Preferably, the lifting component comprises a screw motor arranged at the top of the inner cylinder, a ball screw of the screw motor penetrates through the inner cylinder and is in threaded connection with a lifting seat, the lifting seat is in sliding connection with the inner cylinder wall of the inner cylinder, and the lifting seat is fixedly connected with the mounting head. The effect of this scheme is can steadily reciprocate in the inner tube through motor drive lift seat to drive the installation head and remove and impress the bearing in/extract the bearing frame.

Preferably, the inner cylinder wall of the inner cylinder is horizontally provided with a sliding groove, a guide sliding block is slidably mounted in the sliding groove, and the guide sliding block is fixedly connected with the side wall of the lifting seat. The effect of this scheme is that the stability of installation head up-and-down movement is improved.

Preferably, the mounting head and the lifting seat are coaxially arranged. The effect of this scheme is that improves bearing clamping stability.

Preferably, the top of the adjusting screw rod is vertically provided with a guide groove, and the lower part of the ball screw rod is movably arranged in the guide groove in a penetrating manner. The effect of this scheme is can be used for the bearing of centre gripping different length sizes.

Preferably, the horizontal blade and the mounting head have the same diameter. The effect of this scheme is that the centre gripping stability of bearing inner race and outer lane is improved simultaneously.

Preferably, the lower surface of the mounting head is provided with a circle of limiting groove. The effect of this scheme can carry out spacingly to the bearing inner race.

Has the advantages that: compared with the prior art, the utility model provides an adjustable bearing installation device, on simple to operate's basis, guaranteed the safe steadiness of installation work, can finely tune the use according to the size of different bearings to can fix the inner circle and the outer lane of bearing simultaneously, make the bearing atress more even, effectually ensured that the bearing can not suffer the damage because of external force is too big, thereby prolonged life, guaranteed the installation accuracy of bearing, still effectively improved the installation effectiveness of bearing.
