[0002] As urban rail transit has begun to develop towards lightweight and high-speed in recent years, and as the operating speed increases, the load on the traction beam of the rail vehicle body has also greatly increased. The vehicle-end anti-climber energy absorption device is directly installed on the anti-climber mounting seat of the traction beam at the driver's cab end through bolts. The installation quality directly affects the vehicle appearance and operation safety. Therefore, the flatness control of the anti-climber mounting seat is particularly important.

[0003] The anti-climber is generally installed at the end of the driver's cab, but the manufacturing process of the traction beam at the driver's cab end is relatively complicated. After the anti-climber mounting seat is processed as a whole, it needs to be welded to the single-piece traction beam. Due to the special position of the anti-climber mounting seat and the large number of welds around it, the clamping device on the existing tooling platform cannot be fixed, resulting in serious deformation of the processed surface after welding and serious flatness deviation. Therefore, mechanical adjustment and flame adjustment are required for adjustment, which is labor-intensive and leads to low installation efficiency.

[0004] In summary, how to provide a tool for limiting the position of the anti-climber during the welding process is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The core of the utility model is to provide a rail vehicle body anti-climber mounting seat limiting tooling, which effectively controls welding deformation, reduces the amount of post-weld adjustment and repair, and ensures welding quality and subsequent anti-climber installation quality.

[0029] Please refer to Figure 1-Figure 3 A rail car body anti-climber mounting seat limiting tooling includes a mounting seat for installing an anti-climber. The mounting seat includes two mounting plates, two positioning plates, and are fixedly connected to the same plane of the two mounting plates respectively so that the two mounting plates remain in the same plane after welding. The two positioning plates are connected by a connecting rod, and the sides of the two positioning plates in contact with the mounting plates are in the same plane.

[0030] It should be noted that the number of mounting plates 2 and positioning plates 3 in the embodiment of the present invention is not fixed. Under the requirements of different vehicle models, the number of positioning plates 3 can be adjusted according to the number of different mounting plates 2, as long as the multiple positioning plates 3 are all in the same flatness.

[0031] When in use, the mounting seat 1 is used to install the anti-climber, and the mounting seat 1 is installed on the rail car body. Before welding, the mounting plate 2 and the positioning plate 3 are fixedly connected. The two positioning plates 3 are connected by a connecting rod 4. The two positioning plates 3 are in the same plane. During production, the two positioning plates 3 are trimmed after flatness detection to ensure that the two positioning plates 3 are in the same plane. At the same time, they are kept in fixed position under the action of the connecting rod 4. After the mounting plate 2 is connected to the positioning plate 3, the mounting plate 2 is welded. Since the two mounting plates 2 are in a rigidly fixed state under the action of the positioning plate 3 and the connecting rod 4, welding is performed in this state. After welding, the flatness of the anti-climber mounting surface is guaranteed, welding deformation is effectively controlled, the amount of adjustment is reduced, and the welding quality of the traction beam at the driver's cab end and the subsequent anti-climber installation quality are guaranteed.

[0032] Optionally, in some embodiments, the positioning plate 3 and the connecting rod 4 can be fixedly connected, for example, by welding, and a plurality of reinforcing ribs are provided at the connection to improve the firmness of the rigid fixation of the mounting plate 2 through the reinforcing ribs.

[0033] In other embodiments, in order to adapt to the use of mounting seats 1 of different sizes, strip-shaped grooves are provided on the positioning plate 3. Specifically, a groove formed by a U-shaped plate is installed on the positioning plate 3, and a number of protrusions extending along its length are provided inside the groove. A sliding groove corresponding to the protrusion is provided on the connecting rod 4. The connecting rod 4 slides inside the groove to adjust the distance between the two positioning plates 3, thereby making it adaptable to the use of mounting seats 1 of more sizes, thereby improving the versatility of the device.

[0034] Optionally, in some embodiments, the positioning plate 3 is provided with a plurality of through holes 301, and the through holes 301 are used to connect the positioning plate 3 and the mounting seat 1 through bolts. Specifically, the mounting plate 2 is provided with a plurality of bolt holes for fixing the anti-climber, so the through holes 301 on the positioning plate 3 are arranged according to positions corresponding to the bolt holes on the mounting plate 2. During installation, the positioning plate 3 and the mounting plate 2 are fixedly connected by bolts.

[0035] In other embodiments, in order to further adapt the device to the use of mounting plates 2 of more sizes, the through hole 301 on the positioning plate 3 can adopt a strip structure. Specifically, the through hole 301 is composed of multiple strip through holes 301 with different radii. Therefore, it can meet the use of mounting plates 2 of more sizes and improve the versatility of the device.

[0036] In other embodiments, a splint is further included. The splint is a U-shaped structure, and the positioning plate 3 is placed between the grooves. A locking bolt is provided on the positioning plate 3. The splint and the locking bolt are threaded together, and the splint is driven close to or away from the mounting plate 2 by the locking bolt. When in use, the mounting plate 2 is placed in the splint groove, and the locking bolt is used to achieve a tight fit between the positioning plate 3 and the mounting plate 2 by the splint to fix the position, and at the same time, it can be suitable for more sizes of mounting seats 1.

[0037] In order to make the device applicable to mounting seats 1 of more sizes, in some embodiments, the connecting rod 4 adopts a telescopic structure, that is, the distance between the two positioning plates 3 is adjusted by the telescopic connection rod 4, thereby ensuring that the two positioning plates 3 can adapt to mounting seats 1 of different sizes.

