The embodiments described below with reference to the drawings are exemplary and are intended to explain the application, and should not be understood as limiting the application.

[0031] As shown in Figures 1 to 7 , the embodiment provides a positioning tool for mounting an exhaust pipe 4 to a filler cap 5.

[0032] In the embodiment, in combination with Figure 1 and Figure 2 , the filler cap 5 is provided with an exhaust port 501 for exhaust, and the exhaust pipe 4 is mounted in the exhaust port 501 and communicates with the exhaust port 501.

[0033] In combination with Figures 1 to 4 , the positioning tool comprises a base 1, a positioning device 2 and a clamping device 3, the base 1 has a first direction x; the positioning device 2 comprises a first positioning block 21 and a second positioning block 22 which are arranged at intervals along the first direction x, and a first positioning interval is arranged between the first positioning block 21 and the second positioning block 22, the first positioning interval is used for positioning the filler cap 5.

[0034] In the embodiment, the first direction x is the length direction of the base 1. The first positioning block 21 and the second positioning block 22 can move relative to the base 1 along the first direction x, so that the first positioning interval between the first positioning block 21 and the second positioning block 22 can be adjusted to match filler caps 5 of different size specifications, thereby improving the versatility of the positioning device 2.

[0035] In addition, the positioning device 2 further comprises a first fixing member for fixing the first positioning block 21 and the second positioning block 22, the first fixing member being connected with the first positioning block 21 and the second positioning block 22, so that the first positioning block 21 and the second positioning block 22 can be fixed to the base 1 after moving, to ensure the positioning effect of the first positioning block 21 and the second positioning block 22 on the fuel filler cap 5.

[0036] For example, the first fixing member can be a bolt, a screw, etc.

[0037] Further, as shown in Figure 1 and Figure 6 , the clamping device 3 comprises a sliding part 31 and a clamping part 32 for clamping the exhaust pipe 4, the sliding part 31 being slidingly connected with the base 1, and the sliding part 31 reciprocally slides along the first direction x towards the first positioning interval, the clamping part 32 being rotationally connected with the sliding part 31, the clamping part 32 rotates relative to the sliding part 31, and the rotation center line of the clamping part 32 is parallel to the first direction x.

[0038] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the first positioning block 21 is farther away from the clamping device 3 along the first direction x relative to the second positioning block 22, and the exhaust port 501 of the fuel filler cap 5 is located on the side close to the second positioning block 22 along the first direction x, so that the exhaust port 501 of the fuel filler cap 5 is closer to the clamping device 3, to facilitate the installation of the exhaust pipe 4 in the exhaust port 501 of the fuel filler cap 5.

[0039] In this embodiment, as shown in Figure 1 and Figure 3 , the base 1 comprises a first bottom plate part 11 and a second bottom plate part 12, the first bottom plate part 11 being connected with the second bottom plate part 12, the positioning device 2 being connected with the first bottom plate part 11, and the sliding part 31 being slidingly connected with the second bottom plate part 12. Among them, the second bottom plate part 12 comprises a bottom plate body 121 and a sliding rail 122, the sliding rail 122 being connected with the bottom plate body 121, the bottom plate body 121 being connected with the first bottom plate part 11, and the sliding rail 122 being slidingly connected with the sliding part 31.

[0040] In the embodiment, when the exhaust pipe 4 needs to be installed in the exhaust port 501 of the oil filler cap 5, the oil filler cap 5 can be placed between the first positioning block 21 and the second positioning block 22, so that the oil filler cap 5 is positioned in the first positioning interval; then the clamping portion 32 clamps the exhaust pipe 4 to ensure the stability of the exhaust pipe 4 during installation; then the sliding portion 31 is driven to slide along the first direction x towards the first positioning interval, so as to drive the exhaust pipe 4 to slide to contact the exhaust port 501 of the oil filler cap 5; finally, while driving the clamping portion 32 to rotate relative to the sliding portion 31, the sliding portion 31 is continuously driven to slide towards the exhaust port 501 of the oil filler cap 5, so that the exhaust pipe 4 can rotate by a certain angle when entering the exhaust port 501 of the oil filler cap 5. Compared with the direct pressing installation mode, the rotating installation mode is beneficial to reduce the installation difficulty of the exhaust pipe 4, avoid the deformation of the exhaust port 501 of the oil filler cap 5 caused by the direct pressing of the exhaust pipe 4, and further avoid the problem that the exhaust pipe 4 is easy to fall out after installation.

