Description

Technical Field

[0001] This utility model relates to the field of vehicle body side panel welding technology, and in particular to a vehicle body side panel welding positioning fixture that can be used by multiple vehicle models. Background Technology

[0002] Side panel welding refers to the manufacturing process in automobile body manufacturing in which welding technology is used to connect the various components of the side panel, including the outer and inner panels, pillars, sills, wheel arches, and the side panel assembly, to other parts of the vehicle body to form a complete and robust side structure unit. Its core function is to build the basic framework of the side of the vehicle body and ensure the structural strength and rigidity of the side panel.

[0003] However, existing body side panel welding positioning fixtures have the following drawbacks: traditional mechanical clamping, such as hydraulic clamping, is prone to leaving indentations on the sheet metal surface of thin plates. Furthermore, during the welding process, when the welding heat is conducted to the fixture, it is easy to cause the metal to expand and deform due to heat, resulting in unstable clamping and affecting the welding accuracy of the body side panel. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a vehicle body side panel welding positioning fixture that can be used by multiple vehicle models. It solves the technical problems of traditional mechanical clamping, such as hydraulic clamping, which easily leaves indentations on the sheet metal surface of thin plates, and the fact that during the welding process, when the welding heat is conducted to the fixture, it easily causes the metal to expand and deform due to heat, resulting in unstable clamping and affecting the welding accuracy of the vehicle body side panel.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-vehicle body side panel welding and positioning fixture includes a positioning frame and a body side panel component. The body side panel component is located at the side end of the positioning frame. The positioning frame is provided with a fixing mechanism for fixing the body side panel component. The fixing mechanism includes a fixing base, a negative pressure fixing head, a suction pipe, and a cooling chamber. The fixing base is fixedly installed at the side end of the positioning frame. The negative pressure fixing head is located at the side end of the fixing base. The cooling chamber is located on the outer wall of the negative pressure fixing head. A cylinder is fixedly installed at the side end of each fixing base. A universal joint is fixedly installed at the side end of each cylinder. The negative pressure fixing head is fixedly installed at the side end of each universal joint. A suction hole is opened on the inner wall of the negative pressure fixing head. The suction pipe is fixedly installed on the inner wall of the suction hole.

[0008] Preferably, each of the cooling chambers is fixedly installed at the circumferential end of the negative pressure fixing head.

[0010] Compared with the prior art, the present invention has the following beneficial effects.

[0011] I. This device uses a negative pressure fixing head to fix the side panel of the vehicle body by negative pressure adsorption. The resulting adsorption force is evenly distributed, which can effectively avoid surface indentation caused by mechanical pressure head, and maintain the integrity of the side panel of the vehicle body while maintaining a stable fixation.

[0012] Second, this device is equipped with a cooling box and a cooling chamber.

[0019] This application provides a multi-vehicle body side panel welding positioning fixture, which effectively solves the problems of traditional mechanical clamping, such as hydraulic clamping, which easily leaves indentations on the sheet metal surface of thin plates. Furthermore, during the welding process, when the welding heat is conducted to the fixture, it easily causes the metal to expand and deform due to heat, resulting in unstable clamping and affecting the welding accuracy of the body side panel 6. This device is equipped with a negative pressure fixing head 3, which fixes the body side panel 6 by negative pressure adsorption. The adsorption force generated is evenly distributed, which can effectively avoid surface indentation caused by mechanical pressure heads and maintain the integrity of the body side panel 6 while maintaining a stable fixation.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution described in this application effectively solves the problems of traditional mechanical clamping, such as hydraulic clamping, which easily leaves indentations on the sheet metal surface of thin plates. Furthermore, during welding, the heat from welding is easily conducted to the clamp, causing the metal to expand and deform, leading to unstable clamping and affecting the welding accuracy of the vehicle side panel 6. The overall concept is as follows: A multi-vehicle vehicle side panel welding and positioning fixture includes a positioning frame 1 and a vehicle side panel 6. The vehicle side panel 6 is located at the side end of the positioning frame 1. The positioning frame 1 is provided with a fixing mechanism for fixing the vehicle side panel 6. The fixing mechanism includes a fixing base 2, a negative pressure fixing head 3, a suction pipe 4, and a cooling chamber 5. The fixing base 2 is fixedly installed at the side end of the positioning frame 1, the negative pressure fixing head 3 is located at the side end of the fixing base 2, and the cooling chamber 5... A cylinder 21 is fixedly installed on the side end of each fixed base 2 on the outer wall of the negative pressure fixing head 3. A universal joint 22 is fixedly installed on the side end of each cylinder 21. Each negative pressure fixing head 3 is fixedly installed on the side end of the universal joint 22. A suction hole 31 is opened on the inner wall of the negative pressure fixing head 3. A suction pipe 4 is fixedly installed on the inner wall of the suction hole 31. When the body side panel 6 is welded, it needs to be positioned and clamped. In this device, the end of each suction pipe 4 is connected to the distributor on the air pump. The controller receives input parameters, such as the adsorption force setting value, and starts the air pump to generate compressed air. The compressed air drives the distributor to draw each independent suction pipe 4 into a negative pressure state. The negative pressure fixing head 3 integrated at the end of the suction pipe 4 will form a negative pressure adsorption force on the sheet metal surface of the body side panel 6.

