摘要： A split sleeve (96) is seated in a fastener hole (10) in the web (8) of a rail section (2). The tapered portion (26) of a mandrel (20) is firmly seated in the hole (10) inside the sleeve (96). A puller mechanism jaw (40) and a nosecap (78) are moved downwardly over the projecting rear end portion of the mandrel (20) to position the rear end portion in aligned U-shaped slots (50, 84) in the jaw (40) and nosecap (78). During the downward movement, guide surfaces (72) carried by the jaw (40) guide a chamfer (32) on the mandrel (20) into seating engagement with a tapered surface (56) on the jaw (40). The guide surfaces (72) may be formed by cylindrical pins (70) received into angled openings (58) in the jaw body. The front surface (88) of the nosecap (78) securely abuts the Web (8). With the mandrel ( 20) seated and the nosecap (78) abutting, the jaw (40) is moved rearwardly to pull the mandrel (20) through the hole (10) and cold expand the hole (10).

摘要： An internally lubricated, longitudinally split sleeve is positioned on a small diameter portion a mandrel having a rear end connected to a piston with a puller tool. The rear end of the split sleeve is flared and is against the front end of a tubular sleeve stop which immediately surrounds the mandrel. The puller tool includes a tubular sleeve holder which surrounds the sleeve stop. A forward main portion of the sleeve holder is separated by a pair of longitudinal slots into a pair of elongated fingers. The forward ends of the fingers define a sleeve and mandrel receiving end opening and jaws radially outwardly bounding the opening. The mandrel and sleeve holder are both extended and then the puller tool is moved into alignment with a sleeve and is moved endwise to push the mandrel through the sleeve until the flared end of the sleeve is against the sleeve stop. Then the sleeve holder is retracted. Next, the mandrel and sleeve are inserted into a hole in a workpiece and the tool is moved forwardly until the front ends of the jaws are against the workpiece. Then, the puller tool is operated to retract the mandrel through the sleeve and into the sleeve stop. Retraction of the mandrel moves first an increasing diameter portion of the mandrel and then a maximum diameter portion of the mandrel through the sleeve which radially expands the sleeve and cold expands the material immediately surrounding the hole in the workpiece. After the mandrel is retracted into the sleeve stop, the puller tool is moved away from the workpiece. The jaws of the sleeve holder engage and retain the sleeve so that the sleeve is pulled out from the hole in the workpiece.

摘要翻译： 内部润滑的纵向分开的套筒定位在小直径部分上，心轴具有通过拉拔工具连接到活塞的后端。 开口套筒的后端是喇叭形的，并且紧靠着立即围绕心轴的管状套筒止动件的前端。 牵引工具包括围绕套筒止动件的管状套筒保持件。 套筒保持架的前部主要部分由一对纵向狭缝分隔成一对伸长的指状物。 指状物的前端限定了套筒和心轴接收端部开口并且径向向外限定开口。 心轴和套筒保持架都伸出，然后将牵引工具移动成与套筒对准，并使其向后移动以将心轴推过套筒，直到套筒的喇叭形端部抵靠套筒止动件。 然后套筒保持架缩回。 接下来，心轴和套筒插入到工件中的孔中，并且工具向前移动，直到夹爪的前端抵靠工件。 然后，牵引工具被操作以使心轴通过套筒缩回到套筒止动件中。 心轴的回缩首先移动心轴的增加的直径部分，然后通过套筒的心轴的最大直径部分径向扩张套筒，并且冷却使紧邻工件的孔的材料膨胀。 在心轴缩回到套筒止动器之后，拉出工具从工件移开。 套筒保持器的夹爪接合并保持套筒，使得套筒从工件中的孔中拉出。

摘要： The present invention provides a method of installing a grommet within an opening in a wall of composite material. An opening (10) is formed in a wall of composite material (12). A countersink (20) is formed at one end of the opening (10). A grommet (22) is placed into the opening (10). A split sleeve (28) is placed on the small diameter portion (30) of a mandrel (32) which is attached to a power puller (36). The mandrel (32) with the split sleeve (28) is placed through the opening (10) and a grommet (22). The power puller (36) is then operated to pull the mandrel (32) back through the opening (10) and the grommet (22) thereby expanding the split sleeve (28) which in turn provides for the radial expansion of the grommet (22). During the radial expansion of the grommet (22), ends of fibers (16) are forced into the surface of the grommet (24 ). After the mandrel (32) has been pulled all the way through the split sleeve (28) both it and the split sleeve (28) are removed from the grommet (22). This leaves the grommet (22) securely fastened within the opening (10) in the composite wall (12).

