The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of impact-type pneumatic hammer as shown in Figure 1, comprise body 1, be located at the upper cover 2 on body 1 top, be located at the mounting flange 3 of body 1 bottom, in described upper cover 2, be provided with unidirectional valve pocket 6, in body 1, be provided with the air duct 4 and the air that are communicated with unidirectional valve pocket 6 respectively and hold old place 5, described upper cover 2 is provided with the air inlet 7 being communicated with described unidirectional valve pocket 6, the setting corresponding to air duct 4 of described air inlet 7, on described upper cover 2, be also provided with some serial interfaces 8, described some serial interfaces 8 hold old place 5 with described air respectively and are communicated with, in described unidirectional valve pocket 6, be provided with air inlet and seal up a door 9, described air inlet is sealed up a door and 9 is located between air inlet 7 and air duct 4, in described body 1, be also provided with the piston corresponding with air duct 4 10, between described piston 10 bottoms and body 1, be provided with back-moving spring 11, described body 1 lower right side is provided with exhaust outlet 12.
The above forms agent structure of the present utility model.
Operation principle of the present utility model is: when single the utility model work, seal described some serial interfaces 8, to air inlet 7, pour compressed air, compressed air enters after unidirectional valve pocket 6, promoting air inlet seals up a door and 9 moves down and occluded air passage 4, now compressed air forces air inlet to be sealed up a door 9 to tighten up, and air holds old place 5 and is communicated with air inlet 7, and compressed air enters air to be held in old place 5; When stopping pouring compressed air to air inlet 7, air holds Compressed Gas in old place 5 to be sealed up a door on 9 air inlet to move and seal air inlet 7, now air holds old place 5 and is communicated with air duct 4, compressed air enters in air duct 4, and promote piston 10 motions, complete and clash into action, compressed air is finally discharged from exhaust outlet 12, after shock completes, piston 10 is homing under the effect of back-moving spring 11.
When some the utility model tandem workings, by conduit, successively adjacent serial interface 8 previous of the present utility model is connected with a rear air inlet 7 of the present utility model, to first air inlet 7 of the present utility model being cascaded, pour compressed air, because holding old place 5, serial interface 8 and air be communicated with, compressed air can circulate by conduit in some the utility model, both convenient control also saved compressed air simultaneously, reduced and controlled cost.
Described air duct 4 is fixed in described body 1 by jump ring 13, easy for installation.The quantity of described some serial interfaces 8 is two, and described two serial interface 8 symmetries are positioned at the both sides of described air inlet 7.The described air inlet 9 employing elastomeric materials of sealing up a door are made, air inlet seal up a door 9 be shaped as " W " shape, not only play the effect of check valve, and sealing effectiveness is better.Described body 1 left side is provided with safe hanging hole 14, in order to prevent that the utility model from falling when working.Described piston 10 bottoms are provided with cushion pad 15, and cushion pad 15 is set, and have avoided piston 10 directly to clash into body 1, have extended service life of the present utility model, the noise while having reduced the utility model work.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
