Abstract
A boring apparatus and method for in-situ repair of motor vehicle axles includes a universal mounting plate assembly for attachment to a vehicle axle, both longitudinal (on-axis) and transverse (radial) adjustment assemblies, a bearing assembly and a boring bar and drive assembly having a pair of motor drive units for rotating (speed) and axially advancing (feed) the boring bar. The longitudinal and transverse adjustment assemblies facilitate use of the boring apparatus on a wide variety of vehicle and truck axles from virtually all manufacturers to repair broken axles or damaged bearing surfaces.
Claims20
An apparatus for boring vehicle axles comprising, in combination,
- a plate having an aperture adapted to receive a portion of a vehicle axle, a plurality of lugs adjustably secured to said plate and adapted for attachment to a feature of such vehicle axle;
- an adjustment assembly having a first end face disposed adjacent said plate, a second end, and a plurality of opposed pairs of adjustment devices adjacent said second end having axes normal to one another;
- spacer means disposed between said plate and said end of said adjustment assembly,
- a bearing assembly having a first end and a second end, said first end of said bearing assembly operably disposed adjacent said plurality of opposed pairs of adjustment assemblies, said bearing assembly including at least one bearing for stabilizing a boring bar, and
- a boring bar drive assembly secured to said second end of said bearing assembly and adapted to advance, retract and rotate a boring bar.
An apparatus for boring vehicle axles comprising, in combination,
- a plate having an aperture adapted to receive a portion of a vehicle axle defining an axis, a plurality of adjustable lugs secured to said plate and adapted for attachment to a feature of such vehicle axle;
- a radial adjustment assembly having a plurality of opposed pairs of adjustment devices having axes of motion normal to said axis of said vehicle axle, said adjustment assembly having a first end disposed adjacent said plate and a second end;
- an axial adjustment assembly disposed between said plate and said first end of said radial adjustment assembly,
- a bearing assembly having a first end and a second end, said first end of said bearing assembly positioned operably adjacent said plurality of opposed pairs of adjustment devices,
- said bearing assembly including at least one bearing for stabilizing a boring bar,
- a boring bar supported in said bearing assembly and adapted to bore such vehicle axle;
- and
- a drive assembly associated with said boring bar and having a first drive motor for advancing said boring bar and a second drive motor for rotating said boring bar.
An apparatus for repairing vehicle axles comprising, in combination,
- a plate having an aperture adapted to receive a portion of a vehicle axle, a plurality of mounting ears adjustably secured to said plate and adapted for securement to a feature of such vehicle axle;
- a radial adjustment assembly having at least two pairs of opposed adjustment devices having axes of motion normal to one another, said adjustment assembly having a first end disposed adjacent said first plate and a second end;
- axial adjustment means disposed between said plate and said first end of said radial adjustment assembly for fixing axial separation between said plate and said first end of said radial adjustment assembly,
- a bearing assembly having a first end and a second end, said first end of said bearing assembly disposed operably adjacent said opposed pairs of adjustment devices,
- said bearing assembly including at least one bearing for stabilizing a boring bar,
- a boring bar supported in said bearing assembly and having a cutting tool adapted to bore such vehicle axle;
- and
- a drive assembly associated with said boring bar and having a first drive motor for advancing said boring bar and a second drive motor for rotating said boring bar.
