A polishing apparatus comprising a disc-shaped polishing member, a substrate removably mounted on a table facing the outer periphery of the polishing member, and a receiver tiltably mounted on the substrate and having a desired inclined surface. The attachment is configured such that the pedestal faces the outer periphery of the polishing member in a tilted state in which the polishing member is retracted from the table, and can provide versatility to this type of polishing device. It is an attachment.

(Function) After the table is tilted so that the polishing member is retracted from the table together with the motor bracket, a pedestal having an inclined surface on the outer periphery of the polishing member is placed facing the pedestal, and the material to be polished is placed on the pedestal. The polishing work is performed by the rotating polishing member carrying the polishing member.

(Embodiments) Hereinafter, illustrated embodiments embodying the present invention will be described in detail.

First, to explain the polishing device G, reference numeral 1 refers to the table of the polishing device, which is formed from a substantially rectangular flat plate, and a rectangular opening 2, which is the actual polishing area, is inserted through the table approximately in the center of the table. has been done. A guide reference piece 3 having an angled cross section is provided on one side edge of the table 1 in the transverse direction.
one side of the table 1 through long holes 4, 4 penetrating through both side edges of the upper piece 3a and set screws 5, 5 screwed into the table 1 fitted into the long holes 4, 4. It is installed so that the distance between it and the edge can be adjusted. Note that the inside of the hanging piece 3b of the guide reference piece 3 is used as a reference surface, and a U-shaped escape groove is cut out in the upper piece 3a.

On the table 1, a forked bracket 6 is erected on the guide reference piece 3 side. A motor bracket 7 located along the side edge is supported via a pin 8 so as to be tiltable in a direction perpendicular to the guide reference piece 3, that is, in the directions of arrows P and Q in FIG. The motor bracket 7 is tilted approximately 130 degrees in the direction of the arrow Q until it comes into contact with the table 1, and in this state the polishing member, which will be described later, is positioned above the table 1.

A drive motor 9 is fixed to one side surface (left side in FIG. 1) of the motor bracket 7, and its main shaft 10 passes through the motor bracket 7 and projects to the other side surface (right side in FIG. 1). At one end, a disc-shaped polishing member 11 made of, for example, a grinding wheel is fitted and fixed by a pair of mounting flanges 12, 12 and bolts 13, 13. Incidentally, the polishing member 11 is positioned opposite to the opening 2 and in a direction perpendicular to the guide reference piece 3.

Thus, the polishing member 11 is moved in a direction perpendicular to the guide reference piece 3 along with the tilting of the motor bracket 7 at a portion facing the opening 3 of the table 1, that is, in a direction perpendicular to the guide reference piece 3, that is, in a direction opposite to the opening 3 of the table 1. It is tilted in a direction perpendicular to the direction of polishing movement with respect to the plane blade W attached to the plane (in the direction of arrows P and Q in FIG. 2).

A support protrusion 14 is formed on the end face of the motor bracket 7 opposite to the support portion, and a threaded portion of an adjustment screw 15 is screwed into the support protrusion 14. The screw portion of the adjusting screw 15 projects from the supporting protrusion 14 and comes into contact with the upper surface of the table 1, so that the vertical position of the polishing member 11 can be adjusted. Further, a spring 15a is provided at the upper end of the adjustment screw 15, and a spring 16 is elastically loaded between the flange 15b located almost at the bottom and the upper part of the support protrusion 14, and is screwed into the support protrusion 14. This prevents rattling in the threaded portion of the adjusting screw 15.

A grip member 17 for moving the polishing device G is erected on the other side edge of the table 1 in the lateral direction, and a grip member 18 is similarly protruded from the side surface of the guide reference piece 3. There is. In the figure, reference numeral 19 is a cover for the substantially semicircular polishing member 11 attached to the motor bracket 7, and reference numeral 20 is a motor cover for the drive motor 9, which is also attached to the motor bracket 7.

Further, on the table 1, the table 1
A mounting screw hole 21 for mounting an attachment, which will be described later, is provided at approximately the center of the longitudinal side edge of the portion facing the motor bracket 7 .

Next, the attachment of this example will be explained. As shown in FIG. Mounting bolt 24 to hanging piece 22a
A mounting hole 25 corresponding to the mounting screw hole 21 of the table 1 is provided through the horizontal piece 22b of the board 22, and the mounting hole 25, which corresponds to the mounting screw hole 21 of the table 1, is provided through the horizontal piece 22b of the board 22. With the polishing member 11 tilted in the direction of the arrow Q in FIG. 1 mounting screw hole 21 and the horizontal piece 22b of the board 22
The attachment is mounted on the table 1 by aligning the mounting holes 25 of the two and tightening and fixing them with mounting bolts 26.

