In the present embodiment, cylinder 9 in energy storage device air-tightness in guide sleeve device 11 is slided and is had first operating position and second operating position, when inverted cam 61 apart from driving cam 62 recently the time, push rod 7 is in first operating position, when inverted cam 61 apart from driving cam 62 farthest the time, push rod 7 is in second operating position.
When motor is connected the power supply running, because driven wheel of differential 5 is meshed with drive bevel gear 4 axis normal and both, to drive driven wheel of differential 5 rotations during 4 rotations of driven by motor drive bevel gear, the driving cam 62 coaxial with driven wheel of differential 5 also will rotate, supposed when this moment, push rod 7 was in first operating position, because the rotation of driving cam 62, and inverted cam 61 can not be on the push rod 7 that self axle rotates owing to being fixed on, simultaneously, driving cam 62 and inverted cam 61 are surface cylinders that scarf is complementary, so driving cam 62 can apply a thrust identical with its direction of rotation on inverted cam 61, inverted cam 61 is owing to can't rotate, so under the extruding of driving cam 62 rotations, drive the rectilinear motion that push rod 7 is done away from driving cam 62, and push rod 7 is by keeping straight line airtight motion to the direction away from driving cam 62 with piston pin 8 connecting band dynamic air cylinders 9 in guide sleeve device 11.
In the present embodiment, when driving cam 62 continues to keep rotation, and promote inverted cam 61 to direction moving linearly away from oneself, be push rod 7 by first operating position in the process of second operating position motion, push rod 7 promotes cylinder 9 and moves towards piston 10 directions, with the air applied thrust in the cylinder 9 and compress, in the process of initial compression, air is directly delivered to piston 10 with the thrust that is subjected to, promote piston 10 motions, contact with the hammer tail 123 of beating unit 12 up to piston 10, and promote beating unit 12 motions, when the limiting section 122 and the flip flop equipment 13 of beating unit 12 device 13 that contacts and be triggered stops.At this moment, the air in the cylinder begins further compression, stored energy.
After being compressed to a certain degree, after the air of cylinder 9 is compressed to a certain degree, this pressure is enough to overcome the barrier force of flip flop equipment 13, piston 10 further pushes trigger head 131 by the limiting section 122 of beating unit 12, the pressure that trigger head 131 is subjected to overcomes the support force that the triggering spring 132 that is positioned at trigger head 131 belows gives trigger head 131, and trigger head 131 falls to allowing beating unit 12 pass through and resets under the elastic force effect of triggering spring 132 by the back at beating unit 12.The pressure-air that is positioned at cylinder 9 promotes piston 10 motions, piston 10 is passed to beating unit 12 by the limiting section 122 of beating unit 12 with pressure, beating unit 12 high-speed motions are also beaten ailhead by tup 121, and the air energy that is positioned at cylinder 9 this moment discharges, and replys normal pressure.
Certainly, in the above-mentioned course of work, present embodiment can be preferably following structure carry out work: the position that flip flop equipment 13 is set cylinder 9 on the range of left side motion, after the air in the cylinder 9 is compressed to a certain degree, this pressure is difficult to overcome the barrier force of flip flop equipment 13 always, even be positioned at second operating position when push rod 7, air in the cylinder 9 are compressed near minimum volume and back-moving spring 25 under the extruding of inverted cam 61 during storage power, Pneumatic pipe cleaner is crossed the barrier force that thrust that piston 10 produces still is difficult to overcome flip flop equipment 13, since the position of flip flop equipment 13 be arranged on cylinder 9 on the range of left side motion, be difficult to overcome in the thrust that piston 10 produces under the situation of barrier force of flip flop equipment 13, direct extruding by cylinder 9 strokes makes the trigger head 131 on the flip flop equipment 13 be extruded, make trigger head 131 fall and make beating unit 12 current, the pressure-air that is positioned at cylinder 9 promotes piston 10 motions, piston 10 is passed to beating unit 12 by the limiting section 122 of beating unit 12 with pressure, beating unit 12 high-speed motions are also beaten ailhead by tup 121, the air energy that is positioned at cylinder 9 this moment discharges, and replys normal pressure.
And when push rod 7 by second operating position in the process of first operating position motion, inverted cam 61 resets under the effect of back-moving spring 25, and drive push rod 7 to direction moving linearly near driving cam 62, and then drive cylinder 9 to direction moving linearly near driving cam 62, cylinder 9 spurs beating units 12 integral body to the direction moving linearly near driving cam 62 by the hammer tail 123 that beating unit 12 embeds in it, and the limiting section 122 of beating unit 12 contacts with trigger head 131 once more and is spacing, be subjected to the continuous increase of pulling force in the subsequent process along with beating unit 12, the limiting section 122 of beating unit 12 pushes trigger head 131 once more, trigger head 131 falls to and triggers housing 133, and after the limiting section 122 of beating unit 12 passed through, trigger head 131 resetted under the effect that triggers spring 132 once more.Last inverted cam 61 contacts again with the inclined-plane of driving cam 62 and gets back to initial position under the effect of back-moving spring 25 elastic force, and at this moment, push rod 7 has been got back to first operating position once more, and back-moving spring 25 recovers original length.
By repeating above-mentioned steps, can realize that the tup 121 of beating unit 12 continues to impact the purpose of nail.
