摘要： A fluid jet system (200) includes an upstream high-pressure body (202) having a high-pressure bore (308) axially positioned, a retaining nut (204) configured to couple to the upstream high-pressure body (202), and an orifice mount assembly (206). The retaining nut (204) includes a mounting chamber (216) configured to laterally receive the orifice mount assembly (206) without application of a torque while the retaining nut (204) is coupled to the upstream high-pressure body (202) and the system is at ambient pressure. A face seal (316) may be mounted in either a downstream portion of the high-pressure bore (308) or the orifice mount assembly (206) to provide a high-pressure seal while the system is pressurized.

摘要： An improved apparatus for generating a high-pressure fluid jet includes an orifice mount (11) having a frusto-conical surface (12) that engages a frusto-conical wall in a cutting head (22), the geometry of the orifice mount (11) and cutting head (22) being selected to increase the stability of the mount and reduce deflection of the mount adjacent a jewel orifice (20), when subjected to pressure. Alignment of a nozzle body (37) and the cutting head (22) is improved by providing pilot diameters both upstream and downstream of threads on the nozzle body (37) and bore (23) of the cutting head, respectively. Accurate placement of a mixing tube (49) in a cutting head is achieved by rigidly fixing a collar (52) to an outer surface of the mixing tube (49), the collar engaging a shoulder (34) and bore of the cutting head downstream of a mixing chamber (33), to precisely locate the mixing chamber (33) axially and radially.

摘要： A seal assembly (20) having a backup ring (26) through which a piston reciprocates. There is a seal sleeve (58) made of a non-abrading, extrusion resistant material that surrounds the piston at a location forwardly of the backup ring (26). The backup ring (26) has an opening (42) to receive the piston (14), and the opening (42) is formed to define a radially and rearwardly expanding gap (52) between the piston (14) and backup ring (26) to receive and discharge any seal material which may extrude into the gap. There is a positioning flange (36) integral with the backup ring (26) that surrounds the seal sleeve (58) to press the seal sleeve (58) into engagement with the piston (14), and there is an outer seal portion (88) to form a seal between the positioning flange (or the outer portion of the backup ring) and the cylinder.

摘要： An abrasivejet system for cutting brittle materials is disclosed. One feature of the disclosed system is a jet-producing nozzle assembly (10) which includes means for inducing turbulence in the jet-forming liquid during the period in which the jet initially impacts on the brittle material so that impact stress on the material is reduced. A second disclosed feature is a supplementary suction device (12), preferable in the form of a second nozzle dimensioned for maximum suction, which maintains a generally constant feed rate of abrasive into the cutting nozzle assembly during the turbulence-inducing phase of operation.

摘要： An apparatus (10) for generating and manipulating a high-pressure fluid jet includes an end effector assembly (14) coupled to a manipulator that imparts motion to the end effector along one or more axes. The end effector assembly (14) includes a cutting head (15) coupled to a source of high-pressure fluid and to a source of abrasive, to generate a high-pressure abrasive fluid jet. A motion assembly (20) is coupled to the cutting head via a clamp (21) positioned around the cutting head. A nozzle body assembly (30) is removably coupled to the cutting head assembly (15) upstream of the orifice. The nozzle body assembly (30) may be separated from the cutting head assembly (15) to allow access to the orifice, without removing the cutting head assembly (15) from the clamp (21). The clamp (21) has a quick release mechanism (81), allowing an operator to open the clamp by hand to allow access to the cutting head, and an alignment member is provided on an inner surface of the clamp to accurately locate the cutting head in the clamp. The motion assembly (20) includes two motors (40,41) coupled together to form a gimbal wrist, each motor having a horizontal axis of rotation. The two axes of rotation (82,83) are perpendicular to each other, but are not aligned with the manipulator's axes of motion. Spray from the abrasive fluid jet is contained by a shield (37) provided directly in an end region of the cutting head assembly (15).

摘要： An abrasivejet nozzle assembly is disclosed which is particularly suitable for drilling small diameter holes in a workpiece. Such assemblies include a mixing region (42) wherein abrasive particles are entrained into a high velocity waterjet formed as high pressure water is forced through a jet-forming orifice (18). Among the unique features of the nozzle assembly are an inwardly tapered abrasive path (46a) just upstream of the mixing region, flushing conduits (48,59) immediately upstream and downstream of the mixing region, and a venting passageway (50) upstream of the mixing region which prevents the backflow of abrasive dust towards the jet-forming orifice.
