Description

  The present invention relates to a composite roll brush composed of a plurality of roll brush members.

  Conventional roll brushes are used for polishing a workpiece because, when rotated at a high speed, friction at the contact portion between the brush bristles and the workpiece increases and the surface of the workpiece can be rubbed strongly. FIG. 6 shows a conventional roll brush 60. The roll brush 60 is a channel brush 3 in which a base portion of a plurality of bristles 1 is held by a channel member 2 and is fixed by being spirally wound around a cylindrical shaft body 4. The brush part 60a which consists of a plurality of brush bristles 1 is provided. The brush portion 60 a has a circular cross section perpendicular to the length direction of the shaft body 4. As another example, the conventional roll brush is an implanted brush provided such that a brush planting portion in which a bundle of a plurality of brush hairs is planted on a cylindrical shaft body 4 is scattered at an appropriate interval. There is a thing of the brush part which consists of.

  However, in the conventional roll brush, if the burr protruding on the surface of the work is firmly fixed to the work, the burr cannot be completely removed even if the high-speed rotation mode is set, and the contact friction with the work is excessive. The state may continue, and an appropriate rotation state corresponding to the high-speed rotation mode may not be obtained. In such a case, the roll brush may give an excessive load to the motor that rotates itself and may damage the motor. As described above, when the roll brush is used while being rotated at a high speed, it has been desired to improve the roll brush because care must be taken so that the contact friction with the workpiece does not become excessive.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and even if the workpiece is polished at a high speed, the contact state with the workpiece does not continue, and the composite roll can be used without excessive contact friction with the workpiece. The object is to provide a brush.

  In order to solve the above-mentioned problem, the invention according to claim 1 is composed of a plurality of roll brush members having a brush portion made of a plurality of brush hairs on a peripheral surface of a shaft body, and a pair of rotating disk members, Between the pair of disk members, shafts of the plurality of roll brush members are rotatably mounted, respectively, and a part of the outer peripheral surface of the brush portion extends outward from the outer edge of the disk member. The composite roll brush is mounted in parallel and at predetermined equal angular intervals.

  The invention according to claim 2 is the composite roll brush according to claim 1, wherein the brush portion of each roll brush member has a circular or polygonal cross section perpendicular to the length direction of the shaft body. It is.

  According to the present invention, when the composite roll brush is rotated at a high speed and the workpiece is polished, each roll brush member has an outer periphery of the brush portion that extends outward from the outer edge of the disk member each time it rotates a predetermined angle. Since the part of the surface is in contact with the workpiece and rotates, the workpiece is polished, so the contact state between the brush bristles and the workpiece is not continuous, and the contact friction is not excessive and the composite roll brush is driven. Damage to the means can be eliminated.

  Embodiments of the present invention will be described below with reference to the drawings.

  1A is a plan view showing Example 1 of a composite roll brush according to the present invention, FIG. 1B is a cross-sectional view taken along line AA of FIG. 1A, and FIG. It is a disassembled perspective view of the composite roll brush shown to a).

  1 (a), 1 (b), and 2, the composite roll brush 20 has a plurality of roll brush members 10 from which shafts 4 protrude from both ends, and a shaft 12 for each, and is rotated by driving a motor. And a pair of disk members 11a and 11b.

  Each roll brush member 10 has substantially the same structure as the conventional roll brush 60, and the channel brush 3 in which the base portions of the plurality of brush bristles 1 are held by the channel member 2 spirals to the cylindrical shaft body 4. It is wound around and fixed. Each roll brush member 10 is provided with a brush portion 10 a composed of a plurality of brush bristles 1 on the peripheral surface of the shaft body 4. The brush portion 10 a has a circular cross section perpendicular to the length direction of the shaft body 4.

  Each of the pair of disk members 11a and 11b has a shaft 12 protruding from the center of one surface of the disk substrate 11, and surrounds the shaft 12, and a plurality of holes 13 are provided at substantially equal distances from the center. They are provided at equiangular intervals.

  The composite roll brush 20 is assembled as follows. That is, the disk members 11a and 11b are arranged in a state in which the inner sides face each other and the respective shafts 12 protrude outward. In the composite roll brush 20, one end of the shaft body 4 protruding from both ends of the brush portion 10a of each roll brush member 10 is loosely fitted in each hole 13 of one disk member 11a. The end is loosely fitted in each hole 13 of the other disk member 11b, and the shaft bodies 4 of the plurality of roll brush members 10 are rotatably attached between the pair of disk members 11a and 11b.

  In the composite roll brush 20 assembled in this way, a plurality of roll brush members 10 are mounted equidistantly from the center in parallel and at a predetermined equiangular interval between a pair of disk members 11a and 11b that are disposed facing each other. The shafts 12 protrude outward from both ends of the pair of disk members 11a and 11b, and are integrated with a plurality of roll brush members 10 sandwiched between the disk members 11a and 11b. Each roll brush member 10 is mounted such that a part of the outer peripheral surface of the brush portion 10a extends outside the outer edges of the disk members 11a and 11b.

  The composite roll brush 20 rotates the pair of disk members 11a and 11b so that each brush portion 10a is brought into contact with the work (not shown), and when the work is polished, each disk member 11a and 11b is predetermined. Every time the rotation is performed, the brush portion 10a of each roll brush member 10 extending outward from the outer edge of each disk member 11a, 11b repeats the operation of polishing while contacting the workpiece and rotating.

  As described above, when the pair of disk members 11a and 11b rotate, the composite roll brush 20 comes into contact with the work each time a part of the outer peripheral surface of each brush portion 10a rotates by a predetermined angle. Therefore, the contact state between the brush bristles 1 and the workpiece is not continuous.

  Moreover, since both ends of the shaft body 4 are loosely fitted in the respective holes 13 of the disk members 11a and 11b, the roll brush member 10 rotates when it comes into contact with the workpiece. Is prevented from becoming excessive. The composite roll brush 20 adopts a three-dimensional moving mechanism in addition to a mechanism for rotating the composite roll brush 20 so that the composite roll brush 20 can be moved back and forth, left and right, and up and down while rotating. Deburring of different sizes and surface polishing of workpieces can be performed.
