In some embodiments, referring to fig. 2 and 3, the first surface 311 conforms to the surface shape of the first location 11 and the third surface 321 conforms to the surface shape of the second location 21. That is, the first surface 311 conforms to the surface of the first position 11, and the third surface 321 conforms to the surface of the second position 21, so that when the first auxiliary tool 31 is connected to the front door panel 10 and the second auxiliary tool 32 is connected to the rear door panel 20, the first auxiliary tool 31 and the front door panel 10 are tightly adhered to each other, and the second auxiliary tool 32 and the rear door panel 20 are tightly adhered to each other, so that the probability of inaccurate detection results caused by the inclination of the first auxiliary tool 31 relative to the front door panel 10 and/or the inclination of the second auxiliary tool 32 relative to the rear door panel 20 can be reduced.

In some embodiments, as shown with reference to fig. 3 and 4, the fifth surface 314 of the first utensil 31 is provided with a first handle 315 and the sixth surface of the second utensil 32 is provided with a second handle 324. Here, the arrangement of the first handle 315 and the second handle 324 enables the connection between the first auxiliary tool 31 and the front door sheet metal 10 and the connection between the second auxiliary tool 32 and the rear door sheet metal 20 to be performed in a convenient manner by the detection personnel gripping the handles.

In some embodiments, referring to fig. 2, at least part of the first auxiliary tool 31 is a magnetic member, and at least part of the second auxiliary tool 32 is a magnetic member.

Specifically, at least part of the first auxiliary tool 31 is a magnetic member, that is, part of the first auxiliary tool 31 is a magnetic member, or all of the first auxiliary tools 31 are magnetic members, such as: the first auxiliary tool 31 is embedded with a magnetic member, for example: the first auxiliary tool 31 is a magnetic structure as a whole. At least part of the second auxiliary tool 32 is a magnetic member, that is, part of the second auxiliary tool 32 is a magnetic member, or all of the second auxiliary tools 32 are magnetic members, for example: the second auxiliary tool 32 has a magnetic member embedded therein, for example: the second auxiliary tool 32 is a magnetic structure as a whole.

In this embodiment, at least part of the first auxiliary tool 31 is a magnetic member, at least part of the second auxiliary tool 32 is a magnetic member, so that the first auxiliary tool 31 can be attached to the front door metal plate 10 after the first positioning pin 313 is inserted into the first mounting hole 12 of the front door metal plate 10, and the second auxiliary tool 32 can be attached to the rear door metal plate 20 after the second positioning pin 323 is inserted into the second mounting hole 22 of the rear door metal plate 20, thereby reducing the falling probability of the first auxiliary tool 31 and the second auxiliary tool 32 from the front door metal plate 10 and the rear door metal plate 20 respectively. In addition, at least part of the first auxiliary tool 31 is a magnetic member, and at least part of the second auxiliary tool 32 is a magnetic member, so that the first auxiliary tool 31 and the second auxiliary tool 32 can be adsorbed together, thereby reducing the probability of losing one of the first auxiliary tool 31 and the second auxiliary tool 32.

In some embodiments, referring to fig. 2 and 3, the first positioning pin 313 includes: the first positioning column 3131 and the second positioning column 3132, wherein two ends of the first positioning column 3131 are respectively connected with one ends of the first surface 311 and the second positioning column 3132, and the radial dimension of the first positioning column 3131 is larger than that of the second positioning column 3132; wherein the radial dimension of the first positioning column 3131 is equal to the radial dimension of the first mounting hole 12. Therefore, in the process of plugging the first positioning pin 313 into the first mounting hole 12, the radial dimension of the second positioning column 3132 is small, and the second positioning column 3132 firstly enters the first mounting hole 12, so that the positioning speed is faster and the positioning is more accurate when the first positioning pin 313 is plugged into the first mounting hole 12, meanwhile, the first positioning pin 313 can be plugged into and fixed to the first mounting hole 12 due to the fact that the radial dimension of the first positioning column 3131 is equal to the radial dimension of the first mounting hole 12, and the manufacturing material of the first positioning pin 313 can be reduced due to the fact that the radial dimension of the second positioning column 3132 is smaller than the radial dimension of the first mounting hole 12, so that the manufacturing cost of the first positioning pin 313 can be reduced.