[0041] In summary, the positioning tool can not only replace manual installation of the exhaust pipe 4, but also be beneficial to improve the installation efficiency, reduce the installation difficulty of the exhaust pipe 4, and avoid the problem that the exhaust pipe 4 is easy to fall out after installation.

[0042] As shown in Figure 1 and Figure 5 , the base 1 also has a second direction y intersecting the first direction x, and the positioning device 2 further includes a third positioning block 23, which is correspondingly arranged on one side of the first positioning interval along the second direction y; the third positioning block 23 is used to position the oil filler cap 5 along the second direction y.

[0043] In the embodiment, the second direction y is the width direction of the base 1. When the exhaust pipe 4 is installed in the exhaust port 501 of the oil filler cap 5, the oil filler cap 5 can be placed in the first positioning interval, and the third positioning block 23 is correspondingly arranged on one side of the oil filler cap 5 along the second direction y, so that the third positioning block 23 can position the oil filler cap 5 along the second direction y, so as to prevent the oil filler cap 5 from moving along the second direction y and avoid the misalignment of the exhaust pipe 4 and the exhaust port 501 of the oil filler cap 5.

[0044] As shown in Figure 1 and Figure 5 , the positioning device 2 further includes a fourth positioning block 24, which is oppositely arranged with the third positioning block 23 along the second direction y, and a second positioning interval is arranged between the third positioning block 23 and the fourth positioning block 24, which is used to position the oil filler cap 5 along the second direction y.

[0045] In the embodiment, when the exhaust pipe 4 is installed on the exhaust port 501 of the filler cap 5, the filler cap 5 can be placed in the second positioning interval between the third positioning block 23 and the fourth positioning block 24, so that the filler cap 5 cannot move in the second direction y, and the alignment of the exhaust pipe 4 and the exhaust port 501 of the filler cap 5 is avoided.

[0046] It should be understood that, since the first positioning interval and the second positioning interval are both used for positioning the filler cap 5, the first positioning interval and the second positioning interval partially overlap. Therefore, when the filler cap 5 is located in the first positioning interval, the filler cap 5 is also located in the second positioning interval.

[0047] In the embodiment, the third positioning block 23 and the fourth positioning block 24 can move relative to the first bottom plate part 11 along the second direction y, so that the second positioning interval between the third positioning block 23 and the fourth positioning block 24 can be adjusted to match filler caps 5 of different sizes, thereby improving the versatility of the positioning device 2.

[0048] In addition, the positioning device 2 further comprises a second fixing member for fixing the third positioning block 23 and the fourth positioning block 24. The second fixing member is connected with the third positioning block 23 and the fourth positioning block 24, so that the third positioning block 23 and the fourth positioning block 24 can be fixed to the first bottom plate part 11 of the base 1 after moving, to ensure the positioning effect of the third positioning block 23 and the fourth positioning block 24 on the filler cap 5.

[0049] For example, the second fixing member can be a bolt, a screw, etc.

[0050] In the embodiment, in combination with Figure 5 It is shown that the positioning tool further comprises a support rod 7 located in the first positioning area and the second positioning area and connected with the first bottom plate part 11. The support rod 7 is used for supporting the filler cap 5.

[0051] In combination with Figure 1 and Figure 2 It is shown that the filler cap 5 comprises a cover part 51 for covering the oil tank port and a connecting member 52 connected with the vehicle body. The connecting member 52 is connected with the cover part 51, and the exhaust port 501 is arranged on the cover part 51.

[0052] In combination with Figure 1 and Figure 5 It is shown that the maximum distance between the third positioning block 23 and the fourth positioning block 24 is greater than the length of the cover part 51 and less than the total length of the cover part 51 and the connecting member 52.

[0053] In the embodiment, in combination with Figure 1 It is shown that the length of the cover part 51 is m, the length of the connecting member 52 is n, and the total length of the cover part 51 and the connecting member 52 is m+n.

[0054] It should be understood that the maximum distance between the third positioning block 23 and the fourth positioning block 24 is the distance between the side of the third positioning block 23 close to the fourth positioning block 24 along the second direction y and the side of the fourth positioning block 24 close to the third positioning block 23 along the second direction y.

