The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Fig. 2 to Fig. 8, a kind of sanding apparatus that improves structure of the present invention, it comprises power set 4 and emery wheel 9, described power set 4 are provided with rotating shaft 5, described emery wheel 9 is abrasive discs 91 that center is provided with circular hole 92, and described rotating shaft 5 stretches in circular hole 92 and is fixedly connected with abrasive disc 91 by fixture.Also be provided with the power set 4 of rotating shaft 5, emery wheel 9 and fixture form agent structure of the present invention.
Described power set 4 are provided with rotating shaft 5, and after energising, rotating shaft 5 can High Rotation Speed.Described power set 4 are provided with safety switch 3, effectively control the switch of rotating shaft 5, guarantee handling safety.
Centered by described emery wheel 9, position is provided with the abrasive disc 91 of circular hole 92, and abrasive disc 91 of the present invention is generally by pottery, and resin or other conventional material of making emery wheel are made.
As main inventive point of the present invention, the interior distance between 93 of the outer 94 of described abrasive disc 91 and abrasive disc 91 is less than the diameter of circular hole 92, can keep the outer 94 of described abrasive disc 91 and the interior distance between 93 of abrasive disc 91 to be more than or equal to the radius of circular hole 92 simultaneously.Arrange like this, in terms of existing technologies, strengthened the diameter of circular hole 92, and dwindled the outer 94 of abrasive disc 91 and the interior distance between 93 of abrasive disc 91, when the present invention needs to change after using, its remaining material of institute is less, greatly increases operation rate.
The continuous renewal of making materials along with abrasive disc 91 changes, and as by pottery, resin substitutes traditional making material, and material cost is more and more higher, complies with scheme of the present invention emery wheel is set, and its cost of manufacture is few, and utilization rate is higher.
