part 23, the third testing part 24, the fourth testing part 25, the fifth testing part 26, and the sixth testing part 27 near the testing bracket 2, thereby detecting the position of the above six parts to be tested. Then, the gap gauges 30 are inserted one by one into the third positioning holes 10 on the top of the two supports 41. The testing ends of the gap gauges 30 can respectively abut against the third testing part 24 and the fourth testing part 25 near the first positioning bracket 41. The side of one side abuts against the other side to detect the position of the two parts to be tested. Then, the gap gauge 30 is inserted into the second positioning hole 7, and the detection end of the gap gauge 30 can abut against the side of the seventh detection part 28 near the first positioning bracket 4 to detect the position of the seventh detection part 28. Finally, the surface difference gauge 29 is inserted into the six insertion holes 8 one by one, so that the detection end of the surface difference gauge 29 can accurately detect the position of the top surface of the first detection part 22, the second detection part 23, the third detection part 24, the fourth detection part 25, the fifth detection part 26 and the sixth detection part 27.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
