Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an auxiliary rotating mechanism for sheet metal welding processing. Background Technology

[0002] Sheet metal welding is a process that uses heating, high temperature or high pressure to melt or plastically deform the joints of metal sheets, thereby achieving a firm connection between the metal sheets. Welding uses a heat source (such as electric arc, laser, resistance heat, etc.) to locally heat the metal sheets to be welded to a molten state. Then, during the cooling process, the molten metal atoms rearrange and combine together to form a weld, thus achieving the connection between the metal sheets.

[0003] Chinese Patent Publication No. CN220388450U discloses a sheet metal welding device, including a worktable. A welding machine is mounted on the top of the worktable, an adjustment mechanism is provided on the worktable, and rotating mechanisms are located at the bottom and top of the worktable. Clamping mechanisms are provided on both the adjustment and rotating mechanisms, and a protractor is mounted on the top of the worktable. This invention uses two sets of clamping mechanisms to clamp and fix two sets of sheet metal sheets. The extension end of a first electric push rod causes the sheet metal sheet on the surface of an inclined plate to flip, thereby adjusting the angle of the sheet metal sheet. Rotation of the horizontal axis causes an indicator rod to rotate. Because the indicator rod is parallel to the inclined plate, the angles of the indicator rod and the inclined plate are equal, and the inclined plate and the indicator rod flip simultaneously. The angle of the inclined plate is determined by the scale corresponding to the surface of the protractor when the indicator rod flips, thereby increasing the accuracy of sheet metal welding.

[0004] In the aforementioned prior art, two sheet metal parts to be welded can be placed on a rotating plate and an inclined plate respectively, so that their welding points are close together for welding. However, in order to improve the welding stability of the sheet metal parts, it is usually necessary to weld on both sides of the welding point. This device is not convenient for flipping and adjusting the orientation of the sheet metal parts. After welding one side, it is necessary to take the sheet metal parts that have been initially welded and manually flip and adjust them for welding, which is quite cumbersome. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an auxiliary rotating mechanism for sheet metal welding, thereby solving the problem that the sheet metal welding device in the background art is inconvenient to rotate and adjust the orientation of the sheet metal parts, requiring manual rotation and adjustment of the welding parts for welding, which is quite cumbersome.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] Example 1:

[0052] like Figures 1 to 6 As shown, this utility model provides an auxiliary rotating mechanism for sheet metal welding processing, including: a movable frame 1 and a support frame 101 rotatably mounted on the movable frame 1 for supporting the movable frame 1, a clamping structure arranged inside the movable frame 1 for clamping and fixing the sheet metal part, and a displacement structure arranged on the clamping structure for adjusting the horizontal position of the clamping structure.

[0053] The clamping structure is arranged in two sets. Each set of clamping structures includes a support plate 2 movably installed inside the movable frame 1 for placing sheet metal parts, a U-shaped frame 201 arranged on one side of the support plate 2, a threaded sleeve 202 arranged on the U-shaped frame 201, an adjusting screw 203 threaded inside the threaded sleeve 202, and a pressure plate 204 arranged at one end of the adjusting screw 203 for pressing the sheet metal parts. The two sheet metal parts to be welded are placed between the support plate 2 and the pressure plate 204 respectively. Then, the adjusting screw 203 is rotated to move the pressure plate 204 and press the sheet metal parts onto the support plate 2, thereby fixing the position of the sheet metal parts.

[0054] The displacement structure includes two threaded sliders 3 slidably installed inside the movable frame 1, a fixed shaft 301 arranged between the two threaded sliders 3 and rotatably installed inside the support plate 2 as the fulcrum of the support plate 2, and an adjustment component arranged on the threaded sliders 3 for adjusting the position of the threaded sliders 3. When the threaded sliders 3 move, they can drive the fixed shaft 301 to move, so that the fixed shaft 301 drives the support plate 2 to move, thereby adjusting the distance between the sheet metal parts on both sides.

[0055] Specifically, the adjustment component includes a limiting screw 302 rotatably installed inside the movable frame 1, the limiting screw 302 being threaded inside the threaded slider 3, and a knob 303 arranged at one end of the limiting screw 302. Rotating the knob 303 drives the limiting screw 302 to rotate, and the rotating limiting screw 302 drives the threaded slider 3 to slide through the threaded engagement with the threaded slider 3.

