[0002] New energy batteries are usually installed in battery boxes, which usually include a box body and a box cover, with the box cover fitted on the box body. The box body needs to be tested for aperture and flatness to ensure product quality. Some inspection tools do not fix the box body during inspection, and only test the aperture without testing the flatness, resulting in low inspection efficiency.

[0003] For example, the battery pack lower case mounting hole position inspection fixture disclosed in Chinese patent application number CN201921687643.2 includes an inspection fixture bracket and an inspection fixture body installed on the inspection fixture bracket; the inspection fixture bracket constitutes the main structure of the inspection fixture, which is used for the installation and fixation of the inspection fixture body, and the inspection fixture body is used to detect whether the position of the battery lower case mounting hole is misaligned or offset. This type of inspection fixture cannot press the battery case tightly during inspection, and the case is prone to loosening. At the same time, the inspection fixture can only detect the aperture, but not the flatness, and the inspection efficiency is low. Utility Model Content

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] Please refer to Figures 1 to 6 As shown, it shows the specific structure of a preferred embodiment of the utility model, which is a box inspection tool.

[0030] When the box 18 is inspected, the first quick clamp 116 quickly fixes the box 18 on the positioning frame 11 to prevent the box 18 from moving. The first go-no-go gauge 110 is used to detect whether each aperture is qualified. The support column 19 supports the inner wall of the box 18 to prevent the box 18 from sinking. The second go-no-go gauge 120 is used to detect whether the top of the box 18 is flat. This box inspection fixture can not only detect each aperture, but also be used to detect flatness, with higher detection efficiency.

[0031] The present application provides a box inspection tool, including a workbench 10 and a positioning frame 11; the positioning frame 11 is arranged on the workbench 10; a positioning plate 13 is arranged on the inner side of a frame of the positioning frame 11; a plurality of positioning holes 14 are arranged on the positioning frame 11 and the positioning plate 13, and a first go-no-go gauge 110 can be inserted into the positioning hole 14; a plurality of support columns 19 are arranged in the positioning frame 11; a plurality of first quick clamps 116 are arranged on the outer side of the positioning frame 11, and the first quick clamps 116 can press the box 18 against the positioning frame 11; the detection beam 30 can be opened and closed on the upper side of the positioning frame 11, and the second go-no-go gauge 120 can be inserted into the gap between the detection beam 30 and the box 18. The shape of the positioning frame 11 of this embodiment is adapted to the shape of the box 18. When the box 18 is inspected: 1. The box 18 is placed on the positioning frame 11, and then the box 18 moves slightly toward the positioning plate 13, so that the inner wall of the box 18 and the positioning plate 13 are close together. 2. The first quick clamp 116 presses the box 18 against the positioning frame 11 to ensure that the box 18 does not loosen during the inspection, and then the inspection beam 30 is closed. 3. The first go / no-go gauge 110 is inserted into the positioning hole 14 to inspect each mounting hole of the box 18 (if it is loose, the hole is too large; if it cannot be inserted, the hole is too small). 4. The second go / no-go gauge 120 moves back and forth in the gap between the inspection beam 30 and the box 18 (if it encounters obstruction or the gap is too large, it is uneven) to detect whether the top of the box 18 is flat. The first quick clamp 116 and the second quick clamp 117 in this embodiment are preferably horizontal clamps. The mounting holes of the box 18 correspond to the positioning holes 14 one by one.

[0032] Preferably, a plurality of first positioning blocks 12 are provided on the outer side of the positioning frame 11, and the first positioning blocks 12 block the edge of the box 18. When the box 18 is placed in the positioning frame 11, the first positioning blocks 12 block the edge of the box 18, which can prevent the box 18 from shifting and ensure that the box 18 is aligned with the detected hole position.

[0033] Preferably, a first mounting seat 31 and a second mounting seat 32 are provided on the outer side of the positioning frame 11, and the first end of the detection beam 30 is hinged on the first mounting seat 31; the second quick clamp 117 is provided on the second mounting seat 32, and the detection beam 30 can be pressed against the second mounting seat 32. When the box 18 is loaded, the detection beam 30 is flipped up and opened; when the box 18 is loaded in place, the detection beam 30 can be closed downward. The first mounting seat 31 and the second mounting seat 32 suspend the detection beam 30, and the detection beam 30 obtains a sufficient height to match the height of the box 18 to achieve measurement.

[0034] Preferably, the first go / no-go gauge 110 includes a sleeve 111, a first detection head 113, and a second detection head 114. A limiting hole 112 is provided on the sleeve 111. Both the first detection head 113 and the second detection head 114 are provided with a limiting opening 115. A latch is inserted into the limiting hole 112 and is clamped in the limiting opening 115. The diameter of the first detection head 113 is smaller than the diameter of the second detection head 114. The first detection head 113 and the second detection head 114 have different sizes, and both sizes are within the error range of the hole of the box body 18, so the size of the installation hole can be well detected to ensure the correctness of the detection. The interior of the sleeve 111 is hollow, and the latch is inserted into the limiting hole 112 and is clamped in the limiting opening 115, so that the first detection head 113 and the second detection head 114 can be assembled, which is very simple and convenient.

[0035] Preferably, the second go / no-go gauge 120 has a curved first detection rod 121 and a second detection rod 122, wherein the diameter of the first detection rod 121 is smaller than the diameter of the second detection rod 122. The diameters of the first detection rod 121 and the second detection rod 122 are within the allowable error range of the flatness of the box body 18. The first detection rod 121 and the second detection rod 122 are used together to ensure the correctness of the detection and achieve a better detection effect.

[0036] Preferably, the second go / no-go gauge 120 is connected to a power source, and the detection beam 30 is conductive. If the box body 18 bulges, the gap between the box body 18 and the detection beam 30 will become smaller. At this time, the second go / no-go gauge 120 moves in the gap, and the second go / no-go gauge 120 and the detection beam 30 are conductive, which can more conveniently determine the flatness.

[0037] Preferably, a conductive spring pin is provided on the top of the support column 19, and the conductive spring pin can be pressed by the inner wall of the box body 18 to conduct. The elastic force of the conductive spring pin is very small, and the flat inner wall of the box body 18 can press it down. For example, if the inner wall of the box body 18 is uneven, some of the conductive spring pins will not be triggered, so it can be judged that the box body 18 at the position of the conductive spring pin is concave toward the outside. Therefore, in addition to the supporting function, the support column 19 can also detect the flatness of the inner wall of the box body 18, and the detection efficiency is higher.

[0038] Preferably, there are at least three detection beams 30, and the three detection beams 30 are distributed at equal intervals. The number and arrangement of the detection beams 30 are not unique and can be specifically set according to needs.

[0039] Preferably, the workbench 10 is arranged on a support frame, the support frame is provided with rollers 15 and handles 16, and a lifting ring 17 is arranged on the workbench 10. The support frame supports the workbench 10, and the rollers 15, handles 16, and lifting rings 17 facilitate the transfer of the box inspection fixture.

[0040] In summary, the design focus of the utility model is that its first quick clamp 116 can press the box body 18 against the positioning frame 11 to prevent the box body 18 from moving. After the box body 18 is fixed, the first go / no-go gauge 110 is inserted into each positioning hole 14 to detect whether each aperture is qualified. The second go / no-go gauge 120 moves back and forth in the gap between the detection beam 30 and the box body 18 to detect whether the top of the box body 18 is flat. The box body inspection fixture can not only prevent the box body 18 from loosening during inspection, but also detect the aperture and flatness, and its inspection efficiency is higher.
