[0036] 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.

[0037] This utility model provides, for example Figure 1-6The bogie axle box swing arm rubber joint press-fit fixture shown includes: a base plate 1, with a bearing seat 2 mounted on one side of the upper surface of the base plate 1; an axle box bogie body 4, with one end of the axle box bogie body 4 supported on the bearing seat 2; a pin 5, which is assembled to the other end of the axle box bogie body 4; an installation device 3 for supporting the other end of the axle box bogie body 4 is mounted on the other side of the upper surface of the base plate 1; a positioning structure 6 for press-fitting the pin 5 is inserted through the top of the pin 5; a positioning plate 7 for positioning the pin 5 is inserted into the positioning structure 6; and the bearing seat 2 facilitates the positioning of the axle box bogie body 4. One end of the bogie body 4 is supported. The mounting device 3 facilitates stable support during the disassembly and assembly of the bogie body 4 and the pin 5. The positioning structure 6 is placed on the pin 5 to position the angle of the pin 5 and prevent the assembly angle between the pin 5 and the bogie body 4 from shifting. The two ends of the positioning plate 7 are respectively inserted between the bogie body 4 and the positioning structure 6, which facilitates the positioning of the relative angle between the bogie body 4 and the positioning structure 6, making the angle of the positioning structure 6 relative to the bogie body 4 more stable.

[0038] Specifically, the mounting device 3 includes: a mounting base 31, which is mounted on the upper surface of the base plate 1; a bearing assembly 32, which is mounted on the top of the mounting base 31 and is used for bearing and positioning the end of the axle box bogie body 4. The bearing assembly 32 includes: a bearing plate 321, which rests on the top of the mounting base 31 and has an outer diameter larger than the inner diameter of the mounting base 31; a positioning protrusion ring 323, which is integrally connected to the top of the bearing plate 321 and is inserted into the interior of the axle box bogie body 4, with an inner diameter smaller than the inner diameter of the mounting base 31; the bearing assembly 32 also includes: a mounting protrusion ring 322, which is integrally connected to the bottom of the bearing plate 321 and cooperates with the mounting base 31; and an insertion post 324, which is connected to the lower surface of the bearing plate 321 and is connected to the mounting base 31. 1. The interlocking connection, and the interlocking post 324 is used for positioning the mounting base 31 and the load-bearing component 32 during assembly. The mounting convex ring 322 facilitates the engagement with the inner cavity of the limiting groove 301, making the assembly of the load-bearing component 32 on the top of the mounting base 31 more stable. The positioning convex ring 323 facilitates the more stable assembly between the load-bearing plate 321 and the axle box bogie body 4, preventing positional deviation between the axle box bogie body 4 and the pin 5 during assembly. The positioning convex ring 323 can also limit the pin 5 during assembly, preventing over-assembly of the pin 5 relative to the axle box bogie body 4 when pressing the pin 5. The positioning convex ring 323 facilitates the determination of the lower limit of the pin 5's movement. The interlocking between the interlocking post 324 and the inner cavity of the mounting hole facilitates the positioning of the assembly between the mounting base 31 and the load-bearing component 32, preventing the load-bearing component 32 from rotating arbitrarily after assembly, making the assembly between the mounting base 31 and the load-bearing component 32 more stable.

[0039] Furthermore, a limiting groove 301 is provided at the top of the inner cavity of the mounting base 31. The limiting groove 301 cooperates with the mounting protrusion 322. Multiple mounting holes are provided at the top of the mounting base 31. The mounting holes cooperate with the through post 324. The limiting groove 301 also facilitates the limiting of the other end of the axle box bogie body 4. During the disassembly of the pin 5, the bearing component 32 is removed, so that the end of the axle box bogie body 4 directly cooperates with the inner cavity of the limiting groove 301. Since the inner diameter of the mounting base 31 is larger than the inner diameter of the other end of the axle box bogie body 4, when the positioning structure 6 is pressed, the positioning structure 6 presses down on the pin 5. Since the diameter of the positioning structure 6 is smaller than the inner diameter of the axle box bogie body 4, the positioning structure 6 can be pressed into the interior of the axle box bogie body 4, and then the pin 5 falls into the interior of the mounting device 3 for collection, thereby realizing the disassembly of the relative position between the pin 5 and the axle box bogie body 4.

[0040] Specifically, the positioning structure 6 includes: a positioning sleeve 61, which is inserted into the top of the pin 5; a positioning groove 62, which is formed on the side of the outer wall of the positioning sleeve 61, and the positioning plate 7 cooperates with the positioning groove 62; and a through slot 63, which is formed through the middle of the positioning sleeve 61 and is inserted into the pin 5. The positioning sleeve 61 facilitates the downward pressing of the pin 5, and the diameter of the positioning sleeve 61 is smaller than the inner diameter of the other end of the axle box bogie body 4, so that when the positioning sleeve 61 presses down on the pin 5, it can be fitted into the interior of the axle box bogie body 4 in a clearance fit, so as to facilitate the downward pressing of the pin 5. The disassembly of the positioning structure 6 after entry is achieved by using a harpoon-shaped end of the positioning plate 7. One end is inserted into the axle box bogie body 4 for positioning, and the other end is inserted into both sides of the positioning sleeve 61. This allows the positioning plate 7 to fit against the inner wall of the positioning groove 62. Through the cooperation between the positioning plate 7 and the positioning groove 62, the relative angle between the positioning sleeve 61 and the axle box bogie body 4 is limited. Combined with the insertion positioning between the through slot 63 and the pin 5, the assembly angle between the pin 5 and the axle box bogie body 4 can be positioned during the assembly of the pin 5, preventing the pin 5 from shifting at the assembly angle.

[0041] Furthermore, both the bearing seat 2 and the mounting device 3 are equipped with a buffer mechanism 8. The buffer mechanism 8 includes: a threaded rod 81, which is fixedly installed on the base plate 1; a threaded cylinder 82, which is threadedly sleeved on the outside of the threaded rod 81; and a buffer pad 83, which is fixedly installed on the outside of the threaded cylinder 82. The buffer pad 83 is made of nylon. The buffer pad 83 is used to buffer and support the pin 5 when it is disassembled and falls, preventing damage to the pin 5 when it falls. The threaded engagement between the threaded cylinder 82 and the threaded rod 81 facilitates the installation of the buffer pad 83.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
