A tool changerwith a master halfand tool half. A securing mechanism has a claspand a cam. The claspsmove between a release position and a grasping position. In the grasping position, the masterand tool halvesare secured together with one another. The cammoves the claspsbetween the release and grasping positions. From a release position, the master halfengages the tool half. The master halfmoves laterally with respect to the tool half. This, in turn, moves the cam, and thus the clasps, from their release positions to their grasping positions. In the grasping position, the claspsgrasp the tool half, the cam locksin its grasping position and the masterand toolhalves secure with one another.

The claspsmove between a release position and a grasping position. In the grasping position, the masterand tool halvesare secured together with one another. The cammoves the claspsbetween the release and grasping positions. From a release position, the master halfengages the tool half. The master halfmoves horizontally with respect to the tool half. This, in turn, moves the camfrom its release position to its grasping position. In the grasping position, the claspsgrasp the tool half, the cam locksin its grasping position and the masterand toolhalves secure with one another.

A holding system includes a force control module configured to generate a force signal to cause a holding device to perform at least one of a hold stroke and a release stroke. The hold stroke includes transitioning a gripping element of the holding device to a first position to grip an object. The release stroke includes transitioning the gripping element to a second position to release the object. The holding device is non-backdrivable. A stall detection module is configured to (i) monitor a sensor signal received from a sensor of an electric motor assembly of the holding device and (ii) detect a first stall condition of an electric motor based on the sensor signal. A shut off module is configured to shut off current to the electric motor based on the detection of the first stall condition during or at an end of the release stroke.

Electric motor based holding control systems and methods

A suction cup assembly has a housing with an actuator in the housing. A flexible cup is coupled with the housing. The actuator movement causes the flexible cup to move between at least two positions. In a first position, the flexible cup moves into an increased volume position. In a second position, the flexible cup moves into at least a neutral volume position. In the increased volume position, the flexible cup seals with a surface. In the neutral volume position, the flexible cup releases from the surface.

An electric cylinder has a cylinder housing and a clamping assembly in the cylinder housing. An electric motor assembly is coupled with the clamping assembly to drive the clamping assembly between a first and second position. The electric motor assembly has an electric motor with a rotary output. The clamping assembly has a drive pulley assembly coupled with the rotary output. A lead screw is rotatably coupled with the drive pulley for axial movement. The lead screw moves between the first and second positions. A compliance coupling is positioned between the lead screw and the drive pulley. The compliance coupling is axially movable in the pulley assembly for absorbing shock when the piston assembly encounters a stop.

Electric cylinder

An electrical gripper has a housing and a solenoid plunger. A pair of jaws are movably mounted with the housing. The jaws are movable towards and away from each other. The jaws are coupled with the solenoid plunger to provide movement to the jaws. A first mechanism is associated with the solenoid plunger to lock the solenoid plunger in a first position when power is terminated to the solenoid plunger. A second mechanism is associated with the solenoid plunger to lock the solenoid plunger in a second position when power is terminated to the solenoid plunger. Thus, the jaws are actively locked in an open or close position when power is terminated to the solenoid plunger.

Solenoid gripper

An electric gripper has a housing with a motor. A gearhead is coupled with the motor. A controller is electrically coupled with the motor to control the gripper via the motor. A compliance device is coupled with the motor. The compliance device absorbs impact energy created by the device. A drive mechanism is coupled with the compliance device and with a jaw movable on the housing. Fingers are coupled with the jaw that opens and closes to grip a part.

Electric gripper drive with a torsional compliance device

A gripper has a frame with a plurality of guide rods secured to the frame. At least one jaw is slidably secured with the plurality of guide rods. The at least one jaw includes a housing surrounding a portion of at least one of the guide rods. A locking device is positioned in the jaw housing. The locking device is adjacent the at least one guide rod. The locking device removably applies a force onto the at least one guide rod. The locking device locks the jaw in position when the force is applied and enables the jaw to slide on the guide rods when the force is removed.