[0038] Optionally, in some embodiments, the connecting rod 4 may adopt a spline structure arranged along the telescopic direction to improve the rigid connection of the connecting rod 4 during the telescopic process.

[0039] Optionally, in order to enhance the connection rigidity of the connecting rod 4 during its extension and retraction process, in some embodiments, the connection positions of the two sections of the connecting rod 4 both adopt a W-shaped cross-section structure, and through cross-connection, a telescopic structure with higher connection strength is achieved.

[0040] In order to further improve the flatness of the mounting plate 2 after welding, in some embodiments, an adjusting member 5 is also included. The adjusting member 5 is located between the positioning plate 3 and the mounting seat 1, and is used to form a prefabricated welding reverse deformation of the mounting plate 2. Specifically, before welding, by placing the adjusting member 5 between the positioning plate 3 and the mounting seat 1, the thickness of the adjusting member 5 can make the mounting plate 2 tilt at a certain angle toward the mounting seat 1. After welding, it can just ensure that the two mounting plates 2 are in the same parallelism, quickly form a prefabricated welding reverse deformation, and further improve the flatness after welding.

[0041] Optionally, in some embodiments, the adjusting member 5 is a plate-shaped structure. Specifically, the adjusting member 5 is a stainless steel plate to ensure strong support during the welding process.

[0042] Optionally, in order to replace the adjusting member 5 with a different thickness, in some embodiments, the adjusting member 5 is detachably mounted on the positioning plate 3 , and the required adjusting member 5 can be quickly replaced by disassembly.

[0043] Optionally, in some embodiments, the adjusting member 5 can be fixed to the positioning plate 3 by providing a protrusion on the back side thereof and providing a corresponding groove on the positioning plate 3. When the protrusion is inserted into the groove, the adjusting member 5 is fixed to the positioning plate 3.

[0044] In other embodiments, a magnet may be provided at the edge of the adjusting member 5, and the thickness of the magnet may be lower than the thickness of the adjusting member 5. When in use, the adjusting member 5 only needs to be placed on the positioning plate 3 to realize the installation of the adjusting member 5, which is convenient and quick.

[0045] In order to enable the adjusting member 5 to produce reverse deformation at different angles and to adjust it quickly, in some embodiments, an adjusting rod is threadedly installed on the positioning plate 3, and the adjusting member 5 is connected to one end of the adjusting rod close to the mounting plate 2. That is to say, when it is necessary to adjust the width of the gap between the positioning plate 3 and the mounting plate 2 by the adjusting member 5, it is only necessary to rotate the adjusting rod, and through the threaded connection of the adjusting rod, the adjusting member 5 is moved away from the positioning plate 3, thereby achieving control of the width of the gap between the positioning plate 3 and the mounting plate 2, thereby satisfying that the adjusting member 5 can produce reverse deformation at different angles, and the adjustment method is simple, and it has high stability after the adjustment is completed.

[0046] In order to further improve the positioning effect of the mounting plate 2, in some embodiments, gears are installed on both adjusting rods, and the two adjustments are connected by a chain to achieve synchronous rotation. That is to say, the two adjusting rods are controlled by a chain to achieve synchronous rotation, so as to ensure that the two adjusting rods have the same control amount on the adjusting member 5, which is beneficial to ensure that the two mounting plates 2 are in the same horizontal position and improve the welding quality of the anti-climber mounting seat.

[0047] In order to further improve the positioning effect of the mounting plate 2, in some embodiments, a fixing mechanism is provided on the connecting rod 4, and the positions of the connecting rod 4 and the mounting seat 1 are relatively fixed by connecting the connecting rod 4 and the mounting seat 1. That is, by forming a fixed connection between the connecting rod 4 and the mounting seat 1, when the mounting plate 2 is welded, since the mounting plate 2 forms a rigid connection with the positioning plate 3 and the connecting rod 4, the welding position of the mounting plate 2 is more fixed, thereby further improving the quality of welding and ensuring the flatness of the two mounting plates 2 after welding.

[0048] Optionally, in some embodiments, the fixing mechanism includes a fixing bolt that is rotatably installed on the connecting rod 4. When the connecting rod 4 needs to be fixed, one end of the fixing bolt is screwed into the threaded hole on the mounting base 1 to lock and fix the connecting rod 4 and the mounting base 1.

[0049] In other embodiments, the fixing mechanism includes two splints and a rotating rod. The two splints can slide on the connecting plate. The rotating rod is provided with two sections of threads with opposite rotation directions, and the two splints respectively cooperate with the two sections of threads. That is to say, when it is necessary to fix the connecting rod 4, the two splints are clamped on the reinforcing ribs on the mounting seat 1. By rotating the rotating rod, the two splints can lock the reinforcing ribs, thereby locking and fixing the connecting rod 4 and the mounting seat 1.

[0050] That is to say, the focus of the present invention is: the two positioning plates 3 are trimmed after flatness detection to ensure that the two positioning plates 3 are on the same plane, and at the same time, they are kept in a fixed position under the action of the connecting rod 4. After the mounting plate 2 is connected to the positioning plate 3, the mounting plate 2 is welded. Since the two mounting plates 2 are in a rigidly fixed state under the action of the positioning plate 3 and the connecting rod 4, welding is performed in this state. After welding, the flatness of the anti-climber mounting surface is guaranteed, the welding deformation is effectively controlled, the adjustment amount is reduced, and the welding quality of the traction beam at the driver's cab end and the subsequent anti-climber installation quality are guaranteed.

[0051] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention.
