FIG. 7 (A) is a longitudinal sectional view showing a conventional rotary grinding tool, and FIG. 7 (B) is a schematic sectional view showing the worn JK. Best form JBI Hereinafter, the embodiment JK of the present bleaching invention will be described with reference to the EI plane. FIGS. 1 and 2 show the embodiment of the rotary laboratory tool and the tool according to the present JM invention (first SI: FIG. 2 shows a schematic vertical cross-sectional view of the Kenmaroro material holding portion 11 and the center member 12 before engagement. FIG. An exploded perspective view of the member 2 and the central member 12 is shown.)

The substrate 1 is a circle 继 formed of a resin. By forming such a material, the substrate 1 is hardly deformed and has sufficient strength to perform rotary polishing. The reference numeral 1 is composed of a grinding member holding portion 11 and a center member 12 which are separately formed.

The polishing member holding portion 11 is a circle Jft provided with an annular body, that is, a hollow city 11 a. The polishing member 2 is attached to the surface 11 b of the polishing material holding portion 11 by an adhesive 22. Fixed,

And, on the inner peripheral surface of the hollow portion 11 a of the member holding member 11, an ant carving 11 d is formed as a rotation engagement portion.

Research »Tokyo 2 is made up of a large number of sandpaper pieces 2 ぃ” 21. Each of the sandpaper pieces 2 1-21 is 咪 a rectangular or almost fan-shaped piece _β here Sandpaper refers to not only paper with abrasive powder applied on the surface of paper, but also paper with abrasive powder applied on the surface of cloth.

The sandpaper pieces 21 of the sword * are arranged in a state 18 leaning against one of the sandpaper pieces 21 in contact with the ridge 18, that is, in a state 18 inclined with respect to the surface of the laboratory member holding portion 11, It is adhered to the Kenkei member holding part 1 1. The arrangement and the method of adhesion are free. For example, the surface where the adhesive 22 is applied 11b a number of sandpaper pieces 21 are arranged in a patch-like manner partially overlapped with each other. Then, while maintaining the state in which these pieces of sandpaper 2 1 are pressed against the material holding material 1 1, the adhesive 2 2 is dried ft.

The central member 12 is composed of a circular main body 12a, an insertion short portion 12b provided on the surface of the circular main body 12a, 1 2 c The disk body 1 2a is a circle having an outer diameter S that is smaller than the polishing material holding space 11 and is equal to or larger than the hollow space 11 a of the polishing material holding space 11.

At the center of the circle main body 12a, a rotary mounting hole 12e is formed as a joint. The rotary mounting hole 12e is a hole that penetrates the circle ffi substrate 12a. And a pulley or clutch plate that obtains rotational force indirectly from an electric motor or a Xiao Xun machine, and has an inner diameter that is approximately the same as the outer diameter of a rotating XY (not shown). The circular main body 12a is attached to the rotation shaft 11 by fitting the rotation mounting hole 12e into the rotation lux and fixing the rotation lux by appropriate means (not shown).

The insertion short tube 1 2b is a short tube diameter concentric with the disk main body 1 2a, and the outer surface of the housing 1 1a An engraved part 1 2 d that is S-engaged with d is formed as a rotationally engaging part,

»The shape 1 2c has the same or smaller outer diameter as the kenba-to-material holding portion 11;

The central member 12 formed in this way is used to grind the threaded portion 12 d of the short cylindrical portion 1 2 b for shaving. By engaging with each other, the insertion short tube 12b is detachably engaged with the hollow 11a of the polishing material holding device 11. That is, in such a case, the polishing member The holding part 11 and the central member 12 can be combined to form the substrate 1. The central member 12 is always fixed to the rotating shaft of a motor or the like, and the above-mentioned grinding is performed. The inner surface of the hollow part 11a of the material holding part 11a, that is, the base part 11d can be inserted if it is used for ordinary polishing. It is most preferable that the width in the insertion direction A (vertical direction in FIG. 1) of the short tube 12b is about 4 mm. However, such a usu can be changed as necessary. ,

