Utility model content
The purpose of this utility model is to provide for a kind of saw blade locking device, avoids saw blade from loosening, and ensure that saw blade to knife
Accuracy.
According to one side of the present utility model, there is provided saw blade locking device, including saw blade fixing axle and housing screw,
Saw blade lower platen, saw blade and saw blade top board is nested and fixed in saw blade fixing axle successively, and saw blade fixing axle is also socketed with lock successively
Press plate and locking nut, locking pressure plate is built in locking nut, and housing screw is threadedly connected to locking nut, and is pressed in lock
Press plate, locking nut, locking pressure plate axial compression are in saw blade top board.
Turn housing screw is tightened against locking nut so that locking nut once locks saw blade top board, while compresses spiral shell
Nail is resisted against locking pressure plate so that locking pressure plate secondary locking saw blade top board, passes through two layers of locking pressure plate and locking nut
After locking, locking nut will not be loosened, and the displacement of saw blade circumferencial direction will not be produced during locking, ensure that saw blade pair
The accuracy of knife.
In some embodiments, saw blade locking device also includes attachment screw, and attachment screw is threadedly connected to locking pressure
Plate and locking nut.Thus, locking pressure plate and locking nut are connected by attachment screw, can be once taken when saw blade unlocks
Go out, it is easy to operate.
In some embodiments, saw blade centralized positioning set, saw blade centralized positioning set is also nested and fixed in saw blade fixing axle
Located at the center of saw blade, and axial compression is in saw blade lower platen, saw blade top board.Thus, saw blade centralized positioning set ensure that saw
Piece fixing axle is located at the center of saw blade so that saw blade is reliable and stable when rotating at a high speed.
In some embodiments, saw blade fixes the tip of the axis and is nested and fixed ring flange, and ring flange is close under saw blade
Pressing plate.Thus, by ring flange power connector in reductor and servomotor, so as to drive saw blade to rotate at a high speed.
In some embodiments, housing screw, attachment screw are soket head cap screw.Thus, using soket head cap screw
It is easy to fasten and dismantles.
In some embodiments, saw blade top board is provided with handle.Thus, during dismounting, handle is set to be easy to from saw blade
Top take out saw blade top board.
The utility model is simple in construction, convenient disassembly, locking are firm, is effectively improved saw blade to knife precision.
Brief description of the drawings
Fig. 1 is the schematic top plan view of the saw blade locking device of the embodiment of the utility model one；
Fig. 2 is the A-A sectional views of saw blade locking device shown in Fig. 1；
Fig. 3 is the B-B sectional views of saw blade locking device shown in Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, the saw blade locking device includes saw blade fixing axle 1, housing screw 2 and attachment screw 3, saw blade
Fixing axle 1 is socketed saw blade lower platen 4, saw blade 5, saw blade top board 6, locking pressure plate 7 and locking nut 8 successively, and saw blade 5 is annular saw
Piece, saw blade lower platen 4, saw blade 5, saw blade top board 6 are interference fitted with saw blade fixing axle 1 fix respectively, and locking pressure plate 7 is built in
Locking nut 8, housing screw 2 is threadedly connected to locking nut 8, and is compressed against locking pressure plate 7.Housing screw 2 has two,
It is soket head cap screw, when tightening housing screw 2, locking nut 8, the axial compression of locking pressure plate 7 are in saw blade top board 6.
Attachment screw 3 is threadedly connected to locking pressure plate 7 and locking nut 8, and attachment screw 3 has two, is interior hexagonal spiral shell
Nail, the center of the insertion saw blade 5 of saw blade centralized positioning set 9, saw blade centralized positioning set 9 are socketed on saw blade fixing axle 1 and are interference fitted
Fixed, saw blade centralized positioning covers 9 axial compressions in saw blade lower platen 4, saw blade top board 6, so as to ensure that saw blade fixing axle 1
In the center of saw blade 5 so that saw blade 5 is reliable and stable when rotating at a high speed, and ring flange is nested and fixed in the end of saw blade fixing axle 1
10, ring flange 10 is close to saw blade lower platen 4, by the power connector of ring flange 10 in reductor and servomotor, so as to drive
Saw blade 5 rotates at a high speed.The riveting of saw blade top board 6 has two handles 11, during dismounting, holds handle 11 and is easy to from the top of saw blade 5
Saw blade top board 6 is taken out, and then takes out saw blade 5.
Turn housing screw 2 and be tightened against locking nut 8 so that locking nut 8 once locks saw blade top board 6, simultaneously
Housing screw 2 is resisted against locking pressure plate 7 so that the secondary locking saw blade top board 6 of locking pressure plate 7, passes through locking pressure plate 7 and locking
After two layers of locking of nut 8, locking nut 8 will not be loosened, and the position of the circumferencial direction of saw blade 5 will not be produced during locking
Move, ensure that accuracy of the saw blade 5 to knife.Locking pressure plate 7 and locking nut 8 are connected by attachment screw 3, unlocked in saw blade 5
When locking pressure plate 7 and locking nut 8 can once be taken out, it is easy to operate.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
