Abstract

In a brush-type processing device, a base portion of a processing brush is fixed to a reciprocating rotating shaft provided to a drive source. A brush portion extends from the base portion to one side along the radius of the reciprocating rotating shaft. When the reciprocating rotating shaft reciprocatingly rotates, a plurality of brush bristles of the brush portion reciprocatingly oscillates in a circumferential direction of the reciprocating rotating shaft. Accordingly, an object to be removed on a processed surface can be scraped off by allowing distal ends of the brush bristles to be pressed against the processed surface. In this case, the distal ends of the brush bristles that reciprocatingly oscillate repeatedly collide with the object to be removed from both sides in a reciprocating oscillation direction, thereby making it possible to effectively remove the object to be removed.

A processing brush comprising:

a base portion formed so as to be fixed to a reciprocating rotating shaft, the reciprocating rotating shaft being provided to a drive source and reciprocatingly rotating about an axis;
and
a brush portion that extends from the base portion to one side along a radius of the reciprocating rotating shaft and reciprocatingly oscillates in a circumferential direction of the reciprocating rotating shaft by the reciprocating rotation of the reciprocating rotating shaft;
wherein the base portion comprises:
a brush mounting portion fitted with a bottom of the brush portion;
and
a fixation portion extending from one end of the brush mounting portion to a side opposite to the brush portion,
the fixation portion is fixed to the reciprocating rotating shaft such that the brush mounting portion is formed along the reciprocating rotating shaft and the brush portion extends to a side opposite to the reciprocating rotating shaft through the brush mounting portion,
the base portion is formed by bending a long metal sheet material at an intermediate portion in a longitudinal direction,
one end side in the longitudinal direction of the metal sheet material from a bent potion serves as the fixation portion, and the other end side in the longitudinal direction of the metal sheet material from the bent portion serves as the brush mounting portion,
the brush portion includes brush bristles formed of nylon, and the brush bristles have a diameter in a range of 0.5 mm to 5 mm and a bristle length in a range of 5 mm to 200 mm, and
a rotation of the base portion relative to the reciprocating rotating shaft is regulated by allowing an engaged portion provided to the fixation portion to be engaged with an engaging portion provided to the reciprocating rotating shaft, and a mounting angle of the base portion with respect to the reciprocating rotating shaft is variable in a plurality of steps in the circumferential direction of the reciprocating rotating shaft.
