Abstract
A tire truing machine that has a continuously orbiting band saw moving across a tool guide that has a plurality of adjustable guide members that can be shaped to the profile of the tire to be trued or contoured to a preexisting cam profile with the cumulative guide members defining an arcuately shaped recess or guide which positions the cutting edge of a band saw adjacent to the tread of a pneumatic tire in a precise profile control. The tire is chucked and rotated as the band saw operates on the tread surface or portions thereof to the profile set or adjusted.
Claims26
An apparatus for truing tires comprising a support means, chuck means mounted on said support means for supporting a tire, drive means operatively connected to said chuck means for rotating said chuck means and a tire mounted thereon about a central axis of rotation, a carriage mounted on said support means for movement toward and away from said central axis, power means connected to said carriage for moving said carriage, pulley means mounted on said carriage, an endless band saw mounted on said support means and trained about said pulley means for movement thereon, said band saw having a forwardly disposed cutting edge, tool support means mounted on said carriage, said tool support means having guide means thereon, the outer edge of said guide means operative to guide said band saw in the shape of a tire profile, cam means operatively connected to said guide means for shaping the profile thereof to corresponding shape said band saw to maintain said band saw a predetermined distance and shape from said central axis during passage through said tool support means.
A tire truing machine comprising support means, chuck means mounted on said support means for supporting a tire for rotation about a central axis, motive drive means connected to said chuck means for rotating said chuck means and a tire mounted thereon about said central axis, a carriage mounted in said support means for movement toward and away from said central axis, power means connected to said carriage for moving said carriage, a circular endless band-saw mounted on said carriage, drive means connected to said band-saw for driving said band-saw through an orbital path, tool support means mounted on said support means, tool support means having guide means thereon, said guide means having a plurality of guide members, each of said guide members adjustable toward and away from said central axis, cam means on said guide means connected to said guide members for positioning said guide members relative to each other, and each of said guide members having a guiding portion on its outer end portion that are cooperative with adjacent guiding portions to provide a guiding recess to guide said band-saw in a portion of its path to trim the outer peripheral surface of a tire as it is held and rotated by said chuck means.
A tire truing machine comprising support means, chuck means mounted on said support means for supporting a tire for rotation about a central axis, motive drive means connected to said chuck means for rotating said chuck means and a tire mounted thereon about said central axis of rotation, a circular endless band saw mounted on said support means, drive means connected to said band saw for driving said band saw through an orbital path, tool support means mounted on said support means, said tool support means having guide means thereon for engaging a portion of said band saw to guide said band saw in a portion of its orbital path to trim the outer peripheral surface of a tire rotated by said chuck means, cam means operatively connected to said guide means for shaping said guide means into a predetermined curvilinear pattern for guiding that portion of the orbital path of said band saw for cutting a tire.
An apparatus for truing tires comprising a support means;
- chuck means mounted on said support means for supporting a tire;
- drive means operatively connected to said chuck means for rotating said chuck means and a tire mounted thereon about a central axis of rotation;
- a carriage mounted on said support means for movement toward and away from said central axis;
- power means connected to said carriage for moving said carriage;
- pulley means mounted on said carriage;
- an endless band-saw mounted on said support means and trained about said spaced pulleys for movement thereon;
- said band-saw having a forwardly disposed cutting edge, tapering side edges and side portions merging with said tapering side edge;
- tool support means mounted on said carriage;
- said tool support means having guide means;
- the outer edge of said guide means operative to shape said band-saw into a non-linear contour of the shape of a tire profile;
- roller means cooperative with said guide means and engageable with said band-saw to maintain said band-saw a predetermined distance from said central axis during passage through said tool support means;
- and said roller means includes pairs of rollers with adjacent champered peripheral side portions rolling engaging said tapering side edges of said band-saw.
A tire truing machine comprising support means, chuck means mounted on said support means for supporting a tire for rotation about a central axis, motive drive means connected to said chuck means for rotating said chuck means and a tire mounted thereon about said central axis, a carriage mounted on said support means for movement toward and away from said central axis, power means connected to said carriage for moving said carriage, a circular endless band-saw mounted on said carriage, drive means connected to said band-saw for driving said band-saw through an orbital path, tool support means mounted on said support means, tool support means having a plurality of guide segments, each of said segments moveable toward and away from said central axis, lock means on said tool support means and connected to said guide segments for locking the adjusted positions of said guide segments relative to each other, and each of said segments having a projection in its outer end portion, the projections of all of said segments are cooperative to define a recess that guides said band-saw in a portion of its path to trim the outer peripheral surface of a tire as it is held and rotated by said chuck means.
An apparatus for truing tires comprising a support means, chuck means mounted on said support means for supporting a tire, drive means operatively connected to said chuck means for rotating said chuck means and a tire mounted thereon about a central axis of rotation, a carriage mounted on said support means for movement toward and away from said central axis, power means connected to said carriage for moving said carriage, pulley means mounted on said carriage, an endless band-saw mounted on said carriage and trained about said spaced pulleys for movement thereon, said band-saw having a forwardly disposed cutting edge, tool support means mounted on said carriage between said spaced pulleys, said tool support means having guide means moveable linearly toward and away from said axis of rotation, cam means on said tool support means operative to abut said guide means to shape the outer edge of said guide means to the profile of a tire to be trued, said guide means including means operative to engage said band-saw and maintain said band-saw a predetermined distance from said central axis during passage through said tool support means, adjusting means operatively connected to said cam means for adjusting the lateral position of said cam means and shifting the contour of said guide means in responses thereto.
