Description
Technical field
The utility model relates to field of power tools, especially a kind of hand-held sander that the woodworks such as floor, metope is carried out to polishing operation.
Background technology
Hand-held sander has been widely used in all trades and professions as a kind of conventional milling tools.When most hand-held sanders are polished on to be processed on the market, mostly all there is spin moment and load oscillation phenomenon, especially 1/2nd dull and stereotyped sand.This phenomenon causes the handling variation of hand-held sander, easily to a LRO Lateral Runout, and uses for a long time operator's wrist of hand-held sander easily tired.
The counterweight that existing hand-held sander has an overcome friction drift angle by use can be improved load and vibrates, but has tended to increase the moment of spinning of hand-held sander.If used, do not have the counterweight of overcome friction drift angle can improve the hand-held sander phenomenon of spinning, but load vibration characteristics is bad.
Summary of the invention
For the defect of above-mentioned prior art existence, the utility model provides a kind of simultaneously taking into account to alleviate the hand-held sander that spins and reduce load vibration.
A hand-held sander, comprises body, motor, driving shaft, eccentric shaft, securing member, fan and base plate; Motor is contained in casing, and connected by the first end of driving shaft, driving shaft can rotate around first axle; On the body of fan, be provided with first surface and the second surface relative with first surface, driving shaft the second end combines with the installing hole on fan first surface, and eccentric shaft can be around the second axis rotation, and described first axle is parallel with the second axis; The first surface of described fan is provided with the first fan blade district of common fan blade part, and wherein said eccentric shaft is arranged on the second surface of fan, and on the first and second surfaces of described fan, at least one of them is provided with weighted areas.
Nearly step ground, described weighted areas comprises the first weighted areas on the first surface that is arranged on fan and is arranged on the second weighted areas of the second surface of fan.
Nearly step ground, the counterweight of described the first and second weighted areas is all the fan blade part of fan.
Nearly step ground, the thickness of the fan blade part of described the first and second weighted areas is greater than the common fan blade part in the first and second fan blade districts.
Nearly step ground, described fan blade part is not all that the plane that first axle and the second axis form is divided equally.
Nearly step ground, the excessively face of being combined with the second surface of fan of the fan blade part on described fan second surface is smooth excessiveness face.
The moment of spinning when this balance weight structure can alleviate or eliminate hand-held sander and moves on working face, significantly improves the navigability of dull and stereotyped sand.Meanwhile, this balance weight structure can alleviate hand-held sander load vibration, and the comfort level when increasing operator and using dull and stereotyped sand has also increased the sanding efficiency of dull and stereotyped sand.

The specific embodiment
Below in conjunction with accompanying drawing, the hand-held sander of the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, take flat sanding machine as example, this hand-held sander comprises body 1, motor 2, driving shaft 4, eccentric shaft 5, securing member 6, fan 7 and base plate 3.Motor 2 is contained in casing 1, is connected with the first end 41 of driving shaft 4, and driving shaft 4 can be around first axle 10 rotations.On the body of fan 7, be provided with first surface 71 and the second surface 72 relative with first surface 71, driving shaft the second end 42 combines with the installing hole 70 on fan 7 first surfaces, the second surface 72 of fan 7 is provided with eccentric shaft 5, eccentric shaft 5 is around the second axis 20 rotations, and wherein first axle 10 is parallel with the second axis 20.The utility model provide three kinds of fans design, can both alleviate hand-held sander load vibration.
As shown in Figures 2 and 3, in present embodiment one, the first surface 71a of fan 7a is provided with the first fan blade district 73a， fan blade district 73a and is provided with a plurality of common fan blade part 77a distributing radially, is provided with the second weighted areas 76a with balancing weight 79a on second surface 72a.
As shown in Figures 4 and 5, in present embodiment two, the first surface 71b of fan 7b is provided with on the first fan blade district 73b， fan blade district 73b has a plurality of common fan blade part 77b distributing radially, is provided with in addition the first weighted areas 74b with balancing weight 79b on the first surface of fan blade.On the second surface 72b of fan 7b, be provided with the second weighted areas 76b with balancing weight 79b, on second surface 72b, be also provided with the second fan blade district 75b， fan blade district 75b and be provided with a plurality of common fan blade part 77b distributing radially.
Between the excessive face 79b of common fan blade part 77b on second 72b of fan 7b and counterweight fan blade part 78b and combination, for seamlessly transitting, this excessive face is not right angle, is not easy like this to pile laying dust bits.
As shown in Fig. 6 to 9, in present embodiment three, the first surface 71c of fan 7c is provided with on the first fan blade district 73c， fan blade district 73c has a plurality of common fan blade part 77c distributing radially, is provided with in addition the first weighted areas 74c on the first surface of fan blade.A plurality of counterweight fan blade part 78c of the upper employing of the first weighted areas 74c.The second surface 72c of fan 7c is provided with the second fan blade district 75c， fan blade district 75c and is provided with a plurality of common fan blade part 77c distributing radially.The second surface 72c of fan 7c is also provided with the second weighted areas 76c, and the second weighted areas 76c adopts a plurality of counterweight fan blade part 78c.
In the present embodiment, wherein the thickness of counterweight fan blade part 78c is greater than common fan blade part 77c, and the thickness of a plurality of common fan blade parts 77 is equal fan blade parts, the thickness of a plurality of counterweight fan blade part 78c can be designed to that thickness equates or fan blade part not etc. according to actual needs.
A plurality of common fan blade part 77c distribute and form respectively the first fan blade district 73c and the second fan blade district 75c according to some, a plurality of counterweight fan blade part 78c distribute and to have formed the first weighted areas 74c and the second weighted areas 76c according to some, and the plane that the counterweight fan blade part 78c that wherein forms first, second weighted areas 76c formation is not all formed by first axle 10 and the second axis 20 is divided equally.
Identical with embodiment two, between the excessive face 79c of the common fan blade part 77c on second 72c of fan 7c and counterweight fan blade part 78c and combination, for seamlessly transitting, this excessive face is not right angle, is not easy like this to pile laying dust bits.
The utility model is transformed by the fan to hand-held sander, be fan integrated eccentric shaft, utilize fan blade part and independent balancing weight combination, or counterweight be distributed in counterweight fan blade part, form the first weighted areas and the second weighted areas, thereby realized the function of counterweight.
Thereby in the hand-held sander in the utility model, do not need additionally to increase major-minor counterweight part, this form structure is simple, easy to assembly, with low cost, and can go to set according to working condition or machine performance distribution or the shape of fan blade part, thereby obtain best balance numerical value, and then can make spin moment and the vibration of flat sanding machine all obtain largely to improve.
Above-described embodiment be take flat sanding machine as example, but the utility model is not limited on this product, and the utility model also can be applicable on other sanders that need balance, for example triangle sand.
