Abstract
The utility model provides a rotary file. The type relates to a work piece machining tool, especially relates to a rotary file. And the heat dissipation performance is good. Including file body and rigid connection head, file body with the inside liquid bag that is equipped with of rigid connection head, be equipped with at least a set of liquid outlet on the liquid bag, be equipped with out the liquid hole on file body, the liquid outlet with go out the liquid hole and pass through the pipeline intercommunication. Rotatory file high-speed rotation during in-service use gets rid of water to the liquid outlet, gives differential pressure valve a pressure, opens after exceeding the critical value of differential pressure valve, and water oozes from going out the liquid hole and cools down and prevents the overheated phenomenon of rotatory file, the life of extension rotatory file.
Description
Technical Field
The utility model relates to a work piece machining tool especially relates to a rotary file.
Background
Rotary files are common deburring tools used in machining workpieces. At present, the rotary file is widely used, for example, an engraving pen, a small handheld rotary file and the like, and due to the special application of the rotary file, the rotary file is driven by a flexible shaft or pneumatically. The common rotary file is mostly made of solid hard alloy and provided with a rigid shaft handle, the rotary file needs to rotate for a long time and rub with a workpiece to remove burrs on the surface of the workpiece when in use, and the rotary file is easy to overheat when in use for a long time, so that the reuse of the rotary file is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of prior art, the utility model provides a rotatory file that heat dispersion is good.
The utility model discloses a following technical scheme realizes: the utility model provides a rotary file, includes file body and rigid connection head, file body with the inside liquid bag that is equipped with of rigid connection head, be equipped with at least a set of liquid outlet on the liquid bag, be equipped with out the liquid hole on file body, the liquid outlet with go out the liquid hole and pass through the pipeline intercommunication.
The file is characterized in that a plurality of flow guide grooves are formed in the inner wall of the file body, the liquid outlet hole is formed in the flow guide grooves, and the liquid outlet is clamped on the flow guide grooves and communicated with the liquid outlet hole.
And a differential pressure valve is arranged on the liquid outlet.
The spiral direction of the guide groove is the same as that of the file teeth on the outer wall of the file body.
Compared with the prior art, the utility model discloses when rotatory file is rotatory, rivers play in the liquid bag under the effect of centrifugal force, and for the cooling of rotatory file, prevent the overheated phenomenon of rotatory file, the life of extension rotatory file. Rotatory file high-speed rotation during in-service use gets rid of water to the liquid outlet, gives differential pressure valve a pressure, opens after exceeding the critical value of differential pressure valve, and water oozes from going out the liquid hole and cools down and prevents the overheated phenomenon of rotatory file, the life of extension rotatory file.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a partial cross-sectional view of the present invention;
FIG. 3 is an enlarged view at A in FIG. 2;
in the figure: 1. a rigid connector; 2. filing; 3. filing teeth; 4. a liquid sac; 5. a pipeline; 6. a differential pressure valve; 7. and a diversion trench.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-3, a rotary file comprises a file body 2 and a rigid connector 1, wherein a liquid bag 4 is arranged inside the file body 2 and the rigid connector 1, at least one group of liquid outlets are arranged on the liquid bag 4, liquid outlet holes are arranged on the file body 2, and the liquid outlets are communicated with the liquid outlet holes through a pipeline 5. When the rotary file is rotated, water in the liquid bag 4 flows out under the action of centrifugal force, the rotary file is cooled, the phenomenon that the rotary file is overheated is prevented, and the service life of the rotary file is prolonged.
The inner wall of the file body 2 is provided with a plurality of diversion trenches 7, the liquid outlet hole is formed in the diversion trenches 7, and the liquid outlet is clamped on the diversion trenches 7 and communicated with the liquid outlet hole. And a differential pressure valve 6 is arranged on the liquid outlet. When the rotary file is rotated, water in the liquid bag 4 flows out under the action of centrifugal force, the rotary file is cooled, the phenomenon that the rotary file is overheated is prevented, and the service life of the rotary file is prolonged. Rotatory file is high-speed rotatory during in-service use, gets rid of water to the liquid outlet, gives differential pressure valve 6 pressure, opens after exceeding differential pressure valve 6's critical value, and water oozes from going out the liquid hole and cools down and prevent the overheated phenomenon of rotatory file, the life of extension rotatory file.
The guide groove 7 has the same rotation direction with the teeth 3 on the outer wall of the file body 2.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
