Description

Technical Field

[0001] This utility model belongs to the field of freight car sleeper beam processing technology, specifically relating to a railway freight car sleeper beam welding and turning device. Background Technology

[0002] In the production of a certain type of railway freight car sleeper beam assembly, to ensure the welding quality of the welds between the various plate components, it is necessary to flip the welds to a flat position before performing fillet welds. Currently, the plate components are welded on a standard material rack platform. When flipping for welding is required, manual or overhead crane assistance is used to flip the sleeper beam assembly 90 degrees to the left and right, and then level it under the sleeper beam using wooden blocks before welding. The drawback is that, due to the structural limitations of the sleeper beam assembly, even with wooden blocks for adjustment after flipping, it is impossible to completely guarantee the straightness of the welds. Manual flipping not only increases the labor intensity of the operators but also poses significant safety hazards.

[0003] Patent application number 202023059763.3 discloses a railway freight car sleeper beam welding and tilting device. The support frame has pin holes, and a driven rotating head and a driving rotating head are respectively located at both ends of the support frame. A driven positioning seat and a driving positioning seat are respectively located at one end of the driven and driving rotating heads. The driven positioning seat has a positioning mechanism A, and the driving positioning seat has a clamping mechanism and a positioning mechanism B. A handle is located at the other end of the driving rotating head, and a locking device is fixedly sleeved on the driving rotating head to restrict the tilting of the railway freight car sleeper beam welding and tilting device.

[0004] The aforementioned railway freight car sleeper beam welding and turning device uses a clamping and locking mechanism to clamp and fix both ends of the sleeper beam. During the drilling and rotation process, the active rotating head drives the two ends of the sleeper beam to be welded and the driven rotating head to rotate. When the sleeper beam rotates after welding one surface, the sleeper beam body has to bear the torque generated during rotation, which causes the weld point to be prone to deformation when bearing torque, resulting in poor welding effect of the sleeper beam. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a railway freight car sleeper beam welding and turning device. This railway freight car sleeper beam welding and turning device aims to solve the technical problem that the rotating sleeper beam body has to bear the torque generated during rotation, which leads to the welding point being prone to deformation when bearing the torque, resulting in poor welding effect of the sleeper beam.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a railway freight car sleeper beam welding and turning device, including a support frame, turning components arranged on both sides of the inner wall of the support frame, and a connecting rod fixed between two turning components. The sleeper beam body is arranged between the two turning components. The turning component includes a rotating plate installed on the inner wall of the support frame and a sliding rod welded and fixed to both ends of the connecting plate. Clamping frames for fixing the sleeper beam body are slidably installed on multiple sliding rods.

[0009] When using this technical solution, a connecting rod is installed between the two flipping components, and the internal hex bolts are threaded into the slide rods to keep the sleeve and connecting plate fixed to the connecting shaft stable. The two rotating plates rotate synchronously through the connecting rods during rotation, which greatly reduces the torque borne by the bolster body and reduces the deformation of the bolster body during rotation. By sliding components are slidably sleeved on multiple slide rods, after the clamping frame is in contact with the outer wall of the bolster body, the sliding components slide on the surface of the bolster body to clamp the bolster body at different positions. After welding, the clamping frame can slide to separate from the bolster body. After the clamping frame moves, the nuts are tightened on the bolts to keep the clamping frame fixed to the bolster body, thus improving the convenience of welding, fixing and disassembling the bolster body.

[0010] Preferably, a rotating shaft is welded and fixed to the side wall of the rotating plate, and a bearing sleeved on the rotating shaft is embedded in the support frame.

[0011] Furthermore, a servo motor is fixedly installed on the side wall of the support frame, and the shaft of the servo motor is fixedly connected to the rotating shaft.

[0012] Furthermore, connecting plates are welded and fixed to both ends of the connecting rod, and sleeves that are fitted onto the sliding rod are welded onto the connecting plates.

[0013] Furthermore, an internal hexagon bolt is embedded in the side wall of the sleeve, and the internal hexagon bolt is threaded into the slide rod.

[0014] Furthermore, a sliding member is welded and fixed to the outer wall of the clamping frame, the sliding member is slidably sleeved on the slide rod, and a baffle is threaded onto the end of the slide rod.

