MACHINE FOR REMOVING AND FITTING WHEEL TYRES FOR VEHICLES

摘要

The machine (1) for removing and fitting wheel tyres for vehicles comprises a bearing structure (2), a clamping device (5) of a rim (C) of a wheel (R) for vehicles, associated with the bearing structure (2) and rotatable around a first axis of rotation (X1), a tool-carrying arm (6) associated movable with the bearing structure (2) and having a removing/fitting tool (7) of a tyre (P) from/onto the rim (C), an auxiliary arm (8) having a bead pressing tool (9, 10) able to facilitate the removing/fitting operations of the tyre (P) from/onto the rim (C), wherein the auxiliary arm (8) is associated rotatable with the bearing structure (2) around a second axis of rotation (X2) substantially parallel to the first axis of rotation (X1), in correspondence of a hinging point (14) arranged above with respect to a resting plane of the rim (C) defined by the clamping device (5), and wherein the auxiliary arm (8) can be positioned between a work position, wherein the bead pressing tool (9, 10) is able to be engaged on a portion of the tyre (P), and a rest position, wherein the auxiliary arm (8) is retracted and substantially spaced from the clamping device (5), and wherein the machine (1) comprises an automatic positioning apparatus (20) of the auxiliary arm (8) in the rest position.
