[0001] The utility model relates to the technical field of bullet train maintenance, in particular to a manufacturing device for an axial end diversion tooling for flaw detection operation of bullet trains. Background Technique
[0002] When flaw detection operation is carried out on the axle of a bullet train, a diversion tooling is needed for assistance to prevent the coupling liquid in the hollow axle from flowing into the axle box. The existing diversion toolings used for CRH380A, CRH2A, CRH380D, and CR300AF type bullet trains in our section cannot meet the flaw detection requirements of CRH3A-A type bullet trains. The axial end matching length of the diversion tooling is insufficient and cannot contact and seal with the hollow axle hole. During the flaw detection process, the coupling liquid will flow into the axle box, and during the operation of the bullet train, the coupling liquid may seep to the outside of the axle box and is easily stopped by TEDS.
[0003] The serious mismatch of the existing diversion tooling seriously affects the flaw detection work of CRH3A-A type bullet trains. During the flaw detection operation, it is necessary to frequently clean the coupling liquid in the axle box. If the cleaning is not in place, there is a risk of the train set being stopped, interfering with the transportation order. Therefore, it is necessary to process the axial end diversion tooling used for the flaw detection work of CRH3A-A type bullet trains. Currently, it can be processed by outsourcing, but the processing time is long, the cost is high, and there are many inconveniences. When using a 3D printing device for processing, rapid processing can be achieved and the waiting time can be reduced. However, in the prior art when printing metal parts, during the printing of workpieces, the cooling effect is poor, the dimensional accuracy of the parts cannot be ensured, the residual stress cannot be reduced, and even deformation may occur, affecting the use effect.

[0023] Embodiment:
[0024] Refer to Figures 1-4 , a manufacturing device for an axle-end diversion tooling for flaw detection operation of multiple unit trains, including a printer main body 1. A nozzle 101 is arranged on the printer main body 1 through a transmission part. The transmission part includes an electric slide table arranged on the printer main body 1. A mounting seat is fixedly arranged at the output end of the electric slide table. A guide rod is fixedly arranged on the mounting seat, and a first lead screw is rotatably arranged to drive a connecting seat to drive the nozzle 101 to move up and down. Moreover, a second lead screw is used to drive the nozzle 101 to slide along the connecting seat, realizing the movement of the nozzle 101 in the x and z directions, improving the use effect. It further includes: a bearing table 3. An installation groove 102 is formed on the printer main body 1. The bearing table 3 is fixedly arranged at the top of the installation groove 102. A mesh plate 301 is fixedly arranged on the bearing table 3. A bottom plate in a circular ring structure is placed on the top of the mesh plate 301. During printing, printing starts from the top end face of the bottom plate, which is convenient for removing the printed diversion tooling from the mesh plate 301. A heat dissipation fan 2 is fixedly arranged at the inner bottom of the installation groove 102, and an air outlet 104 communicating with the installation groove 102 is formed at the bottom of the printer main body 1. A protective net is fixedly arranged in the air outlet 104. During use, by fixedly arranging the heat dissipation fan 2 in the installation groove 102, during the printing process, when the heat dissipation fan 2 is started, air can be sucked through the mesh plate 301 and then discharged from the air outlet 104. At this time, the air flows from top to bottom. On the one hand, it can improve the heat dissipation effect and reduce the deformation of the workpiece. On the other hand, the air after heat exchange above flows away from below the workpiece, which can appropriately heat the workpiece below, making the temperature of the workpiece gradually decrease from top to bottom, avoiding large temperature differences inside the workpiece, which may cause cracks or deformation; a wind shield cylinder 4 is arranged on the printer main body 1 in a lifting manner. A lifting part for driving the wind shield cylinder 4 to lift is arranged in the printer main body 1. During use, by arranging the wind shield cylinder 4 on the printer main body 1 in a lifting manner, as the height of the workpiece increases, the wind shield cylinder 4 slowly rises, enabling the air to flow downward from above the workpiece as much as possible, reducing the situation where air directly enters the installation groove 102 from the mesh plate 301 at the bottom of the workpiece, resulting in a reduction in the heat dissipation effect.
