[0040] The utility model is described in detail below in conjunction with the accompanying drawings.

[0041] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0042] In the battery production process, the battery cover is often placed in the contoured groove of the tooling to achieve positioning, and then the battery cover is welded to the pole. However, the structure of this tooling is fixed, and different tooling needs to be configured for different battery covers. This will increase the production cost of the tooling on the first hand; on the second hand, the tooling needs to be changed as the battery production specifications change, reducing production efficiency. In response to such problems, the technical solution of this application is generated, and the following is combined with Figure 1 to Figure 5 To elaborate.

[0043] Example 1

[0044] The present application discloses a tool for a battery cover, which may include a mounting seat 10 and a positioning assembly 20. The mounting seat 10 is provided with a receiving cavity 11 for placing the battery cover, and at least part of the positioning assembly 20 is slidably disposed in the receiving cavity 11 to separate the receiving cavity 11 into a first cavity 111 and a second cavity 112 sequentially disposed in a sliding direction X of the positioning assembly 20. The sliding direction X here can be understood as the length direction of the receiving cavity 11.

[0045] When welding of the battery cover and the pole is required, the battery cover can be placed in the first cavity 111 or the second cavity 112, and the positioning assembly 20 can be slid against the battery cover to clamp and fix the battery cover, and then the battery cover and the pole can be welded in a fixed state.

[0046] It can be seen that the slidable setting of the positioning component 20 makes the first cavity 111 and the second cavity 112 both spatially variable cavities, and the sizes of the first cavity 111 and the second cavity 112 can be adjusted to adapt to the specifications of the clamped battery cover. In this way, on the first aspect, the tooling of the present application can be adapted to battery covers of various specifications, thereby improving the compatibility of the tooling and reducing production costs; on the second aspect, the tooling does not need to be changed as the battery production specifications change, so as to improve production efficiency.

[0047] Optionally, the positioning assembly 20 may include a positioning block 21 and a pressing plate 22, wherein at least a portion of the positioning block 21 may be slidably disposed in the accommodating cavity 11, such as the positioning block 21 being entirely disposed in the accommodating cavity 11, or a portion of the positioning block 21 being disposed in the accommodating cavity 11, and another portion being disposed outside the accommodating cavity 11, and the positioning block 21 being used to fix the battery cover, and taking the cover of a square battery as an example, the positioning block 21 may be configured as a rectangular slider, wherein the surface of the positioning block 21 in contact with the battery cover may be configured as a plane, so as to maintain a larger contact area with the battery cover and improve the clamping stability, and the surface of the positioning block 21 for sliding contact with the accommodating cavity 11 may also be configured as a plane, so as to maintain a larger contact area with the side of the accommodating cavity 11, improve the guiding effect during sliding, and prevent abnormal shaking. At least a portion of the pressing plate 22 may be located outside the accommodating cavity 11, such as the pressing plate 22 being entirely disposed outside the accommodating cavity 11, or a portion of the pressing plate 22 being disposed outside the accommodating cavity 11, and another portion extending into the accommodating cavity 11.

[0048] The mounting seat 10 may be provided with a first avoidance groove 12 that is connected to the bottom of the accommodating cavity 11. The first avoidance groove 12 is located between the positioning block 21 and the pressing plate 22, so that the positioning block 21 can be connected to the pressing plate 22. The provision of the first avoidance groove 12 can conveniently achieve the connection between the positioning block 21 and the pressing plate 22 without interfering with the sliding of the positioning assembly 20. The positioning block 21 and the pressing plate 22 both have a portion that is staggered from the first avoidance groove 12, so that a relatively stable structure is formed between the positioning assembly 20 and the mounting seat 10 to prevent mutual separation in actual work.

