Abstract
A saw blade, which can be mounted on the output shaft of an oscillating machine, comprises a mounting part adapting to the output shaft and a working part fixedly connected with the mounting part, wherein the working part comprises two back-to-back surfaces which are perpendicular to the output shaft; sawteeth are formed in at least part of the outer edge of the working part; a polishing layer is arranged on at least one of the back-to-back surfaces. The saw blade is characterized in that an interval is reserved between the polishing layer and the sawteeth in a direction perpendicular to the output shaft. Therefore, the wear of the polishing layer, which is caused when abrasive grains rub the surface of a workpiece during saw-cutting, can be avoided to prolong the service life of the saw blade; moreover, the increase of power consumption of the oscillating machine, which is caused when the abrasive grains rub the surface of a workpiece during saw-cutting, can be avoided.
Description
Technical field
The utility model relates to a kind of saw blade, especially a kind of saw blade of applying on the swing-type power tool of hand-held.
Background technology
Oscillating machine is the swing-type power tool of the common hand-held of industry, and its operation principle is that output shaft is done oscillating motion around axial line.Therefore,, when user installs after different working heads on output shaft, can realize multiple different operating function.Common working head comprises saw blade, frosted dish, scraper etc., can realize as work requirements such as sawing, cut, grind, scrape.
Be furnished with the saw blade of abrasive particle as the working head of oscillating machine, both can carry out sawing to workpiece, can polish to workpiece again, in the time of in working order, vibrate at a high speed, thereby very easy loss, as easily-consumed products, how reducing loss, increasing the life-span is industry urgent problem.
Utility model content
Technical problem to be solved in the utility model is: the oscillating machine saw blade that a kind of loss is low, the life-span is long is provided.
The technical solution of the utility model is: a kind of saw blade, can be arranged on oscillating machine output shaft, described saw blade has the installation portion connecting with described output shaft and the operate portions being fixedly connected with described installation portion, described operate portions has two faces that deviate from mutually, described two faces that deviate from are mutually vertical with described output shaft, the outer rim of described operate portions is provided with sawtooth at least partly, two faces that deviate from mutually of described operate portions are at least furnished with polishing layer on one of them, it is characterized in that: on the bearing of trend along vertical described output shaft, between described polishing layer and described sawtooth, there is interval.
The beneficial effects of the utility model are: between polishing layer and sawtooth, keep interval, in the time of just can avoiding sawing, abrasive particle friction surface of the work increases the loss of polishing layer, thereby also avoid abrasive particle friction surface of the work to increase oscillating machine power consumption the service life of improving saw blade.
Preferably, described saw blade is straight blade.Preferably, to the distance of described sawtooth, to be described operate portions arrive half away from the distance of one end of described installation portion near one end of described installation portion to described polishing layer.The width of described polishing layer is identical with the width of described saw blade.
Certainly, described saw blade can be also saw blade, and described polishing layer is arranged at described operate portions surface around described installation portion circlewise.Certainly, described saw blade can be also semicircle saw blade, and described polishing layer " U " font ground is arranged at described operate portions surface around described installation portion.
Preferably, described polishing layer consists of the abrasive particle being fixed on saw blade.
Preferably, described abrasive particle is diamond abrasive grain.The abrasive particle that adopts diamond material, is covered with saw blade by abrasive particle broad ways and can improves grinding efficiency.
Preferably, described abrasive particle average-size is 60 orders.
Certainly, described polishing layer also can consist of the sand paper being fixed on saw blade.
Accompanying drawing explanation
Identical label in accompanying drawing and description and symbol are for representing element identical or that be equal to.
Fig. 1 is that the utility model saw blade is installed on the schematic diagram on oscillating machine.
Fig. 2 is the utility model straight blade upward view.

Fig. 4 is the utility model saw blade upward view.
Wherein,
1. oscillating machine 3. saw blade 5. installation portion 7. operate portions
9. sawtooth 11. polishings layer
The specific embodiment
The specific embodiment of the present utility model is as follows:
Shown in figure 1, the utility model is the saw blade 3 that is applicable to oscillating machine 1, and saw blade 3 can be installed on oscillating machine 1 output shaft.Saw blade 3 comprises installation portion 5 and operate portions 7.Saw blade 3 is coupled on output shaft by its installation portion 5, as the working head of oscillating machine 1, workpiece is processed.Installation portion 5 is fixedly connected with operate portions 7.
Shown in figure 2, operate portions 7 has two faces that deviate from mutually.Described two faces that deviate from are mutually vertical with output shaft.The outer rim of operate portions 7 is provided with sawtooth 9 at least partly.In one of them of two faces that deviate from mutually of operate portions 7, be provided with polishing layer 11.Certainly, on two faces, being provided with polishing layer 11 is also fine.On the bearing of trend along vertical described output shaft, between polishing layer 11 and described sawtooth 9, there is interval.
Polishing layer 11 border nearest apart from sawtooth 9 are positioned at the centre of operate portions 7, that is to say that sawtooth 9 is when carrying out sawing, and polishing layer 11 can't touch workpiece.So, in the time of can avoiding sawing, abrasive particle friction surface of the work increases the loss of polishing layer, thus the service life of improving saw blade, and when also avoiding sawing, abrasive particle friction surface of the work causes oscillating machine power consumption to increase.
In the present embodiment, saw blade 3 is straight blade.Preferably, to be described operate portions 7 arrive half away from the distance of one end of described installation portion 5 near one end of described installation portion 5 to polishing layer 11 minimum distance to described sawtooth 9.Preferably, the width of polishing layer 11 is identical with the width of saw blade 3, that is to say that the polishing layer 11 adding on saw blade 3 is along not leaving space on saw blade 3 widths.
Polishing layer 11 consists of the abrasive particle being fixed on saw blade in the present embodiment.Preferably, abrasive particle is diamond abrasive grain.The average-size of abrasive particle is 60 orders.So can improve the efficiency of polishing.Certainly, polishing layer 11 also can consist of the sand paper being fixed on saw blade.
Shown in figure 3, saw blade 3 can be also saw blade, and polishing layer 11 is arranged at operate portions 7 surfaces around installation portion 5 circlewise.Polishing layer 11 distance to sawtooth 9 are half of operate portions 7 radiuses.
Shown in figure 4, saw blade 3 can be also semicircle saw blade, and polishing layer 11 " U " shape ground is arranged at operate portions 7 surfaces around installation portion 5.Polishing layer 11 semi-circular segments are half of operate portions radius to the distance of sawtooth 9.
The utility model saw blade is not limited to above embodiment, and the structure based on the utility model design is all within protection domain of the present utility model.
