A kind of C sprig rifle nail circle interlock circle footpath adjusting device
Technical field
The present invention relates to a kind of pneumatic nail gun assembly, especially a kind of C sprig rifle nail circle interlock circle footpath adjusting device.
Background technology
Pneumatic nail gun is that a kind of automatic nail sandwiched is standby, and its operation principle is to utilize pressure-air that nail is passed through to rifle mouth nail clip on object.The outstanding advantages such as to have nail clip speed fast due to nail gun, and nail clip is firm, easy to use, produce so be widely used in bed net, and automobile cushion is made, and breeding cage is made, in the industries such as fence making.
According to actual nail clip needs, different adjustment need to be made in the clamping ring footpath of C type rifle nail, and the major way of controlling rifle nail interlock circle footpath is the clamping distance of controlling nail gun clamp.In existing pneumatic nail gun, the adjustment in the interlock circle footpath of rifle nail is more difficult, the nail gun of the overwhelming majority does not possess the function of adjusting rifle nail interlock circle footpath on the market, when running into the nail clip demand that needs different circles footpath, often all need to be equipped with the nail gun of different nail clip specifications, such mode of production not only reduces production efficiency, and production cost input is high, very inconvenient on production and application.

For achieving the above object, the technical solution adopted in the present invention is: a kind of C sprig rifle nail circle interlock circle footpath adjusting device, comprise: rifle body, on described rifle body, be provided with gripping mechanism and drive cylinder, described driving cylinder is located at gripping mechanism afterbody, this driving cylinder is comprised of cylinder piston rod and cylinder shell, cylinder piston rod is connected with the pushing block on gripping mechanism, it is characterized in that: in the outside of cylinder shell, afterbody is provided with adjustment seat, one end and the adjustment seat of adjusting rod are threaded connection, the other end of adjusting rod pierces into cylinder shell inner chamber, and corresponding with cylinder piston rod.
Preferably, be also provided with stop nut between described adjusting rod and adjustment seat, this stop nut is connected with adjusting rod and is close to adjustment seat.
Preferably, at described cylinder piston rod, by piston body and push rod, by interconnecting, formed, on the tail end face of piston body, be provided with detent, the laminating corresponding to detent of described adjusting rod.
Preferably, the described adjusting rod end face corresponding with detent is provided with cushion pad.
Preferably, described cylinder shell is comprised of procapsid and back casing, and procapsid is fixedly connected with rifle body, and back casing is connected with procapsid by screw, is also provided with sealing ring between procapsid and back casing.
Preferably, the reach on described adjusting rod is greater than the shift length of pushing block in gripping mechanism.
Preferably, described adjustment seat is fixedly connected with cylinder shell by screw.
Preferably, between described adjusting rod and cylinder shell, be provided with sealing ring.
The present invention adopts after said structure, by the afterbody at cylinder shell, increase adjusting lever pushing block displacement is carried out to spacing version, limited the rollback distance of pushing block, the clamping amplitude of gripping mechanism is adjusted, make C type rifle follow closely interlock circle footpath in gripping mechanism controlled, thereby realize the adjustable object of C type rifle nail circle footpath size.The present invention is simple in structure, and the interlock circle footpath of rifle nail is adjusted and respective change with the position of adjusting rod, and installation is adjusted easy.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in the figure, a kind of C sprig rifle nail circle interlock circle footpath adjusting device, comprise: rifle body 1, on described rifle body 1, be provided with gripping mechanism 2 and drive cylinder 3, described driving cylinder 3 is located at gripping mechanism 2 afterbodys, this driving cylinder 3 is comprised of cylinder piston rod 31 and cylinder shell 32, cylinder piston rod 31 is connected with the pushing block 4 on gripping mechanism 2, it is characterized in that: in the outside of cylinder shell 32, afterbody is provided with adjustment seat 5, one end of adjusting rod 6 and adjustment seat 5 are threaded connection, the other end of adjusting rod 6 pierces into cylinder shell 32 inner chambers, and corresponding with cylinder piston rod 31.
Preferably, between described adjusting rod 6 and adjustment seat 5, be also provided with stop nut 7, this stop nut 7 is connected with adjusting rod 6 and is close to adjustment seat 5.
Preferably, at described cylinder piston rod 31, by piston body 33 and push rod 34, by interconnecting, formed, on the tail end face of piston body 33, be provided with detent 35, the laminating corresponding to detent 35 of described adjusting rod 6.
Preferably, described adjusting rod 6 end face corresponding with detent 35 is provided with cushion pad 8.
Preferably, described cylinder shell 32 is comprised of procapsid 36 and back casing 37, and procapsid 36 is fixedly connected with rifle body 1, and back casing 37 is connected with procapsid 36 by screw, between procapsid 36 and back casing 37, is also provided with sealing ring 9.
Preferably, the reach on described adjusting rod 6 is greater than the shift length of pushing block 4 in gripping mechanism 2.
Preferably, described adjustment seat 5 is fixedly connected with cylinder shell 32 by screw.
Preferably, between described adjusting rod 6 and cylinder shell 32, be provided with sealing ring 9.
The outside afterbody of nail gun upper cylinder housing 32 is connected by screw adjustment seat 5 is installed, and this adjustment seat 5 is provided with a tapped through hole, is provided with equally one section of connecting thread on adjusting rod 6, and adjustment seat 5 is fastened and connected by connecting thread mutually with adjusting rod 6.One end of adjusting rod 6 is located in cylinder shell 32 inner chambers through the wall portion of cylinder shell 32, and the end of adjusting rod 6 is corresponding with piston body 33 rear end; Between adjustment seat 5 and adjusting rod 6, be also provided with stop nut 7.
In use, according to the size in the interlock circle footpath of C type rifle nail in using, adjust adjusting screw(rod) and pierce into the length in cylinder shell 32, thereby limit the rollback distance of pushing block 4.Press nail gun trigger, pressure-air enters from the back cavity of cylinder shell 32, due to the variation of the front and back pressure differential of cylinder shell 32, cylinder piston rod 31 pushes forward, cylinder piston rod 31 drives the pushing block 4 in gripping mechanism 2 to push ahead, and C type rifle nail is pushed on the predetermined clamped position of gripping mechanism 2 front ends.
Again press nail gun trigger, Manual gas valve commutation, pressure-air enters from the ante-chamber of cylinder shell 32, due to the variation of the front and back pressure differential of cylinder shell 32, cylinder piston rod 31 rollback backward, cylinder piston rod 31 drives pushing block 4 rollbacks in gripping mechanism 2, in the back off procedure of pushing block 4, roller 41 on pushing block 4 drives gripping mechanism 2 rear ends to strut, under leverage, the front end of gripping mechanism 2 draws in and clamps C type rifle nail, make C type rifle nail start interlock, when cylinder piston rod 31 drives pushing block 4 to return back to certain position, the corresponding laminating of detent 35 on the tail end face of adjusting rod 6 and piston body 33, adjusting rod 6 carries out spacing to the rollback of pushing block 4, the interlock of C type rifle nail stops and remaining on current circle footpath size.
The above is the preferred embodiment of the present invention; certainly can not limit with this interest field of the present invention; should be understood that; for those skilled in the art; technical scheme of the present invention is modified or is equal to replacement, do not depart from the protection domain of technical solution of the present invention.
