Description
Affiliated technical field:
The utility model relates to handheld tool, is a kind of hand-held pneumatic tool, specifically, is a kind of pneumatic chipping hammer of hand-held.
Background technology:
The pneumatic basis of hand-held has purposes very widely as pneumatic chipping hammer etc.Existing pneumatic chipping hammer class pneumatic tool has cylinder, and piston is housed in the cylinder, relies on compressed air as power source, though easy to operate, because the air guide and the structure of giving vent to anger that adopt are reasonable inadequately, volume is big, structurally still comparatively complicated, reliability is bad, fragile easy-maintaining not again.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, reliable operation, noise pneumatic chipping hammer low, fragile, not easy to maintenance.
Technical solution of the present utility model is: a kind of pneumatic chipping hammer, main body is arranged, cylinder is arranged in the main body, piston is housed in the cylinder, it is characterized in that: inlet suction port and switch are housed at the rear portion of main body, the protecgulum of taking pore out of is housed in the front portion of main body, protecgulum also is equipped with the shovel head, has air flue between cylinder back segment and main body, has airtube in the piston, the open rearward end of airtube communicates with the cylinder rear cavity, and the front opening of airtube communicates with the cylinder front cavity.
Inlet suction port that be equipped with at the rear portion of the main body described in the utility model and switch are positioned on the blind nut of back, and there is intake valve in the INO Intake Open Central Shanxi Plain, and switch shaft is housed in the intake valve, and main body is equipped with the switch knob that contacts with switch shaft outward.A plug screw that is loaded on the main body is arranged in the intake valve, the seal head that is loaded on the air intake duct is arranged in the plug screw, between seal head and plug screw inwall spring is housed, seal head and switch shaft connect as one.Buffering is equipped with silently in the rear end of the cylinder in the main body, and the front end of cylinder is equipped with three-flute return air cover.The diameter of the back segment of cylinder inner cavity is bigger than leading portion, and correspondingly: the diameter of the piston in the cylinder also is pre-small post-large.The front end of the air flue that has between cylinder back segment and main body is connected with intake interface, and the open rearward end of air flue is in the middle part of cylinder.The airtube that has in the piston is "T"-shaped, and the back middle part in piston is opened in the rear end, and front end has two openings, lays respectively on the front side wall of piston.
The beneficial effects of the utility model are: simple in structure, reliable operation, active force is big, noise is low, volume is little, easy to use, not fragile, maintenance rate is low.Be specially adapted to the elimination that the welding generation is splashed in the shipbuilding, reach the purpose that prolongs Life of Ship.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings:
Accompanying drawing is the structural representation of a kind of pneumatic chipping hammer of the present utility model.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model.In this embodiment, main body 1 is arranged, cylinder 2 is arranged in the main body 1, piston 3 is housed in the cylinder 2, inlet suction port 4 and air inlet switch are housed at the rear portion of main body 1, the protecgulum 5 of taking pore out of is housed in the front portion of main body 1, protecgulum 5 also is equipped with shovel 6, and 1 of cylinder 2 back segments and main body have air flue 7, have airtube 8 in the piston 3, the open rearward end of airtube 8 communicates with cylinder 2 rear cavity, and the front opening of airtube 8 communicates with cylinder 2 front cavity.Inlet suction port 4 that be equipped with at the rear portion of described main body 1 and INO Intake Open close and are positioned on the blind nut 9 of back, there is intake valve in the INO Intake Open Central Shanxi Plain, switch shaft 10 is housed in the intake valve, the main body 1 outer switch knob 11 that contacts with switch shaft 10 that is equipped with, spanner 11 utilizes pin 17 to be loaded on the main body 1.A plug screw 12 that is loaded on the main body 1 is arranged in the intake valve, the seal head 13 that is loaded on the air intake duct is arranged in the plug screw 12, between seal head 13 and plug screw 12 inwalls spring 14 is housed, seal head 13 connects as one with switch shaft 10.Buffering silently (comprise silently 15 and rubber silently 16) is equipped with in the rear end of the cylinder 2 in the main body 1, and the front end of cylinder 2 is equipped with three-flute return air cover 18.The diameter of the back segment of cylinder 2 inner chambers is bigger than leading portion, and correspondingly: the diameter of the piston 3 in the cylinder 2 also is pre-small post-large.The front end of 1 air flue that has 7 of cylinder 2 back segments and main body is connected with intake interface 4, the middle part of the open rearward end of air flue 7 in cylinder 2.The airtube 8 that has in the piston 3 is for "T"-shaped, and the back middle part in piston 3 is opened in the rear end, and front end has two openings, lays respectively on the front side wall of piston 3.
