Disclosed is a deburring device for a back cavity of a wheel, composed of a machine frame, a clamping and rotating system, a rising and falling translation system and brush units. Jaws clamp a wheel on a roller way, upper cylinders enable the wheel to rise through four upper guide posts, and a first servo motor enables the wheel to move to upsides of conical sleeves through a second gear rack and a second gear; the upper cylinders enable the wheel to fall, and outer sides of the four jaws are in fit with the conical sleeves; a second motor enables the wheel to rotate in a clamped state; a first motor drives a bottom plate and a brush system to rotate in a circumferential direction through a first synchronizing belt; a second servo motor drives a first brush to rotate, a third servo motor drives a second brush to rotate, and brush hairs of the two brushes apply brushing forces of different directions to a back cavity of the wheel; a direction of rotation of the wheel is opposite to that of the brush system; and lower cylinders enable the brush system to rise through lower guide posts, and the brush system can carry out deburring when the brush system is in contact with the back cavity of the wheel.

The present invention provides a wheel deburring device, consisting of a frame, a motor, a guide rail, a swing plate, a cylinder, a servo electric cylinder and a hairbrush and the like. When in use, the device provided by the present invention can adjust the angle of the hairbrush according to the shape of the back cavity of the wheel spoke to adapt to hubs of any style, and the deburring effect is very ideal; and meanwhile, the device has the characteristics of high degree of automation, advanced process, safe and stable performance, etc.

An apparatus (10) for machining a workpiece (12) comprises at least two machining elements (14a, 14b) and a rotating belt (16) for moving the machining elements (14a, 14b) relative to a workpiece (12) to be machined. The machining elements (14a, 14b) each comprise a main body (20a, 20b) and a first connecting element (22a, 22b) connected to the main body (20a, 20b), which first connecting element is connectable to a second connecting element (24a, 24b) complementary to the first connecting element (22a, 22b) and connected to the belt (16). The first connecting element (22a, 22b) comprises a rotary body (26a, 26b). The second connecting element (24a, 24b) has a connection area (28a, 28b) for connection with the rotary body (26a, 26b). When the rotary body (26a, 26b) is rotated in a first rotary direction (R1) the rotary body (26a, 26b) is connected to the connection area (28a, 28b). When the rotary body (26a, 26b) is rotated in a second rotary direction (R2) opposed to the first rotary direction (R1) the rotary body (26a, 26b) is separated from the connection area (28a, 28b). The rotary body (26a, 26b) is arranged relative to the main body (20a, 20b) and connected to the latter in such a manner that during machining of the workpiece (12) a resulting force is exerted on the rotary body (26a, 26b) via the main body (20a, 20b), which force provides a torque for a rotation of the rotary body (26a, 26b) in the first rotary direction (R1).

An engine valve having a shaft portion and a head portion expanding in diameter like a head at an edge of the shaft portion, and being to open and close a port provided in a cylinder head, wherein the head portion has a head front surface on a bottom side facing a combustion chamber side, a head rear surface on a top side facing the port side, and an outer peripheral surface of the head portion formed between the head front surface and the head rear surface, and the head portion is provided a mirror-finished mirror portion, and the head portion is provided a mirror-finished mirror portion on the entire area of the head front surface exposed to the combustion chamber and the entire area of the outer peripheral surface exposed to the combustion chamber.

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.

A system and related apparatus and method for delivering fluid to and from a bottom center of a floor-operation pad on a rotary-motion flooring machine while the pad is rotationally operating on a horizontal underfoot surface, the system comprising a fluid-delivery hub comprising: a plurality of fluid entry openings disposed on an outside circumferential surface thereof; an equal plurality of fluid flow channels commencing at the fluid entry openings, angling downward and inward from the fluid entry openings toward a center of the fluid-delivery hub, and terminating at an equal plurality of fluid exit openings proximate a bottom center of the fluid-delivery hub; and a floor-operation interface at a bottom of the fluid-delivery hub configured to directly or indirectly attach a floor-operation pad thereto, for operating on a floor.

To provide an installation for cleaning and/or deburring workpieces, comprising a treatment region configured to enable a cleaning treatment and/or a deburring treatment to be performed on a workpiece therein, a loading device for transferring the workpiece from an outer area of the installation into the treatment region and an unloading device for transferring the workpiece from the treatment region into the outer area of the installation, with which installation there is achieved a high workpiece throughput with a favourable cleaning and/or deburring result, it is proposed that the loading device and/or the unloading device comprises at least one treatment device configured to enable the workpiece to be treated during the transfer between the outer area of the installation and the treatment region of the installation.
