Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy vehicle body manufacturing technology, and in particular to a device for controlling welding instability and deformation of aluminum alloy thin plate components for rail vehicles. Background Technology

[0002] After the aluminum alloy sheet components of rail vehicles are welded and cooled, the weld shrinkage causes local compressive stress, making the weld area tight and the surrounding area loose. This results in misalignment and waviness in the sheet components during the welding process, which cannot meet the design appearance quality requirements.

[0003] First, when assembling aluminum alloy sheet components, they must not be tightly fitted to the tooling support. When welding sheet components, it is necessary to ensure that the sheet is rigidly fixed and that no displacement or deformation occurs. When tack-fixing sheet components, place a pressure iron on them. During the welding process of the robotic arm, the uneven temperature distribution on the cross-section causes the butt joint to open and bend in the plane. The transverse shrinkage of the welded joints causes the sheet components to move closer together, resulting in misalignment of the unwelded joints near the welded joints, making it impossible to continue welding.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a device for controlling welding instability and deformation of aluminum alloy thin plate components for rail vehicles. Utility Model Content

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] See Figures 1 to 3 As shown;

[0039] The device for controlling welding instability and deformation of aluminum alloy sheet components in rail vehicles according to this embodiment includes:

[0040] Tooling body 1;

[0041] Multiple support components 2 are installed on the main body 1 of the tooling and extend along the length of the main body 1; and

[0042] Clamping assembly 3 is used in conjunction with support assembly 2;

[0043] The aluminum alloy sheet component is placed on the tooling body 1 and supported by multiple support components 2 at the bottom of the aluminum alloy sheet component;

[0044] The clamping component 3 is pressed against the upper surface of the aluminum alloy sheet component, and the clamping component 3 and the support component 2 are arranged in a staggered manner.

[0045] Specifically, this embodiment discloses a device for controlling welding instability and deformation of aluminum alloy thin plate components for rail vehicles. It includes a tooling body 1, a support component 2, and a clamping component 3 used in conjunction with the support component 2. According to the position of the support component 2, the clamping component 3 is staggered with the support component 2 and clamps and supports the upper and lower surfaces of the aluminum alloy thin plate component respectively, thereby ensuring that there is no displacement or misalignment during welding.

[0046] Preferably, the tooling body 1 of this embodiment includes a bottom longitudinal beam 101; and a plurality of supporting crossbeams 102 disposed between the two bottom longitudinal beams 101, the plurality of supporting crossbeams 102 being spaced apart along the length direction of the bottom longitudinal beams 101;

[0047] The support beam 102 is provided with vertical plate bases 103 at intervals along its length, and vertical plates 104 are installed on the vertical plate bases 103.

[0048] The support component 2 is mounted on the tooling body 1 via the upright plate 104.

[0049] Based on the structure of the tooling body 1 described above, this embodiment further defines the structure of the support component 2 integrated on the tooling body 1, specifically: the support component 2 includes side plates 201 on both sides of the support component 2; and multiple lifting and adjusting structures disposed between the two side plates 201, the upper end of the lifting and adjusting structures supporting the crossbeam 204, the crossbeam 204 being used to fit the lower surface of the aluminum alloy sheet component and support the aluminum alloy sheet component.

[0050] In this embodiment, the lifting adjustment structure is a vertically arranged adjusting screw 202, and the upper end of the adjusting screw 202 is a support groove 203. The crossbeam 204 is placed in the support groove 203 of multiple lifting adjustment structures.

[0051] Preferably, the clamping assembly 3 in this embodiment includes a clamping block 301; and adjusting screws 202 disposed on both sides of the clamping block 301;

[0052] The lower surface of the clamping block 301 is used to clamp the upper surface of the aluminum alloy sheet.

Adjust the position of the clamping component 3 according to the position adjusted by the lifting and adjusting structure of the support component 2, so that it is staggered with the support component 2. Ensure that the support below the weld area is staggered and clamped, ensuring that there is no displacement or misalignment during welding. The lifting and adjusting structure tightly presses the crossbeam 204 against the weld overturning side to ensure no gaps and ensures that the weld is dragged and subjected to an upward force to prevent depressions on both sides of the weld during welding. Before welding, measure the flatness of the weld area at 3 meters and 1 mm. Different welding currents and voltages are used for different plate thicknesses to prevent excessive welding parameters and excessive heat input, which may lead to misalignment, waves, and breakdown.

[0055] The device of this utility model ensures that the area below the weld seam is supported and alternately pressed by the support component 2 and the pressing component 3 arranged in a staggered manner on the upper and lower surfaces of the aluminum alloy thin plate, so as to ensure that there is no displacement or misalignment during welding.
