Abstract
A wagon wheel pair positioning device comprises a base, a lower semicircle HAFU positioning block on the superior part of the base and connected with an upper semicircle HAFU positioning block, a side positioning device below the HAFU positioning block of the base, wherein the side positioning device comprises an oil cylinder, a piston, a piston rod, a tapered rod, a guide cylinder, a guide sleeve, a disk spring, a coupling shaft and a side pinch wheel and the oil cylinder moves in the guide cylinder through driving the guide sleeve by the piston, the piston rod and the tapered rod and the guide sleeve makes the coupling shaft and the side pinch wheel move by the disk spring. The excircles of the not-detachable bearings on the two ends of the wheel pair are used as positioning reference, the wheel pair bearings are set on the lower semicircle HAFU positioning block. During cutting processing, the lower semicircle HAFU positioning block and upper semicircle HAFU positioning block wholly enveloping the excircles of the bearings and clamping wheels make the bearings not vibrate, thus wheel pair is accurately, stably and reliably positioned and the axial looseness and radial run-out are effectively controlled during cutting processing the wheel pair, thus the processing quality of wheel rims and wheel treads are ensured.
Description
Technical field
The utility model relates to a kind of truck wheel to positioner.
Background technology
Along with the speed-raising of train, wheel is to the abrasion aggravation, and the reparation that truck wheel is right is had higher requirement.And to repair all be the technology that adopts bearing and end cap disintegration at existing right repair in shop, the station of truck wheel, with the centre bore location of wheel to two ends, clamp driven wheel by claw machining is carried out in rotation, so not only taken a lot of work but also time-consuming, can't satisfy speed-increase train again high accuracy, high efficiency reparation requirement.
Summary of the invention
The purpose of this utility model just provides a kind of truck wheel of axial float and circular runout can have control wheel to machining the time to positioner.
Truck wheel of the present utility model is to positioner, comprise base, base top is provided with lower half circle and breathes out the volt locating piece, lower half circle is breathed out the volt locating piece and is linked to each other with upper semi-circle Kazakhstan volt locating piece, the volt locating piece bottom, Kazakhstan of base is provided with the side positioner, the side positioner comprises oil cylinder, piston, piston rod, carves bar, guide cylinder, fairlead, disk spring, coupling spindle and side pressure wheel, oil cylinder by piston, piston rod, carve bar and drive fairlead and in guide cylinder, move, fairlead makes the motion of coupling spindle and side pressure wheel by disk spring.
Truck wheel of the present utility model to positioner utilization wheel to the cylindrical of two ends remaining on board bearing as the location benchmark, wheel set bearing is placed on lower half circle and breathes out on the volt locating piece, guaranteed that so every group of wheel is controlled on the centre of gyration of setting well to axial line, during machining, the circle that last lower half circle is breathed out volt locating piece composition carries out full envelope to bearing outer ring, and the micro-interference of 0.02 one 0.03mm is arranged, like this can pinch wheels to making it not produce vibration, can not destroy bearing again.Facts have proved that this positioner makes the right accurate positioning of wheel, stablized, reliably, effectively controlled axial float and circular runout when taking turns machining, has guaranteed the crudy of wheel rim and tread.