[0015] Furthermore, bolts are symmetrically installed between the two clamping frames on the same side, and a nut is threaded onto one end of each bolt passing through the clamping frame.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model uses a connecting rod installed between two flipping components, with an internal hex bolt threaded into the slide rod to keep the sleeve and connecting plate fixed to the connecting shaft stable. The two rotating plates rotate synchronously through the connecting rod during rotation, which greatly reduces the torque borne by the bolster body and reduces the deformation of the bolster body during rotation.

[0019] By sliding the sliding components onto multiple sliding rods, the clamping frame is fitted against the outer wall of the bolster beam body. The sliding components slide on the surface of the bolster beam body, thereby clamping the bolster beam body at different positions. After welding, the clamping frame can slide to separate from the bolster beam body. After the clamping frame moves, the nuts are tightened on the bolts, thus keeping the clamping frame fixed to the bolster beam body, improving the convenience of welding, fixing, and disassembling the bolster beam body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a railway freight car sleeper beam welding and turning device, the structural schematic diagram of which is shown below. Figures 1 to 4 As shown, it includes a support frame 1, a flipping assembly disposed on both sides of the inner wall of the support frame 1, and a connecting rod 2 fixed between the two flipping assemblies. A pillow beam body 4 is disposed between the two flipping assemblies. The flipping assembly includes a rotating plate 3 installed on the inner wall of the support frame 1 and a sliding rod 5 welded and fixed to both ends of the connecting plate 9. Clamping frames 14 for fixing the pillow beam body 4 are slidably installed on multiple sliding rods 5.

[0028] A rotating shaft 8 is welded and fixed to the side wall of the rotating plate 3. A bearing 7 is embedded in the support frame 1 and sleeved on the rotating shaft 8. A servo motor 6 is fixedly installed on the side wall of the support frame 1. The shaft of the servo motor 6 is fixedly connected to the rotating shaft 8. Preferably, it is an MR-J2S type servo motor 6, which can maintain axial positioning after the machine stops.

[0029] Both ends of the shaft are welded and fixed with connecting plates 9. A sleeve 10 is welded onto the connecting plate 9 and fitted onto the slide rod 5. An internal hex bolt 11 is embedded in the side wall of the sleeve 10 and threaded into the slide rod 5. The connecting shaft 2 protrudes from one side of the bolster body 4 and will not affect the welding of the bolster body 4. The bolster body 4 is set at the center position for welding. The internal hex bolt 11 is threaded into the slide rod 5 to keep the sleeve 10 and connecting plate 9 fixed to the connecting shaft stable. The two rotating plates 3 rotate synchronously through the connecting shaft 2 during rotation, which greatly reduces the torque borne by the bolster body 4 and reduces the deformation of the bolster body 4 during rotation.

[0030] A sliding member 13 is welded and fixed to the outer wall of the clamping frame 14. The sliding member 13 is slidably sleeved on the slide rod 5. A baffle 12 is threaded onto the end of the slide rod 5. Bolts are symmetrically installed between the two clamping frames 14 on the same side. A nut 16 is threaded onto one end of the bolt passing through the clamping frame 14. After the clamping frame 14 is in contact with the outer wall of the bolster beam body 4, it slides on the surface of the bolster beam body 4 through the sliding member 13, thereby clamping the bolster beam body 4 at different positions. After welding, the clamping frame 14 can slide to separate from the bolster beam body 4. After the clamping frame 14 moves, the nut 16 is tightened on the bolt, thereby keeping the clamping frame 14 and the bolster beam body 4 fixed.

[0031] Working principle: When using the device of this technical solution, the two parts of the bolster beam body 4 that need to be welded are inserted into the two sets of clamping frames 14. The nuts 16 are tightened on the bolts, so that the clamping frames 14 and the bolster beam body 4 are fixed. After fixing, the clamping frames 14 are pulled to move on the sliding rod 5 through the sliding member 13, so that the two parts of the bolster beam body 4 fit together. The two parts of the bolster beam body 4 are fixed by spot welding first, and then the weld seam of the two parts of the bolster beam body 4 is welded. After welding one side, the servo motor 6 is started to drive the rotating shaft 8 to rotate 90 degrees. The rotating plates 3 on the two rotating shafts 8 rotate synchronously through the connecting rod 2 during the rotation, which greatly reduces the torque borne by the bolster beam body 4 and reduces the deformation of the bolster beam body 4 during the rotation. After the bolster beam body 4 is completely welded, the nuts 16 are loosened, so that the clamping frames 14 slide towards the end of the bolster beam body 4 and separate from it, which improves the convenience of welding, fixing and disassembling the bolster beam body 4.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
