Detailed description of the invention
A kind of novelendoporus milling tool, this instrument comprises fixing 1 and grinding rod 6; Fix and be provided with cavity 1, be provided with enclosing cover 20 outside cavity, cavity is provided with air inlet pipe 2; Grinding rod 6 hollow, grinding rod 6 warp-wise surface uniform is distributed with the grinding rod utricule 7 expanded of more than three or three, on grinding rod utricule 7, extruding is equiped with grinding mill part 8, and grinding rod is provided with cleaning pore 9, and air inlet pipe 2 is connected with grinding rod 6 hollow by isocon 25; Grinding rod 6 and grinding rod utricule 7, cleaning pore 9 is connected with the air inlet pipe 2 of fixing handle with grinding rod hollow.Fixing in the structure of two air inlet pipe in rotation, grinding rod utricule 7 can be provided with helical structure equally.
Grinding rod 6 and grinding rod utricule 7 melt integrally to be connected to form grind and grind part stopper slot 10 and grind part limited step 11 and fix to grind with grinding and grind part 8.Grinding mill part 8 there is corresponding positioning step 26.Grinding mill part 8 basic structure is divided into two classes: class grinding shape mill part participates in means of abrasion with the convex surface of thin piece of hard lightweight (as working of plastics, aluminum component) and plates hard abrasive material; Class grinding shape mill part is contained in grinding rod utricule with cloth or paper and becomes the one side of convex surface participation means of abrasion to be stained with hard abrasive material (being similar to cloth tissue paper, paper twine paper), requires cannot there be hard abrasive material with grinding rod body interface face portion.
Fix and 1 one end is provided with flexible connecting rod 5, flexible connecting rod 5 is connected with grinding rod 6.Be provided with tracheae 4 and tracheae 12 in flexible connecting rod 5, the regulating block 15 that the other end of flexible connecting rod 5 is connected with U-shaped axle 14 by connecting rod 13 is connected, and curved 16 of U-shaped axle is connected with the piston 18 in cylinder 3 by connecting rod 17; The centre that U-shaped axle 14 is positioned at connecting rod 13 and U-shaped axle curved 16 fixed by support 19, the other end of U-shaped axle 14 is fixed on fixing on the housing of 1, and the point of adjustment above regulating block 15 is curved 16 equidirectional with U-shaped axle to the straight line of the central point of U-shaped axle turning cylinder at the central point of U-shaped axle curved 16.
Fixing being distributed with functional switch 21,22,23,24 on 1.Functional switch 21 is for default grinding operating air pressure, and regulating action is in the power of hole inwall; Functional switch 22 opens grinding work-piece rotating speed for setting; Functional switch 23 to stretch the frequency for setting and opening grinding work; With functional switch 24 for setting and opening grinding work cleaning throughput.
novelthe processing method of endoporus milling tool: grinding mill part is loaded in grinding mill part stopper slot and insert in the hole that will grind together with grinding rod utricule.Hold milling tool handle or be fixed on moveable support.Preset grinding operating air pressure, open rotation, unlatching is flexible, open gas cleaning, when grinding taper hole, cross section, hole corner angle, connecting rod 13 is connected with the point of adjustment above regulating block 15, the volume of flexible change grinding rod utricule is larger, regulate the distance of point just from the axle center that U-shaped axle rotates be connected less, can accomplish it is onesizely reach synchronous with the flexible frequency by the power keeping grinding rod utricule 6 to act on hole inwall in regulating guarantee grinding telescopic process, during grinding straight hole, the point of adjustment above connecting rod 13 and regulating block 15 be departed from movement relation.
The capacity convenient operation of gas can be reduced for grinding large diameter hole
Air enter into grinding rod utricule 6 can flow to make when the increase grinding rod utricule 7 periphery being uniformly distributed more than three or three can reach grinding mill part 8 of the strength extruding top loading of demand hollow.
Adopting the different grinding required to grind part can to different materials, different hardness, and the different endoporus required grinds.The method of positioning step is adopted to ensure the grinding mill position of part in grinding.Adopt is that the power of medium tightly pushes away grinding mill part and grinds with air.Adopt the thin foam and cooling that produce in air cleaning grinding.Adopt hard or make grinding rod utricule compared with the method that abrasive hardcoat rod utricule is combined with increase grinding rod utricule.Adopt hard or grind part compared with the grinding rod utricule of hard with fixing grinding of power that the stopper slot increased in the middle of grinding rod utricule and limited step are produced by air pressure and hole internal face effect.Adopt difform grinding rod utricule can grind difform endoporus.Adopt the method grinding taper hole, cross section, the hole rib that change pneumatophore volume size.This novelthe scope that endoporus milling tool can be suitable for is wide, extensively can be suitable at field of industrial production.