In some embodiments, referring to fig. 2, the second positioning pin 323 includes: a third positioning post 3231 and a fourth positioning post 3232, wherein two ends of the third positioning post 3231 are respectively connected with one ends of the third surface 321 and the fourth positioning post 3232, and the radial dimension of the third positioning post 3231 is larger than that of the fourth positioning post 3232; wherein, the radial dimension of the third positioning post 3231 is equal to the radial dimension of the second mounting hole 22. Therefore, in the process of inserting the second positioning pin 323 into the second mounting hole 22, the radial dimension of the fourth positioning column 3232 is small, and the fourth positioning column 3232 firstly enters the second mounting hole 22, so that the positioning speed is faster and the positioning is more accurate when the second positioning pin 323 is inserted into the second mounting hole 22, meanwhile, the radial dimension of the third positioning column 3231 is equal to the radial dimension of the second mounting hole 22, so that the third positioning column 3231 can be inserted into and fixed to the second mounting hole 22, and the radial dimension of the fourth positioning column 3232 is smaller than the radial dimension of the second mounting hole 22, so that the manufacturing material of the second positioning pin 323 can be reduced, and the manufacturing cost of the second positioning pin 323 can be reduced.

In some embodiments, as shown in fig. 2 and 3, the surface of second positioning post 3132 distal from first positioning post 3131 is inclined relative to the axis of second positioning post 3132, and the surface of fourth positioning post 3232 distal from third positioning post 3231 is inclined relative to the axis of fourth positioning post 3232. That is, the end of the second positioning column 3132 far from the first positioning column 3131 and the end of the fourth positioning column 3232 far from the third positioning column 3231 are both in a sharpened state, so that the speed of inserting the first positioning pin 313 into the first mounting hole 12 and inserting the second positioning pin 323 into the second mounting hole 22 is faster, and the positioning is more accurate.

In some embodiments, the detection tool 30 may further include: the first connecting piece or the second connecting piece, the first connecting piece connects the first auxiliary tool 31 and the second auxiliary tool 32 respectively, when the second surface 312 of the first auxiliary tool 31 and the fourth surface 322 of the second auxiliary tool 32 are opposite, the length of the first connecting piece between the corresponding second surface 312 and the fourth surface 322 is equal to the preset length between the front door outer guard plate and the rear door outer guard plate; the second connecting piece is connected with the first auxiliary tool 31 and the second auxiliary tool 32 respectively, when the second surface 312 of the first auxiliary tool 31 is opposite to the fourth surface 322 of the second auxiliary tool 32, the length of the second connecting piece between the corresponding second surface 312 and the fourth surface 322 is larger than the preset length between the front door outer guard plate and the rear door outer guard plate, and the second connecting piece is provided with scales from one end connected with the first auxiliary tool 31 to one end connected with the second auxiliary tool 32.

Specifically, the first connecting piece connects the first auxiliary tool 31 and the second auxiliary tool 32 respectively, when the second surface 312 of the first auxiliary tool 31 and the fourth surface 322 of the second auxiliary tool 32 are opposite, the length of the first connecting piece between the corresponding second surface 312 and the fourth surface 322 is equal to the preset length between the front door outer guard and the rear door outer guard, therefore, when the first auxiliary tool 31 connects the front door sheet metal 10 and then connects the second auxiliary tool 32 with the rear door sheet metal 20, the assembly accuracy of the front door sheet metal 10 and/or the rear door sheet metal 20 can be determined to be problematic because the distance between the first connecting piece is short, and the second auxiliary tool 32 cannot be inserted into the second mounting hole 22 of the rear door sheet metal 20.

The second connecting piece is connected with the first auxiliary tool 31 and the second auxiliary tool 32 respectively, when the second surface 312 of the first auxiliary tool 31 and the fourth surface 322 of the second auxiliary tool 32 are opposite, the length of the second connecting piece corresponding to the second surface 312 and the fourth surface 322 is larger than the preset length between the front door outer guard plate and the rear door outer guard plate, and scales are arranged on the second connecting piece from one end connected with the first auxiliary tool 31 to one end connected with the second auxiliary tool 32, compared with the arrangement of the first connecting piece, the first auxiliary tool 31 of the embodiment can be inserted into the front door sheet metal 10 and the second auxiliary tool 32 can be inserted into the rear door sheet metal 20, and meanwhile, the distance between the inserted first auxiliary tool 31 and the second auxiliary tool 32 can be measured through the scales on the second connecting piece, so that the measured distance is compared with the preset gap, and accordingly, the assembly precision difference of the front door sheet metal 10 and/or the rear door sheet metal 20 can be confirmed, and accordingly, the front door sheet metal 10 and/or the rear door sheet metal 20 can be adjusted according to the obtained assembly precision difference.

In this embodiment, the implementation manners of the first connecting piece and the second connecting piece are different, and the obtained results are different, and may be selected according to actual requirements when implementing.

In some embodiments, referring to fig. 2 and 3, the number of first positioning pins 313 is at least 2; and/or the number of the second positioning pins 323 is at least 2.

Specifically, the number of the first positioning pins 313 is at least 2, and the arrangement of the 2 first positioning pins 313 may be consistent with the direction from the front door metal plate 10 to the back door metal plate 20, or may be consistent with the direction from the upper end of the front door metal plate 10 to the lower end of the front door metal plate 10, or may be other arrangement.
