Description

There is movable protective, the clamping of saw blade location and the beveler of dust-absorbing function
Technical field
The present invention relates to a kind of beveler, particularly relate to that there is movable protective, the clamping of saw blade location and dust suction merit The beveler of energy.
Background technology
At present, cutting machine is widely used in the cutting processing of various different workpieces, and beveler is as cutting machine One therein, also achieves large development.Existing beveler generally comprises base, the work being located on base Station and rotating mechanism, the saw blade for cutting workpiece being connected on rotating mechanism by support, in certain journey The cutting task of some section bar or workpiece can be completed on degree, but generally there are the following problems: one is the absence of dust suction Device and lack dust-absorbing function, or be provided with dust exhaust apparatus, can meet the dust-absorbing function under certain condition, but this Class dust exhaust apparatus is cutting machine dust exhaust apparatus (such as vacuum cleaner) in addition greatly, and this mode takies in a large number Space and pick-up performance are the best;Also there are cutting machine and dust exhaust apparatus integrated setting, suction can be played to a certain extent Dirt function, but mostly cannot play dynamic dust-absorbing function and structure is more complicated;Two is saw blade positioning clamping device Including clip plate and outer plate, saw blade is located between clip plate and outer plate and is clamped, but clip plate is with outer The surface of pressing plate is burnishing surface, and saw blade is only merely in the platen surface being clamped at clip plate and outer plate, Make to position clamping effect poor, and clip plate is bigger with outer plate occupied area so that be located in intrinsic pressure The output shaft of plate and outer plate is the longest, so that the protective cover width being located at outside saw blade is the biggest, thus causes Consumptive material is bigger and relatively costly;Three is the commonly used fixed blade guard of preventer or fixed protection plate, also has Fixed blade guard or fixed protection plate install additional flexible blade guard or mobile protective panel, but above-mentioned preventer It is primarily present and has a problem in that: the protective range being on the one hand fixed blade guard or fixed protection plate is limited, cuts The activity of cutter sweep can not be followed and movable protective when cutting device cutting;On the other hand it is existing fixing anti- On guard shield there is flexible blade guard or mobile protective panel and fixed blade guard in band flexible blade guard or mobile protective panel Or fixed protection plate is not that concentric is arranged so that flexible blade guard or mobile protective panel consumptive material is more and weight Heavier and relatively costly.
Summary of the invention
The present invention is directed to beveler in prior art and there is three below shortcoming: one is the absence of dust exhaust apparatus and lacks Weary dust-absorbing function, or it is provided with dust exhaust apparatus, the dust-absorbing function under certain condition can be met, but this type of dust suction fills Putting is cutting machine dust exhaust apparatus (such as vacuum cleaner) in addition greatly, and this mode takies big quantity space and suction Dirt poor effect;Also there are cutting machine and dust exhaust apparatus integrated setting, dust-absorbing function can be played to a certain extent, But mostly cannot play dynamic dust-absorbing function and structure is more complicated;Two to be that saw blade positioning clamping device includes intrinsic pressure Plate and outer plate, saw blade is located between clip plate and outer plate and is clamped, but clip plate and the table of outer plate Face is burnishing surface, and saw blade is only merely in the platen surface being clamped at clip plate and outer plate so that location Clamping effect is poor, and clip plate is bigger with outer plate occupied area so that be located in clip plate and external pressure The output shaft of plate is the longest, so that the protective cover width being located at outside saw blade is the biggest, thus causes consumptive material bigger And it is relatively costly;Three is the commonly used fixed blade guard of preventer or fixed protection plate, also has fixing anti- Install flexible blade guard or mobile protective panel on guard shield or fixed protection plate additional, but above-mentioned preventer is primarily present It has a problem in that: the protective range being on the one hand fixed blade guard or fixed protection plate is limited, and cutter sweep is cut The activity of cutter sweep can not be followed and movable protective when cutting;On the other hand it is to carry on existing fixed blade guard There is flexible blade guard or mobile protective panel and fixed blade guard or fixing anti-in flexible blade guard or mobile protective panel Backplate is not that concentric is arranged so that flexible blade guard or mobile protective panel consumptive material is more and heavier-weight forms This is higher, the shortcoming that the present invention exists according to above-mentioned existing beveler, it is provided that one has movable anti-simultaneously Protect, saw blade location clamps and dust-absorbing function and lower-cost beveler.
