Description
Technical field
This utility model relates to a kind of electric nail gun, particularly relates to a kind of electric nail gun using air spring.
Background technology
The air spring ailing machine of a kind of early stage is disclosed in United States Patent (USP) US4215808 of Sollberger.
The patent of Sollberger is to use a tooth bar and a little gear that piston is recommended ready position.One separate bendable
Bent mechanical cable is then used to the machinery output of motor be driven the pinion-gearing of nail gun by a drive system.
Another kind of air spring ailing machine is disclosed in United States Patent (USP) US5720423 of Kondo.The patent of this Kondo
Use one separate to have the air that an air supplements piston and replenish the supply groove, be used for supplementing and drive required for a piston
Forced air, this forced air then then a nail is squeezed in object.
Another kind of gas spring ailing machine is disclosed in open U.S. patent application case US20060180631 of Pedicini
In, this instrument uses a tooth bar and little gear that piston is moved back into ready position.Tooth bar and little gear are at power stroke
Period is by decoupling.The instrument of Pedicini employs pressure relieving valve to replenish the air lost during nail drives.
Another kind of gas spring ailing machine is disclosed in United States Patent (USP) US8011547 of Senco, and this instrument uses air pressure bullet
Spring principle provides quickly downwards power stroke, and uses the rotation of a cam face to straighten wire type to recommend device, and this carries
Lift and there is on the circumferential surface of device multiple cylindrical projection pins, use the multiple rotary recommending device to be recommended by nailing component
Return ready position, and device will be recommended by one way feature and be held in a predetermined position；Also there is a cylinder and an air storage chamber, and
The volume of air storage chamber is at least 2:1 with the displacement volume ratio of cylinder, and its forced air uses special inflation at the very start
Equipment is filled in air storage chamber, and does not has air compensating system on this instrument.Its shortcoming is have compressed gas to be stored in storage all the time
In air chamber, there is the potential safety hazard of blast in the leakage that once collides；Even if in off working state, its one way feature is in all the time
Under the high voltage load of air spring, it is easier to wear out failure, once lost efficacy and mistakenly hit will be caused to send out；This tool construction seems simple, but
The highest to the sealing requirements of instrument, manufacture process difficulty, and piston packing as the dynamic seal of Long travel repeatedly
Working in reciprocating mode after be bound to abrasion, the forced air deposited can reduce rapidly or even leak completely and make tool failures, lost efficacy
Rear operator cannot keep in repair because not possessing charger.
The nailing component of Senco patent has at least the first longitudinal edge, and it is arranged essentially parallel to being positioned at of nailing component
The direction of motion between drive position and ready position, has the projection at several interval, recommends under the effect of high pressure gas spring
The projection contacts at device and interval is recommended nailing component and is resetted, and inserted pins is conflicted with space protrusion and prevented nailing component from falling after rise.The
One longitudinal edge includes that two are parallel to each other and identical left side longitudinal edge and right side longitudinal edge, wherein left side edge
Projection and the cylindrical projection pin recommended on device interact, the projection in right side edge interacts with inserted pins.Carry
The cam edge lifting device is divided into the section of recommending and the section of coming to nothing, and the section of recommending is provided with several cylindrical projection pins, cylindrical projection pin
It is sequentially inserted into the projection of left side edge, recommends nailing component；And it is not provided with cylindrical projection pin in the section of coming to nothing, for nailing component
Action slot milling.There is the gap recommending device disengaging nailing component between the adjacent cylindrical projection pin recommending device, now go up
One cylindrical projection pin has been moved off space protrusion, and next cylindrical projection pin not yet inserts space protrusion, in gap
Phase nailing component relies on inserted pins to support, and prevents nailing component from driving in the wrong direction under pneumatic pressure；The cylindrical projection pin at end is with first
Between cylindrical projection pin, form the section of coming to nothing.Its shortcoming is: nailing component is by the interval of left side longitudinal edge during recommending
Projection can stand to recommend the continual shock of device；In the gap phase, the space protrusion of right side longitudinal edge can be impacted inserted pins, be beaten
It is more that the space protrusion on the right side of nail component accepts to clash into number of times, is easily bent deformation and damages, causes tool failures.
Senco patent also has an inserted pins, (the now motion side of nailing component when nailing member drives nailing
To being first direction), the segregation apparatus of solenoid control, and be forced into non-contacting position, thus its card plane is not
Can conflict with several space protrusion of nailing component；(the now motion side of nailing component when nailing component returns ready position
To being second direction), segregation apparatus discharges again its inserted pins, and inserted pins is directed towards screens position, simultaneously latch structure
The sliding surface of part allows the projection at several intervals of nailing component to move against inserted pins, and the card plane of inserted pins is at nailing
Screens is carried out, it is ensured that will not fall when nailing component moves in a second direction below the space protrusion of component.Its shortcoming is
Segregation apparatus uses solenoid controlled, and owing to this instrument operationally shakes very big, and solenoid installation site is close
The impact end of nailing component, the line of solenoid is easy under huge vibrations sealing-off or broken string and makes tool failures, condition
And the manufacturing cost of solenoid is significantly larger than mechanical part, this adds the most again the cost of instrument, also accelerates simultaneously
The loss of tool batteries electricity, decreases the nailing number of times of a charging cycle, reduces the service life of battery.
The another drawback of Senco patent is that the required precision to parts is the highest, it is impossible to adapt to poor environment, dynamic
Make reliability poor.Recommend the friction repeatedly of the space protrusion of the cylindrical projection pin of device and nailing component and shock, easily grind
Damage, and make nailing component to recommend and put in place, cause its inserted pins to cannot be introduced among the screens of space protrusion, thus cause
Tool failures；The abrasion of the cylindrical projection pin recommending device also result in recommend when needs nailing device cannot upwards trace recommend beat
Nail component puts in place, and the projection of the bottom of the card plane of inserted pins and nailing component cannot depart from conflict, and nailing component exists
Still fasten inserted pins under pressure-air effect, make the segregation apparatus of solenoid cannot pull open inserted pins, now electromagnetic wire
Circle will burn because load is excessive, and instrument lost efficacy immediately.
