In order to prevent damping draw-bar 2031 from walking, after adjustment, tighten stroke fastening screw nut 2044 again.
When beginning to use, activate switch, the first air inlet/outlet 2013 air inlet, the second air inlet/outlet 2014 is vented, zone of pressure
In dynamic air cylinder piston 202 and gag lever post, blind nut 2042 travels forward, and in cylinder piston 202 and gag lever post, blind nut 2042 then drives resistance
The 2044th, Buddhist nun's outer tube the 2032nd, damping draw-bar the 2031st, stroke adjustment nut the 2043rd, stroke fastening screw nut regulates fixing blind nut 2045 and
Idle stroke stop collar 2041 quickly moves forward together.
When the fixing blind nut 2045 of regulation encounters idle stroke adjustment cushion block 2046, blind nut the 2042nd, damping draw-bar in gag lever post
2031st, the 2044th, stroke adjustment nut the 2043rd, stroke fastening screw nut regulates fixing blind nut 2045 and idle stroke stop collar 2041 then stops
Only travelling forward, meanwhile, electric machine assembly 1 starts, and drives sleeve body 104 to rotate by rotor core 103, sleeve body 104
Drive interior axle 105 synchronous axial system 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, enter boring or tapping operating mode stroke, because damping draw-bar 2031 and damping are lived during operating mode stroke
Plug 2033 remains stationary as, and the inclined oil hole of air 20332 causing the hydraulic oil of rear chamber to be forced through on damping piston 2033 enters buffering
Grease chamber 20331, then enters front cavity by little oilhole 20334；Spring 2035 is oppressed steel ball 2036 and is withstood big oilhole
20333, because hydraulic oil flow is to consistent with spring 2035 elastic force direction, big oilhole 20333 is closed all the time, does not pass through liquid
Force feed；Owing to the aperture of little oilhole 20334 sets less, hydraulic oil Negotiation speed is relatively slow, before slow down damping outer tube 2032
Line speed, damping cylinder enters the hydraulic damping state of impulse stroke.Because, in damping outer tube 2032 movement forward, ante-chamber can
The volume accommodating hydraulic oil can accommodate the volume of hydraulic oil more than back cavity, and during movement, the pressure of back cavity is gradually reduced,
Float grease seal 2034 then moves forward to adapt to the change of rear cavity pressure.
Because damping oil hole size is constant, pre-adjust regulation valve union A 2015 and regulation valve union B 2016 row of being adjustable into
The size of pore, controllable intake and exhaust amount size in the unit interval for the cylinder, make damping outer tube 2032 overcome damping when moving ahead
Power becomes soon or slow can i.e. reach to adjust the purpose of 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 first air inlet/outlet 2013 give vent to anger, and the second air inlet/outlet 2014 enters
Gas, zone of pressure dynamic air cylinder piston 202 is moved rearwards by, and cylinder piston 202 carries dynamic damping outer tube 2032 and interior axle 105 rearward movement,
Hydraulic oil pressurized in ante-chamber body enters buffering grease chamber 20331 from little oilhole 20334, and hydraulic oil enters big oilhole 20333 simultaneously
Overcome the elastic force of spring 2035 and the gravity of steel ball 2036 to back down 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, owing to big oilhole 20333 and little oilhole 20334 enter simultaneously
Oil, so the speed of backhaul is fast, float grease seal 2034 is also identical with principle during forward movement, self-return backward.Work as cylinder
In the rear end face of piston then drives gag lever post when encountering blind nut 2042 front end face in gag lever post, blind nut 2042 is moved rearwards by together, limit
Position in blind nut 2042 then drives damping draw-bar the 2031st, stroke adjustment nut the 2043rd, stroke fastening screw nut the 2044th, regulate fix blind nut
2045 are quickly moved rearwards by together with idle stroke stop collar 2041, when the magnetosphere 2021 on cylinder piston 202 moves forward to magnetic
During the position that inductive proximity switch 1 can sense, return-stroke terminates, and air inlet stops, and electric machine assembly 1 stops operating, and one
The individual cycle of operation terminates, and waits and enters the next cycle of operation.
Technical scheme is simply explained in detail by above-mentioned detailed description of the invention, the present invention not only only office
Being limited to above-described embodiment, any of every foundation principle of the invention improves or replaces, all should be within protection scope of the present invention.
