Description

Technical Field

[0001] The utility model relates to the technical field of railway flat cars, in particular to an assembly tool used for auxiliary beam components of railway flat cars. Background Art

[0002] The auxiliary beams of the NX70 shared flat car consist of components such as longitudinal beams, small cross beams, longitudinal beam ribs, small cross beam ribs, fireproof panels, and fireproof panel supports. In the actual assembly process, the longitudinal beams and small cross beams are assembled by combining mold positioning with manual marking, and the longitudinal beam ribs and small cross beam ribs are assembled by manual marking. Since the weight of the longitudinal beams and small cross beams ranges from 10 to 30 kg, 2 to 3 people are required to work together. During marking and assembly, the workers' workload is high, and the coordination of multiple people is prone to large assembly errors, resulting in misalignment and tilted installation of the small cross beams and longitudinal beams, increasing the amount of subsequent rework. When assembling the ribs, due to limited operating space, some positions can only be assembled visually, resulting in a higher proportion of skewed ribs.

[0003] A Chinese invention patent application with publication number CN113042963A discloses a method and device for assembling and positioning wooden clamps for a flat car, which addresses quality issues such as skew and dimensional deviation that occur after welding wooden clamps in the prior art. The method comprises: placing each positioning sample rod at the welding position of the wooden clamps on the chassis of the flat car, wherein the positioning sample rod comprises a connecting rod and one or more positioning and fixing assemblies with a clamping cavity mounted on the connecting rod; placing one end of the connecting rod of the positioning sample rod located on the outermost longitudinal side against the crossbeam of the chassis to achieve longitudinal positioning of the positioning sample rod; clamping the positioning sample rod near the beam of the chassis to the corresponding beam via a transverse positioning plate to achieve transverse positioning of the positioning sample rod; and inserting each wooden clamp into the clamping cavity of the corresponding positioning sample rod to complete the welding and positioning of the wooden clamp. This solution can accurately position the wooden clamps through the positioning and fixing assemblies, improve the efficiency of wooden clamp welding, ensure normal production rhythm, and effectively control the welding deformation of the wooden clamps. Since this solution cannot simultaneously position the longitudinal beam, small cross beam, longitudinal beam reinforcement plate, small cross beam reinforcement plate, etc., it needs further improvement.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1As shown, an embodiment of the utility model provides an assembly tool for the auxiliary beam assembly of a railway flat car, including a longitudinal beam assembly component 100, a longitudinal beam stiffener assembly component 200, and a small crossbeam and stiffener assembly component 300, which are correspondingly arranged at corresponding positions of the middle beam 4, the side beam 5 or the large crossbeam 6.

[0027] The beam assembly component 100 is as follows Figure 2 As shown, it is a longitudinal beam support plate 101, which is formed as a whole by cutting. In order to ensure that the longitudinal beam 7 can be accurately positioned, two longitudinal beam support plates 101 are used at a certain distance to jointly support and position the longitudinal beam 7. The two lower end faces of the longitudinal beam support plates 101 are respectively placed on the upper wing edges of the middle beam 4 and the upper wing edges of the side beam 5, and the lower plane and C-shaped opening surface of the longitudinal beam 7 are respectively fitted with the corresponding positioning surfaces on the longitudinal beam support plates 101. The gap between the longitudinal beam 7 and the large crossbeam 6 is adjusted, and the longitudinal beam 7 is fixed by spot welding before the longitudinal beam support plates 101 are removed.

[0028] like Figure 3 As shown, the longitudinal beam reinforcement plate assembly component 200 includes a first base plate 201, a first connecting plate 202, a second connecting plate 203, a first positioning plate 204, a second positioning plate 205, a (NdFeB) first magnet 206, a first positioning arm 207, and a first reinforcing plate 208. The overall structure is connected by welding, and the connection position of the first magnet 206 is not welded.

[0029] Among them, a pair of first positioning arms 207 are provided, and the first end of the first positioning arm 207 passes through the second connecting plate 203 and is connected to the first connecting plate 202. The second ends of the first positioning arms 207 are connected to the first reinforcing plate 208 to increase the rigidity of the structure. At the same time, the second end of the first positioning arm 207 is formed with a bend to hook the cover plate of the large crossbeam 6, acting as a fixing component. The side surface of the first positioning arm 207 is in contact with the longitudinal beam 7 to ensure the lateral positioning size of the longitudinal beam reinforcement plate 8. The first connecting plate 202 and the second connecting plate 203 are connected to the first bottom plate 201, and the first positioning plate 204 and the second positioning plate 205 are both connected between the first connecting plate 202 and the second connecting plate 203 to form an overall frame structure. The first magnet 206 is installed between the corresponding first positioning plate 204 and the second positioning plate 205 to adsorb the longitudinal beam reinforcement plate 8. The first magnet 206 is covered by the second positioning plate 205 to prevent the first magnet 206 from breaking and falling or being adsorbed on the longitudinal beam reinforcement plate 8 during evacuation.

[0030] like Figure 4As shown, the small crossbeam and rib assembly 300 is similar in structure to the longitudinal beam and rib assembly 200, comprising a second base plate 301, a third connecting plate 302, a fourth connecting plate 303, a third positioning plate 304, a fourth positioning plate 305, a second (NdFeB) magnet 306, and a second positioning arm 307. The entire assembly is welded together, with the second magnet 306 being unwelded.

[0031] A pair of second positioning arms 307 are provided for the small crossbeam and rib assembly component 300, and the first end of the second positioning arm 307 passes through the rear side of the fourth connecting plate 304 and is connected to the second bottom plate 301. The side surface of the second positioning arm 307 fits with the open surface of the small crossbeam 9 to ensure the lateral dimension of the small crossbeam 9. The second reinforcing plate 308 is provided on the upper surface of the third connecting plate 302 and is connected to the inner side surfaces of the two second positioning arms 307 to strengthen the structural rigidity. The fourth connecting plate 303 is installed on the bent inner side surface of the second positioning arm 307, fits with the upper plane of the side beam 5 or the middle beam 4 through the fourth connecting plate, and fixes the two by a clamp to fix the entire assembly. The third positioning plate 304 and the fourth positioning plate 305 are connected to the second bottom plate 301. The second magnet 306 is installed between the corresponding third positioning plate 304 and the fourth positioning plate 305 to adsorb the small crossbeam rib 10. At the same time, the second magnet 306 is covered by the fourth positioning plate 305 to prevent the second magnet 306 from breaking and falling or adsorbing on the small crossbeam rib 10 during evacuation. When assembling the small crossbeam 9, two sets of components are used, one of which is fixed to the upper plane of the middle beam 4 and the other is fixed to the upper plane of the side beam 5, to jointly support the small crossbeam 9. When assembling the small crossbeam rib 10, it can be assembled separately using the two sets of components.

[0032] Therefore, through the tooling provided in this embodiment, the assembly of the longitudinal beam 7, the longitudinal beam reinforcement plate 8, the small cross beam 9 and the small cross beam reinforcement plate 10 can be completed in sequence, and the positioning can be performed directly through the tooling, avoiding the problems of misalignment and tilted installation caused by the original marking positioning and visual assembly, which not only improves production efficiency and quality, but also reduces the labor intensity of operators.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
