Description

Technical Field

[0001] This utility model relates to the field of automotive welding, specifically a welding frame for automotive welding production. Background Technology

[0002] Welding is a technique that joins metals together by heating them at high temperatures. It is commonly used in automobile manufacturing. During the welding process, parts are often connected to form an integral structure to ensure the strength of the structure. Some items need to be welded on both sides, so manual flipping is often required during the welding process.

[0003] According to publicly available patent CN218396772U, a welding frame for automotive welding production includes a main body, a tilting mechanism, and a fixing mechanism. The tilting mechanism is located at the upper end of the main body, and the fixing mechanism is located above the main body and inside the tilting mechanism. The main body includes a base plate, a support column, an anti-slip pad, an electric push rod, and a pushing rod. The support column is fixedly installed at the lower end of the base plate, the anti-slip pad is fixedly installed at the lower end of the support column, and the electric push rod is fixedly installed at the left and right ends of the upper end of the base plate. In the process of realizing this utility model, the inventors discovered that at least the following problems in the prior art remain unsolved. The solution involves installing a flipping mechanism to facilitate the flipping of welded items. The flipping is simple and quick, saving workers from manual flipping steps, reducing labor intensity, improving work efficiency, and enhancing safety during the flipping process, thus protecting workers' lives. However, in traditional welding, components are placed inside the welding frame, making it inconvenient for workers to weld the sides of the components. Furthermore, the sliding connection of the limiting block within the limiting groove causes the fixing rod to move during welding, making it easy for two welded components to separate, thus affecting the quality of the weld. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a welding frame for automobile welding production. This solves the technical problems of the current welding process, where welding parts are placed inside the welding frame, which makes it inconvenient for personnel to weld the sides of the parts. Furthermore, the limiting block slides in the limiting groove, causing the fixing rod to move during the welding of the parts, which makes it easy for the two parts to separate and thus affects the quality of the welding.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A welding frame for automotive welding production is designed, including a U-shaped frame. Connecting shafts are rotatably connected to both sides of the inner cavity of the U-shaped frame, and both connecting shafts pass through and are placed on the outer side of the U-shaped frame. Connecting plates are installed at opposite ends of the two connecting shafts, and connecting seats are installed on both sides of opposite ends of the two connecting plates. Support rods are rotatably connected to the inner sides of the four connecting seats via rotating shafts. Cylinders are installed in the middle of opposite ends of the two connecting plates. Baffles are provided at the driving ends of the two cylinders. Rectangular grooves are opened at the ends of the two baffles near the cylinders. Sliding grooves are opened at the upper and lower ends of the inner cavities of the two rectangular grooves. Two sliders are slidably connected in each of the four sliding grooves. Pins are fixedly connected between the upper and lower sliders in the rectangular grooves on the same side, and one end of the support rod is rotatably connected to the outside of the pins. Clamping mechanisms are provided at opposite ends of the two baffles, and driving mechanisms are provided at the outer ends of the two connecting shafts.

[0006] Preferably, the drive mechanism includes a driven gear mounted on one end of two connecting shafts and a dual-axis motor mounted on the bottom of the U-shaped frame. Both drive ends of the dual-axis motor are equipped with driving gears, and the two driving gears mesh with the two driven gears respectively.

[0007] Preferably, the clamping mechanism includes a base plate installed at one end of two baffles. Adjustment grooves are provided on both sides of the two baffles at their opposite ends. Adjustment blocks are slidably connected in the two adjustment grooves on the same side. A clamping plate is connected between the two adjustment blocks on the same side. A screw rod passes through the clamping plate and the base plate on the same side. Nuts are threaded onto the outer sides of the screw rod above the clamping plate and the screw rod below the base plate.

[0008] Preferably, a light-shielding plate is provided on the top of the U-shaped frame, and the light-shielding plate is hinged to the U-shaped frame via a hinge.

[0009] Preferably, protective covers are provided on both sides of the U-shaped frame, and the protective covers are transparent.

[0010] Preferably, both the upper and lower ends of the screw are fixedly connected to a limiting plate, and the size of the limiting plate is larger than the size of the screw.

[0011] Preferably, rubber pads are installed at opposite ends of the clamping plate and the base plate, and the rubber pads are elastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a U-shaped frame, connecting shaft, cylinder, baffle, rectangular groove, sliding groove, slider, support rod, connecting seat, and clamping mechanism to install the automotive parts to be welded on the clamping mechanisms on both sides. Then, the cylinder is activated to work with the support rod to push the two clamped parts closer to each other and into contact. This ensures that the welding position of the clamped automotive parts is unobstructed, making it easier for personnel to weld the sides of the automotive parts. Furthermore, the two automotive parts are pressed and contacted each other during welding, thus preventing the automotive parts from moving during welding and affecting the welding quality.

[0014] 2. This utility model combines a dual-axis motor, a drive gear, and a driven gear. By starting the dual-axis motor and engaging the drive gear with the driven gear, two welded automotive parts are driven to rotate synchronously. This facilitates welding the reverse side of the automotive parts. Because the two automotive parts rotate synchronously, it avoids the weld on the front side from detaching when welding the reverse side of the automotive parts.

