Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is used for removing rust on the surface of an object to be polished, such as an automobile, for polishing the undercoat of paint, for peeling paint or for polishing the surface of a coating film. The present invention relates to a mechanical rotary brush, and particularly to a disk type rotary brush provided with a means for firmly attaching the synthetic resin fiber or the like to a rotary disk when the brush material is used.

(Prior Art) An industrial rotating brush is rotated and brought into contact with the surface of an object to be polished and relatively moved to remove rust on the surface of the object to be polished, peel off the coating, or polish the surface of the coating. It is used for a wide range of purposes. Therefore, there are various industrial rotary brushes in which the brush material to be used and its mounting shape are changed so that it can be applied according to the purpose of use such as the material of the object to be polished, its surface shape and the type of polishing.

For example, metal wire brush materials are used for removing rust from steel materials and peeling of paint films, and synthetic resin fibers and animal and vegetable fibers are used for surface cleaning and paint film surface polishing. Unless there are stripes, generally used as a wheel type brush in which a brush material is radially attached to the outer periphery of a rotating disk body, or as a roll type brush for supporting and rotating a large number of these in a polymerized manner, or It is often used as a cup type brush or a bevel type brush in which two large and small cup-shaped metal pieces are concentrically provided and a brush material is attached between these cups.

By the way, as a means for attaching the brush to the rotating disk body, when the brush material is a metal wire, a means of pinning or pinching the brush with a channel material is adopted, and when the brush material is a fiber wire. Has a large number of brush material implantation holes, and fiber fibers are implanted in the holes and fixed by pins or wires.

(Problems to be solved by the invention) There are two types of industrial rotary brushes that use a metal wire as a brush material and one that uses a fiber wire, as described above. Although attachment means have been adopted, they are still not sufficient and improvements are desired.

In particular, when attaching synthetic resin fibers as a brush material with an implanting means, there is a limit to the number of brush materials that can be fixed and held with an adhesive in the implant hole. The hole diameter cannot be increased,
For this reason, there is a problem that the brush material planted in the implantation hole causes hair collapse and uneven polishing due to rotation.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a disk-type rotary brush equipped with a means capable of integrally fixing and holding a large number of brush materials in a retaining shape as compared with the prior art. .

(Means for Solving the Problems) In order to achieve the above object, in the disk type rotary brush of the present invention, a rotating shaft having a hole diameter of 5 to 100 mm on the front side of the brush planting disk made of an appropriate material is used. At least two or more implant holes, which are penetratingly arranged inward in the axial direction at a tilt angle of 5 to 10 degrees, are equidistant from each other on the same circumference of a predetermined diameter centered on the axis of the disk. And a rotating disk having an expansion hole formed by expanding a predetermined depth from the back surface side at the rear end of each of the implantation holes, and detachably mounted on the back surface side of the rotation disk. It is a gist of the invention to provide a lid plate that can open and close each of the enlarged holes.

(Operation) In the disk type rotary brush configured as described above,
Since the implant hole for implanting the brush material is arranged through the inside of the axis of rotation with a tilt angle of 5 to 10 degrees, its use is combined with the action of the enlarged hole formed at the rear end of the implant hole. At this time, the brush material does not easily come off, and it is possible to suppress the density of the inside of the brush material from becoming small due to the collapse of the brush material due to the rotation, so that unevenness in polishing does not occur. Further, since the lid is detachably provided on the back side of the disc body, the implantation depth of the brush material to be planted in each of the implantation holes penetrating the disc body can be regulated by the lid body. You can
If the lid is removed after the brush is implanted, the adhesive can be directly pressure-filled into the enlarged hole of the implant hole, so that the adhesive is allowed to enter between the brush materials to integrally and firmly prevent slipping. Can be fixedly held.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Drawing FIG. 1 is a vertical sectional front view showing the structure of a disk-type rotary brush of the present invention, and FIG. 2 (a) and (b) are vertical sectional front views showing the shape of another embodiment of the enlarged hole of the implant hole, respectively. In the figure, reference numeral 1 is a disk for a disk-type rotary brush of the present invention, 2 is an implant hole provided in the disk 1, and 3 is a brush material implanted in the implant hole 2.

The disc 1 is formed of a proper material such as a synthetic resin material into a disc body or an annular plate body having a predetermined thickness, and the surface thereof has a hole diameter of 5 to 5 for implanting the brush material 3. Two or more 100 mm implant holes 2 on the same circumference with a predetermined diameter centering on the axis of rotation of the disk 1 at equal intervals, and tilt angles 5-10 inward in the direction of the axis of rotation. The through hole is provided with a certain degree of penetration, and an enlarged hole 2a is formed at the far end of the hole. The expansion hole 2a is formed by the adhesive 7 which is supplied and filled as described later.
Since the base end portion of the brush material 3 implanted in the body is integrally surrounded and solidified and held in a retaining state, the shape is not limited to that shown in FIG. 1 but FIG. B). Further, the implantation hole 2 and the enlarged hole 2a penetratingly arranged therein are not limited to being on the same circumference of the disc, and may be provided anywhere in the disc. For example, several pieces may be provided laterally and evenly on the diameter. Of course, several rows may be provided in parallel with the diameter of the disc.

Further, the disc 1 is provided with a shaft hole 4 in the center thereof, and the disc 1 is connected to and supported by a rotary shaft (not shown) of a pneumatic tool or an electric tool to rotate in the shaft hole 4. The rotary support shaft 5 is attached by appropriate means.

Further, 6 is a lid plate provided in the present invention, which is detachably provided on the back side of the disc 1 to open and close the enlarged hole 2a of the implantation hole 2 penetratingly arranged in the disc 1. In the embodiment, the attachment / detachment is performed by the rotation support shaft 5, but the lid plate 6 may be attached / detached independently.

Since the disc type rotary brush of the present invention is constructed as described above, when the brush material 3 is planted in the planting hole 2 penetratingly arranged in the disc 1, the planting hole 2 is formed by the cover plate 6. Expansion hole 2
By affixing the brush material 3 by closing the lower end of a, the implanting depth is made constant, and then the brush material 3 is bonded to the enlarged hole 2a of the implanting hole 2 except for the cover plate 6. The agent 7 can be directly pressure-filled from the back surface side. Therefore, at this time, since the adhesive 7 can be filled into the enlarged holes 2a while advancing between the brush materials 3 from the base end portion of the brush material group 3, if the adhesive 7 is solidified, the brush material group 3 is removed. It is possible to integrally and firmly fix and retain the retaining hole, and thereby, the diameter of the implanting hole can be made larger than that of the conventional one, and a larger number of brush materials can be implanted and retained.

(Effect of the Invention) In the present invention, as described above, the brush-implanting hole provided in the disk is penetratingly provided inward in the direction of the rotation axis with a tilt angle of 5 to 10 degrees, and an enlarged hole is formed at the rear end thereof. Since this can be opened and closed by the lid plate on the back side of the disk, the brush material is in an upright state due to centrifugal force when used, and has an angle of 5 to 10 degrees with the planting direction. The brush is less likely to come off, the polishing power is great, and the centrifugal force is less likely to spread. In addition, the adhesive can be directly pressurized and supplied from the lower end of the brush material with the brush material implanted in the implantation hole, which makes the implantation hole diameter larger than that of the conventional one and further increases the number of brushes. Since the material can be integrally and firmly held in the slip-out preventing state, uneven polishing caused by the collapse of the brush material due to the rotation is eliminated. Moreover, the brush material thus implanted can be taken out by means such as tapping from the top to the bottom after removing the lid plate, so that the disk can be reused.
