Detailed Implementation

[0025] 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.

[0026] This utility model provides a positioning and clamping device for welding sheet metal chassis plates, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the positioning and clamping device for welding sheet metal chassis includes a welding table 1, a clamping table 2 disposed above the welding table 1, a first support frame 3 fixedly installed on the welding table 1, a movable table 10 fixedly installed on the welding table 1, and an adjustment mechanism disposed above the first support frame 3 for processing non-coplanar sheet metal.

[0027] The adjustment mechanism includes a gear ring 4 fixedly mounted on the first support frame 3, a drive gear 5 rotatably mounted on the first support frame 3, a first motor 6 fixedly mounted on the bottom of the first support frame 3, a driven gear 7 movably mounted on the top of the first support frame 3, a connecting plate 8 rotatably mounted on the driven gear 7, a connecting column 9 fixedly mounted on the connecting plate 8, a cross slide groove 11 opened on the top of the moving table 10 for the clamping table 2 to slide, and a guide groove 12 opened inside the moving table 10 for the connecting column 9 to slide.

[0028] The driving gear 5 meshes with the driven gear 7, the driven gear 7 meshes with the gear ring 4, the output end of the first motor 6 passes through the first support frame 3 and is fixedly connected to the driving gear 5, the clamping table 2 is rotatably connected to the side surface of the connecting column 9, and the moving table 10 is set above the first support frame 3.

[0029] When using the positioning and clamping device for welding sheet metal chassis plates, firstly, the welding table 1 is placed in a suitable position. Then, the position of the clamping table 2 is adjusted through the adjustment mechanism. The first motor 6 is started, and the output end of the first motor 6 drives the drive gear 5 to rotate. Since the drive gear 5 meshes with the driven gear 7, the driven gear 7 also rotates. Because the driven gear 7 meshes with the gear ring 4, the rotation of the driven gear 7 will follow the trajectory of the gear ring 4, thus realizing the circular motion of the driven gear 7. The rotation of the driven gear 7 drives the connecting plate 8 and the connecting column 9 to move synchronously. Since the clamping table 2 is rotated and connected to the connecting plate 8, the welding table 1 is placed in a suitable position. The position of the clamping table 2 is adjusted through the welding table 1. The position of the clamping table 2 is adjusted through the welding table 1. The position of the clamping table 2 is adjusted through the welding table 1. The position of the clamping table 1 ... The side surface of the connecting column 9 allows the clamping table 2 to adjust accordingly with the movement of the connecting column 9, enabling clamping of plates at different positions. Meanwhile, the guide groove 12 inside the moving table 10 provides guidance for the sliding of the connecting column 9, ensuring the stability of the clamping table 2 during adjustment. The clamping table 2 slides within the cross groove 11, allowing it to move in different directions, further improving the flexibility and accuracy of clamping. Through the design of the adjustment mechanism, this positioning clamping device can effectively clamp non-coplanar plates, greatly improving the efficiency and precision of welding processing.

[0030] Furthermore, to make the connecting plate 8 move even more smoothly, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a roller 13 is rotatably connected to the side surface of the connecting column 9, and a slide rail 14 is provided at the bottom of the moving platform 10. The side surface of the roller 13 is in contact with the inner wall of the slide rail 14.

[0031] When using the positioning and clamping device for welding sheet metal chassis plates, the rollers 13 rotate inside the slide rail 14 during the movement of the moving table 10. The configuration of the rollers 13 reduces the friction between the connecting plate 8 and the moving table 10, making the movement of the connecting plate 8 smoother and thus improving the operating efficiency of the entire device. The slide rail 14 provides a stable moving path for the rollers 13, ensuring the straightness and accuracy of the connecting plate 8 during movement. In addition, the close fit design between the rollers 13 and the slide rail 14 effectively prevents the connecting plate 8 from shaking or shifting during movement, further improving the stability and accuracy of the clamping table 2 during adjustment. This not only improves the overall performance of the positioning and clamping device but also provides more reliable technical support for the welding of chassis plates.

[0032] It should be noted that, in order to clamp plates of different thicknesses, orientations, and non-coplanar surfaces, such as... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a second support frame 15 is fixedly connected to the top of the clamping platform 2, a rotating seat 17 is rotatably connected to the top of the second support frame 15, and a second motor 16 is fixedly connected to the bottom of the second support frame 15.

[0033] The output end of the second motor 16 passes through the second support frame 15 and is fixedly connected to the bottom of the rotating seat 17. The top of the rotating seat 17 is fixedly connected to the upright plate 18.

[0034] An electric push rod 19 is fixedly connected to one side of the upright plate 18. The movable end of the electric push rod 19 passes through the upright plate 18, and a clamping plate 20 is fixedly connected to the movable end of the electric push rod 19.

[0035] When using this positioning and clamping device for welding sheet metal chassis plates, the second motor 16 drives the rotating seat 17 to rotate on the second support frame 15, thereby causing the upright plate 18 and its electric push rod 19 and clamping plate 20 to rotate together. This rotation function allows the clamping table 2 to flexibly adjust the clamping direction to adapt to the clamping requirements of plates in different directions. At the same time, the telescopic function of the electric push rod 19 allows the clamping plate 20 to move closer to or further away from the clamped plate, achieving stable clamping of plates of different thicknesses. Non-coplanar plates can also achieve the ideal clamping effect by adjusting the angle of the rotating seat 17 and the telescopic length of the electric push rod 19, ensuring the stability and accuracy of the welding process. This design greatly enhances the flexibility and practicality of the positioning and clamping device, providing a more convenient and efficient solution for the welding of sheet metal chassis plates.

[0036] 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.
