Embodiment

The utility model is described further below in conjunction with the accompanying drawings.

A kind of large-scale self-aligning bearing inner race R shape trimmers, include micro-adjustment device, swing arm, gyroaxis, crushing compensation Device, supporting plate stabilising arrangement and hydraulic pressure adjustable drawbar system；Micro-adjustment device includes handle 1, adjustment bar 2 and diamond pen 3； Swing arm is made up of the first swing arm 4 with the second swing arm into inverted L shape, and the first swing arm 4 is connected with the second swing arm by screw mandrel 5 with screw 6, Micro-adjustment device is connected by the first swing arm 4 with the second swing arm, and the second swing arm is made up of wobble plate 7, gusset 8；Under second swing arm End connection gyroaxis, gyroaxis include axle 9, and axle 9 is fixed on axle bed 10, and there is gland 11 upper end of axle bed 10；Gyroaxis and emery wheel Correcting compensation device is connected, and crushing compensation device includes feed screw 12, leading screw gland 13, slide plate chair 14 and slide plate 15, Feed screw 12 is fixed on slide plate chair 14, and slide plate chair 14 is connected with bottom plate 16；Supporting plate stabilising arrangement includes the He of supporting plate 17 Bent plate 18, bent plate 18 are connected with bottom plate 16；Hydraulic pressure adjustable drawbar system includes hydraulic pressure draw-bar 19 and oil cylinder 20, and hydraulic pressure draw-bar 19 is logical Hinge 21 is crossed with bottom plate 1 to be connected.

During work, start hydraulic pressure adjustable drawbar system, swing arm is pulled by hinge, swung centered on gyroaxis, second Swing arm controls amplitude of fluctuation, and amplitude of fluctuation controls emery wheel width size, and as abrasion of grinding wheel changes, the first swing arm can go up downward It is whole, change R value sizes by adjusting the first swing arm.

The utility model is not limited to above-mentioned embodiment, for the common skill of the utility model art Art personnel, without departing from the concept of the premise utility, some simple deduction or replace are made, should all be considered as belonging to this The protection domain of utility model.
