[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention uses the magnetic attraction of two electromagnetic plates to make the first rectangular frame move toward the second rectangular frame until it fits the bottom end of the second rectangular frame.

By adjusting the height of the bearing plate, it is convenient for the staff to install the bushing. When loading the bushing, there is no need to contact the damping liquid in the damping liquid pool. After the bushing is loaded, the power supply of the two electromagnetic plates is disconnected to immerse the bushing on the bearing plate in the damping liquid. By driving the hydraulic cylinder 21, the pressure head 22 is slowly pressed into the bushing to allow air time to escape. After the bushing is assembled, when it is necessary to unload the bushing, the bearing plate is raised. The rise of the bearing plate not only facilitates the drainage of the bushing, but also prevents the staff from contacting the damping liquid in the damping liquid pool, so that the equipment can reduce the pollution of the damping liquid, thereby facilitating the press-fitting quality of the equipment and the service life of the bushing, making the equipment more convenient to use.

[0017] 2. In the process of draining the bushing, the next bushing can be installed. After the next bushing is installed, the drained bushing is removed, and then the hydraulic telescopic rod is driven to make the sliding plate slide horizontally. The horizontal sliding of the sliding plate can move the installed bushing to the bottom of the pressure head, and the hydraulic cylinder is driven again to slowly press the pressure head into the bushing. The progressive loading of the bushing facilitates the continuous sliding assembly of the bushing, thereby accelerating the overall working progress of the equipment and making the equipment easier to use.

[0040] When the present invention is used, the damping liquid is selectively filtered according to the quality of the damping liquid in the damping liquid pool 1 and the actual use needs of the staff. When the damping liquid needs to be filtered, the damping liquid in the damping liquid pool 1 is input into the filter 13 for filtering by driving the first water pump. By setting a liquid level height sensor 15 in the damping liquid pool 1, it is convenient to measure the filtered damping liquid. After the damping liquid is filtered, it is convenient to input the filtered damping liquid into the damping liquid pool 1 through the water supply pipe 14 by driving the second water pump. The liquid level height sensor 15 facilitates the device to input a quantitative amount of damping liquid, thereby facilitating the device After the bushing to be assembled is covered and a certain amount of damping fluid is input, the temperature of the damping fluid in the damping fluid pool 1 is conveniently monitored in real time through the temperature sensor 17 arranged in its inner cavity. When the damping fluid is lower than the standard value, since the temperature sensor 17 is electrically connected to the annular electric heating tube group 12, the power supply of the annular electric heating tube group 12 will be automatically connected, and the damping fluid will be conveniently heated by the annular electric heating tube group 12. After it is heated to the rated temperature, the power supply of the annular electric heating tube group 12 will be cut off. By keeping the damping fluid in a constant temperature state, the subsequent bushing assembly quality of the equipment can be guaranteed;

[0041] After the damping liquid in the damping liquid pool 1 is adjusted, the power supply of the two electromagnetic plates 24 corresponding to the first rectangular frame 46 and the second rectangular frame 23 under the pressure head 22 is manually turned on, and the first rectangular frame 46 moves toward the second rectangular frame 23 through the magnetic attraction of the two electromagnetic plates 24 until it fits on the bottom of the second rectangular frame 23. The movement of the first rectangular frame 46 causes the bearing plate 42 to move synchronously, thereby facilitating the stretching of the spring group 41 to move the bearing plate 42 away from the damping liquid in the damping liquid pool 1, and then drive The servo motor 35 rotates the rotating rod 3, and the rotation of the rotating rod 3 causes the screw sleeves 32 on the two sections of the external thread 31 with opposite screw threads to move relative to each other. The relative movement of the screw sleeves 32 causes the connecting plate 33 to drive the clamping block 34 to enter the clamping groove provided on one side of the sliding rod 45, thereby facilitating the limiting of the carrying plate 42. The clamping block 34 is connected to the inner cavity of the connecting plate 33 through horizontal elastic sliding. When the carrying plate 42 is not under the pressure head 22, the clamping block 34 will retract into the inner cavity of the connecting plate 33, thereby facilitating the subsequent use of the device.

[0042] After the bearing plate 42 is limited, the bushing is gently placed into the assembly hole 51 of the bearing plate 42 to ensure that it is roughly aligned, and then the bushing is gently rotated or adjusted by hand to make it on the same axis as the center line of the assembly hole 51. After the bushing is installed, the corresponding bearing plate 42 is first released by driving the servo motor 35, and then the power supply of the two corresponding electromagnetic plates 24 is disconnected so that the bushing on the bearing plate 42 can be immersed in the damping liquid in the damping liquid pool 1, and then the air pump 47 is driven to blow water on the bushing through the blowing nozzle group 48. By blowing water on the bushing, it can be ensured that the press-fitting part is clean and dry, and residual moisture or other impurities can be prevented from affecting the press-fitting quality and the combination effect of the bushing and related components. Finally, the hydraulic cylinder 21 is driven to make the pressure head 22 is slowly pressed into the bushing to allow time for the air to escape. After the bushing is assembled, the power of the two corresponding electromagnetic plates 24 is turned on again to keep the bearing plate 42 away from the damping liquid in the damping liquid pool 1, so as to facilitate its draining. During the draining process, the next bushing can be installed. After the next bushing is installed, the drained bushing is removed, and then the hydraulic telescopic rod 16 is driven to make the sliding plate 4 slide horizontally. The horizontal sliding of the sliding plate 4 can move the installed bushing to the bottom of the pressure head 22, and the hydraulic cylinder 21 is driven again to make the pressure head 22 slowly pressed into the bushing. The progressive loading of the bushing facilitates the continuous sliding assembly of the bushing, thereby facilitating the acceleration of the overall working progress of the equipment and making the equipment easier to use.
