[0055] In one embodiment, Figure 2-Figure 4 As shown, the press-fitting mechanism 2 includes a hydraulic cylinder 18 and a piston rod 16 connected to the hydraulic cylinder 18. The hydraulic cylinder 18 is fixed on the fuselage 1. The pressure head 24 is connected to the head of the piston rod 16.

Through the arrangement of the pressure cover 13 and the connecting plate 27, it is convenient to fix the connector 14 and the scale connecting shaft 26 on the movable slide 11. It should be noted that the specific structure and assembly relationship of each component can be as follows. Figure 5 , Figure 6 , Figure 8-Figure 18 As shown, no further elaboration is given here.

[0058] In one embodiment, Figure 3 As shown, a linear bearing 12 is also provided on the cylindrical guide rail 10, and the movable slide plate 11 is mounted on the linear bearing 12. Thus, the movement of the movable slide plate 11 can be made smoother, and the precision of press fitting can be improved.

[0059] In one embodiment, Figure 3 As shown, the press-fitting mechanism 2 further includes a top plate 17 and a bottom plate 19, the top plate 17 is fixed to the upper part of the fuselage 1, the bottom plate 19 is fixed to the workbench 101, the positioning seat 21 and the bracket 8 are both fixed to the bottom plate 19, the lower end of the cylindrical guide rail 10 is fixed to the bottom plate 19, the upper end of the cylindrical guide rail 10 is fixed to the top plate 17, and the hydraulic cylinder 18 is fixed to the top plate 17. This can enhance the stability of the entire device and facilitate the installation of various components, and the press-fitting mechanism 2 is fixed to the fuselage 1.

[0060] Optionally, the piston rod 16 is fixedly connected to the connector 14 via a locking nut 15, the connecting plate 27 and the gland are fixed to the movable slide 11 via screws, the connector 14 is pressed against the gland 13, and the connector 14 is connected to the movable slide 11 via the gland 13, the scale connecting shaft 26 is connected to the connecting plate 27 via screws, the pressure head 24 is inserted into the scale connecting shaft 26, and the fastening connection between the pressure head 24 and the scale connecting shaft 26 is achieved by tightening the fixing handle 25. The bottom plate 19 is connected to the workbench 101 of the fuselage 11 via screws, and the positioning seat 21 is connected to the bottom plate 19 via the knob plunger 20. During press-fitting, the rubber joint 23 is installed on the pressure head 24, and the head of the rubber joint 23 is embedded in the positioning groove 241 of the pressure head 24.

[0061] In one embodiment, Figure 7 As shown, the bracket 8 includes a slide rail 81 and a bracket, a part of the slide rail 81 is fixed on the bottom plate 19, and the other part extends out of the bottom plate 19, and the bracket includes a sliding seat 82, a first support portion 83 and a second support portion 84, and the sliding seat 82 can be installed on the slide rail 81 movably along the slide rail 81, the first support portion 83 and the second support portion 84 are symmetrically installed on the top of the sliding seat 82, and a bracket for supporting the shock absorber 9 is formed between the first support portion 83 and the second support portion 84. Therefore, when the suspension ring 22 of the shock absorber 9 is positioned on the positioning seat 21, the shock absorber 9 can be placed in the drag groove to achieve support, and then the shock absorber 9 will not move when the rubber joint 23 is pressed, so as to achieve press-fitting accuracy and efficiency.

[0062] In one embodiment, a sidewall of the positioning seat 21 is provided with an avoidance groove 212, and when the lifting ring 22 of the shock absorber 9 is positioned on the positioning seat 21, the avoidance groove 212 is used to avoid the shock absorber 9. Therefore, when the lifting ring 22 of the shock absorber 9 is positioned on the positioning seat 21, one end of the shock absorber 9 on which the rubber joint 23 is installed can be placed horizontally, and the positioning seat 21 will not interfere with the shock absorber 9, thereby making the shock absorber 9 in a horizontal state during press-fitting, thereby improving press-fitting efficiency and precision.

[0063] In a specific example, the press-fitting process of a rubber joint 23 may be as follows:

[0064] Turn on the power switch 3, start the machine, observe the reading of the pressure gauge 7 to understand the current system pressure value of the machine, and check whether the process requirements of the pressure value of the rubber joint 23 of the different types of shock absorbers 9 can be met. If not, turn the knob of the pressure regulating valve 6 to adjust the system pressure to the required pressure range. Place the shock absorber 9 on the bracket 8, and the lifting ring 22 in the positioning hole 211 of the positioning seat 21, so that the lower end face of the lifting ring 22 is close to the step surface of the positioning hole 211 of the positioning seat 21. The rubber joint 23 is placed in the mounting hole of the pressure head 24. Start the touch screen controller 4, click the current automatic key, and the machine tool piston rod 16 moves down quickly according to the set program, and starts to move down slowly when the rubber joint 23 is 5mm away from the upper end face of the lifting ring 22. After moving down to the set position, the piston rod 16 rises quickly to complete a press. When there is a requirement for the installation angle between the rubber joint 23 and the hanging ring 22, it is only necessary to rotate the scale connecting shaft 26 by a certain degree as required, and the angle requirement between the rubber joint 23 and the hanging ring 22 can be ensured during press-fitting.

[0065] Furthermore, the special equipment of this embodiment realizes automation of the machine tool operation process, and the rubber joint pressing force can be adjusted and controlled according to the force requirements of different shock absorber types; the rubber joint pressing depth can be adjusted and controlled according to different shock absorber types through displacement sensors, and the size is stable, which can fully meet the symmetry requirements of the rubber joint mounting hole to the hanging ring; for shock absorbers with installation angle requirements between the rubber joint and the hanging ring, this can be achieved by rotating the scale connecting shaft. A technical problem in the manufacturing and assembly process of high-speed train shock absorbers has been solved.

[0066] Therefore, the special equipment for pressing the rubber joints of shock absorbers for high-speed trains of the utility model solves the technical problems in the prior related technologies such as excessive pressing force during the pressing of the rubber joints of shock absorbers, resulting in damage to the rubber joints; excessive symmetry of the rubber joint mounting holes to the lifting rings; large errors in the mounting angles due to visual inspection; low production efficiency, which seriously affects production capacity; poor pressing accuracy and high labor intensity.
