Problems solved by technology
If the concentricity of the pressure column and the positioning guide rod cannot be guaranteed, it will cause the pressure column to hit the hole wall of the second bearing hole 17 of the wheel 6, which will not only damage the bearing hole, but also fail to compress the bearing.
In addition, the height of the positioning guide rod is limited by the pressure column, and its positioning and guiding function is low

The invention relates to a wheel bearing press-mounting device, which is used for press mounting of bearings of the wheels. The device comprises a bottom plate of a press and an upper connecting plate of the press, wherein bottom plate is connected with the upper connecting plate through a fixed upright column; a positioning guide rod is fixed on the bottom plate of the press; a sliding column of the press is in sliding fit with the upper connecting plate of the press; an upper connecting pressing column is fixed at the lower end of the sliding column of the press; the axis of the upper connecting pressing column is consistent with that of the positioning guide rod; the diameter of the positioning guide rod is smaller than the inner diameter of a middle support rod; a shaft shoulder with the outer diameter smaller than the inner diameter of a first bearing hole is arranged at the lower part of the positioning guide rod; the positioning guide rod sequentially passes upwards through the first bearing hole, a central through hole and a second bearing hole and then extends out of the upper end face of a wheel hub; the extended end of the positioning guide rod is sleeved by a moving pressing sleeve; and the outer diameter of the moving pressing sleeve is smaller than the inner diameter of the second bearing hole. In the invention, the lengthened positioning guide rod and the moving pressing sleeve are jointed for press mounting of the two bearings of the wheels, so that the problem of loose pressing of the bearings is solved.
Description
technical field [0001] The invention relates to bearing assembling equipment, in particular to a wheel bearing press-fitting device. Background technique [0002] Such as figure 1 As shown, the two ends of the hub of the wheel 6 are respectively provided with a first bearing hole 16 and a second bearing hole 17, a first press-fit bearing 7 is installed in the first bearing hole 16, and a first press-fit bearing 7 is installed in the second bearing hole 17. There is a second press-fit bearing 9, and the two bearings are connected by an intermediate strut 8. The effect to be achieved after the press-fitting of the two bearings is completed: the end surface of the first press-fit bearing 7 needs to be in contact with the bottom surface of the first bearing hole 16 of the wheel 6, that is, this place is the press-fit datum plane A; the first press-fit bearing 7, The end face of the second press-fitted bearing 9 needs to be in contact with the two end faces of the middle strut ...
