[0021] Beneficial effects:

[0022] The present invention provides a gauge for a battery case, wherein a base plate is provided with a reference positioning pin and a plurality of first elastic detection pins. When the battery case is installed in place on the base plate, a support block supports the lower end face of the battery case, and the reference positioning pin is inserted into the corresponding first reference positioning hole on the battery case, thereby achieving effective positioning of the battery case. The lower end face of the battery case is provided with a plurality of first mounting holes, and the plurality of first elastic detection pins are respectively provided with a plurality of first mounting holes. During the installation of the battery case on the support block on the substrate, if the position of the first mounting hole meets the requirements, the first pin of the first elastic detection pin will insert into the corresponding first mounting hole as the battery case gradually approaches the support block. At this time, the first elastic element is in an uncompressed state. However, for some first mounting holes that do not meet the positional accuracy requirements, they are not directly aligned with the corresponding first elastic detection pins, preventing the first pin from being inserted into the first mounting hole. As the battery case gradually approaches the support block, the first pin contacts the lower end face of the battery case. As the battery case continues to approach the support block, the lower end face of the battery case will push the first pin, causing the first elastic element to be compressed, indicating that the position of the first mounting hole at that location does not meet the accuracy requirements. By observing the state of multiple first elastic detection pins, operators can quickly detect the positional accuracy of multiple first mounting holes, which is convenient, saves manpower and resources, and has high measurement efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] This embodiment provides a gauge for inspecting battery boxes. (Refer to...) Figures 1 to 6 As shown, the inspection fixture for the battery box includes a base plate 1. The base plate 1 is provided with a support block 11, a reference positioning pin 12, and a plurality of first elastic detection pins 13. The battery box has a first reference positioning hole extending from its lower end face to its upper end face, and a plurality of first mounting holes are formed on its lower end face. The support block 11 supports the lower end face of the battery box. The reference positioning pin 12 passes through the first reference positioning hole. The plurality of first elastic detection pins 13 are correspondingly arranged with the plurality of first mounting holes. Each first elastic detection pin 13 includes a first base 131, a first pin head 132, and a first elastic element 133. The first base 131 is fixed to the base plate 1, and the first elastic element 133 is disposed between the first pin head 132 and the first base 131.

[0039] Specifically, when the battery case is supported on the support block 11 and the first pin 132 is aligned with the corresponding first mounting hole, the first pin 132 is inserted into the corresponding first mounting hole, and the first elastic member 133 is not compressed. When the battery case is supported on the support block 11 and the first pin 132 is not aligned with the corresponding first mounting hole, the first pin 132 cannot be inserted into the corresponding first mounting hole, the first pin 132 abuts against the lower end face of the battery case, and the first elastic member 133 is compressed. It can be understood that when the lower end face of the battery case is supported on the support block 11, the distance between the lower end face of the battery case and the first base 131 is a1, and the distance between the end of the first pin 132 and the first base 131 in its natural state is b1, where a1 < b1.

[0040] In this embodiment, when the battery box is installed on the substrate 1, the support block 11 supports the lower end face of the battery box, and the reference positioning pin 12 is inserted into the corresponding first reference positioning hole on the battery box to achieve effective positioning of the battery box. The lower end face of the battery box is provided with a plurality of first mounting holes, and a plurality of first elastic detection pins 13 are provided in a one-to-one correspondence with the plurality of first mounting holes. During the installation of the battery case on the support block 11 on the substrate 1, if the position of the first mounting hole meets the requirements, the first pin head 132 of the first elastic detection pin 13 will insert into the corresponding first mounting hole as the battery case gradually approaches the support block 11. At this time, the first elastic element 133 is in an uncompressed state. However, for some first mounting holes that do not meet the positional accuracy requirements, they are not directly aligned with the corresponding first elastic detection pin 13, making it impossible for the first pin head 132 to be inserted into the first mounting hole. As the battery case gradually approaches the support block 11, the first pin head 132 contacts the lower end face of the battery case. As the battery case continues to approach the support block 11, the lower end face of the battery case will push the first pin head 132 to move, causing the first elastic element 133 to be compressed, indicating that the position of the first mounting hole at that location does not meet the accuracy requirements. By observing the state of multiple first elastic detection pins 13, operators can quickly detect the positional accuracy of multiple first mounting holes, which is convenient, saves manpower and resources, and has high measurement efficiency.

