DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a side view of the present embodiment, FIG. 2 is a front view, and FIG. 3 is a rear view. For example, in a connecting portion 1b that is erected on both sides of one end of a plate-shaped portion 1a of a main plate 1 made of a steel plate, The connecting portions 2b that are erected on both sides of one end of the plate-shaped portion 2a of the slave plate 2 are connected to each other via the washer 3 by the connecting member 4
Are connected by. Here, a nylon material is used for the washer 3, and the connecting member 4 is strongly caulked, so that the slave plate 2 can be tilted in the direction C with respect to the main plate 1, and the tilted position is maintained. It is supposed to be done.

A rectangular guide hole 1c is provided in the plate-shaped portion 1a of the main plate 1 in the width direction. Two guide plates 5 having an L-shaped cross section are arranged on the front surface of the main plate 1, and these guide plates 5 are adjusted from the rear surface of the plate 1 by an adjusting screw 7 inserted into a guide hole 1c via a washer 6. They are screwed together so that the mutual width intervals can be adjusted.

The guide plate 5 has an abutting portion 5a that abuts against the main plate 1 and a guiding portion 5b that is vertically erected forward from the abutting portion 5a, and the guiding portions 5b are inside each other. Are arranged as follows. Two rollers 8 are rotatably supported on the outer side of the guide portion 5b by a support shaft 9 parallel to the contact portion 5a. Here, the front-back width of the guide portion 5b is made wider than the diameter of the roller 8.

On the other hand, the slave plate 2 is also made of a steel plate, for example, and the plate-like portion 2a is provided with a shaft hole 2c. A connecting shaft 10 is rotatably attached to the shaft hole 2c, a rotary driving means T such as an electric drill or an air tool is connected to the rear side of the connecting shaft 10, and a flap 11 as a rotary polishing means is connected to the front side. Are connected. Connecting shaft 10
A flap mounting hole 10a into which the mounting shaft 11a of the flap 11 is fitted is provided in the axis center of the.

The flap 11 is for polishing joints, and for example, a plurality of polishing sheets 11b such as paper files are used.
It is supposed to be radially attached to the tip of the attachment shaft 11a. The polishing sheet 11b has a flap outer diameter D in the free state and a flap inner diameter d in the narrowed state, and the flap inner diameter d is slightly smaller than the joint width.

The joint polishing member holder according to this embodiment having the above-described structure is used as an outer wall material A as shown in FIG. 4, for example.
When used for the joint B between, the rotation driving means T is first connected to the rear side of the connecting shaft 10, and the flap selected in accordance with the width of the joint B is inserted into the flap mounting hole 10a on the front side of the connecting shaft 10. The mounting shaft 11a of 11 is fitted. Next, the adjusting screws 7 are loosened and moved so that the guide plates 5 come into contact with the inner side surfaces of the joints B, respectively, and the adjusting screws 7 are tightened to fix the distance between the guide plates 5. In this way, with the rotation driving means T, the flap 11 and the guide plate 5 set as desired, the guide plate 5
Is inserted into the joint B, the roller 8 is pressed against the surface of the outer wall material A, and the inclination direction C of the follower plate 2 is adjusted so that the inclination of the flap 11 is optimum. At this time, the main plate 1 is stably held by the two rollers 8, and the slave plate 2 and the flap 11 are also stably held. When the main plate 1 is driven in the direction E by having the rotation driving means T and the rotation driving means T is driven, the polishing sheet 11b of the flap 11 is rotated to polish the inner surface of the joint B to a predetermined depth. A polishing portion F having a width is formed.

In the above-mentioned embodiment, since the guide plates 5 are provided so that the intervals can be adjusted, it is possible to easily cope with joints having different widths. On the other hand, the guide plate 5
May be integrally provided on the main plate 1 unadjustable, and in this case, one corresponding to the joint width may be prepared.

Further, since the sub-plate 2 is connected to the main plate 1 so that the inclination can be adjusted and the position can be held, the posture of the flap 11 can be easily corrected corresponding to the posture of the main plate 1. However, when the flap 11 is not affected by the posture of the main plate 1, the connecting shaft 10 may be held by the main plate 1 without providing the slave plate 2.

Further, since the flap 11 has a plurality of polishing sheets 11b mounted radially on the mounting shaft 11a,
When the joint width changes slightly, the outer diameter D changes and the joint can be evenly ground. However, the polishing sheet 11b
Instead of this, a rotary polishing member having a fixed outer diameter can be used. In this case, the polishing can be performed substantially evenly although the uniformity is slightly reduced.

The flap 11 has a diameter smaller than the joint width.
By using, it is possible to polish only one side surface of the joint B.

[0017]

As described above, in the joint polishing member holder according to the present invention, the guide member is inserted into the joint so as to contact the side surface of the joint, so that the movement of the rotary polishing means in the joint width direction is restricted. The side surface can be evenly polished. Further, since the guide member is provided with the rolling member, the holding member can be stabilized only by pressing the rolling member against the outer wall with a slight force, and the depth from the wall surface of the rotary polishing means can be maintained at a predetermined value. Further, since the rolling member rolls on the outer wall surface, the outer wall surface is not damaged and the labor can be reduced.
