Abstract
The invention discloses a kind of swinging to protect saw bit mechanism, retaining sleeve including being located at saw blade both sides, described retaining sleeve is provided with cutting mouth, described retaining sleeve is driven by electric rotating machine, it can be rotated by the center of circle of saw blade main shaft, retaining sleeve is made up of fore-clamp gripping member, rear holder, and fore-clamp gripping member, rear holder are annular, saw blade fastens between, and fore-clamp gripping member, the outward flange diameter of rear holder are slightly smaller than saw blade diameter.The present invention is cutting workpiece for strengthening saw blade, when particularly just starting to cut workpiece, strengthens the rigidity of saw blade, reduces saw blade deflection, to improve cut quality and saw life.
Description
Technical field
It is specifically a kind of to be used for swinging shield veneer sawing machine the present invention relates to a kind of protection device of circular sawing machine saw blade
Structure.
Background technology
Circular sawing machine is that metal works are cut using saw blade, because circular saw blade diameter and thickness ratio are very big, and only
With center with two annulus clampings on main shaft, make its poor rigidity, job stability is not high, due to excircle of workpiece not only
It is whole, when starting a cut through, sawtooth both sides unbalance stress, easy inclined side, particularly after sawtooth blunt, resistance increase, it is more easy to make
Saw blade deforms, so as to influence Product Precision, or even saw blade rupture.Commonly increase at present in saw blade fringe region
Add it is several to fixed holder, when saw blade deforms more than it is a certain amount of when, there is holder to give spacing and strengthen rigidity, so as to carry
High saw life and cutting products quality.
But practical experience shows, when saw blade deflection maximum still when just starting a cut through that section of workpiece
Between.The position of its opening of traditional protection structure is fixed, and away from cut point.So traditional protection structure is to saw blade
Protecting effect can not have substantial raising all the time.
The content of the invention
To solve the problems, such as that background technology is mentioned, the present invention proposes following technical scheme：
A kind of swinging protects saw bit mechanism, including is located at the retaining sleeve of saw blade both sides, and described retaining sleeve is provided with cutting mouth,
Described retaining sleeve is driven by electric rotating machine, can be rotated by the center of circle of saw blade main shaft.
Further, retaining sleeve is made up of fore-clamp gripping member, rear holder, and fore-clamp gripping member, rear holder are annular, saw
Piece fastens between, and fore-clamp gripping member, the outward flange diameter of rear holder are slightly smaller than saw blade diameter.
Further, rear holder back is connected with disc connector, and described connector is arranged on saw by bearing
The output end of piece main shaft is covered, and described output end cap is bolted on main-gear box；Connector top edge be provided with
The non-fully gear member of the toothed disc occlusion of electric rotating machine roller end.
Further, described fore-clamp gripping member, rear holder are annular shape, and the two inside and outside edge cuts into inclined-plane.
Further, described fore-clamp gripping member, rear holder outward flange are equipped with two projections, as fore-clamp gripping member, after
The connecting portion of holder.
Further, described fore-clamp gripping member, rear holder are 0.02-0.04mm with the gap between saw blade.
When circular sawing machine is started working, retaining sleeve is rotated under the driving of electric rotating machine, and the top edge of cutting mouth is moved to
Close to the position of workpiece, retaining sleeve turns round under electric rotating machine driving after waiting saw blade incision workpiece, retracts initial position.
The present invention is cutting workpiece for strengthening saw blade, and when particularly just starting to cut workpiece, retaining sleeve is from cut point more
Closely, saw blade amplitude of deformation is reduced, greatly improves cut quality and saw life.

Embodiment
In order that those skilled in the art more fully understands technical scheme, the present invention is made below further
Explanation：
As Figure 1-3, a kind of swinging shield saw bit mechanism, including the retaining sleeve of saw blade both sides is located at, described clamping
It is arranged with cutting mouth 1；Retaining sleeve is made up of fore-clamp gripping member 2, rear holder 3, and fore-clamp gripping member 2, rear holder 3 are annular,
Saw blade 4 fastens between, and fore-clamp gripping member 2, the outward flange diameter of rear holder 3 are slightly smaller than the diameter of saw blade 4；Holder 3 afterwards
Back is connected with disc connector 5, and described connector 5 is arranged on by bearing 6 on the output end cap 8 of the main shaft 7 of saw blade 4,
Described output end cap 8 is bolted on main-gear box 9；The top edge of connector 5 is provided with the rotating shaft end of electric rotating machine 10
Non-fully gear member 12 that the toothed disc 11 in portion is engaged.
Further, described fore-clamp gripping member 2, rear holder 3 are annular shape, and the two inside and outside edge is cut into tiltedly
Face.
Further, described fore-clamp gripping member 2, the outward flange of rear holder 3 are equipped with two projections 13, as fore-clamp gripping member
2nd, the connecting portion of rear holder 3.
Further, described fore-clamp gripping member 2, rear holder 3 are 0.02-0.04mm with the gap between saw blade 4.
The initial position of mechanism is as shown in figure 4, when circular sawing machine is started working, driving of the retaining sleeve in electric rotating machine 10
Lower rotation, the top edge of cutting mouth 1 are moved close to the position of workpiece, as shown in Figure 5.Deng saw blade 4 cut workpiece after retaining sleeve
Turned round under the driving of electric rotating machine 10, retract the initial position shown in Fig. 4.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
