摘要:
Apparatus for inflating a wheel-mounted tire on a high production basis comprises a platen supported on a frame beneath an inflation head on which the wheel-mounted tire is received. The platen has internal air passages opening opposite a fixed support plate of the frame through which pressurized air is directed to selectively float the platen above the support plate to facilitate near-frictionless horizontal movement of the platen in all radial directions. A centering device locates the wheel-mounted tire precisely in line with the inflation head after which the air is discontinued to lower the platen back onto the support plate. The inflation head is then operated to inflate the tire. The platen is refloated and centered in a home position by a platen centering device.

A tire mounting apparatus for mounting a flexible tire on a rim includes a robot having at least one articulated joint and a wrist. The robot is moveable with at least three degrees of freedom along a selectable one of a plurality of programmable predetermined paths. A central processing unit selectively executes any one of the plurality of paths stored in memory. A bead mounting tool is attachable to the wrist of the robot for movement along the selected one of the plurality of programmable predetermined paths of the robot. The tool is orientatable with at least three degrees of freedom independent of the selected one of the plurality of programmable predetermined paths. A workpiece support positions the rim in a predetermined location with respect to the robot and positions the tire in a predetermined orientation with respect to the rim. A signal is generated and sent to the robot corresponding to a size of the rim and tire combination to be assembled. The central processing unit selects one of the plurality of predetermined paths corresponding to the rim and tire size combination. The robot includes one or more sensors for measuring load on the articulated joint and wrist during a tire mounting cycle. The control program includes a sensor monitoring function for stopping movement of the tool in response to a load greater than a predetermined value. A clamp member prevents rotation of the tire with respect to the rim as the tool works a bead of the tire over the rim.

An easy to use retrofit apparatus or OEM machine difficult to mount tire changer for use in tire mounting and demounting operations and bead loosening operations which eliminates damage to tire sidewalls and the rim of wheels.
摘要:
In order to rationalize and make profitable the use of machines for positing the beads of tires for finishing mounted, deliverable assemblies, the machine according to the invention comprises two plates (10), one upper and one lower, each provided with at least two cylindrical rings (4), of different diameters and axially movable independently, and also means (3, 5, 7, 11, 12, 13) which, according to the dimension of the tire of the mounted assembly E to be treated, permit the selection of the appropriate rings (4', 4"), and the adjustment of the axial distance necessary between rings, and sufficient to obtain the desired compression of the sidewalls of the tire, after application of said rings to the sidewalls of the tire of the assembly E.

A quick change assembly for connecting a mount/dismount head to a swing arm of a rim holding tire changer. The rim holding tire changer includes a swing arm mounted for swinging the mount/dismount head into and out of engagement with a tire on the table of the rim holding tire changer. The quick change assembly is connected to the end of the swing arm. The quick change assembly acts to connect the mount/dismount head to the end of the swing arm in a pre-aligned rotatable orientation. One end of the connector is adapted to mate with the mount/dismount head. That end includes an adjuster for adjusting the aligned relation of the mount/dismount head with respect to the connector end. The other end of the connector includes a locator for locating the pre-aligned rotatable orientation with respect to the swing arm end. Such locator may be a dowel inset in the swing arm end and a slot in the end of the connector which mates to the swing arm. A bore-counter-bore would be sufficient as well. The quick change assembly also includes a connector for preventing vertical displacement between the assembly and the mount/dismount head, thus forming a tool head. An attachment for quickly detaching and reattaching the assembly, and hence, the tool head, to the swing arm is also included in the connector assembly. A typical tool head for an automotive rim is disclosed, as is a typical plastic tool head for use with decorative rims, and a typical tool head for use with an RTV or motorcycle rim.
摘要:
A machine for removing and mounting tires from and onto respective wheel rims has a base (1;20), a platform (3;22) rotating on the base, and a column (7; 26) which extends vertically upwards from the base to the side of the platform and supports, one following the other, two mutually slidable elements one of which carries at its end a tool (15; 33) which is to operate on the tire bead. The element which supports the tool is secured to the center of the wheel rim.
摘要:
An implement for facilitating the mounting of tires onto respective wheel rims, typically for tire removal machines including a horizontal self-centering unit (4) and a projecting horizontal arm (6), on the end of which there slides a height-adjustable vertical rod (8) which is provided lowerly with a tool (9) for mounting and removing tires (10). The tire mounting machine includes a shaped arm which at one end is provided with a projecting profiled head (18), and at its other end is mounted rotatable and slidable on said vertical rod (8) so as to occupy a raised rest position and a lowered working position in which said head can be inserted between the edge of a wheel rim (44) locked by the self-centering unit and the bead (110) of the tire (10) to be mounted, the head resting against that wheel rim part (42) forming the seat for receiving the bead.
摘要:
Apparatus for use in mounting tires on and removing tires from wheel rims including wheel supporting means comprising a plurality of gripping arms and claws, each claw being provided with an extension block for supporting the adjacent bead and lower sidewall of the tire on the wheel rim clear of its bead seat on the rim. The extension block may be detachable from each claw, or pivotally secured to it and held in an operative position by self locking means.
摘要:
A device for removing heavy duty tires from their wheel assemblies which employs a base, vertical press members mounted thereon and a movable platform which operates to force the rim of the wheel upwardly of the flange thereby reducing the pressure on the wheel assembly, and a lifting assembly for removing the annular bead seat band from the wheel assembly thereby rendering the tire and wheel assembly in condition for easy demounting.
