Abstract

PURPOSE:To make it possible to reuse a cup shape brush with the replacement of brush filaments alone, by disposing the brush filaments in an annular space formed between the filament clamping surfaces of inner and outer holders to clamp the brush filaments therebetween. CONSTITUTION:When brush filaments 9 have been worn after polishing operation so that their free ends become ununiform, the width of an annular space 8 formed between the filament holding surfaces 2, 6 of inner and outer holders 1, 5 is increased by raising either the inner holder 1 or the outer holder 5. As a result, the pressing and clamping force to the brush filaments 9 disposed between the annular space 8 are released so that the filaments 9 fall in a freely dropping condition. Then, the free ends of the filaments 9 are uniformly aligned, and then the inner holder 1 is lowered again while the outer holder 5 is again raised so that the brush filaments 9 are pressed and clamped between the clamping surfaces 2, 6, thereby it is possible to further use the cup shape rotary brush for a polishing process.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention provides a deburring polisher and a rust removal line for removing burrs, burrs, etc. formed on the surface of a workpiece. The present invention relates to a cup-shaped rotating brush used for commercial purposes.

(Prior technology) Machines that remove burrs, burrs, etc. that occur when cutting and polishing aluminum alloy or cast iron parts, etc.
There is a deburring polishing machine that uses a cup-shaped rotating brush as shown in Japanese Utility Model Application Publication No. 60-178563, but conventionally,
As shown in FIG. 5, the cup-shaped rotary brush used in this type of deburring and sanding machine has the proximal end of the brush filament (39) densely planted in the upper metal fitting (31), and the brush body (32) The upper metal fitting (31) of this brush body (32) is connected to the main shaft of the deburr polishing machine on the upper surface using a disk-shaped shaft fitting (3) provided with a shaft (33).
The one fixed by welding to 4) is normal.

(Problem to be Solved by the Invention) For this reason, in the cup-shaped rotary brush as described above, the length of each brush filament (39) protruding from the lower surface of the upper metal fitting (31), that is, the length of the tip of the brush, is When it becomes short due to wear and becomes unusable, the shaft fitting (
34) must be discarded in its entirety, which is extremely uneconomical. Moreover, when the rotating brush is used for a long time, each brush filament (39) wears out, and the degree of wear varies depending on the location on the brush body (32).As a result, the tip of the brush body (32) The tips are not aligned and there are steps in various places, but since the brush filament L-(39) is densely planted, the length of the tips cannot be adjusted in some areas, resulting in uneven finishing quality of the workpiece. There is a problem with this.

(Means for Solving the Problems) The present invention relates to a cup-shaped rotating brush that solves the problems described above. An outer holder having a holder formed on the outer filament clamping surface is attached so that the gap width of the annular space formed between both filament clamping surfaces can be adjusted, and the brush filament filled in the annular space is pressed and clamped by both filament clamping surfaces. It is characterized by the fact that

(Function) Such a cup-shaped rotary brush expands the gap width of the annular space formed between the filament clamping surfaces of the inner holder and the outer holder when the wear of the tips due to polishing work has progressed beyond a specified level. Only the brush filaments that are filled and held in this area are dropped, replaced with new brush filaments, and inserted and filled into the annular space, and the tips of the brush filaments are aligned uniformly using a reference plate (not shown), and then, The width of the gap in the annular space is narrowed to press and hold the entire brush filament between the filament holding surfaces of the inner and outer holders. In addition, correction of the level difference due to unevenness of the tips of the brush tips can be performed using a reference plate or the like by adjusting the gap width of the annular space in the same manner as described above.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. In the first embodiment shown in FIGS. 1 and 2, (1) is an inner holder. The inner holder (11) has a flange-like locking part (3) stretched over the upper end of a hollow truncated conical part formed on the inner filament holding surface (2) whose outer peripheral surface is inclined in a widening shape. The locking part (3) has a thread formed on its outer periphery and a mounting shaft (
4) is standing. (5) is a cylindrical outer holder attached to the outside of the inner holder (1), and the inner peripheral surface of the lower part of the outer holder (5) is parallel to the filament holding surface (2) of the inner holder (1). The outer filament clamping surface (6) is a sloped surface that surrounds the outer periphery of the filament clamping surface (6). The upper part of the outer holder (5) has a straight cylindrical shape, and the inner surface thereof is formed with a locking part (η) having a screw that is screwed into the screw of the locking part (3). (8 ) are both filament clamping surfaces (

) and the outer holder (5) are rotated relative to each other and moved in the axial direction, thereby making it possible to adjust the gap width.

