[0017] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0018] like Figures 1 to 4As shown, this embodiment provides a clamp suitable for grasping the battery pack shell, including: a rotating disk 101 and a clamp bracket, a mounting substrate 201 is provided on one side of the rotating disk 101, the clamp bracket is fixedly connected to the mounting substrate 201, the clamp bracket includes a connecting beam 301 and a cross beam 302, the cross beam 302 is respectively provided with two ends of the connecting beam 301, and the two ends of the cross beam 302 are respectively provided with a clamp assembly 4. In this embodiment, the other side of the rotating disk is used to connect with an external robot arm / hand to realize automated grasping, and the clamp assembly realizes the clamping of the battery pack shell. In addition, in this embodiment, as Figure 2 As shown, the clamping jaw assembly 4 includes a cylinder mounting seat 401, which is fixedly connected to the crossbeam 302. The cylinder mounting seat 401 is provided with a cylinder 402 and a support block 403. The fixed end of the cylinder 402 is fixedly connected to the cylinder mounting seat 401, and the telescopic end of the cylinder is provided with a clamping finger 404. The clamping portion 4041 of the clamping finger 404 corresponds to the support block 403. When the robot arm drives the clamping jaw to move to the battery pack shell 5, the cylinder contracts to open the clamping finger, and the position of the clamping jaw is adjusted by the robot arm so that the edge of the battery pack shell 5 can be just placed on the support block 403. Some battery pack shells 5 have an extension portion 501 on the edge. When the extension portion 501 is aligned with the support block 403, the cylinder 402 extends at this time, so that the clamping finger just clamps the battery pack shell on the support block. After clamping, the robot arm drives the clamping jaw to move for processing.

[0019] In order to make the clamping jaw assembly more compatible with the battery pack housing, and to facilitate the arrangement of the cylinder and make the clamping fingers more compatible with the support block, in some embodiments, as Figure 4 As shown, a first platform 4011 is provided on one side of the top end of the cylinder mounting seat, and a second platform 4012 is provided on the other side. The support block is fixed on the first platform, and a through hole (not shown in the figure) is opened on the second platform. Figure 3 As shown, the cylinder sleeve is arranged in the through hole.

[0020] like Figure 2 and Figure 4 As shown, in this embodiment, the clamping jaw assembly 4 also includes a connecting rod 405, one end of the connecting rod 405 is rotatably connected to the middle of the clamping finger 404, and the other end is rotatably connected to the fixed end of the cylinder 402 or the cylinder mounting seat. In this embodiment, the other end of the connecting rod 405 is connected to the fixed end of the cylinder 402.

[0021] like Figure 4As shown, in some embodiments, the connecting beam and / or the cross beam can be set as a hollow structure, and a plurality of fixing holes 303 are set on the connecting beam and / or the cross beam. The setting of the hollow structure can effectively reduce the weight of the clamp, so that the robot arm can effectively avoid excessive load when driving the clamp; in addition, the setting of the fixing holes can realize the adjustment of the cross beam position and the position of the clamp assembly, so that the clamp in this embodiment can be suitable for the grasping of battery pack shells of different models. Specifically, as Figure 4 As shown, the connecting beam and / or the cross beam include a central tube 304 and an outer sleeve 305, the central tube 304 is sleeved in the outer sleeve 305, and the central tube 304 is fixedly connected to the inner wall of the outer sleeve 305 through reinforcing ribs 306 that are evenly distributed and scattered outward, that is, while ensuring the strength of the connecting beam and the cross beam, the weight can be effectively reduced, and the load on the robot arm can be reduced. In addition, in different embodiments of the present invention, the cross section of the connecting beam and / or the cross beam can also be a regular polygon structure, which is a regular octagon in this embodiment, so as to facilitate assembly.

[0022] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
