Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following enforcementExample, and coordinate accompanying drawing to be described in detail as follows:
It should be noted that, unless otherwise clearly defined and limited, term " first ", " second "Deng not representing order installation, do not represent the importance of described parts yet.
Refer to Fig. 1-Fig. 7, the fixture of machining large worm gear part, comprise chuck body 1, adjusting pad 2,Round bottom seat 9 and prevent that part to be processed from adding the round clamp 4 of play in man-hour, bolt special 6, described fixture thisBody is the cylinder that is shaped with centre bore, cylinder top be shaped with match with adjusting pad 2 first on baseAccurate face 1-1 and diameter are less than the 1-2 of projection portion of cylinder diameter, are shaped with it and are linked as in cylinder bottomThe circular bosses 1-4 of one, is shaped with datum level 1-3, described cylinder excircle first time in circular bosses bottomBetween limit and circular bosses, be evenly equipped with gusset 1-5.
In the present embodiment, described projection portion outside is shaped with and places outside the benchmark that part to be processed matchesCircle 1-2-1, centre is shaped with the hole concentric with cylinder centre bore.
In the present embodiment, described chuck body first on datum level and first time datum level for being parallel to each otherFace, its parallelism error value is less than 0.008mm.
In the present embodiment, datum level on the center line of described benchmark cylindrical and first, first time datum level are equalMutually vertical, its error of perpendicularity value is all less than 0.008mm.
In the present embodiment, described adjusting pad 2 upper ends be provided with match with part to be processed second on benchmarkFace 2-1, lower end is provided with the second time datum level 2-2 matching with datum level in chuck body first, described inOn second, datum level and second time datum level are the face of being parallel to each other, and its parallelism error value is less than 0.008mm.
In the present embodiment, described round bottom seat 9 upper ends are provided with matches with first time datum level of chuck bodyDatum level 9-1 on the 3rd, is provided with in round bottom seat bottom the 3rd time benchmark matching with machining tool workbenchFace 9-2, datum level and the 3rd time datum level are the face of being parallel to each other on the described the 3rd, its parallelism error value is littleIn 0.005mm.
In the present embodiment, uniform six the outer six side's screws 7 in described fixture lower end, six packing rings 8.
Operation principle of the present utility model is:
Refer to Fig. 2-Fig. 7, first the 3rd time datum level 9-2 of round bottom seat 9 is placed on to machining tool workDo on platform 10, then first time datum level 1-3 of chuck body 1 is placed on round bottom seat 9 the 3rd onDatum level 9-1 is upper, packs bolt special 6 into, and chuck body and round bottom seat are passed through to outer six side's screws 7, padCircle 8 tightens together, chuck body top (referring to Fig. 4) install successively adjusting pad 2, worm gear 3,Round clamp 4, carries out fasteningly with nut 5, then the 3-3 of machining worm wheel tooth portion is to final size. Due to this folderBenchmark on datum level 1-1 on first time datum level 1-3 of tool and first, second time datum level 2-2 and secondFace 2-1 is the face of being parallel to each other, and its parallelism error value is all less than 0.008mm, the 3rd time datum level 9-2With the 3rd on datum level 9-1 be also the face of being parallel to each other, its parallelism error value is less than 0.005mm, each upper,Lower datum level flatness error value is all less than 0.01mm, and benchmark cylindrical 1-2 center line and first time baseAccurate face is mutually vertical, and its error of perpendicularity value is less than 0.008mm, and this has just ensured the each datum level of this fixtureBetween uniformity and the uniformity between datum hole and datum level, the accumulated error value of fixture itself is fallenTo minimum, thereby ensure the precision of whole fixture. Simultaneously again due to worm gear 3 the 4th on datum level 3-1With the 4th time datum level 3-5 be also the face of being parallel to each other, its parallelism error value is less than 0.01mm, worm gear baseThe fit clearance error amount of accurate hole 3-2 and chuck body benchmark cylindrical is controlled within the scope of 0～0.005mm,The uniformity that this has just ensured worm gear and fixture, makes that accumulated error value between worm gear and fixture is same also fallsTo minimum, thereby make the 3-3 of worm-gear toothing portion processing meet drawing requirement.
