摘要： A brake mechanism has a brake disk, multiple clutches, and multiple brake assemblies. The brake disk is coaxially connected to a rotatable work table. The multiple clutches are capable of clamping the brake disk. The multiple brake assemblies correspond in position to the multiple clutches. Each one of the multiple brake assemblies has a housing, an abutting shaft inserted in the housing, and multiple elastic units received in the housing and abutting against the abutting shaft. The multiple abutting shafts of the multiple brake assemblies abut against the brake disk for stopping the work table from rotating. A hydraulic system applies hydraulic pressure inside the multiple housings of the multiple brake assemblies and forces the multiple abutting shafts to depart from the corresponding clutch, making the work table rotate again.

摘要： A composite processing machine with an automatic swiveling composite turret device. Transmitting and releasing of rotational force to a rotating tool is automatically switched between indexing and locked securing. Included is a clutch-action-coupled rotational force transmission/release switching mechanism (10). A common motor (9) is the drive source for a rotation drive mechanism (7) for transmitting rotational force to a rotating tool (5) and a swivel drive mechanism (8) for swiveling a turret (3). Transmission of rotational force of common motor (9) to rotation drive mechanism (7) is released when turret (3) is slid along swivel shaft part (2) to unlock clutch device (4) and enable turret (3) to swivel, and rotational force of common motor (9) is transmitted to rotating tool (5) when turret (3) is slid back to lock and secure clutch device (4) in an indexed position of turret (3).

摘要： A circular dividing table includes a brake assembly, in which the piston return spring urges the annular piston with the bottom face of its annular groove. The piston retracts backward and the floating pad return plate contacts the bracket extending inward within the cylindrical bore of the floating pad, thus urging the floating pad backward. Due to the backward displacement of the floating pad, the floating pad is forced to retract from the brake disc. Using a circular dividing table equipped with such a brake assembly, it is possible to release the clamping members forcibly and to make the action of clamping or unclamping precise and conducted with a high responsive speed.
