The railway vehicle traction beam assembling and welding tool comprises a frame (1), workpiece clamping assemblies and welding base plate clamping assemblies, wherein the workpiece clamping assemblies and the welding base plate clamping assemblies are arranged on the frame (1). The workpiece clamping assemblies areused for clamping and fixing workpieces (6) and comprise cantilever clamping mechanisms (2) and supporting assemblies (3), and the cantilever clamping mechanisms (2) and the supporting assemblies (3)are arranged in a one-to-one correspondence mode. The welding base plate clamping assemblies are used for clamping welding base plates (7) to back welding seams of the workpieces (6) and comprise welding base plate pressing mechanisms (4). The railway vehicle traction beam assembling and welding tool comprises at least one set of workpiece clamping assembly and at least one set of welding base plate clamping assembly which are arranged on the frame, clamping of the workpieces is achieved through the workpiece clamping assemblies, the welding base plates are clamped at the back welding seams of the workpieces through the welding base plate clamping assemblies, and the welding process requirement of the workpieces is met.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a welding tool for assembly and welding of a traction beam of an underframe of a rail vehicle. Background technique [0002] In the machinery manufacturing industry, the main body of a rail vehicle is usually composed of an underframe, side walls, end walls and a roof; The traction beam of the chassis is the installation interface of the vehicle traction device and the direct transmission part of the traction force. The quality of the traction beam will directly affect the performance and driving safety of the rail vehicle. The traction beam is the most important key component. [0003] In the manufacturing process of traction beams, the requirements for weld grade and dimensional accuracy are very high, and the manufacturing process requires very strict control.

Problems solved by technology

[0003] In the manufacturing process of traction beams, the requirements for weld grade and dimensional accuracy are very high, and the manufacturing process requires very strict control. The most important thing is to ensure the accuracy and stability of the welding process and the prevention and control of welding deformation. The drawbeam is clamped and fixed on the tooling connected with the turning positioner, and the welding robot is used for automatic welding; since the size of the drawbeam is different for different models, if special tooling is used, different types of drawbeams will be used in the production process. It is often necessary to replace tooling, which not only consumes time and manpower, but also increases the demand for tooling, and will also occupy a large tooling storage space and circulation resources

[0004] The existing tooling is basically a special tooling, the clamping and clamping group cannot be adjusted or the adjustment space is very small, it is basically not universal or the versatility is very poor, and the structure of the clamping group of the existing tooling is unreasonable, resulting in insufficient strength and inconvenient loading and unloading As a result, the failure rate of the tooling is extremely high, and the performance is very unreliable. However, the present invention provides a universal welding tooling for the traction beam of the rail vehicle chassis that can be quickly assembled and disassembled, has reliable performance, good versatility, and is easy to maintain.
