Description
Technical field
The utility model relates to a kind of flaring tool of thin-wall metal pipe, particularly a kind of electronic mouth expander.
Background technology
As everyone knows, on the machinery equipment of industries such as refrigeration, power, processing, many interconnective thin-wall metal pipes are arranged all, when pipe connects, often need enlarging is carried out in one of interconnective two terminations, realize that in the sleeve mode simple assembling connects by enlarging; Because it is hard a lot of that relative plastics of thin-wall metal pipe or rubber tube are wanted, can not utilize its elasticity enlarging, need enlarging device by the thin-wall metal pipe special use, though and existing enlarging device operating efficiency is higher, but also exist following weak point: the one, during the pipe enlarging, there is not the automatic clutch governor motion, can only process horn mouth by rule of thumb, not of uniform size, the became uneven of horn mouth, the crudy instability; The 2nd, operation inconvenience during manual mouth expander enlarging, handle can only same direction rotation, and required torsion is bigger, and labour intensity is big, wastes time and energy; Though electronic mouth expander is laborsaving, complex structure, volume are big and heavy, are not easy to outdoor processing and carry.For this reason, many manufacturers and knowledgeable people develop and study, but do not have ideal method to solve the problem of above-mentioned existence so far as yet.
Summary of the invention
For overcoming existing mouth expander above shortcomings, problem to be solved in the utility model provide a kind of compact conformation reasonable, simple to operate laborsaving, use charged electric mouth expander easy to carry.
The technical scheme that its technical problem that solves the utility model adopts, it comprises housing, battery, two-way switch, motor, reducing gear, holder, thread bush, splined shaft, conical indenter, described holder is fixedly installed on the housing, thread bush is by being threaded on the holder, the splined shaft that is arranged with compression spring is arranged on holder and the thread bush, conical indenter is rotating to be arranged on the end face of splined shaft and the axle center of departing from splined shaft, the input of splined shaft cooperates with reducing gear, and the outside of thread bush is provided with automatic clutch mechanism.
Further preferred version of the present utility model, described automatic clutch mechanism comprises clutch cover, clutch discs, on-of pin, clutch spring, thread bush and clutch discs are provided with the clutch slot of mutual correspondence, on-of pin and clutch spring are arranged on this clutch slot, the other end of clutch spring withstands on the clutch cover, clutch cover and clutch discs by the flexible fastening finger setting on splined shaft.
Further preferred version of the present utility model, described reducing gear comprise motor gear, reduction gearing, spline gear and spline gear axle sleeve, spline gear and spline gear axle sleeve close-fitting, and motor output gear, reduction gearing and spline gear mesh successively.
Further preferred version of the present utility model, described thread bush is provided with the clutch plane bearing, and the one side of clutch plane bearing cooperates with holder, and another side cooperates with clutch cover.
Further preferred version of the present utility model is provided with the splined shaft spring between described automatic clutch mechanism and the spline gear axle sleeve.
Further preferred version of the present utility model, the interface of described holder are provided with hoodle and prevent the elastic ring that hoodle is deviate from.
After adopting said structure, provide power by battery, in pipe enlarging process, the motor via reducer structure drives the splined shaft rotation, also drive the automatic clutch mechanism rotation simultaneously, automatic clutch mechanism drives thread bush screwfeed and compression pressure spring, and compression spring pushing tow splined shaft makes conical indenter to being produced extruding by the pipe of enlarging, splined shaft is moved axially, begin pipe is carried out enlarging; After the certain distance of thread bush screwfeed, on-of pin separates in the clutch slot of thread bush gradually, and the on-of pin disengaging combined with the clutch slot of thread bush after enlarging put in place, and automatic clutch mechanism continues to rotate with splined shaft, thread bush stops screwfeed, thereby finishes the enlarging of pipe; Because auto-feed, separation automatically, the pressure during enlarging remains in certain scope substantially, so pipe is stressed evenly, speed is fast, the enlarging quality is good; Be provided with, rotate freely because conical indenter is eccentric, so conical indenter and pipe contact-making surface are little, required moment of torsion is also just little, and enlarging is laborsaving; Have simple and reasonable, pipe enlarging steady quality, rapid operation, advantage such as easy to carry.
