As a result, sheet metal parts are easily skewed and offset during the welding process, resulting in defects such as unevenness, bending and distortion on the surface of the welded parts.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, the utility model provides a CNC welding machine for repairing automobile sheet metal parts, comprising a welding table 1, two moving components 2 are symmetrically installed on the top of the welding table 1, a control component 3 is installed on the top of the two moving components 2, a welder 4 is installed on the bottom of the control component 3, a storage plate 5 is installed in the center of the top of the welding table 1, and positioning mechanisms 6 are installed on both sides of the storage plate 5;

[0026] The positioning mechanism 6 includes a fixed frame 61, and sliding rods 62 are fixedly connected to the top of both sides of the fixed frame 61, and a movable plate 65 is installed on the inner side of the fixed frame 61, and driving rods 651 are fixedly connected to both sides of the bottom of the movable plate 65, and a moving block 66 is arranged under the movable plate 65, and a driving groove 662 is opened on the surface of the moving block 66, and the driving rod 651 is slidably connected to the driving groove 662, and an extrusion block 663 is fixedly connected to one side of the bottom end of the moving block 66, and sliding blocks 661 are fixedly connected to both sides of the moving block 66, and a slide rail 67 is slidably connected to one side of the slide rail 661, and one end of the slide rail 67 is fixedly connected to the inner wall of the fixed frame 61.

[0027] The specific settings and functions of this embodiment are described in detail below. Under the control of the control component 3, the push rod 42 of the welder 4 drives the movable plate 65 to move downward to weld the sheet metal. During this process, the movable plate 65 applies a force to the extrusion block 663 to squeeze the top of the sheet metal. At the same time, the driving rod 651 of the movable plate 65 slides inside the driving groove 662 and drives the two moving blocks 66 to move toward each other. In this way, the positioning blocks 652 of the two moving blocks 66 can position the sheet metal to prevent it from being displaced during the processing, thereby effectively avoiding the situation where the welding of the sheet metal is skewed and offset.

[0028] Embodiment 2

[0029] like Figure 3 and Figure 4 As shown, both sides of the movable plate 65 are fixedly connected with the lifting plate 63, and the lifting plate 63 is slidably connected with the slide bar 62. The surface of the slide bar 62 is sleeved with a spring 64, and the spring 64 is located between the lifting plate 63 and the fixed frame 61. Both sides of the fixed frame 61 are provided with guide holes 612, and the lifting plate 63 is slidably connected with the guide holes 612. The bottom of the movable plate 65 is fixedly connected with a positioning block 652, and the top of the fixed frame 61 is provided with a moving hole 611. Both sides of the welder 4 are fixedly connected with the connecting plate 41, and the bottom of the connecting plate 41 is fixedly connected with a push rod 42. The push rod 42 is slidably connected with the moving hole 611, and the push rod 42 abuts against the top of the movable plate 65.

[0030] The effect achieved by the whole embodiment is that when the movable plate 65 moves downward, it drives the lifting plate 63 to move together. When the lifting plate 63 slides inside the guide hole 612, it also slides on the surface of the slide bar 62, thereby exerting pressure on the spring 64 on the surface of the slide bar 62. This causes the spring 64 to begin to compress. When the welder 4 completes welding and moves upward, the push rod 42 no longer exerts pressure on the movable plate 65. At this time, the spring 64 begins to reset and drives the lifting plate 63 and the movable plate 65 to reset together.

[0031] In addition, when the push rod 42 moves following the welder 4 , it can slide inside the moving hole 611 , ensuring that it can continuously apply pressure to the movable plate 65 .

[0032] The method of use and working principle of the device: Under the control of the control component 3, the welder 4 moves downward to weld the sheet metal. During this process, the push rod 42 applies a force to the movable plate 65, causing it to squeeze the top of the sheet metal when it moves downward. This squeezing effect helps to ensure the quality of welding and keep the sheet metal stable. At the same time, the driving rod 651 of the movable plate 65 slides inside the driving groove 662, thereby driving the two moving blocks 66 to move toward each other. This design enables the two moving blocks 66 to more accurately control the position of the sheet metal and ensure its stability during the welding process.

[0033] In addition, when the movable plate 65 moves downward, it drives the lifting plate 63 to move. When the lifting plate 63 slides inside the guide hole 612, it also slides on the surface of the slide bar 62, exerting pressure on the spring 64 on the surface of the slide bar 62. This design utilizes the elasticity of the spring so that the lifting plate 63 and the movable plate 65 can quickly return to their original positions when subjected to external forces, thereby ensuring the continuity and stability of the welding process.

[0034] The positioning block 652 at the bottom is used to position the sheet metal part, which can prevent it from being displaced during the processing, thereby avoiding the situation where the sheet metal part is skewed or offset during welding. The design of the positioning block 652 takes into account the different sizes and shapes of the sheet metal parts, so that it can adapt to various welding requirements. When the welding is completed, the push rod 42 no longer applies pressure to the movable plate 65, and the spring 64 begins to reset, so that the lifting plate 63 drives the movable plate 65 to reset together. This reset mechanism ensures that the welding equipment can quickly return to the initial state and prepare for the next welding.

[0035] In addition, the push rod 42 can slide inside the moving hole 611 when following the movement of the welder 4, thereby ensuring that the movable plate 65 can still perform the extrusion operation. This design enables the push rod 42 to adjust its position accordingly as the welder 4 moves, ensuring effective control and positioning of the sheet metal during the entire welding process.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
