[0006] As the preferred technical solution of the utility model: the driving mechanism includes a forward and reverse motor, which is installed on the top surface of the top plate, and a through hole is opened on the top plate. The output shaft of the forward and reverse motor passes through the through hole, and the end of the output shaft of the forward and reverse motor is coaxially connected with a gear, and a rack is installed on the side of the connecting rod close to the gear, and the gear is meshed with the gear.

[0007] As a preferred technical solution of the utility model: a sponge protective pad is installed at the bottom of the pressing plate.

[0008] By adopting the above technical scheme, the beneficial effects of the utility model are: the utility model has a simple structure and ingenious design. The shell is first pressed and fixed by the set pressure plate, which can effectively avoid the shell from deviating during the press-fitting process and affecting the press-fitting effect. Then the floating pressure head is used to press the tapered bearing efficiently and accurately, and it is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
