The welding component is connected to the worktable and is used for welding thin plates and profiles.

[0004] The transverse and longitudinal moving parts of the above-mentioned device are linear motion parts, which are inconvenient for handling curved thin plates, such as the chamfer of components.

[0005] Therefore, it is necessary to provide an aluminum alloy sheet welding device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides an aluminum alloy thin plate welding device that can assist workers in welding curved aluminum alloy thin plates.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Aluminum alloy welding is widely used in production. For example, in the manufacturing process of aluminum alloy doors and windows, aluminum alloy sheets and tubes are processed according to the designed patterns. Curved lines are often used at the corners of aluminum alloy doors and windows. Workers usually cut the aluminum alloy sheets into the corresponding sizes and shapes first, and then weld the cut curved parts into a whole. This process is done manually by workers based on their experience. During welding, there are problems such as the inaccuracy of the perpendicularity between the two aluminum alloy sheets.

[0027] First embodiment:

[0028] like Figure 1-6As shown, the aluminum alloy thin plate welding device provided by this utility model includes: a base plate 104, which is a welding platform on which a welding part 201 cut to a certain specification and shape is placed. The welding part 201 shown in the figure includes two parts, namely a vertical arc plate and a horizontal arc plate, which need to be welded and fixed together perpendicular to each other and in corresponding positions. The base plate 104 is provided with a first sliding groove 101 and a second sliding groove 102, which are located on the same straight line. The base plate 104 is also provided with a third sliding groove 103, which is perpendicular to the first sliding groove 101 and the second sliding groove 102. The first sliding groove 101, the second sliding groove 102 and the third sliding groove 103 are perpendicular to each other. The side wall is provided with a slide rail 112, which is a groove perpendicular to the cross section of the bottom plate 104. Fixing components 105 are slidably installed in the first slide groove 101, the second slide groove 102, and the third slide groove 103, respectively. Each fixing component 105 includes a sliding plate 106, which is installed in the slide rail 112. Therefore, the sliding plate 106 can slide within the slide rail 112. A rotating shaft 107 is rotatably installed at the upper end of the sliding plate 106. A fitting column 108 is provided on the rotating shaft 107, and a slot is provided on the fitting column 108. The two ends of the vertical arc plate of the welded part 201 are engaged in the slots of the fitting column 108 located in the first slide groove 101 and the second slide groove 102. A bolt 110 is provided at the lower end of the sliding plate 106. The shape and position of the bolt 110 are as follows... Figure 5 As shown, the upper half of the bolt 110 is threadedly connected to the slide plate 106, and the lower half is a bolt cap. The bolt cap is wider than the first slide groove 101, the second slide groove 102, and the third slide groove 103 and is located at their lower ends. In use, firstly, the horizontal arc plate of the welded part 201 is placed on the base plate 104, and then the two ends of the vertical arc plate are locked into the slots of the fitting column 108 located in the first slide groove 101 and the second slide groove 102. The fixing components 105 in the first slide groove 101 and the second slide groove 102 are pushed. As the two fixing components 105 approach each other, they squeeze the vertical arc plate of the welded part 201, causing the vertical arc plate to bend. During this process, the fitting column 108 is pushed by the vertical arc plate of the welded part 201 and rotates. When the vertical arc plate... When the curvature of the plate is consistent with the curvature of the transverse arc plate, the bolt 110 at the lower end of the base plate 104 is rotated. The bolt 110 increases the friction between the slide plate 106 and the slide rail 112, thereby fixing the slide plate 106 in the slide rail 112. The fitting column 108 of the fixing component 105 in the third slide groove 103 is used differently from the fitting column 108 of the fixing component 105 in the first slide groove 101 and the second slide groove 102. The fitting column 108 of the fixing component 105 in the third slide groove 103 is used to slightly squeeze and temporarily fix the top of the vertical arc plate of the welded part 201 after bending, to prevent the vertical arc plate of the welded part 201 from being displaced by the welding gun during welding. Finally, the upper and lower parts of the corresponding welded parts 201 are welded together as a whole.

[0029] By setting the fitting column 108, the aluminum alloy plate can be bent and fixed, which helps the staff to position the aluminum alloy sheet to be welded, thereby improving the welding accuracy of the curved aluminum alloy plate.

[0030] Second embodiment:

[0031] like Figure 6 As shown, the rotating shaft 107 is threadedly connected to the fitting column 108. The rotating shaft 107 is a threaded rod with a certain length. The fitting column 108 can stay at different positions on the rotating shaft 107, thereby adjusting the overall height of the rotating shaft 107 and the fitting column 108.

[0032] The threaded connection between the rotating shaft 107 and the fitting column 108 facilitates the adaptation of welded parts 201 longitudinal plates of different heights. For longitudinal plates with greater height, the position of the fitting column 108 on the rotating shaft 107 can be raised, thereby clamping the fitting column 108 at the upper end of the longitudinal plate to obtain a more stable clamping effect.

[0033] Third embodiment:

[0034] like Figure 2 As shown, the fitting column 108 of the fixing component 105 located in the third groove 103 is provided with a tip 111 on one side. The tip 111 is a pointed cone structure protruding from the surface of the fitting column 108. Its surface has a small contact area with the welding part 201, thereby providing the operator with a larger welding operation space.

[0035] Fourth embodiment:

[0036] like Figure 6 As shown, the fitting column 108 has a clamping plate 109 on its side wall. The space between the two clamping plates 109 is the placement position for the end part of the welding part 201. Unlike the fitting column 108 with a slot, the end of the welding part 201 is located outside the fitting column 108, which facilitates the welding of the vertical arc plate and the horizontal arc plate of the welding part 201 located in the clamping plate 109.

[0037] Fifth embodiment:

[0038] like Figure 6 As shown, the clamping plate 109 is arc-shaped, and the arc-shaped clamping plate 109 fits more closely with the outer wall of the arc-shaped aluminum alloy welded part 201, thereby improving the stability of clamping.

[0039] Working principle: First, the horizontal arc plate of the welding component 201 is placed on the base plate 104. Then, the two ends of the vertical arc plate are engaged in the grooves of the fitting column 108 located in the first slide groove 101 and the second slide groove 102. The fixing components 105 in the first slide groove 101 and the second slide groove 102 are pushed. As the two fixing components 105 approach each other, they compress the vertical arc plate of the welding component 201, causing the vertical arc plate to bend. Finally, the upper and lower parts of the corresponding welding component 201 are welded together as a whole. The above embodiment is only one of the preferred embodiments of this utility model and should not be used to limit the protection scope of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not substantial in nature, but solve the same technical problem as this utility model, should be included within the protection scope of this utility model.
