<p>The tyre-changing machine (1) comprises a bearing frame (2), at least a supporting element (3) of a wheel (R) associated with the frame (2) and which may be operated in rotation around a relative axis, at least a base element (4) connected to the frame (2) and with which is associated a tool (5) moving alternately between two distinct predefined work positions, the supporting element (3) and the base element (4) being reciprocally mobile; removable locking means (10) for locking the tool (5) to the base element (4) in each of the work positions, wherein the locking means (10) comprise at least one locking element (11) movable at least with respect to the base element (4) and fluid- dynamic control means (12) operatively connected to the locking element (11) and which may be operated to move the locking element itself between a release configuration, in which it allows the tool (5) to shift with respect to the base element (4), and an engagement configuration, in which it cooperates with the tool (5) and with the base element (4) to lock them reciprocally in the work positions.</p> |
