[0014] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the new energy battery end plate inspection fixture includes: a square base plate 1, with a cuboid side block 2 on each of the left and right sides of the square base plate 1. The bottom of the side block 2 is flush with the bottom of the square base plate 1. The length of the two side blocks 2 is equal to the width of the square base plate 1, and the thickness of each side block 2 is equal to the sum of the thickness of the end plate 5 and the thickness of the square base plate 1. A cuboid end block 3 is provided on each of the front and rear sides of the square base plate 1. The bottom of the end block 3 is flush with the bottom of the square base plate 1. The length of the two end blocks 3 is equal to the sum of the length of the square base plate 1 and the width of the side block 2. The thickness of the end block 3 and the side block 2 is equal. An observation slot 4 for exposing the middle interlayer of the end plate 5 is provided in the middle of the upper surface of each of the two end blocks 3. The square groove formed by the two side blocks 2, the two end blocks 3, and the square base plate 1 is used to inspect the length, width, and thickness of the end plate 5. On the upper surface of the square base plate 1, there are elongated positioning posts 10 for detecting the elongated holes 6 on the back of the end plate 5 and circular positioning posts 11 for detecting the circular holes 7 on the back of the end plate 5. In this embodiment, there are two elongated holes 6 and four circular holes 7 on the end plate 5, two of which are large circular holes and two of which are small circular holes. At the four corners of the upper surface of the square base plate 1, there is a detection step 12 for detecting the arc-shaped groove 9 on the back of the end plate 5. Detection pin holes 17 are provided on the two side blocks 2. The detection pin holes 17 on the left side block 2 correspond one-to-one with the mounting holes 18 on the left side of the end plate 5, and the detection pin holes 17 on the right side block 2 correspond one-to-one with the mounting holes 18 on the right side of the end plate 5. In this embodiment, there are four mounting holes 18 on both the left and right sides of the end plate 5, and detection pins for inserting into the corresponding detection pin holes 17 and mounting holes 18 are also provided. It also includes: a plug gauge for detecting the bore diameter, and a square gauge for detecting the size of the square holes 8 on the left and right sides of the back of the end plate 5.

[0016] In this embodiment, each stop block is provided with a positioning through hole 14 and a countersunk through hole 13 at both ends. On the four sides of the square base plate 1, a positioning blind hole 15 and a threaded hole 16 are respectively provided at both ends. The diameters of the positioning blind hole 15 and the positioning through hole 14 are equal. The two positioning blind holes 15 on each side are aligned with the two positioning through holes 14 on the corresponding stop block, and the two threaded holes 16 on each side are aligned with the two countersunk through holes 13 on the corresponding stop block, respectively. A positioning pin is also provided for positioning the stop block by inserting it into the corresponding positioning through hole 14 and positioning blind hole 15, and a bolt is provided for fixing the stop block by passing through the countersunk through hole 13 and screwing it into the threaded hole 16. This configuration allows both side blocks 2 and end blocks 3 to be detachable. During installation, the blocks are placed tightly against the side of the corresponding square base plate 1, aligning the two blind positioning holes 15 on that side with the two through positioning holes 14 on the block to be installed. Two positioning pins are then inserted into the corresponding sets of through positioning holes 14 and blind positioning holes 15 to position the blocks. Next, the two threaded holes 16 on the side are aligned with the two countersunk holes 13 on the block. Two bolts are then screwed through the corresponding countersunk holes 13 into the corresponding threaded holes 16 to fix the blocks to the side of the square base plate 1. Both side blocks 2 and both end blocks 3 are installed using the above method.

[0017] To extend the service life of the gauge, a wear-resistant sleeve is installed in the inspection pin hole 17.

[0018] Both the elongated positioning post 10 and the round positioning post 11 have plugs at their bottoms, and plug holes are provided on the square base plate 1. The elongated positioning post 10 and the round positioning post 11 are fixed to the square base plate 1 by inserting the plugs into the corresponding plug holes. This design makes both the elongated positioning post 10 and the round positioning post 11 replaceable, allowing for timely replacement when they become worn.

[0019] During testing, the end plate 5 is placed into the square groove formed by the two side blocks 2, the two end blocks 3, and the square base plate 1. If the end plate 5 can be placed flat in the square groove and the upper surface of the end plate 5 is flush with the upper surface of the side blocks 2, it indicates that the length and width of the end plate 5, the position of each long hole 6, the position of each round hole 7, and the position of the four arc grooves 9 all meet the requirements. By observing the through groove 4, it can be seen whether each positioning pin is inserted in place. Then, the detection pins are inserted into the corresponding detection pin holes 17 and mounting holes 18 respectively. If the detection pins can be inserted in place each time, it indicates that the position of each mounting hole 18 meets the requirements. Then, the end plate 5 is taken out, and the inner diameter of each hole is checked by the plug gauge to see if it meets the requirements. Then, the length and width of the square hole 8 are checked by the go end and the stop end of the square gauge. When the go end of the square gauge can be put into the square hole 8, but the stop end of the square gauge cannot be put into the square hole 8, it indicates that the length and width of the square hole 8 meet the requirements.
