Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figures 1 to 4, reliability service saw blade mounting structure is quickly changed, including changes saw blades groups 1, rotating shaft body 2
With saw blade locking device 3, the rotating shaft body 2 includes rotating spindle 21, chuck 22, screw rod 23, covers 24 surely, the saw blade locking
Device 3 includes locking cylinder 31, double nut 32, flower-shape platen 33, and the locking cylinder 31 includes locking cylinder body 311, locking cylinder plug
312, described change offers flower pattern hole among saw blades groups 1, and installed in the left side of chuck 22, the chuck 22, which is arranged on, rotates master
In the circumferential exterior surface of axle 21, the screw rod 23 and set 24 is installed in inside rotating spindle 21 surely, the right-hand member set of screw rod 23
It is connected in fixed set 24,24 bottoms that cover surely are contacted with the nut of screw rod 23, and the locking cylinder body 311, which is connected through a screw thread, to be exposed
Surely the left end of screw rod 23 of set 24, and be connected by external screw thread with double nut 32, the locking cylinder plug 312 is located at locking cylinder body
At 311 right output port, and the top end face of fixed set 24 is pressed against, peripheral shape and the size and replacing saw blade of the flower-shape platen 33
Flower pattern hole shape in group 1 is caused with size uniformity, and the flower-shape platen 33 is set in outside the locking cylinder body 311 on the right side of double nut 32
Surface, and the left surface with changing saw blades groups 1 contacts.
The replacing saw blades groups 1 include saw blade 11, saw disc 12, and the saw blade 11 is fixed on the right side of saw disc 12.
Multiple corresponding positioning bolt holes, the saw disc 12 and saw are provided with the edge of saw disc 12 and saw blade 11
Piece 11 is attached by multiple bolts 13 in positioning bolt hole, and the chuck 22 is provided with multiple with positioning
The corresponding positioning hole of bolt hole, size and the bolt head of the positioning hole match.
Surely the top end face of the set 24 is bolted to connection in one end of rotating spindle 21.
In the circumferential exterior surface of the rotating spindle 21 stopper slot is arranged on circumferentially arranged with stopper slot, the chuck 22
It is interior.
The locking cylinder body 311 is provided with oil guide pipe.
Installation and the unloading process that saw blades groups 1 are changed in the present embodiment are as follows：
Saw blades groups 1 will be changed to move to the right from the left side of saw blade locking device 3, by flower pattern hole to good flower-shape platen 33
Pass and be adjacent on chuck 22, by changing the positioning hole on the bolt installed in saw blades groups 1 and chuck 22
Cooperation is positioned, and without twisting bolt again, while is also saved and will be changed saw blades groups 1 when bundle of lines is closed to rotating spindle 21
Between；
It is in 45 degree of positions to rotate flower-shape platen 33 with changing saw blades groups 1, compression position as shown in Figure 3, is then tightened
Double nut 32 makes the pre-pressing of flower-shape platen 33 change saw blades groups 1；
The body of locking cylinder 311 is connected by inner trapezoidal thread with screw rod 23, is connected by external screw thread with double nut 32, locking
Cylinder plug 312 presses against fixed set 24, covers 24 surely and then pushes down the nut of screw rod 23.Hydraulic oil now is squeezed into locking cylinder 31, makes lock
Tight cylinder body 311 and locking cylinder plug 312 produce relative motion, locking cylinder plug 312 is pressed against screw rod 23, it is led relative to rotation
Axle 21 does not produce relative motion；And locking cylinder body 311 makes screw rod 23 produce tensile elasticity deformation, now double spiral shells the stretching of screw rod 23
Gap is produced between mother 32 and flower-shape platen 33, then tightening double nut 32 again makes flower-shape platen 33 finally compress replacing saw blades groups 1；
Then oil pressure is cancelled, now the powerful elastic deformation force of screw rod 23 will tightly change saw blades groups 1 and compress, and pass through
Frictional force, the operation of the safety and steady of saw blades groups 1 is changed, and be not in because long-term use of damage changes the huge of rotating spindle 21
Loss, only it need to change small parts screw rod 23.
Unloading process is：Hydraulic oil is squeezed into locking cylinder 31, screw rod 23 produces tensile elasticity deformation again, now double nut
Gap is produced between 32 and flower-shape platen 33, then unscrewing double nut 32 again makes flower-shape platen 33 depart from replacing saw blades groups 1, rotation
Flower-shape platen 33 will be changed saw blades groups 1 and hung out from side to the flower hole of good replacing saw blades groups 1.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
