In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0027] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, a modular desktop double-sided friction stir welding device includes a base 1 and a bracket 2 fixedly installed on the base 1, and a workbench 3 is arranged on the bracket 2;

[0028] It further includes a column 4 slidably installed on the base 1 and driven by a transverse movement driving member installed on the base 1. Two two-dimensional moving members are arranged on the column 4, and an upper machine head 7 and a lower machine head 8 are respectively installed on the two two-dimensional moving members, and the upper machine head 7 and the lower machine head 8 are arranged opposite to each other;

[0029] It further includes a connecting frame 10 detachably connecting the two two-dimensional moving members.

[0030] In this embodiment, according to different usage requirements, the upper welding head 7 or the lower welding head 8 can be made to perform friction welding operations. It is also possible to connect two two-dimensional moving parts through the connecting frame 10 to synchronously perform friction welding operations on the upper and lower surfaces of the workpiece by the upper welding head 7 and the lower welding head 8, which improves the welding efficiency and welding flexibility to a certain extent, enables the equipment to adapt to different welding situations, realizes the switching between single-sided welding and double-sided welding, and can flexibly adjust the welding direction and position to meet different welding requirements.

[0031] Among them, double-sided friction stir welding can effectively improve the deformation problem during the welding process by welding simultaneously from the upper and lower surfaces of the workpiece. It can act symmetrically on both sides of the weld seam, thereby reducing the asymmetric heat input and stress distribution generated during the welding process, making the weld seam more uniform and stable, and thus improving the welding quality.

[0032] At the same time, the two-dimensional moving parts are arranged to cooperate with the crosswise driving parts to drive the movement of the column 4, realizing the three-dimensional position transformation of the upper welding head 7 and the lower welding head 8, enhancing the applicable range and welding flexibility of the equipment, and enabling the welding equipment to adapt to the welding requirements of workpieces with different sizes and shapes.

[0033] In one embodiment, the crosswise driving part includes a rack plate formed on the base 1 and a gear arranged on the column 4 and meshing with the rack plate. The gear is driven to rotate by a servo motor installed on the column 4, so as to cooperate with the action of the rack plate to realize the directional movement of the column 4 on the base 1.

[0034] In another embodiment, the crosswise driving part includes a lead screw rotatably installed on the base 1 and a servo motor installed on the base 1 for driving the lead screw to rotate. A threaded sleeve is fixed on the column 4, and the threaded sleeve is in threaded connection with the lead screw. When the servo motor drives the lead screw to rotate, the column 4 is driven to move directionally on the base 1 through the action of the threaded sleeve.

[0035] In order to realize the stability of the movement of the column 4 relative to the base 1, at least two guide rails 9 are fixed on the base 1, and the guide rails 9 are in sliding fit with the second sliding grooves 402 fixed on the column 4.

[0036] Furthermore, the two-dimensional moving part includes a transverse moving part 5 and a vertical linear driver 6. The vertical linear driver 6 is connected with the transverse moving part 5.

Among them, at least one slide rail 501 is fixed on one side of the transverse moving part 5 facing the column 4, and a first sliding groove 401 in sliding fit with the slide rail 501 is arranged on the column 4.

[0037] Among them, the horizontal driving member includes a rack plate formed on the transverse moving member 5 and a gear disposed on the column 4 and meshing with the rack plate. The gear is driven to rotate by a servo motor mounted on the column 4, so as to cooperate with the action of the rack plate to realize the directional movement of the transverse moving member 5 relative to the column 4.

[0038] Further, the connecting frame 10 is detachably connected to the two transverse moving members 5. Specifically, after the connecting frame 10 is placed between the two transverse moving members 5, it can be fixed by a fixing plate and bolts. In detail, after the connecting frame 10 is placed between the two transverse moving members 5, the fixing plate is attached to one side of the transverse moving member 5 and the connecting frame 10, and then bolts are passed through the through holes on the fixing plate and fixed to the transverse moving member 5 and the connecting frame 10, so as to achieve stable installation.

[0039] When the upper machine head 7 and the lower machine head 8 perform friction welding synchronously, the upper machine head 7 and the lower machine head 8 can contact the workpiece simultaneously. A hollow groove is formed on the workbench 3, and the lower machine head 8 can pass through the hollow groove to contact the workpiece, so as to perform the welding action.
