[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1-3 As shown, a high-speed electric spindle precision bearing press-fitting device includes a base 1, on which a through hole 2, a first guide shaft 3, a bidirectional screw 4 and a second guide shaft 5 are provided. The through hole 2 is opened in the middle of the top of the base 1, the first guide shaft 3 is fixed to the rear end of the top of the base 1 through a shaft seat, the bidirectional screw 4 is installed to the front end of the top of the base 1 through a bearing seat, and the bidirectional screw 4 is symmetrically connected with a support slider 6 through a thread, the rear end of the support slider 6 is sleeved on the first guide shaft 3, and the second guide shaft 5 is fixed to the top corner of the base 1 through screws. A fixed seat 7 and a transmission seat 8 are provided on the second guide shaft 5. The fixed seat 7 is fixed to the top of the second guide shaft 5 by screws, and the transmission seat 8 is sleeved on the second guide shaft 5. A hydraulic cylinder 9 is fixed to the middle of the top of the fixed seat 7 by screws. The piston rod of the hydraulic cylinder 9 passes through and extends to the bottom of the fixed seat 7 and is fixed to a sleeve 10 by screws. An adjusting screw 11 is welded to the bottom of the sleeve 10, and the lower end of the adjusting screw 11 is connected to an extension screw sleeve 12 by threads.
