Problems solved by technology

In such a grinding brush, when the grinding brush is rotated during the grinding process, the front end portion of the linear abrasive material extending in the direction of the rotation center axis is expanded to the outer peripheral side due to centrifugal force, and the contact position of the linear abrasive material with respect to the workpiece becomes smaller. unstable

Embodiment 1

[0018] figure 1 It is a perspective view of the polishing brush of Example 1 of the present invention. figure 2 yes figure 1 exploded perspective view of the abrasive brush. image 3 (a) is a perspective view when viewing the abrasive material holder from above, image 3 (b) is a perspective view of the abrasive holder seen from below. Such as figure 1 As shown, the abrasive brush 1 in this example includes: a brush-shaped abrasive stone 12, which includes a plurality of abrasive material bundles 11 arranged in a ring; Material displacement limiting member 13 . The brush-shaped grinding stone 12 is detachably attached to the abrasive displacement restricting member 13 via a set screw 14 .

[0019] (brush grinding stone) such as figure 1 as well as figure 2 As shown, the brush-shaped grinding stone 12 includes an abrasive material holder 15 holding a base end portion (upper end portion) of each abrasive material bundle 11 . Each abrasive beam 11 protrudes downward fr...

Embodiment 2

[0051] Figure 6 It is a perspective view of the polishing brush 2 of Example 2 of the present invention. Figure 7 yes Figure 6 The exploded perspective view of the grinding brush 2. Such as Figure 6 As shown, the grinding brush 2 in this mode includes: a brush-shaped grinding stone 12, which includes a plurality of abrasive material beams 11 arranged in a ring shape; Material displacement limiting member 13 . The brush-shaped grindstone 12 is detachably attached to the abrasive displacement limiting member 13B by a set screw 14 . The brush-shaped grinding stone 12 of the grinding brush 2 of Example 2 and the brush-shaped grinding stone 12 of the grinding brush 2 of Example 1 are the same. In addition, since the polishing brush 2 of Example 2 has the structure corresponding to the polishing brush 1 of Example 1, the same code|symbol is given to a corresponding part, and the description is abbreviate|omitted.

Abstract

A polishing brush (1) includes a brush-shaped grindstone (12) holding grinding element bundles (11) of wire-shaped grinding elements (27) in an annular shape and a grinding element displacement-restricting member (13) for restricting displacement of the grinding element bundles (11) outward. The brush-shaped grindstone (12) has a grinding element holder (15) holding the base end portions (upper end portions) of the grinding element bundles (11). The grinding element displacement-restricting member (13) has an annular part (33) surrounding the wire-shaped grinding elements (27) from the outer peripheral side at a position between the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15) in the direction of the axis of center of rotation (L) and at a distance away from the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15). Since the portions on the side closer to the grinding element holder (15) of the grinding element bundles (11) held in the grinding element holder (15) are exposed outward, cutting fluid or air supplied from the outer peripheral side of the polishing brush (1) easily reaches the polished portion of a workpiece.

Description

technical field [0001] The present invention relates to a grinding brush, in which a plurality of linear grinding materials extend from a grinding material holder along the direction of the rotation center axis. Background technique [0002] There is known a cup-shaped polishing brush in which base ends of a plurality of linear abrasives arranged in a ring are held by an abrasive holder. In such a grinding brush, when the grinding brush is rotated during the grinding process, the front end portion of the linear abrasive material extending in the direction of the rotation center axis is expanded to the outer peripheral side due to centrifugal force, and the contact position of the linear abrasive material with respect to the workpiece becomes smaller. unstable. Therefore, in the grinding brush described in Patent Document 1, a skirt (cylindrical member) covering the outer peripheral side of the grinding holder side part of the abrasive material holder and the linear abrasive...
