Composite axle box positioning device

The utility model provides a composite axle box positioning device, which is characterized in that a composite positioning structure combining a steel spring and a rubber spring is adopted to realize gapless and non-abrasive limiting and assembly of axle box positioning, as well as improve transverse and longitudinal rigidity and provide proper vertical rigidity of the axle box positioning device. The composite axle box positioning device comprises a positioning guide pillar vertically connected to a frame via a positioning bolt, a lower clamping plate and an upper clamping plate disposed on an axle box body installation seat, and a steel spring clamped between the lower clamping plate and the upper clamping plate. The lower clamping plate is provided with a groove surrounding the positioning guide pillar, and a rubber spring is sleeved in the internal of the groove and on the positioning guide pillar. The rubber spring is formed by sulfuration processing of rubber and a steel plate and pressed in the lower c
