The oil seal supporting head 3 is arranged at the front end of the machine base 1, and the oil seal 5 is placed on the oil seal supporting head 3. Among them, the part of the oil seal supporting head 3 in contact with the oil seal 5 is in a cylindrical structure, the oil seal 5 is sleeved on the outer wall of the circumferential direction of the cylindrical structure, and the outer diameter of the cylindrical structure is smaller than the inner diameter of the sleeve-shaped structure. In this way, the pushing head 2 can uniformly contact the oil seal 5, improving the flatness of pressing the oil seal 5 onto the target workpiece.

[0041] The first telescopic driving member 4 adopts an electric cylinder. The first telescopic driving member 4 is arranged on the machine base 1, and the telescopic end of the first telescopic driving member 4 is connected to the pushing transmission member. The telescopic end of the first telescopic driving member 4 expands and contracts relative to the fixed end, driving the pushing transmission member to move back and forth relative to the machine base 1. When the pushing transmission member moves forward relative to the machine base 1, the pushing head 2 pushes the oil seal 5 on the oil seal supporting head 3 forward to the target workpiece.

[0042] The pushing transmission member includes a first pushing transmission member 61 and a second pushing transmission member 62.