For example, if the rotating shaft is clockwise, the knives 1 2d should not be loosened by the rotating tool, so that the rotating shaft does not come loose from the central member 12 due to the rotating shaft. , Right 41 [child is cut off, In this engaged state, the surface-shaped portion 12c of the central member 12 has its surface 12ca abutting against the rear surface 11c of the grinding member holding portion 11. Due to such abutment, the above-mentioned insertion rod does not penetrate into the hollow 11a of the member holding portion 11b. When f touches the surface 11 c of the polishing member holding portion 11, the force applied from the polishing member 2 to 時 during polishing is pushed back, and the shape of the polishing member 2 is maintained. Therefore, due to the presence of the »-shaped portion 12 c, the abrasive member holding portion 11 to be discarded together with the abrasive material 2 at the time of wear can be formed well.

Also, the surface 1 2 f of the »shaped part 1 2 c of Churo Lumber 1 2 and Ken! By forming irregularities on either or both of the back surface 11 c of the & member holding portion 11 1, the K-rubbing resistance between the two increases, and the β member holding portion 11 Engagement with the central member 1 and 2 becomes stronger.

_Β the explanation for the form »of the implementation of other than the above

The one shown in FIG. 3 (Α) is the same as the one shown in FIG. 1, and a substrate 10 composed of an integrally formed polishing member holding portion 13 and a rotating AX mounting portion 14; This is a rotary polishing tool formed with Kenroro 20 which was authored in Part 13.

In this embodiment, the Kenshiro material holding city 13 is a short cylindrical shape projecting to both sides of the center in the center instead of the hollow city 11a of the embodiment shown in 1B1). The short cylindrical part 13a is formed. The notched part 13d is formed on the JS surface inside the short cylindrical part 13a. The short cylindrical part 13a is used for holding the B member. It has a downward projection 13 e projecting below the back surface 13 c of the part 13. The mounting shaft 14 of the rotary shaft is the same as that of the embodiment shown in FIG. , A short tube part 14b for insertion, a capital 14c, and a mounting hole 14e for rotation, and an iJR engraved part 14d is projected on the outer surface of the short cylinder part 1b for insertion. In addition, unlike the one shown in Fig. 1, an outer groove 14g recessed below the »-shaped part 14c is formed on the outer periphery of the base of the short tube 14b for insertion.

Then, the moth carved portion 13 d and the moth carved portion 14 d meet. At this time, the downward projecting capital 13 e is accommodated in the concave groove 14 g. The thing shown in 3 EI (B) is the same as the thing shown in FIG. 1, and the polishing member holding part 16 and the rotating XY mounting part 17 which are formed separately It is a polishing tool formed by the lab beta material 18 bonded to the city material holding city 16.

In this embodiment », the polishing material holding portion 16 has a short cylindrical shape 16a protruding from both the shape and the same dimple as shown in FIG. The short cylindrical shape 16a has a downward projecting portion 16e projecting below the back surface 18c of the polishing member holding portion 16. However, in this embodiment, A 4¾ carved capital 16 d is formed on the outer J1 surface of the short cylindrical portion 16 a of the lower protruding part 16 e,

The rotating shaft mounting capital 17 is different from that shown in Fig. 1 and Fig. 3 (A), and is composed of a short cylindrical body 17a, »shaped capital 17c, and a rotating fe shaft mounting hole 17e. The short cylindrical body 17a is cast with an engraving 17d on the inner peripheral surface, and the engraved portion 16d and the flRSi 17d are merged.

