Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a brush head with a partition wall for grinding the surface of a steel material in order to remove burrs on a machined surface, weld slag from a welded area, and the like.

[Prior Art] Conventionally, a brush head with a partition wall for grinding the surface of a steel material is known. As shown in the plan view of FIG. 5 and the vertical sectional view of FIG. 6, the brush head with partition wall has eight central brush units 10.
, eight peripheral side brush units 20, and a circular flange 30 for fixing these.

A central partition wall 31 and a partition wall 32 are fixed to the circular flange 30 to separate and hold the central and peripheral brush units 10 and 20, and the flange portion 30 also engages with a drive shaft 90. Fitting part 91
A fitting hole 33 into which is fitted is provided, and a notch hole 34 into which a non-slip pawl 93 is fitted is further provided.

This central brush unit 10 uses a brush tuft 13 having a metal fitting 13K made by combining a large number of brush wires 13W, and a brush tuft 15 having a metal fitting 13K made by combining a large number of brush wires 15W together with a metal fitting 15K. , the side surfaces of the metal fitting 15K are connected at the welded part W shown in FIG. It is constructed by caulking 15N to a 15K metal fitting.

When attaching the central brush unit 10 to the flange 30, insert the bolt 15N into the bolt hole 30f of the flange 30, and then insert the bolt 15N into the bolt hole 30f of the flange 30.
I decided to tighten the 5N nut with a 15T nut.

The peripheral brush unit 20 basically has the same structure as the center brush unit 10. The peripheral brush unit 20 is also attached to the flange 30 with a similar structure.

[Problems to be solved by the invention] In the brush head with a partition wall configured in this way, the flange 3 is moved by the drive shaft 90 during grinding.
0 is rotated. Then, the tips 10H, 20H of the brush tufts are rotated and pressed perpendicularly to the surface of the steel material. At this time, brush tuft 1
Waist parts 13WE and 15WE, which are the intermediate parts of 0.20,
While bending, the 20WE cuts the outer partition wall 32 (32a, 32
It tilts in the direction of b) and is received here. Therefore, in the peripheral brush unit 20, there is less problem of the waist portion of the brush tuft breaking. However, in the case of the central brush unit 10 fixed to the center side of the flange 30, the brush tufts 13 and 15 do not have a partition wall that separates them in the radial direction, as shown in FIG. Therefore, during grinding, the waist portion 15WE of the brush tuft 15 on the radially inner side of the central brush unit 10 may be bent excessively.

That is, the conventional device described above cannot prevent excessive bending of the waist portion of all brush tufts.

By the way, in the conventional device shown in FIGS. 5 and 6,
When grinding steel materials, use brush tufts 13 and 15.
Waist part 13WE, 1 of brush wire 13W, 15W
5WE, etc., try to bend in the radial direction and in the opposite direction of rotation, and the waist portions 13WE, 15WE, etc. of the brush wires 13W, 15W bend against the partition wall 31, partition wall 3.
2 is accepted and supported. Therefore, the waist portion 13WE of the brush wires 13W and 15W,
Excessive bending such as in 15WE is suppressed, and the advantage is that it is suitable for accurate grinding. However, on the other hand, the waist portion 13 of the brush wires 13W and 15W
WE, 15WE, etc. frequently appear on partition walls 31 and 32.
In addition, since the partition walls 31 and 32 are touched with considerable force, they are worn out and worn out. In this case, it is not enough to simply replace the worn or worn partition walls 31 and 32. In other words, the entire flange 30 must be replaced with a new one, which is uneconomical. The reason is that brush wires 13W and 15W
This is because the partition walls 31 and 32 are fixed to the flange 30 for suppressing excessive bending of the waist portions 13WE, 15WE, etc.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to further improve the problem of bending at the waist of the brush tuft, and to prevent excessive bending of the waist of the brush wire. To provide a brush head with a partition wall which eliminates the uneconomical effects of replacing the entire flange when the flange decreases or wears out, and further improves the handling and storage properties of the brush unit.

[Means for solving the problem] The brush head with a partition wall of the present invention has a fan-shaped metal holding board, a brush wire at the tip, and the shaft end face is fixed to one side of the holding board. A plurality of brush tufts each having a plurality of brush tufts, a brush tuft partition wall that is held on a holding board and separates each radially adjacent brush tuft from each other in the radial direction, and a holding bolt that is held in a predetermined position on the other surface of the holding board. brush units having the same shape, a large number of fan-shaped mounting portions arranged in parallel in the circumferential direction of the central axis line, each having a fan shape that matches the fan shape of each holding board so that each holding board can be applied; A metal flange having a bolt mounting part that is provided at a position of the mounting part that aligns with the holding bolt of the brush unit and attaches the holding bolt, and a brush unit partition wall that separates each fan-shaped mounting part, The fan-shaped holding board is fixed to the inner peripheral edge, outer peripheral edge, and two opposing side edges of the holding board, and has a height lower than the tip of the brush tuft but more than two-thirds of the brush tuft, and has a height that is lower than the tip of the brush tuft, and has a height that is higher than the tip of the brush tuft. It is characterized by a sleeve-shaped peripheral wall that surrounds it from the sides and receives the brush wire during grinding.

