  • Patent number: 11819969
    Abstract: A robotic tool changer for machining center includes a drive mechanism, a first motor, and a rotary seat which are mounted on a body. The drive mechanism includes a first rotating shaft, a second rotating shaft, a first swing arm, a second swing arm, and a linkage member. The first rotating shaft and the second rotating shaft are arranged in parallel. The first swing arm is connected to the first rotating shaft while the second swing arm is connected to the second rotating shaft. Two ends of the linkage member are pivotally connected to the first swing arm and the second swing arm respectively. An end of the second rotating shaft is fixed to the rotary seat. Thereby, when the first motor drives the first rotating shaft to rotate, the rotary seat is driven to turn over.

  • Patent number: 11583967
    Abstract: 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.

  • Patent number: 11548109
    Abstract: 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.