Fig. 4 shows yet another embodiment JI8. In this embodiment 16), the polishing member 4 is formed by sandpaper pieces, unlike the above-mentioned embodiments] K. This is not a material, but a solidified β material with resin. The polishing member 4 thus formed has sufficient rigidity (independence) unlike the one shown in 1st EI. For this reason, it is not necessary to secure the strength to the surface of the polishing member holding portion 11 as described above. Therefore, in Embodiment 8, the substrate 1 is formed by the polishing member as described above. Without holding part,

In other words, the polishing member 4 is a circle having a hollow portion 4a at the center, and an engraved portion 4d is formed on the inner surface of the hollow portion 4a. More specifically, a hollow tube 4 d having a carved portion 4 d on the inner surface 151 is provided in the hollow city 4 a. The hollow tube 4 d is fixed to the J surface in the hollow 4 a. It is integrated with the member 4

And, in the rotary laboratory S tool, the central member 3 is the above-described substrate itself alone (because there is no need to wait for the aforementioned member »

The central member 12, which is a substrate, is the same as in Embodiment 18 in FIG. 1 and has the same diameter as that of Embodiment 18; a main body 3a; and a short insertion tube portion 3b provided on the surface of the disk body 3a; Extending sideways from the side green With a 锊 -shaped portion 3c,

In the embodiment of JBI shown in the fourth SI, in the JBI, the center member 3 is formed by cutting the cut portion 3 d of the short tube portion 3 b for insertion into the hollow portion 4 a of the grinding member 4. By engaging the moth with d, the input short cylindrical portion 3b is detachably engaged with the hollow portion 4a of the polishing member 4. That is, like this! By the combination, the substrate (center material 3) and the polishing material 4 are united, and both are detachable.

At the time of the above RR, the surface 3 f of the »-shaped portion 3 c comes into contact with the back surface 4 c of the polishing member 4. With such a configuration, the kenkei member 4 is as shown in FIG. Unlike sandpaper, even if it is formed of sandpaper, the strength (rigidity) required for polishing can be applied to the 锊 -shaped portion 3c without throwing the above-mentioned polishing material mounting member. It is also possible to implement as (not shown),

In the structure shown in FIG. 2, when the polishing material 4 is worn, only the polishing member 4 is discarded and a new one is engaged, and the substrate can be reused as it is. In addition, it is not necessary to remove the central member 3 serving as the substrate from the start of rotation of the Xiao Xing machine, etc.

In this embodiment I, the circular body 33 is more rounded than that of the embodiment of FIG. 1 in order to improve the safety during use, but is similar to that of FIG. May be the shape of

Further, another embodiment will be described. As shown in FIG. 5, as in the case of the above-mentioned 40th embodiment, the substrate does not have the above-mentioned arranging member holding means, and the central member 3 0 is the type that became the substrate itself.

As shown in the figure, the short circuit 30b for introducing the substrate has one of the rotation engaging portions, and projections 30d to 30d are formed on the outer J-plane m.

On the inner peripheral surface n of the hollow portion 40a of the polishing material 40, receiving grooves 40d to 40d are formed as the other rotation engaging portions. c! … 40 d is entirely open to the internal surface n. More specifically, the receiving surface 40 d to 40 d is the back surface 40 c side of the g member 40 (downward in FIG. 5). Upward (in the direction of arrow A in Figure 5) It has the introduced capital 40 e to 40 e formed and the holding capital 40 f 40 ί formed at the upper end of the introduction part 40 e to 40 e. The holding capital 40 f… 0 ί extends along the circumferential direction B of the inner circumferential surface n of the hollow portion 40a

In order to combine the polishing material 40 into the substrate (central member 30), insert the short cylindrical portion 30b into the hollow portion 40a of the polishing member 40. At this time, each protrusion 3 0 d '"30 d is inserted into the receiving groove 40 d-40 d introduction part 400 e from the ridge surface 40 of the ground material 40, and the receiving groove 4 0 t! ... Protrusion 30 (! ... 30 d force reached at 40 f 40 f holding the 40 d holding plate, the substrate (center member 30) is moved sideways with respect to the polishing member 40 As a result, the engagement is completed by rotating the projection 30 (Ρ · 30d) along the circumferential direction 上記 and moving it to the back of the holding portion 40 f (the left hand of the 511). ,

In this state, the substrate and the polishing material 40 are engaged with each other. The work of removing the polishing member 40 from the substrate may be performed in the reverse order of the above.

