Abstract
The utility model discloses a pneumatic nailing machine. A switch valve is arranged on the left end of the air inlet cavity of the machine body of the pneumatic nailing machine, a valve hood is arranged on the upper part of the switch valve, and the lower part is provided with a valve body; the inner cavity of the valve body is provided with a valve rod, and a spring is arranged between the valve hood and the valve rod; the lower part of a contact arm is sheathed on the outside of a machine head. The action of a piston and a rush rod of the pneumatic nailing machine is accurate. The phenomena that many nails are hammered or no nail is hammered, which are caused by the high-low variation of the atmospheric pressure of compressed air are avoided. In addition, the pneumatic nailing machine can not act by a mistake when the contact arm of the pneumatic nailing machine is not pressed toward workpiece surfaces, so safe operation is ensured. The utility model has high work efficiency, and can nail various wooden wares.
Description
The utility model relates to a kind of carpenter's nailing instrument.
Known pneumatic stapler (producing " N80S-1 " pneumatic stapler) as the U.S., be compressed air from back body, enter the cylinder inner top through switch and promote piston and drive the jumper bar nailing.The switch of this nailing machine is controlled inaccuracy to compressed air, and at compressed air air pressure when higher or low, nailing machine is prone to the many nailings or the phenomenon of nailing not.And do not have safety guard, the easy misoperation of nailing machine causes the accident.
The purpose of this utility model provides a kind of pneumatic stapler, and it can adapt to the variation of compressed air height, can avoid many nailings, not nailing and misoperation phenomenon.
The purpose of this utility model is achieved in that at the inlet chamber left end of a fuselage installs a switch valve, and switch valve top is valve bonnet, and the bottom is a valve body, and body cavity is adorned a valve rod, adorns a spring between valve bonnet and the valve rod.
Valve bonnet is enclosed within valve body top, and there is a groove in the valve bonnet outside, cover one sealing ring in the groove, and there is a pore at center, valve bonnet top.Side, valve body middle part has pore to communicate with body cavity, and there is low groove on the twice valve body lower portion side, is with a sealing ring in the upper groove, has pore to communicate with body cavity in the low groove, and there is a circular hole at the valve body lower end center.Valve rod in the body cavity stretches out in the circular hole at valve body lower end center, and the twice groove is arranged at valve rod top, is with sealing ring in the groove, valve rod middle part cover one sealing ring.The valve rod lower end is positioned at above the contact lever.
Contact lever is positioned at above the starter, and the contact lever right-hand member connects the starter right-hand member, and the starter left end links to each other with fuselage, and contact lever gives on contact arm upper end.
Contact arm middle bent, contact arm bottom are enclosed within the head outside, and lower left side has a spring abutment, adorn a compression spring on the spring abutment, and compression spring upper end presses closer head.
Owing to adopted technique scheme, make the piston of nailing machine and jumper bar action accurately, stopped just to change the many nailings that cause or the phenomenon of nailing not because of compressed air air pressure.And when the contact arm of nailing machine was not pressed to surface of the work, nailing machine can misoperation, has guaranteed safe handling.Its high efficiency can be followed closely the various wooden utensils of system.
Elaborate below in conjunction with drawings and Examples.
