Description
Technical field
The present invention relates to the process equipment field of gear, and in particular to a kind of herringbone bear processing unit (plant).
Background technology
Helical gear has to the cross force on axle, to eliminate this power, a gear is made the opposite helical teeth of symmetry direction
Take turns to eliminate this power, it appears that as individual herringbone, referred to as herringbone bear.Herringbone bear has that bearing capacity is high, stable drive
The advantages of small with axial load, it is widely used in the transmission system of heavy-duty machinery.
After shaping is made, generally there is more burr in surface to herringbone bear, in order to improve the quality of production of gear, need
Deburred is carried out to herringbone bear.The deburred mode of existing herringbone bear, is usually manually scrubbed with hairbrush.Manually
Not only processing efficiency is low for scrub, and because the tooth of herringbone bear is in " people " font, teeth groove is also in " people " word arrangement, its angle
Cleaning dead band is easily formed, artificial scrub is difficult to complete the deburred to these positions, reduces the crudy of herringbone bear.
The content of the invention
The invention is intended to provide herringbone bear processing unit (plant), making an overall screening for burr is carried out with the teeth groove to herringbone bear,
Improve the crudy of gear.
To reach above-mentioned purpose, basic technology scheme of the invention is as follows：Herringbone bear processing unit (plant), including frame, machine
Frame is provided with the first column and the second column, and the first rotary shaft is rotatably connected on the first column, and connection is rotated on the second column
There is the second rotary shaft, the second rotary shaft is connected with motor, and the second rotary shaft is provided with machining position, and the second rotary shaft is vertical away from second
One end of post is removably connected with fixed block, and clear material gear is rotatably connected in the first rotary shaft, and the inside of clear material gear is provided with
Storage cavity, is provided with the first tracheae in storage cavity, the first tracheae is provided with small opening, and several second tracheaes are communicated with the first tracheae,
Through hole is equipped with the tooth of clear material gear, the second tracheae connects one to one with through hole respectively away from one end of the first tracheae, leads to
Piston is equipped with hole, back-moving spring is connected between piston and through hole, piston coordinates with corresponding second tracheae gap respectively,
Piston both sides are equipped with scraping blade, and scraping blade is provided with gas blow pipe, and gas blow pipe is connected with corresponding second tracheae, set on gas blow pipe respectively
There is curly steel wire, gas hole is additionally provided with gas blow pipe.
The principle of this programme is：During practical application, the gas blow pipe on scraping blade in unaerated, in the curling action power of steel wire
The lower agglomerating shape of curling, scraping blade also follows gas blow pipe to be curled into bulk；When being inflated in gas blow pipe, in the supporting role of gas
Under, gas blow pipe is overcome the crimp force of steel wire and extends and stretch, and drives scraping blade extension to stretch.During work, it would be desirable to carry out
The herringbone bear of burr treatment is arranged in the machining position of the second rotary shaft and is fixed, mounted herringbone bear and clearly material tooth
Wheel intermeshes.When being engaged with herringbone bear, herringbone bear promotes the work on the tooth that clear material gear is engaged to clear material gear
Plug is slided in the second tracheae in storage cavity, and back-moving spring is stretched with, and fraction is pushed the air blowing to scraping blade
Guan Zhong, gas blow pipe is able to inflate and gradually stretch, and scraping blade follows gas blow pipe to stretch, so as in the teeth groove of corresponding herringbone bear
Slide, under the burr in teeth groove is shoveled, while teeth groove is scraped, so as to clear up the burr in teeth groove.And
When scraping blade is moved in teeth groove, teeth groove is oriented to its direction of motion, so that scraping blade is able to scrape all corners of teeth groove,
And realization makes an overall screening to burr in teeth groove.
During the woollen that scrapes of part is pushed away herringbone bear by scraping blade, and part woollen is appointed and so remains in teeth groove.Clear material gear
Continue to rotate, the site of engagement of clear material gear starts away from herringbone bear.Piston loses the extruding of herringbone bear, and in reset bullet
Return is displaced outwardly under the stretching of spring, so that the second tracheae forms negative pressure to gas blow pipe air-breathing in gas blow pipe, so that by blowing
The woollen that gas hole on tracheae will be remained in teeth groove is attracted in gas blow pipe.Into gas blow pipe woollen under airflow function quilt
It is attracted to the first tracheal strips, and by the small opening on the first tracheae into being stored in storage cavity.Gas blow pipe loses sky simultaneously
The supporting role of gas, drives scraping blade to follow steel wire to crimp again, and during curling, scraping blade slide in atmosphere and by portion
The woollen that falls within air of dispersion pushes to gas hole, and is collected in pushing to storage cavity by gas hole, in order to woollen
Focus on.
The beneficial effect of this programme：When the present invention is engaged by clear material gear with herringbone bear, piston is promoted in the second gas
Slided in pipe, and the scraping blade of curling is extended in teeth groove and is scraped to teeth groove, so as to realize to the burr in teeth groove
Cleaning, during extension of the teeth groove to scraping blade be oriented to, scraping blade is streaked all corners of teeth groove, so as to realize to tooth
Making an overall screening for groove, lifts the crudy of gear.Meanwhile, by the rotation of clear material gear, make piston self-return, in storing
Negative pressure is formed in chamber, and is drawn in storage cavity in the woollen that will be remained in the teeth groove of herringbone bear and is stored, be easy to woollen
Focus on.
Preferably, improved as one kind, drainage conduit is rotatably connected on clear material gear, be provided with same with drainage conduit in drainage conduit
Axial screw bar, screw rod is fixedly connected with the cavity wall of storage cavity.During clear material pinion rotation, the spiral shell for being secured to connection will be driven
Swing arm is rotated.Woollen into storage cavity is expelled in drainage conduit by storage cavity, under the turning effort of screw rod, on screw rod
Helicla flute by the other end from woollen to drainage conduit push, so as to realize the automatic discharge of storage cavity, prevent the hair in storage cavity
Stockpile product excessively blocks storage cavity, artificial operation is reduced, to lift processing efficiency.
Preferably, improved as one kind, drainage conduit lower section is provided with collection box.By drainage conduit discharge woollen it is direct under drop down onto
It is collected automatically in collection box, is easy to the centralized recovery of woollen to process.
Preferably, improved as one kind, magnet is provided with collection box.Magnet makes woollen be able to drop by magneticaction
In collection box, prevent woollen to be scattered in outside collection box, and destroy processing environment.
Preferably, improved as one kind, collection box lower end is provided with roller.After collection box contains woollen, weight penalty, and it is difficult
To carry, by setting roller, collection box is set flexibly to be moved, consequently facilitating the carrying of collection box.
Preferably, improved as one kind, limited block is provided with the outside of machining position.Herringbone bear when rotated, easily from plus
Slid on station, cause security incident.The limited block of setting can limit the position of herringbone bear, and effectively prevent it from dropping.
