The device allows the operator to place the bearing on the placement table, and then turn on the first motor, the second motor and the hydraulic rod through the external controller, the first motor drives the forward and reverse screws to start rotating through the bearing seat, the forward and reverse screws drive the threaded seat to start moving in opposite directions, the threaded seat drives the pulley to slide in the housing, and at the same time the threaded seat drives the fixed column to start moving, the fixed column drives the fixed rod to start moving, the fixed rod drives the arc-shaped clamp to start moving, so that the arc-shaped clamp clamps the bearing on the placement table.

[0004] However, in the existing bearing chamfering method, the bearing is fixed by means of a forward and reverse screw sliding screw, which causes one side of the bearing to be covered, and only a single-sided bearing can be chamfered, resulting in low efficiency of bearing chamfering. Utility Model Content

[0011] Preferably, the lower pressure plate is convex and is used to support and limit the flange bearing to be chamfered.

[0012] The utility model proposes a chamfering tool for flange bearings, which has the beneficial effects that: the utility model can realize chamfering operations on the upper and lower surfaces of the flange bearing at the same time by providing an upper chamfering knife and a lower chamfering knife, thereby improving efficiency; the utility model can realize clamping the upper and lower surfaces of the flange bearing by providing an upper pressure plate and a lower pressure plate, so as to perform chamfering operations on the upper and lower surfaces of the flange bearing at the same time.
