The invention discloses a
bushing press-fit bolt and a press-fit method thereof. The
bushing press-fit bolt is used for press fitting bushings into pressing sleeve holes of workpieces to be pressed and sleeved, and the center of each
bushing is provided with a bushing hole. The bushing press-fit bolt comprises a pressing sleeve screw, a nut, two pressing sleeves and two
flange discs; the pressing sleeve screw comprises a
screw head and a screw rod, the two pressing sleeves comprise a first pressing sleeve and a second pressing sleeve, and the two
flange discs comprise a head
flange and a
tail flange; the head flange, the first pressing sleeve, the second pressing sleeve, the
tail flange and the nut are sequentially and coaxially installed on the screw rod from the
screw head in a sleeving mode, and the outer
diameter of each flange disc is larger than that of each pressing sleeve. By means of the structure and method, two bushings can be simultaneously press fit through one-time press-fit, the
abrasive resistance of the press-fit bolt is good, the pressing sleeves and threads are all not prone to damage, the service life is long, the press-fit yield is high, the press-fit uniformity and centering performance are good, and the manufacturing cost is low.