This example is configured as described above, and its operation will be explained.

First, polishing of the plane blade W by the polishing device G will be explained. A plane blade W to be polished is attached to the knife stock N which has been removed from the plane bed (not shown), and the table 1 of the polishing device G is placed on the knife stock N with the plane blade W still attached. The reference surface inside the vertical piece 3b of the guide reference piece 3 is brought into contact with the knife stock N along the longitudinal side surface thereof. In this state, the plane blade W to be polished is positioned within the opening 2 of the table 1, and the plane blade W to be polished is guided to the table 1 so that the plane blade W to be polished is positioned approximately on the center line of the polishing member 11. The attachment of the reference piece 3 is adjusted via the setscrews 5, 5 and the elongated holes 4, 4.

Thereafter, the polishing member 11 is rotated by the driving of the drive motor 9, and the adjusting screw 15 is sequentially screwed back from the supporting protrusion 14 of the motor bracket 7, so that the motor bracket 7 is attached to the forked bracket 6. When the pin 7 is tilted in the direction of the arrow P in FIGS. 2 and 3 to bring it closer to the upper surface of the table 1, the polishing member 11 is moved downward together with the motor bracket 7 and brought closer to the upper surface of the table 1, thereby removing the plane of the knife stock N. Touches blade W. In this state,
The adjusting screw 15 is further screwed back and the polishing member 11 is further moved down to set the polishing allowance of the plane blade W to be polished. Then, by gripping both the grip members 17 and 18, the entire polishing device G is guided by the reference surface of the guide reference piece 3 that is in contact with the longitudinal side surface of the knife stock N. The plane blade W is moved by the polishing member 11 along the
It is used for polishing. In this case, since the motor bracket 7 is tiltably mounted via the pin 7 of the bifurcated bracket 6, the polishing member 11 is loaded with its own weight and the motor bracket 7 and drive motor 9.
Due to its own weight and the elasticity of the spring 16, the polishing member 11 is always urged downward;
In other words, it is pressed against the plane blade W to be polished, and the polishing is carried out smoothly without coming up during polishing.

As described above, the entire polishing device G is moved to the end of the knife stock N in the longitudinal direction, and the knife stock N is polished with the planer blade W attached to it. Leave the polishing device G. In this case, since the polishing member 11 is tiltably mounted to the forked bracket 6 together with the motor bracket 7 via the pin 8, the polishing member 11 is tilted in the opposite direction to the above-mentioned direction. You can also evacuate from there.

Next, a case where another material to be polished N is polished using the attachment will be described.

The table 1 is tilted together with the motor bracket 7 in the direction of arrow Q in FIG.
Evacuate from above (see Figure 6). In this state, the horizontal piece 22b of the substrate 22 constituting the attachment is placed on the table 1, and the upper end of the sloped surface of the pedestal 23 is opposed to the outer peripheral surface of the polishing member 11 at a predetermined distance. The pedestal 23
and the board 22 are firmly fixed with the mounting bolts 24, and then the mounting screw holes 21 of the table 1 and the mounting holes 25 of the horizontal piece 22b of the board 22 are aligned and fixed with the mounting bolts 26. (6th
In this case, since the pedestal 23 is tiltable with respect to the board 22 using the mounting bolt 24 as a fulcrum,
The angle of inclination of the inclined surface 23a can be set arbitrarily, and the gap between it and the outer peripheral surface of the polishing member 11 can also be set arbitrarily.

After the polishing member 11 is rotated by the driving of the drive motor 9, the workpiece M to be polished is placed on the inclined surface 23a of the pedestal 23 to perform the desired polishing process (see FIGS. 6 and 6). (see Figure 7), and is used as a so-called table-top all-purpose polishing device.

Note that the substrate 22 in the attachment of this example
The shape of the pedestal 23 is not limited to that shown in the drawings.

(Effects of the invention) According to the invention, as a plane blade polishing device, the plane blade to be polished can be polished smoothly and well while it is attached to the knife stock, so there is no need to remove the plane blade each time. This not only greatly reduces the time and effort required for the entire polishing process, but also allows the polishing member to be tilted and evacuated from the table surface, and the substrate and cradle with an inclined surface to be simply polished against the table. By simply mounting it facing the workpiece, this holder can be used to easily polish materials to be polished other than the plane blades mentioned above, making it versatile as a polishing device, not just for plane blades. It has the advantage of being able to achieve