[0041] In this embodiment, the fit between the first pin head 132 and the first mounting hole is a clearance fit, which ensures that the first elastic detection pin 13 can be smoothly inserted into the first mounting hole when facing the first mounting hole, thus preventing the first elastic element 133 from being compressed.

[0042] Specifically, the first elastic detection pin 13 also includes a ball head 135 and a sliding shaft 134. The sliding shaft 134 is located on the lower end face of the first pin head 132. The first elastic element 133 is sleeved on the sliding shaft 134. The first base 131 has a through hole. The end of the first sliding shaft 134 facing away from the first pin head 132 passes through the first through hole and is connected to the ball head 135. The diameter of the ball head 135 is larger than the diameter of the through hole. A limiting platform 136 is provided between the sliding shaft 134 and the first pin head 132. The upper end of the first elastic element 133 abuts against the limiting platform 136, and the lower end of the elastic element abuts against the first base 131. Specifically, when the first elastic detection pin 13 detects a first mounting hole that does not meet the positional accuracy requirements, the first pin head 132 contacts the lower end face of the battery case as the battery case gradually approaches the support block 11. As the battery case continues to approach the support block 11, the lower end face of the battery case pushes the first pin head 132, causing it to slide relative to the through hole at the end away from the battery case. This, in turn, causes the ball head 135 to move towards the end away from the case. By observing the position of the ball heads 135 of the multiple first elastic detection pins 13, the operator can quickly detect the positional accuracy of the multiple first mounting holes.

[0043] Specifically, the two ends of the first elastic member 133 abut against the limiting platform 136 and the first base 131 respectively, and the first elastic member 133 is sleeved on the sliding shaft 134. This arrangement ensures that the first elastic member 133 is reliably and stably installed, preventing the first elastic member 133 from accidentally popping out. Specifically, the diameter of the ball head 135 is larger than the diameter of the through hole. This arrangement allows the ball head 135 to limit the sliding shaft 134, preventing the sliding shaft 134 from protruding from the through hole.

[0044] In this embodiment, the inspection tool for the battery box also includes an upper cover 2, which is fastened to the base plate 1. The upper cover 2 is provided with a plurality of second elastic detection pins 21. The upper end face of the battery box is provided with a plurality of second mounting holes. The plurality of second elastic detection pins 21 are arranged in a one-to-one correspondence with the plurality of second mounting holes. The second elastic detection pin 21 includes a second base 211, a second pin head 212, and a second elastic member. The second base 211 is fixed on the upper cover 2, and the second elastic member is disposed between the second pin head 212 and the second base 211.

[0045] Specifically, when the battery case is supported on the support block 11, the top cover 2 is fastened to the base plate 1, and the second pin 212 is aligned with the corresponding second mounting hole, the second pin 212 is inserted into the corresponding second mounting hole, and the second elastic member is not compressed. When the battery case is supported on the support block 11, the top cover 2 is fastened to the base plate 1, and the second pin 212 is not aligned with the corresponding second mounting hole, the second pin 212 cannot be inserted into the corresponding second mounting hole, the second pin 212 abuts against the lower end face of the battery case, and the second elastic member is compressed. It can be understood that when the lower end face of the battery case is supported on the support block 11 and the top cover 2 is fastened to the base plate 1, the distance between the upper end face of the battery case and the second base 211 is a2, and the distance between the end of the second pin 212 and the second base 211 in the natural state is b2, and a2 and b2 satisfy the condition: a2 < b2.