[0049] Optionally, the positioning block 21 and the pressing plate 22 can be fixedly connected to each other by welding, bonding, an integrated structure, etc. In the present application, the positioning block 21 is detachably connected to the pressing plate 22. In this way, in the first aspect, the mounting seat 10 and the positioning assembly 20 can be easily disassembled and assembled to facilitate the replacement and maintenance of the positioning assembly 20. In the second aspect, the accommodating cavity 11 after the positioning assembly 20 is removed can be adapted to battery covers of larger specifications and sizes, such as setting the length of the accommodating cavity 11 to 351.25 mm to adapt to battery covers of larger lengths. In other words, after the mounting seat 10 is assembled with the positioning assembly 20, any one of the first cavity 111 and the second cavity 112 formed, as well as the accommodating cavity 11 formed after the mounting seat 10 is disassembled from the positioning assembly 20, can be used for clamping the battery cover, further improving the compatibility of the tooling of the present application.

[0050] Optionally, the detachable connection between the positioning block 21 and the pressing plate 22 can be realized by plugging, clamping, etc. In the present application, the positioning assembly 20 can also include a clamping bolt 23, which can pass through a through hole provided on one of the positioning block 21 and the pressing plate 22 to be threadedly connected to a threaded hole provided on the other of the positioning block 21 and the pressing plate 22, for example, the positioning block 21 is provided with a through hole, and the pressing plate 22 is provided with a threaded hole corresponding to the through hole, or the positioning block 21 is provided with a threaded hole, and the pressing plate 22 is provided with a through hole corresponding to the threaded hole.

[0051] In specific application, one way is to loosen the clamping bolt 23 so that the positioning assembly 20 can slide freely in the accommodating cavity 11 to adjust the size of the first cavity 111 and the second cavity 112. When the positioning assembly 20 abuts against the clamped battery cover, the clamping bolt 23 is tightened so that the positioning block 21 and the pressure plate 22 clamp the solid part of the mounting seat 10 between the two, and then the positioning assembly 20 is locked and fixed in the current position, thereby completing the clamping and fixing of the battery cover. Another way is to remove the clamping bolt 23 so that the positioning block 21 and the pressure plate 22 are separated from each other, and then the positioning assembly 20 can be more conveniently removed from the mounting seat 10, so that the accommodating cavity 11 can clamp a battery cover with a larger specification. It can be seen that by rotating the clamping bolt 23, the positioning assembly 20 can be more conveniently controlled and disassembled, thereby improving the ease of use of the tooling of this application.

[0052] Optionally, in the positioning assembly 20, a plurality of clamping bolts 23 may be provided to improve the connection effect, or only one clamping bolt 23 may be provided to facilitate manipulation.

[0053] Optionally, the positioning block 21 may include a positioning portion 211 and a guide portion 212. The positioning portion 211 is slidably disposed in the accommodating cavity 11 and has a portion staggered from the first avoidance groove 12. The positioning portion 211 is used to adjust the size of the first cavity 111 and the second cavity 112 to adapt to the battery cover, and is used to cooperate with the pressure plate 22 to clamp the mounting seat 10 to lock the positioning assembly 20 in the current position. The guide portion 212 is located in the first avoidance groove 12 and faces the pressure plate 22. The guide portion 212 cooperates with the first avoidance groove 12 in the sliding direction X. Through the guiding effect of the guide portion 212, the positioning assembly 20 is prevented from deviating from the preset movement path, thereby improving the movement accuracy of the positioning assembly 20 along the sliding direction X.

[0054] Optionally, the pressing plate 22 may include a boss portion 221 and a clamping portion 222, wherein the boss portion 221 is located in the first avoidance groove 12 and faces the positioning block 21, and the boss portion 221 cooperates with the first avoidance groove 12 in a guiding manner along the sliding direction X, so that the boss portion 221 and the guide portion 212 jointly guide the positioning assembly 20, better prevent the positioning assembly 20 from deviating from the preset motion path, and further improve the motion accuracy of the positioning assembly 20 along the sliding direction X. The clamping portion 222 is disposed outside the accommodating cavity 11 and is located on the side of the boss portion 221 away from the positioning block 21. The clamping portion 222 has a portion staggered from the first avoidance groove 12, and the clamping portion 222 is used to cooperate with the positioning block 21 to clamp the mounting seat 10, so as to lock the positioning assembly 20 in the current position.

