    Abstract: A quick release extension rod with a positioning structure comprises a body, a return member, an inserting rod, an even number of balls, a positioning ring, a control ring assembly, four elastic members and a C-shaped retainer. The balls are disposed on the connecting head of the inserting rod, so that the radial interval between the socket and the connecting head of the base of the quick release extension rod can be evenly distributed. When the socket rotates, the arrangement of an even number of balls can reduce the possibility of the asymmetrical-center-of-gravity caused oscillation. The four elastic members are disposed between the control ring assembly and the body to push the socket can be abutted against the control ring assembly to delimitate the axial interval, which further stabilize the center of gravity of rotation of the socket while preventing the occurrence of oscillation of the socket.

    Abstract: A locking mechanism includes a lock housing and an activation shaft. The lock housing defines first and second axes, each being different than the other. The lock housing includes an inner mechanism housing wall, a hollow conduit defined by the inner mechanism housing wall, and a channel. The channel is defined by a portion of the inner mechanism housing wall and has first and second portions, where the first portion extends along the first axis and the second portion extends along the second axis. The activation shaft is at least partially surrounded by the hollow conduit and includes a shoulder protruding from the activation shaft towards the channel of the inner mechanism housing wall. In an unlock position, the shoulder is freely manipulatable within the first portion of the channel along the first axis, and in a lock position the shoulder is prevented from moving along the first axis.

  • Patent number: 8601667
    Abstract: In a robotic tool changer, a rotating cam surface ring having a plurality of surfaces formed therein urges a plurality of ball members in one tool coupling unit radially to contact a coupling surface in the other tool coupling unit. Mechanical energy captured and stored upon decoupling the units is used by an actuation mechanism, upon manual initiation, to at least partially automatically couple the two units by partially rotating the rotating cam surface ring. Further manual rotation of the cam member exerts a radial force through the ball members onto the coupling surface. A component of that force is directed by the coupling surface toward the opposite tool coupling unit, locking the two units together.

  • Patent number: 8533930
    Abstract: A manually actuated robotic tool changer includes a rapid coupling mechanism. The tool changer includes a master unit having a piston moveable along its axis between an unlocked position and a fully locked position, and a tool unit that is coupled to the master unit when the units are adjacent and the piston is moved to the fully locked position. A piston movement control mechanism selectively allows free axial motion of the piston between the unlocked position and a nearly locked position, when the control mechanism is actuated. The piston may be biased toward the locked position, allowing the master and tool units to be rapidly coupled by positioning the units adjacently, actuating the control mechanism to allow the piston to rapidly advance to a nearly locked position, releasing the control mechanism to restrict free axial motion of the piston, and manually advancing the piston to a fully locked position.

  • Patent number: 8500132
    Abstract: A manual robotic tool changer provides a compact, lightweight means to manually selectively couple a robotic tool, such as a surgical tool, to a robot arm. The tool changer includes numerous safety features to prevent inadvertent decoupling of the robotic tool. These include a dual-button handle locking mechanism operative to lock the tool changer closed in the fully coupled position, and requiring simultaneous actuation of both of two latch buttons to unlock; a one-way clutch mechanism that prevents rotation of the coupling mechanism towards the decoupled position, unless the handle is actuated to unlock the tool changer; and a spring biasing the tool changer to an at least partially coupled state when no force is applied to the handle, thus requiring a positive force against the spring, moving the handle to a fully open position, to insert or remove a robotic tool.

  • Patent number: 8500358
    Abstract: A quick disconnect system including a matable coupling and post. The coupling includes a base, a pair of pins, a jacket and a biasing means. The base defines a longitudinally extending bore. The pair of pins are radially repositionable relative to the bore and extend tangentially along opposite sides of the bore. The jacket cooperatively engages the base and the pins whereby longitudinal repositioning of the jacket as between a first stop position and a second stop position effects radial repositioning of the pins. The biasing means biases the jacket towards the first stop position. The post has a flanged head on the distal end of a shaft for cooperatively engaging the pins to achieve connection of the coupling and the post.

  • Patent number: 8403589
    Abstract: A paint gun assembly including a spray head and a connecting manifold. The spray head includes a bore terminating in a radially extending space of gradually increasing radius. The bore receives a shaft that has an axially extending bore which connects with radially extending bores in which balls are contained. The shaft also contains a plunger with a rounded end, engaging the balls. When forced into the axial bore, the plunger forces the balls into the radially extending bores and out into the tapered, radially extending space. The plunger engages a cam which is exposed at a surface of the manifold body and includes a hexagon drive to adjust the angular rotation of the cam using a suitable key. The manifold body provides a recess for receiving a retaining pin, whose end is received in the cam guide profile. Axial movement of the cam is resisted by a compression spring.
