A chain-type tool magazine includes a main body, a track, a chain, and a driving mechanism. The track is coupled to the mounting surface of the main body and provides a running route which includes a physical support segment and at least one vacant running segment. The chain is formed by a plurality of tool chains connected in series and is driven by the driving mechanism to run around the running route. When each of the tool chains of the chain passes through the physical support segment, each of the tool chains is in contact with the physical support segment. When each of the tool chains of the chain passes through the vacant running segment, each of the tool chains is not in contact with the track. With a discontinuous broken-track type design of the track, the cost can be reduced.

A tool magazine as a conveyance device includes a first conveyance unit that conveys a plurality of tools along a first route, a second conveyance unit that conveys a plurality of tools along a second route, and a cover body. A first opening used to attach and detach the tool in a first section of first route and a second opening used to attach and detach the tool a third section of second route are provided in cover body. A second section of first route is located between first section of first route and second conveyance unit in a direction in which first conveyance unit and second conveyance unit are arranged. A fourth section of second route is located between third section of second route and first conveyance unit in the direction in which first conveyance unit and second conveyance unit are arranged.

A tool holder holding and loosening device of chain-type tool magazine of a machine tool is disclosed. A locking mechanism is disposed on a rear end of each of sockets in a tool magazine. The locking mechanism is adapted to abut against an end of a tool holder mounted in the socket, thereby to prevent the tool holder from accidentally loosing. A tool loosening device is disposed on a predetermined position of the chain-type tool magazine. The tool loosening device is adapted to unlock the locking mechanism of the tool magazine passing through the predetermined position, so that the tool holder could be easily taken out of the socket.

The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

A tool change unit includes a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base. Each arm body includes a position-returning element, a gripping element, and an actuation element. The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.

The present disclosure relates to a tool holder to receive and lock a tool taper on a tool magazine, an unlocking device to unlock a tool taper that is received and is locked in a tool holder of this type, and a tool magazine for a machine tool comprising one or more tool holders of this type and an unlocking device of this type.

A conveyance chain comprises a plurality of link plates alternately coupled and conveying plural tool pots each holding a tool. The plurality of link plates include an inner link plate and an outer link plate each including a rotation stop hole that stops a rotation of the tool pot and a rotation permit hole located upstream from the rotation stop hole with respect to a conveyance direction that permits a rotation of the tool pot. The plurality of tool pots includes a first tool pot and a second tool pot, the first tool pot is inserted through a rotation stop hole of the inner link plate and a rotation permit hole of the outer link plate, and adjacent to the first tool pot, the second tool pot is inserted through a rotation permit hole of the inner link plate and a rotation stop hole of the outer link plate.

The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.
