When beginning to use, starting switch, the air inlet of the first air inlet/outlet 2013, the second air inlet/outlet 2014 is vented, zone of pressure
Blind nut 2042 travels forward in dynamic cylinder piston 202 and gag lever post, and blind nut 2042 then drives resistance in cylinder piston 202 and gag lever post
Buddhist nun's outer tube 2032, damping draw-bar 2031, stroke adjustment nut 2043, stroke fastening screw nut 2044, the fixed and of blind nut 2045 of regulation
Idle stroke stop collar 2041 is quick together to be moved forward.
When the fixed blind nut 2045 of regulation encounters idle stroke adjustment cushion block 2046, blind nut 2042, damping draw-bar in gag lever post
2031st, stroke adjustment nut 2043, stroke fastening screw nut 2044, the fixed blind nut 2045 of regulation and idle stroke stop collar 2041 then stop
Only travel forward, at the same time, electric machine assembly 1 starts, and drives sleeve body 104 to rotate by rotor core 103, sleeve body 104
The synchronous axial system of interior axle 105 is driven by guide pin 106.Under the influence of air pressure, cylinder piston 202 continues band dynamic damping outer tube
2032 and interior axle 105 move forward, into drilling or tapping operating mode stroke, during because of operating mode stroke damping draw-bar 2031 and damping live
Plug 2033 remains stationary as, and the inclined oil hole of air 20332 for causing the hydraulic oil of rear chamber to be forced through on damping piston 2033 enters buffering
Grease chamber 20331, front cavity is then entered by small oilhole 20334；Spring 2035 oppresses steel ball 2036 and withstands big oilhole
20333, because hydraulic oil flow direction is consistent with the elastic force direction of spring 2035, big oilhole 20333 is closed all the time, does not pass through liquid
Force feed；Because the aperture setting of small oilhole 20334 is smaller, hydraulic oil is slower by speed, before slow down damping outer tube 2032
Scanning frequency degree, damping cylinder enter the hydraulic damping state of impulse stroke.Because in the damping movement forward of outer tube 2032, ante-chamber can
The volume for accommodating hydraulic oil is more than the volume that back cavity can accommodate hydraulic oil, and during movement, the pressure of back cavity is gradually reduced,
Float grease seal 2034 is then moved forward to adapt to the change of rear cavity pressure.
Because damping oil hole size is constant, regulation valve union A 2015 and the rows of being adjustable into of regulation valve union B 2016 are pre-adjusted
The size of stomata, intake and exhaust amount size of the cylinder in the unit interval is can control, damping is overcome when damping outer tube 2032 is moved ahead
Power becomes can be soon or slow, that is, reaches the purpose of adjustment impulse stroke speed.When mobile, damping outer tube 2032 is with being stuck in pipe
Spacing back-up ring 2037 in the inner wall groove of hole moves ahead, so spacing back-up ring 2037 can limit the limit that damping outer tube 2032 moves down
Position.
When the magnetosphere 2021 on cylinder piston 202 moves forward to the position that magnetic induction proximity switch 2 2012 can sense
When, damping impulse stroke terminates, and now external control device makes the outlet of the first air inlet/outlet 2013, and the second air inlet/outlet 2014 enters
Gas, zone of pressure move cylinder piston 202 and are moved rearwards, and cylinder piston 202 moves backward with dynamic damping outer tube 2032 and interior axle 105,
Hydraulic oil in front cavity is pressurized enters buffering grease chamber 20331 from small oilhole 20334, while hydraulic oil enters big oilhole 20333
Overcome the elastic force of spring 2035 and the gravity top of steel ball 2036 to open steel ball, hence into buffering grease chamber 20331, buffer grease chamber
Hydraulic oil in 20331 then enters rear chamber by inclined oil hole of air 20332, because big oilhole 20333 and small oilhole 20334 enter simultaneously
Oil, so the speed of backhaul is fast, float grease seal 2034 is also identical with principle during forward movement, backward self-return.Work as cylinder
Then drive blind nut 2042 in gag lever post to be moved rearwards together when the rear end face of piston encounters 2042 front end face of blind nut in gag lever post, limit
Blind nut 2042 then drives damping draw-bar 2031, stroke adjustment nut 2043, stroke fastening screw nut 2044, the fixed spiral shell of regulation in the bar of position
Lid 2045 and idle stroke stop collar 2041 are quickly moved rearwards together, when the magnetosphere 2021 on cylinder piston 202 moves forward to
During the position that magnetic induction proximity switch 1 can sense, return-stroke terminates, and air inlet stops, and electric machine assembly 1 stops operating,
One cycle of operation terminates, and waits and enters next cycle of operation.
Simply technical scheme is explained in detail for above-mentioned embodiment, the present invention not only only office
It is limited to above-described embodiment, every any improvement or replacement according to the principle of the invention all should be within protection scope of the present invention.
