[0002] A suspension arm is a component used in a locomotive braking system. Its function is to effectively transmit and distribute the various forces on the wheels to the vehicle body, thereby ensuring that the wheels can follow a specific trajectory. In this process, the suspension arm provides a certain degree of support for the locomotive braking system.

[0003] like Figures 1-2 The diagram shows a suspension arm for a locomotive braking system, comprising a U-shaped main pipe A, two U-shaped plates B, a base plate C, a horizontal ear plate D, a U-shaped frame E, and two plugs F. The U-shaped main pipe A has an opening facing forward. The two vertical arm plates B-1 of the U-shaped plates B have corresponding through holes penetrating the plate body. One U-shaped plate B passes through the through holes on the two vertical arm plates B-1 and is welded and fixed to the left arm tube end of the U-shaped main pipe A. The other U-shaped plate B passes through the through holes on the two vertical arm plates B-1 and is welded and fixed to the right arm tube end of the U-shaped main pipe A. The upper surface of the base plate C has a concave... The base plate C is fitted and welded to the lower side of the top pipe of the U-shaped main pipe A through a groove on its upper end face; the U-shaped frame E is snapped and welded to the top pipe of the U-shaped main pipe A from front to back through two support arms E-1 located on the upper and lower sides, and the U-shaped frame E is adjacent to the right side of the base plate C; the two plugs F are correspondingly plugged and welded to the two ends of the U-shaped main pipe A; the right end of the horizontal ear plate D is vertically welded to the left side of the base plate C; the top corner of the U-shaped plate B, the corner of the base plate C, the left end of the horizontal ear plate D, and the vertical top plate of the U-shaped frame E on the front side are all provided with mounting holes that penetrate the plate body. Traditional welding methods for suspension arms often involve manual temporary assembly followed by direct welding. Therefore, the finished product is inevitably significantly affected by human factors during assembly, leading to the following problems: (1) poor positioning accuracy during assembly, making it difficult to ensure that each welded product meets requirements, resulting in inconsistent product quality; (2) low welding efficiency due to manual assembly, failing to meet the demands of large-volume delivery. To address these issues, this invention proposes a welding device for suspension arms in locomotive braking systems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a welding device for suspension arms in locomotive braking systems. This device significantly reduces the difficulty of splicing and positioning various components on the U-shaped main pipe, and improves the tightness of the weld joints between the components and the U-shaped main pipe. It effectively solves the problem of poor positioning accuracy in manual splicing, ensuring both the structural stability and shape accuracy of the welded suspension arm, thus helping to improve the product quality and finished product qualification rate. Compared with traditional manual splicing and welding methods, this device greatly reduces the welding difficulty of the suspension arm, thereby significantly improving welding efficiency, meeting the needs of large-volume delivery, and offering good economic practicality.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a welding device for a suspension arm in a locomotive braking system, comprising a base plate. A support assembly 1 for positioning and supporting a U-shaped plate located on the left side of the upper surface of the base plate is fixedly disposed at the left front corner. A support assembly 2 for positioning and supporting a U-shaped plate located on the right side of the suspension arm in the locomotive braking system is correspondingly fixedly disposed at the right front corner of the upper surface of the base plate. A pad 1 for positioning and supporting the upper bottom plate of the suspension arm in the locomotive braking system and a pad 2 for positioning and supporting the upper horizontal ear plate of the suspension arm in the locomotive braking system are disposed on the rear side of the middle portion of the upper surface of the base plate. A vertical plate 1 for positioning and supporting the U-shaped frame of the suspension arm in the locomotive braking system is also disposed in the middle portion of the upper surface of the base plate.

[0006] This utility model discloses a welding device for suspension arms in locomotive braking systems. During use, it significantly reduces the difficulty of assembling and positioning various components on the U-shaped main pipe, and improves the tightness of the weld joints between the components and the U-shaped main pipe. This effectively solves the problem of poor positioning accuracy in manual assembly, ensuring both the structural stability and shape precision of the welded suspension arm, thus contributing to improved product quality and finished product qualification rate. Compared to traditional manual assembly and welding methods, it greatly reduces the welding difficulty of the suspension arm, thereby significantly improving welding efficiency, meeting the needs of large-volume deliveries, and offering good economic practicality.

