Abstract

The utility model discloses a mechanism for taking out or pulling in hollow rivet for pneumatic gun. The commonly used core loosing rivet air powered gun has the problem that the broken nail cores scatter everywhere after rivet pulling so as to cause environment pollution. The utility model is mainly characterized in that the gun barrel of the core loosing rivet air powered gun which consists of a gun barrel, a gun body and a gun handle is additionally provided with an absorbing and spitting mechanism consisting of a nail spitting pipe and a nail spitting linking pipe which is sleeved out of the nail spitting pipe; the air inlet pipe of the gun handle is additionally provided with an absorbing and spitting control mechanism consisting of a nail spitting control rod and a rivet cover. The utility model has the advantages of simple structure, convenient use and no pollution, which is suitable for the riveting processing operation.

Description

Mechanism is told in the suction of self-plugging rivet pneumatic gun

The utility model relates to a kind of self-plugging rivet pneumatic gun, and mechanism is told in the suction that particularly relates to a kind of self-plugging rivet pneumatic gun.

Existing self-plugging rivet pneumatic gun adds man-hour riveting, and after the self-plugging rivet staking, the shaft of rivet expands, workpiece is fastening, and nail core fracture for the nail core of fracture, needs the rolling self-plugging rivet pneumatic gun that makes a movement, the nail core just can be deviate from the muzzle of self-plugging rivet pneumatic gun, like this, not only increase the operation of operation, reduced operating efficiency, and, also polluted surrounding environment.

The purpose of this utility model is to provide a kind of suction of improved self-plugging rivet pneumatic gun to tell mechanism, and it can not only realize protecting surrounding environment to exempt from pollution, and, can also enhance productivity effectively.

As follows in order to realize above-mentioned purpose design of the present utility model: the suction of self-plugging rivet pneumatic gun of the present utility model is told mechanism and is had the rifle body that is provided with a cylinder, gas circuit, piston and nail tube in the body, the front end end of described rifle body is connected with a gun barrel, be provided with a rivet seat in the front end body of described gun barrel, be provided with a spring spool in the described gun barrel rear end element, the bottom of described rifle body is connected with a pikestaff, is provided with an air inlet pipe and press button in the body of described pikestaff.The nail tube mouth place of the end, rear end of described rifle body is provided with a storage barrel, be equipped with a suction in the spring spool in the described gun barrel and tell mechanism, described suction is told mechanism and is constituted by telling the nail pipe and telling the nail joint pipe, described two sides of telling the front end end of nail joint pipe are provided with an air admission hole, the place, end, upper end of the air inlet pipe in described pikestaff one lateral body is provided with a suction and tells controlling organization, described suction is told controlling organization and is formed by telling nail control lever and riveting lid, and described telling on two ends of following closely control lever all is equipped with " O " shape Mi Quan.

Because the utility model improved existing self-plugging rivet pneumatic gun, adopt the pneumatic jet principle, in the self-plugging rivet pneumatic gun, have additional one and inhale and tell mechanism and controlling organization is told in suction, thereby simplified operating procedure greatly, also improve the efficient of work, simultaneously, improved the pollution of environment.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation that mechanism is told in the suction of self-plugging rivet pneumatic gun of the present utility model.

Fig. 2 is that schematic diagram is looked on the right side of Fig. 1.

Fig. 3 is the local enlarged diagram that mechanism is told in suction of the present utility model.

Below with reference to accompanying drawing mechanism being told in the suction of self-plugging rivet pneumatic gun of the present utility model is described in further detail.

With reference to Fig. 1, Fig. 2 and Fig. 3, the suction of self-plugging rivet pneumatic gun of the present utility model is told mechanism and is made up of rifle body (1), gun barrel (3) and pikestaff.

Be provided with a cylinder, gas circuit, piston and nail tube in the body of described rifle body (1), the nail tube mouth place of the end, rear end of described rifle body (1) is equipped with a storage barrel (6).

Referring to Fig. 1 and Fig. 3, be provided with a rivet seat in the front end body of described gun barrel (3), device has a spring spool (2) in the rear end element, put into one in the spring spool (2) in the body of described gun barrel (3) and told nail pipe (7), described to tell nail pipe (7) be to be inserted in to tell in the nail joint pipe (8), and described two sides of telling the front end end of nail joint pipe (8) are respectively equipped with an air admission hole (8).

Referring to Fig. 1 and Fig. 2, be provided with an air inlet pipe (4) and press button (5) in the body of described pikestaff, the place, end, upper end of the air inlet pipe (4) in the described pikestaff body is equipped with one and tells nail control lever (10), described two ends of telling on the nail control lever (10) dispose one " O " shape Mi Quan, and described end, outer end of telling nail control lever (10) is installed on riveting lid (11).

Connect source of the gas before the use, when arriving required amount of gas pressure, the nail core of self-plugging rivet can be inserted in the rivet seat of self-plugging rivet pneumatic gun muzzle, the nail body of self-plugging rivet inserts in the workpiece hole that needs riveted joint, pull press button (5), the compressed air gas circuit of flowing through, the back is by the slit of described spring spool (2), enter from the described air admission hole (8) of telling front end end two sides of nail joint pipe (9), form high velocity air this moment, causes gun barrel (3) front end negative pressure and cavity, thereby produce swabbing action, hold the nail core of self-plugging rivet, make the nail volume expansion of self-plugging rivet, break until the nail core of self-plugging rivet, workpiece is fastening, the nail core that breaks is then followed air communication again and is crossed the interior nail tube of rifle body (1), spits in the storage barrel (6) from the nail tube mouth.

In addition, also can tell controlling organization by suction operates, random so strong, can save source of the gas, when needing suction, press the riveting lid (11) of telling nail control lever (10), promote the described nail control lever (10) of telling, open the air inlet pipe (4) in the described pikestaff body, tell mechanism by suction and aspirate, in the time of stopping, bleed off immediately conveniently and stop, when telling nail as need, same, press riveting lid (11), the nail core that will break is spued effectively from the nail tube mouth, enter in the described storage barrel (6), can unload after described storage barrel (6) is filled, so that focus on.
