  • Patent number: 11565400
    Abstract: A robot base assembly that supports a robot assembly above a floor. The robot assembly engages with a work piece having a locating component. The robot base assembly includes a base plate coupled to the floor, a support member slidably coupled to the base plate for linear displacement, a clamp assembly coupled to the support member, and a lock mechanism. The clamp assembly is movable between an engaged state and a disengaged state. In the engaged state the clamp assembly engages with the locating component. The lock mechanism is movable between a locked state and an unlocked state. In the locked state the support member is inhibited from linear displacement, and in the unlocked state the support member is permitted for linear displacement. The lock mechanism switches from the unlocked state to the locked state in response to the clamp assembly moving from the disengaged state to the engaged state.

  • Publication number: 20210154866
    Abstract: An apparatus for coupling a robot arm to a tool that is suspended by an ergonomic arm capable of supporting 3D motion of the tool within a working volume. The apparatus includes a tool sleeve configured to accept the tool, a freely rotating rotary fitting coupled to the tool sleeve, and a coupling that couples a distal end of the robot arm to the rotary fitting. When the tool is inserted into the tool sleeve, the tool is free to rotate around the rotational axis with respect to the robot arm, such that a motion of the distal end of the robot arm does not impose a torque between the robot arm and the tool around the rotational axis, and such that motion of the distal end of the robot arm repositions or reorients the tool within at least a portion of the working volume.

  • Patent number: 10766106
    Abstract: A simplified drive press system is operable to press-fit a pair of first workpieces into a second workpiece. The drive press system uses a simplified mechanical arrangement to translate an input torque into movement of a pair of drive arms toward and away from one another. Yokes of differing configurations may be attached to the drive arms to accommodate a variety of different workpieces. A nut runner may be used to supply a drive torque to the gear assembly and provide a controlled input torque and control the movement of the drive arms. An overall reduction may be utilized that balances a desired movement resolution with the desire to detect changes in input torque. The nut runner may be programmable to provide a desired movement of the drive arms while monitoring the input torque to detect when a fully press-fitted condition is realized.

  • Patent number: 10597007
    Abstract: A turntable includes a floor-level deck and a central support system configured to support the deck for rotation by a central area of the deck. The deck has an underside, a topside and, at its central area, a central relief opening from its underside to its topside. The central support system includes an above-floor stanchion that extends through the deck's central relief, and a topside rotary bearing mounted between the stanchion and the deck to carry the deck for rotation.

  • Patent number: 10414040
    Abstract: A robotic dolly transfer system configured to transport dollies includes a full dolly transfer system and an empty dolly transfer system. The full dolly transfer system and the empty dolly transfer system individually include a rail assembly and a carriage. The carriage is slidably attached to the rail assembly and includes a bottom surface that has a post extending outwardly. The rail assembly includes a rail actuator assembly having an actuator and a receiver attached to the actuator. The receiver includes an opening that receives the post such that the post floats within the opening to permit the carriage to move a predetermined amount independent from the receiver. The actuator is configured to displace the receiver such that receiver contacts the post to slide the carriage with respect to the rail assembly. A end effector is pivotally connected to a transfer arm assembly and is configured to engage the dolly.

  • Patent number: 10160628
    Abstract: A pneumatic lifting device includes a base, a first mast attached to the base, and a second mast attached to the base opposite the first mast. The first mast has a first rail extending therealong, and the second mast has a second rail extending therealong. A lift platform is operatively coupled to the base. The platform includes a first pair and a second pair of bearings coupled thereto so as to move in conjunction with the lift platform. The first pair of bearings is operatively coupled to the first rail so as to enable the first pair of bearings to move with respect to the first rail. The second pair of bearings is operatively coupled to the second rail so as to enable the second pair of bearings to move with respect to the second rail.

  • Patent number: 10053333
    Abstract: A platform lift configured for supporting the movement of items between a floor-level area and an elevated area includes a rigid, floor-level platform with two opposed sides, an above-floor mast arranged at each of the opposed sides of the platform, and a knuckle assembly coupling each mast to its respective side of the platform. The masts together support the platform for movement in a lifting direction normal to the platform, and each include an actuator coupled to its respective side of the platform that is selectively operable to impart lifting movement thereto in the lifting direction. The knuckle assemblies together permit the platform's rotation towards and away from the masts when their respective actuators impart different amounts of lifting movement to the opposed sides of the platform in the lifting direction.