[0046] In this embodiment, the upper surface of the battery housing is provided with multiple second mounting holes, and multiple second elastic detection pins 21 are correspondingly arranged with the multiple second mounting holes. During the process of the upper cover 2 and the substrate 1 being fastened together, if the position of the second mounting hole meets the requirements, the second pin head 212 of the second elastic detection pin 21 is inserted into the corresponding second mounting hole as the upper cover 2 gradually approaches the battery housing. At this time, the second elastic element is in an uncompressed state. However, for some second mounting holes that do not meet the positional accuracy requirements, they are not directly aligned with the corresponding second elastic detection pin 21, so that the second pin head 212 cannot be inserted into the second mounting hole. The second pin head 212 contacts the lower surface of the battery housing as the upper cover 2 gradually approaches the battery housing. As the upper cover 2 continues to approach the substrate 1, that is, as the upper cover 2 continues to approach the battery housing, the upper surface of the battery housing will push the second pin head 212 to move, causing the second elastic element to be compressed, indicating that the position of the second mounting hole at this position does not meet the accuracy requirements. Operators can quickly detect the positional accuracy of multiple second mounting holes by observing the status of multiple second elastic detection pins 21. The operation is convenient, saves manpower and material resources, and has high measurement efficiency.

[0047] In this embodiment, the fit between the second pin 212 and the second mounting hole is a clearance fit, which ensures that the second elastic detection pin 21 can be smoothly inserted into the second mounting hole when it is facing the second mounting hole, thus preventing the second elastic element from being compressed.

[0048] The detailed structure of the second elastic detection pin 21 can be set to be the same as that of the first elastic detection pin 13, which will not be elaborated on here.

[0049] In this embodiment, both the first elastic element 133 and the second elastic element are configured as springs.

[0050] In this embodiment, the overall outline of the battery box is set as a cube or cuboid. Multiple support blocks 11 are provided. The multiple support blocks 11 are arranged at intervals on the substrate 1 and together form a rectangular support frame structure. The multiple support blocks 11 are used to jointly support the four edges of the lower end face of the battery box.

[0051] Optionally, the first base 131 of the reference positioning pin 12 and the first elastic detection pin 13 can be directly disposed on the base plate 1 or disposed on the support block 11.

[0052] In this embodiment, a first contour detection block 14 is provided on the substrate 1, and a second contour detection block 22 is provided on the upper cover 2. A first detection gap is formed between the first contour detection block 14 and the side end face corresponding to the battery box, and a second detection gap is formed between the second contour detection block 22 and the side end face corresponding to the battery box. Specifically, when the battery box is installed in place on the substrate 1, the positional accuracy of the side end face of the battery box can be detected by using a standard plunger to measure the thickness of the first and second detection gaps.

[0053] In this embodiment, the substrate 1 is provided with a bushing detection pin 15, and the battery box is provided with a mounting bushing. The mounting bushing has a bushing hole, and the bushing detection pin 15 is used to pass through the bushing hole. Specifically, when the battery box is installed on the support block 11 on the substrate 1, if the bushing hole position meets the requirements, the bushing detection pin 15 will be inserted into the corresponding bushing hole as the battery box gradually approaches the support block 11. However, for some bushing holes that do not meet the positional accuracy requirements, they are not directly aligned with the corresponding bushing detection pin 15, so that the bushing detection pin 15 cannot be inserted into the bushing hole, thereby enabling rapid detection of the positional accuracy of multiple bushing holes.

[0054] Furthermore, the upper cover 2 has a detection positioning hole 231 corresponding to the bushing detection pin 15. When the upper cover 2 is fastened onto the substrate 1, the bushing detection pin 15 passes through the corresponding detection positioning hole 231. Specifically, a first positioning head 23 is provided on the edge of the upper cover 2, and the detection positioning hole 231 is formed on the first positioning head 23. Specifically, the insertion and engagement between the bushing detection pin 15 and the detection positioning hole 231 can also ensure the reliability and effectiveness of the positioning between the upper cover 2 and the substrate 1.

[0055] Optionally, in this embodiment, eight bushing detection pins 15 and detection positioning holes 231 are provided in a one-to-one correspondence.

[0056] Furthermore, the upper cover 2 has a second reference positioning hole 241 corresponding to the reference positioning pin 12. When the upper cover 2 is fastened onto the substrate 1, the reference positioning pin 12 passes through the corresponding second reference positioning hole 241. Specifically, a second positioning head 24 is provided on the edge of the upper cover 2, and the second reference positioning hole 241 is formed on the second positioning head 24. Specifically, the insertion and engagement between the reference positioning pin 12 and the second reference positioning hole 241 can further ensure the reliability and effectiveness of the positioning between the upper cover 2 and the substrate 1.

[0057] Optionally, two reference positioning pins 12 are provided, each corresponding to a second reference positioning hole 241. One of the reference positioning pins 12 has an end section with a waist-shaped structure.

