Description

Strong staple

A kind of is power with the source of the gas, the metal buckle of definite shape can be clamped in the powerful bringing clamping apparatus of workpiece, belongs to the portable light-duty field of tool of hardware ﹠ tools class.

In installation exercise, often the metal buckle of definite shape need be clamped in workpiece, workpiece is linked together, for example in the construction and installation operation, need to use the U-shaped buckle with plate and plate, wallboard and ground, wallboard and top board etc. firmly links together; Need sofa in the furniture industry, the spring in the mattress installs and fixes with the metal buckle.For this reason and the instrument of design has the installation of ordering of furniture industry, the special-purpose clamping device of the combined wall board in the building industry etc., there are some deficiencies in prior art; Above-mentioned order installation buckle vertically can only be ordered into, can not make it crooked; Above-mentioned special-purpose clamping device complex structure, volume is bigger, can not a tractor serves several purposes.

The purpose of this utility model provides a kind of improved powerful bringing clamping apparatus, and rational in infrastructure, volume is lighter, and is easy to use, can make buckle bending chucking workpiece, and the energy a tractor serves several purposes, is fit to wider use occasion.

Used technical scheme is that powerful clamping device is designed to pistol-shaped, adopt the impact type cylinder of horizontal positioned (relatively vertically handle), directly piston rod is used as penetrator ram, the impulsive force that cylinder is produced is used to make the buckle distortion, make it to tighten workpiece, can reduce transmission loss; Being commutated by automatically reset two five-way valves realization of air pressure of plate machine promotion adopted in gas circuit control, simplifies the structure, and sinciput is chewed to changeing structure, and the conversion top is chewed and can be used in multiple occasion.

It is less to the utlity model has volume, and weight is lighter, exert oneself big, efficient advantage high, easy to use, and the scope of application is wide, can a tractor serves several purposes.

This specification has following accompanying drawing:

Fig. 1 is powerful clamping device structural representation, shows nature (inoperative) position;

The same Fig. 1 of Fig. 2 shows the operating position;

Powerful clamping device is mainly by handle 7, cylinder 15, and push rod 17, sinciput chews 19, magazine 21, plate machine 25, reversal valve 26 is formed, and is pistol-shaped.Handle 2 is a cancelled structure, and its internal cavities 3 bottoms connect gas source connector 1, the air chamber 8 of air-flow 7 connection air reservoirs 10 through the aperture, the inner chamber of 4 connection reversal valves 26 through the aperture.In the separate cavities 32 of handle middle part, there is aperture 34,35 to connect commutation valve body 27 inner chambers respectively; Other has aperture 33 to lead to atmosphere; Cylinder 15 relatively vertically handle 2 is a horizontal positioned, and an end of its inside handle 2 is equipped with air reservoir 10, and the rear end seals with end cap 9.Air chamber 8 middle parts of air reservoir have aperture 23 to connect cylinder 15 inner chambers, and aperture 23 areas are much smaller than the area (for example 1:10) of piston 14; There is sealing gasket 11 in its exit; In cylinder 15 inner chambers piston 14 is housed, flexible 13 of its outer, sealing gasket 12 is equipped with in the face of sealing gasket 11 places of air reservoir 10 in its center; Piston rod is that an end of push rod 17 is connected with piston 14, and the other end is stretched out by sealed bearing 16, aligns sinciput through the outlet of magazine 21 and chews 19; Sinciput is chewed 19 and is contained between two outer panels 18 that are connected in cylinder 15, and with screw 20 and cylinder 15, magazine 21 connects as one, and can change; Reversal valve 26 is by valve body 27, valve rod 28, and end cap 29 is formed, and is contained in the middle part of handgrip 2, and the outer external part of valve rod 28 is relative with the plate machine 25 that can rotate on being contained in handle 2; There is the aperture to communicate with the aperture 4,34,35 of handle 2 and the aperture 22,24 at cylinder 15 inner chamber two ends respectively in the valve body 27; Valve rod 28 has garden annulated column plug 5,30, and elastic component 6,31 is housed in its garden annular groove; At two extreme positions that valve rod 28 moves, elastic component 6,31 is respectively with an obstruction in the aperture 34,35, and makes and do not stop up the aperture and be communicated with one of corresponding aperture 22,24, cylinder two ends; The buckle 36 of chucking workpiece 37 usefulness is housed in the magazine 21, is promoted by spring (not showing on the figure), the similar firearms cartridge clip of structure does not describe in detail herein.

Existing description operation process.The compressed air that the pressure of being supplied with by source of the gas the is about 0.5MPa joint 1 of flowing through enters the inner chamber 3 of handle 2, connect air storage chamber 8 and reversal valve 26 respectively by aperture 7 and 4, when plate machine 25 (see figure 1) in the raw the time, reversal valve 26 leads to aperture 22 connections of cylinder ante-chamber, and air-flow enters cylinder 15 ante-chambers and air storage chamber 8 simultaneously; The air-flow of cylinder back cavity 24,34,33 is discharged and pressure release through the aperture, and piston 14 retreats when sealing

gasket

12 and 11 compresses, and with aperture 23 sealings, the pressure in this moment cylinder 15 inner chambers and the air storage chamber 8 are equal, and piston 14 is in (work) state that resets.(see figure 2) behind the moving plate machine 25 in building, the valve rod 28 of reversal valve moves backward, sealing air-flow aperture 4 makes cylinder 15 ante-chambers stop air feed, sealed vent ports 24 simultaneously, cylinder 15 ante-chamber air-flows 22,35,33 pressure releases this moment through the aperture, make cylinder after cavity pressure greater than ante-chamber, piston 14 begins to travel forward, when piston left air reservoir aperture 23, piston 14 was increased to whole pressurizeds suddenly by small size pressurized (about gross area 1/9), and push rod 17 has obtained big power and moved forward.Buckles 36 in the magazine 21 are pushed into the position that combines with workpiece 37, chew at push rod 17 and sinciput under 19 the acting in conjunction,, reach the work purpose workpiece 37 chuckings.Unclamp plate machine 25 afterwards, air-flow 4 enters commutation valve body 27 through the aperture, and plate machine 25 is resetted, and cylinder 15 ante-chambers 22 recover ventilation through the aperture, connect vent ports 24,34,33 simultaneously, and piston 14 is resetted as Fig. 1, have finished a working cycles.