[0025] Refer to Figure 3 and Figure 4, the lifting part can use a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder to drive the windshield cylinder 4 to lift. Here, we design the lifting part as follows: a guide ring 402 is fixedly arranged at the bottom of the windshield cylinder 4, a chute 103 is opened in the printer main body 1, the guide ring 402 is slidably arranged in the chute 103, a first plane is fixedly arranged on the outer wall of the guide ring 402, and a second plane corresponding to the plane is fixedly arranged in the chute 103. The first plane and the second plane are abutted against each other. During the sliding process, it can ensure the reliable sliding of the guide ring 402 and avoid rotation or deflection, which affects the normal use. A screw rod 5 is rotatably arranged in the chute 103, the guide ring 402 is threadedly connected with the screw rod 5, and a motor 501 for driving the screw rod 5 to rotate is fixedly arranged in the printer main body 1. When in use, by starting the motor 501 to drive the screw rod 5 to rotate, the windshield cylinder 4 can be driven to slide up and down through the guide ring 402, so as to block the air and improve the use effect.
[0026] Refer to Figures 1-3 , a plurality of groups of through holes 401 are opened in the windshield cylinder 4. The number of the through holes 401 is two groups to one hundred groups, preferably fifty groups. Moreover, the axes of the through holes 401 are all inclined. Preferably, the axes are inclined downward from the inner wall to the outer wall of the windshield cylinder 4. When in use, by opening the through holes 401 in the windshield cylinder 4, it is convenient for air to enter the windshield cylinder 4 and improve the use effect.
[0027] Refer to Figure 3 and Figure 4 , a disturbing plate 6 is arranged in the installation groove 102. Rotating shafts 601 are fixedly arranged at both ends of the disturbing plate 6, and the two rotating shafts 601 are rotatably connected to the inner wall of the installation groove 102. And a driving part for driving the disturbing plate 6 to swing is arranged in the installation groove 102. When in use, by driving the disturbing plate 6 to swing through the driving part, on the one hand, it can prevent air from always entering the installation groove 102 from one direction of the workpiece, which affects the cooling effect. On the other hand, by arranging the disturbing plate 6, the air can enter the installation groove 102 alternately from both sides of the workpiece, improving the use effect.
[0028] Refer to Figure 3 and Figure 4 , the driving part can use a motor or a pneumatic cylinder to drive the disturbing plate 6 to swing. Here, we design the driving part as follows: a rotating shaft 701 is rotatably arranged in the printer main body 1, an eccentric rod 702 is fixedly arranged at one end of the rotating shaft 701 extending into the installation groove 102, a connecting rod 703 is rotatably arranged on the eccentric rod 702, and one end of the connecting rod 703 far from the eccentric rod 702 is rotatably connected to the disturbing plate 6. When in use, by driving the rotating shaft 701 to drive the eccentric rod 702 to rotate, the disturbing plate 6 can be driven to reciprocally swing around the axis of the rotating shaft 601 through the connecting rod 703, improving the use effect, which is similar to a crank-rocker mechanism.
[0029] Refer to Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 , a limiting groove is formed in the inner wall of the windshield cylinder 4, and a rack 403 is fixedly arranged on the inner wall of the limiting groove. A gear 7 is fixedly arranged at one end of the rotating shaft 701 extending into the limiting groove. The gear 7 is meshed with the rack 403. During use, when the windshield cylinder 4 slides up and down, the gear 7 can be driven to rotate through the rack 403, so that the rotating shaft 701 and the eccentric rod 702 can be driven to rotate, and the disturbance plate 6 can be driven to swing through the connecting rod 703. The structure is simple and the driving effect is reliable.
