The specific embodiment
Fig. 1, Fig. 2, shown in Figure 3, main shaft 25 of the present invention is installed in the sleeve 11 through rear bearing 5, fore bearing 12, and rear bearing 5 front portions are provided with seal cover 7; Rotor 10 and stator 9 also are installed between main shaft 25 and the sleeve 11, are set with motor water jacket 8 outside the stator 9, main shaft 25 1 ends are fixed with grinding wheel chuck 14; Be fixed with emery wheel 16 on the grinding wheel chuck 14, through rotary sleeve 24 wheel guard 15 be installed outside the emery wheel 16, protecgulum 23 and thrust bearing 13 are installed on the main shaft 25 between grinding wheel chuck 14 and the fore bearing 12 successively; Main shaft 25 inner chambers are equipped with broaching tool bar 2, are set with dish spring 6 on the broaching tool bar 2, and broaching tool bar 2 is not held and is fixed with dynamic balancing controller 1; Broaching tool bar 2 rear sleeve are equipped with knife striking cylinder 3, piston 27 and locating ring 4; Connecting pin 26 is connected as a single entity locating ring 4 and broaching tool bar 2, and broaching tool bar 2 front ends are equipped with balancing head 18 and balancing head fixed cover 19, and balancing head 18 is installed in balancing head fixed cover 19 inside; There are drive motors, disappear idle running and anticollision mechanism automatically in balancing head 18 inside; Can control the amount of unbalance of electric main axis rotation part in real time, and can prevent collision beyond the main shaft 25, reduce the time of emery wheel 16 near workpiece.The control cable of balancing head 18 is through broaching tool bar 2 inner main shaft 25 afterbodys that arrive, and dynamic balancing controller 1 is used to control the action and the receiving front-end signal of balancing head 18, and dynamic balancing controller 1 adopts the noncontact mode to receive signal, makes things convenient for the action of broaching tool bar 2 front and back.Main shaft 25 front ends are processed with two circular cones that do not wait tapering; The conical surface diameter of front cone is less than the conical surface diameter of back circular cone, and the conical surface of back circular cone contacts with grinding wheel chuck 14, and clamping has binding ring 20 on the conical surface of front cone; Binding ring 20 is the circular cone ring of three-clove style; Binding ring 20 is positioned at balancing head fixed cover 19 tops, is set with spring 21 on the binding ring 20, and the front cone face of main shaft 25 front ends is provided with guide finger 22; The lobe seam that guide finger 22 is positioned at binding ring 20 plays guide effect, and the front end of grinding wheel chuck 14 is fixed with baffle ring 17.
Main shaft oil of the present invention gets into rear bearing 5, fore bearing 12 and thrust bearing 13 respectively through sleeve 11, and they and main shaft 25 are formed the dynamic and static pressure main shafts jointly.Main shaft oil flows back to fueller through sleeve 11 after from rear bearing 5, fore bearing 12 and thrust bearing 13, flowing out, and seal cover 7 can prevent the leakage that main shaft is oily with protecgulum 23.
Motor water jacket 8 is installed in stator 9 outsides, and stator 9 can be cooled off when work fully, and rotor 10 is mainly processed with permanent magnet; Not only volume is little, and heating is few, and stator 9 had both been saved the space with the motor that rotor 10 is formed; Reduced power consumption, for main shaft 25 sufficient driving force is provided again.Its rotor 10 can adopt the interference assembling with main shaft 25, and is detachable behind the feeding pressure oil, and injuring part does not make things convenient for the later maintenance maintenance.
Hydraulic oil injects knife striking cylinder 3, and promote its internal piston 27 and travel forward, piston 27 extruding locating rings 4, because of connecting pin 26 is connected as a single entity locating ring 4 and broaching tool bar 2, so broaching tool bar 2 is followed and is travelled forward.Broaching tool bar 2 drives balancing head fixed cover 19 motion together; Binding ring 20 is three sections circular cone ring structures; When balancing head fixed cover 19 moves axially when dismantling grinding wheel chuck 14, binding ring 20 leans on spring 21 pulling force to move on main shaft 25 inner cone discs along guide finger 22, because main shaft 25 is conical surfaces; External diameter diminished when binding ring 20 moved, and guaranteed that grinding wheel chuck 14 is removed.The right half part of broaching tool bar 2 is grinding wheel chuck 14 state that is locked among Fig. 1, and left-half is that grinding wheel chuck 14 is about to released state.