[0055] In the embodiment, the third positioning block 23 is located at one side of the cover body 51 along the second direction y, the fourth positioning block 24 is located at the other side of the cover body 51 along the second direction y, and the fourth positioning block 24 is located between the cover body 51 and the connecting piece 52, which not only can position the oil filler cap 5, but also can reduce the probability of damage of the oil filler cap 5.

[0056] In the embodiment, in combination with Figure 1 As shown in the figure, the connecting piece 52 is in an "arc structure", one end of the connecting piece 52 is connected with the cover body 51, and the other end of the connecting piece 52 is spaced apart from the cover body 51.

[0057] It should be understood that, since the fourth positioning block 24 is located between the cover body 51 and the connecting piece 52, when the oil filler cap 5 moves close to the third positioning block 23 along the second direction y, the fourth positioning block 24 can block the movement of the connecting piece 52 to position the oil filler cap 5; when the oil filler cap 5 moves away from the third positioning block 23 along the second direction y, the fourth positioning block 24 can block the movement of the cover body 51 to position the oil filler cap 5. Therefore, the fourth positioning block 24 can position the oil filler cap 5 without affecting the connection between the connecting piece 52 and the cover body 51, which is conducive to reducing the probability of damage of the oil filler cap 5.

[0058] In the embodiment, in combination with Figure 1 As shown in the figure, the third direction z intersects with the first direction x and the second direction y, and the third direction z is the height direction of the base 1.

[0059] In combination with Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown in the figures, the first positioning block 21, the second positioning block 22 and the third positioning block 23 each include a positioning surface c facing the first positioning interval, which is used to contact the cover body 51; the positioning surface c is a "stepped surface".

[0060] In combination with Figure 1 and Figure 7 As shown in the figures, the fourth positioning block 24 includes a positioning surface c facing away from the first positioning interval, which is used to contact the connecting piece 52; the positioning surface c is a "stepped surface".

[0061] In the embodiment, the first positioning block 21, the second positioning block 22, the third positioning block 23 and the fourth positioning block 24 are all "ladder structures", and each of the first positioning block 21, the second positioning block 22, the third positioning block 23 and the fourth positioning block 24 comprises a first ladder a and a second ladder b, and the first ladder a and the second ladder b have a height difference along the third direction z.

[0062] Further, the first ladder a comprises a first ladder bottom surface c1 and a first ladder side surface c2, and the first ladder bottom surface c1 is connected with the first ladder side surface c2; the second ladder b comprises a second ladder bottom surface c3 and a second ladder side surface c4, and the second ladder bottom surface c3 is connected with the second ladder side surface c4, and the second ladder side surface c4 is connected with the first ladder bottom surface c1; the first ladder bottom surface c1 and the second ladder bottom surface c3 have a height difference along the third direction z, and the first ladder side surface c2 and the second ladder side surface c4 have a height difference along the third direction z.

[0063] It should be understood that the first ladder bottom surface c1, the first ladder side surface c2, the second ladder bottom surface c3 and the second ladder side surface c4 are all "ladder surfaces", i.e. positioning surfaces c.

[0064] In the "ladder structure" of the first positioning block 21, the second positioning block 22 and the third positioning block 23, in the embodiment, the first ladder a is closer to the first positioning interval or the second positioning interval relative to the second ladder b, and the first ladder bottom surface c1 of the first ladder a is in contact with the cover body 51, so that the cover body 51 can be placed on the first positioning block 21, the second positioning block 22 and the third positioning block 23 to position the oil filler cap 5.

[0065] In other embodiments, the "ladder structure" can also comprise two or more ladders, and the corresponding "ladder surfaces" can be selected according to the size of the oil filler cap 5.

[0066] In the "ladder structure" of the fourth positioning block 24, in the embodiment, the first ladder a is farther away from the second positioning interval relative to the second ladder b, and the first ladder bottom surface c1 of the first ladder a is in contact with the connecting piece 52, so that the connecting piece 52 can be placed on the fourth positioning block 24 to position the oil filler cap 5.

[0067] In combination with FIGS. 1-4, Figure 2 and Figure 3 As shown in FIG. 5, the clamping part 32 comprises a rotating part 321 and a plurality of clamping parts 322, the plurality of clamping parts 322 are connected with the rotating part 321, a clamping interval 301 for clamping the exhaust pipe 4 is arranged between the plurality of clamping parts 322, and the rotating part 321 is connected with the sliding part 31.

