The present invention relates to a device for burring a front face of a wheel. The device is composed of a rack, a motor, a guide rail, air cylinders, brushes and the like. A sensor enables the wheel to be positioned on a roller way, a clamping air cylinder drives left rolls and right rolls via synchronous gears and gear racks to clamp the wheel, a servo motor drives the wheel to rotate at relatively low speed under the clamped condition, and the rotation direction of the wheel is opposite to that of the brushes; the air cylinders I enable a dust cover to go down, and the motor drives a gear I and a central brush via a shaft II to rotate at relatively high speed; the gear I drives a gear II and a gear III to rotate simultaneously at slightly slow speed, so as to drive an outer ring brush to also rotate at relatively slow speed; and the air cylinders II drive the central brush and outer ring brush to go down, and burring can be performed once the central brush and outer ring brush contact the front face of the wheel. When in use, the device provided by the present invention can burr the central part and the spoke of the wheel at different rotation speeds, and the problem that the traditional big disc brush has low linear speed at the central position when rotating at fixed angular speed is avoided.

The present invention relates to a wheel brush, which is composed of a base plate, springs, chucks, iron sleeves and bristles. When a bristle unit is to be mounted, the iron sleeve of the bristle unit is placed on the upper side of the base plate, two anti-rotating lugs are made to correspond to two lug slots in the base plate, and the chuck is inserted from the lower side of the base plate; after a gasket is fixed in a counter bore in the lower side of the base plate, a wing nut is continuously pressed upwards, so that the spring is tensioned, and two guiding lugs of a fixing pin come into contact with the bottom ends of guiding slots in the iron sleeve; and after the wing nut is rotated by 90 degrees, the bristle unit can be locked.

The invention relates to a combined type wheel burr brush, consisting of a lower bottom plate, lantern rings, nylon brush units, an upper bottom plate, steel-wire brush units and the like, wherein the steel-wire brush units in II and IV areas are floating, and under a natural state, the height of the steel-wire brush units is 10 mm higher than that of the nylon brush units; when in work, the steel-wire brush units firstly contact a spoke of a back cavity of a wheel, burrs of the back cavity of the wheel can be removed powerfully when the steel-wire brush units rotate, the steel-wire brush units are continuously compressed, and when the nylon brush units also contact the spoke of the back cavity, burrs at corners can be smoothened; and when a small-size wheel is encountered, by removing the lower bottom plate, the fast locks and the lantern rings, a small-size burr brush can be formed. When the burr brush combining the steel-wire brush units with the nylon brush units of the invention is in use, not only can the efficiency of removing the burrs of the back cavity of the wheel be improved, but also the removing effect is very obvious, and meanwhile, the service life of the brush can be greatly prolonged.

An abrading apparatus for processing an edge of a tube is disclosed. The abrading apparatus includes a rotational symmetry axis and a chassis comprising an input side, an output side opposite the input side, and an input coupler on the input side of the chassis. The input coupler is coaxial with the rotational symmetry axis. The abrading apparatus also includes a centering member, coupled to the output side of the chassis and coaxial with the rotational symmetry axis, and abrasive members, coupled to the output side of the chassis. The abrasive members define an abrasive face radially spaced outwardly from and generally symmetric about the rotational symmetry axis and facing in a direction generally parallel to the rotational symmetry axis.

A tool for fine machining surfaces has a working medium carrier with a top face and a bottom face, wherein the bottom face is an attachment side. A set of individual exchangeable strip-shaped lamella holders are provided that each have one or more lamellas in individual or bundled arrangement. The lamellas each are oriented away from the attachment side of the working medium carrier and form in a downward direction remote from the attachment side a common working plane. The lamella holders on a side facing the attachment side are provided with first hooking members and the attachment side of working medium carrier is provided with second hooking members complementary to the first hooking members. The first and second hooking members are joined to each other in a direction perpendicular to the attachment side.

A selectively attachable buffer pad for using as an attachment to a conventional drill to buff or polish surfaces includes an attachment member which defines an elongated, rigid shank which is sized and shaped to be secured in the chuck of a conventional drill, a padded layer defining a planar body with a circular shape which is constructed out of a deformable material, and a buffer layer defining a conventional soft fiber buffing pad. Advantageously, the deformable nature of the padded layer enables selectively attachable buffer pad to transfer rotation from the attachment member to the buffer layer while also providing shock absorption. Thus, a conventional drill which is not otherwise suit for buffing or polishing is configured to accomplish the same through its attachment to the selectively attachable buffer pad.

A buffing pad having a front surface portion, a moisture barrier upon which the front surface is disposed, a compressible foam portion disposed below the moisture barrier, and a rear surface. The front surface portion has a plurality of indentations formed by RF welding and the rear surface has an attachment portion capable of attaching the buffing pad to a power tool. Methods of manufacturing and using a buffing pad.

The purpose of the present invention is to provide a device for brush-polishing by means of a polishing brush that rotates and revolves as in a planetary motion, wherein the conditions to polish can be easily set in accordance with the properties of the workpiece and the purposes to polish. A brush unit has a polishing brush that rotates and revolves. The brush unit includes a mechanism for driving the rotation that rotates the polishing brush and the mechanism for driving the revolution that revolves it. By adjusting the speed of the rotation by the mechanism for driving the rotation the capabilities to polish the workpiece are enhanced. By adjusting the speed of the revolution by the mechanism for driving the revolution the entire workpiece is uniformly polished.

A rotating tool (1) includes a tool body (5) including a polishing tool (2) and a shank (3), and a flange part (4) provided in the tool body (5). The polishing tool (2) includes a plurality of linear grinding members (6) and a grinding member holder (7) to hold the linear grinding members (6). The flange part (4) is an annular member (8), and attached to the grinding member holder (7) in a state of being movable in the direction of an axial line (L) and rotatable about the axial line (L). When the inner circumferential surface of a hole (H) formed in a workpiece (W) is processed, the grinding member holder (7) and the annular member (8) are inserted into the hole (H). When the run-out on the front side of the rotating tool (1) occurs, the annular member (8) comes into contact with the peripheral wall surface of the hole (H), whereby the run-out of the tool body (5) is reduced.

A polishing tool unit (1) includes a brush-shaped grinding stone (4) and a tool holder (2). The tool holder (2) includes a shank (2a), a sleeve (6), a gear screw (30), and a nut (36). The nut (36) is screwed onto a bolt portion (34) of the gear screw (30). The brush-shaped grinding stone (4) is connected to the front side of the nut (36) and held by the tool holder (2). The gear screw (30) is rotatable relative to the shank (2a) and the sleeve (6) about the axis (L). While rotation of the nut (36) about the axis (L) is regulated, the gear screw (30) is rotated, whereby the nut (36) is moved and the protruding amount of linear grinding members (3) is adjusted.
