[0043] According to the utility model, a stirring welding tool is provided, which comprises a processing platform 10, a clamping device and a side pressure device.

[0044] Hereinafter, the specific structures of the above-mentioned components of the stirring welding tool according to the present embodiment will be described.

[0045] In this embodiment, if Figures 1 to 3 As shown, the processing platform 10 is horizontally arranged. The processing platform 10 preferably adopts a welding structure in which a square steel frame is arranged at the bottom of a steel plate, so as to ensure the reliable strength of the processing platform 10 and avoid deformation of the stirring welding tooling.

[0046] Furthermore, the processing platform 10 has a plurality of processing stations arranged at intervals along the first direction D1; the workpiece is fixed on the processing station and can perform front and back side welding operations. For example, after completing front side welding at one processing station, the workpiece can be quickly moved to the next processing station for back side welding operations.

[0047] In this embodiment, if Figures 1 to 3 As shown, the clamping device is arranged on the processing platform 10, and the clamping device includes a translation assembly and a pressing member 20 connected to the translation assembly. The pressing member 20 can be formed into a flat plate structure driven by a cylinder, an oil cylinder or a motor to reciprocate in the vertical direction to press the workpiece toward the processing platform 10. The translation assembly can reciprocate along the first direction D1 to drive the pressing member 20 to move to different processing stations, thereby realizing the free switching of the pressing member 20 between different processing stations.

[0048] Specifically, in this embodiment, Figures 1 to 3 As shown, the translation assembly includes a driving assembly and a sliding member 43, the driving assembly is formed with a driving end 411 that reciprocates along the first direction D1; the sliding member 43 is fixedly connected to the driving end 411, so that the driving assembly drives the sliding member 43 to reciprocate along the first direction D1; the sliding member 43 is formed into a frame structure and is arranged above the processing platform 10, and the lower pressing member 20 is detachably connected to the sliding member 43, thereby realizing that the driving assembly can drive the lower pressing member 20 to reciprocate along the first direction D1. In this embodiment, the driving assembly can be a device such as a telescopic cylinder or a motor screw, as long as it has a driving end 411 that can reciprocate along the first direction D1.

[0049] In a preferred embodiment, Figures 1 to 3 As shown, two drive assemblies are provided, and the two drive assemblies are respectively provided at the two sides of the processing station in the second direction D2, the second direction D2 is perpendicular to the first direction D1, and the plane formed by the first direction D1 and the second direction D2 is parallel to the processing platform 10. The sliding member 43 is formed into an inverted U-shaped structure, and the pressing member 20 is installed and fixed at the bottom of the U-shaped structure. The inverted U-shaped structure allows the pressing member 20 to be arranged in the groove formed by the U-shaped structure. The driving ends 411 of the two drive assemblies are respectively connected to the two side walls of the sliding member 43, so that the two drive assemblies can synchronously drive the sliding member 43 to reciprocate along the first direction D1, thereby ensuring that the sliding member 43 is evenly stressed and moves smoothly.

[0050] Specifically, in this embodiment, Figures 1 to 3As shown, the driving assembly includes a first driving member 41 and a second driving member 42. The first driving member 41 and the second driving member 42 can both be formed as a telescopic cylinder or a motor screw structure. The driving end 411 is located on the first driving member 41, and the driving end 411 can drive the sliding member 43 to reciprocate between different processing stations; the second driving member 42 is connected to the first driving member 41, so that the second driving member 42 can drive the first driving member 41 and the sliding member 43 to move synchronously, thereby increasing the reciprocating motion stroke of the driving assembly, so that the sliding member 43 moves to leave the processing platform 10, thereby facilitating the installation and disassembly of the workpiece and the cleaning of the processing platform 10.

[0051] Furthermore, in this embodiment, if Figures 1 to 3 As shown, the translation assembly also includes a slide rail 44 extending along the first direction D1, and the slide rail 44 is installed on the processing platform 10; a recessed slide groove is formed at the bottom of the sliding member 43, and the slide groove is slidably connected to the slide rail 44, so that the slide rail 44 can guide the reciprocating movement of the sliding member 43, thereby reducing the load on the driving end 411, thereby extending the service life of the clamping device.