[0015] 3. This utility model combines a nut, a screw, a base plate, and a clamping plate. By tightening the nut and clamping plate, it is easy to hold automotive parts together. Since nuts are provided on both sides of the screw, the welded automotive parts can be easily and quickly disassembled by tightening the bolts after the reverse side of the automotive parts has been welded.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A welding frame for automotive welding production, see [link / reference] Figures 1 to 4 The system includes a U-shaped frame 1, with connecting shafts 2 rotatably connected to both sides of the inner cavity of the U-shaped frame 1. Both connecting shafts 2 pass through and are positioned on the outer side of the U-shaped frame 1. Connecting plates 21 are mounted on opposite ends of both connecting shafts 21. Connecting seats 22 are mounted on both sides of opposite ends of both connecting plates 21. Support rods 23 are rotatably connected to the inner sides of the four connecting seats 22 via rotating shafts. Cylinders 24 are mounted in the middle of opposite ends of both connecting plates 21. Baffles 3 are provided at the driving ends of both cylinders 24. Each baffle 3 has a rectangular groove 25 near the cylinder 24. The upper and lower ends of the inner cavities of the two rectangular grooves 25 are provided with sliding grooves 27. Two sliders 28 are slidably connected within each of the four sliding grooves 27. Pins 26 are fixedly connected between the upper and lower sliders 28 within the rectangular grooves 25 on the same side. One end of the support rod 23 is rotatably connected to the outside of the pin 26. A clamping mechanism is provided at the opposite end of each of the two baffles 3. A driving mechanism is provided at the outer end of each of the two connecting shafts 2. The driving mechanism includes a... The driven gear 62 is mounted on one end of the two connecting shafts 2 and the dual-axis motor 6 is mounted on the bottom of the U-shaped frame 1. Both drive ends of the dual-axis motor 6 are equipped with drive gears 61, which mesh with the two driven gears 62 respectively. During operation, the automotive parts to be welded are mounted on the clamping mechanisms on both sides. Then, the cylinder 24 is activated in conjunction with the support rod 23 to push the two clamped parts closer to each other and into contact. This ensures that the welding position of the clamped automotive parts is unobstructed, making it easier for personnel to weld the sides of the automotive parts. Furthermore, the two automotive parts are pressed and contacted during welding, thus preventing the automotive parts from moving and affecting the welding quality. By activating the dual-axis motor 6 and engaging the drive gears 61 and driven gears 62, the two automotive parts to be welded are driven to rotate synchronously, facilitating welding on the reverse side of the automotive parts. Because the two automotive parts rotate synchronously, it prevents the weld on the front side from detaching when welding the reverse side of the automotive parts.

[0023] For details, see Figure 3 The clamping mechanism includes a base plate 38 installed at one end of two baffles 3. Adjustment grooves 31 are provided on both sides of the opposite end of the two baffles 3. Adjustment blocks 32 are slidably connected in the two adjustment grooves 31 on the same side. A clamping plate 33 is connected between the two adjustment blocks 32 on the same side. A screw 34 passes through the clamping plate 33 and the base plate 38 on the same side. Nuts 35 are threaded on the outside of the screw 34 above the clamping plate 33 and the screw 34 below the base plate 38. By turning the nuts 35 in conjunction with the clamping plate 33, it is easy to clamp the automotive parts. Since nuts 35 are provided on both sides of the screw 34, the welded automotive parts can be easily and quickly disassembled by turning the bolts after the reverse welding of the automotive parts is completed.

[0024] Further, see Figure 1 The top of the U-shaped frame 1 is equipped with a light shield 4, which is hinged to the U-shaped frame 1. When welding automotive parts, the light shield 4 is rotated by the hinge to shield the welding area, thereby preventing the strong light generated by welding from causing damage to the eyes of personnel.

[0025] It is worth noting that, see Figure 1 Both sides of the U-shaped frame 1 are equipped with protective covers 5, and the protective covers 5 are transparent covers. The protective covers 5 not only increase the aesthetics of the device, but also prevent the rotation of the drive gear 61 from causing injury to personnel.

[0026] It is worth mentioning that, see Figure 3 Both ends of the screw 34 are fixedly connected to the limiting plate 37, and the size of the limiting plate 37 is larger than the size of the screw 34. By setting the limiting plate 37, the nut 35 is prevented from detaching from the screw 34 and being lost.

[0027] It is worth mentioning that, see Figure 3 Rubber pads 36 are installed on the opposite ends of the clamping plate 33 and the base plate 38. The rubber pads 36 are elastic. By setting the rubber pads 36, not only is the friction between the automotive parts and the clamping plate 33 and the base plate 38 increased, thereby improving the stability of the automotive parts, but also the wear of the automotive parts caused by direct contact with the base plate 38 and the clamping plate 33 during the clamping process is avoided.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
