Detailed Implementation

[0024] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] Example 1: As Figures 1-3As shown in the figure, a detection tool for quickly detecting 7 groups of automobile batteries comprises a bottom plate 1, a positioning assembly 2, a reference positioning seat 3, a cover plate 31, a positioning sleeve 32, an elastic member 33 and a limiting sleeve 34. The positioning assembly 2 is connected with the bottom plate 1 and surrounds the edge of the bottom plate 1, and the positioning assembly 2 abuts against the bottom wall or the side wall of the battery 7. The reference positioning seat 3 is at least two, and the two reference positioning seats 3 are symmetrically arranged on the two sides of the bottom plate 1. The reference positioning seat 3 comprises that the cover plate 31 is connected with the bottom plate 1, and the cover plate 31 and the bottom plate 1 are provided with through holes in communication with each other. The positioning sleeve 32 is arranged in the through hole. The elastic member 33 is located between the positioning sleeve 32 and the cover plate 31. The limiting sleeve 34 is sleeved on the positioning sleeve 32, and the end of the positioning sleeve 32 away from the positioning assembly 2 is flush with the surface of the bottom plate 1.

[0026] In the implementation process, the elastic member 33 can adopt a spring. The bottom plate 1 can adopt carbon fiber material, which can reduce the weight of the detection tool while ensuring the overall strength, and facilitate the movement of the detection tool. The limiting sleeve 34 can adopt steel material. The outer wall of the positioning sleeve 32 can abut against the inner wall of the limiting sleeve 34, so that the limiting sleeve 34 plays a guiding function for the movement of the positioning sleeve 32.

[0027] In the invention, one of the two reference positioning seats 3 is used for X direction positioning, and the other is used for Y direction positioning, and the positioning assembly 2 is used for Z direction positioning. Through three coordinate synchronous positioning, the quick detection of whether the product is qualified is realized. Figure 5 As shown in the figure, after the detection tool is placed above the battery 7 through the positioning assembly 2, it is observed whether the positioning sleeve 32 can be accurately sleeved on the positioning reference pin on the battery 7, and it is observed that after the positioning sleeve 32 is sleeved on the positioning reference pin, the state of the positioning sleeve 32, if the end of the positioning sleeve 32 in the two reference positioning seats 3 is flush with the bottom plate 1, it means that the product is qualified, if the end of the positioning sleeve 32 in any one or all of the two reference positioning seats 3 protrudes from the surface of the bottom plate 1, it means that the product is unqualified. If the product is qualified, there is no interference between the positioning reference pin and the positioning sleeve 32, and the displacement of the positioning sleeve 32 does not change in the process of the positioning reference pin entering the positioning sleeve 32. If the product is unqualified, the positioning reference pin pushes the positioning sleeve 32 in the process of entering the positioning sleeve 32, causing the end of the positioning sleeve 32 to protrude from the surface of the bottom plate 1. When the detection tool is removed and the next battery 7 group is detected, even if the previous product is unqualified and the positioning sleeve 32 protrudes from the surface of the bottom plate 1, the positioning sleeve 32 can be reset under the action of the elastic member 33 and can be directly used for the next detection. As can be seen from the foregoing, the use and judgment process of the detection tool provided by the embodiment are simple and fast.

[0028] In order to facilitate the fixation of the elastic member 33, the embodiment 1 is improved, as shown in the figure. Figures 3-4As shown, in the embodiment, the positioning sleeve 32 comprises a large-diameter section 321 and a small-diameter section 322 which are in communication with each other, one end of the spring is connected with the end wall of the large-diameter section 321, the other end of the spring is connected with the cover plate 31, and the small-diameter section 322 is arranged in the through hole.

[0029] In the implementation process, Figure 4 In order to better show the relationship between the limiting sleeve 34 and the positioning sleeve 32, part of the outer shell 35 is hidden. The outer diameter of the section of the large-diameter section 321 is larger than that of the small-diameter section 322. After the positioning sleeve 32 is arranged in two sections with different outer diameters, as Figure 4 As shown, the spring can be sleeved on the small-diameter section 322, the large-diameter section 321 is used for connecting the top end of the spring, and the bottom end of the spring is connected with the cover plate 31.

[0030] Embodiment 3: In order to avoid that the large-diameter section 321 of the positioning sleeve 32 partially penetrates out of the limiting sleeve 34, resulting in inaccurate test results, the embodiment is improved on the basis of Embodiment 1, as Figure 3 As shown, in the embodiment, the inner wall of the limiting sleeve 34 is provided with a stopper 341, the positioning sleeve 32 is provided with a limiting groove 3211 matched with the stopper 341, and one end of the limiting groove 3211 away from the cover plate 31 is an open end.

