Benefits of technology

This patent is about a polishing device that can automatically and effectively polish complex shapes, without causing uneven pressure or damage. The device has a mechanism that applies pressure to the polishing material, allowing it to expand and contract appropriately to make sliding contact with the surface being polished. This results in a uniform and efficient polishing process.

Problems solved by technology

In fact, the shape following ability of the elastic body is not particularly favorable.
Therefore, in the case where, for example, regarding a region-to-be-polished having a complex shape of the kind where a projection and a recess are alternately aligned, it is attempted to polish the projection of the region-to-be-polished, the elastic body may sometimes be insufficiently crushed.
However, this case is troublesome and a burden for the operator.

first embodiment

[0036]FIG. 1 is a schematic overall side view of a polishing device 10 according to a This polishing device 10 comprises: an articulated robot 12; a polishing mechanism 16 provided to a tip arm 14 configuring the articulated robot 12; and a control section 20 that controls the articulated robot 12 and the polishing mechanism 16. Note that the reference symbol 22 in FIG. 1 indicates a workpiece being an object-to-be-polished. An automobile body may be cited as a specific example of the workpiece 22.

[0037]The articulated robot 12 includes a rotatable pedestal 24 and a plurality of shaft sections 26, hence is capable of moving the polishing mechanism 16 to a certain place of the workpiece 22, and displacing the polishing mechanism 16 along a region-to-be-polished of the workpiece 22.

[0038]As shown in FIGS. 2 and 4, the polishing mechanism 16 is coupled to the tip arm 14 via a coupling plate 30. A gear holding plate 32 of narrower width and smaller area compared to the coupling plate 3...

second embodiment

[0089]For example, in the second embodiment, the first coil spring 192 and the second coil spring 194 are adopted as the tension applying unit. However, a cylinder may be adopted instead.

[0090]Moreover, instead of the polishing mechanism 16, the polishing mechanism 150 may be arranged in the endless belt 70 to configure the polishing device 10.

[0091]Furthermore, polishing may be performed similarly to above except that the motor for eccentric rotation 34 is not operated (in other words, except that the polishing mechanism 16 is not eccentrically rotated). Also in this case, sufficient polishing is performed. As may be understood from this, the eccentric rotation unit, such as the motor for eccentric rotation 34, is not indispensable.

[0092]Further still, adjacent pressing force applying mechanisms 90 (or pressing force applying mechanisms 159) may be supported by the supporting body 60 (or the supporting body 152) in such a manner that the phases of the swinging covers 110 (or swingi...

Abstract

A polishing device is provided with an expandable or contractible polishing body. The polishing device is further provided with a polishing mechanism that includes: a pressing force applying mechanism that applies a pressing force to the polishing body; and a supporting body that supports the pressing force applying mechanism. Moreover, the pressing force applying mechanism is configured to include an advancing or retracting section capable of advancing or retracting, and a swinging section provided in a swingable manner to a tip of the advancing or retracting section, the tip facing the polishing body.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2018-194182 filed on Oct. 15, 2018, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a polishing device that polishes an object-to-be-polished by a polishing body.Description of the Related Art[0003]A polishing body for polishing an object-to-be-polished is usually configured as a disk-shaped rotating body as exemplified in Japanese Laid-Open Patent Publication No. 2004-009189. However, in this case, although it is possible for a flat surface to be polished, it is not easy for an irregular surface where undulations are present to be uniformly polished.[0004]Accordingly, providing the polishing body with an elastic body (a cushion), for example, a sponge, is envisioned. This is because in this case, the elastic body is crushed when polishing a...
