Description
Technical field
The utility model belongs to pneumatic tool technical field, and refering in particular to one kind has valve type impactor.
Background technology
Wind pressure impactor used at present, outer tube and cylinder form interior outer shell, and valve actuating mechanism carries valve block, passes through
Gas chamber before and after the compressed air of drilling rod feeding impactor is alternately sent to piston respectively by valve block displacement, makes reciprocating motion of the pistons
Bore bit is impacted, impact energy is imposed on into rock.It is traditional that have that low wind pressure impactor in valve type uses is all that valve seat end face is flat,
Valve block beveling, valve block radial rotary, needs to be plugged in valve block upper limit with positioning pin bias in order to prevent.This structure,
Valve block can generate very big shearing force in high speed swinging to positioning pin, once positioning pin fracture failure, valve block because that cannot position,
Valve block inclined-plane can not effectively be contacted with valve seat air distribution hole, just can not work normally.
Utility model content
The purpose of this utility model, which is to provide one kind, valve type impactor, using flat valve chip architecture, and by valve seat air admission hole
Place setting inclined-plane so that valve block need not position finger setting, and structure is simpler, and work is more reliable.
What the purpose of this utility model was realized in：One kind has valve type impactor, including outer tube, is equipped in outer tube
Cylinder, the interior sliding of cylinder are connected with piston, and cylinder upper end is combined with valve seat and forms upper chamber, and cylinder lower end is combined with guide sleeve
And lower chamber is formed, the air flue toward lower chamber gas transmission is formed between cylinder and outer tube；Valve seat is equipped with and is respectively communicated with upper chamber
Enterprising stomata the lower air admission hole of lower chamber is connected with by air flue, the valve seat outer end face is arranged with inclined surface, upper air
Pore size distribution is distributed in another lateral incline in a lateral incline, lower air admission hole；Valve seat top end surface is covered with two kinds of stomatas of control
The valve block of break-make, valve block bottom surface are burnishing surface.
Preferably, the guide sleeve is equipped with the pilot hole that coordinates with piston spindle nose, and the upper surface of guide sleeve is towards piston
The shaft shoulder, and offer the air discharge duct for discharging high pressure gas between guide sleeve upper surface and the piston shaft shoulder.
Preferably, the air discharge duct is U-type groove, several are circumferentially evenly equipped in guide sleeve upper surface.
Preferably, valve deck is provided at the top of the valve block, valve block is limited between valve seat and valve deck；It is combined at the top of valve deck
Towards the check (non-return) valve of rear joint, check (non-return) valve caudal action has spring.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
The 1st, ramp structure on valve seat is set, conjugated using flat valve piece, eliminates locating pin structure, and even if valve block
The contact surface of rotation, valve block and valve seat is effective always.
When lifting impactor strong aperture blowing bottom when the 2nd, operating, piston shoulder can be finally fallen on guide sleeve, due to this
Process is high speed, and the gas between guide sleeve and piston shoulder has little time to disperse, and will generate high pressure air cushion, piston back
Top, so falls and pushes up up, produce a complete impact process, belongs to empty and beats phenomenon, guide sleeve can be broken；This
Scheme increases the high pressure gas velocity of discharge in the several U-lags of guide sleeve upper end surface milling, even if quickly lifting impactor,
Due to eliminating high pressure air cushion, piston is fallen will not spring back in guide sleeve top surface.
