There are two groups of orthogonal discouraged through-holes, the inboard wall of cylinder block to lose heart between through-hole and rapid aeration connector is provided with one group of limit convex
It rises, pulling plate pan bottom offers screw hole, and piston hammer is "convex" shaped structure, is movably arranged in cylinder body, in drawing disk and cylinder body
The stroke that is limited of retention bead in move back and forth, air flue is offered in the middle part of piston hammer.
Wherein, the air flue on piston hammer includes axial air flue and radial air flue, and axial air flue is along piston hammer bottom axial direction
It opens up, axial airway length is less than piston hammer axial length, and radial air flue is provided on axial air flue, and radial air flue runs through piston
Hammer is radial.
Preferably, drawing disk and cylinder body joint offer several annular grooves, are provided with sealing ring in annular groove.
Wherein, drawing disk and impact disc are equidistant fixed using annular using several hexagon socket cap head screws.
The utility model has the following beneficial effects:
1. the utility model is arranged by structure optimization, compressed air is connected to rapid aeration connector, with compressed air
It for power source, is cooperated by the discouraged duct of piston hammer air flue and cylinder body, realizes piston hammer in the intracorporal reciprocating motion of cylinder.
2. structure is simple, the detachable installation of all parts, easy to operate by the Pneumatic pin puller rationally designed, it is only necessary to
It controls compressed air air inlet and can be completed and once pull pin operation, and it is small to operate with space, is convenient for carrying operation.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model.
Fig. 2 is the overall structure figure of the utility model.
The side view of the position Fig. 3 the utility model.
Main component symbol description:
1: cylinder body, 2: lose heart through-hole, and 3: retention bead, 4: drawing disk, 5: screw hole, 6: annular groove, 7: sealing ring, 8: impact
Disk, 9: hexagonal cylindrical head screw, 10: piston hammer, 11: axial air flue, 12: radial air flue, 13: rapid aeration connector.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1-3, including cylinder body 1, drawing disk 4, impact disc the utility model discloses a kind of Pneumatic pin puller
8 and piston hammer 10, cylinder body 1 is tubular cylinder body, and the rear and front end of cylinder body 1 passes through several hexagon socket cap head screws 9 respectively and uses
Annular is equidistantly mounted with drawing disk 4 and impact disc 8, rapid aeration connector 13 is connected in the middle part of cylinder body 1, rapid aeration connects
Two groups of orthogonal discouraged through-holes 2 are offered on cylinder body 1 between first 13 and impact disc 8, the through-hole 2 that loses heart connects with rapid aeration
1 inner wall of cylinder body between first 13 is provided with one group of retention bead 3, and 4 bottom of pulling plate disk offers screw hole 5, and piston hammer 10 is " convex "
Character form structure is movably arranged in cylinder body 1, is carried out in the stroke that is limited of retention bead 3 of drawing disk 4 and cylinder body 1 reciprocal
Movement, the middle part of piston hammer 10 offers air flue.
Drawing disk 4 and 1 joint of cylinder body offer several annular grooves 6, are provided with sealing ring 7 in annular groove 6.
Air flue on piston hammer 10 includes axial air flue 11 and radial air flue 12, and axial air flue 11 is along 10 bottom of piston hammer
It axially opens up, axial 11 length of air flue is less than 10 axial length of piston hammer, and radial air flue 12 is provided on axial air flue 11, radial
Air flue 12 is radial through piston hammer 10.
Working principle:
The utility model is by Optimal Structure Designing, first with stud by straight pin to be extracted and Pneumatic pin puller
Drawing disk 4 screws, and compressed air pipe is connected with rapid aeration connector 13, opens compressed air valve, and compressed air is passed through
The air flue of piston hammer 10 is moved to 10 tail portion of piston hammer, and compressed air starts to lose heart in cylinder when close to impact disc 8, and piston hammer 10 leans on
Inertia continues preshoot, is repelled back after impact disk 8, impact disc 8 then drives drawing disk 4 to be pulled outwardly straight pin, anti-
It plays under inertia and 10 exocoel gas pressure of piston hammer, piston hammer 10, which is moved forwards, constitutes confined space with cylinder body 1, is formed flexible slow
Bed course is rushed, compressed air enters cylinder body 1 again at this time, again presses piston hammer 10 forward, and so on ballistic motion, and straight pin is not
Outside drawing disconnectedly, until being pulled out.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