[0052] In a preferred embodiment, Figures 1 to 3 As shown, a plurality of pressing members 20 are provided, and the plurality of pressing members 20 are arranged in an array, so as to improve the reliability of the pressing members 20 in fixing the workpiece. The plurality of pressing members 20 can be arranged in a rectangular array.

[0053] In this embodiment, if Figures 1 to 3 As shown, the side pressure device is arranged on the processing platform 10, and the side pressure device includes a limit member 31 and a side push member 32. The limit member 31 and the side push member 32 are respectively located at the two ends of the processing station in the first direction D1, so that the side push member 32 and the limit member 31 are respectively located on the two sides of the workpiece opposite to each other. The side push member 32 can be a telescopic device such as an oil cylinder or an air cylinder. The side push member 32 pushes one side of the workpiece so that the other side of the workpiece abuts against the limit member 31. In this way, the outward tension generated during the welding process can be effectively controlled to avoid deformation of the workpiece, thereby ensuring the welding quality.

[0054] In a preferred embodiment, Figures 1 to 3 As shown, the side pressure device is arranged one by one with the processing platform 10. In each side pressure device, the limiter 31 is formed into a strip structure extending along the second direction D2; a plurality of side pushers 32 are arranged, and the plurality of side pushers 32 are arranged at intervals along the length direction of the limiter 31, so that the plurality of side pushers 32 jointly push the workpiece until the workpiece abuts against the limiter 31, thereby preventing the workpiece from being skewed. The limiter 31 is preferably made of a strip of solid steel plate to ensure the support strength of the side of the workpiece and ensure the welding quality.

[0055] In this embodiment, if Figures 1 to 3As shown, the stirring welding tool also includes a support member 50, which is arranged at the processing station. The support member 50 is formed into a plate-like structure extending in the horizontal direction to support the workpiece. The top of the support member 50 is arranged horizontally to ensure the stability of the welding quality of the workpiece.

[0056] Welding can easily cause the ends of the workpiece to warp, and the flatness of the workpiece cannot be guaranteed. Figures 1 to 3 As shown, the stirring welding tool also includes an anti-deformation member 60, which is formed into a strip structure and is arranged in the middle position of the support member 50 in the first direction D1, and supports the middle part of the workpiece, thereby offsetting the deformation of the two ends of the workpiece after welding, so that the workpiece remains horizontal after welding. The size of the anti-deformation member 60 in the height direction is adjustable, and the flatness of different workpieces after welding is ensured by adjusting the size of the anti-deformation member 60 in the height direction.

[0057] It should be noted that the anti-deformation part 60 can be adjusted in the height direction by replacing the anti-deformation part 60 with a different thickness or by providing a bolt at the bottom of the anti-deformation part 60, which is connected to the support part 50. By adjusting the length of the bolt extending out of the anti-deformation part 60, the distance between the anti-deformation part 60 and the support part 50 can be adjusted, thereby adjusting the size of the anti-deformation part in the height direction.

[0058] In addition, in this embodiment, Figure 1 As shown, the stirring welding tool also includes an error-proofing part 70, which is arranged on the side of the processing station, and a groove is arranged on the side of the workpiece. The error-proofing part 70 is formed with an error-proofing pin 71 that can extend into the groove. The error-proofing part 70 is arranged on one side of the processing station in the second direction D2, and the error-proofing pin 71 can slide along the second direction D2. Before welding, it is determined that the error-proofing pin 71 can extend into the groove on the side of the workpiece, indicating that the surface to be processed of the workpiece is correct, to prevent wrong material processing.

[0059] The stirring welding tooling of the utility model has a compact structure and a small size, and has a plurality of processing stations on the processing platform, so that rapid switching between front and back side welding can be achieved on the same tooling, thereby improving processing efficiency and reducing processing costs; the clamping device can be freely switched between different processing stations to achieve effective fixation of the workpiece, thereby improving welding quality; the side pressure device can clamp the two ends of the workpiece, thereby effectively controlling the outward tension during the welding process and further improving welding quality; in addition, the various devices in the stirring welding tooling move in a coordinated manner and can be applied to workpieces of different specifications and sizes, meeting the stir friction welding requirements of aluminum alloy battery boxes.

[0060] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
