The specific embodiment
Describe concrete structure of the present utility model and operating process with reference to the accompanying drawings in detail.The utility model tapping machine is an example with SB4172X2 type tapping machine tapping process, and the utility model is made up of speed change gear, self-powered platform, overload-release clutch, the manual feeder of main shaft and speed of mainshaft automatic display unit.Main transmission makes the wide bead apex 16 of driving wheel 10 drives pass to follower 14 to motion by the axle sleeve 8 that is connected on the motor shaft, thereby power is passed on the power shaft 13 after motor 2 startings, and this part is a buncher.Specification according to machining screw is required with different materials, the height of the speed of mainshaft, rotate by turbine 4, driving turbine wheel shaft 5 rotates, because the rotation direction difference then screw mandrel of turbine wheel shaft 5 right-hand members drives slide block 6 move left and right, the lever 12 that it stirs the band shift fork promotes initiatively to adjust wheel 15 move left and right, and this moment, passive adjustment wheel 9 drags that overcome pressure spring 7 were equilibrated on a certain drive diameter of driving wheel wide bead apex 16, passed to power shaft 13 thereby can obtain the different rotating speed of height.Power shaft in gearbox by just change gear be driving gear 17 and counter-rotating driving gear 27 respectively with electromagnetic clutch 23 and electromagnetic clutch 25 moving plates on the passive gear 22 that just changeing, counter-rotating driven gear 26 has been formed two prescriptions on the contrary, and the counter-rotating rotating speed is 1.6 times the gear train of speed of just walking around, when just changeing tapping and counter-rotating withdrawing, pass through electromagnetic clutch 28 respectively, bevel pinion 29, bevel gear wheel 32, spline housing 31 is passed to main shaft 30, finished main transmission, its purpose of walking around the speed height anyway is: just changeing the durability that low speed helps guaranteeing the tapping quality and improves cutter; Counter-rotating helps boosting productivity at a high speed.Just changeing gear 17 is to be rotatably assorted by chain wheel 59 to be contained on the diameter of axle of power shaft 13, and the overload-release clutch that steel ball 60, pressure cartridge box 61, steel ball seat 62, feather key 63 and adjustment dish 64 are formed is housed on the right-hand member power shaft diameter of axle of chain wheel.The transmission of just changeing gear 17 is to finish by the adhesion between overload-release clutch upper chain wheel and the steel ball, when main shaft 30 overloads, main shaft, big bevel pinion all do not change, but the drag that overcomes spring 61 by steel ball is rolled on the inclined-plane of chain wheel 59, steel ball has been freed the resistance of chain wheel, chain wheel and just changeing gear and all do not rotating then, thereby the safety when having guaranteed overload.Axis feeding and recoil movement are seen Fig. 1 during tapping, Fig. 2 and Fig. 3, the screw tap of main shaft 30 and its lower end of dress is in topmost when starting working, move handle 53 earlier, it drives rack sleeve 33 fast to lower slider by the tooth bar 33a on feed gear on the Handle axis 55 35 and the rack sleeve 33, when the nearly workpiece of screw tap smear metal tapered joint draw buckle after, just release handle, then under the guiding of screw tap pitch, carry out the self-acting feed tapping, when attacking to the depth of thread that requires, anti-converting iron 49 is stirred travel switch 56 commutations immediately at this moment, then left electromagnetic clutch 23 outage idle running, and right electromagnetic clutch 25 connects electric adhesive, withdrawing driving gear 27 drives withdrawing driven gears 26 at this moment, electromagnetic clutch 28, drive bevel pinion 29, bevel gear wheel 32, make main shaft 30 counter-rotatings by spline housing 31 again, under the guiding of screw tap pitch, the main shaft limit is rotated the edge and upwards slip of spline housing, be separated from the upper surface of workpiece screw thread when screw tap after, just under the clockwork spring effect in going barrel 50, main shaft 30 rises along spline housing fast, in the time will rising to topmost, just change buting iron 48 and stirring travel switch 56 commutations, main shaft 30 recovers just changeing to finish a working cycles.The automatic demonstration of the speed of mainshaft is to realize (seeing Fig. 1, Fig. 2 and Fig. 5) like this, lathe is in operation process, a magnetic induction sensor 18 is equipped with in the back of fault wall 19, a fault wall 19 between the magnetic that the rear end of electromagnetic clutch 28 is being adorned and it rotates synchronously, it links the signal that changes by lead and micro computer rotational speed meters 54, then micro computer rotational speed meters 54 is presented at the actual speed of main shaft 30 on the dial plate automatically.
Self-powered platform device (see figure 1) is made up of workbench 36, jacking sleeve 37, axle sleeve 38, elevating screw 39, locking pin 40, turbine worm (41,42) mechanism and lifting handwheel 47.Unclamp locking pin 40, lifting handwheel 47, rotate drive elevating screw 39 and rotate by scroll bar 42, turbine 41, drive jacking sleeve 37 makes workbench 36 rise under the feather key effect thereupon or descends, to satisfy the different requirement of workpiece height, after screwing locking pin 40 then, can carry out the installation and the tapping work of workpiece.
