Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in detail.
It is the deficiency for overcoming prior art that the purpose of the present invention is, and provides spiral shell in a kind of disposable rapid processing of energy
Stricture of vagina, the internal thread tapping machine of efficiency high.
As shown in figure 1, motor 12 drives V belt translation 1 to move, the big belt wheel axle of V belt translation 1 by electromagnetic clutch 2 with it is convex
The connection of 3 axles is taken turns, cam 3 is rotatably hinged in frame 13, and the afterbody of sector gear 4 is flexibly connected with cam 3, constitutes higher pair,
The middle part of sector gear 4 is rotatably hinged in frame 13, when cam 3 rotates, can drive sector gear 4 with sector gear 4
The tooth of oscillating motion, the tooth of the head gear of sector gear 4 and the tooth bar 5 with ball nut is done for axle with the hinged place of frame 13 in portion
Engagement, when 4 clockwise oscillation of sector gear, drives the tooth bar 5 with ball nut to move down, band by the engagement of head gear
The tooth bar 5 of ball nut constitutes rolling screw pair with ball-screw 6, and ball-screw 6 is fixedly connected with little gear 7, little gear 7 and
Gear wheel 8 is engaged, and screw rod 9 is arranged on the center of gear wheel 8 by the axle sleeve of gear wheel 8, and gear wheel 8 rotates, and screw rod 9 also rotates,
Screw rod 9 can slide in the axle sleeve of gear wheel 8.The slip screw pair that screw rod 9 is constituted with nut 11 in frame 13.Screw tap 10 is pacified
The lower end of screw rod 9 is mounted in, the pitch of its plug tap 10 is identical with the pitch of screw rod 9.
The present invention operation principle be：During work, motor 12 drives the rotary motion of V belt translation 1, the big belt wheel axle of V belt translation 1
Coupled with the axle of cam 3 by electromagnetic clutch 2, in the rise motion stage of cam 3, make the clockwise oscillation of sector gear 4, drive band
The tooth bar 5 of ball nut is moved downward.During the tooth bar 5 with ball nut is moved downward, the rotation fortune of ball-screw 6
It is dynamic, so as to little gear 7 also rotates, drive gear wheel 8 to rotate by gear engagement, screw rod 9 also rotates, while screw rod 9 is in frame
Relative frame is moved downward in the presence of 13 nut 11, the screw tap 10 being arranged on screw rod 9 is moved downward and is rotated, i.e., in fact
The tapping of female thread is showed.In the drawback movement stage of cam 3, the counter-clockwise swing of sector gear 4, tooth bar 5 is moved upwards, ball
The counter rotational movement of leading screw 6, so as to little gear 7 is also reversely rotated, drives gear wheel 8 to reversely rotate, screw rod 9 by gear engagement
Also reversely rotate and relative frame is moved upwards, screw tap 10 is also moved upwards and rotated backward, and exits tapping, electromagnetic clutch 2
Separate, so that the stop motion of cam 3, completes a tapping.
Fig. 2 is the electric machine control system schematic diagram for controlling whole equipment, and its on-off control is as shown in figure 3, work as circuit breaker Q F
After closure, motor M (i.e. motor 12 in Fig. 1) activate switch SB2 is pressed, catalyst KM2 coil electricities, catalyst KM2's is dynamic
Conjunction contact is closed, and forms self-locking, and motor M is powered, and is started working, when motor start switch SB2 unclamps, due to catalyst
KM2 has formed self-locking, so motor is constantly in energization working condition.When press tapping start switch SB3 when, catalyst KM1,
The coil electricity of energization delay relay KT, the moving together contact closure of catalyst KM1, electromagnetic clutch YC (i.e. electromagnetism in Fig. 1
Clutch 2) work, because now travel switch ST is in closure state, catalyst KM1 forms self-locking, unclamps tapping and starts out
When closing SB3, electromagnetic clutch YC is constantly in "on" position.After work a period of time, the time delay of energization delay relay KT is closed
The break contact of conjunction disconnects.When machine operation disconnects travel switch ST, the coil losing electricity of catalyst KM1, catalyst KM1's touches
Point disconnects, and electromagnetic clutch YC quits work, and completes a tapping process.When press again tapping start switch SB3 when, connect
The coil electricity of tentaculum KM1, the moving together contact closure of catalyst KM1, electromagnetic clutch YC is powered and starts working, due to now going
Cheng Kaiguan is still within off-state, and catalyst KM1 can not form self-locking.But because the time delay of energization delay relay KT is closed
The break contact of conjunction is in closure state, so unclamp tapping to start to switch SB3, electromagnetic clutch YC is still switched on work.
After electromagnetic clutch YC operation a period of times, travel switch ST closures, catalyst KM1 forms self-locking.Afterwards, prolong due to being powered
When coil KT time-lag action, the break contact of the timing closing of energization delay relay KT disconnects, due to catalyst KM1 from
Lock is acted on, and electromagnetic clutch YC is still switched on work.When travel switch ST is again off, electromagnetic clutch YC stops dead electricity
Only work, complete a tapping process.When shutdown switch SB1 is pressed, whole control circuit dead electricity, motor M dead electricity stops work
Make.
