The gas automatic-reset nailing gun has the advantages that: while ensuring the predetermined effects, a fixed quantity of gas is used as the launch power, therefore the automatic reset of the workpiece and the automatic positioning of the nail is achieved; the purpose of high-strength continuous operation is achieved; the standard strength of launching nail is ensured; at the same time, labor intensity is reduced, the expenditure of time is cut down, and mis-launching that hurts people will further be prevented, which is much safer.

Description

The combustion gas ailing machine that automatically resets

Affiliated technical field

The utility model relates to a kind of ailing machine.

Background technology

Ailing machine claims nailed apparatus again.It is to utilize powerful air pressure that powder gas or air pump (air compressor machine) produce as power, drives the piston in the nail rifle, and the piston motion is injected into instrument in the matrix with nailing.Because it is convenient and strength-saving that it has, and is widely used in the various engineering processes.The ail gun that present stage uses, no matter be to be power with gunpowder or Compressed Gas, all exist common shortcoming: the ability of working continuously causes efficient low relatively, because after piston moves to stop, must there be an external force that it is resetted, just can enter next working cycles, this external force all is to rely on manual finishing, and nail also is that simple grain is packed into, increased operator's physical load so on the one hand, also lost the working time.

Summary of the invention

The purpose of this utility model provides a kind of can automatically reseting, and realizes that the combustion gas of working continuously automatically resets ailing machine to remedy the deficiency of prior art.

The technical solution adopted in the utility model is: the combustion gas ailing machine that automatically resets, comprise rifle body, trigger assembly, nail casket, and it is characterized in that: be provided with piston cylinder in the rifle body, piston is arranged in the piston cylinder, piston moves back and forth in piston cylinder under gas pressure.

Good effect of the present utility model is: the utility model is guaranteeing to set under the prerequisite of effect, utilize quantitative combustion gas as launch power, thereby realized the automatic in-position that automatically resets and follow closely of workpiece, reached the purpose that high strength is worked continuously, also guaranteed the standard dynamics of nailing; Reduce labour intensity simultaneously, reduced expenditure of time, more can not produce and mistakenly launch the phenomenon of hurting sb.'s feelings, had more security.

The specific embodiment:

Embodiment:

The combustion gas ailing machine that automatically resets comprises rifle body 1, trigger assembly 2, nail casket 3, and the rifle body is provided with piston cylinder assembly 4, and piston cylinder assembly 4 front ends have gun platform 5, and piston cylinder assembly 4 is outer to be with cylinder sleeve 6, is fixed with end cap 7 behind the rifle body 1; Piston component 8 is arranged in the piston cylinder assembly 4, sealing ring 9 is arranged behind the piston component 8; Gun platform 5 is connected with piston cylinder assembly 4; Cylinder sleeve 6 and position restoring claw 11 are connected, and are provided with back-moving spring 11 between piston cylinder assembly 4 and the position restoring claw 27; The nail hole 12 that nail groove 28 is into arranged in the gun platform 5 and adapt to piston component 8; End cap 7 built-in motors 13, motor 13 drive fan 14, end cap 7 inboards are provided with igniting travel switch 15 and sealing ring 16; Rifle body 1 is arranged with fuel gas bottle storehouse 17, and constant volume air valve 18 is arranged in the combustion gas storehouse 17; Inlet channel 19 is arranged in the end cap 7; Rifle body 1 is arranged with battery compartment 21.

Ail gun is positioned at free state at ordinary times, and fuel gas bottle places in the fuel gas bottle storehouse 17, and constant volume air valve 18 tightly is enclosed within on the fuel gas bottle, and the front end valve of constant volume air valve 18 is in closed condition, the rear end valve opening, and the gas in the fuel gas bottle enters in the valve body.Simultaneously, cylinder sleeve 6 is to be in preceding stop; Row's nail 26 is arranged in the nail hole 12.

During use,, by push rod component 10, position restoring claw 27, power is delivered to cylinder sleeve 6 then, makes cylinder sleeve 6 move backward to the back stop with force compresses nail pipe box 29.

When cylinder sleeve 6 arrived the back stop, the rear end of cylinder sleeve 6 pushed against end cap 7, simultaneously sealed circle 16 sealings; Simultaneously, the inwall of cylinder sleeve 6 is also realized sealing with sealing ring 9.Like this, piston component 8, piston cylinder assembly 4, cylinder sleeve 6, end cap 7 and sealing ring 9,16 have just formed an airtight gas explosion chamber.

With this simultaneously, move past in the journey behind the cylinder sleeve 6, the rib pushing motor on it starts travel switch 20, and the lead of motor 13 is connected, so the voltage of battery 22 rotates motor 13 drive fan 14; Rib also promotes bottle pusher 23 simultaneously, and bottle pusher 23 rotates around bottle pusher rotating shaft 24, forces in constant volume air valve 18, makes constant volume air valve 18 rear end valve closings, and the quantitative combustion gas body in the front end valve opening, valve body enters space, gas explosion chamber by inlet channel.

Then, depress trigger assembly 2, igniting travel switch 15 closures, the voltage of battery 22 makes igniting travel switch 15 arc discharges, combustion gas that gas explosion is indoor and Air mixing gas produce blast, the strength that blast produces moves forward piston component 8 rapidly, and the row that piston component 8 front ends hit in the nail hole follows closely 26, it is sent the rifle body also follow closely on matrix firmly.

Piston component 8 is in the reach process, the explosion chamber space remains sealing state, because piston component 8 reaches, the space increases, and makes that the air pressure in the space reduces, so under atmospheric pressure effect, piston component 8 can reset rapidly, simultaneously, the next ones row nail 26 in the nail casket 3 is ordered groove 28 and is entered nail hole 12 by sending automatically, waits for percussion next time.

Afterwards, rifle body 1 is removed from body surface, the elastic force of back-moving spring 11 can make cylinder sleeve 6 be advanced to preceding stop, and bottle pusher 23 resets, constant volume air valve 18 front end valve closings, and the rear end valve opening, the gas in the fuel gas bottle enters in the valve body once more.Simultaneously, sealing ring 9 and 16 does not seal, and all links to each other with atmosphere before and after the combustion chamber, because electric motor starting travel switch 20 is for postponing switch, though the circuit that resetted still is communicated with, fan 14 is rotated further, fresh air is introduced from end cap 7 backs, and the waste gas after blast top blast in the past goes out.

Above process has just formed complete working cycles.
