Often, a changeover process is required before another battery model can be produced. However, the tooling and fixtures used in the changeover phase require a lengthy process from purchase to commissioning, causing prolonged production line downtime and severely impacting battery production capacity. Furthermore, the storage and maintenance of the tooling and fixtures removed during the changeover process incurs costs, resulting in high overall expenses. Utility Model Content

[0005] An embodiment of this utility model provides a battery clamp, comprising:

[0006] Base, for holding the battery; and,

[0007] At least two clamping devices are provided for clamping the battery from different sides; wherein at least one of the clamping devices includes a lead screw and a clamping member, the lead screw being tractively connected to the clamping member, and rotation of the lead screw driving the clamping member to move along the extension direction of the lead screw, so that the clamping member presses the battery supported on the base.

[0008] In one embodiment, the at least one clamping device further includes a driving member, the lead screw being tractively connected to the driving member such that rotation of the lead screw can drive the driving member to move along the extension direction of the lead screw, and the driving end of the driving member being connected to the clamping member to drive the clamping member to move along the extension direction of the lead screw.

[0010] In one embodiment, the base includes:

[0011] Mounting plate, wherein the mounting plate has the through hole; and,

[0012] At least two limiting plates are provided, which are inserted into the through hole. The abutting part of each clamping device is disposed opposite to at least one of the limiting plates. The abutting part and the oppositely disposed limiting plate are used to jointly clamp the battery supported on the base.

[0013] In one embodiment, the clamping device includes a first clamping device and a second clamping device. Both the first clamping device and the second clamping device include the lead screw and the clamping member. The lead screw is throttledly connected to the clamping member.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0038] Reference Figures 1 to 3 This utility model provides a battery clamp 1, including: a base 11 and at least two clamping devices 12; the base 11 is used to support a battery; the at least two clamping devices 12 are used to clamp the battery from different sides; wherein, at least one clamping device 12 includes a lead screw 121 and a clamping member 122, the lead screw 121 and the clamping member 122 are throttle connected, and the rotation of the lead screw 121 can drive the clamping member 122 to move along the extension direction H1 of the lead screw, so that the clamping member 122 presses the battery supported on the base 11.

[0039] The base 11 serves a load-bearing function, providing a stable platform for the battery and facilitating the installation of the clamping device 12. This allows the battery to be held securely by the clamping device 12, enabling various battery-related operations such as testing, assembly, and welding to be performed. The base 11 can be made of metal or alloy materials, and its dimensions can be set according to actual needs; this application does not impose any limitations on this.

[0040] The function of at least two clamping devices 12 is to clamp the battery from different sides, ensuring that the battery is firmly fixed in the fixture and will not loosen or shift, thereby meeting the battery fixation requirements of various processes. At least one clamping device 12 may include a lead screw 121 and a clamping member 122, wherein the lead screw 121 and the clamping member 122 are connected by a threaded connection or other means to achieve transmission, so that when the lead screw 121 rotates, the clamping member 122 moves linearly along the extension direction H1 of the lead screw. For example, it can be configured such that when the lead screw 121 rotates clockwise, the clamping member 122 moves towards the battery; when the lead screw 121 rotates counterclockwise, the clamping member 122 moves away from the battery. In this way, the clamping and releasing operations of the battery are achieved. It is understood that other clamping devices 12 may adopt the same structure, or may use other methods to clamp the battery, such as applying pressure to the clamping structure through a hydraulic pump, elastic elements, or other structures to clamp the battery. In this embodiment, multiple clamping devices 12 clamp the battery from different sides, thereby constraining the battery in all directions and improving the stability of the battery in the clamp.

[0041] In some alternative embodiments, there are two clamping devices 12, which are arranged opposite to each other to clamp the opposite sides of the battery. In this case, the battery can be fixed in the horizontal direction by the clamping devices 12 alone.

[0042] In some alternative embodiments, there are two clamping devices 12, and the two clamping devices 12 clamp the adjacent sides of the battery respectively. In this case, other limiting structures, such as limiting posts, can be set on the base 11 to cooperate with the clamping devices 12 to fix the battery.

[0043] In embodiments of this utility model, by providing at least two clamping devices 12, and at least one clamping device 12 including a lead screw 121 and a clamping member 122, the user can change the position of the clamping member 122 by rotating the lead screw 121. For batteries of different sizes, only the rotation amount of the lead screw 121 needs to be adjusted accordingly to ensure that the clamping member 122 accurately contacts and presses the battery, thereby adapting to the clamping requirements in the length or width direction of batteries of different sizes. There is no need to design different clamps specifically for each battery size, greatly improving the versatility and efficiency of the battery clamp 1 and reducing production costs. Compared to other electric or pneumatic drive structures, the combination of the lead screw 121 and the clamping member 122 occupies less space, and by increasing the length of the lead screw 121, the clamping member 122 can move within a wider range, allowing the battery clamp 1 to clamp more types of batteries, further improving the adaptability and practicality of the battery clamp 1.

