[0022] The utility model relates to a cylindrical battery rolling groove auxiliary positioning device, which involves a cylindrical battery 1, including a base 2 with a through hole, a sleeve 3 arranged on the base 2 and two positioning mechanisms 4 arranged on the base 2. The cylindrical battery 1 can pass through the sleeve 3 and the through hole, and the sleeve 3 and the through hole do not affect the rotation of the cylindrical battery 1. The two positioning mechanisms 4 can clamp the corresponding rolling groove ends of the cylindrical battery 1 and can rotate with the cylindrical battery 1.

[0023] The cylindrical battery groove rolling auxiliary positioning device of the utility model respectively positions the cylindrical battery 1 from two parts through the sleeve 3 and the two positioning mechanisms 4, and effectively prevents the cylindrical battery 1 from shifting during the groove rolling without hindering the rotation of the cylindrical battery 1. The device has a simple structure and low manufacturing cost.

[0024] In one embodiment, see Figure 1 The two positioning mechanisms 4 each include a clamping block 401 with a concave shape on the clamping side and at least two rollers 402 rotatably arranged on both sides of the clamping side of the clamping block 401. This design can ensure that the roller 402 rotates together with the cylindrical battery 1 without hindering the rotation of the cylindrical battery 1, and in this embodiment, the roller 402 rotates concentrically with the cylindrical battery 1, and the roller 402 is made of steel.

[0025] In one embodiment, participating Figure 1 , Teflon tape is attached to the surface of the roller 402. This design can prevent the roller 402 from being worn.

[0026] In one embodiment, see Figure 1 , one of the positioning mechanisms 4 further includes a support plate 403 for supporting the clamping block 401, and the other positioning mechanism 4 further includes a cylinder 404 for pushing the clamping block 401 to move and a manual valve 405 for controlling the extension and contraction of the cylinder 404, and the support plate 403 and the manual valve 405 are both arranged on the base 2. With this design, semi-automatic control can be achieved through the manual valve 405 and the cylinder 404, and the installation of the cylindrical battery 1 is convenient, and in this embodiment, the support plate 403 and the clamping block 401 are connected by bolts.

[0027] In one embodiment, see Figure 1 , the support plate 403 is also provided with reinforcing ribs 406. Such a design increases the stability of the support plate 403.

[0028] In one embodiment, see Figure 2, the sleeve 3 is detachably arranged on the base 2. With this design, the sleeve 3 can be detachably replaced, which is convenient for replacement when damaged, and the positioning requirements of cylindrical batteries 1 with different diameters can be met by replacing the sleeve 3 with different diameters. In order to meet the positioning requirements of cylindrical batteries 1 with different diameters, a clamping block 401 with a corresponding length needs to be installed on the support plate 403.

[0029] In one embodiment, see Figure 2 and Figure 3 The base 2 is provided with a fixing block 5, and the fixing block 5 is provided with a first slide groove 501 in the vertical direction, and a plug 6 is elastically penetrated in the horizontal direction, and the plug 6 can pass through the first slide groove 501;

[0030] The sleeve 3 is provided with a limit rod 7, and the limit rod 7 is provided with a slot 701, and the limit rod 7 can be slidably matched with the first slide groove 501, and the plug 6 can be plugged and matched with the slot 701. With this design, when installing the sleeve 3, the plug 6 is first withdrawn from the first slide groove 501, and then the limit rod 7 is inserted into the first slide groove 501, and then the plug 6 is inserted into the slot 701. In this embodiment, the elastic penetration of the plug 6 is realized by a spring, and when the plug 6 is inserted into the slot 701, the spring is in a non-stretched and non-compressed state.

[0031] In one embodiment, see Figure 2 and Figure 3 The sleeve 3 is provided with a second slide groove 301, the limiting rod 7 is arranged in the second slide groove 301, and the fixing block 5 is slidably matched with the second slide groove 301. With this design, the pre-positioning can be achieved through the sliding match between the second slide groove 301 and the fixing block 5, so that the limiting rod 7 can be inserted into the first slide groove 501 conveniently.

[0032] In one embodiment, see Figure 2 and Figure 3 The ends of the limit rod 7 and the plug 6 that are close to each other are both wedge-shaped, and the wedge-shaped surfaces of the limit rod 7 and the plug 6 can fit each other. With this design, when the limit rod 7 is inserted into the first slide groove 501, the plug 6 can be automatically withdrawn from the first slide groove 501 by the downward movement of the limit rod 7, and then the plug 6 can be inserted into the slot 701 by itself due to the elasticity of the plug 6, so that only the sleeve 3 needs to be disassembled to manually operate the plug 6, and in this embodiment, the edges of the limit rod 7 and the wedge-shaped surfaces of the plug 6 are rounded.