摘要： A circular opening (54) is formed in a wall (12). A tubular shank (42) of a nut mounting unit (40) is inserted into the opening (54). The unit (40) is moved endwise to place a nut cage base (46) against the wall (12). A split sleeve (82) is installed on a small diameter portion (90) of a mandrel (M). The mandrel (M) and sleeve (82) are inserted into the tubular shank (42) from the side of the wall (12) opposite the nut cage (44). The mandrel (M) is then retracted to successfully move increasing and maximum diameter portions (90, 92) of the mandrel (M) through the split sleeve (82). The mandrel portions (92, 94) exert a radially outwardly expanding force on the split sleeve (82). The split sleeve (82) in turn imposes a radially outwardly expanding force on the tubular shank (42). This causes a plastic deformation of the tubular shank (42), creating a tight interference fit between the tubular shake (42) and the sidewall of the opening (54). In this manner, the unit (40) is firmly secured to the wall (12). Next, a nut (20) is inserted into the nut cage (44), between end stops (56, 58). A retainer spring (68) is placed over the base (24) of the nut (20), and is compressed an amount sufficient to move side portions (64, 66) together enough that they will fit between cage sidewalls (48, 50). Then, the squeezing force on the retainer spring (68) is released, allowing side portions (64, 66) to move outwardly into openings (60, 62) in the sidewalls (48, 50). In this position the sidewalls (48, 50) restrain sideways movement of the nut. The end stops (56, 58) restrain endwise movement of the nut (20). The inner spring (68) prevents movement of the nut (20) out from the nut cage (44).

摘要： A split sleeve (S) is deposited into a sleeve loader (24, 24'), with a lower end of the sleeve (S) on a sleeve support surface (154). A mandrel (M) carried by a puller tool (10, 10') is inserted into the sleeve loader (24, 24'), and through the sleeve (S), to position the sleeve (S) on a small diameter portion (50) of the mandrel (M), and an end portion of the sleeve (S) within a nosepiece (12), against a sleeve end contacting surface (66). The tool (10, 10') is moved away from the sleeve loader (24, 24') to pull the mandrel (M) out from the sleeve loader (24, 24'). Then the mandrel (M) is inserted into an opening (16) in a workpiece (14). The tool (10, 10') is moved endwise to place the sleeve (S) within the opening (16) and a workpiece contacting end surface of the nosepiece (12) into contact with the workpiece (14). The tool (10, 10' ) is then operated to retract the mandrel (M). This moves first an increasing diameter portion (52) and then a maximum diameter portion (54) of the mandrel (M) axially through the sleeve (S). In response, the sleeve (S) is expanded radially to compress the material immediately surrounding the opening. Grip surfaces (158) on end portions of nosepiece fingers (78) grip the sleeve (S). Following retraction, the tool (10, 10') is moved away from the workpiece (14) and the sleeve (S) is pulled out from the opening (16).

摘要： A circular opening (48) is formed in a structural wall (12). A tubular shank (28) of a nut mounting grommet (26) is inserted into the opening (48). The grommet (26) is moved endwise to place a shoulder surface (34) on the base of a nut mounting cup (30) against the wall (12). A split sleeve (54) is installed on a small diameter portion (62) of a mandrel (52) and the mandrel and sleeve (52, 54) are inserted into the tubular shank (28) from the side of the wall (12) opposite the nut receiving cup (30). The mandrel (52) is then retracted to successively move increasing and maximum diameter portions (64, 66) of the mandrel (52) through the split sleeve (54). The mandrel portions (64, 66) exert a radially outwardly expanding force on the split sleeve (54). The split sleeve (54) in turn imposes a radially outwardly expanding force on the tubular shank ( 28). This causes a plastic deformation of the tubular shank (28), creating a tight interference fit between the tubular shank (28) and the sidewall of the opening (48). In this manner, the grommet (26) is firmly secured to the wall (12). Next, a nut (24) is inserted into the cup (30) with its threaded central opening (18) in alignment with the passageway through the tubular shank (28). The sidewall of the cup (30) is deformed, to place portions of a lip (46) endwise of the nut (20), in the path of removal of the nut (20) from the cup (30). The sidewall of the cup (30) includes wrench flats (98) outwardly bounding wrench flats (100) on the nut (20).

摘要： A tubular stem (14) at one end of a nut mount (10) is inserted into an opening (O) in a wall (W) and is expanded to connect it to the wall (W). An annular collar or space (16) contacts the wall (W) where it immediately surrounds the opening (O). A clip-on nut (12) is clipped onto a nut receptor (18) that is endwise outwardly of the collar (16). A pushing movement on the clip-on nut (12) moves catch tabs (54, 56) past diametrically opposite edge portions (30, 32) of the nut receptor (18), placing them into positions below the edge portions (30, 32) of the nut receptor (18). When the catches (54, 56) are so positioned, they hold the clip-on nut (12) on the nut receptor (18). The clip-on nut (12) may be a sealed nut. If so, catch tabs (54, 56) are positioned so that when they engage underneath portions of the edge portions (30, 32) of the nut receptor, a seal ring at the base of the clip-on nut (12) is compressed. This compressing of the seal ring (48) causes the clip-on nut to be sealed prior to connection of a bolt to the clip-on nut (12).