[0044] In one embodiment, reference is made to Figure 3At least one clamping device 12 further includes a driving member 123, and a lead screw 121 is connected to the driving member 123 so that the rotation of the lead screw 121 can drive the driving member 123 to move along the extension direction H1 of the lead screw. The driving end of the driving member 123 is connected to the clamping member 122 to drive the clamping member 122 to move along the extension direction H1 of the lead screw.

[0045] In practical use, if it is necessary to replace the battery with a different size, first rotate the lead screw 121, causing the drive component 123 and the clamping component 122 to move back and forth under the action of the lead screw 121. At this time, the drive component 123 and the clamping component 122 have a relatively long range of movement, which can be used for a wider range of battery types. After the drive component 123 and the clamping component 122 have moved to the appropriate position, the drive component 123 can be controlled to drive the clamping component 122 to move further, completing the fine adjustment of the position of the clamping component 122. Understandably, if the size of the battery being replaced is small, the position adjustment of the clamping component 122 can be completed using only the lead screw 121 or the drive component 123.

[0046] In some alternative embodiments, the drive element 123 is a cylinder, and the drive end of the cylinder can drive the clamping element 122 to reciprocate, thereby clamping the battery. The cylinder is simple to control, easy to install on the base 11, and the movement provided by the cylinder is smooth, which can reduce the probability of vibration during clamping and protect the battery from damage.

[0047] In this embodiment, the cooperation between the lead screw 121 and the drive component 123 enables precise control of the movement of the clamping component 122, making the positioning of the clamping component 122 more accurate and meeting the requirements of high-precision operation. Furthermore, small-range dimensional adjustments can be completed through the drive component 123, reducing the operational burden on the operator and improving the adjustment efficiency of the fixture.

[0048] In one embodiment, reference is made to Figure 1 and Figure 4 The base 11 has a through hole 111, and the battery can be inserted into the through hole 111. The clamping member 122 includes an abutment part 1221 and a connecting part 1222. The abutment part 1221 is inserted into the through hole 111. One end of the connecting part 1222 is connected to the abutment part 1221, and the other end of the connecting part 1222 is connected to the driving end of the driving member 123.

[0049] The through hole 111 in the base 11 provides a precise positioning reference for the battery, enabling the battery to fall into the predetermined position quickly and accurately when placed. Compared with placing the battery on the surface of the base 11, positioning through the through hole 111 can effectively reduce the possibility of the battery shifting in the horizontal direction, improve the positioning accuracy of the battery in the fixture, and make subsequent clamping operations more convenient.

[0050] The clamping member 122 is divided into an abutment part 1221 and a connecting part 1222 that are connected to each other. The abutment part 1221 passes through the through hole 111, which allows the abutment part 1221 to limit the battery placed in the through hole 111. At the same time, the through hole 111 also limits the maximum distance that the abutment part 1221 can move, so as to prevent the clamping member 122 from moving too far, thereby reducing the difficulty of adjusting the size.

[0051] In some alternative embodiments, the dimensions of the abutment portion 1221 in different clamping devices 12 can be set according to actual needs. Since batteries are usually cuboid in shape, the surface areas of each side of the battery are different. Therefore, the dimensions of the abutment portion 1221 can be set according to the surface area of ​​the battery to ensure that the abutment portion 1221 can press the battery well while saving the material used to manufacture the clamping member 122 and reducing costs.

[0052] In one embodiment, reference is made to Figure 1 and Figure 2 The base 11 includes a mounting plate 112 and at least two limiting plates 113. The mounting plate 112 has a through hole 111. The limiting plates 113 are inserted into the through hole 111. The abutment portion 1221 of each clamping device 12 is disposed opposite to at least one limiting plate 113. The abutment portion 1221 and the oppositely disposed limiting plate 113 are used to jointly clamp the battery carried on the base 11.

[0053] In this embodiment, the battery is fixed by the abutment portion 1221 of the clamping member 122 and the limiting plate 113 on the base 11. The through hole 111 for initial battery positioning is located on the mounting plate 112. To save material, the mounting plate 112 is typically thin. If the battery is clamped by the abutment portion 1221 engaging with the inner wall of the through hole 111, it could easily damage the battery or result in insufficient clamping. Therefore, this embodiment includes a limiting plate 113 passing through the through hole 111, thereby increasing the contact area between the base 11 and the battery, reducing the pressure on the battery during clamping, and thus reducing the probability of battery damage. It is understood that the size of the limiting plate 113 can be set according to the size of the surface of the battery in contact with the limiting plate 113; this invention does not impose any limitations on this.

[0054] In some optional embodiments, the clamping device 12 includes a first clamping device 12a, which is used to fix the battery from one side of the battery's width direction. During the movement of the connecting portion 1222 of the first clamping device 12a, the distance between the abutting portion 1221 of the first clamping device 12a and the oppositely arranged limiting plate 113 is between 25mm and 80mm. If the distance is less than 25mm, the precision requirements of the processing equipment are higher, leading to increased costs. If the distance is greater than 80mm, the length of the lead screw 121 and the size of the base 11 will increase accordingly, while the width of the battery is usually less than 80mm, which easily leads to material waste. Therefore, setting the distance between the abutting portion 1221 of the first clamping device 12a and the oppositely arranged limiting plate 113 to be between 25mm and 80mm can clamp most batteries while reducing the manufacturing cost of the battery clamp 1.

