Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal welding, and particularly relates to a positioning fixture used for sheet metal welding. Background Art

[0002] Welding damaged sheet metal parts is one of the common methods of repairing sheet metal parts. Welding is performed at the damaged or cracked parts of sheet metal parts to connect and repair the damaged areas and restore their structural strength and integrity. However, in the current process of sheet metal positioning welding, it is not convenient to flip and adjust the sheet metal parts, which will bring some disadvantages and difficulties.

[0003] Limited flexibility in welding position: The inability to flip and adjust sheet metal parts means that welding positions are restricted. Sometimes, a specific weld needs to be welded at a different angle or direction, but the ideal welding position cannot be adjusted because the sheet metal cannot be flipped. This can lead to limitations in the welding process and fail to meet specific design and process requirements.

[0004] Increased complexity of operation and processing: The inability to flip sheet metal requires additional processes and equipment to adapt to the requirements of the welding position. This may require the design and adjustment of complex positioning devices, fixtures, and operating steps. Increased complexity of operation and processing reduces production efficiency and worker efficiency.

[0005] In summary, the inability to flip sheet metal parts to adjust the welding position in the prior art will bring a series of disadvantages, including the limitation of welding position, the difficulty in processing complex geometric shapes, the increase of operation complexity and processing complexity, and the increase of manual adjustment and correction workload. Therefore, in order to overcome these disadvantages, it is necessary to develop and adopt new innovative technologies and equipment to improve the flexibility and accuracy of sheet metal welding.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a positioning fixture for sheet metal welding, comprising: a welding table 100, a base 200 and a vertical plate 300, the vertical plate 300 is installed on the left side above the welding table 100, and a positioning plate 500 is arranged above the right side of the vertical plate 300;

[0025] A flip motor 400 is installed on the upper left side of the vertical plate 300, a positioning clamp 160 is respectively provided on the upper and lower inner sides of the positioning plate 500, a positioning pole 600 is respectively installed in the middle of the upper and lower parts of the positioning plate 500, and a straight line slide 700 is provided in the middle of the upper part of the welding table 100;

[0026] A driving motor 120 is installed in the middle of the right side of the welding table 100, a central rotating rod 130 is arranged in the middle of the inside of the welding table 100, a transverse cylinder 140 is installed on the right side of the central rotating rod 130, a connecting slider 150 is installed above the transverse cylinder 140, a movable base plate 800 is arranged in the middle of the right side of the upper surface of the welding table 100, a height adjustment rod 900 is installed above the movable base plate 800, a height adjustment support plate 110 is arranged above the height adjustment rod 900, an inner screw groove is arranged on the inner wall of the transverse cylinder 140, a thread is arranged on the outer wall of the central rotating rod 130, and the central rotating rod 130 is rotatably connected with the transverse cylinder 140 through threads.

[0027] A base 200 is installed below the welding platform 100 , and a non-slip bottom pad 170 is glued to the lower surface of the base 200 . The material of the non-slip bottom pad 170 is a wear-resistant rubber.

[0028] The front ends of the two positioning poles 600 are respectively connected to the back sides of the two positioning clamps 160, and the flip motor 400 is connected to the middle of the left side of the positioning plate 500 through the transmission shaft. Before the sheet metal is welded, the left end of the sheet metal is extended between the two positioning clamps 160, and then the two positioning poles 600 are started to drive the two positioning clamps 160 to move inward, thereby clamping the left end of the sheet metal to fix it.

[0029] The driving motor 120 is connected to the left end of the center rotating rod 130 through the transmission shaft. A bearing is installed in the middle of the left side of the welding table 100. The left end of the center rotating rod 130 is connected to the inner side of the bearing. The driving motor 120 is started to reverse. The driving motor 120 can drive the center rotating rod 130 to rotate through the transmission shaft. While the center rotating rod 130 rotates, it can drive the transverse cylinder 140 to move to the left. The transverse cylinder 140 drives the connecting slider 150 to slide in the linear slide groove 700. At the same time, the connecting slider 150 drives the height adjustment rod 900 to move to the left through the moving base plate 800. At the same time, the height adjustment support plate 110 can move to the left.

[0030] The driving motor 120 and the flipping motor 400 are both servo motors, and the height-adjusting rod 900 and the positioning rod 600 are both electric push rods. When the height-adjusting support plate 110 moves to below the supporting position at the right end of the sheet metal part, the height-adjusting rod 900 drives the height-adjusting support plate 110 to rise and contact the lower right end of the sheet metal part, thereby supporting the sheet metal part.

[0031] The front surface of the positioning plate 500 is a concave structure tilted 90 degrees to the right, and the front surfaces of the height-adjusting support plate 110 and the two positioning plates 500 are respectively coated with a rubber anti-skid layer.

[0032] The upper end of the connecting slider 150 passes through the linear slide groove 700 and is connected to the lower side of the movable bottom plate 800. The central rotating rod 130 and the transverse moving cylinder 140 are both made of stainless steel.

[0033] As an embodiment of the present invention: Figure 1 , Figure 2 as well as Figure 3 As the first embodiment of the utility model: before welding the sheet metal, the left end of the sheet metal is inserted between the two positioning clamps 160, and then the two positioning poles 600 are started to drive the two positioning clamps 160 to move inward, thereby clamping the left end of the sheet metal to fix it;

[0034] Then, the driving motor 120 is started to reverse, and the driving motor 120 can drive the central rotating rod 130 to rotate through the transmission shaft. While the central rotating rod 130 rotates, it can drive the traverse cylinder 140 to move to the left. The traverse cylinder 140 drives the connecting slide block 150 to slide in the linear slide groove 700. At the same time, the connecting slide block 150 drives the height adjustment rod 900 to move to the left through the moving bottom plate 800. At the same time, the height adjustment support plate 110 can move to the left. When the height adjustment support plate 110 moves to below the supporting position at the right end of the sheet metal part, the height adjustment rod 900 drives the height adjustment support plate 110 to rise and contact with the lower right end of the sheet metal part, so that the sheet metal part can be supported. When the driving motor 120 reverses, the height adjustment support plate 110 can move to the right.

[0035] Through the above steps, the final effect is that the sheet metal parts can be clamped to fix their positions, and the right ends of sheet metal parts of different lengths can be supported when the sheet metal parts are welded. Supporting the right end of the sheet metal part can ensure its stable positioning at the welding position, which helps to reduce welding errors and improve the accuracy and consistency of welding.

[0036] See also Figure 1 and Figure 4, as the second embodiment of the utility model: combined with the further elaboration of the first embodiment, when it is necessary to flip and adjust the welding position of the sheet metal, the height-adjusting support plate 110 is moved to the right away from the sheet metal, and then the flip motor 400 is started. The flip motor 400 can drive the positioning plate 500 to rotate through the transmission shaft, thereby driving the clamped and fixed sheet metal to flip and adjust the welding position;

[0037] Since the anti-skid bottom pad 170 is glued to the lower surface of the base 200, the anti-skid bottom pad 170 has good friction, which can prevent the welding platform 100 from sliding during welding.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
