Abstract
The utility model discloses a truck wheel set positioning device, which comprises a base. The upper part of the base is provided with a lower semi-circle half positioning block; the lower semi-circle half positioning block is connected with an upper semi-circle half positioning block; a side positioning device is arranged at the lower part of a half positioning block of the base and comprises an oil cylinder, a piston, a piston rod, a wedge rod, a guide cylinder, a guide sleeve, a disk spring, a coupling spindle and a side pressure wheel; the oil cylinder drives the guide sleeve to move in the guide cylinder through the piston, the piston rod and the wedge rod; and the guide sleeve drives the coupling spindle and the side pressure wheel to move through the disk spring. In the truck wheel set positioning device, a top circle without disassembling a bearing of the two ends of the wheel set is used as a positioning reference; the wheel set bearing is arranged on the lower semi-circle half positioning block; the top circle of the bearing is fully enveloped by the upper and the lower semi-circle half positioning blocks during cutting and machining; the wheel set is clamped so as to avoid producing vibratory motion; therefore, the wheel set is accurate, stable and reliable to position, and the axial and radial runout of the wheel set is effectively controlled during cutting and machining so as to guarantee the machining quality of the flange and the tread.
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.
The utility model content
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.
The technical solution of the utility model is: a kind of truck wheel 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, carve bar, fairlead, guide cylinder, disk spring, coupling spindle, the side pressure wheel, oil cylinder, piston, piston rod is to being vertical direction, the axial of guide cylinder is horizontal direction and the axially parallel of breathing out the volt locating piece, be provided with fairlead in the guide cylinder, have skewed slot in the fairlead, carving bar one end is inserted in the skewed slot, the other end links to each other with piston rod by pin, and an end of coupling spindle is inserted in the guide cylinder, and the other end links to each other with the side pressure wheel by pin.Disk spring and adjustment screw are set between fairlead and the coupling spindle, and adjustment screw one end links to each other with the fairlead screw thread, and the other end is stuck in the coupling spindle end recesses by ring flange.
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.