[0007] The preferred technical solution is that the support component one includes a support block, a vertical plate two, and a vertical plate three. The vertical plate two is adjacent to the left side of the support block, and the vertical plate three is adjacent to the right side of the support block. The heights of both the vertical plate two and the vertical plate three are greater than the height of the support block. The three components together form a groove for threading through the end of the left arm tube of the U-shaped main tube on the suspension arm of the locomotive braking system. The upper end face of the vertical plate two has a stepped groove with an opening facing the upper right. The horizontal bottom surface of the stepped groove is flush with the upper end face of the vertical plate three. The horizontal bottom surface of the stepped groove and the upper end face of the vertical plate three are both provided with positioning holes one. The positioning holes one correspond one-to-one with the mounting holes on the top plate of a U-shaped plate on the left side of the suspension arm in the locomotive braking system.

[0008] The second support component and the first support component are mirror images of each other.

[0009] The upper left end of the pad block 2 is provided with a positioning hole 3, which corresponds to the mounting hole at the left end of the horizontal ear plate on the suspension arm in the locomotive braking system;

[0010] The upper end of the vertical plate is provided with several positioning holes four that penetrate the plate body, and the positioning holes four correspond one-to-one with the mounting holes on the vertical top plate of the U-shaped frame on the suspension arm of the locomotive braking system. The support component one and support component two have ingenious and reasonable structural designs, ensuring the convenience and efficiency of the U-shaped plate when it is inserted and positioned at the end of the arm tube of the U-shaped main tube.

[0011] A further preferred technical solution includes a plurality of positioning holes 2 on the upper end face of the pad block 1, each positioning hole 2 corresponding to a mounting hole on the upper base plate of the suspension arm in the locomotive braking system; a backing plate 1 for positioning the middle part of the upper top tube of the U-shaped main pipe is fixedly provided on the rear side of the upper end face of the pad block 1. When the base plate is installed on the upper end face of the pad block 1, positioning pins can be inserted one-to-one with the mounting holes 2 on the base plate and the positioning holes 2 on the pad block 1 to ensure the installation stability of the base plate on the pad block 1, thereby ensuring the assembly accuracy between the base plate and the U-shaped main pipe; the backing plate 1 provided on the rear side of the upper end face of the pad block 1 helps to further reduce the positioning difficulty of the base plate during assembly on the upper end face of the pad block 1.

[0012] A further preferred technical solution includes a third pad for supporting the middle of the right side section of the upper top tube of the U-shaped main pipe at the right end of the upper surface of the substrate, and a fourth pad for supporting the middle of the left side section of the upper top tube of the U-shaped main pipe at the left end of the upper surface of the substrate. The third pad supports the middle of the right side section of the upper top tube of the U-shaped main pipe, and similarly, the fourth pad supports the middle of the left side section of the upper top tube of the U-shaped main pipe, further improving the stability of the U-shaped main pipe when placed on the welding equipment of this invention.

[0013] A further preferred technical solution is that a second backing plate is fixedly provided on the front end of the upper side of the pad block three for positioning and supporting the middle of the right side section of the upper jacking pipe of the U-shaped main pipe. During the welding of the U-shaped frame to the U-shaped main pipe, the second backing plate plays a limiting and heat-conducting role on the part of the right side section of the upper jacking pipe of the U-shaped main pipe adjacent to the right side of the U-shaped frame, thereby effectively reducing the deformation of the right side section of the upper jacking pipe of the U-shaped main pipe when heated during welding, which helps to improve the shape accuracy of the finished cantilever arm.

[0014] A further preferred technical solution is that positioning pins are installed inside positioning holes one, two, three, and four. When each component is placed on its corresponding pad, the mounting holes on the component and the positioning holes on the corresponding pad are connected by the positioning pins, ensuring the installation stability of each component on the pad. This helps to further reduce displacement deformation during welding, thereby helping to further improve the shape accuracy of the finished cantilever arm.

[0015] A further preferred technical solution is that the substrate is a U-shaped plate structure with the opening facing forward, the first support component is located at the front end of the left leg plate of the substrate, the second support component is located at the front end of the right leg plate of the substrate, and the first pad, the second pad, the first vertical plate, the third pad, and the fourth pad are all located on the top plate of the substrate.

The upper surface of the pad block one is provided with several positioning holes two, which correspond one-to-one with the mounting holes on the bottom plate of the suspension arm in the locomotive braking system; a backing plate one for positioning the middle of the top tube of the U-shaped main pipe is fixed on the rear side of the upper surface of the pad block one.