[0022] Each cooling chamber 5 is fixedly installed at the circumferential end of the negative pressure fixing head 3. The lower end of the cooling chamber 5 is fixedly installed with a cooling pipe 51 and a return pipe 52. The user can start the suction pump and use the suction pump and the distributor to pump the coolant in the cooling box 11 into the negative pressure fixing head 3 through the cooling pipe 51. The coolant in the negative pressure fixing head 3 cools the cooling chamber 5, avoiding the high temperature generated during the welding of the body side panel 6, which may cause the negative pressure fixing head 3 to be adsorbed and deformed. The coolant can be returned to the cooling box 11 through the return pipe 52, in the existing welding clamping and positioning of the body side panel 6.

[0023] Each cooling pipe 51 and return pipe 52 is fixedly installed inside the cooling box 11. During the welding process, the temperature of the local body side panel 6 will be high. In this device, a suction pump is installed inside the cooling box 11, and a distributor is installed on the suction pump. The end of each cooling pipe 51 is connected to the distributor on the suction pump.

[0024] To address the problems existing in the prior art, this utility model provides a vehicle side panel welding and positioning fixture that can be used by multiple vehicle models. This device is equipped with a negative pressure fixing head 3, which fixes the vehicle side panel 6 by negative pressure adsorption. The adsorption force generated is evenly distributed, which can effectively avoid surface depression caused by mechanical pressure head, and maintain the integrity of the vehicle side panel 6 while maintaining a stable fixation.

[0025] Working principle:

[0026] When welding the body side panel 6, positioning and clamping are required. In this device, the end of each suction tube 4 is connected to a distributor on the air pump. The controller receives input parameters, such as the suction force setting value, and starts the air pump to generate compressed air. The compressed air drives the distributor to draw each independent suction tube 4 into a negative pressure state. The negative pressure fixing head 3 integrated at the end of the suction tube 4 forms a negative pressure suction force on the sheet metal surface of the body side panel 6, thereby fixing the body side panel 6. Simultaneously, during the welding process, local body panels... The side panel 6 generates high temperatures. In this device, a suction pump is installed inside the cooling tank 11, and a distributor is mounted on the suction pump. The end of each cooling pipe 51 is connected to the distributor on the suction pump. The user can start the suction pump, and through the pump and distributor, the coolant in the cooling tank 11 is pumped into the negative pressure fixing head 3 via the cooling pipes 51. The coolant in the negative pressure fixing head 3 cools the cooling chamber 5, preventing the negative pressure fixing head 3 from being deformed due to the high temperatures generated during the welding of the side panel 6. The liquid can be returned to the cooling tank 11 through the return pipe 52. In the existing welding clamping and positioning of the body side panel 6, traditional mechanical clamping such as hydraulic clamping is prone to leaving indentations on the sheet metal surface of thin plates. Moreover, during the welding process, when the welding heat is conducted to the clamp, it is easy to cause the metal to expand and deform due to heat, resulting in unstable clamping and affecting the welding accuracy of the body side panel 6. This device is equipped with a negative pressure fixing head 3, which fixes the body side panel 6 by negative pressure adsorption. The adsorption force generated is evenly distributed, which can effectively avoid the surface indentation caused by mechanical pressure head. While maintaining the stability of the fixation, it maintains the integrity of the body side panel 6. In addition, this device is equipped with a cooling tank 11 and a cooling chamber 5. The coolant in the cooling tank 11 is drawn into the cooling chamber 5 to remove the heat on the negative pressure fixing head 3. This can prevent the negative pressure fixing head 3 from being deformed by heat conduction during welding, which would affect the adsorption and fixation of the body side panel 6. This ensures the stability of the fixation of the negative pressure fixing head 3 on the body side panel 6 and improves the welding accuracy of the body side panel 6.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
