  • Publication number: 20240075569
    Abstract: A system and method for transferring a part being machined by a machine from a first fixture to a second fixture so that an un-machined side of the part can be exposed for machining, where the first fixture is secured to a first actuator and the second fixture is secured to a second actuator. The method includes securing the part to the first fixture, operating the first actuator so that the part is able to be machined on sides of the part except a side of the part coupled to the first fixture, and machining the part while the part is secured to the first fixture. The method operates the first actuator and the second actuator so that the part secured to the first fixture is aligned with the second fixture, and secures the part to the second fixture and releases the part from the first fixture.

  • Patent number: 11273531
    Abstract: A smart coolant pump for a robotic or computer-controlled machine. The smart pump uses a servo motor rather than a conventional industrial motor such as an induction motor. The smart pump has inherent torque and speed sensing, and a controller integrated with the computer-controlled machine controller. The motor torque/speed sensing and coolant pressure/flow sensing enable immediate detection of any anomalous conditions such as low coolant level or coolant port blockage. The smart pump can be configured to run at a certain speed and provide a specific coolant pressure and flow rate for each machining operation performed at the station, and to run at a very low speed between machining operations. This speed configurability saves energy and allows the pump and coolant to run at lower temperatures compared to conventional constant-speed coolant pumps.

  • Patent number: 11163295
    Abstract: A method and apparatus for controlling a continuous machining process includes a robot, a machining tool, a table, and a raw parts supply mounted inside a machining cell enclosure. The table has first and second vises for holding parts. The machining tool is operated to machine a raw part in one of the vises while the robot is operated to pick a machined part from the other vise and then place another raw part into the other vise. The table can be fixed or rotatable. The robot places the picked machined parts on an exit conveyor to remove the machined parts from the enclosure.

  • Patent number: 7967354
    Abstract: A mixed size product end of arm tooling is used in conjunction with a robot to pick mixed size product and place the product onto a pallet or layers resting on top of a pallet. The end of arm tooling includes two center rails/forks mounted to a base. Two outer rails/forks are mounted to linear bearings that guide the outer rails/forks when moving inwardly or outwardly from the center rails for pre-sizing to the product. Pusher arms are formed of two outer pusher arms and one center pusher arm. These pusher arms are attached to linear bushings that guide the pusher arms forward and backward. The pusher arms push off the product simultaneously as the robot is withdrawing the rails.