[0031] In the implementation process, the stopper 341 and the limiting groove 3211 can be annular, and the stopper 341 is accommodated in the limiting groove 3211. As Figure 3 As shown, Figure 3 The open top end of the limiting groove 3211 facilitates the disassembly and assembly of the limiting sleeve 34, and also makes the positioning sleeve 32 have a downward movement degree.

[0032] Embodiment 4: In order to facilitate the installation and fixation of the limiting sleeve 34, in the embodiment, the reference positioning seat 3 further comprises an outer shell 35, the outer shell 35 is connected with the bottom plate 1, the outer shell 35 is provided with a stepped hole, and the limiting sleeve 34 is connected with the variable-diameter wall of the stepped hole.

[0033] In the implementation process, the inner wall of the stepped hole changes in diameter after passing through the variable-diameter wall in the process of extending along the axis thereof, the variable-diameter wall can be perpendicular to the central axis of the stepped hole, and the variable-diameter wall can be an annular wall. After the positioning sleeve 32 and the limiting sleeve 34 are accommodated in the outer shell 35, the outer shell 35 is fixed to the bottom plate 1, so that the positions of the two sleeves are fixed.

[0034] Embodiment 5: In order to realize the detection of the spatial position of the electrode and further reduce the weight of the gauge, the embodiment is improved on the basis of Embodiments 1-4, as Figures 1-2 and Figure 5As shown, in the embodiment, the bottom plate 1 is provided with a plurality of visual openings 11, and connecting ribs 12 are formed between adjacent visual openings 11; the gauge further comprises a first electrode detection piece 4, the first electrode detection piece 4 is connected with the connecting rib 12, the extension direction of the free end of the first electrode detection piece 4 is consistent with the positioning assembly 2, and the free end of the first electrode detection piece 4 is provided with first breaks 41, and any electrode of the battery 7 can be accommodated between the first breaks 41.

[0035] In the implementation process, the first electrode detection piece 4 can be made of ABS material, which can ensure insulation and prevent the product from being damaged. Since the electrode is located in the middle of the battery 7 group, the first electrode detection piece 4 for detecting the spatial position of the electrode is located in the middle of the bottom plate 1. If the bottom plate 1 is not provided with visual openings, the deviation can be observed through the visual openings 11 when the first electrode detection piece 4 fails to accurately reach the electrode detection position, so as to determine the error of the spatial position of the electrode. The width of the first break 41 can position the position of the electrode in the width direction of the battery 7, the length of the first break 41 can position the position of the electrode in the length direction of the battery 7, and the depth of the first break 41 can position the position of the electrode in the Z direction. For example, Figure 1 As shown, the first electrode detection piece 4 can be connected with the side of the bottom plate 1 away from the free end of the positioning assembly 2 through a transverse connecting plate, so that the gauge is convenient to move in the Figure 5 As shown, the mounting surface of the first electrode detection piece 4 is located at the upper part in the placement state, which is convenient for disassembly and assembly. Therefore, the connecting rib 12 provides a mounting position for the aforementioned connecting plate, and the provision of the visual opening 11 further reduces the weight of the gauge, so that the gauge is more convenient to move. The detection surface of the first electrode detection piece 4 can be detected by a go-no-go gauge with a specification of 9.5-10.5. The detection rods at both ends of the go-no-go gauge can be made of PEEK material to ensure insulation, and the handle is wrapped with plastic rubber to ensure insulation.

[0036] Embodiment 6: In order to realize detection of another electrode spatial position, improvement is made on the basis of embodiment 5, as shown in Figures 1-2 and Figure 5 As shown in the embodiment, the gauge further comprises a second electrode detection piece 5, the second electrode detection piece 5 is connected with the connecting rib 12, the extension direction of the free end of the second electrode detection piece 5 is consistent with the positioning assembly 2, the free end of the second electrode detection piece 5 is provided with second breaks 51, and another electrode of the battery 7 can be accommodated between the second breaks 51; and the length of the first break 41 is less than that of the second break 51.

[0037] In the implementation process, the second electrode detection piece 5 can be made of ABS material to ensure insulation and prevent damage to the product. The width of the second fracture 51 can position the electrode in the width direction of the battery 7, the length of the second fracture 51 can position the electrode in the length direction of the battery 7, and the depth of the second fracture 51 can position the electrode in the Z direction. As shown in Figure 1 The second electrode detection piece 5 can be connected to the side of the bottom plate 1 away from the free end of the positioning assembly 2 through a transverse connecting plate, so that the gauge is in the placement state shown, the mounting surface of the second electrode detection piece 5 is located at the upper part, and the disassembly and assembly are facilitated. Therefore, the connecting rib 12 provides a mounting position for the aforementioned connecting plate, and the opening of the visual port 11 further reduces the weight of the gauge, making the movement of the gauge more convenient. The detection surface of the second electrode detection piece 5 can be detected by a go-no-go gauge with a size of 9.35-9.65. The detection rods at both ends of the go-no-go gauge can be made of PEEK material to ensure insulation, and the handle is wrapped with plastic rubber insulation. Figure 5

