[0038] The technical solutions of the present application will be further described below in conjunction with the drawings and through specific embodiments.

[0039] Embodiment one

[0040] The embodiment of the present application provides a battery clamping jig, which can effectively improve the clamping effect on the battery, and has good clamping effect on batteries with different outer diameters.

[0041] It needs to be explained that the battery referred to in the embodiment is a cylindrical battery. The existing battery clamp can only clamp the bottom end of the battery. In the case of a long battery, the battery may not be clamped tightly, and the battery may be inclined or shaken, which affects production.

[0042] Please refer to Figures 1 to 9 , the battery clamping fixture includes a fixed support 1 and a clamping assembly 2; the fixed support 1 serves to support other components, and the fixed support 1 includes a support ring 11 and a support bottom plate 12 arranged at intervals; as Figure 1 , the battery is inserted from the middle of the support ring 11 and finally clamped by the clamping assembly 2 to achieve fixation, as Figure 6 , the support ring 11 and the support bottom plate 12 are fixedly connected to ensure the stability of the structure.

[0043] The clamping assembly 2 includes a planetary gear train 3, a rotating ring 4, and M clamping sliders 5 slidingly installed on the support ring 11 to clamp the battery, and the M clamping sliders 5 are arranged at intervals on the rotating ring 4; in the embodiment, the side of the support ring 11 close to the support bottom plate 12 is provided with a sliding groove 1101, the clamping slider 5 is slidingly installed in the sliding groove 1101, and the extension direction of the sliding groove 1101 passes through the center line of the support ring 11.

[0044] The planetary gear train 3 includes a sun gear 31, a ring gear 32, and a plurality of planet gears 33. The sun gear 31 and the planet gears 33 are engaged, the planet gears 33 are engaged with the ring gear 32, the sun gear 31 and the planet gears 33 are rotatably installed on the support bottom plate 12, and each planet gear 33 is provided with a clamping column 301 for clamping one end of the battery, and a plurality of clamping columns 301 are arranged in a circular array around the center line of the sun gear 31; the ring gear 32 is fixedly connected with the rotating ring 4 so that the rotating ring 4 can rotate synchronously with the ring gear 32, and the rotating ring 4 is used to push the clamping slider 5 to slide towards the battery to clamp the battery. The structure of the sun gear 31, the planet gears 33 and the clamping columns 301 is shown in Figure 8 , wherein the dashed line indicates that the distance from each clamping column 301 to the center line of the sun gear 31 is equal, that is, after the battery is clamped, the center line of the battery will coincide with the center line of the sun gear 31.

[0045] Specifically, when the sun gear 31 drives a plurality of planet gears 33 to rotate synchronously in a first direction to clamp a plurality of clamping columns 301 to clamp the battery, the rotating ring 4 rotates in the opposite direction of the first direction to push the M clamping sliders 5 to clamp the battery synchronously.

[0046] Please refer to Figure 6 , Figure 7 and Figure 8 , the linkage action process of each component in the battery clamping fixture in the embodiment is as follows:

[0047] ①The sun gear 31 is driven to drive the planetary gear 33 to rotate, so that the clamping columns 301 on each planetary gear 33 move towards the battery; wherein the sun gear 31 can be driven by other various driving devices, such as motor drive, magnetic attraction drive, elastic component drive, etc.

[0048] ②During the rotation of the planetary gear 33 in the first direction, the ring gear 32 rotates in the opposite direction of the first direction, and the ring gear 32 drives the rotating ring 4 to rotate synchronously, that is, the rotating ring 4 rotating in the opposite direction of the first direction pushes the clamping slider 5 to slide towards the battery.

[0049] ③While the plurality of clamping columns 301 clamp the bottom end of the battery, the M clamping sliders 5 clamp the middle or upper outer periphery of the battery at the same time, so that the battery is clamped more stably.

[0050] The battery clamping structure in the embodiment can clamp batteries of different diameters through the plurality of clamping columns 301 and the M clamping sliders 5, and can adapt to the clamping and fixing of batteries of different diameters, and has a wider range of adaptation. It should be further pointed out that the number of clamping columns 301 is a positive integer, and is not less than three; the number of clamping sliders 5 is a positive integer, and is not less than three. In the embodiment, the number of clamping columns 301 is five, and the number of clamping sliders 5 is three.

