BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0008]
As shown in FIG. 3, the laminated rotary polishing tool A is configured by laminating a plurality of elastic polishing disks 1, and each elastic polishing disk 1 is thin, flexible, hard to break, and stiff.
[0009]
As shown in FIG. 1, the elastic polishing disc 1 has a resin layer 3 formed on the surface of a single circular base material 2 made of inorganic fiber cloth, and abrasive grains (not shown) are attached to the resin layer 3. It is configured. The production of the elastic polishing disk 1 is performed by impregnating the inorganic fiber cloth with a resin and drying the resin, cutting out a circular base material 2 from the inorganic fiber cloth, applying the resin on the surface of the base material 2, and forming a resin layer. 3 is formed, and abrasive grains are attached to the resin layer 3. A mounting hole 4 is provided in the center of the elastic polishing disk 1, and a concave portion 5 is formed in the center of the elastic polishing disk 1 so that the lower surface is bent.
[0010]
The method of manufacturing the elastic polishing disk 1 is not particularly limited. For example, a circular base material 2 having a central hole is cut out from an inorganic fiber cloth, and the base material 2 is impregnated with a resin containing abrasive grains. It can be obtained by molding so as to protrude upward. Further, as the inorganic fiber cloth, a glass fiber cloth, a carbon fiber cloth, or the like, which is easily worn, is used.
[0011]
Examples of the weaving method of the inorganic fiber cloth include plain weave, twill weave, and satin, but are not particularly limited. The impregnated resin is a thermosetting resin such as an epoxy resin, a phenol resin, and an unsaturated polyester resin. The viscosity of the impregnated resin is set to a size that does not block the mesh openings of the base material 4.
[0012]
As shown in FIGS. 2 and 3, when the laminated rotary abrasive tool A is used by being attached to the rotating shaft B1 of a grinder B, a plurality of elastic polishing disks 1 are overlapped and the upper and lower elastic polishing disks 1 are stacked. The rotating shaft B1 is inserted into the mounting hole 4 of the elastic polishing disk 1 in a state independent of each other without being bonded with an adhesive or the like. Then, the screw hole B3 of the lower flange B2 of the grinder B is screwed into the screw portion B4 of the rotary shaft B1, and the laminated rotary polishing tool A is held between the upper flange B5 and the lower flange B2 fixed to the rotary shaft B1. . The lower flange B2 is accommodated in the concave portion 5 of the lowermost elastic polishing disk 1, and a reinforcing pad C is provided on the upper surface side of the uppermost elastic polishing disk 1.
[0013]
In the laminated rotary polishing tool A constructed by laminating the elastic polishing disks 1, the elastic polishing disks 1 are not bonded to each other and are independent from each other. The characteristics of the elastic polishing disk 1 are not impaired. Therefore, as shown in FIG. 4, it can be adapted to the surface to be ground of the work material D, and good polishing performance can be exhibited. In addition, the performance of alleviating the impact force when hitting the work D is also improved.
[0014]
When the lowermost elastic polishing disc 1 (1A) of the elastic polishing discs 1 of the laminated rotary polishing tool A becomes worn and needs to be replaced, the lower flange B2 is removed and the rotating shaft B1 of the grinder B is removed. After removing the laminated rotary polishing tool, as shown in FIG. 3, the elastic polishing disk 1 (1A) is removed, and a new elastic polishing disk 1 (1B) is laminated on the uppermost stage of the laminated rotary polishing tool. refill. When replacing a plurality of worn lower elastic polishing disks 1 including the lowermost elastic polishing disk 1 (1A), the same number of elastic polishing disks 1 are replenished.
[0015]
Further, since the number of elastic polishing disks 1 of the lamination type rotary polishing tool A can be freely set, the elastic polishing disks 1 can be properly used according to the use or the like. In other words, when the polishing performance is determined based on the followability (flexibility), elasticity, and grinding force of the work material D on the uneven surface, the flexibility is improved as the number of laminations decreases, but the elasticity and the grinding force are reduced. Power drops. Conversely, the greater the number of layers, the lower the flexibility, but the better the elasticity and grinding power. In addition, if the grinding of the workpiece D is flat, but the grinding is not desired, the number of sheets needs to be reduced. Furthermore, it is necessary to adjust the number of elastic polishing disks 1 according to the material of the work material D (steel, aluminum, stainless steel, FRP, etc.). It can be used according to surface polishing and the like.
[0016]
For example, in the case of polishing the surface of a work material D made of aluminum, high polishing performance can be obtained by using a laminated rotary polishing tool A in which two elastic polishing disks 1 each having a thickness of 1 mm and an outer diameter of 100 mm are laminated. Is obtained.
[0017]
【The invention's effect】
According to the lamination type rotary polishing tool of the present invention, the elastic polishing disks formed by attaching the abrasive grains with the resin to the surface of the fiber cloth base material impregnated with the resin are laminated without being bonded to each other. It is possible to obtain high polishing performance by preventing the elastic polishing disks from being restrained from each other and deteriorating the characteristics of the elastic polishing disks, and to freely set the number of elastic polishing disks in the laminated rotary polishing tool. Therefore, it can be used properly according to the use or the like, the workability is improved, the performance of reducing the impact force is enhanced, and the vibration transmitted to the worker can be reduced.
[0018]
According to the method of using the laminated rotary polishing tool of the present invention, the laminated rotary polishing tool is detachably attached to the rotating shaft of a grinder, and the elastic polishing disc located below the laminated rotary polishing tool has worn. Sometimes, the elastic polishing disk is removed, and a new elastic polishing disk is stacked and replenished on the upper side of the lamination type rotary polishing tool.
