Description
Technical field
The present invention relates to the electronic grinding tool of a kind of multi-functional hand-held formula.
Background technology
Existing sander comprises round sand machine and dull and stereotyped sand etc., wherein the polishing base plate of round sand machine can freely be rotated with respect to driving shaft, be used for the relatively large material of grinding, the polishing base plate of dull and stereotyped sand is merely able to do the orbital motion of rule, is applicable to grinding material in a small amount.U.S. Pat 6,132,300 disclose a kind of two function sanders in October, 2000, by cooperating with a jockey that comprises a plurality of rigid members and a plurality of flexible cylinders, circle sand machine and two kinds of used polishing base plate of dull and stereotyped sand all can be arranged on the same sander, realize two kinds of functions.But the complex structure of jockey, and the moment that flexible cylinder is subjected to is big, loses efficacy easily, and the material requirements height to flexible cylinder during production causes cost to increase.
Summary of the invention
For addressing the above problem, the invention provides a kind of simple in structure, two function sanders cheaply.
The object of the present invention is achieved like this: a kind of hand held electric tool, comprise: around first driving shaft of first axle rotation, wind second driving shaft with respect to second axis rotation of first axle radial offset, and the housing that holds first driving shaft and second driving shaft, interchangeable first polishing base plate and second polishing base plate of being equipped with on described second driving shaft, it is characterized in that: described first polishing base plate can freely be rotated with respect to described second axis, and in described second polishing base plate and the described housing one is provided with respect to described second radial axis and is resisted against flexible member in described second polishing base plate and the described housing another; Extend internally out boss and described flexible member of the inwall of described housing matches; Described flexible member comprises the bearing that is connected on described second polishing base plate, be arranged on cutting ferrule on the described bearing, be contained in the spring in the cutting ferrule and be resisted against steel ball on the spring; Described flexible member comprises by folding horizontal folding limit that forms of flexible material and vertical folded edge; Also be provided with on described second polishing base plate and comprise support spring that is contained in the groove of offering on the polishing base plate upper surface and the supporting component that supports steel ball.
Compared with prior art, the invention has the beneficial effects as follows: sander adopts integrally-built stop device, radially limits freely rotating of polishing base plate, and is simple in structure, and stop device is subjected to moment little, be difficult for losing efficacy, and handling ease, cost is low.

The specific embodiment
Referring to attached Fig. 1 and 2, the first embodiment of the present invention has been installed second polishing base plate 22.Sander comprises upper shell 2, be contained in the motor (not shown) in the upper shell 2, by clutch shaft bearing 8 be supported in the lower house 20 link to each other with motor, around first driving shaft 6 of first axle 4 rotation, be supported on the fan 7 in the lower house 20, wind second driving shaft 12 that second axis 10 with respect to first axle 4 radial offset rotates by second bearing 14, and be installed in second polishing base plate 22 on second driving shaft 12 by pressing plate 16 and screw 18.Lower house 20 is provided with open-ended, first driving shaft 6 and second driving shaft 12 are arranged on wherein, the inwall of lower house 20 boss 30 that extends internally out matches with the flexible member 31 that is provided with on the upper surface of polishing base plate 22, thereby prevents that polishing base plate 22 from freely rotating with respect to second driving shaft 12.The number of boss 30 can be identical with the number of flexible member 31, and the shape of boss 30 can be any shape that matches with flexible member 31 that is beneficial to.It will be recognized by those skilled in the art that flexible member 31 can be arranged on in the housing 20 and second polishing base plate 22 one, for second driving shaft 12, radially be resisted against in the housing 20 and second polishing base plate 22 another.When driven by motor first driving shaft 6 rotates, because second polishing base plate 22 that second driving shaft 12 with respect to the 6 radial disbalance settings of first driving shaft, is installed on second driving shaft 12 can be rotated with respect to first driving shaft 6.Support second bearing 14 of second driving shaft 12 and the frictional force between second driving shaft 12 and provide power with respect to the rotation of second driving shaft 12 for second polishing base plate 22, second polishing base plate 22 has the trend of rotating with respect to second driving shaft 12, owing to be provided with flexible member 31 between housing 20 sharp second polishing base plate 22, the mutual balance of moment that moment of friction that second driving shaft 12 is subjected to and flexible member 31 are subjected to, thereby second polishing base plate 22 only can be rotated with respect to first driving shaft 6 with second driving shaft 12, and can not rotate with respect to second driving shaft 12.In the present embodiment, flexible member 31 comprises the bearing 32 that is arranged on polishing base plate 22 upper surfaces, by the fixing cutting ferrule 36 of bearing 32, be contained in the cutting ferrule 36 respectively the spring 38 and the steel ball 34 that match with polishing base plate 22 and boss 30.Whole elastic element 31 be fixed on the going up table of second polishing base plate 22 by screw and on.Be stained with the sand paper 24 of porous on the lower surface of second polishing base plate 22.When second polishing base plate 22 was installed, steel ball 34 radially was resisted against on the boss 30 with respect to second driving shaft 12 under the effect of spring 38.
Also be provided with four supporting components 25 on second polishing base plate 22, comprise the support spring 28 that is contained in the groove of offering on polishing base plate 22 upper surfaces and support steel ball 26, be used for the load on supplemental support second driving shaft 12.
Referring to accompanying drawing 3 and 4, in the second embodiment of the present invention, flexible member 31 forms by flexible material is folding, comprises horizontal folding limit 40 and vertical folded edge 39, and the horizontal folding limit 40 of flexible member 31 is fastened on the upper surface of second polishing base plate 22 by screw.When second polishing base plate 22 was installed, the vertical folded edge 39 of flexible member 31 radially was resisted against on the boss 30 with respect to second driving shaft 12.In the present embodiment, lower house 20 is provided with a plurality of boss 30 and matches with flexible member 31, a boss 30 also can only be set be used for matching with flexible member 31, limits second polishing base plate 22 freely rotating with respect to second driving shaft 12.Thereby second polishing base plate 22 is done regular orbital motion with respect to first driving shaft 6, polishing material in a small amount.
Shown in accompanying drawing 5 and 6, select to install first polishing base plate 21 among the present invention on second driving shaft 12 of sander.This polishing base plate 21 is a regular circular and since be provided with on first polishing base plate 21 with lower house 20 on flexible member 31, the first polishing base plate 21 that match of boss 30 can freely rotate with respect to second driving shaft 12, thereby polish relatively large material.
Thus, first polishing base plate 21 of the interchangeable installation different structure of same sander and second polishing base plate 22, thus realize two kinds of polishing function conversion.Be provided with on second polishing base plate 22 with housing 20 on boss 30 radially against flexible member 31, can need not to be provided with under the situation of special jockey, realizes second kind of function of polishing, easy to use, cost is low.Simultaneously, because flexible member 31 radially is resisted against on the housing 20, moment suffered during sander work is little, and flexible member 31 is not easy to lose efficacy, and has improved service life.
