Description
Art
The invention belongs to quartering hammer technical field, particularly relate to a kind of band and peel off the drill steel of function.
Background technology
At present the drill steel of quartering hammer can only impacting object, make object crush, in actual mechanical process, crushed
Stone can be made drill steel cannot accurately aim at break-up point without cleaning out in time, hits next time；When object
When being crashed to pieces, be further continued for shock and can cause precursor and main body loosened screw and impaired, serious in the case of also can undermine engineering machine
Tool body；If when crushing operation is carried out, drill steel is rocked and uses the stone broken with cleaning by attempt, and main body screw will with drill steel
There is the possibility ruptured.
The present invention designs the drill steel of a kind of band stripping function and solves as above problem.
Summary of the invention
For solve drawbacks described above of the prior art, the present invention disclose a kind of band peel off function drill steel, it be employing with
Lower technical scheme realizes.
A kind of band peel off function drill steel, it is characterised in that: it include trigger plectrum, stripping film, stripping head, drill steel shell,
Drill steel top cover, bearing rod, bearing rod back-moving spring, the first snap ring, the second snap ring, stripping energy-stored spring, the 3rd snap ring, bearing rod
Set, retainer ring, stripping push rod, hole clipping, stripping installing hole, stripping film rotating shaft, slide key, fixing hole, sliding tray, kayser fixture block,
Kayser back-moving spring, push rod revolute pair, fixture block locating part, fixture block chute, plectrum chute, locating part chute, wherein drill steel shell
Top is provided with drill steel top cover, and the bottom of drill steel shell is provided with stripping head, and drill steel shell is internally installed bearing rod；Drill steel top cover,
Bearing rod back-moving spring, the first snap ring, the second snap ring, stripping energy-stored spring, the 3rd snap ring are sequentially arranged at load from top to bottom
On bar, the first snap ring and the second snap ring are fixed on bearing rod, and the 3rd snap ring is arranged on bearing rod set top, bearing rod reset bullet
Spring is arranged between drill steel top cover and the first snap ring, peels off energy-stored spring and is arranged between the second snap ring and the 3rd snap ring；Load
The lower end of bar is provided with two slide keys symmetrically, has two sliding trays, bearing rod lower end the internal symmetry of bearing rod set
Being arranged in bearing rod set, slide key slides in sliding tray；The bottom of bearing rod set is provided with retainer ring, and retainer ring circumference is all
Even having four fixing holes, four identical stripping push rods are arranged on below retainer ring, peel off push rod for any one,
Its one end is arranged on the fixing hole hole wall of retainer ring by circular hole, and the other end is arranged in stripping film by push rod revolute pair
Side；Stripping film has four, and four stripping films are identical pentagon, and for any one stripping film, it passes through stripping film
Rotating shaft is arranged on stripping head, stripping head has four identical stripping installing holes, at the bottom of the stripping installing hole of stripping head
Having four hole clippings inside end, the inner side of stripping film has fixture block chute, and kayser back-moving spring is arranged in fixture block chute, kayser
Back-moving spring one end is provided with kayser fixture block, and kayser fixture block slides in fixture block chute, and two fixture block locating parts are installed symmetrically
In kayser fixture block both sides, the inside of stripping film has two locating part chutes, and fixture block locating part slides in locating part chute, stripping
Have plectrum chute from the outside of sheet, trigger plectrum and be arranged on kayser fixture block and stretch out from plectrum chute.
In the present invention, bearing rod stretches out a bit of from drill steel top cover, and impact hammer moves downward and first can strike drill steel
In bearing rod, bearing rod is moved downward by impact force, and impact hammer strikes drill steel top cover afterwards, and whole drill steel is transported downwards
Dynamic；During bearing rod moves downward, bearing rod back-moving spring is stretched, and peels off energy-stored spring and is compressed, and bearing rod is holding
Slide downward in power bar set, can will peel off pushing away of energy-stored spring by the 3rd snap ring, bearing rod set, retainer ring, stripping push rod
Power is delivered on stripping film, but owing to the kayser fixture block on stripping film is stuck in hole clipping, even if stripping film is by peeling off push rod
Thrust also cannot rotating opening；When drill steel strikes object, the triggering plectrum on stripping head also can strike object, triggers and dials
Sheet is acted on upward sliding in plectrum chute by power, and the kayser fixture block being simultaneously connected with triggering plectrum is in fixture block chute
Upward sliding, kayser back-moving spring is compressed, and kayser fixture block removes from hole clipping, and stripping film is just in the effect peeling off push rod thrust
Under eject from peeling off installing hole, now peel off energy-stored spring and elastic force discharged, peeling off push rod can rotate around retainer ring, now
Peeling off the angle increase that push rod opens for four, the stone being broken will be stripped sheet and peel away from break-up point.Load afterwards
Bar can under the effect of bearing rod back-moving spring pulling force return, the second snap ring moves upward, peel off energy-stored spring be stretched, the 3rd
Snap ring is driven bearing rod set to move upward by the pulling force effect peeling off energy-stored spring, peels off the angle opened of push rod for four and subtracts
Little, stripping film is withdrawn in stripping film installing hole, kayser fixture block comes back in hole clipping.
As the further improvement of this technology, above-mentioned fixture block chute, plectrum chute, locating part chute communicate.Due to
Kayser fixture block, triggering plectrum, fixture block locating part three are connected, when triggering plectrum upward sliding in plectrum chute, and kayser
Fixture block is upward sliding in fixture block chute, and fixture block locating part is upward sliding in locating part chute.
As the further improvement of this technology, above-mentioned stripping push rod is turned on fixing hole, on bearing rod by revolute peace
During lower motion, peeling off push rod can rotate in retainer ring.Stripping push rod is turned out, can be by stripping film from peeling off installing hole
Releasing, stripping film is turned out around stripping film rotating shaft；Peel off push rod to rotate inwards, can be returned to stripping film peel off installing hole
In, stripping film rotates inwards around stripping film rotating shaft.
As the further improvement of this technology, the shape phase being shaped as pentagon and stripping film of above-mentioned stripping installing hole
With.
Relative to traditional quartering hammer technology, the present invention is provided with stripping film on the stripping head of drill steel, when drill steel is downward
When hitting object, triggering plectrum and moved upward by the resistance of object, stripping film is just from peeling off ejection installing hole, by the most broken
Object from break-up point peel off；Drill steel in quartering hammer is transformed by the present invention, quartering hammer can be made to exist by stripping film
While broken object, broken object is peeled off, make break-up point have the preferable visual field, there is stronger practical function.
