  In order to manufacture the brush of the said patent documents 1, 2, and 4, all require the complicated process, The manufacturing cost was high. Moreover, although the brush of patent document 3 is comparatively easy to manufacture, since it is a cleaning brush, a required strength cannot be ensured, and it is difficult to apply it to a brush for processing such as deburring.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a processing brush that can reduce costs and can secure a predetermined strength by omitting complicated processing steps.

The invention according to claim 1 is a processing brush for performing processing such as grinding, polishing, surface treatment, cleaning, and deburring of a work surface, wherein the processing brush includes a pedestal , a channel brush, and the channel brush. the a fixing means for fixing to the pedestal, the channel brush, the brush pieces are formed by pinched by the strip only, or core wire and strip, there are formed in a spiral shape Only the both ends of the channel brush are attached to the pedestal by the fixing means so as to have a spiral continuous passage between the channel brushes, and the portions other than the both ends of the channel brush are attached to the pedestal. It is characterized by being slidable .

According to a second aspect of the present invention, there is provided a processing brush for performing processing such as grinding, polishing, surface treatment, cleaning, and deburring of a work surface, wherein the processing brush includes a pedestal, a channel brush, and the channel brush. The channel brush is formed in a spiral shape with the brush piece being sandwiched between only the belt-like body or the core wire and the belt-like body. Only about one circumference of the outer periphery of the channel brush is attached to the pedestal by the fixing means so as to have a spiral continuous passage between the channel brushes, and approximately 1 of the outer periphery of the channel brush. The portion other than the circumference is characterized in that there is a gap with the pedestal .

  In the invention of claim 1, since the channel brush is formed in a spiral shape, the channel brush has no joint. Therefore, the processing brush does not change its strength at the joint, can maintain a uniform and high strength, and has a high durability. Further, since the channel brush is formed in a spiral shape, the spiral shape can have elasticity, and the curvature of the R portion of the spiral shape can be arbitrarily set or changed. Further, since the processing brush has the spiral channel brush attached to the pedestal by the fixing means, a strong pressing force can be applied to the surface to be processed while maintaining the spiral shape. Therefore, high grinding power can be demonstrated. In addition, when the channel brush is formed in a spiral shape so that adjacent strips are in contact with each other, the strip is hardly deformed and can be pressed against the work surface while maintaining the spiral shape. Therefore, high durability can be demonstrated. Further, since the brush pieces are formed in a spiral shape, it is possible to prevent concentric brush marks from being attached to the rotation center of the processing brush. Therefore, there is no processing unevenness and a high grinding force can be maintained. Furthermore, since the channel brush is formed in a spiral shape, the brush pieces can sequentially contact with each other in an oblique direction with respect to the rotation direction of the processing brush, so that a high grinding force can be maintained and the removed flash or the like can be removed. It can be discharged outside without staying inside. In addition, since a processing brush having a multi-winding spiral brush piece can be manufactured instantly with a single channel brush, the processing cost can be greatly reduced.

In addition, since the processing brush has a spiral continuous passage between the channel brushes, when the processing brush is used in the same rotational direction as the spiral direction of the continuous passage from the outer peripheral portion toward the inner peripheral portion In, dust such as removed flash can be discharged out of the processing brush through the passage. Further, when the rotation direction is set in the direction opposite to the rotation direction, dust such as removed flash can be temporarily held in the passage. Furthermore, since the processing brush can temporarily hold cleaning water or cleaning oil in the continuous passage, smooth processing is possible, and dust such as removed flash can be prevented from reattaching to the processing surface. .

Moreover, since only the both ends of the channel brush are fixed to the pedestal, an intermediate portion other than the both ends can be slid, and an impact force can be absorbed to exhibit a high grinding force.

In the second aspect of the present invention, since only approximately one circumference of the outer periphery of the channel brush formed in a spiral shape is fixed to the pedestal, the inner periphery of the channel brush other than approximately one revolution is not processed during processing. Since the reaction force against the pressing force on the surface to be processed can be absorbed, high durability can be ensured.

  Next, embodiments of the present invention will be described with reference to the drawings. Fig.1 (a) is a front view which shows 1st Embodiment of this invention, FIG.1 (b) is AA sectional drawing of Fig.1 (a). As shown in this figure, the processing brush 1 has a channel brush 4 fixed to the upper surface of a substantially cylindrical pedestal 2 by a fixing means 3, and the brush 4a of the channel brush 4 has a core wire. One long channel brush 4 sandwiched between 4b and strip 4c is formed in a spiral shape, and then fixed to the upper surface of the base 2 by the fixing means 3. The channel brush 4 may be a brush composed of a brush piece 4a and a strip 4c that does not have a core wire 4b. Here, the fixing means 3 can be either a method of using a fixing tool or a method of joining. As an example of the case of using the fixing tool, a fastening (crimping), a rivet, a screw, a pin ( Stopping or press-fitting), hook-and-loop fasteners, cable ties, double-sided tape, etc. can be applied. Moreover, welding, adhesion, pressure bonding, or the like can be applied as a joining method. In the processing brush 1 of the present embodiment, welding is employed as the fixing means 3.

