[0002] In fields such as machinery manufacturing and construction engineering, large-size sheet metal parts are widely used due to their advantages such as high structural strength and convenient assembly. Their welding quality directly affects the stability of the overall equipment or structure.

[0003] The existing application publication number CN221791568U discloses a sheet metal welding anti-deformation device, including a platform, with support legs fixedly installed at the four corners of the bottom of the platform, and a mounting hole with an open front side on the top of the platform. A bearing seat is fixedly installed on the left inner wall of the mounting hole, and a rotating shaft is rotatably installed on the right side of the bearing seat. A first electric telescopic rod is fixedly installed on the right outer wall of the platform, and a horizontal hole is opened on the right inner wall of the mounting hole.

[0004] However, this solution has many drawbacks: the support points are mostly concentrated at the edge of the workpiece, and there is a lack of targeted support in the middle, which makes the workpiece prone to warping, bending and other deformations under the action of concentrated thermal stress, making it difficult to meet the requirements of high-precision welding; in addition, the device is not convenient for adjusting the position when loading materials, which seriously affects the efficiency of welding operations.

[0005] Therefore, those skilled in the art urgently need to develop a welding deformation-resistant support structure for large-size sheet metal parts. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding deformation-resistant support structure for large-size sheet metal parts.

The bottom support plate is symmetrically provided with side support plates on its front and rear sides. Multiple second pulleys are rotatably mounted on the adjacent sides of the two side support plates. A bracket is provided at the bottom of each side support plate. The bracket is connected to the adjacent side support plate by a first electric telescopic rod. The bottom support plate is symmetrically provided with clamping boxes on both the front and rear sides. The cross-section of the two clamping boxes is C-shaped and the openings are arranged opposite each other. The bottom of each clamping box is connected to the base through a support leg. The two clamping boxes are arranged on the same plane as the two side support plates.

[0008] Preferably, a second electric telescopic rod is fixedly mounted on the top of each clamping box, and a clamping plate is correspondingly provided inside each clamping box. The output end of the second electric telescopic rod extends vertically downward into the clamping box and is connected to the clamping plate.

[0009] Preferably, each first pulley is detachably and fixedly connected to the bottom support plate via a first pulley bracket, and each second pulley is detachably and fixedly connected to the adjacent side support plate via a second pulley bracket.

[0010] Preferably, the number of lifting cylinders is two, and the two lifting cylinders are synchronously driven cylinders.

[0011] Preferably, there are two first electric telescopic rods on each side, and the four first electric telescopic rods are synchronous electric telescopic rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are: It achieves multi-directional balanced support, reduces welding deformation of large sheet metal parts, and ensures the forming accuracy of the workpiece; the rolling support structure reduces the frictional resistance between the workpiece and the support surface, and the adjustable support components simplify the clamping and positioning process, improving the convenience of loading and operation efficiency.

[0018] Please see Figures 1-3 This utility model provides an embodiment: a large-size sheet metal welding anti-deformation support structure, including a base 1, a horizontally placed bottom support plate 2 above the base 1, a plurality of first pulleys 3 rotatably mounted on the upper surface of the bottom support plate 2, each first pulley 3 being detachably and fixedly connected to the bottom support plate 2 through a first pulley bracket; the top surfaces of all the first pulleys 3 are coplanar and horizontal, and a lifting cylinder 9 is provided between the base 1 and the bottom support plate 2; the cylinder body of the lifting cylinder 9 is detachably and fixedly connected to the base 1, and the top of the piston rod is welded and fixedly fixed to the lower surface of the bottom support plate 2 at the center position.

[0019] The base 1 is provided with guide sleeves on both sides corresponding to the lifting cylinder 9 (not shown in the figure), and the bottom support plate 2 is provided with guide columns that slide with the guide sleeves to achieve smooth guidance during the lifting process.

[0020] Side support plates 6 are symmetrically arranged on the front and rear sides of the bottom support plate 2. Multiple second pulleys 4 are rotatably mounted on the adjacent sides of the two side support plates 6. Each second pulley 4 is detachably and fixedly connected to the adjacent side support plate 6 through a second pulley bracket. The outer end faces of the second pulleys 4 are coplanar and perpendicular to the top face of the first pulley 3. A bracket 5 is correspondingly arranged at the bottom of each side support plate 6. The bracket 5 is connected to the adjacent side support plate 6 through a first electric telescopic rod 7. The cylinder of the first electric telescopic rod 7 is bolted to the bracket 5, and the end of the telescopic rod is welded and fixed to the outer wall of the side support plate 6.

[0021] The bottom support plate 2 is symmetrically provided with clamping boxes 8 on both the front and rear sides. The cross-section of the two clamping boxes 8 is C-shaped and the openings are arranged opposite each other. The bottom of each clamping box 8 is connected to the base 1 through the support leg 12. The two clamping boxes 8 are coplanar with the two side support plates 6. The top of each clamping box 8 is fixedly equipped with a second electric telescopic rod 11. The inside of each clamping box 8 is correspondingly provided with a clamping plate 10. The output end of the second electric telescopic rod 11 extends vertically downward into the clamping box 8 and is connected to the clamping plate 10.

[0022] The lower surface of the clamping plate 10 is bonded with an anti-slip rubber pad, and the two side walls of the clamping plate 10 slide against the inner side wall of the clamping box 8 to ensure vertical guidance during the pressing process.

[0023] Both the first pulley 3 and the second pulley 4 are made of polyurethane and have anti-slip textures on the surface to prevent scratches on the sheet metal surface. The side of the second pulley 4 is a U-shaped structure with a groove in the middle. Both the first pulley bracket and the second pulley bracket are made of L-shaped steel plate structure and can be detachably connected to the corresponding support plate by bolts, which facilitates the replacement and maintenance of the pulleys.

[0024] Furthermore, there are two lifting cylinders 9, which are synchronously driven; there are two first electric telescopic rods 7 on each side, and the four first electric telescopic rods 7 are synchronously driven. All electric telescopic rods and lifting cylinders are equipped with stroke limiters to prevent excessive extension and retraction from causing structural damage.

[0025] Working principle of this utility model: 1. Place the sheet metal to be welded flat on the first pulley 3. Start the lifting cylinder 9 through the PLC controller to drive the bottom support plate 2 to rise to a certain height. At the same time, start the first electric telescopic rod 7 to drive the side support plates 6 on both sides to slide along the base 1. Adjust the distance between the second pulleys 4 on both sides to match the width of the sheet metal and limit its movement.

[0026] 2. Utilizing the rolling characteristics of the first pulley 3, the sheet metal part can be easily pushed to adjust its front and rear position, allowing it to slide easily into the clamping box 8. The second pulleys 4 on both sides fit against the front and rear side walls of the sheet metal part, forming a lateral limit to prevent the sheet metal part from shifting laterally.

[0027] 3. Start the second electric telescopic rod 11 at the top of the clamping box 8 to drive the clamping plate 10 to move vertically downward until the anti-slip rubber pad on the lower surface of the clamping plate 10 is tightly attached to the upper surface of the sheet metal part, so as to achieve top pressing and fixing. At this time, the sheet metal part is supported at the bottom, limited on both sides, and pressed at the top, so that it cannot produce warping, side bending or other deformations, which facilitates subsequent welding.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
