A kind of operation principle of the drill bit of the present invention from rotary type pneumatic down-hole hammer：
Refering to Fig. 4, the situation the location of when hitting drill bit 14 for piston 6 when (ultra-Left position).Dotted line represents piston
6, roller 9 slides in eight axial grooves 15 of drive sleeve 10.
Refering to Fig. 3 to Fig. 5, in stroke movement, roller 9 is since the ultra-Right position R shown in Fig. 4-b along A skewed slots 16
Motion, and then drive sleeve 10 is turned an angle along the direction shown in arrow.As 9 in-position Y of roller, drive sleeve 10
Just stop operating, and in roller 9 continues motion to ultra-Left position X, drive sleeve 10 remains stationary as.In drawback movement, rolling
Before 9 in-position Z of son contact skewed slot 16 again, drive sleeve 10 remains stationary as.Because the summit of A skewed slots 16 not with axial groove 15
Central alignment, so roller can not return to the A skewed slots 16 passed through during stroke, but enter B skewed slots 33.Roller 9 is along B skewed slots
33, which continue motion, forces drive sleeve 10 to remain unchanged along the same angle of the rotation of direction shown in arrow.Roller 9 enters and B skewed slots afterwards
The connected axial groove of 33 right-hand members simultaneously moves to ultra-Right position (above R), and drive sleeve 10 remains stationary as during this.
The rotation of described drill bit 14 is mainly to be realized by the stroke movement and drawback movement of piston 6, refering to figure
1, it may be seen that the motion of whole piston 6 is by top connection 1, non-return valve 2, distribution seat 4, inner casing 5, coordinate between piston 6
Carry out.
Refering to Fig. 2, for the backhaul initial period of piston 6, compressed air system air inlet hammer top connection 1 by the road, gas
The pressure of stream forces the spring 3 of non-return valve 2 to compress so as to push non-return valve 2 (valve element) open, via the air distribution hole 30 of distribution seat 4 and interior
The preceding air admission hole 21 of cylinder 5 enters preceding air chamber 19, the backhaul in the presence of pressure differential of piston 6, gas compression in rear gas chamber 24；Work as work
When the left side 20 for the sealing surface that plug 6 is held greatly contacts with inner casing 5, preceding air chamber 19 seals, and piston relies on the preceding gas expansion of air chamber 19
Do work and continue backhaul；When the right-hand member 23 for the sealing surface that piston 6 is held greatly departs from inner casing 5, the air inlet of rear gas chamber 24, now piston 6
Continue backhaul by inertia；When the stage casing of piston 6 departs from guide sleeve 7, the preceding gas of air chamber 19 drains into bottom hole by central through hole 18.
Piston 6 continues to slow down until being still in top dead centre, and backhaul terminates.
In the backhaul stage, piston 6 moves right, and due to the cooperation of the roller 9 on piston 6 and drive sleeve 10, makes drive sleeve
10 are rotated a certain angle, and drive sleeve 10 is coupled with drill bit 14 by spline, so as to drive drill bit 14 to rotate certain angle.
Refering to Fig. 3, for the stroke initial period of piston 6, compressed gas air admission hole 22 after distribution seat 4 and inner casing 5
Into rear gas chamber 24, piston 6 is promoted to start stroke to the left, the preceding gas of air chamber 19 drains into bottom hole by central through hole 18；Work as piston
When guide sleeve 7 is slipped into stage casing 26, preceding air chamber 19 seals, gas compression；As piston 6 continues stroke, when the big end right-hand member of piston
When face 23 contacts with inner casing 5, rear gas chamber 24 stops air inlet, and now piston 6 continues to rush by the gas expansion for doing work of rear gas chamber 24
Journey；When the big end left side 20 of piston departs from inner casing 5, the preceding air inlet of air chamber 19, piston 6 continues stroke by inertia；With work
Plug 6 continues stroke, and piston small end 25 impacts the afterbody of drill bit 14, and stroke terminates, and then starts next impact cycle.
In the stroke stage, the high speed of piston 6 moves downward, and due to the cooperation of the roller 9 on piston 6 and drive sleeve 10, makes biography
Dynamic set 10 is rotated a certain angle, and drive sleeve 10 is coupled with drill bit 14 by spline, so as to drive drill bit 14 to rotate certain angle
Degree.