That is, the brush head with a partition wall of the present invention has the following features:
It is constructed by attaching a large number of brush units each having a planar fan shape in alignment with each fan-shaped attachment portion of the flange.

Each brush unit includes a fan-shaped holding board, a plurality of brush tufts each having a brush wire at the end and whose shaft end face is fixed to one side of the holding board, and which are held by the holding board and arranged radially adjacent to each other. It has a brush tuft partition wall that partitions the brush tuft in the radial direction, and a holding bolt held at a predetermined position on the other surface of the holding substrate.

This brush tuft is a member that grinds the surface of the object to be ground with the tip of its brush wire. This brush wire is preferably a steel wire, but may also be a resin wire.
Further, the brush wires are bound together by welding, adhesive, caulking, or the like.

This holding board has a fan-like plate shape with a necessary wall thickness so that it can be efficiently disposed on the fan-shaped attachment part of the flange of the disc. These brush tufts and holding bolts are preferably fixed to this holding base plate by welding.

This flange is provided with a large number of fan-shaped mounting portions for holding a large number of brush units in isolation from each other. This fan-shaped attachment portion is provided to separate and hold each brush unit. Therefore, this fan-shaped mounting portion is partitioned into a fan shape by the brush unit partition wall so as to match the fan shape of the holding board of the brush unit. In this way, the planar shape of the holding board and the planar shape of the fan-shaped mounting part are the same, and as a result, there is no large degree of freedom when attaching the holding board to the fan-shaped mounting part, and therefore it can be easily positioned without any gaps. Can be installed together.
The fan-shaped attachment portion is provided with a bolt attachment portion at a position aligned with the retaining bolt of the brush unit.
The bolt attachment portion can be formed by a bolt insertion hole and a nut that is screwed onto the bolt passed through the bolt insertion hole.
The fan-shaped holding substrate has sleeve-shaped peripheral walls fixed to the inner peripheral edge, outer peripheral edge, and two opposing side edges of the holding substrate. The sleeve-shaped peripheral wall receives the brush wire during grinding, has a height lower than the tip of the brush tuft but more than two-thirds of the brush tuft, and surrounds each brush tuft from the outside. The height of the peripheral wall is preferably as high as possible without interfering with the function of the brush tuft during grinding.

[Function] When assembling the brush head with a partition wall of the present invention, the holding bolts of a large number of brush units are respectively attached to the bolt attachment portions of the flanges, thereby holding each brush unit to the fan-shaped attachment portion of the flange.

When grinding is performed using this brush head with a partition wall, the flange is rotated by a rotating device. During grinding, the brush wire of the brush tuft comes into contact with the object to be ground. At that time, this brush tuft is subjected to a radial acting force on its waist, but since the brush unit is provided with a brush tuft partition wall that partitions each brush unit in the radial direction, each brush tuft and brush tuft partition wall is reinforced or It is supported and its waist does not bend excessively. This increases the life of the entire brush tuft and thus the life of the partitioned brush head.

Further, since the sleeve-shaped peripheral wall surrounding the outside of the brush tuft is fixed to the inner peripheral edge, outer peripheral edge, and two opposing side edges of the holding substrate, the brush wires of the brush tuft can be protected.

[Example] Hereinafter, the brush head with a partition wall of the present invention will be described in detail based on a specific example.

(Configuration of the Embodiment) This brush head with a partition wall includes a brush unit 3 shown in the plan view of FIG. 1, and a flange 5 shown in the plan view of FIG. 3 and the vertical sectional view of FIG.
It is made up of.

First, the brush unit 3 will be explained. A plan view of this brush unit 3 is shown in FIG. 1, and a side view is shown in FIG. This brush unit 3 includes a fan-shaped holding board 3B made of a steel plate with a required wall thickness, arc-shaped brush tuft partition walls 3W and 3P fixed by welding to one flat side 3f of the holding board 3B, and a holding board 3B. 9 brush tufts 3T fixed by welding to one side 3F of the holding board 3B, and the other side 3 of the holding board 3B.
It consists of a bolt 3N as a holding bolt fixed to g by welding. As shown in FIG. 1, the brush tuft partition walls 3W and 3P are concentrically curved. The brush tuft partition walls 3W, 3P individually isolate the nine brush tufts 3T in the radial direction.