[0055] In one embodiment, reference is made to Figures 2 to 4 The clamping device 12 includes a first clamping device 12a and a second clamping device 12b. Both the first clamping device 12a and the second clamping device 12b include a lead screw 121 and a clamping member 122. The lead screw 121 is tractively connected to the clamping member 122. The rotation of the lead screw 121 can drive the clamping member 122 to move along the extension direction H1 of the lead screw, so that the clamping member 122 presses the battery supported on the base 11. The lead screw 121 in the first clamping device 12a and the lead screw 121 in the second clamping device 12b extend in different directions, so that the first clamping device 12a and the second clamping device 12b clamp different sides of the battery.

[0056] Since both the first clamping device 12a and the second clamping device 12b include a lead screw 121 and a clamping member 122, the position of the clamping member 122 in both devices can be adjusted. Therefore, in this embodiment, the two lead screws are designed with different extension directions H1, allowing the first clamping device 12a and the second clamping device 12b to clamp different sides of the battery, thus enabling adjustment for the length and width of the replaced battery. For example, if a small-sized battery is replaced with a large-sized battery, even if the length and width of the battery change, it is only necessary to adjust the first clamping device 12a and the second clamping device 12b to the appropriate position to complete the clamping of the battery. Furthermore, since both the first clamping device 12a and the second clamping device 12b use the lead screw 121 to drive the clamping member 122, the range of movement of the clamping member 122 can be set by controlling the length of the lead screw 121. This results in a simple structure, small footprint, and a large adjustment range, thus adapting to more types of batteries.

[0057] This embodiment of the utility model, by setting a first clamping device 12a and a second clamping device 12b that can clamp different sides of the battery, only requires adjusting the first clamping device 12a and the second clamping device 12b in sequence to adapt to the width and length of the replaced battery, which greatly improves the versatility of the battery clamp 1 and reduces production costs.

[0058] In one embodiment, reference is made to Figure 4 The clamping device 12 also includes a bearing 124, which is disposed on the mounting plate 112 and is rotatably connected to the end of the lead screw 121 near the clamping member 122.

[0059] The bearing 124 at the end of the lead screw 121 provides stable support for the lead screw 121, ensuring that the lead screw 121 maintains good straightness during rotation and reducing the probability of deviation or wobbling during rotation, so that the clamping member 122 can firmly hold the battery. At the same time, compared with other devices, the friction between the bearing 124 and the lead screw 121 is smaller, making the lead screw 121 rotate more easily, thereby reducing the difficulty of operation.

[0060] In one embodiment, reference is made to Figure 4 The connecting part 1222 includes a limiting groove 1222a facing the bearing 124, and at least a portion of the bearing 124 is accommodated in the limiting groove 1222a.

[0061] In this embodiment, by providing a limiting groove 1222a on the connecting part 1222, the bearing 124 can be partially accommodated within the limiting groove 1222a, thereby saving installation space for the bearing 124. Furthermore, the limiting groove 1222a ensures that the bearing 124 guides the limiting groove 1222a when the connecting part 1222 moves back and forth, reducing the probability of significant displacement of the clamping member 122.

[0062] In one embodiment, reference is made to Figure 2 and Figure 5 The bottom surface of the mounting plate 112 is provided with at least two guide rails 114, and at least a portion of each clamping device 12 is slidably connected to the base 11 via the guide rails 114.

[0063] In this embodiment, the clamping device 12 is disposed on the bottom surface of the mounting plate 112. Without affecting the normal use of the clamping device 12, the space occupied by the clamping device 12 is further reduced, making the installation of the entire battery clamp 1 more convenient. At least a portion of the clamping device 12 is slidably connected to the base 11 via the guide rail 114. For example, the clamping member 122 in the clamping device 12 can be slidably connected to the guide rail 114, which facilitates the guidance of the clamping member 122 along a straight line through the guide rail 114, reducing the probability of deviation.

[0064] In one embodiment, reference is made to Figure 4 and Figure 5 The end of the lead screw 121 furthest from the clamping member 122 is located outside the base 11 and is provided with a crank handle 1211. By providing a crank handle 1211 at the end of the lead screw 121, the user can manually rotate the lead screw 121 through the crank handle 1211, thereby controlling the clamping member 122 to clamp the battery, making operation more convenient.

[0065] In one embodiment, reference is made to Figure 1 and Figure 2 The base 11 also includes a lifting mechanism 115, which is located at the bottom of the base 11 to support the battery and adjust its position along the direction of gravity H2. Since different types of batteries have different heights, a lifting device is provided to support the battery, allowing the user to control the lifting device to adjust the battery's position along the direction of gravity H2. This ensures that the clamping device can be held in the appropriate position on the battery, making the clamping more stable and facilitating subsequent testing, assembly, or welding of the battery.

[0066] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
