A wheel deburring device. A motor II drives an upper brush to rotate, cylinders II enable the upper brush to fall through posts III, and burrs of a front surface can be removed when the upper brush is in contact with the front surface of a wheel; a motor I enables an outer ring and a geared ring I to rotate through a belt I; a motor III enables an inner ring and a geared ring II to rotate through a belt II, directions of rotation of the inner ring and the geared ring II are opposite to that of the outer ring, and brushes are driven to rotate through a gear; and cylinders IV enable a lower brush to rise through guide posts I, and burrs of a back cavity of the wheel can be removed when the lower brush is in contact with that back cavity.

A polishing pad conditioning apparatus includes a base, a fiber, and a polymer protruding from a surface of the base and encompassing the fiber.

A polishing device for polishing bristles includes a grinding surface and a friction material thereon, the friction material having aramid fibers or pulp bonded with a polyimide resin.

A segment for detachably arranging on a carrier, which can be rotatably mounted relative to an axis of rotation, for forming a disc brush or for forming a cleaning, grinding or polishing disc, includes a segment body, wherein multiple bristles protrude from the underside thereof or an abrasive grit and/or a fiber structure is arranged on the underside thereof, wherein the segment body has a segment guide extending in the radial direction in relation to the axis of rotation of the carrier on a radially internal edge and spaced apart from an external—in relation to a circumferential direction—lateral edge of the segment body, which segment guide is designed to cooperate with a corresponding carrier guide formed or arranged on the carrier for arranging the segment on the carrier.

A polishing pad conditioning apparatus includes a base, a fiber, and a polymer protruding from a surface of the base and encompassing the fiber.

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.

A polishing brush (4) includes a grinding element bundle (9) formed with a plurality of wire-shaped grinding elements (28) formed by impregnating and solidifying an assembly of inorganic filaments with resin, and a grinding element holder (7) having a holding hole (20) holding the base end portion of the grinding element bundle 9 on an outer peripheral side surface (7c) serving as a grinding element-holding surface. The grinding element bundle (9) has a front surface (9a) facing forward in a rotational direction (R1) and a back surface (9b) facing backward. The grinding element bundle (9) is held in the grinding element holder (7) such that the front surface (9a) and the back surface (9b) are inclined in the same direction relative to a virtual surface (30) that includes a center point (P) of a cross section (9d) of the grinding element bundle (9) cut across an outer peripheral side surface (7c) and the axis of center of rotation (L) of the grinding element holder (7) and extends in a radial direction. The wire-shaped grinding elements (28) included in the grinding element bundle (9) are easily displaced and can release excessive force applied thereto.

A polishing apparatus is provided with a machining head that is supported to freely move in two horizontal directions; driving devices that enables the machining head to move; a polishing jig that is supported by the machining head to freely move in a vertical direction; a polishing member that is mounted on a lower end portion of the polishing jig; an air cylinder polishing jig moving device that moves the polishing jig and is capable of pressing the polishing member against a tube support plate; and a drive motor that is capable of rotating the polishing jig, thus, simplification of the structure is made possible.

The present invention provides an improved online burr removing device for a wheel. When the device is used, equal rotating speeds of the inner brush and the outer brush can be realized by using one driving motor, thereby avoiding the problem that the linear speed is low in the center but high at the outer edge when an integrated brush rotates at the same angle; meanwhile, the device has the characteristics of high automation degree, advanced process, simple structure and high safety and stability.

The brushing device contains a bundle of fibre rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fibre rods. Once fibre rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fibre rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fibre rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).
