Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding, and in particular to a sheet metal welding positioning and clamping structure. Background Art

[0002] When the existing sheet metal welding positioning clamping structure is in use, personnel realize the operation of motor one by controlling the switch group. When the motor one is running, the output shaft of motor one rotates to drive the rotating column to rotate. The rotation of the rotating column drives the driving gear to rotate. The driving gear rotates to make the front and rear rack plates move toward each other, thereby making the longitudinally adjacent sliding rods move toward each other. The movement of the sliding rod drives the transversely adjacent connecting plates to move toward each other, thereby making the transverse splints move toward each other inside the transverse slide groove, thereby realizing the transverse clamping and positioning of the sheet metal. After the positioning and clamping are stable, personnel turn off the motor and realize the operation of motor two by controlling the switch group. When the motor two is running, the output shaft of motor two rotates to drive the bidirectional screw to rotate. The rotation of the bidirectional screw makes the sliding seat inside the longitudinal slide groove and moves toward each other under the guiding action of the guide column. The sliding seat moves toward each other, driving the vertically adjacent longitudinal splints to move toward each other, thereby realizing the longitudinal positioning and clamping of the sheet metal.

[0003] The above-mentioned sheet metal welding positioning clamping structure can apply force evenly and stably fix rectangular sheet metal parts with regular shapes. However, for sheet metal parts with irregular shapes, the standard clamping structure cannot evenly apply sufficient clamping force to these sheet metal parts. The main reason is that some areas are not suitable for contact due to the clamp design or structural shape, resulting in uneven force distribution, which makes the sheet metal parts prone to displacement during the welding process. Therefore, a sheet metal welding positioning clamping structure is needed. Utility Model Content

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The existing sheet metal welding positioning clamping structure can evenly apply force and stably fix regular rectangular sheet metal parts. However, for irregularly shaped sheet metal parts, the standard clamping structure cannot evenly apply sufficient clamping force to these sheet metal parts. The main reason is that some areas are not suitable for contact due to the clamp design or structural shape, resulting in uneven force distribution, which makes the sheet metal parts easily move during the welding process. Figure 1-Figure 4 This embodiment provides a sheet metal welding positioning clamping structure, including a base plate 1 and a welding platform 2 fixed on the top of the base plate 1.

[0022] refer to Figure 2-Figure 4As shown, for sheet metal parts with irregular shapes, the standard clamping structure cannot evenly apply sufficient clamping force to these shaped sheet metal parts. The main reason is that some areas are not suitable for contact due to the fixture design or structural shape, resulting in uneven force distribution, which makes the sheet metal parts easy to displace during the welding process. In order to effectively improve the positioning and clamping effect of irregular shaped sheet metal parts and ensure the welding quality, the following settings are specially made: a locking assembly 3 is provided on the top of the welding table 2, and the locking assembly 3 includes a slide plate 32 arranged on the top of the base plate 1, and a leveling rod 312 is fixed to the top of the welding table 2. The outer wall of the leveling rod 312 is in contact with one side of the slide plate 32 to restore the reset slide plate 32 to its original state. An adjustment plate 31 is also hinged on one side of the skateboard 32, and two mounting plates 33 are symmetrically fixed on the other side of the skateboard 32. Positioning balls 34 are fixed on the end faces of the two mounting plates 33. A power assembly is provided on the top of the base plate 1, and the power assembly includes a motor 35 fixed on the top of the base plate 1. A bidirectional threaded screw 36 is fixed to the output end of the motor 35. The outer wall of the bidirectional threaded screw 36 is threadedly connected to two push plates 37. A limit assembly is provided on the top of the base plate 1 to limit the moving range of the two push plates 37. The limit assembly includes a limit slider fixed to the bottom of the push plate 37. A limit slot is provided on the top of the base plate 1. The limit slider slides left and right along the length direction of the limit slot. The positioning ball 34 is moved by the power assembly to achieve positioning and clamping of regular or irregular shaped sheet metal parts. The sheet metal to be welded is placed on the top of the welding table 2. The motor 35 drives the bidirectional threaded screw 36 to achieve precise movement of the push plate 37, thereby accurately controlling the relative position of the adjustment plate 31 and the slide 32. This allows the clamp to be adaptively adjusted according to the actual shape of the sheet metal. Using the four positioning balls 34 as positioning points can effectively solve the positioning problem of different edges of the sheet metal. The positioning balls 34 can adaptively adjust the edges of irregularly shaped sheet metal parts through the movement of the adjustment plate 31 and the slide 32 to ensure that each edge is clamped, thereby avoiding displacement during the welding process. At the same time, through the relative movement of the adjustment plate 31 and the slide 32, the positioning balls 34 can distribute the clamping force according to the edge contour of the sheet metal part, which helps to improve the stability of the clamping and avoid deformation or movement of irregular sheet metal parts due to uneven clamping. Through effective positioning and clamping, this design can prevent displacement of sheet metal parts during welding and ensure the accuracy and consistency of welding.

[0023] refer to Figure 3As shown, a protective sleeve is fixed to the outer wall of the positioning ball 34, and the material of the protective sleeve includes but is not limited to rubber material. The rubber protective sleeve can enhance the friction between the positioning ball 34 and the contact surface of the sheet metal, and prevent the positioning ball 34 from slipping due to the smooth or hard surface of the sheet metal, thereby improving the stability of the clamping and reducing the displacement of the sheet metal during the welding process. At the same time, the rubber material has good cushioning and flexibility properties, which can effectively reduce the direct contact between the positioning ball 34 and the sheet metal, and avoid scratches or damage to the sheet metal by the hard metal surface. Especially when the surface of the sheet metal is relatively delicate or the coating is thin, the protective effect is particularly important. At the same time, the rubber material has strong adaptability and can provide better clamping force and protection on different sheet metal surfaces (such as smooth, irregular or coated surfaces), avoiding uneven clamping or damage due to surface differences.

[0024] refer to Figure 2-Figure 3 As shown, a rectangular frame plate 38 is fixed to the side of the pushing plate 37, and an adjustment component connected to the adjustment plate 31 is provided inside the rectangular frame plate 38. The adjustment component includes a slide rod 39 fixed to the inner wall of the rectangular frame plate 38, and the outer wall of the slide rod 39 is provided with a spring 310 and an adjustment block 311. The two ends of the spring 310 are respectively fixed to the adjustment block 311 and the rectangular frame plate 38, and the adjustment block 311 is fixed to the adjustment plate 31. If the two sides of the edge of the irregularly shaped sheet metal are not symmetrical, the adjustment block 311 slides outside the slide rod 39 to squeeze the spring 310 to adjust the position of the positioning ball 34. The coverage of the clamping area can be flexibly adjusted according to the different sizes and shapes of the sheet metal. This allows for wider application to sheet metal parts of various shapes and sizes, regardless of whether the edges are symmetrical or regular. Through the combination of the adjustment block 311 and the spring 310, more precise adjustment control can be achieved, so that the positioning point of each positioning ball 34 can be fine-tuned according to actual needs to ensure stable clamping of the sheet metal part and avoid positioning errors or uneven clamping forces caused by asymmetry or complex shapes. In this process, the spring 310 can not only provide the necessary pressure to ensure that the positioning ball 34 remains in the set position, but also maintain good adaptability and elastic adjustment when the shape of the sheet metal part changes slightly, thereby avoiding inaccurate positioning due to external forces or operational errors.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