  As described above, the processing brush 1 has a single channel brush 4 formed in a spiral shape, and therefore the channel brush 4 has no joints. Therefore, the processing brush 1 does not change its strength at the joint, can maintain a uniform and high strength, and has a high durability. Further, since the channel brush 4 is formed in a spiral shape, the spiral shape can have elasticity, and the curvature of the R portion of the spiral shape can be arbitrarily set or changed. Further, since the spiral brush 1 is attached to the base 2 by the fixing means 3, the processing brush 1 can apply a strong pressing force to the surface to be processed while maintaining the spiral shape. Therefore, high grinding power can be demonstrated. Further, when the channel brush 4 is formed in a spiral shape so that the adjacent belt-like bodies 4c are in contact with each other, the belt-like body 4c is extremely difficult to deform and is pressed against the processing surface while maintaining the spiral shape. Because it can be used, high durability can be demonstrated. Further, since the brush piece 4a is formed in a spiral shape, it is possible to prevent concentric brush marks from being attached to the rotation center of the processing brush 1. Therefore, there is no processing unevenness and a high grinding force can be maintained. Furthermore, since the channel brush 4 is formed in a spiral shape, the brush pieces 4a can be brought into contact with each other in an oblique direction with respect to the rotational direction of the processing brush 1, so that a high grinding force can be maintained and removed. Etc. can be discharged to the outside without staying in the channel brush 4.

  FIG. 2 is a side view of the processing brush 1 of FIG. 1A viewed from the X direction. As shown in this figure, a scraping portion 5 for scraping the surface to be processed is formed at the end of the channel brush 4. Since the scraping portion 5 is formed so as to scrape dust such as flash on the surface to be processed in the rotation direction of the processing brush 1, the scraping portion 5 is firmly stuck on the surface to be processed. Garbage such as burrs can be peeled off.

  Fig.3 (a) is a front view which shows 2nd Embodiment of this invention, FIG.3 (b) is BB sectional drawing of Fig.3 (a). In the processing brush 11 of this embodiment, the channel brush 4 is attached to the spacer 7 by fixing means 13 and 33 so as to have a spiral continuous passage 6 between the channel brushes 4. The fixing means 23 is attached to the base 2. The spacer 7 is a substantially disc-shaped plate-like body made of metal, non-metal, or the like, and is provided with a spiral groove 9 for mounting the spiral channel brush 4 and in the circumferential direction. A plurality of radial holes 10 are formed. In the processing brush 11, after the channel brush 4 is mounted in the groove 9 of the spacer 7, the channel brush 4 and the spacer 7 are fixed by fixing means 13 by welding through the hole 10 from the lower surface of the spacer 7. The channel brush 4 is fixed to the spacer 7 from the upper surface of the spacer 7 by fixing means 33 by welding. The spacer 7 is fixed to the base 2 by fixing means 23 by welding. In this way, by providing the spiral continuous passage 6, the rotation direction of the processing brush 11 is set in the clockwise direction, so that dust such as removed flash can be removed through the continuous passage 6. Can be discharged to the outside. Further, when the rotation direction is set in the direction opposite to the rotation direction, dust such as removed flash can be temporarily held in the continuous passage 6. Furthermore, since the processing brush 11 can temporarily hold cleaning water or cleaning oil or the like in the continuous passage 6, smooth processing is possible, and dust such as removed flash can be reattached to the processing surface. Can be prevented.

  Fig.4 (a) is a front view which shows 3rd Embodiment of this invention, FIG.4 (b) is DD sectional drawing of Fig.4 (a). In the processing brush 71 of this embodiment, only both ends of the spiral channel brush 4 are fixed to the base 2 by fixing means 33 by welding. Therefore, at the time of processing using the processing brush 71, the intermediate portion other than both end portions of the channel brush 4 can slide, and the impact force from the processing surface can be absorbed and a high grinding force can be exhibited.

  Fig.5 (a) is a front view which shows 4th Embodiment of this invention, FIG.5 (b) is CC sectional drawing of Fig.5 (a). The processing brush 21 of this embodiment is attached to the pedestal 2 by the fixing means 3 at several locations in the range of approximately one circumference of the outer periphery of the channel brush 4 formed in a spiral shape. Further, the inner peripheral portion of the channel brush 4 is formed with a step with respect to the pedestal 2 so as to have an approximately mushroom shape. By configuring in this way, the inner peripheral portion of the channel brush 4 other than approximately one round can absorb the reaction force against the pressing force against the processing surface during processing, so that high durability and high grinding force are achieved. Can be secured.

  FIG. 6A is a cross-sectional view showing a fifth embodiment of the present invention, and FIG. 6B is a cross-sectional view showing a sixth embodiment of the present invention. The processing brush 31 shown in FIG. 6A is formed so that the end of the brush piece 14a constituting the channel brush 14 formed in a spiral shape protrudes in a spiral shape so as to become the spiral inner peripheral portion. The channel brush 14 is fixed to the base 2 by the fixing means 3. By adopting such a configuration, even if there is a step or unevenness on the surface to be processed, it is possible to perform uniform processing without remaining processing, and to secure a high grinding force. Further, like the processing brush 41 shown in FIG. 6 (b), the end of the brush piece 24a constituting the spirally formed channel brush 24 becomes so spiral that the end portion of the brush piece 24a becomes the spiral inner peripheral portion. The same effect can also be obtained by forming a hollow.

  FIG. 7A is a front view showing a seventh embodiment of the present invention, and FIG. 7B is a front view showing an eighth embodiment of the present invention. In the processing brush 51 shown in FIG. 7A, the outer peripheral shape of the channel brush 34 formed in a spiral shape is a hexagonal shape. Further, in the processing brush 61 shown in FIG. 7B, the outer peripheral shape of the channel brush 44 formed in a spiral shape is a star shape. By making the channel brushes 34 and 44 have such an outer peripheral shape, when the processing brushes 51 and 61 are rotated and come into contact with the processing surface, the beams or the like protruding on the processing surface are hexagonal. And a star-shaped outer peripheral projection can be efficiently removed, and a high grinding force can be maintained.

In addition, it cannot be overemphasized that various embodiment can be taken in the range which does not deviate from the meaning of this invention. For example, the scraping part 5 described in the first embodiment can be formed also in the other second to eighth embodiments.

  The brush of the present invention is used as various processing brushes used for cleaning, cleaning, grinding, coating and the like.