[0038] Example 7: In order to better position the relative position of the gauge and the battery 7 during use, the embodiment is improved based on example 5, as shown in Figure 1 and Figure 5 In this embodiment, the positioning assembly 2 includes a coarse positioning piece 21, and each side of the bottom plate 1 is provided with at least one coarse positioning piece 21. The side wall of the coarse positioning piece 21 is used to abut the side wall of the battery 7, and the free end of the coarse positioning piece 21 includes an inclined wall 211 that gradually moves away from the center of the bottom plate 1 during extension away from the bottom plate 1.

[0039] In the implementation process, during the process of placing the gauge under the battery 7 to the detection position, the coarse positioning piece 21 first contacts the battery 7, and through preliminary positioning, the remaining positioning pieces can better reach the required position. As shown in Figure 5 The inclined wall 211 of the coarse positioning piece 21 provides a certain space for the coarse positioning piece 21 during the initial contact with the side wall of the battery 7, so that the battery 7 can better enter the space enclosed by the positioning assembly 2. Since the coarse positioning piece 21 is not used for Z-direction positioning, the bottom end of the coarse positioning piece 21 can not abut the bottom wall of the battery 7.

[0040] Example 8: In order to reduce the damage of the positioning piece for Z-direction positioning to the battery 7, the embodiment is improved based on example 7, as shown in Figure 5 ​As shown, in the embodiment, the positioning assembly 2 further comprises longitudinal positioning members 22, two of which are arranged at each corner of the bottom plate 1 and located at different sides of the corner of the bottom plate 1, and the free end of the longitudinal positioning member 22 is provided with a protrusion 221 facing one side of the bottom plate 1, which is used to abut against the side wall of the battery 7, and the end of the longitudinal positioning member 22 is used to abut against the bottom wall of the battery 7.

[0041] In the implementation process, the longitudinal positioning member 22 is used for positioning in the Z direction, and the coarse positioning member 21 has fixed the relative position of the gauge and the battery 7 in the horizontal plane. Since the side wall of the longitudinal positioning member 22 can not abut against the side wall of the battery 7, the longitudinal positioning member 22 can be provided with the protrusion 221 to make the side wall of the longitudinal positioning member 22 have a certain distance from the side wall of the battery 7. In addition, as shown in Figure 2 As shown, there is a certain distance between the bottom wall of the protrusion 221 and the bottom wall of the longitudinal positioning member 22, so that the inner wall of the end of the longitudinal positioning member 22 can limit the movement of the battery 7.

[0042] Embodiment 9: In order to avoid mutual interference between the coarse positioning member 21 and the tool for loading the battery 7, the embodiment 8 is improved, as shown in Figure 1 As shown, in the embodiment, the coarse positioning member 21 on the side of the reference positioning seat 3 comprises a first displacement member 212 and a second displacement member 213, the first displacement member 212 is located between the reference positioning seat 3 and the longitudinal positioning member 22, and the second displacement member 213 is located between the two longitudinal positioning members 22 and at the corner of the bottom plate 1, and the side wall of the free end of the second displacement member 213 is provided with a displacement opening 2131.

[0043] In the implementation process, as shown in Figure 1 As shown, the coarse positioning member 21 in the width direction of the gauge can be located at the middle of the long side of the gauge, and the coarse positioning member 21 in the length direction of the gauge cannot be located at the middle of the wide side due to the existence of the reference positioning seat 3, so the first displacement member 212 is arranged at a position deviating from the center of the wide side, and the second displacement member 213 opposite to it is arranged at the corner of the gauge in order to better position, but the tool for placing the battery 7 fixes the position of the battery 7 by limiting the movement of the four corners of the battery 7, so the second displacement member 213 is provided with the displacement opening 2131 in order to avoid the limiting arc plate.

[0044] Embodiment 10: As shown in Figures 1-2 As shown, the embodiment is improved on the basis of the embodiment 8, and in the embodiment, the gauge further comprises a pad 6, and the longitudinal positioning member 22 is connected with the bottom plate 1 through the pad 6.

[0045] In the implementation process, the cushion block 6 can be provided with multiple groups of mounting screw holes for adjusting the position of the longitudinal positioning member 22 in the horizontal plane. The thickness of the cushion block 6 can adjust the positioning data of the longitudinal positioning member 22 in the Z direction.

[0046] The above are only preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
