[0033] Reference Figure 5 According to some embodiments of the present invention, the positioning slot 212 is arranged in an arc shape around the axis of the positioning sleeve 210. As a result, the arc-shaped positioning slot 212 allows the positioning pin 223 to be inserted into the positioning slot 212 from more positions, making it easier and simpler for the positioning pin 223 of the height compensation block 220 to be inserted into the positioning slot 212, making the height compensation block 220 easier and simpler to assemble and disassemble.

Therefore, the first magnet 410 and the second magnet 420 can cooperate with each other to attract each other, thereby fixing the height compensation block 220.

[0037] Reference Figure 1 、 Figure 4 and Figure 5 , when the mounting holes of the mounting module of the lower box need to be installed with rivet nuts for screwing bolts, usually the hole position of the inner hole of the rivet nut also needs to be detected. To this end, in some embodiments, the lower end surface of the first detection section 310 is connected to the second detection section 320, and the second detection section 320 is used to detect the inner hole of the rivet nut. Therefore, after completing the hole position detection of the mounting hole, the rivet nut can be installed on the mounting hole that has passed the subsequent detection. At this time, the heterogeneous mounting hole inspection fixture provided by the present invention can continue to be used to detect the hole position of the inner hole of the rivet nut. During the detection process, the second detection section 320 of the detection shaft 300 can be used to insert and detect the rivet nut. As a result, the mounting holes on the lower box of the battery and the rivet nuts installed in the mounting holes can use the heterogeneous mounting hole inspection fixture provided by the present invention to detect the hole positions, avoiding problems such as difficult and time-consuming operations when changing tooling processes, reducing trial production costs while improving product yields.

[0038] According to some embodiments of the present invention, an operating portion 330 is provided on the upper end of the detection shaft 300 to facilitate the staff to operate the detection shaft 300 to rise and fall. In addition, the operating portion 330 can also prevent the detection shaft 300 from completely entering the positioning sleeve 210.

[0039] Reference Figure 1 、 Figure 2 and Figure 4According to some embodiments of the present invention, the fixture 100 includes a main panel 100a and at least one sub-panel 100b, wherein at least one positioning hole 110 is provided on the main panel 100a, and at least one positioning hole 110 is provided on the sub-panel 100b, the sub-panel 100b is mounted on the main panel 100a, and the sub-panel 100b is located on the upper side or the lower side of the main panel 100a. Through the above arrangement, the lengths of the positioning sleeves 210 of each detection member can be configured to be the same, and through the arrangement of the sub-panel 100b, the height difference between the height positioning surface 221 of the height compensation block 220 located on the sub-panel 100b and the height positioning surface 221 of the height compensation block 220 on the main panel 100a is increased to meet the situation where the height position of some mounting holes on the battery lower case is larger than the height position of other mounting holes.

[0041] Of course, it is conceivable that, in other embodiments, the height difference between certain height positioning surfaces 221 can be increased by adjusting the installation height of the positioning sleeve 210 .

[0042] In some embodiments, the working principle of the non-planar mounting hole inspection fixture provided by the present invention is as follows:

[0043] In the first step, the main panel 100a and the auxiliary panel 100b are placed on the upper side of the corresponding mounting holes to be tested, so that each height positioning surface 221 is positioned at the corresponding mounting hole;

[0044] The second step is to insert the first detection section 310 of each detection shaft 300 into the corresponding mounting hole in sequence;

[0045] Step 3: If the first detection sections 310 of all detection shafts 300 can be inserted into the corresponding mounting holes, all mounting holes are correct. If the first detection sections 310 of one or more detection shafts 300 cannot be inserted into the corresponding mounting holes, remove the uninserted detection shafts 300 and visually check whether the corresponding mounting holes are offset.

[0046] Step 4: Record problem points and improve the process;

[0047] In the fifth step, after installing the rivet nut on the mounting hole, you can continue to use the non-planar mounting hole inspection fixture and use the second inspection section 320 of the inspection shaft 300 to inspect the hole position of the rivet nut. The measurement steps refer to the first to third steps.
