[0001] The utility model relates to the technical field of roof frame welding, in particular to a roof frame assembly welding tool. Background Art

[0002] The roof frame usually refers to the structural frame of the car roof. It is part of the body frame and is used to support the shape and weight of the roof and provide overall stability and structural strength of the body. The roof frame is usually made of steel or aluminum alloy, with sufficient strength and rigidity to withstand the vibration and external pressure of the vehicle while maintaining the shape and stability of the body. In order to ensure that the parts do not move or twist during the welding process, thereby ensuring the welding quality and accuracy, the roof frame welding tooling is required.

[0003] However, during the use of traditional roof frame welding tooling, there is a certain gap between the workpiece and the mold, and during welding, there is a certain wear between the workpiece and the mold, resulting in damage to the workpiece surface. Therefore, in order to solve the above problems, a roof frame welding tooling is proposed. Summary of the invention

[0004] In order to make up for the above shortcomings, the utility model provides a roof frame assembly welding tool, which aims to improve the problem that a certain amount of wear will occur between the workpiece and the mold, resulting in damage to the workpiece surface.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 4 , the utility model provides an embodiment: a roof frame assembly welding tool, including a template 1, a rib plate 6 is fixedly connected inside the template 1, a workpiece 7 is arranged on the top of the template 1, an inner pad 8 is fixedly connected to the top of the workpiece 7, a connecting component is arranged between the workpiece 7 and the inner pad 8, fixing columns 2 are arranged on both sides of the template 1, a fixing ear 3 is fixedly connected to one side of the fixing column 2, and one side of the fixing ear 3 is fixedly connected to the outer wall of the template 1, an outer pad 9 is arranged on the top of the template 1, and the connecting component includes a countersunk screw 15, the outer wall of the countersunk screw 15 is threadedly connected to the inside of the template 1, and the workpiece 7 and the inner pad 8 are connected to the template 1 through the countersunk screw 15;

[0029] Specifically, first, the operator needs to accurately fit the workpiece 7 and the inner pad 8 on the template 1. This step seems simple, but it requires the operator to have rich experience and careful observation. The fit between the workpiece 7 and the inner pad 8 directly affects the subsequent fixing effect and the accuracy of the final product. In order to ensure the best fit, the operator usually uses a special fixture or positioning tool to assist the operation. Next, the workpiece 7 needs to be fixed to the inner pad 8 and the template 1 by a countersunk screw 15. The design of the countersunk screw 15 allows its head to sink into the surface of the workpiece 7, which not only ensures the firmness of the fixation, but also avoids the influence of the screw head on the appearance of the workpiece 7. During the fixing process, the operator needs to ensure that each screw is evenly stressed to avoid deformation or damage of the workpiece 7 due to uneven force. Finally, the template 1 is supported and fixed by the fixing column 2. The stability and load-bearing capacity of the fixing column 2 are directly related to the reliability of the fixation of the entire workpiece 7. Therefore, when selecting the fixing column 2, it is necessary to ensure that its material, size and load-bearing capacity meet the process requirements. At the same time, the layout of the fixing column 2 also needs to take into account the shape and weight distribution of the workpiece 7 to ensure that the workpiece 7 will not deviate or tilt during the fixing process.

[0030] Reference Figure 1-Figure 3 The top of the template 1 is fixedly connected with a clamping plate 10, and the side beam clamping device 4 is rotatably connected inside the clamping plate 10. A pin 12 is penetrated inside the clamping plate 10 and the side beam clamping device 4, and a flat washer 13 is provided on the outer wall of the pin 12. A cotter pin 14 is provided inside the pin 12. A plug column 11 is penetrated inside the side beam clamping device 4 and the clamping plate 10. A clamping screw 5 is fixedly connected to one end of the side beam clamping device 4, and the bottom of the outer pad 9 is attached to the outer wall of the inner pad 8;

[0031] Specifically, when welding is required, we first accurately place the outer pad 9 on the template 1 to ensure that its position is stable. Next, we gently turn the side beam clamp 4 downward to gradually approach the outer pad 9. In this process, the clamping plate 10 and the side beam clamp 4 are closely connected through the pin 12 to form a stable structure together. In order to ensure that the connection between the side beam clamp 4 and the clamping plate 10 is more secure, we insert the cotter pin 14 into the inside of the pin 12 to limit it. In this way, even if vibration or impact force is generated during the welding process, the side beam clamp 4 will not easily loosen or move. Subsequently, in order to fix the outer pad 9, we insert the plug 11 into the gap between the side beam clamp 4 and the clamping plate 10. This simple step not only effectively prevents the relative rotation between the side beam clamp 4 and the clamping plate 10, but also enhances the stability of the entire structure. Finally, we tighten the clamp screw 5 to fix it tightly on the outer pad 9. In this way, the outer pad 9 is firmly fixed on the template 1, providing stable support for the subsequent welding work.

[0032] Working principle: When using the roof frame welding fixture, first place the workpiece 7 and the inner pad 8 on the template 1, then fix the workpiece 7, the inner pad 8 and the template 1 with countersunk screws 15, and then support and fix the template 1 with the fixing column 2. When welding is needed, just place the outer pad 9 on the template 1, then rotate the side beam clamp 4 downward, and connect the side beam clamp 4 with the clamp 10 through the pin 12, and then insert the cotter pin 14 into the pin 12 to limit the pin 12. When fixing the outer pad 9, insert the column 11 into the side beam clamp 4 and the clamp 10 to fix it, place the side beam clamp 4 and the clamp 10 to rotate, and then tighten the clamp screw 5 to fix the outer pad 9, and then weld.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
