Five. the specific embodiment:
Embodiment one: referring to Fig. 1-Fig. 5, label 1 is an emery wheel among the figure, and 2 is Grinding wheel holder, and 3 is rotor, and 30 is that rotor of output shaft axle is terminal, and 31 are the locking section; 32 are the section of unclamping, and 4 is stator, and 5 is shell, and 6 is positioning sleeve, and 61 is flange, and 7 is the steel ball cover; 8 are the tension cover, and 9 is the taper seat of rotor of output shaft axle end, and 91 is Grinding wheel holder internal diameter circular cone side, and 10 is steel ball, and 11 is the dish spring, and 12 are tension cover nut; 13 is card, and 14 is rear bearing block, and 15 is back nut, and 16 is preceding tegillum, and 17 is the money nut; 18 is dust ring, and 19 is the gas dedusting, and 20 is cylinder body, and 21 is piston, and 22 is the cylinder body bonnet; 23 is inner water sleeve, and 24 is pull bar, and 25 is fixed stop, and 26 is compressing tablet, and 27 is annular preform.
A kind of Grinder Spindle of automatic replacing emery wheel comprises the electric main shaft of being made up of shell 5, stator 4 and rotor 5, and rotor of output shaft axle one end of electric main shaft is equipped with emery wheel mechanism, and emery wheel mechanism comprises emery wheel 1 and Grinding wheel holder 2.Stator 4 annulars are fixed on shell 5 madial walls, and between shell 5 and stator 4, are provided with annular inner water sleeve 23.Rotor 5 two ends are installed in the bearing block of shell through bearing respectively, also are provided with the preceding tegillum 16, the dust ring 18 gentle dedusting passages 19 that are used for sealed bearing.
(tubulose) rotor of output shaft axle 5 terminal lateral walls and Grinding wheel holder 2 internal diameter sidewalls are close-fitting taper seat structure, and referring to label 9 and 91, rotor of output shaft axle is rotated the drive Grinding wheel holder and rotated together.Simultaneously; On Grinding wheel holder 2 inner diameter holes of said emery wheel mechanism, be fixed with the positioning sleeve 6 of a concentric; This positioning sleeve is slightly less than its internal diameter away from electric main shaft one side near the internal diameter of electric main shaft one side, promptly on the internal diameter sidewall of this positioning sleeve, is provided with the step surface 61 that flange forms near electric main shaft one side.
Rotor of output shaft axle one end of electric main shaft is provided with steel ball harmomegathus mechanism; Steel ball harmomegathus mechanism in the present embodiment is that the tension cover outside is fixed with steel ball cover 7; Output 30 (rotor of output shaft axle) end portion of the armature spindle 5 of tubular is inserted in this steel ball cover 7; And be respectively equipped with adjacent but waney locking section 31 and the section of unclamping 32 on the output 30 of this armature spindle 5, wherein the section of unclamping 32 is positioned at the output shaft least significant end; On the lateral wall of said steel ball cover 7, be evenly equipped with a plurality of radial direction through hole and be separately installed with steel ball 10 (10 steel balls are for example arranged); Thereby making steel ball be positioned at the steel ball cover less than steel ball size, the radial direction through hole diameter only have spherical calotte can stretch out outside the radial direction through hole; Said each steel ball be positioned at when section locking stretch out respectively form outside the corresponding radial direction through hole with the steel ball ring of positioning sleeve than the large diameter coupling, said each steel ball makes the less internal diameter coupling of steel ball cover and positioning sleeve within the corresponding radial direction through hole of indentation respectively when being positioned at the section of unclamping.
Fig. 3 and Fig. 4 are respectively that steel ball is in spreading state and indentation state; The spreading state of Fig. 3 belongs to nature, and when cylinder promotes pull bar together when the emery wheel direction move, each steel ball 10 is driven by steel ball cover 7 and also rolls forward or slip; Thereby each steel ball 10 moves in the section of the unclamping automatic withdrawal in the 32 backs steel ball cover 7 from the locking section; Like Fig. 4, steel ball cover 7 can pass freely through in the positioning sleeve 6 of Grinding wheel holder internal diameter side, when being inserted into assigned address at this moment; The cylinder escape pipe is abandoned; Pull bar 24 resets under the effect of dish spring 11, and this moment, each steel ball 10 was in the spreading state again, because the outer margin contour diameter that forms behind each steel ball 10 spreading is greater than the step ledge 61 of positioning sleeve 6 rear ends.Said positioning sleeve 6 than being the arc surface transition between large diameter and the less internal diameter (step ledge).Behind each steel ball 10 location, the outside of the output 30 of electric main shaft output shaft 5 closely contacts with Grinding wheel holder 2 internal side diameter face cone faces, thereby the output shaft of whole electric main shaft 5 is fixed to one with Grinding wheel holder 2, can rotate synchronously, accomplishes automatically and installs.The automatic detach procedure of electricity main shaft and emery wheel mechanism is opposite with its autoinstall procedure, does not detail.
Embodiment two: accompanying drawing is not drawn; Content and embodiment one are basic identical; Something in common does not repeat: owing to be fixing matching relationship between the rotor of output shaft axle of electric main shaft and the Grinding wheel holder; So the cooperation between rotor of output shaft axle lateral surface and the Grinding wheel holder internal diameter side is not limited only to embodiment one described taper seat and cooperates or frustum of a cone fit structure, also can adopt the matching relationship of just polygon terrace with edge or just polygon frustum structure.
Embodiment three: accompanying drawing is not drawn, and content and embodiment one are basic identical, and something in common does not repeat: the shape that is fixed in positioning sleeve and the steel ball cover on the Grinding wheel holder internal diameter side is not limited only to circular matching relationship; Also can adopt the regular polygon structure; Adopt and steel ball number regular polygon structure always regular hexagon for example, octagon according to the quantity of steel ball; Regualr decagon, dodecagon etc.
Embodiment four: accompanying drawing is not drawn; Content and embodiment one are basic identical; Something in common does not repeat: the propelling of pull bar and the situation of withdrawal are not limited only to the matching relationship of embodiment one described employing cylinder and dish spring; Can also save the dish spring and only adopt cylinder or hydraulic cylinder, the piston rod and pull bar one end that are about to cylinder or hydraulic cylinder are fixed, the piston rod drive of stretching out or withdrawing and all leaning on cylinder or hydraulic cylinder of pull bar.
Embodiment five: accompanying drawing is not drawn; Content and embodiment one are basic identical; Something in common does not repeat: the push-pull mechanism that drives the pull bar motion is not limited only to cylinder or hydraulic cylinder, also can adopt the rack-and-pinion fit structure, perhaps the turbine and worm fit structure; Perhaps crank connecting link fit structure is perhaps realized the structures such as release or indentation of pull bar through the control eccentric rotational angle.
