It can be understood that the air cylinder 372 pushes or pulls the oil-sealed press ring mounting assembly 38, and then pushes or pulls the oil-sealed press ring 33 to slide in the accommodating hole 35, so that the oil-sealed press ring mounting assembly 38 has a first position where the oil-sealed press ring 33 presses the framework oil seal 300 into the cross bearing 200 and a second position where the oil-sealed press ring 33 is reset. For example, when the oil-sealed compression ring mounting assembly 38 is in the first position, the oil-sealed compression ring mounting assembly 38 abuts against the outer ring mounting assembly 36, and the oil-sealed compression ring 33 pushes the framework oil seal 300 to press into the cross bearing 200; when oil blanket clamping ring installation component 38 was in the second position, oil blanket clamping ring installation component 38 butt in mounting panel 5 to make oil blanket clamping ring installation component 38 be located initial position, prevent that oil blanket clamping ring installation component 38 from excessively resetting.

Preferably, when the oil seal compression ring mounting assembly 38 slides under the driving of the driving mechanism 37, the oil seal connecting plate 381 selectively abuts against the mounting plate 5 or the first connecting plate 361. For example, when the oil seal connecting plate 381 abuts against the first connecting plate 361, that is, the oil seal compression ring mounting assembly 38 is located at the first position, that is, the frame oil seal 300 is pressed into the cross bearing 200; when the oil seal connecting plate 381 abuts against the mounting plate 5, the oil seal pressing ring mounting assembly 38 is in the second position. Preferably, the side of the side plate 382 close to the first connecting plate 361 is provided with a avoiding hole 3821, and with the help of the avoiding hole 3821, the second connecting plate 362 can be placed in the avoiding hole 3821 and connected with the mounting plate 5, so that the clamp mechanism 3 has reasonable space utilization, a compact structure and maximized space saving. For example, the avoiding hole 3821 is a hole connecting the bottom plate 211, and certainly, the avoiding hole 3821 may also be a U-shaped hole, so the invention is not limited thereto.