[0055] Optionally, the first avoidance groove 12 can be set as an oblong hole, and the cross-sections of the guide portion 212 and the boss portion 221 are both oblong to match the shape of the first avoidance groove 12. In this way, the positioning component 20 can avoid scratching the mounting seat 10 during the sliding process.

[0056] Optionally, the first avoidance groove 12, the guide portion 212 and the boss portion 221 satisfy:

[0057] 0.2mm≤T7-T8≤0.3mm; 0.2mm≤T7-T9≤0.3mm;

[0058] T7 is the width dimension of the first avoidance groove 12 , T8 is the width dimension of the guide portion 212 , and T9 is the width dimension of the boss portion 221 . The width directions of the first avoidance groove 12 , the guide portion 212 , and the boss portion 221 are all the first direction Y.

[0059] It can be known that the difference between T7-T8 mentioned above is the gap size between the first avoidance groove 12 and the guide portion 212, and the difference between T7-T9 is the gap size between the first avoidance groove 12 and the boss portion 221. If the gap size is too small, the positioning component 20 is prone to get stuck during sliding, and if the gap size is too large, the guiding effect between the positioning component 20 and the first avoidance groove 12 is affected. Therefore, the above-mentioned size control is performed to ensure smooth sliding and precise guiding between the positioning component 20 and the first avoidance groove 12.

[0060] Example 2

[0061] Based on the first embodiment, the present embodiment further defines the structure of the mounting base 10, which is specifically as follows:

[0062] The mounting base 10 may also be provided with a second avoidance groove 13, which is connected to the periphery of the accommodating cavity 11. In this way, when the operator stores or removes the battery cover plate from the accommodating cavity 11 by hand, the second avoidance groove 13 can avoid the operator's hand, further facilitating the use of the tooling of the present application.

[0063] Optionally, the accommodating cavity 11 and the second avoidance groove 13 may be connected in sequence along the sliding direction X, or the direction in which the accommodating cavity 11 and the second avoidance groove 13 are connected in sequence may intersect with the sliding direction X, such as being connected in sequence along the first direction Y, which will not be described in detail here.

[0064] Optionally, multiple second avoidance grooves 13 may be provided, wherein at least one second avoidance groove 13 is connected to the first cavity 111, and at least one second avoidance groove 13 is connected to the second cavity 112. In this way, whether the battery cover is placed in the first cavity 111 or the second cavity 112, it can be conveniently accessed through the second avoidance groove 13, thereby improving the convenience of the device of the present application.

[0065] Optionally, the second avoidance groove 13 satisfies:

[0066] 9mm≤T5≤11mm, for example, T5=9mm, 10mm, 11mm, etc.

[0067] 19mm≤L5≤21mm, for example, T5=19mm, 20mm, 21mm, etc.

[0068] Among them, T5 is the width dimension of the second avoidance groove 13, L5 is the length dimension of the second avoidance groove 13, the width direction of the second avoidance groove 13 is the first direction Y, and the length direction of the second avoidance groove 13 is the sliding direction X, so that it can be better matched with the operator's fingers and facilitate the avoidance of human fingers.

[0069] Optionally, the mounting seat 10 may further be provided with a third avoidance groove 14 , the accommodating cavity 11 has adjacent first inner side surface 11 a and second inner side surface 11 b , and the third avoidance groove 14 is located at the intersection of the first inner side surface 11 a and the second inner side surface 11 b .

