Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, further describe this utility model.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit protection domain of the present utility model.
nullRefer to Fig. 1、Fig. 4 ~ Fig. 7，A kind of grinding head motor，Including electric machine main shaft 3、Pull bar 2、Handle of a knife 1、Drawhead 5、Impact cylinder 6、Transmission oil cylinder 61、Locking nut 7、Thrust bearing 10、Stage clip 4、Motor upper cover 8 and motor bottom end cover 81，Electric machine main shaft 3 is provided with spindle hole 31，Pull bar 2 is located at spindle hole 31 center，In handle of a knife 1 is also provided in spindle hole 31 and can be connected with pull bar 2，Spindle hole 31 is provided with spindle hole shoulder 33，Being provided with cross section in the middle part of spindle hole 31 is polygonal gathering sill 34，Spindle hole 31 is installed handle of a knife 1 one end and is provided with male-tapered hole 36 and is provided with locating slot 35，Electric machine main shaft 3 outer surface is provided with the outer shoulder 32 of main shaft，The middle part of pull bar 2 is provided with the guide section 21 identical with gathering sill 34 shape of cross section on electric machine main shaft 3，Guide section 21 and gathering sill 34 are matched in clearance，Pull bar 2 coordinates one end to be provided with gap slot 23 and half slot 22 with handle of a knife 1，Handle of a knife 1 is provided with bearing pin 11、The conical surface 12 and hole 13, location，Handle of a knife 1 upper pin 11 and gap slot 23 on pull bar 2、Half slot 22 is matched in clearance；Drawhead 5 one end is fixed together with pull bar 2, and the other end has drawhead boss 52, and its outer surface is provided with spacing shoulder 53；Impact cylinder 6 is connected with transmission oil cylinder 61, impacts cylinder 6 and is provided with piston 62, and piston 62 is ined succession piston rod 63, and piston rod 63 is provided with the groove 631 coordinated with drawhead boss 52；Locking nut 7 inner surface tightens together with electric machine main shaft 3 one end, the hole of its upper surface coordinates with drawhead 5 crest clearance, spacing shoulder 53 external diameter of drawhead 5 is more than the internal diameter in the hole of locking nut 7 upper surface, locking nut lower surface 71 is pressed in one end of thrust bearing 10, thrust bearing 10 other end is pressed on motor upper cover 8, locking nut 7 is provided with a jackscrew 9, and locking nut 7 sidewall is provided with top wire hole, and jackscrew 9 holds out against locking nut 7 and electric machine main shaft 3 through top wire hole on locking nut 7；Stage clip 4 is enclosed within pull bar 2, is arranged between drawhead end face 51 and spindle hole shoulder 33, and stage clip 4 is pressured state when electric machine main shaft 3 works.
nullWhen handle of a knife 1 installed by needs，Transmission oil cylinder 61 drives impact cylinder 6，Thus drive piston rod 63 by piston rod groove 631、Pull bar is pressed for 2 times by drawhead boss 52，Stage clip 4 pressurized，Handle of a knife 1 is provided with in the male-tapered hole 36 of one end insertion electric machine main shaft 3 of bearing pin 11，Hole 13, location is allowed to be inserted by handle of a knife 1 time vertical with locating slot 34 on electric machine main shaft 3，At this moment in the bearing pin 11 on handle of a knife 1 enters the gap slot 23 of pull bar 2，When handle of a knife 1 can not continue into，Rotate handle of a knife 1，Make hole, location 13 and locating slot 35 centering on electric machine main shaft 3，So bearing pin 11 on handle of a knife 1 slips in half slot 22 smoothly，Complete upper slitter action，Due to hexagon gathering sill 34 and the cooperation of guide section 21，Pull bar 2 will not rotate during upper slitter，So upper slitter is accurate，Simple and convenient.
During grinding head motor work, transmission oil cylinder 61 pressure is recalled, piston 6 is up, depart from drawhead boss 52, the elastic force of stage clip 4 is pushed up drawhead end face shoulder 51, then move upward with pull bar 2, owing to spacing shoulder 53 external diameter is more than the aperture of locking nut 7, therefore when spacing shoulder 53 runs into locking nut 7, stage clip 4 stops moving upward, now stage clip 4 is still pressured state, the bearing pin 11 of handle of a knife 1 strained by so pull bar 2 by half slot 22, then tension handle of a knife 1, the conical surface 12 of handle of a knife 1 is fitted with the male-tapered hole 32 of electric machine main shaft 3 and is compressed, the stiction produced drives handle of a knife 1 to rotate with electric machine main shaft 3 together, thus the work of band rotary bistrique (not shown).
Refer to Fig. 2, Fig. 3, when needs unload handle of a knife 1, in two steps: the oil pressure that transmission oil cylinder 61 starts is less, the cylinder above transmission oil cylinder 61 passes to impact cylinder 6 by pipeline pressure, then piston 62 and piston rod 63 pressurized are descending, and piston rod groove 631 contacts with drawhead boss 52；Transmission oil cylinder 61 pressurizes afterwards, the pressure that generation moment is the biggest, by impact cylinder 6 and 62 piston rod 63 depressed fast of piston, overcome the elastic force that stage clip 4 is huge, depress pull bar 2, make the pivot pin 11 of handle of a knife 1 unclamp with the half slot 22 on pull bar 2, the conical surface 12 of handle of a knife 1 departs from the male-tapered hole 32 of electric machine main shaft 3, handle of a knife 1 rotates 90 degree, and bearing pin 11 is i.e. in gap slot 23 position, pulls out handle of a knife 1.
Being provided with limited block 64 below piston 63, descending spacing to piston rod 63, not so too big due to impulsive force, impact stroke becomes big, influences whether following device.Unloading cutter action is steady in order to unload cutter in two steps, reduces the impact of parts each to grinding head motor.
The impulsive force of transmission oil cylinder 61 is by pistion recess 61, drawhead boss 52, stage clip 4 is passed to again by 51 power of drawhead end face, 4 pressure of stage clip pass to electric machine main shaft 3 by spindle hole shoulder 33, electric machine main shaft 3 is to threaded with locking nut 7, adding the locking of jackscrew 9, surge has just passed to thrust bearing 10 by locking nut 7.
Bearing transmission oil cylinder 61 without thrust bearing 10 and unload cutter impulsive force, impulsive force will pass to motor bottom end cover 81 by the outer shoulder 33 of main shaft, and impulsive force is born by motor bottom end cover 81 completely, thus results in motor bottom end cover 81 jerk to such an extent as to damages.
The foregoing is only preferred embodiment of the present utility model, it is not to be regarded as limiting this utility model, all any amendment, equivalent and improvement etc. made in spirit of the present utility model and principle, within should be included in patent covering scope of the present utility model.
