[0049] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0050] See also Figures 1 to 5 The utility model provides a clamping device for milling a battery busbar, including a base 1, at least one limit block 2 and a clamping assembly 3. The base 1 is formed with a supporting surface that can be raised and lowered relative to its top plane, the limit block 2 is connected to the supporting surface, and the clamping assembly 3 includes two first clamping members 31 and a second clamping member 32. The two first clamping members 31 are relatively arranged on both sides of the supporting surface and are both slidably connected to the base 1. The two first clamping members 31 can slide close to or away from the supporting surface, the second clamping member 32 is arranged relative to the limit block 2 and is slidably connected to the base 1, and the second clamping member 32 can slide close to or away from the limit block 2.

[0051] In the present device, a supporting surface is provided on the base 1, and the supporting surface can be raised and lowered relative to its top plane, and is used for placing and lifting materials. The limit block 2 is connected to the supporting surface, and two first clamping members 31 are relatively arranged on both sides of the supporting surface, and can slide towards or away from each other, and are used for clamping the materials placed on the supporting surface. The second clamping member 32 is arranged relative to the limit block 2, and can slide towards or away from the limit block 2, and is used to make the material press against the second clamping member 32 and the limit block 2, and cooperate with the two first clamping members 31 to fix the material on the supporting surface.

[0052] Compared with the prior art, two first clamping members 31 are provided on both sides of the support surface, and the two first clamping members 31 are moved closer to or farther away from each other to clamp the material, so that the material cannot slide left and right relative to the support surface. At the same time, the second clamping member 32 that can move closer to or farther away from the limit block 2 clamps the material again, so that the material cannot slide back and forth relative to the support surface. Thus, the material is clamped on the clamping surface through the cooperation of the two first clamping members 31, the limit block 2, and the second clamping member 32. The clamping force provided by the two first clamping members 31 and the second clamping member 32 can be adjusted during use, so that it can be applicable to battery cells of different lengths and widths, and the technical problem that the clamping device cannot be applicable to battery cells of different lengths and widths due to the fixed position of the clamping device cannot be applicable to battery cell specifications of different manufacturers can be solved.

[0053] Furthermore, the base 1 in the present device is a stainless steel workbench that is common and easy to purchase on the market, and is used to support the clamping device and materials. The base 1 here is a conventional setting known to those skilled in the art and will not be described in detail.

[0054] like Figures 1 to 6 As shown, the clamping device for milling the battery busbar also includes a lifting assembly 4, which includes a lifting platform 41 and a first driving member 42, a guide rail 43, two sliding blocks 44 and at least one second driving member 45, multiple support frames 46, and at least one second connecting rod 47.

[0055] Among them, a groove is opened at the top of the base 1, and the lifting platform 41 is built into the groove. The first driving member 42 has a fixed end and a movable end. The fixed end of the first driving member 42 is connected to the inner wall of the groove, and the movable end is connected to the lifting platform 41, which is used to drive the lifting platform 41 to rise and fall relative to the top plane of the base 1, and the supporting surface is connected to the lifting platform 41.

[0056] The movement of the movable end of the first driving member 42 relative to the fixed end thereof can drive the support surface, the limit block 2 and the material disposed on the lifting platform 41 to rise and fall relative to the base 1, thereby achieving the effect of lifting the material.

[0057] As an implementation method, Figures 1 to 5 As shown, the guide rail 43 is connected to the base 1, the sliding block 44 is provided with a sliding groove relative to the guide rail 43, and the two sliding blocks 44 are arranged at an interval and are both slidably connected to the guide rail 43 through the sliding groove, the first clamping member 31 is arranged in a one-to-one correspondence with the sliding block 44 and is connected to the sliding block 44, the second driving member 45 has a fixed end and an extended end, the fixed end of the second driving member 45 is hinged to one sliding block 44, and the extended end is hinged to the other sliding block 44.

[0058] The cooperation between the guide rail 43 and the sliding block 44 is used to connect and guide the two first clamping members 31 to slide toward or away from each other.

[0059] Furthermore, the sliding block 44 is slidably embedded in the guide rail 43 through the sliding groove, which will not be described in detail here.

[0060] like Figures 1 to 5 As shown, the first clamping member 31 includes a clamping rod 311 and a plurality of clamping blocks 312. The clamping rod 311 is arranged in a direction perpendicular to the guide rail 43 and is connected to the sliding block 44. The plurality of clamping blocks 312 are arranged at intervals along the length direction of the clamping rod 311, and one end of the clamping block 312 is connected to the clamping rod 311 and the other end can abut against the material.

[0061] The first clamping member 31 is composed of a clamping rod 311 and a plurality of clamping blocks 312 , which can provide a stable clamping force for the material and can be suitable for materials of different sizes.

[0062] As an implementation method, Figure 2 As shown, the first clamping member 31 further includes a plurality of cushion blocks 313 , and the cushion blocks 313 are arranged in one-to-one correspondence with the clamping blocks 312 . The cushion blocks 313 are arranged relative to the material and connected to the clamping blocks 312 .

[0063] The cushion block 313 is disposed between the clamping block 312 and the material to reduce excessive clamping force of the clamping block 312 on the material.

