Description
Technical field
The utility model relates to a kind of accurate little outer race unloading specific purpose tool that is used for.
Background technology
The unloading of accurate little outer race when assembling for microminiature motor (like small-sized gyro machine); To outer race be taken out very difficulty with traditional method of operating; And scratch the raceway of outer race easily, even cause scrapping of whole bearing, therefore be necessary to improve.
The utility model content
The technical problem that the utility model solves: a kind of specific purpose tool that is used for accurate little outer race unloading is provided, is mainly used in the unloading of the accurate little outer races of microminiature motor (for example bore diameter of outer ring is Φ 5) such as gyro machine.
The technical scheme that the utility model adopts: the specific purpose tool that is used for accurate little outer race unloading; Comprise pull bar; Said pull bar one end is a bullet, and its other end is shaped on the external screw thread I that screws with the nut I, and collet is sleeved on the pull bar; The first end of said spring clip be shaped on suitable taper hole of bullet and taper hole wall on be shaped on notch; Its other end is shaped on the external screw thread II that screws with the nut II, is set with axle sleeve on the said collet, and said axle sleeve is connected with pull bar through collet and can slides along pull bar.
Further, said taper hole front end is shaped on flange, is shaped on four notches on the said taper hole wall.
Further, said pull bar surface is shaped on groove, and said axle sleeve surface is shaped on slotted eye, and said collet surface is shaped on screwed hole, and screw passes behind slotted eye and the screwed hole its lower end successively and places in the groove and can slide along groove.
Further, said axle sleeve outer peripheral edges are shaped on anti-skidding line.
The utility model is compared with prior art simple in structure, is easy to make, and easy to operate, reliable operation has reduced scrapping of bearing, has improved efficient, can be widely applied in the assembling of microminiature motor, and unloading is free and relaxed than the outer race of minor diameter.

The specific embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1,2,3,4,5,6,7.
The specific purpose tool that is used for accurate little outer race unloading comprises pull bar 1, and said pull bar 1 one ends are bullet 7; Its other end is shaped on the external screw thread I 8 that screws with nut I 6, and collet 3 is sleeved on the pull bar 1, said collet 3 one ends be shaped on suitable taper hole 10 of bullet 7 and taper hole 10 walls on be shaped on four notches 12; Said taper hole 10 front ends are shaped on flange 13, and collet 3 other ends are shaped on the external screw thread II 11 that screws with nut II 5, are set with axle sleeve 2 on the said collet 3; Said axle sleeve 2 is connected with pull bar 1 through collet 3 and can slides along pull bar 1; Specifically, said pull bar 1 surface is shaped on groove 9, and said axle sleeve 2 surfaces are shaped on slotted eye 14; Said collet 3 surfaces are shaped on screwed hole 15, and screw 4 passes slotted eye 14 successively and afterwards places in the groove 9 and can slide along groove 9 in its lower ends with screwed hole 15.Axle sleeve 2 outer peripheral edges are shaped on anti-skidding line 16.
Method for using: when the unloading outer race, at first the rotating nut I 6, and pull bar 1 makes collet 3 be in the natural relaxation state under the effect of external screw thread I 8; The flange 13 of collet 3 front ends is put into the outer race endoporus, backward rotation nut I 6 then, pull bar 1 is post-tensioning under the effect of external screw thread I 8; Bullet 7 and taper hole 10 are oppositely moved, owing to be shaped on notch 12 on the collet 3, thus make collet 3 be in the spreading state; Make flange 13 edges of collet 3 catch on the edge of outer race; This moment, the rotating nut II 5, under the effect of external screw thread II 11, move behind the collet 3 outer race is taken out.Differ between general bearing bore diameter of outer ring and the stator hole and generally have only 0.3 ~ 0.4mm, and the end face of outer race and the distance between stator faces be usually between 0.4 ~ 0.5mm, so that the precision of the size of the flange 13 on the collet 3 should be suitable is higher.In addition because therefore the too small defective that causes insufficient rigidity of dimensional thickness of the flange 13 of collet 3 will consider that in manufacturing and designing process the end face of pull bar 1 when collet 3 spreadings is concordant with the end face of collet 3 to increase its rigidity.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