In FIG. 5, the projections 30 d and the receiving latencies 40 d are formed by 4 mm each, but the number can be changed as appropriate. In addition, the holding capacity 40 f of the receiving grooves 40 d is gradually increased. The protrusions 30 d may be securely held in the holding portion 40 f by holding the protrusions 30 d in the holding portion 40 f. Incidentally, such an engagement structure can be adopted also in the embodiment 8 shown in FIG.

Also, as shown in FIG. 1, even though the substrate is constituted by a separately formed polishing member holding member and a central member, the polishing member itself is constituted by a piece of sandpaper. Alternatively, it is also possible to use the same diagonal as shown in Fig. 5 and a resin with a sufficient strength formed by joining a grindstone to the resin.

Sections 6E) (A) and (B) show still another embodiment of the grinding member. | §6 EI (A) shows that the grinding member 41 is used instead of sandpaper. , A resin is mixed with an abrasive, and the whole is formed. The polishing surface K of the polishing member 41 has a lattice-shaped groove L formed thereon. Such a groove L is formed. As a result, the grinding ability is improved and effective. This is because the grindstone whose groove L has been polished and separated can escape from the workpiece S and the polished surface K. , FIG. 6 (B) shows that the polishing material 42 is made of the same dilute and sandpaper pieces as those shown in FIG. 1. However, in FIG. 6 (B) 1) is different from the one shown in FIG. 1 in that the abrasive member 42 is formed by laminating a plurality of annular (donut-like) sandpaper pieces 43 to 43. The reason is that when it is slightly worn, the sandpaper 21 on the front side can be removed and used.

Although not shown, the sandpaper pieces 4 3 to 4 3 are not formed in a donut shape. For example, the «JB body of a small-sized sandpaper is formed along the surface of the 3- However, the present invention can be implemented even if it is formed in an 81-shape and intermittently arranged. If formed in this way, as in the case shown in FIG. The grinding wheel can escape from the thrill of the β object to be polished and the β surface 研.

In the embodiment shown in FIGS. 6 (Α) and (Β), the substrate may be one in which the substrate lowers the polishing material holding node as in the case of FIG. 1, respectively. Similar to the case shown in FIG. 4, the substrate can be implemented by forming only the center member. In this case, especially in the case shown in FIG. 6 (6), the center member is disassembled on the side periphery. To support the laboratory members from above.

Also, the engagement means in each embodiment shown in FIG. 6 is based on the same structure as that shown in FIG. 1, or employs a structure other than the structure shown in FIG. Any of them can be implemented,

In any of the embodiments 5, the substrate can be formed of a cord material such as gold] R or ceramic, in addition to synthetic resin.

By implementing the first invention of this JO, when the polishing member of the image transfer polishing tool is worn out, it is not necessary to abandon the entire body with the polishing E9 material together with the polishing member, and a part of the body (Abrasive material holding city) can only be abandoned, reducing garbage and contributing to environmental preservation. In addition, the cost is reduced by reusing part of the main body. It also has a great effect in terms of savings *

In addition, when replacing worn rotating tools, the rotating shaft of a motor or the like is firmly attached as before. It is not necessary to search for the work of removing the entire rotary grinding tool that is fixed on the surface, and it is sufficient to remove only the polishing member holder that is removably engaged.

By carrying out the second invention of the present application, the effect of the first invention of the present application is obtained, and the strength necessary for polishing is secured, particularly when the polishing member is formed of a piece of sandpaper. A good effect was achieved in reducing the amount of material in the central member that was discarded together with it.

By implementing the third invention of the present BB, when the polishing material of the image polishing tool is worn, it is not necessary to abandon even a part of the main body on which the polishing material is thrown together with the member in charge of the grinding, and the dust is reduced. It is declining and has a great effect on environmental conservation. In addition, the entire body is reused, which has a further effect on cost savings.

Furthermore, when the worn rotary polishing tool is replaced, it is not necessary to remove the entire rotary polishing tool that is firmly fixed on the rotary tool such as an electric machine, as in the past. It is a simple operation to remove only the engaging members that are engaged.
