Description

[Detailed explanation of the idea] This invention is related to polyrasha.

Generally, when polishing a surface to be polished such as an automobile, wax is applied to finish the polishing afterwards, but it is cumbersome as polishing bodies such as brushes and pads must be replaced each time.

This idea was made in view of the above-mentioned points, and the purpose is to create a polisher that allows one-touch operation to use different polishing bodies depending on the purpose.

This invention provides a main body case with a rotating shaft connected to a driving part and an annular rotating body arranged around the rotating shaft, and a polishing body connected to each of the rotating body and the rotating shaft. and a switching device for holding the polishing body movably and fixedly in the axial direction on the rotating shaft so that both of the polishing bodies can be relatively moved and alternately come into contact with the surface to be polished. It is characterized by the fact that it has been provided.

Therefore, by operating the switching device, one of the different types of abrasive bodies can be selectively brought into contact with the surface to be polished.
It is constructed in such a way that it can eliminate the problem of 7.

An embodiment of this invention will be explained based on the drawings.

Reference numeral 1 is shown as a hemispherical main body case with a downward opening, and although it is not shown, it has a handle.

The main body case 1 is provided with a rotating shaft 3 connected to a motor 2 serving as a drive unit and extending downward, and a rotating body 4 held on the inner periphery of the main body case 1.

A gear 5 fixed to the rotating shaft 3 is attached to the main body case 1.
This gear 6 is meshed with the internal teeth 7 of the rotating body 4 .

The rotating body 4 holds finishing pads 8 which are a plurality of polishing bodies extending downward.

The rotating shaft 3 is provided with a switching device 10 that holds the pad 9, which is a polishing body, so as to be movable and fixed in the axial direction.

This switching device 10 includes a gear 1 fixed to the rotating shaft 3.
1, a cup-shaped gear 12 that accommodates the gear 11 and whose inner surface meshes with the gear 11; and a cup-shaped gear 12 that is rotatably held by the gear 12 to change the distance between the bottom of the gear 12 and the lower surface of the gear 11. It consists of a cam 13 that allows

Further, the gear 12 is urged upward by a spring 14.

The pad 9 has a wax storage section 15 with a lid (not shown) provided on the top surface thereof, and the bottom of the wax storage section 15 is filled with wax that penetrates into the outer pad layer 16 by capillary action or impregnating action. A wax supply layer 17 is formed.

In such a configuration, when the motor 2 is driven, the pad 9 rotates together with the switching device 10 and the finishing pad 8 rotates together with the rotating body 4.

At this time, the outside air flows from the through hole 18 to the exhaust hole 19 while cooling the motor 2.

Then, when the cam 13 is rotated to join the bipart to the lower surface of the gear 11, the gear 12 slides downward while bending the spring 14, and the pad 9 protrudes further toward the surface to be polished than the finishing pad 8.

That is, from the wax storage section 15 to the wax supply layer 17
Wax polishing is performed by supplying wax to the pad layer 16 through the pad.

When the bipart of the cam 13 is turned sideways, the gear 12 is moved by the spring 14.
The finishing pad 8 is retracted upward by the force of , and the finishing pad 8 protrudes toward the surface to be polished relative to the pad 9.

That is, finishing polishing is performed while wiping off the wax with the finishing pad 8.

At this time, if the pad 9 is covered with a cover (not shown) such as a resin sheet, dripping of the wax can be prevented even if liquid wax is used.

The pad 9 or the finishing pads 1 to 8 may be relatively moved manually or automatically using an electromagnet or the like.

In this case, an electromagnet or the like can be operated in a fixed cycle to alternately bring different types of pads into contact with the surface to be polished.

Further, as the drive unit, an air turbine connected to a vacuum cleaner, for example, may be used.Since this invention is constructed as described above, by operating the switching device, different types of polishing bodies can be selectively used on the surface to be polished. Therefore, it has the effect of eliminating the hassle of replacing and replacing the polishing body depending on the application.
