Description
Technical field
The present invention relates to impact wrench fields, more specifically, it relates to a kind of striking structure of impact percussive machine.
Background technology
Impact wrench is to be rotated by compressed gas-driven Pneumatic motor mechanism, then exported to striking mechanism by rotor,
Striking mechanism drives main shaft to form the rotary motion to move in circles, and for impact wrench, the lubrication quality of striking mechanism
Service life is directly influenced, the lubricant on traditional impact wrench would not remain in striking mechanism, to loss or heap
Product on wall, causes lubricant effect to decline inside the shell, and mechanical wear reduces the service life, so application No. is
200780035844.8 Chinese patent discloses a kind of impact wrench of the beater mechanism with lubrication, passes through lid member
Part plays certain sealing function, avoids the loss of lubricating grease, but the inertia drive member on the impact wrench is to pass through
Drive sleeve and hammer element are connected to motor, on the one hand since drive sleeve rotation also needs to be lubricated, therefore the patent
Cover element its with drive sleeve by clearance seal, clearance seal first can only be sealed lubricating grease, can not be right
Lubricating oil is sealed, and lubricating grease is in solid or semifluid shape, and viscosity is big, and the lubricant effect on the component of rotation is not as good as lubrication
Oil is good, and clearance seal is very high to surface processing accuracy requirement, and processing is relatively difficult to cause of high cost, on the other hand strike
Mechanism and the contact area of main shaft are small, and impact area is smaller, and then strike breaks out force difference and power is small, is only applicable to low power
Pneumatic impact spanner.
Invention content
In view of the deficiencies of the prior art, the present invention intends to provide, one kind having more applicability and sealing effect is good
Impact percussive machine striking structure.
To achieve the above object, the present invention provides following technical solutions：A kind of striking structure of impact percussive machine,
Including main shaft, impact frame, impact sleeve and air motor linkage and the taping block for hitting main shaft, the taping block setting is being impacted
In frame, the sealing cover of sealing impact frame side is arranged on the main shaft, the other side of the impact frame is equipped with spline, described
The junction of spline and impact frame is equipped with sealing ring, and the inner surface and the outer surface of the sealing cover is arranged with sealing ring.
Further, the sealing cover is equipped with oil filler point, and stifled whelk silk, the stifled whelk silk are equipped in the oil filler point
On be arranged with sealing ring.
Further, axle sleeve is arranged on the main shaft, the axle sleeve between sealing cover and main shaft, the axle sleeve with
Sealing ring is provided between sealing cover.
Further, described taping block one end passes through impact sleeve and impact frame by spline and impact frame linkage, the other end
Linkage, the taping block setting are hit there are one and to single beat of main shaft progress.
Further, the taping block includes strike body and shank, and the shank is wholely set with strike body, the impact
It is equipped with the card slot being clamped with shank on set and spline.
Compared with the prior art, the advantages of the present invention are as follows：By the way that sealing cover and flower is respectively set in the both sides of impact frame
Key is sealed impact frame, sealing ring is arranged in the junction of spline and impact frame, the inner surface and the outer surface of sealing cover is equal
It is equipped with sealing ring, to carry out comprehensive sealing effect to entire striking structure, the case where since there is no clearance seal, therefore
Lubricating oil can be sealed, there is the case where rotation strike in striking structure, therefore effect is lubricated by lubricating oil
More significantly, it and is avoided that the loss of lubricating oil, striking structure can be lubricated well for a long time, avoid the machinery mill of component
Damage, greatly extends service life.

Specific implementation mode
The striking structure embodiment of impact percussive machine of the present invention is described further to Fig. 4 referring to Fig.1.
A kind of striking structure of impact percussive machine, including main shaft 1, impact frame 2, impact sleeve 3 and air motor join
Taping block 4 that is dynamic and hitting main shaft 1, the setting of taping block 4 are arranged with sealing impact in impact frame 2 on main shaft 1
The other side of the sealing cover 5 of 2 side of frame, impact frame 2 is equipped with spline 6, the junction of spline 6 and impact frame 2
Equipped with sealing ring 7, the inner surface and the outer surface of sealing cover 5 is arranged with sealing ring 7.
The both sides for impacting frame 2 are carried out by spline 6, sealing cover 5 and sealing ring 7 thereon comprehensive close
Envelope, and then the lubricating oil impacted in frame 2 is not easy to be lost in during the work time, striking structure can adequately be lubricated, and
Lubricating oil in impact frame 2 can be stored in inside for a long time to be lost in, and then avoid the mechanical wear of internal part, pole
Big extends service life.
Wherein sealing cover 5 is equipped with oil filler point, and stifled whelk silk 8 is equipped in oil filler point, is arranged on stifled whelk silk 8
Sealing ring 7, there are two preferred oil filler point settings and is symmetrical arranged, and by the setting of oil filler point, impact wrench is used for a long time
It afterwards,, only need to oiling be just by oil filler point without dismantling entire spanner when impacting lubrication oil consumption in frame 2 totally
It can realize operation, operate simpler convenience, stifled whelk silk 8 is screwed on after the completion of oiling and blocks oil filler point, by blocking up whelk
Sealing ring 7 on silk 8 is sealed, the case where avoiding impacting the outflow of lubrication oil in frame 2.
Axle sleeve 9 is arranged on main shaft 1, axle sleeve 9 is between sealing cover 5 and main shaft 1, axle sleeve 9 and sealing
Sealing ring 7 is provided between lid 5.
The setting of axle sleeve 9 can avoid sealing cover 5 from directly contacting the case where causing abrasion oil leak with main shaft 1, and
And axle sleeve 9 can reduce load friction coefficient so that main shaft 1 good can rotate, in axle sleeve 9 and sealing cover 5
Between sealing ring 7 is set, good sealing effect can be played, avoid lubricating oil in impact frame 2 from axle sleeve 9 with it is main
The junction of axis 1 leaks, and increases leakproofness.
Above sealing ring 7 is O shape sealing rings 7, and it is installed in the hook slot of annular, and stability is good, and
And 7 sealing effect of O-ring seals is good, at low cost and friction of motion resistance very little, is suitable on the striking structure.
4 one end of taping block is linked by spline 6 and impact frame 2, and the other end passes through impact sleeve 3 and impact frame 2
Linkage, there are one the settings of taping block 4 and carries out single beat to main shaft 1 hits, and taping block 4 includes strike body 41 and shank
42, shank 42 is wholely set with strike body 41, and the card slot being clamped with shank 42 is equipped on impact sleeve and spline 6.
It is hit since taping block 4 is provided with one piece and carries out single beat to main shaft 1, such taping block 4 and main shaft 1
Contact area can be arranged larger, and then impact area is big, and strike explosive force is strong and power is big, can be suitable for high-power
Pneumatic impact spanner, it is traditional that there are taping blocks 4 and impact frame 2 to be attached by pin, once and then pin lose
Effect, striking structure just can not normal use therefore by the way that shank 42 and taping block 4 to be wholely set be not in pin appearance
Vulnerable situation, thereby using longer life expectancy and stability it is more preferable.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
