The technique effect of design of the invention, concrete structure and generation is carried out clearly below with reference to embodiment and accompanying drawing
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/annexations, not singly refer to that component directly connects, and refer to that can be added deduct by adding according to specific implementation situation
Lack couple auxiliary to constitute more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
As illustrated in fig. 1 and 2, a kind of pipe-expanding machine, including frame, the frame includes pipe fitting feeding machanism, pipe fitting localization machine
Structure, pipe fitting expanding mechanism and pipe fitting discharging opening, the pipe fitting expanding mechanism include the first motor, the first travelling gear 1, crank 2,
Connecting rod 3, sliding seat 4, guide rail 5, drift 6, first motor drive the first travelling gear to rotate 1, one end of the crank 2
Coaxial with the first travelling gear 1, the other end is hinged with the front end of connecting rod 3, and rear end and the sliding seat 4 of the connecting rod 3 are hinged, institute
Sliding seat 4 and the sliding contact of guide rail 5 are stated, the drift 6 is fixedly connected and parallel with guide rail 5 with sliding seat 4, the pipe fitting positioning
Mechanism includes discharge frame 7, the second motor, feed device, hoistable platform 8 and compressing member 9, and the front and back ends of the discharge frame 7 are distinguished
It is connected with pipe fitting feeding machanism and pipe fitting discharging opening, the discharge frame 7 is provided with multiple positioning being adapted with pipe fitting outline
Groove 10, the feed device have two groups and respectively be located at the arranged on left and right sides of discharge frame 7, the feed device include all the time with discharge
The cross bar of frame keeping parallelism, the cross bar is provided with the support mouthful being adapted with discharge frame, and second motor drives feeding rod
Make circular motion from back to front, the compressing member 9 is connected with the bottom of hoistable platform 8, the hoistable platform 8 drives compressing member 9 to press
Tightly or away from discharge frame 7.The crank 2, connecting rod 3 and sliding seat 4 composition crank rocker sliding pair so that motor only needs output
Unidirectional power, you can realize moving in circles for drift 6.Because whole plunger mechanism is machine driving, so the row of drift 6
Journey is fixed, it is not easy to changed；Meanwhile, discharge frame 7 causes that pipe fitting can keep good suitable before it will enter enlarging station
Spacing, by cross bar by the synchronous stepping forward of multiple tubing element on discharge frame 7, is prevented effectively from positioning inaccurate so that whole enlarging
