A device for gripping an object (10) that includes a main body (12) having a first and a second endplate (12A, 12B), a baseplate (26), at least one guide rail (28A, 28B), and a first jaw and a second jaw (14A, 14B), each receiving the at least one guide rail. The device also includes a first pulley assembly and a second pulley assembly (16, 16) respectively attached to the baseplate and a chain loop (18) respectively attached to the first pulley assembly and the second pulley assembly. The chain loop includes a first chain length and a second chain length (32A, 32B) and a first link and a second link (34A, 34B) that attaches the first chain length and the second chain length. Each of the first link and second link include at least one dowel pin (36). The chain loop is attached to the first jaw and the second jaw by the at least one dowel pin of each of the first link and second link.

A locating pin assembly including a locating pin movable between extended and retracted positions. The locating pin includes a locating pin top having a top end and a bottom end, a locating pin base receiving the bottom end of the locating pin top, and a dowel pin configured to couple the locating pin top and locating pin base together. The locating pin assembly also includes a drive rod moveable relative to the locating pin. The drive rod includes a drive rod top having a top end and a bottom end, and a drive rod base partially housing the drive rod top. The locating pin assembly also includes a finger coupled to the drive rod and movable between extended and fully retracted positions, the finger is extended by the drive rod without movement of the locating pin, and the finger is rotatable from a first position to a second position.

A gripper for a robot has a gripper mechanism with a jaw motion input, and a motor speed reducer combination including a speed reducer and a motor. The speed reducer has a motion output. The gripper mechanism has a first pattern of mounting features arranged about the jaw motion input. The speed reducer has a second pattern of mounting features arranged about the motion output. The first pattern of mounting features and the second pattern of mounting features are arranged so that the motor reducer combination may be mounted to the gripper mechanism in at least four indexed positions about the motion output and the jaw motion input.


A sensor or switch mechanism (40) is connected to a gripper mechanism (20) and uses a pivotal cam link (60) connected to the driving mechanism (24, 30) of the gripper (20). A cam slot (62) in the cam link (60) is configured to convert linear reciprocal motion of the driving mechanism (24, 30) of the gripper (20) to amplified rotational motion of the pivotal cam link (60). A target (84) on the cam link (60) and a stationary sensor (80) positioned proximate to an arc described by the target (84) on rotation of the cam link (60) allows the sensor or switch mechanism (80) to distinguish between the gripper (20) properly gripping a single workpiece (200) and the gripper (20) improperly gripping no workpiece and/or two or more workpieces.

A locating pin assembly (20) including a locating pin (10) movable between extended and retracted positions. The locating pin includes a locating pin top (7) having a top end and a bottom end, a locating pin base (8) receiving the bottom end of the locating pin top, and a dowel pin (6) configured to couple the locating pin top and locating pin base together. The locating pin assembly also includes a drive rod (15) moveable relative to the locating pin. The drive rod includes a drive rod top (1) having a top end and a bottom end, and a drive rod base (2) partially housing the drive rod top. The locating pin assembly also includes a finger (5) coupled to the drive rod and movable between extended and fully retracted positions, the finger is extended by the drive rod without movement of the locating pin, and the finger is rotatable from a first position to a second position.

A rodless slide assembly (2) is provided illustratively having a longitudinally-extending cylinder (4), a carriage (6), a stop assembly (16), and a catch assembly (84). The longitudinally-extending cylinder comprises first and second ends and a path of travel extending therebetween. The carriage is slidable on the path of travel on the cylinder between the first and second ends. The stop assembly comprises a stop block (62) and is coupled to the carriage. In one embodiment the catch assembly includes a catch bar (96) and an actuator assembly (42). The catch bar is located adjacent the path of travel of the carriage. The actuator assembly selectively moves the catch bar to engage the stop block and stop the carriage when the carriage is positioned at a selected location on the path of travel.

A pin clamp (2) for clamping a workpiece includes a housing (4) having a longitudinal axis and a locating pin (6) extending through the housing. The locating pin (6) is sized to be positioned within an opening of the workpiece. A finger (10) is positioned adjacent to the locating pin (6) and movable in a transverse direction relative to the longitudinal axis to retain the workpiece on the locating pin (6). An exterior driving linkage (150) is configured to move the locating pin (6) in opposite directions along the longitudinal axis. A locking arrangement is carried by the housing. A sequence cam (54) is connected with the exterior driving linkage (150) thereby allowing axial movement of the exterior driving linkage (150) to be converted into transverse movement of the sequence cam. The sequence cam (54) includes an engagement surface which engages the locking arrangement to lock the locating pin (6) and the finger (10) against the workpiece upon retraction of the exterior driving linkage.