As shown in FIG. 1, a peripheral wall 14 is fixed to one side 3f of the holding board 3B in the form of a sleeve to the inner peripheral edge 3h and outer peripheral edge 3i, and to the two opposing side edges 3j and 3k. As shown in FIG. 2, the height of this peripheral wall 14 is lower than the tip of the brush tuft 3T, but is set to be at least two-thirds of the height of the brush tuft 3T. Therefore, as shown in FIG.
Most of the brush tuft 3T fixed to B (excluding the tip) is surrounded by a sleeve-shaped peripheral wall 14.

Next, the flange 5 will be explained. A plan view of this flange 5 is shown in FIG. 3, and a longitudinal cross-sectional view is shown in FIG. 4. The flange 5 includes a circular steel plate 5B having a required wall thickness,
Cylindrical brush unit partition walls 5W, 5P are provided by welding a steel plate to one side 5f of this steel plate 5B.
and eight radial brush unit partition walls 5.
It is composed of S. The area surrounded by the brush unit partition walls 5W, 5P and the brush unit partition wall 5S is a fan-shaped mounting portion 5Y in which each brush unit 3 can be individually accommodated. The fan shape of the fan-shaped attachment portion 5Y matches the planar shape (fan shape) of the brush unit 3, and has substantially the same shape.

Furthermore, in this embodiment, the circular steel plate 5B of the flange 5
is provided with a square hole 5H that fits into the tip of the drive shaft, and a notched hole 5N is provided near this square hole 5H. The notch hole 5N fits into a notch pin of a drive shaft that rotates the flange 5. Further, the steel plate 5B of the flange 5 is provided with 16 mounting holes 5D as bolt mounting portions through which the bolts 3N of the brush unit 3 are inserted. The mounting hole 5D is provided at a position that matches the bolt 3N of the brush unit 3. Therefore, the holding board 3B is attached to the fan-shaped mounting portion 5Y.
, the bolt 3N will almost naturally fit into the mounting hole 5D.

In this embodiment, the bolt 3N is inserted into the mounting hole 5D.
A large number of brush units 3 can be connected by inserting them into the
are fixed to the fan-shaped mounting portions 5Y of the flange 5, respectively.

The rotating device is driven with the partitioned brush head fixed to the drive shaft of the rotating device, and the flange 5 of the partitioned brush head rotates at a required speed. Then, the tip 3H of the brush tuft 3T is pressed perpendicularly to the surface of the steel material to be ground, thereby performing grinding.

(Effects of the Embodiment) As described above, according to the present embodiment, the brush tuft partition walls 3W, 3P are curved in the brush unit 3 that separates the brush tufts 3T in the radial direction.
has been established. Therefore, even if the waist of the brush wire 3E of the brush tuft 3T tries to bend in the radial direction and in the opposite direction of rotation during grinding, the waist is received, supported and reinforced by the brush tuft partition walls 3W and 3P. Therefore, excessive bending of the brush wires 3E of all the brush tufts 3T is eliminated. This point differs from the prior art in which excessive bending occurs in some brush tufts.

By the way, to perform brush grinding, use brush wire 3E.
There is a problem if the heights of the tips are uneven. In this regard, in this embodiment, as shown in FIG. 2, one shaft end surface 3Tb of a plurality of brush tufts 3T is
It is fixed against one surface 3f of. Therefore,
One surface 3f of the holding substrate 3B serves as a reference surface, and the other shaft end surface 3Ta of each brush tuft 3T can be made to have the same height. Therefore, the tip of each brush wire 3E can be made to have the same height. It is possible to avoid uneven heights of the tips of the brush wires 3E.

Further, in this embodiment, a method is adopted in which the bolt 3N is held at a predetermined position on the other surface 3g of the holding substrate 3B, which is the surface opposite to the brush tuft 3T. Here, the position of the bolt 3N can be arbitrarily set on the other surface 3g of the holding board 3B. Therefore, mounting hole 5
A design can be made in which the position of the bolt 3N can be easily aligned with the position D and the bolt 3N can be reliably inserted into the mounting hole 5D. Moreover, the other surface 3g of the holding board 3B
has a flat surface shape, and there are no particular restrictions, so the diameter of the bolt 3N can be set to a bolt diameter that provides the most suitable strength depending on the weight of the brush unit 3, etc.
Further, since the holding board 3B and the fan-shaped mounting part 5Y have fan shapes that match each other, by applying the holding board 3B to the fan-shaped mounting part 5Y, the bolts 3N can be automatically aligned with the mounting holes 5D, and the alignment , which makes alignment easier.

In addition, in this example, as described above, as shown in FIG.
h, outer peripheral edge 3i, two opposing side edges 3j, 3k
A sleeve-shaped peripheral wall 14 is fixed to the holder.
The height of this peripheral wall 14 is lower than the tip of the brush tuft 3T as shown in FIG.
It is set to two-thirds or more of the height of T. Therefore, as shown in FIG. 2, the brush tuft 3T fixed to the holding substrate 3B is surrounded by a high peripheral wall 14. Therefore, when storing or transporting the brush unit 3 removed from the flange 5 in the state shown in FIG.
4, which is advantageous in preventing the brush wire 3E of the brush tuft 3T from breaking or bending during storage and transportation.

