Description

TECHNICAL FIELD

[0001] The utility model belongs to welding frock technical field, specifically relates to a swing bolster wear plate automatic assembly welding system. BACKGROUND

[0002] The swing bolster is one of the key components of the running gear of the railway locomotive and vehicle, has the functions of bearing, buffering, shock absorption, keeping the stability and balance of the vehicle, is generally located at the central position of the bogie, is similar to the cuboid or has a certain arc block structure, and the main function of the swing bolster is to support the vehicle body and uniformly transmit the weight of the vehicle body to other components (such as spring devices) of the bogie. The side wall wear plate has position requirements in the horizontal and vertical directions, the inclined wear plate requires the center position of the two side wall wear plates, and has position requirements with the spring seat, so the inclined wear plate and the side wall wear plate are both the key components for prolonging the service life of the swing bolster.

[0003] 1. The inclined wear plate is usually located on the inclined surface of the swing bolster, and the inclined surface is generally designed to match the relative movement and force transmission between the bogie and the vehicle body during the running process of the vehicle. The shape of the wear plate is adapted to the specific geometric shape of the inclined surface of the swing bolster, and is usually a flat plate with a certain thickness, and the surface is relatively smooth, and some may be rectangular, and some may be irregularly shaped according to the specific installation position to fit the contour of the inclined surface of the swing bolster; the action principle of the inclined wear plate: when the vehicle runs, the inclined surface of the swing bolster will slide or rub with other components (such as wedges). Due to the complex running conditions of the train, including starting, braking and passing through curves, these actions will make the inclined surface of the swing bolster frequently bear the action force, and the inclined wear plate mainly plays the role of reducing friction and wear. It is like a "protective pad", when the inclined surface of the swing bolster interacts with the adjacent components, the wear plate bears the friction instead of the swing bolster body, avoids the inclined surface of the swing bolster from appearing serious surface wear due to long-term friction, and prolongs the service life of the swing bolster.

[0004] 2、Side wall wear plate is installed on the side wall of the bolster, the side wall of the bolster will contact and move relative to the surrounding components (such as side frame, etc.) during the operation of the vehicle, the shape of the wear plate will be designed according to the shape of the side wall of the bolster and the requirements of the contacting components, which is usually a long and thin plate, the length and width of which are determined according to the size of the side wall of the bolster and the required protection range, which can cover the key friction area of the side wall of the bolster. The principle of the side wall wear plate: during the operation of the vehicle, especially under various dynamic actions of the bogie, the side wall of the bolster will rub, collide and so on with the adjacent components, the main function of the side wall wear plate is to prevent the wear of the side wall of the bolster. For example, when the train passes through a curve, the side frame of the bogie may generate a lateral force on the side wall of the bolster, resulting in friction between them, the side wall wear plate can effectively transfer the wear caused by the friction to itself, protecting the structural integrity of the side wall of the bolster and ensuring the normal function of the bolster is not affected.

[0005] The inclined wear plate and the side wall wear plate are usually welded on the bolster in the assembly welding process, assembly welding is a short name for assembly welding, which is a process of assembling multiple parts together and then welding them, which is a widely used process in modern manufacturing industry, especially in many fields such as mechanical manufacturing, building steel structure, automobile manufacturing, shipbuilding, etc. The process steps of assembly welding mainly include: preparation (including cleaning of the welding surface, preparation of the parts) → assembly (positioning, fixing of the parts, position checking, etc.) → welding → cleaning (polishing the weld, removing the welding slag) → inspection. The bolster is a casting, so its dimensional accuracy is not high, the wear plate mounting surface is a casting blank surface, only simple polishing is performed, resulting in that the distance between the two side wall wear plate mounting surfaces is not a constant value, the two mounting surfaces are not completely parallel, and the distance and the included angle between the two inclined wear plate mounting surfaces are also not constant values. In the assembly welding process, the wear plate is manually fitted with the casting base surface, and the measuring tools and gauges are used for auxiliary positioning and detection, which can meet the installation requirements, but the process is complicated and the efficiency is low, most of the time is consumed in measurement and detection, the time for welding the weld is generally 20%~30% of the whole assembly welding process, and the rest is the time consumed for preparation, assembly, inspection and other auxiliary work, that is, the workload of the pre-welding preparation work and the post-welding auxiliary process often exceeds the workload of the welding itself. The current assembly welding of the inclined wear plate and the side wall wear plate is operated manually, the process is complicated and the efficiency is low, therefore, to improve the assembly welding efficiency, the most effective method is to design and optimize the tooling used for assembly welding, thereby reducing the time of auxiliary processes.