[0051] It should be further pointed out that the support bottom plate 12 is fixedly connected with a first fixed shaft and a second fixed shaft parallel to the first fixed shaft, the sun gear 31 is rotatably installed on the first fixed shaft, and the planetary gear 33 is installed on the second fixed shaft; that is, when the sun gear 31 rotates, it will drive the planetary gear 33 to rotate around the second fixed shaft, so that the planetary gear 33 drives the ring gear 32 to rotate around the first fixed shaft.

[0052] Optionally, as shown in Figure 2 and Figure 3 , the battery clamping jig further comprises a first magnet 61 installed on the support bottom plate 12 and a second magnet 62 embedded in the sun gear 31; when the first magnet 61 adsorbs the second magnet 62, the plurality of clamping columns 301 clamp the battery.

[0053] Specifically, when the sun gear 31 rotates to a suitable position, the first magnet 61 adsorbs the second magnet 62, that is, the adsorption force of the first magnet 61 on the second magnet 62 keeps the sun gear 31 in a suitable position, so that the clamping columns 301 and the clamping sliders 5 can maintain the state of clamping the battery, avoiding the battery from shaking or tilting.

[0054] Optionally, as shown in Figure 4 and Figure 5As shown, the battery clamping jig further comprises a bearing cup 7, the fixed support 1 and the clamping assembly 2 are installed in the bearing cup 7, the bottom wall of the bearing cup 7 is provided with a through hole 71, and an adjusting ring 72 is rotatably installed in the through hole 71, and the adjusting ring 72 is fixed on the bearing cup 7 by a fastener; wherein the support bottom plate 12 is located on one side of the upper part of the bottom wall of the bearing cup 7, and the bottom wall of the bearing cup 7 bears and positions the gear ring 32, and the gear ring 32 is arranged between the bottom wall of the bearing cup 7 and the support bottom plate 12.

[0055] The sun gear 31 has a handle part 311 extending into the through hole 71, one end of the handle part 311 is provided with a first magnet 61, and the adjusting ring 72 is provided with a second magnet 62 for attracting the first magnet 61.

[0056] Specifically, the handle part 311 can be rotated in the first direction, so that each clamping column 301 is opened, and at this time the clamping slider 5 is synchronously opened to facilitate the placement of the battery; after the battery is placed into the battery clamping jig, the handle part 311 is rotated in the opposite direction of the first direction, so that the first magnet 61 approaches the second magnet 62, the first magnet 61 and the second magnet 62 are attracted to each other, so that the battery is kept in the clamped state. It should be noted that the position of the adjusting ring 72 can be adjusted, so that the second magnet 62 is in different positions, so as to adapt to clamping batteries of different diameters.

[0057] Optionally, the fixed support 1 further comprises a connecting column 13, and the rotating ring 4 is provided with a first arc-shaped through groove 401 avoiding the connecting column 13. The first arc-shaped through groove 401 can be beneficial to reduce the overall volume of the battery clamping jig.

[0058] Optionally, the support bottom plate 12 is provided with a second arc-shaped through groove 1201 avoiding the clamping column 301. Similarly, the second arc-shaped through groove 1201 can effectively reduce the overall volume of the battery clamping jig.

[0059] Optionally, the rotating ring 4 is provided with a driving groove 402, the clamping slider 5 is provided with an extension column part 501 extending towards the rotating ring 4, and the extension column part 501 extends into the driving groove 402; the driving groove 402 is an arc-shaped groove, when the rotating ring 4 rotates in the opposite direction of the first direction, the groove wall of the driving groove 402 pushes the clamping slider 5 to slide towards the battery.

[0060] Specifically, during the rotation of the rotating ring 4, the groove wall of the driving groove 402 pushes the extension column part 501, so that the clamping slider 5 slides relative to the support ring 11, so that the clamping slider 5 is close to or away from the battery. In particular, the driving groove 402 is an arc-shaped groove, so that the M clamping sliders 5 can be synchronized with the clamping columns 301 to clamp the battery. When the driving groove 402 is a straight groove, the above effect cannot be achieved. In this embodiment, the shape of the driving groove 402 is specially set based on the size parameters of the planetary gear 33 and the sun gear 31, so that the M clamping sliders 5 and the clamping columns 301 can always be synchronized to clamp the battery.

[0061] Optionally, the clamping slider 5 is provided with an elastic part at one end close to the center of the rotating ring 4. Specifically, the elastic part can play a role of elastic clamping on the one hand, avoiding clamping damage to the battery; on the other hand, the elastic part can compensate for the machining error of the planetary gear 33, the sun gear 31 and the driving groove 402, that is, when the clamping column 301 clamps the battery, the clamping slider 5 can always be in contact with the outer circumferential surface of the battery.