[0056] The displacement structure also includes a guide hole 304 inside the movable frame 1 for limiting the movement direction of the threaded slider 3. The threaded slider 3 is slidably installed inside the guide hole 304. When the threaded slider 3 moves, it slides inside the guide hole 304, thereby limiting the movement direction of the threaded slider 3.

[0057] Example 2:

[0058] Based on Embodiment 1, in order to facilitate the adjustment of the angle of the two side support plates 2, a limiting structure for limiting or adjusting the angle of the clamping structure is arranged on the clamping structure.

[0059] The limiting structure includes a compression screw 4 threaded inside the support plate 2, and a rubber block 401 arranged at one end of the compression screw 4 and in contact with the outer surface of the fixed shaft 301 for compressing the fixed shaft 301. Rotating the compression screw 4 can cause it to move the rubber block 401 through the threaded engagement with the support plate 2, so that the rubber block 401 is released from the compression of the fixed shaft 301. Then the support plate 2 can be flipped to adjust the angle of the sheet metal part.

[0060] The limiting structure also includes several protrusions 402 arranged on the surface of the fixed shaft 301 to increase friction. The roughness of the surface of the fixed shaft 301 can be increased by setting the protrusions 402, so that the rubber abutment 401 can press more tightly on the protrusions 402.

[0061] Example 3:

[0062] Based on Example 1, after welding one side of the sheet metal part, in order to facilitate flipping the sheet metal part to weld the other side, a flipping structure for flipping and adjusting the orientation of the clamping structure is arranged on the movable frame 1 and the clamping structure.

[0063] The flipping structure includes a connecting shaft 5 rotatably installed inside the support frame 101 and arranged on one side of the movable frame 1 as the rotation fulcrum of the movable frame 1; a worm gear 501 fixedly sleeved on the connecting shaft 5; a bearing seat 502 arranged on one side of the support frame 101; a worm 503 rotatably installed inside the bearing seat 502 and meshing with the worm gear 501; and a handle 504 arranged at one end of the worm 503. Rotating the handle 504 drives the worm 503 to rotate. The rotating worm 503 can drive the connecting shaft 5 to rotate through meshing with the worm gear 501, so that the connecting shaft 5 drives the movable frame 1 to rotate, thereby flipping the sheet metal part to adjust its orientation.

[0064] Working principle: During use, place the two sheet metal parts to be welded on the two support plates 2 respectively, positioning them between the support plates 2 and the pressure plate 204. Then, rotate the adjusting screw 203. The adjusting screw 203 moves through its threaded engagement with the threaded sleeve 202, causing the pressure plate 204 to move and press the sheet metal parts onto the support plates 2, thus fixing their position. After fixing the sheet metal parts on both sides, rotate the corresponding pressing screw 4. The rotating pressing screw 4, through its threaded engagement with the support plates 2, moves the rubber abutment 401, causing it to disengage from the pressure on the protrusion 402 on the fixed shaft 301, thereby... Release the angle restriction on support plate 2, then flip support plate 2 to adjust the angle of sheet metal parts. After completion, reverse the rotation of extrusion screw 4, causing extrusion screw 4 to drive rubber block 401 to press back onto protrusion 402, thereby re-fixing the angle of support plate 2. Then, rotate the corresponding knob 303 to drive limit screw 302 to rotate. The rotating limit screw 302, through its threaded engagement with threaded slider 3, drives threaded slider 3 to slide within guide hole 304. The moving threaded slider 3 drives fixed shaft 301 to move, causing fixed shaft 301 to drive support plate 2 to move, thereby adjusting the distance between the sheet metal parts on both sides and making the sheet metal parts on both sides contact. (See reference...) Figure 1 The state is set up for welding operations. After welding on one side is completed, the handle 504 can be rotated to drive the worm 503 to rotate inside the bearing 502. The rotating worm 503 can drive the connecting shaft 5 to rotate through meshing with the worm wheel 501. This causes the connecting shaft 5 to drive the movable frame 1 to rotate, thereby flipping the sheet metal part to adjust its orientation, so as to weld and reinforce the flipped side of the sheet metal part.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
