Two positioning blocks 5 are arranged on the sealing bottom plate 3 to position the two bearing holes of the left box cover. A first sealing ring 6 corresponding to the edge of the left box cover is arranged on the sealing bottom plate 3 to completely seal the edge of the left box cover. At the same time, a second sealing ring 7 is arranged on the top surface of the positioning block 5 to seal the oil passage. A third sealing ring 8 corresponding to the through holes on the left box cover is arranged on the sealing bottom plate 3 to keep the cavity in a closed state. The top surface of the sealing bottom plate 3 has a sunken inflation cavity 9, and an inflation passage 10 communicating with the inflation cavity 9 is arranged on the sealing bottom plate 3. Air is inflated into the inflation cavity through the airtightness detection device and kept under pressure for a period of time to determine whether there is air leakage. To make the left box cover fit tightly with the sealing ring and prevent movement. A vertically lifting pressing plate 11 is arranged directly above the sealing bottom plate 3, and a plurality of elastic pressing rods 12 are distributed on the bottom surface of the pressing plate 11; the plurality of elastic pressing rods press the left box cover from the top surface. To ensure the stable movement of the lifting pressing plate, a guiding rod is arranged between the pressing plate 12 and the sealing mounting plate 2. To prevent the pressing plate 12 from pressing down excessively, limit ejector rods are arranged at the four corners of the pressing plate 12 in this embodiment.

[0021] The press-fitting assembly includes a press-fitting mounting plate 20 disposed on the mounting table board. A press-fitting backing plate 21 is arranged on the press-fitting mounting plate 20.

The front end of the press-fitting rod 24 is in sliding fit with the press-fitting channel. When the press-fitting rod 24 moves forward, the steel ball entering the press-fitting channel can be press-fitted onto the left box cover. To enable the press-fitting action to be repeated, a steel ball filling mechanism is arranged above the press-fitting slide block 22 in this embodiment.

[0022] To facilitate the positioning of the left box cover assembly, an auxiliary positioning block 13 is arranged on the sealing bottom plate 3 in this embodiment. The edge of the auxiliary positioning block 13 in contact with the left box cover assembly is a profiling structure. To enable the left box cover assembly to be balanced in force during steel ball press-fitting and avoid displacement, the auxiliary positioning block 13 is arranged at the edge on the opposite side of the press-fitting hole of the left box cover assembly, so as to provide a reverse support force for press-fitting.

[0023] As Figure 2 shown, a top plate 14 is arranged on the mounting table board through columns. A pressing plate lifting cylinder 15 for driving the pressing plate 11 is arranged on the top plate 14. A guiding device is arranged between the pressing plate 11 and the top plate 14. The guiding device includes guiding rods arranged at the four corners of the top surface of the pressing plate 11, and linear bearings slidably matched with the guiding rods are arranged on the top plate 14. A boosting cylinder 16 pressing against the top surface of the pressing plate 11 is also arranged on the top plate 14. When pressing the left box cover, first lower the pressing plate 11 so that the spring pressing rod 12 fits against the top surface of the left box cover, and then the front end of the piston rod of the boosting cylinder 10 tightly presses against the top surface of the pressing plate 11.

[0024] Further, the elastic pressing rod 12 includes a spring seat 120, a spring 121, a connecting rod 122, a pressing rod 123, and a pressing head 124 connected in sequence from top to bottom.

The two ends of the return spring are limited between the press-fitting slide block 22 and the press rod slide block 27. When the piston rod of the press-fitting electric cylinder 26 extends, due to the action of the return spring, the press rod slide block 27 and the press-fitting slide block 22 move forward together. When the ball guide seat 23 on the press-fitting slide block 22 abuts against the left box cover, the press-fitting slide block 22 stops, and the press rod slide block 27 continues to approach the press-fitting slide block 22. Thus, the press rod 24 presses the steel ball in the press-fitting slide block 22 into the press-fitting hole of the left box cover assembly.

[0026] When the piston rod of the press-fitting electric cylinder 26 retracts and the press rod 24 retracts, in order to prevent the ejector rod 28 from detaching from the press rod slide block 27, a limit pin 29 is provided at one end of the ejector rod 28.

The second guide pipe 36 is aligned with the steel ball dropping hole. The lower end of the second guide pipe 36 extends above the press-fitting slide block 22. The steel balls in the steel ball storage box 31 automatically enter the first guide pipe 32. When the steel ball receiving groove on the feeding slider 34 moves backward and is aligned with the first guide pipe 32, just one steel ball falls into the steel ball receiving hole. When the steel ball receiving hole on the feeding slider 34 moves forward and is aligned with the steel ball dropping hole on the feeding chute 33, the steel ball enters the second guide pipe 36. Furthermore, when the press-fitting slide block 22 moves below the second guide pipe 36, the steel ball enters the steel ball press-fitting channel.

[0028] The feeding chute 33 and the feeding cylinder 35 are arranged on the steel ball filling bracket 30 through a mounting seat plate 37. A limit slider 38 is provided at the front end of the piston rod of the feeding cylinder 35.
