Description
Technical field
This utility model relates to band sawing machine technology, is specifically related to the fast replacing device of a kind of band saw.
Background technology
During existing band sawing machine uses, its saw blade is to rotate by rotary knob, increases tensioning spring compression stress and comes
The distance between two belt wheels of saw blade is fixed in tensioning, makes saw blade tensioning.
When saw blade changed by needs, need opposite direction rotary knob again, reduce spring compression force unclamp two belt wheels it
Between distance, loosen saw blade, after more finishing changing saw blade, also need to repeat above-mentioned tensioning program, tensioning saw blade, not only need again
Operation, in-convenience in use, and the tensioned degree before and after changing has error, the cutting accuracy of twice saw blade before and after causing changing
Change.
Utility model content
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of band sawing machine
The fast replacing device of saw blade.
Technical scheme: the fast replacing device of a kind of band saw described in the utility model, including frame, is installed on frame
The workbench in centre position, is installed on top panel and the upper belt-wheel of frame upper end, and is installed on the lower belt wheel of frame lower end, institute
The top stating top panel is provided with knob, and knob extends downwardly in lower panel and is cased with tensioning spring；The side of upper top panel is installed
Having fixed plate, upper belt-wheel to be fixed by fixed plate, be cased with saw blade between upper belt-wheel and lower belt wheel, the opposite side of top panel is provided with
Pressing handle soon, after fast pressure handle sequentially passes through top panel and fixed plate, connection has fast briquetting, fast briquetting to be that eccentric state is arranged, Gu
Determining active card on plate and be buckled with bearing pin, bearing pin is positioned at immediately below fast briquetting.
In order to prevent operator from operationally being accidentally injured, described top panel is provided with near workbench one end the anti-of saw blade
Guard shield.
Further, described bearing pin is movably connected on fixed plate by lifter plate, is provided with steel between fixed plate and lifter plate
Plate, upper belt-wheel is equipped with mounting hole, bearing pin by Interal fixation in fixed plate, the side, two ends of fixed plate, steel plate and lifter plate
It is stuck in successively in the mounting hole of fixed plate, steel plate and lifter plate, is so easy to bearing pin and moves up and down under the effect of fast briquetting.
Beneficial effect: this utility model can quick saw blade replacement, improve work efficiency, and can accurately change, have
Effect ground improves the service life of saw blade.

Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to
Described embodiment.
As shown in Figures 1 to 5, the fast replacing device of a kind of band saw 8 described in the utility model, including frame 1, peace
It is loaded on the workbench in frame 1 centre position, is installed on top panel 2 and the upper belt-wheel 3 of frame 1 upper end, and is installed on frame 1 time
The lower belt wheel 4 of end, the top of described top panel 2 is provided with knob 5, and knob 5 extends downwardly in lower panel and is cased with tensioning spring 6；
The side of upper top panel 2 is provided with fixed plate 7, and upper belt-wheel 3 is fixed by fixed plate 7, is cased with between upper belt-wheel 3 and lower belt wheel 4
Saw blade 8, the opposite side of top panel 2 is provided with fast pressure handle 9, and fast pressure handle 9 connects after sequentially passing through top panel 2 and fixed plate 7
Having fast briquetting 10, fast briquetting 10 to arrange in eccentric state, in fixed plate 7, also active card is buckled with bearing pin 11, and bearing pin 11 is positioned at fast pressure
Immediately below block 10.
In order to prevent operator from operationally being accidentally injured, top panel 2 is provided with saw blade protective cover near workbench one end
12。
Specific works principle of the present utility model is: under driven by motor, belt wheel 4 and upper belt-wheel 3 rotate, and then make saw blade 8
Running is cut.
When saw blade 8 changed by needs, rotate fast pressure handle 9, drive fast briquetting 10 to depress bearing pin 11, owing to bearing pin 11 is with solid
Determine plate 7 and upper belt-wheel 3 is assembled together, so make whole upper belt-wheel 3 assembly will move down rapidly certain distance, i.e. upper belt-wheel 3
And the Distance Shortened between lower belt wheel 4, saw blade 8 can unclamp, and then operator are replaced.Wherein, when fast briquetting 10 to
Under when pressing bearing pin 11, bearing pin 11 declines along lifter plate 14, drives steel plate 15 (i.e. upper belt-wheel 3) also to move down.
After replacing completes, reversely rotating fast pressure handle 9, fast briquetting 10 return, upper belt-wheel assembly acts at tensioning spring 6
Under (tensioning spring 6 resilience, drive lifting 14 plates move up, thus upper belt-wheel 3 gos up), be in the most again tensioning state.
In whole Renewal process, the rate of tension of tensioning spring 6 does not changes, with without again regulating tensioning spring 6
Compression stress and upper belt-wheel 3 before and after beat, even if being in the same tensioning, front and back beat degree before and after saw blade 8.
