Abstract
The utility model relates to the technical field of pneumatic grinding tools, and discloses an air micro grinder. The air micro grinder comprises an air inlet pipe, an energy conversion device, an air returning flue and a grinding head and further comprises an air returning block arranged above the grinding head. The air returning block comprises a first air flue and a second air flue, the first air flue faces the direction of the grinding head, the first air flue is not parallel to the second air flue, the air inlet pipe penetrates through the first air flue, and the air returning flue is communicated with the second air flue. Due to the fact that the air outlet direction of the air micro grinder is changed, the air outlet direction does not face the face of an operator, the operating process is safer, furthermore, burrs and the like produced during the grinding operation process are blown away through the air at the air outlet, the compressed air can be recycled, the splashing of the burrs is effectively avoided, the purpose of cleaning a workpiece is achieved, energy sources are saved, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of windmill pen, belongs to pneumatic milling tools technical field.
Background technology
Pneumatic grinding mill is to utilize compressed air the pressure energy of air to be converted to the rotating mechanical energy of grinding head, carries out the machinery that polishing to workpiece, deburring etc. are processed.Also claim Pneumatic grinding machine, some pneumatic grinding mills are made lip pencil, so custom is called windmill pen, are usually used in the operations such as deburring, engraving, polishing.
The air inlet of windmill pen is connected with compressed air hose, compressed air flows into energy converter device by air inlet pipe, pressure energy is converted to rotation function, thereby drive grinding head rotation to carry out polishing operation, through the compressed air of energy conversion device by return air inlet discharged to atmosphere, at present, the return air of windmill pen normally directly upwards blows out from a windmill afterbody, with grinding head opposite direction, in use procedure, the burr of polishing can disorderly fly, be easy to get on operator's body, and afterbody air-out is over against operator face, drive due to return air inlet moving air, make the burrs such as iron filings often fly to operator's face, abnormally dangerous.
Summary of the invention
For the shortcoming of an above-mentioned existing windmill return air, the purpose of this utility model is to provide a kind of windmill pen, can make the burr under the polishing of windmill pen disorderly not fly, and improves the security of operation, can also play the effect of cleaning workpiece simultaneously, has improved production efficiency.
Technical scheme: a kind of windmill pen, comprise air inlet pipe, energy conversion device, air-return duct, grinding head, also comprise return air piece, described return air piece is arranged on the top of described grinding head, and described return air piece comprises the first air channel and the second air channel, described the first air channel is towards grinding head direction, described the first air channel and described the second air channel are not parallel, and described air inlet pipe is through described the first air channel, and described air-return duct is connected with described the second air channel.
Compressed air flows to the second air channel of return air piece through air-return duct like this, because the second air channel has changed the direction that compressed air blows out, makes compressed air can directly not blow to operator's face, operation safe.
Best, described the first air channel is substantially vertical with described the second air channel, and the compressed air that flows to the second air channel by air-return duct like this blows out with regard to level, operation safe.
Further, be also provided with the 3rd air channel on described return air piece, described the 3rd air channel is communicated with described the second air channel, and described the 3rd air channel is towards described grinding head direction.Because the second air channel high-speed air flows out, make the 3rd air channel produce negative pressure, thereby when grinding head is polished, the burr of generation, iron filings etc. siphon away like this.
The end in the second air channel of described return air piece can also be provided with plug, because plug is blocked the outlet in the second air channel, the compressed air that air-return duct flows out is blown out by the 3rd air channel, and the burr iron filings that polishing can be produced etc. blow away downwards, play the effect of cleaning workpiece simultaneously.
Beneficial effect:
The utility model is by changing the direction of a windmill air-out, make air-out direction not towards operator face, safer, further, burr polishing operation being produced by the wind that utilizes air outlet etc. blows away, and compressed air is reused, effectively avoided splashing of burr, played the effect of cleaning workpiece simultaneously, saved the energy, and improved production efficiency.