[0070] Taking the cover of a square battery as an example, the first inner side surface 11a in the accommodating cavity 11 can be arranged in pairs along the sliding direction X to correspond to the first outer side surface of the battery cover, and the second inner side surface 11b can be arranged in pairs along the first direction Y to correspond to the second outer side surface of the battery cover. The first direction Y intersects with the sliding direction X. The first direction Y can be understood as the width direction of the accommodating cavity 11, and the sliding direction X can be understood as the length direction of the accommodating cavity 11. The opening of the third avoidance groove 14 realizes the cleaning of the root position of the accommodating cavity 11. The intersection of the first outer side surface and the second outer side surface is the edge of the battery cover. In this way, when the battery cover is placed in the accommodating cavity 11, the third avoidance groove 14 can avoid the edge position of the battery cover to prevent the root of the accommodating cavity 11 from squeezing and interfering with the edge of the battery cover, so that the first outer side surface of the battery cover and the first inner side surface 11a form a good contact, thereby ensuring the positioning accuracy of the battery cover.

[0071] Optionally, a plurality of accommodating cavities 11 may be provided, for example, a plurality of accommodating cavities 11 are arranged in sequence along the first direction Y, or a plurality of accommodating cavities 11 are arranged in sequence along the sliding direction X, or a plurality of accommodating cavities 11 are arranged in a row along the first direction Y, and a plurality of rows are arranged along the sliding direction X. In this way, the tooling of the present application can realize the clamping of a plurality of battery cover plates, thereby improving production efficiency.

[0072] Optionally, a plurality of accommodating cavities 11 are sequentially arranged along the first direction Y, and a partition 15 is formed between adjacent accommodating cavities 11, and the partition 15 and the accommodating cavities 11 satisfy:

[0073] 12≤M≤16, for example, M=12, 14, 16, etc., preferably M=14, wherein M is the ratio of the width dimension T4 of the accommodating cavity 11 to the width dimension T3 of the partition 15 .

[0074] Assuming that the width dimension of the accommodating cavity 11 is constant, if the above-mentioned ratio M is too small, the width dimension of the partition 15 will be too large, and the partition 15 will need to occupy too much space during specific use. If the ratio M is too large, the width dimension of the partition 15 will be too small, and the partition 15 will be easily deformed during specific use. Therefore, the dimension is controlled according to the above-mentioned ratio M so that the partition 15 has both structural stability and compactness.

[0075] Optionally, the partition 15 satisfies:

[0076] 4.5mm≤T3≤5.5mm, for example, T3=4.5mm, 5mm, 5.5mm, etc.

[0077] The accommodating chamber 11 satisfies:

[0078] 70mm≤T4≤70.5mm, for example, T4=70mm, 70.3mm, 70.5mm, etc.

[0079] Wherein, T3 is the width dimension of the partition 15, T4 is the width dimension of the accommodating cavity 11, and the width direction of the partition 15 and the width direction of the accommodating cavity 11 are both the first direction Y. In this way, the dimensions of the partition 15 and the accommodating cavity 11 can be better controlled to meet the use requirements of the tooling.

[0080] Optionally, the positioning block 21 satisfies:

[0081] 64.8mm≤T6≤65.2mm, for example, T4=64.8mm, 65mm, 65.2mm, etc.

[0082] Among them, T6 is the length dimension of the positioning block 21, and the length direction of the positioning block 21 is the first direction Y. If the length dimension of the positioning block 21 is too large, the gap between the positioning block 21 and the accommodating cavity 11 will be too small, and it is easy to get stuck during sliding. If the length dimension of the positioning block 21 is too small, it is not easy to position the battery cover. Therefore, the length dimension T6 of the positioning block 21 is controlled as described above, which can not only ensure that the positioning block 21 slides smoothly in the accommodating cavity 11, but also meet the positioning requirements of the battery cover.

[0083] Example 3

[0084] Based on Example 1, the present application can set a mounting base 10 including a top plate 101, a bottom plate 102, and a support plate 103 respectively connecting the top plate 101 and the bottom plate 102. The accommodating cavity 11 can be arranged on the side of the top plate 101 away from the bottom plate 102. In this way, the mounting base 10 forms a frame structure to achieve lightweight.