The structure configured in this way first has an annular space (8).
is filled with the specified brush filament (9), and with the tips of these brushes aligned in a line, turn the inner holder (1) or the outer holder (5) until the inner holder (
1) or raise the outer holder (5),
The gap width of the annular space (8) formed between both filament clamping surfaces (2) and (6) is narrowed, and the brush filament (9) located therebetween is pressed, and both filament clamping surfaces are (6) Since it is held in a fixed state between the shafts (6), such a cup-shaped rotating brush is attached to a deburring and polishing machine or the like via the shaft (4) to perform polishing work. However, if the brush filaments (9) are worn out due to the polishing work and their tips become uneven, reverse the above process by raising the inner holder (1) or lowering the outer holder (5) so that the annular space ( When the width of the gap 8) is widened, the brush filament (9) is no longer held and can fall freely. Then, the tips of the brush filaments (9) are aligned uniformly using a reference plate (not shown), and the inner holder (1) is lowered again or the outer holder (5) is raised to press and hold the brush filaments (9) as described above. and continue polishing.

Next, FIGS. 3 and 4 show another embodiment of the present invention, in which an inner holder (11) has a flange-like shape at the upper end of a short cylinder whose outer peripheral surface is an inner filament holding surface (12). The locking part (1
3) is stretched, and the locking part (13) has locking notches (13a), (13a) symmetrically formed, and a mounting shaft (14) is erected in the center of the top surface. It is set up.

Then, the filament clamping surface (1) of the inner holder (11)
2), an outer holder (15) surrounds the outer periphery of the inner filament holding surface (12) and is locked by a locking part (13) of the inner holder (11). 15) are two curved plates (15a) bent in an arc shape corresponding to the outer periphery of the filament holding surface (12).
) and (15b) are combined to form a cylinder, and a long hole (17) is formed in the outer curved plate body (15M) at each overlapping end.
A set screw (19) is installed at a position corresponding to the long hole (17) of the inner curved plate body (15b), and is screwed onto each bolt (19).
(20), the outer curved plate body (15a) and the inner curved plate body (15b) are connected to an integral cane, and the inner surface thereof is formed as a filament clamping surface (16). Further, support members (22), (22) are fixed to the outside of each curved plate body (15a), (15b) in symmetrical positions along the axial direction of the short cylinder body, and each support member (22) ) is the notch part (13a) of the locking part (13),
(13a) and tighten with nuts (23), (23
) is fixed. Then, the annular space (18) for filling and holding the brush filament (9) formed between the filament holding surfaces (12) and (16) can be opened by loosening each of the setting nuts (2G) or by loosening the curved plate body (15a). )
, (15b) in the normal direction while tightening the set nut (20), the gap width can be adjusted.

The device configured in this way is first a set nut (2

5b) in the normal direction to narrow the gap width of the annular space (1B)', and then tighten the set nut (20).

As a result, the brush filament (9) in the annular space (18) is pressed and clamped between the filament clamping surfaces (12) and (16) of the inner holder (11) and outer holder (15), so that is the support member (22), (
22) The upper end side is cut out (13a), (13a)
The brush filament (23) is inserted through the hole and tightened with a nut (23) to form an integral piece, and then attached to a deburring polisher etc. via the shaft (14) for polishing work. 9) is worn and the tips of the brush filaments are uneven, loosen the tightening nut (23) and set nut (20) to widen the gap width of the annular space (18), and the brush filament (9) will fall. Then, as in the case of the previous embodiment, align the tips on a reference plate (not shown), and again follow the same procedure as above to clamp the filament between the filament clamping surfaces (12) and (16) of the inner holder (11) and outer holder (15). The brush filament (9) is then tightened to the locking part (13) via the support members (22), (22) and fixed with the nuts (23), (23) during the polishing work. ) becomes unusable due to wear, replace the brush filament (9).
) should be replaced with a new one and held in the same manner as above.

(Effects of the Invention) As is clear from the above description, the present invention has been achieved by intervening the brush filament in a camp type rotating brush in the annular space formed between the filament clamping surfaces of the inner holder and the outer holder. Since only the brush filament can be attached and detached by adjusting the gap width of the annular space, even if the brush filament becomes unusable due to wear, it can be removed from the holder and integral structure of the conventional densely planted brush filament. It is extremely economical, as there is no need to dispose of the entire brush as in the case of the brush filament, and the brush filament can simply be replaced - simply reused.
Even if the tips of the tips are not aligned due to partial wear of the brush filament and a step occurs, the tips can be quickly aligned to a constant length by simple operation of the inner and outer holders, improving the quality of the finish on the workpiece. It is possible to measure the stability of Furthermore, since the inner holder and outer holder can be easily separated, changes in the gap width of the annular space and portion due to changes in brush filaments can be easily accommodated by changing the combination of the inner holder and outer holder. ,
This has many advantages for the user, such as the need to supply only the brush filament, resulting in lower costs, and it will greatly contribute to the development of the industry.
