Accompanying drawing explanation
Fig. 1 is the structural representation sketch of the outer raceway machining fixture system of this utility model motor turning screw rod；
Fig. 2 is part screw rod processing technique figure.
Detailed description of the invention
The outer raceway machining fixture system of this utility model motor turning screw rod, is formed including chuck retained part 1, angular positioner 2, rotating centre device 4, tailstock center device and tailstock fine setting hydraulic system 3.Wherein
1, chuck retained part 1 is made up of standard chuck and claw.
2, angular positioner 2 by cylinder piston 2-1, locating centre 2-2, spring 2-3 and spring detent 2-4 can be swung form by trace, described can trace swing locating centre 2-2 be arranged on cylinder piston 2-1 top, its top can be plugged into is processed in the hole, location on part 7, and spring 2-3 is arranged on cylinder piston 2-1.Angular positioner 2 integral installation is on the end face of chuck retained part 1, and cylinder piston 2-1 thereon is (to be included that source of the gas 8 drives by external pneumatic parts.Can swing in the top hole, location that can be plugged into processing part 7 of locating centre 2-2 by trace, that can offset that part axial scale error brings axial crosses location.
3, rotating centre device 4 is arranged on the end face center position of chuck retained part 1, it is made up of the top 4-1 of rotation and swivel bearing 4-2 equipped with coarse positioning key 4-3, and one end endoporus spline of processing part 7 can be plugged in the coarse positioning pin 4-3 on the top 4-1 of described rotation.Rotate top 4 can rotate, cross location for what the hole, counteracting location when the middle trace of angular positioner 2 swings locating centre 2-2 insertion rotated in a circumferential direction.
4, tailstock center device 6 is connected with tailstock fine setting hydraulic system 3, and is adjusted location by tailstock fine setting hydraulic system 3.Described tailstock fine setting hydraulic system 3 is made up of Hydraulic Station and hydraulic valve bank, hydraulic valve bank is mainly by controlling the superposition reversal valve 3-1(three-position valve that tailstock is return, advanced, Median Function stops, another two commutations), and tailstock return on oil circuit increase superposition electromagnetic throttle valve 3-2(electromagnetic valve be two-position valve, wherein a function throttling is for returning at a slow speed, and another one realizes normally returning without throttling, and electrical system instruction controls the switching between two stations of electromagnetic valve) composition.Add tailstock center after man-hour processing part 7 being put into material supporting rack 5 and hold out against part, control the most again reversal valve energising commutation return (during returning superposition electromagnetic throttle valve energising throttling function enable for returning at a slow speed,) energising 0.5S after power-off reversal valve be quickly returning to middle position, tailstock center stopping action.Realize tailstock trace with this and return several millimeters, so tailstock center is top with rotation would not be motionless for part dieback, and two top processing parts of also holding up in the centre bore at screw rod two ends, would not the rotary freedom of limit feature, location would not be produced when swinging locating centre and heading into hole, part location.After completing Deng location, tailstock again commutates and holds out against processing part, and chuck retained part clamps processing part again.
Fig. 2 is part screw rod processing technique figure: two ends are top to be held out against, and location, screw rod one end angle of spot hole, to location, then processes raceway.The following (see figure 1) of operating process:
First operator will process part 7(screw rod) it is placed on material supporting rack 5, process part 7(screw rod) the coarse positioning key 4-3 that inserts in rotating centre device 4 of big terminal link groove completes coarse positioning.nullThen tailstock fine setting hydraulic system 3 controls reversal valve 3-1 commutation，Make tailstock center advance to push up and tight part (screw rod)，Control the most again reversal valve 3-1 commutation return (during returning superposition electromagnetic throttle valve 3-2 energising throttling function enable，For returning at a slow speed)，Power-off after energising 0.5S，Reversal valve 3-1 is quickly returning to middle position，Tailstock center device 6 stops mobile，Realize tailstock trace with this and return several millimeters，So tailstock center device 6 would not dieback part (screw rod) with the top 4-1 of rotation，But two top also processing part 7(screw rod) two ends centre bore in hold up part 7(screw rod)，Thus without limitation on the rotary freedom of part，At this moment angular positioner 2 is in by source of the gas after pneumatic line commutation，By spring 2-3 control can trace swing locating centre 2-2 be easier to insert part 7(screw rod) hole, location in，Wherein spring detent 2-4 swings the reset of locating centre 2-2 for trace.Controlling reversal valve 3-1 commutation after having positioned, tailstock center device 6 holds out against part 7(screw rod again), pull 3 vice card pawl 1-1 of chuck retained part 1 to complete holding action by ventilation oil cylinder 9.Finally again unclamping claw 1-1, angular positioner 2 carries out 2 location again by source of the gas switching gas, again eliminates position error.Though two top parts (screw rod) that head on inflexibly, but it is equipped with swivel bearing 4-2 owing to rotating in top 4-1, tailstock center 7 is the most rotatable, and angular positioner also will not produce crossing of circumference and position when inserting.The 3 secondary self-control claw 1-1 pulling chuck retained part 1 again by ventilation oil cylinder 9 complete holding action, Clamp blocks, and clamping terminates.
