[0002] Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added. It is one of the light metal materials. In addition to the general properties of aluminum, aluminum alloy also has some specific properties of the alloy due to the different types and amounts of alloying elements added. The density of aluminum alloy is 2.63 - 2.85 g / cm, with relatively high strength (σb is 110 - 650 MPa). Its specific strength is close to that of high alloy steel, and its specific stiffness exceeds that of steel. It has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as a structural material, with wide applications in aerospace, aviation, transportation, construction, mechanical and electrical, light chemical industry and daily necessities.

During the fixing process, due to manual operation, the aluminum alloy may be fixed unstably, resulting in too large welding gaps. Moreover, the existing fixing method cannot be adjusted according to the size, which urgently needs to be improved. Therefore, the utility model proposes a welding equipment applied to an aluminum alloy frame body to solve the above problems. Summary of the Utility Model

Detailed Embodiment

[0017] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0018] According to Figure 1 、 2 、as shown in Figure 3, this embodiment proposes a welding device applied to an aluminum alloy frame body, including a bottom plate 1, a material bearing table 2, and a support frame 3. A material bearing table 2 is fixedly connected to the top of the bottom plate 1, and support frames 3 are symmetrically and fixedly connected to both sides of the bottom plate 1. A fixing mechanism is provided at the top of the support frame 3. A fixing frame 4 is provided on the back side of the bottom plate 1. A welding mechanism is provided at the top of the fixing frame 4. A limiting mechanism is also provided on the fixing frame 4. After drilling the aluminum alloy main pipe, it is placed on the material bearing table 2, and the position of the aluminum alloy main pipe is locked by the fixing mechanism. The aluminum alloy branch pipe to be welded is placed into the drilled hole, and the position of the aluminum alloy branch pipe is limited by the limiting mechanism to avoid unstable fixation and the problem of too large welding gaps. Then, the aluminum alloy branch pipe and the aluminum alloy main pipe are welded together by the welding mechanism.

[0019] The limiting mechanism includes a first hydraulic cylinder 5, a fixing rod 6, a second hydraulic cylinder 11, and a limiting plate 12. A first hydraulic cylinder 5 is fixedly installed at the top of the fixing frame 4. The output end of the first hydraulic cylinder 5 is fixedly connected to a fixing rod 6. A second hydraulic cylinder 11 is fixedly installed on the outside of the fixing frame 4. The output end of the second hydraulic cylinder 11 is fixedly connected to a limiting plate 12.

[0020] The position of the limiting plate 12 is perpendicular to that of the fixing rod 6. A V-shaped groove is provided inside the limiting plate 12. The shape of the fixing rod 6 is a conical structure.

[0021] After the aluminum alloy branch pipe is inserted into the aluminum alloy main pipe, the output end of the second hydraulic cylinder 11 drives the limiting plate 12 to move towards the aluminum alloy branch pipe, and the outside of the aluminum alloy branch pipe is limited by the V-shaped groove. Then, the output end of the first hydraulic cylinder 5 drives the fixing rod 6 to move downward, and the top of the aluminum alloy branch pipe is limited by the conical structure at the bottom of the fixing rod 6 to ensure the accurate docking position of the aluminum alloy branch pipe and the aluminum alloy main pipe. Then, the output end of the second hydraulic cylinder 11 drives the limiting plate 12 to reset to avoid affecting the electric welding gun 8.

[0022] The welding mechanism includes a first gear 7, an electric welding gun 8, and a connecting arm 15. A first gear 7 is rotatably connected to the outside of the fixing rod 6. The bottom of the first gear 7 is fixedly connected to a connecting arm 15. An electric welding gun 8 is fixedly installed at the bottom end of the connecting arm 15.

[0023] The top end of the fixed rod 6 is fixedly connected with an assembly plate 16. One side of the assembly plate 16 is fixedly connected with a motor 9. The output end of the motor 9 is fixedly connected with a second gear 10. The outer wall of the second gear 10 meshes with the outer wall of the first gear 7.

[0024] The output end of the motor 9 drives the second gear 10 to rotate on one side of the assembly plate 16. The second gear 10 meshes with the outer wall of the first gear 7 to drive the first gear 7 to rotate outside the fixed rod 6. The electric welding gun 8 is connected to the first gear 7 through a connecting arm 15, driving the electric welding gun 8 to make a circular motion around the aluminum alloy branch pipe, and the aluminum alloy branch pipe can be welded to the aluminum alloy main pipe.

[0025] The fixing mechanism includes a threaded rod 13 and a clamping block 14. The top of the support frame 3 is threadedly connected with the threaded rod 13. The bottom end of the threaded rod 13 is rotatably connected with the clamping block 14. The clamping block 14 is parallel to the loading platform 2 in the vertical direction.

[0026] The bottom of the clamping block 14 is provided with an arc-shaped groove. The shape of the loading platform 2 is an X-shaped structure. The top end of the threaded rod 13 is fixedly connected with a handle.

[0027] After placing the aluminum alloy main pipe on the loading platform 2, turn the threaded rod 13 clockwise by turning the handle. The threaded rod 13 is in threaded cooperation with the top of the support frame 3, which can drive the clamping block 14 to move downward. The clamping block 14 and the loading platform 2 cooperate to clamp the top and bottom of the aluminum alloy main pipe, so as to fix the aluminum alloy main pipe on the loading platform 2. After welding is completed, turn the threaded rod 13 counterclockwise by turning the handle, which can drive the clamping block 14 to move upward, so that the clamping block 14 is separated from the aluminum alloy main pipe, and the aluminum alloy frame can be taken out from the loading platform 2.

[0028] For the welding equipment of the aluminum alloy frame, after the aluminum alloy branch pipe is inserted into the aluminum alloy main pipe, the output end of the second hydraulic cylinder 11 drives the limiting plate 12 to move towards the aluminum alloy branch pipe, and the outer side of the aluminum alloy branch pipe is limited by the V-shaped groove. Then the output end of the first hydraulic cylinder 5 drives the fixed rod 6 to move downward, and the top end of the aluminum alloy branch pipe is limited by the conical structure at the bottom end of the fixed rod 6 to ensure the accurate docking position of the aluminum alloy branch pipe and the aluminum alloy main pipe. After that, the output end of the second hydraulic cylinder 11 drives the limiting plate 12 to reset to avoid affecting the electric welding gun 8.