[0058] In this embodiment, a reference positioning block 16 protrudes from the support block 11, and the lower end face of the battery case is supported on the reference positioning block 16. A third detection gap is formed between the lower end face of the battery case and the upper end face of the support block 11. Specifically, when the battery case is installed on the substrate 1, the support block 11 supports the lower end face of the battery case, and at this time, a third detection gap is formed between the lower end face of the battery case and the upper end face of the support block 11. The thickness of the third detection gap is detected by the reference positioning block 16, thereby realizing the positional accuracy detection of the lower end face of the battery case.

[0059] Specifically, the upper surface of the substrate 1 is a support end surface 101, and the support block 11, the reference positioning pin 12, the first elastic detection pin 13, and the bushing detection pin 15 are all disposed on the support end surface 101. A coordinate scale 102 is provided on the support end surface 101. Specifically, the coordinate scale 102 includes multiple horizontal and vertically intersecting horizontal and vertical coordinate lines, and the ends of the horizontal and vertical coordinate lines are respectively provided with scale values. The coordinate scale 102 enables the positioning of the battery box during installation, and the position of the battery box can be adjusted according to the coordinate scale 102 in real time, allowing for faster and more accurate installation of the battery box.

[0060] In this embodiment, a first docking positioning block 17 is provided on the substrate 1, and a second docking positioning block 26 is correspondingly provided on the upper cover 2. When the upper cover 2 is engaged with the substrate 1, the second docking positioning block 26 is supported on the corresponding first docking positioning block 17. Specifically, multiple first docking positioning blocks 17 and second docking positioning blocks 26 are provided in a one-to-one correspondence; in this embodiment, eight are provided.

[0061] Furthermore, the first docking positioning block 17 and the corresponding second docking positioning block 26 are fixed together by a fastener. Specifically, the first docking positioning block 17 has a first fixing hole 171, and the second docking positioning block 26 has a second fixing hole 261. The fastener passes through the first fixing hole 171 and the second fixing hole 261, and fixes the first fixing hole 171 and the second fixing hole 261. Optionally, the fastener is a screw, and both the first fixing hole 171 and the second fixing hole 261 can be threaded holes, with the screw threadedly connected to both the first fixing hole 171 and the second fixing hole 261.

[0062] Optionally, the fastener can be a bolt assembly. The bolt assembly includes a bolt and a nut. In this case, the first fixing hole 171 and the second fixing hole 261 do not need to be threaded holes. After the bolt passes through the first fixing hole 171 and the second fixing hole 261, it is threadedly connected to the nut, which can also achieve effective fixing between the first mating positioning block 17 and the corresponding second mating positioning block 26.

[0063] In this embodiment, the upper cover 2 is also provided with a handle 27. The handle 27 is provided for the operator to grasp the upper cover 2.

[0064] In this embodiment, a base support 3 is also included. The base plate 1 is fixed on the base support 3. A forklift slot 31 is provided on the side end of the base support 3, and multiple swivel casters 32 are provided on the lower end of the base support 3. Specifically, the base support 3 is provided to reliably and effectively support the base plate 1. The forklift slot 31 on the base support 3 is used to connect with the forks of a forklift, enabling rapid transport of the base support 3. The swivel casters 32 are provided to enable effective movement of the base support 3, facilitating short-distance flexible movement of the entire fixture.

[0065] Optionally, the substrate 1 and the base support 3 can be fixed by welding.

The lifting mechanism 4 includes a support frame 41, a lifting frame 42, and a lifting drive component 43. The lifting frame 42 is mounted on the support frame 41 and located above the base plate 1. The lifting frame 42 is provided with a hook 421 for lifting the top cover 2. The lifting drive component 43 is used to control the lifting frame 42 to rise and fall relative to the support frame 41. By setting up the lifting structure, the lifting and automatic raising and lowering of the top cover 2 can be realized, improving the accuracy and reliability of the movement of the top cover 2 and reducing manpower consumption. Specifically, the top cover 2 is provided with multiple first lifting lugs 25, and lifting chains are threaded through the multiple first lifting lugs 25. The hook 421 hooks the lifting chains to realize the overall lifting of the top cover 2.
