[0027] A battery pack mounting hole pitch inspection tool, comprising an adjusting mechanism, two ends of the adjusting mechanism are provided with limit plates 10 perpendicular to the length direction of the adjusting mechanism, two sides of the adjusting mechanism and parallel to the length of the adjusting mechanism are provided with moving assemblies, two groups of limit frames 11 are arranged above the limit plates 10, both ends of the moving assemblies penetrate through the limit frames 11 and extend to the outside of the limit frames 11, a moving column 32 is slidingly inserted into the limit frames 11 on the moving assemblies, a fixing piece is arranged on the top of the moving column 32, and the moving state and the locking state of the moving assembly can be controlled in the process of the fixing piece moving up and down;

[0028] A first spring 33 is arranged on the surface of the moving column 32 and between the moving assembly and the bottom of the inner wall of the limit frame 11, a plurality of positioning pieces are arranged on the moving assembly and between the two groups of limit plates, the moving assembly is pressed to move downward to extrude the first spring 33, and the positioning pieces are used to control the movement of the battery pack mounting hole pitch inspection.

[0029] When the hole distance of the battery pack mounting hole needs to be inspected, according to the specification of the battery pack assembly drawing, the distance between the two sets of limiting plates 10 is adjusted by adjusting the mechanism, so that the two sets of limiting plates 10 are located on both sides of the battery pack, the inspection tool is quickly mounted or dismounted with the battery pack, and then the distance between the moving assembly and the positioning piece is adjusted according to the distance of the battery pack mounting hole. First, the distance between the two sets of moving assemblies is adjusted according to the distance of the mounting hole of the battery pack on different sides. The fixing piece at both ends of the moving assembly is pressed to make the fixing piece disengage from the limiting frame 11, so that the moving assembly can be switched from the locked state to the moving state, and the moving assembly moves inside the limiting frame 11. The distance between the two sets of moving assemblies is adjusted, and then the distance between the multiple positioning pieces in the length direction of the moving assembly is adjusted according to the distance between the multiple mounting holes on the same side of the battery pack assembly drawing, so that the positioning piece corresponds to the mounting hole of the battery pack assembly drawing one by one. When inspecting, first, the inspection tool is mounted on the battery pack to be detected through the limiting plate 10. Second, the moving assembly on both sides is pressed downward to extrude the first spring 33, so that the moving assembly drives the positioning pin 41 on the positioning piece to move downward. If the positioning pin 41 can be positioned in the mounting hole of the battery pack at the same time, it means that the hole center distance of the mounting hole is within the allowable tolerance range. Third, after the inspection is completed, the moving assembly is released, and under the restoring force of the first spring 33, it returns to the initial state. The positioning pin 41 disengages from the battery pack mounting hole, and then the inspection tool and the battery pack are dismounted for the next inspection. The inspection tool is simple and convenient to operate, short in time, can accurately check the workpiece, reduces the measurement error, improves the detection efficiency, and can be adjusted according to the specification of the battery pack.

[0030] In one embodiment, the adjusting mechanism includes an outer sleeve 20, a threaded rod 21 rotatably connected to both sides of the outer sleeve 20, a driven wheel 23 fixedly connected to one end of the threaded rod 21 inside the outer sleeve 20, a main drive wheel 22 meshingly connected between the two sets of driven wheels 23, a fixed rod provided on the top of the main drive wheel 22, the fixed rod penetrating through the outer sleeve 20 and extending to the outside of the outer sleeve 20, a threaded sleeve 24 threadedly sleeved on the surface of the threaded rod 21 and located outside the outer sleeve 20, and the threaded sleeve 24 being fixedly connected with the limiting plate 10. Rotating the main drive wheel 22 drives the threaded rod 21 to rotate through the driven wheel 23, which is used to control the distance between the two sets of limiting plates 10. When the distance between the limiting plates 10 needs to be adjusted, the fixed rod is driven to rotate, the fixed rod drives the main drive wheel 22 to rotate, the main drive wheel 22 drives the driven wheel 23 to rotate, the driven wheel 23 drives the threaded rod 21 to rotate, and the threaded rod moves the limiting plate 10 through the threaded sleeve 24. The distance between the two limiting plates 10 is adjusted to be suitable for battery packs of different sizes.

[0033] In order to avoid the problem that the moving assembly is inclined due to deviation of the positions of both ends of the moving assembly during movement, the limiting frame 11 is provided with a plurality of limiting holes 111 matched with the limiting column 34 on the top, and the positions of both ends of the moving assembly can be positioned through the limiting holes 111, so that the problem of deviation of the positions of both ends of the moving assembly is effectively avoided.

[0034] In order to avoid the problem that the limiting column 34 needs to be pressed again every time it passes through a limiting hole 111 during movement, and continuous movement cannot be performed, the efficiency of adjustment is reduced, the circumferential surface of the limiting column 34, which penetrates the limiting frame 11 and extends to the outside of the limiting frame 11, is provided with an annular groove 341, the limiting frame 11 is provided with a notch 112 matched with the annular groove 341 in size on the top and between two adjacent limiting holes 111, the limiting column 34 is pressed, so that the annular groove 341 on the limiting column 34 is aligned with the limiting hole 111, therefore, the moving assembly continuously moves through the notch 112 through the annular groove 341 on the limiting column 34, and the efficiency of adjustment is improved.

[0036] In order to facilitate the adjustment of the distance that the positioning pin 41 cooperates with the moving assembly to move downwardly, the positioning pin 41 and the positioning plate 40 are connected through threads, the distance between the bottom of the positioning pin 41 and the battery pack mounting hole can be adjusted, so that the distance between the bottom of the positioning pin 41 and the mounting hole is smaller than the distance that the moving assembly moves downwardly, so that the bottom of the positioning pin 41 can be inserted into the mounting hole of the battery pack in the distance that the moving assembly moves downwardly.
