Description
Technical field
The present invention relates to saw and cut technical field of tools, especially relate to a kind of pneumatic band sawing machine.
Background technology
For the object that prevents from occurring under coal mine gas explosion accident, under mine, stop to make with a chainsaw to wait electric tool and preferably use pneumatic tool.Such as, under mine, need to carry out gib, take grillage or with operations such as timber back of the body tops, therefore need to saw, cut a timber.Now, if adopt hand saws, when low the and utmost point of efficiency effort, especially timber is wet, basic saw is motionless; If employing electric saw, easily there is losing quick-fried generation spark and cause gas accident in this electric saw.And, when saw cuts timber under the high-risk environment such as chemical plant, also can face kindred circumstances.
For this reason, there is pneumatic band sawing machine.This pneumatic band sawing machine comprises saw body and handle, and this saw intracoelomic cavity is provided with air motor.Meanwhile, this saw body there is left part and right part, between this left part and right part, there is space, in the inner chamber of this left part and right part, be equipped with a rotating disk, in these 2 rotating disks, have a power to be connected to this air motor, and on these 2 rotating disks, cover is wound with saw blade, a part for this saw blade is positioned at this space.Certainly, this air motor is connected with high-pressure air source.That is, after this air motor work, drive turntable rotation, so saw blade rotation, timber is positioned in space, the saw that can accept saw blade cuts.Obviously, adopt after this pneumatic band sawing machine, improved to a certain extent production efficiency and avoided gas accident.
But the air motor of this pneumatic band sawing machine is realized power with rotating disk by worm-and-wheel gear and is connected, cause turntable rotation speed slower, reduced to a certain extent production efficiency.
Summary of the invention
The object of this invention is to provide a kind of pneumatic band sawing machine, it has feature simple in structure, efficiency is higher.
The technical solution adopted in the present invention is: pneumatic band sawing machine, comprise saw body and handle, wherein, this saw intracoelomic cavity is provided with air motor, this air motor has rotor, simultaneously, this saw body has left part and right part, between this left part and right part, there is space, in the inner chamber of this left part and right part, be equipped with a rotating disk, in these 2 rotating disks, there is a power to be connected to this rotor, and on these 2 rotating disks, cover is wound with saw blade, a part for this saw blade is positioned at this space, described rotor coaxial is fixed with rotor gear, described rotating disk is coaxially fixed with connection gear, and this rotor gear and the engagement of this connection gear.
The described rotating disk that is positioned at left side is furnished with tensioning holding device.
Described tensioning holding device is: in this left part inner chamber, be fixed with guide rail, on this guide rail, slide and be provided with slide plate, between this slide plate and the left end of this guide rail, be connected with extension spring, and the rotating disk on the left of being positioned at is fixed on this slide plate.
The advantage that the present invention has is: simple in structure, efficiency is higher.Pneumatic band sawing machine of the present invention improves for the power connected mode of air motor and rotating disk.That is, adopt gear-driven mode to make the rotor of this air motor and this sprocket wheel realize power connection.Like this, for the worm and gear of original technology, that gear drive has is easy to adjust, simple in structure, the feature of speed, thereby has effectively improved the production efficiency of this pneumatic band sawing machine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
The specific embodiment
Embodiment, as shown in Figure 1: pneumatic band sawing machine, comprises saw body 10 and handle 20.Wherein, these saw body 10 inner chambers are provided with air motor 30, and this air motor 30 has rotor 31.Meanwhile, this saw body 10 has left part 11 and right part 12, between this left part 11 and right part 12, has space 13.In the inner chamber of this left part 11 and right part 12, be all pivoted with a rotating disk 40, in these 2 rotating disks 40, have a power to be connected to this rotor 31, and on these 2 rotating disks 40, cover is wound with saw blade 50, a part for this saw blade 50 is positioned at this space 13.That is, after this saw blade 50 rotates, the timber that needs saw is cut is positioned in this space 13, can implement saw to this timber and cut.Further say, this rotor 31 is coaxially fixed with rotor gear 60, and this rotating disk 40 is coaxially fixed with and connects gear 70, and this rotor gear 60 engages with this connection gear 70.Obviously, be the rotating disk that power connects this rotor 31 with being connected the rotating disk that gear 70 is fixed on same axle.Like this, after these air motor 30 work, this rotor 31 drives this rotor gear 60 to rotate, this rotor gear 60 drives this connection gear 70 to rotate, this connection gear 70 drives one of them rotating disk 40 to rotate, and this rotating disk 40 drives this saw blade 50 to rotate, and then these saw blade 50 saws cut timber.Because this rotor 31 carries out power transmission with this rotating disk 40 by gear, thereby speed has higher production efficiency.
Optimize, the rotating disk 40 that is positioned at left side is furnished with tensioning holding device 80.Like this, can make this saw blade 50 there is all the time suitable tension force.Preferably, this tensioning holding device 80 is: in these left part 11 inner chambers, be fixed with guide rail 81, on this guide rail 81, slide and be provided with slide plate 82, between this slide plate 82 and the left end of this guide rail 81, be connected with extension spring 83, and the rotating disk 40 on the left of being positioned at is fixed on this slide plate 82.Like this, under the effect of this extension spring 83, the rotating disk 40 that is positioned at left side has the trend to left dislocation, that is to say, these 2 rotating disks 40 have mutually away from trend, thereby make this saw blade 50 all the time in tensioning state.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
