摘要： An improved apparatus and methods for recovering abrasive from an abrasive-laden fluid are shown and described. An abrasive-laden fluid handling device is coupled to a catcher tank to collect abrasive-laden fluid and transport it to a hydro-classifier. Wet recovered abrasive is discharged from the hydro-classifier and transferred to a de-watering device. The de-watering device removes water from the abrasive by decanting fluid and via use of an air eduction system. De-watered abrasive is then ejected from the de-watering device to a dryer unit, to be further dried and processed for reuse.

摘要： An apparatus for generating and manipulating a high-pressure fluid jet includes an assembly coupled to a motion assembly that imparts motion to the assembly along one or more axes. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having an axis of rotation. The two axes of rotation of the two motors can be perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion. The high-pressure fluid assembly incorporates a swivel that can rotate about two axes which may be parallel to the two motors' axes of rotation, allowing the high-pressure tubing contained therein to follow the motion imparted by the gimbal wrist of the motion assembly.

摘要： This invention relates to apparatus and methods for z-axis control and collision detection and recovery for waterjet and abrasive-jet cutting systems. In one embodiment, an apparatus includes a linear rail, a slide member coupleable to a cutting head and slideably coupled to the linear rail, at least one actuator having a first end coupled to the slide member and a second end fixed with respect to the linear rail, a position sensor, and a controller. The actuator provides an adjustable support force that supports the weight of the cutting head, allowing the cutting head to be controllably positioned at a desired height above the workpiece. The actuator may include a pneumatic cylinder, or alternately, a linear motor. In another aspect, an apparatus includes a first mount member coupleable to a controllably positionable mounting surface of the waterjet cutting system, a second mount member coupleable to the cutting head and disengageably coupled to the first mount member, and a sensing circuit having a plurality of first conductive elements disposed on the first mount member and a plurality of second conductive elements disposed on the second mount member. In the event of a collision between the cutting head and an obstruction, the second mount member disengages from the first mount member to prevent breakage of the cutting head. Following the collision, the second mount member is quickly and easily re-engaged with the first mount member without time-consuming re-calibration. In one embodiment, re-engagement of the second end first mount members is automatically performed by a biasing member.