By the way, when grinding a steel material, the waist portion of the brush wire 3E of the brush tuft 3T tends to bend in the radial direction and in the opposite direction of rotation, and the brush wire 3E
a peripheral wall 14 whose waist portion is sleeve-shaped, a partition wall 3W,
It is accepted and supported by 3P. Therefore, excessive bending of the waist portion of the brush wire 3E is suppressed, providing the advantage of being suitable for accurate grinding. However, on the other hand, since the waist of the brush wire 3E touches the sleeve-shaped peripheral wall 14, the partition walls 3W, 3P frequently and with considerable force, the sleeve-shaped peripheral wall 14, the partition walls 3W, 3P touch the sleeve-shaped peripheral wall 14, the partition walls 3W, 3P frequently and with considerable force. The 3P wears out and wears out. In extreme cases, holes may be made in the sleeve-shaped peripheral wall 14 and the partition walls 3W, 3P at the portions that are touched. In this regard, in this embodiment, the sleeve-shaped peripheral wall 14 of one of the brush units 3, the partition wall 3W,
If the brush unit 3P is abnormally worn or consumed, replacing only the abnormally worn or consumed brush unit 3 will remove the sleeve-shaped peripheral wall 14 and the partition walls 3W, 3.
P can also be replaced with a new one. Therefore, there is no need to replace the entire flange 5 with a new one.

[Other Embodiments] In the present embodiment described above, the brush unit 3 includes:
Brush tuft partition wall 3W made of curved plate material,
Although 3P is provided, the present invention is not limited to this, and a brush tuft partition wall having a mesh may be provided.

[Effects of the invention] According to the invention, all brush units are provided with brush tuft partition walls that separate radially adjacent brush tufts.
In all brush units, the waist portions of all brush tufts are not bent excessively. This point differs from the prior art in which excessive bending occurred in some brush tufts. Therefore, the life of all the brush units can be extended, and the life of the brush head with the partition wall can be extended.

Furthermore, in the present invention, before the brush unit is mounted on the flange, the shaft end surfaces of the plurality of brush tufts are fixed against one surface of the holding substrate. Therefore, when attaching the brush tufts to the holding substrate, one surface of the holding substrate serves as a positioning reference surface, and the other shaft end surfaces of each brush tuft can be made to have the same height. Therefore, the tips of the brush wires of each brush tuft can be made to have the same height, and unevenness in the heights of the tips of the brush wires of each brush tuft can be avoided, so that grinding can be performed accurately.

Further, the present invention employs a method in which the holding bolt is held at a predetermined position on the other surface of the holding substrate, which is the surface opposite to the brush tuft. Here, the position of the holding bolt can be arbitrarily set on the other surface of the holding board so that the position of the holding bolt is aligned with the bolt attachment part of the flange. Furthermore, the diameter of the holding bolt can be set to the most suitable diameter depending on the weight of the brush unit, etc.

Furthermore, in the present invention, since the holding board and the fan-shaped mounting part are fan-shaped so that they align with each other, by applying the holding board to the fan-shaped mounting part, the holding bolt and the bolt mounting part can be automatically aligned, making assembly easier. Make it easy.

In addition, in the present invention, a sleeve-shaped peripheral wall that surrounds most of the brush tuft is fixed to the holding substrate, so when the brush unit removed from the flange is stored or transported, the brush wires of the brush tuft can be easily removed. It can prevent bending, bending, and damage, and in this sense, it is suitable for precise grinding.

By the way, when grinding a steel material, the waist of the brush wire of the brush tuft tends to bend in the radial direction and in the opposite direction of rotation, and the waist of the brush wire is supported by the sleeve-shaped peripheral wall and partition wall. It is supported. Therefore, excessive bending of the waist portion of the brush wire is suppressed, providing the advantage of being suitable for accurate grinding. However, on the other hand, since the waist portion of the brush wire frequently touches the sleeve-shaped peripheral wall and partition wall with considerable force, the sleeve-shaped peripheral wall and partition wall in the touching portion are worn out and worn out. When the sleeve-shaped peripheral wall and partition wall are worn out and worn out in this way, the effect of the peripheral wall and partition wall, that is, the effect of suppressing bending of the waist of the brush wire, is reduced. Of the units,
a sleeve-shaped peripheral wall of a brush unit;
If the partition wall becomes abnormally worn or consumed, by replacing only the abnormally worn or consumed brush unit, the sleeve-shaped peripheral wall and the partition wall can also be replaced with new ones. Therefore, the uneconomical cost of replacing the entire flange with a new one can be avoided.