[0064] like Figures 1 to 5 As shown, the second clamping member 32 includes a pushing block 321 and a third driving member 322. The pushing block is arranged relative to the limit block 2. The third driving member 322 has a fixed end and an extended end. The fixed end of the third driving member 322 is connected to the base 1, and the extended end is connected to the pushing block 321, which is used to drive the pushing block 321 to slide close to or away from the limit block 2.

[0065] The third driving member 322 drives the material pushing block 321 to slide relative to the limiting block 2 , and the material between the two is locked.

[0066] As an implementation method, Figure 3 As shown, the second clamping member 32 also includes at least one guide cylinder 323 and at least one guide rod 324. The guide cylinder 323 is arranged along the telescopic direction of the extended end of the third driving member 322 and is connected to the fixed end of the third driving member 322. The guide rod 324 is arranged one-to-one with the guide cylinder 323, and one end of the guide rod 324 is connected to the pushing block 321, and the other end is connected to the guide cylinder 323 slidably inserted.

[0067] The cooperation between the guide rod 324 and the guide cylinder 323 plays a role in connecting and guiding the sliding of the pusher block 321 .

[0068] As an implementation method, Figure 4 As shown, a plurality of support frames 46 are spaced apart from each other, and the support frames 46 include two first connecting rods 461 and a support block 462. The two first connecting rods 461 are parallel to each other and spaced apart, and are both connected to the lifting platform 41. The support block 462 is connected to the two first connecting rods 461 and is disposed at one end of the first connecting rod 461 away from the lifting platform 41. The top plane of the support block 462 forms a support surface.

[0069] The plurality of support blocks 462 are connected to the lifting platform 41 via a plurality of first connecting rods 461 for supporting and connecting purposes.

[0070] Furthermore, the multiple support blocks 462 are spaced apart from each other, which not only can be used for materials of different lengths, but also reduces the weight of the support blocks 462, and is beneficial to the discharge of iron chips and cutting fluid generated during the milling process, etc., which will not be elaborated here.

[0071] Specifically, in the device, the plurality of support blocks 462 are divided into two groups, and the two groups of support blocks 462 are arranged at intervals on the lifting platform 41 to provide a stable supporting force.

[0072] As another implementation method, Figures 4 to 6 As shown, the second connecting rod 47 and the first connecting rod 461 are parallel to each other and spaced apart, and are connected to the lifting platform 41. The limit block 2 is connected to the end of the second connecting rod 47 away from the lifting platform 41, and the bottom plane of the limit block 2 is higher than the plane where the support surface is located.

[0073] The second connecting rod 47 supports the connection between the limiting block 2 and the lifting platform 41 .

[0074] As a preferred implementation, the limiting block 2 is elastic.

[0075] The elastic limit block 2 can reduce the damage to the material caused by excessive clamping force, etc., which will not be elaborated here.

[0076] Furthermore, the device also includes a PLC control component, which is electrically connected to the first drive member 42, the second drive member 45 and the third drive member 322, and is used to control the strokes of the first drive member 42, the second drive member 45 and the third drive member 322 respectively, so as to be suitable for materials of different sizes or brands. The first drive member 42, the second drive member 45 and the third drive member 322 are all common and easy-to-purchase linear drive members on the market, such as cylinders, push rod motors or hydraulic cylinders, etc., which will not be elaborated here.

[0077] According to the specific working process of the utility model, a supporting surface is provided on the base 1, and the supporting surface can be raised and lowered relative to its top plane, so as to place and lift materials; a limiting block 2 is connected to the supporting surface; two first clamping members 31 are relatively arranged on both sides of the supporting surface, and can slide towards or away from each other, so as to clamp the materials placed on the supporting surface; a second clamping member 32 is arranged relative to the limiting block 2, and can slide towards or away from the limiting block 2, so as to make the materials press against the second clamping member 32 and the limiting block 2, and cooperate with the two first clamping members 31 to fix the materials on the supporting surface. Compared with the prior art, two first clamping members 31 are provided on both sides of the support surface, and the two first clamping members 31 are moved closer to or farther away from each other, so that the material cannot slide left and right relative to the support surface. At the same time, the second clamping member 32, which can move closer to or farther away from the limit block 2, is used to clamp the material again, so that the material cannot slide back and forth relative to the support surface. Thus, the material is clamped on the clamping surface through the cooperation of the two first clamping members 31, the limit block 2, and the second clamping member 32. The clamping force provided by the two first clamping members 31 and the second clamping member 32 can be adjusted during use, so that it can be suitable for battery cells of different lengths and widths.

[0078] When in use, the user first places the material on multiple support blocks 462, then starts the first driving member 42, so that the lifting platform 41 drives the support blocks 462 and the material to be lifted to a specified height, and then starts the second driving member 45. The extended end of the second driving member 45 is shortened relative to the fixed end, and drives the relative clamping block 312 and the cushion block 313 to slide close to the material and clamp the material. Finally, the third driving member 322 is started. Under the drive of the third driving member 322, the pushing block 321 abuts against the material, and pushes the material to abut against the limit block 2, thereby clamping the material and completing the subsequent milling process.

[0079] The device, through the above structure, can solve the technical problem that the clamping device cannot be applied to battery cells of different lengths and widths due to the fixed position of the clamping device, thereby causing the clamping device to be unable to be applied to battery cell specifications of different manufacturers.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
