Incorporated by reference to reference to Fig. 4 to Fig. 6, during assembling, some snap rings 10 are sheathed on to the clip 64 of holder 60 certainly away from one end of stop surface 65.The one end that is provided with stop surface 65 that is equiped with the holder 60 of snap ring 10 is pushed in the stepped hole 35 of frame 30 from the first end 32 of frame 30, and when this holder 60 is resisted against the sidewall of this stepped hole 35, can wear the first side wall of this frame 30 and be screwed together in this holder 60 and this holder 60 is fixed on to frame 30 by screw, and holder 60 parts be exposed at the outside of first end 32.Feed member 70 pushes the chute 82 of guide 80 from one end of guide 80, now, the guide rod 522 of the first cylinder 52 stretches into chute 82 and is fixed in the locating hole 73 of feed member 70 from the other end of guide 80.The guide 80 that is equiped with feed member 70 is pushed into through hole 36 completely from the second end 34 of frame 30, and wears second sidewall relative with the first side wall of this frame 30 and be screwed together in this guide 80 and this guide 80 is fixed on to frame 30 by screw.Now, on the snap ring 10 of push part 74 pushing tows of feed member 70 on the stop surface 65 that is placed in holder 60.The guide rail 412 of impeller 40 is sticked in the sliding tray 38 of the first end 32 of frame 30 slidably.Now, the part that holder 60 is exposed at frame 30 outsides is contained in the receiving space 413 of impeller 40; Holder 60 keep away a hole 62 over against the locating hole 414 of impeller 40; Snap ring 10 on holder 60 is over against the limited wall 415 of impeller 40, and holder 60 is positioned at an outermost snap ring 10 and can departs from holder 60 and be placed on the promotion face 43 of impeller 40 and be resisted against limited wall 415.Therefore, the distance between limited wall 415 and the end face of holder 60 equals the width of promotion face 43, to guarantee an only having snap ring 10 depart from and be placed in the promotion face 43 of impeller 40 from holder 60 at every turn.The pushing part 104 of yoke frame 100 is slidably mounted on the sliding tray 92 of fixture 90, and fixture 90 can be screwed the second sidewall in frame 30.Now, the push block 107 of pushing part 104 is contained in the space of the otch 44 of impeller 40 and plate body 47 formation of resetting block 42, and the first pushing tow face 108 of push block 107 is against the inclined plane 440 of impeller 40.Keeper 110 is fixed in the holddown groove 94 of fixture 90, and the location division 112 of keeper 110 is resisted against pushing part 104, and the second pushing tow face 109 of push block 107 is supported the stop surface 115 of keeper 110.First and

second cylinder

52,53 is connected to feed member 70 and yoke frame 100 by the connecting rod 121 of connecting portion 520, connector 120.

Workpiece 22 is fixed on the second side of impeller 40, and the body of rod 24 of screw 20 stretches into the locating hole 414 of impeller 40 from the second side of impeller 40, and this body of rod 24 stretch into holder 60 keep away a hole 62, to locate this screw 20.The draw-in groove 26 of screw 20 is over against the promotion face 43 of impeller 40.

Incorporated by reference to reference to Fig. 7 and Fig. 8, during use, operating the first cylinder 52 drives feed member 70 to move along the axial first end 32 to frame 30 of screw 20, to be installed in the outermost snap ring 10 of holder 60 and eject this holder 60, this snap ring 10 is resisted against limited wall 415 and the promotion face 43 of impeller 40, thereby this feed member 70 at every turn can only be by 10 pushing and pressing of a snap ring to being resisted against limited wall 415.

Incorporated by reference to reference to Fig. 9 and Figure 10, operate pushing part 104 that the second cylinder 53 drives yoke frames 100 axially moving to the first end 32 of frame 30 along screw 20.Now, the push block 107 of pushing part 104 moves in the space of the otch 44 of impeller 40 and plate body 47 formation of resetting block 42, the first pushing tow face 108 of push block 107 squeezes the inclined plane 440 of pushing tow moving parts 40, force impeller 40 to the direction motion of the second end of pushing block 41, make limited wall 415 and promotion face 43 along the radial direction of screw 20 near screw 20.So the snap ring 10 between promotion face 43 these end faces at holder 60 of promotion and limited wall 415 is sticked in the draw-in groove 26 of this screw 20.During reset, operate the second cylinder 53 and drive second end 34 of pushing parts 104 along the sliding tray 92 of fixture 90 to frame 30 to move.Now, the second pushing tow face 109 of push block 107 moves along the sliding surface 46 of the resetting block 42 of impeller 40, and this sliding surface 46 of pushing tow, thereby drive impeller 40 laterally back move and make limited wall 415 and promotion face 43 away from screw 20, to reach the object of reset.When the second pushing tow face 109 is resisted against the stop surface 115 of keeper 110, these pushing part 104 stop motions.

Take off the workpiece 22 that installs snap ring 10.Now, if need to snap ring 10 be installed on the screw 20 of next workpiece 22, only need to this next one workpiece 22 be fixed on impeller 40 and make its screw 20 stretch into the locating hole 414 of impeller 40, can start next operation cycle

Obviously, in other embodiments, this first and

second cylinder

52,53 can be also as driving elements such as punch press, cylinder or hydraulic cylinders.This feed member 70 also can be by a flexible member (such as spring etc.) pushing and pressing snap ring 10 as driving.
