Description
Technical field
The utility model relates to machine tool field, at length says it is a kind of automatic rotary grinding wheel bell-type dynamic/static piezoelectric main shaft.
Background technology
As everyone knows, the wheel guard that existing large vertical grinder electricity front-end of spindle is installed, all fixing through manual revolution, through being locked again behind the knockout screw rotary grinding wheel cover, this wheel guard inconvenient operation and can not be real reach numerical controlization.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of automatic rotary grinding wheel bell-type dynamic/static piezoelectric main shaft, and wheel guard can turn round automatically, thereby realizes the numerical controlization of grinding machine.
The utility model solves the technical scheme that its technical problem adopted: a kind of automatic rotary grinding wheel bell-type dynamic/static piezoelectric main shaft, comprise stator, rotor, rear bearing, fore bearing, thrust bearing, sleeve and main shaft, and main shaft one end is fixed with grinding wheel chuck; Be fixed with emery wheel on the grinding wheel chuck, emery wheel is equipped with wheel guard outward, it is characterized in that; Fixed cover and rotary sleeve are installed on the sleeve, and the rotary sleeve middle part is equipped with locking plate, and rotary sleeve top is fixed with Worm gear mechanism; Rotary sleeve bottom and wheel guard are fixed together; Worm screw and locking cylinder are installed on the fixed cover, and driven by servomotor is installed in the end of worm screw, the engagement of worm and wheel mechanism; The end face of locking plate is evenly equipped with locking hole, and the position of locking hole is corresponding with the expansion link of locking cylinder.
The beneficial effect of the utility model is that the realization wheel guard rotates automatically, fixes wheel guard through locking cylinder locking locking plate when being turned back to the angle that needs, and can realize the numerically controlled automatic of grinding machine spindle, increases work efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. rear bearings among the figure, 2. stator, 3. rotor, 4. sleeve, 5. fore bearing, 6. thrust bearing, 7. grinding wheel chuck; 8. wheel guard, 9. emery wheel, 10. protecgulum, 11. rotary sleeves, 12. needle rollers, 13. locking plates; 14. expansion link, 15. locking cylinders, 16. worm screws, 17. servomotors, 18. fixed covers, 19. main shafts.
The specific embodiment
Shown in Figure 1, the utility model main shaft 19 is installed in the sleeve 4 through rear bearing 1, fore bearing 5, and rotor 3 and stator 2 also are installed between main shaft 19 and the sleeve 4; Main shaft 19 1 ends are fixed with grinding wheel chuck 7, are fixed with emery wheel 9 on the grinding wheel chuck 7, the emery wheel 9 outer wheel guards 8 that are equipped with; Fixed cover 18 and rotary sleeve 11 are installed on the sleeve 4, and rotary sleeve 11 middle parts are equipped with locking plate 13, and rotary sleeve 11 tops are fixed with Worm gear mechanism; Rotary sleeve 11 bottoms and wheel guard 8 are fixed together, and worm screw 16 and two locking cylinders 15 are installed on the fixed cover 18, and the end of worm screw 16 is installed servomotor 17 and driven; Worm screw 16 and Worm gear mechanism engagement, the end face of locking plate 13 is evenly equipped with locking hole, and the position of locking hole is corresponding with the expansion link 14 of locking cylinder 15; Be set with thrust bearing 6 on the main shaft 19 of fore bearing 5 front ends; Thrust bearing 6 front portions are fixed with protecgulum 10, and protecgulum 10 can prevent that rotary sleeve 11 from moving axially, and between rotary sleeve 11 and fore bearing 5, the thrust bearing 6 needle roller 12 is installed.
But the utility model servomotor 17 is done 360 degree rotations through worm screw 16 driven rotary cover 11, and protecgulum 10 can prevent that rotary sleeve 11 from moving axially, and wheel guard 8 is connected as a single entity with rotary sleeve 11; Can be with rotary sleeve 11 rotation, wheel guard 8 main effects are to hurt sb.'s feelings and damage equipment in order to prevent that emery wheel 9 from splashing when damaged, locking plate 13 is locking devices of wheel guard 8 with expansion link 14; Locking plate 13 has a large amount of locating holes along circumference; Locking cylinder 15 is made up of dish spring and hydraulic cylinder, and the elastic force of dish spring compresses expansion link 14 and locking plate 13 when being in locking state, when being in releasing orientation in the expansion link 14 retraction locking cylinders 15; Wheel guard 8 is just rotatable; Unclamp through system's control locking cylinder 15,17 rotations of control servomotor are through 11 rotations of worm-and-wheel gear driven rotary cover; Thereby realize that wheel guard 8 rotates automatically, be turned back to that expansion link 14, locking plate 13 and the rotary sleeve 11 through locking cylinder 15 fixes wheel guard 8 when needing angle.
