The steel back bearing is assembled by hydraulic equipment, with a working pressure of 5T, infinitely adjustable pressure, and equipped with a hydraulic pump station.

The pneumatic clamping mechanism levels the irregular cylinder bottom to ensure that the central axis of the bearing hole at the bottom of the oil cylinder is vertically upward. The pneumatic slide controls the in and out of the leveling mechanism to avoid collision between the cylinder to be assembled and the leveling mechanism during transportation.

As shown in Figure 7, the servo lifting mechanism 10 includes a lifting platform 101, a fixed plate 102, a guide column 103, a screw hoist 104, a guide sleeve 108 and a driving mechanism.

The hydraulic buffer 82 is arranged on both sides of the tooling mounting plate and is connected to the upper pneumatic slide mounting plate. The bottom of the upper pneumatic slide mounting plate is slidably connected to the lower pneumatic slide through a slider.

As shown in Figure 9, the lower pneumatic slide 9 includes a lower pneumatic slide mounting plate 91, a second cylinder 92, a second floating joint 93, a third linear guide 94 and a second hydraulic buffer 95.

The steel back bearing is transferred to the top of the bearing hole by the pushing cylinder of the pushing mechanism 4 and then returned to wait for press installation;

(6) The press machine works, pressing down at high speed until the steel back bearing enters the mounting hole at the bottom of the cylinder, and then turning from high speed to low speed to press the steel back bearing into place. At the same time, the pin shaft returns to the initial position, the locking cylinder locks the pin shaft, and the pressure head quickly withdraws to the initial position to complete the press fitting;

(7) The rotating pressing cylinder presses the cylinder body, the upper pneumatic slide pulls the cylinder back to its original position, and the lower pneumatic slide moves the cylinder to station one;

(8) The robot lowers the material from the cylinder to the unloading trolley, and the cycle repeats.
