The mounting hole position of the end plate is detected by the position of the positioning part 31, and the position of the longitudinal positioning mechanism 4 is pre-adjusted to further detect the width of the battery module. The detection tooling can simultaneously meet the detection of the mounting hole position of the battery module and the module width, thereby improving the detection efficiency.

[0048] As a preferred embodiment, the transverse moving mechanism 2 in this embodiment includes at least two first sliding components 21 and a moving part 22, wherein at least two first sliding components 21 are arranged on the base 1, and can move linearly along the length direction of the base 1, and have self-locking function; at least two moving parts 22 are arranged on the side of each first sliding component 21 away from the base 1, and the setting direction of the moving part 22 is perpendicular to the moving direction of the first sliding component 21, and at least two moving parts 22 are symmetrically arranged on the vertical plane of the midpoint of the width of the base 1.

[0049] It should be noted that the lateral moving mechanism 2 can move the moving part 22 along the length direction of the battery module, and can be adjusted according to the distance of the hole spacing on both sides of the length direction of the battery module, so that it can be suitable for end distance detection of battery modules of different sizes.

[0050] In this embodiment, there are four sliding components 21 . The four sliding components 21 are disposed at each corner of the base 1 , and the four sliding components 21 are distributed symmetrically about the center point of the base 1 .

[0051] It can be understood that each moving part 22 is disposed between two sliding components 21 on the same side, and the symmetrically disposed sliding components 21 connected by the moving part 22 can make the moving part 22 more stable during the movement process.

[0052] As a preferred embodiment, the longitudinal positioning mechanism 4 in this embodiment includes at least two second sliding components 41 and side blocks 42, wherein at least two second sliding components 41 are arranged on the base 1, and can move linearly along the width direction of the base 1, and have self-locking function; at least two side blocks 42 are arranged on one side of each second sliding component 41 away from the base 1, and at least two side blocks 42 are symmetrically arranged on the vertical plane of the midpoint of the length of the base 1.

[0053] It should be noted that there are two second sliding components 41, and the two second sliding components 41 are symmetrically arranged, so that the side block 42 can move linearly along the width direction of the battery module, and then the positions of the two side blocks 42 are pre-positioned at the specified position before detection, so that it can be suitable for width detection of battery modules of different sizes.

[0054] As a preferred embodiment, the first sliding component 21 and the second sliding component 41 in this embodiment both include a sliding opening 100, a sliding portion 210, a limiting portion 220 and a locking member 230, wherein the sliding opening 100 is opened on the base 1; the sliding portion 210 is slidably connected in the sliding opening 100; the limiting portion 220 is threadedly fixed to the corresponding sliding portion 210 through each fastener 23, and the limiting portion 220 abuts against the surface of the base 1, so as to lock the sliding portion 210 to the current position; the moving portion 22 and the side stopper 42 respectively fix the corresponding sliding portion 210 away from the side of the base 1.

[0055] It should be noted that when the position of the sliding assembly needs to be adjusted, the locking piece 230 is first loosened to release the abutment relationship between the limiting portion 220 and the base 1, and then the sliding portion 210 is pushed to slide to the desired position in the sliding mouth 100. When the sliding portion 210 reaches the desired position, the locking piece 230 is tightened to firmly fix the limiting portion 220 and the sliding portion 210 together, and the limiting portion 220 is tightly abutted against the base 1, and the sliding portion 210 is locked in the current position and cannot move anymore.

[0056] The outer contour of the sliding part 210 in this embodiment matches the inner contour of the sliding opening 100, and the side of the sliding part 210 away from the moving part 22 is flush with the surface of the base 1, ensuring that the sliding part 210 can move stably in the sliding opening 200, thereby increasing the structural stability.

[0058] It should be noted that before positioning, the initial position of the positioning portion 31 is first adjusted by sliding the second fastener 32 in the second window 200. When the positioning portion 31 is adjusted to a suitable position, the second fastener 32 is rotated to threadably connect and tighten with the positioning portion 31. During the tightening process, the gasket 33 will disperse the tightening force and provide a buffer. As the second fastener 32 is further tightened, the positioning portion 31 will be firmly fixed on the movable portion 22, and the spacing between the mounting holes on both sides of each end plate can be adjusted, thereby achieving end distance detection suitable for battery modules of different sizes.

[0059] The positioning portion 31 in this embodiment includes a connecting end 310 and a positioning segment 311, wherein the connecting end 310 is threadedly connected to the second fastener 32, and the connecting end 310 abuts against the adjacent surface of the movable portion 22; the positioning segment 311 is fixed to the end of the connecting end 310 away from the base 1, and the outer contour of the positioning segment 311 matches the inner contour of the end hole of the battery module.

[0060] It should be noted that the positioning section 311 can be inserted into the mounting hole of the end plate when positioning the mounting hole of the battery module, thereby preventing positioning deviation and shaking and ensuring positioning stability.

[0061] As a preferred embodiment, the side stopper 42 in this embodiment includes a plane section 421 and a vertical section 422, wherein the plane section 421 is fixed to the sliding portion 210 by bolts; the vertical section 422 fixes the plane section 421 to a side away from the sliding portion 210 and is perpendicular to the plane section 421, and the vertical section 422 abuts against the cable tie surface of the battery model.

[0062] The shape of the sliding opening 100 in this embodiment is a convex shape, and the sides of the two opposite sliding openings 100 away from the base 1 are connected to the outside.

[0063] It should be noted that, by designing the open-type sliding opening 100 , the first sliding assembly 21 and the second sliding assembly 41 can be quickly assembled and disassembled, and the two positioning parts 31 can be conveniently pre-positioned during installation.

[0064] Working principle:

[0065] First, a battery module of standard size is hoisted above the base 1. According to the position and width of the mounting hole of the battery module of standard size, the movable part 22 is moved to the corresponding longitudinal position of the mounting hole through the first sliding component 21, and then the two corresponding positioning parts 31 are adjusted to align the positioning part 31 with the mounting hole position, the positioning part 31 is inserted into the mounting hole, and the two opposite side blocks 42 are moved relative to each other to abut against the battery surface. At this time, the current positions of the positioning part 31, the movable part 22 and the side block 42 are locked, and the hole spacing and width of the subsequent battery module are measured using this position.