[0068] In the embodiment, the plurality of clamping portions 322 are used to clamp the exhaust pipe 4, so that the exhaust pipe 4 is clamped in the clamping section 301, to ensure the stability of the exhaust pipe 4 during installation, and to avoid sliding of the exhaust pipe 4.

[0069] In the embodiment, the plurality of clamping portions 322 are used to clamp the exhaust pipe 4, so that the exhaust pipe 4 is clamped in the clamping section 301, to ensure the stability of the exhaust pipe 4 during installation, and to avoid sliding of the exhaust pipe 4. Figure 3 As shown in FIG. 1, the positioning tool further comprises a front pushing cylinder 8 connected with the sliding part 31, which is used to push the sliding part 31 to reciprocate along the first direction x towards the first positioning section, so that the exhaust pipe 4 can slide towards the direction of approaching or moving away from the filler cap 5, and then the exhaust pipe 4 can be installed in the exhaust port 501 of the filler cap 5.

[0070] It should be understood that when the exhaust pipe 4 slides towards the direction of approaching the filler cap 5, the exhaust pipe 4 is installed in the exhaust port 501 of the filler cap 5; when the exhaust pipe 4 slides towards the direction of moving away from the filler cap 5, the installation of the exhaust pipe 4 is completed, and the clamping device 3 returns to the original position. In addition, the stroke of the front pushing cylinder 8 can be adjusted according to the actual installation situation, which is beneficial to improve the compatibility of the positioning tool.

[0071] In the embodiment, the plurality of clamping portions 322 are used to clamp the exhaust pipe 4, so that the exhaust pipe 4 is clamped in the clamping section 301, to ensure the stability of the exhaust pipe 4 during installation, and to avoid sliding of the exhaust pipe 4. Figures 1 to 3 As shown in FIG. 1, the positioning tool further comprises a front pushing cylinder 8 connected with the sliding part 31, which is used to push the sliding part 31 to reciprocate along the first direction x towards the first positioning section, so that the exhaust pipe 4 can slide towards the direction of approaching or moving away from the filler cap 5, and then the exhaust pipe 4 can be installed in the exhaust port 501 of the filler cap 5.

[0072] For example, when the exhaust pipe 4 slides to contact the exhaust port 501 of the filler cap 5 and needs to be installed in the exhaust port 501, the rotary motor 9 can be started to rotate the exhaust pipe 4 while pushing the exhaust pipe 4.

[0073] In other embodiments, a rotary cam can be used to cooperate with a cam groove on the pushing shaft to realize the rotation of the exhaust pipe 4.

[0074] In the present embodiment, the plurality of gripping portions 322 includes a first gripping portion 322a and a second gripping portion 322b connected with the rotating portion 321, the first gripping portion 322a and the second gripping portion 322b are oppositely arranged along the third direction z. The first gripping portion 322a includes a first front matching surface matching with the surface of the exhaust pipe 4, the second gripping portion 322b includes a second front matching surface d matching with the surface of the exhaust pipe 4, the first front matching surface and the second front matching surface d are oppositely arranged along the third direction z, and the clamping interval 301 is located between the first front matching surface and the second front matching surface d, so that the exhaust pipe 4 is clamped in the clamping interval 301 between the first front matching surface and the second front matching surface d to ensure that the exhaust pipe 4 does not slide.

[0075] In combination Figure 2 and Figure 3 As shown in FIG. 5, the clamping portion 32 includes an elastic clamping piece portion 323 of "U-shaped structure", the elastic clamping piece portion 323 includes a first clamping piece portion 323a and a second clamping piece portion 323b, one end of the first clamping piece portion 323a is connected with one end of the second clamping piece portion 323b, the other end of the first clamping piece portion 323a is spaced apart from the other end of the second clamping piece portion 323b, and the spacing distance is less than the diameter of the exhaust pipe 4, and a clamping cavity 302 for positioning the exhaust pipe 4 is arranged between the first clamping piece portion 323a and the second clamping piece portion 323b.

[0076] In the present embodiment, the first clamping piece portion 323a is connected with the first gripping portion 322a, the second clamping piece portion 323b is connected with the second gripping portion 322b, and the opening of the elastic clamping piece portion 323 is arranged towards the second direction y.