[0085] Optionally, multiple support plates 103 may be provided to improve the support capacity. The support plate 103 and the top plate 101, and the support plate 103 and the bottom plate 102 may be connected by bolts, riveting, welding, clamping, bonding, etc. to ensure the stability of the connection.

[0086] Optionally, both the support plate 103 and the bottom plate 102 may be provided with weight-reducing holes 104 to further improve the lightweight of the tooling of the present application.

[0087] Alternatively, if Figure 2 As shown,

[0088] The accommodating chamber 11 satisfies:

[0089] 9mm≤S4≤11mm, for example, S4=9mm, 10mm, 11mm; wherein S4 is the depth dimension of the accommodating cavity 11. If the depth of the accommodating cavity 11 is too shallow, the limiting effect of the battery cover is poor, while if the depth of the accommodating cavity 11 is too deep, it is difficult to take and place the battery cover, and the overall strength of the top plate 101 is affected. Therefore, the accommodating cavity 11 is set according to the above dimensions, which can take into account the limiting effect of the battery cover and convenient taking and placing, as well as ensure the strength of the top plate 101.

[0090] Optionally, the top plate 101 satisfies:

[0091] 9mm≤S5≤11mm, for example, S5=9mm, 10mm, 11mm; wherein S5 is the thickness dimension of the top plate 101 at the position corresponding to the accommodating cavity 11. If the thickness of the top plate 101 is too small, the overall strength is poor, and if the thickness of the top plate 101 is too large, materials are wasted and the weight of the tooling is increased. Therefore, the thickness of the top plate 101 is controlled according to the above dimensions to take into account both the overall strength and the lightweight of the tooling.

[0092] Alternatively, if Figure 4 As shown, the base plate 102 has first through grooves 1021 arranged in pairs in the sliding direction X, and second through grooves 1022 arranged in pairs in the first direction Y, and the area enclosed by the paired first through grooves 1021 and the paired second through grooves 1022 is provided with weight-reducing holes 104, and the size of the first through grooves 1021 is different from the size of the second through grooves 1022.

[0093] Specifically, the length dimension of the first through groove 1021 satisfies 54mm≤L1≤58mm, such as L1=54mm, 56mm, 58mm, wherein L1=56mm is preferred. The width dimension of the first through groove 1021 satisfies 5mm≤T1≤6mm, such as T1=5mm, 5.5mm, 6mm, wherein T1=5.5mm is preferred. The length dimension of the second through groove 1022 satisfies 98mm≤L2≤102mm, such as L2=98mm, 100mm, 102mm, wherein L2=100mm is preferred. The width dimension of the second through groove 1022 satisfies 5mm≤T2≤6mm, such as T2=5mm, 5.5mm, 6mm, wherein T2=5.5mm is preferred. The length direction of the first through groove 1021 is the first direction Y, and the length direction of the second through groove 1022 is the sliding direction X.

[0094] The support plates 103 are arranged in pairs in the first direction Y, and one of the paired support plates 103 is adjacent to one of the paired second through slots 1022 , and the other of the paired support plates 103 is adjacent to the other of the paired second through slots 1022 .

[0095] The provision of the first through groove 1021 and the second through groove 1022 can, on the one hand, remove more material of the base plate 102 to make the base plate 102 lighter, and secondly, can achieve fool-proofing. Specifically, due to the different sizes of the first through groove 1021 and the second through groove 1022, the support plate 103 can be prevented from being mistakenly installed on the side where the first through groove 1021 is located, thereby improving the assembly efficiency of the tooling of the present application.

[0096] Optionally, a pair of first through slots 1021 are provided, and a plurality of pairs of second through slots 1022 are provided, so as to further improve the foolproof effect and prevent the support plate 103 from being incorrectly installed.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
