The specific embodiment
Consult Fig. 1-Fig. 6.In a described most preferred embodiment, described Pneumatic reciprocating saw has one with the handle 1 of valve and press button, is assemblied in the air-flow pressurized strut 4 in shell body 5 cylindrical shells and the end cap 2 that links with air-flow pressurized strut 4.End cap 2 is built-in with air-flow supercharging lid 16 shown in Figure 3, be shaped with the axial flow hole 17 that is evenly distributed on the circumference anchor ring on the end face of air-flow supercharging lid 16, these 17 oblique angles, axial flow hole are according to the Lavalle principle, symmetrically towards the center axioversion, the uniform axioversion circular hole of this five equilibrium is consistent with direction on air-flow pressurized strut 4 end faces that the lower end links to each other, shape is consistent, the gas channel 15 that quantity is identical misplaces or communicates, when axial flow hole 17 communicates with gas channel 15, air-flow tilts to connect through described air-flow pressurized strut 4 bottom annular grooves vertically, form take offence the upwards pressurized air stream of lever 6 of one reverse push, it is more concentrated that the Lavalle pressurized air stream that produces enters air-flow pressurized strut 4 bottom annular grooves, and impulsive force is more arranged.
The linings 3 of air-flow supercharging lid 16 by the lower end link to each other such as Fig. 4, air-flow pressurized strut 4 shown in Figure 5, and are force-fitted in by bearing 8 in the cylindrical shell of shell body 5.Air-flow pressurized strut 4 connects air-leg 6 by adapter sleeve 9.Air-leg 6 is press fit relation with adapter sleeve 9.Adapter sleeve 9 be shaped with one can with the holddown groove (not shown) of width and the consistency of thickness of Saw blade 12, Saw blade 12 is fixed on the adapter sleeve 9 by the trip bolt on the adapter sleeve 9 by described holddown groove.Saw blade 12 both sides are provided with the positioning guide wheel 11 of 2 positions saw tooth bar 12 vertical direction, and Saw blade 12 stretches out the guide table of support 10 lower ends by two positioning guide wheels 11 on two horizontal connecting axles of support 10 die cavities, does straight reciprocating motion.
Be provided with a spring 13 that is assemblied on support 10 biside plates among Fig. 2, elasticity by spring 13 is received or the active force of contracting can guarantee the appropriate clearance amount of guide wheel and Saw blade 12, also can be according to the thickness of Saw blade 12, the coupling mechanism force of the screw of adjusting pole 10 both sides is located at the intermediate space of positioning guide wheel 11 of Saw blade 12 both sides and the thickness of Saw blade 12 and is consistent.The benefit of spring 13 is and can appropriateness adjusts free clearance, makes things convenient for manyly than shimming, also can be according to the thickness rapid adjustment gap of Saw blade 12.Simultaneously, during Saw blade 12 work, because the elastic acting force of spring 13 can guarantee that more Saw blade 12 is constant with the positioning guide wheel gap when vibration.
Be shaped with the axioversion gas flow hole passage 15 of the perforation bottom annular groove that arranges according to the Lavalle principle at air-flow pressurized strut 4 end faces shown in Figure 5, this gas channel 15 air-flow pressurized strut 4 cylinders that are periphery, towards central axis, form a rounding frustum around central axis and shrink the rotary body profile symmetrically.The incline direction in the axial flow hole 17 on the distribution of gas channel 15 and the said flow supercharging lid 16 is identical, but the angle that tilts can be variant, shape size is basically identical, quantity is identical, and is to concern one to one.Root at 4 three sinking stepped holes of air-flow pressurized strut is shaped with respectively annular groove, be shaped with the inclination airflow hole 14 of the uniform circumference of five equilibrium on the annular groove, this inclination airflow hole 14 tilts to connect said flow passage 15 vertically, make air-flow enter the pneumatic chamber of air-flow pressurized strut 4 according to the principle supercharging of aerodynamics Lavalle, assistive drive air-leg 6 moves upward.When 6 of air-legs move to pressurized strut 4 middle part, give certain high pressure draught impulsive force that makes progress, the opposition of generation drives air-leg 6 and moves upward, and makes 6 one-tenth certain cycles of its air-leg make progress lower reciprocating motion.Can also be shaped with the perforation cylinder lumen at air-flow pressurized strut 4 middle parts, the radial air flow hole that communicates with at least one gas channel 15 simultaneously moves upward during by this radial air flow hole with assisted gas lever 6.Be shaped with the vibration-damping sheet 7 that assisted gas lever 6 elasticity make progress in the bottom of air-flow pressurized strut 4 pneumatic chambers.
Operation principle of the present invention is, high pressure draught enters end cap 2 by handle 1, impact supercharging lid 16 and produce High Rotation Speed, when supercharging cover axial flow hole 17 on 16 end faces rotate to air-flow pressurized strut 4 on gas channel 15 sequence the time, the air-flow that enters gas channel 15 is blocked, enter supercharging and cover the upper surface that 16 axial flow holes, 17 interior air-flows directly impact air-leg 6, drive air-leg 6 and produce the active force that moves downward.Air-leg 6 moves downward arrival air-flow pressurized strut 4 bottom annular grooves and divides into the vibration-damping sheet 7 of putting, the elastic damping sheet 7 that bump is made by vulcanie, make vibration-damping sheet 7 produce reaction force upwards, assisted gas lever 6 moves upward, at this moment the axial flow hole 17 on the supercharging lid 16 rotates to when consistent with the gas channel 15 of pressurized strut 4, the air-flow that enters gas channel 15 arrives the bottom of pressurized strut 4, impact pressurized strut 4 bottom end faces, produce the air-flow that upwards impacts air-leg 6 bottom end faces, driving air-leg 6 moves upward, when the air stream drives air-leg 6 that makes progress is crossed inclination airflow hole 14, enter the air-flow of oblique airflow hole 14, the active force of making progress for air-leg 6 again promotes air-leg 6 and moves upward.It is reciprocating to drive again and again air-leg 6, drives on the Saw blade 12, and lower coming and going done the vertical line motion, and workpiece is implemented sawing processing.Because air-flow pressurized strut 4 inner chambers and air-leg 6 gaps are very little, have bearing 8 to locate in addition, make its air-leg 6 can only be on air-flow pressurized strut 4 interior works, lower round rectilinear motion.
