The present invention discloses a roller-type wheel flange surface powder removing device, that includes a corresponding roller brush that is replaced according to the size of a wheel to be processed. A manipulator places the wheel at corresponding positions of limit discs, output ends of cylinders extend to drive pressure blocks to press the wheel, and a sliding seat and a mechanism thereon reciprocate along with a rack within the travel range of guide pillars. While a second motor starts working, a first motor drives a second gear to rotate, and a first gear transmits the rotation speed to the roller brush through a support shaft according to a certain transmission ratio. The roller brush is driven by a third gear 23 and a rack 24 while rotating with the support shaft. The roller brush reciprocates to clean the surface of the wheel.

A device for removing circumferential burrs of a wheel with high precision includes an electric cylinder, a lifting table, guide rails, an electric cylinder, a sliding block, a plurality of sensors, a rim burr cutter, a riser burr cutter, and the like. The device can simultaneously remove circumferential burrs from the flange edge, the outer rim and the riser slot edge, which eliminates the error caused by coaxial degree deviation, so that the rotating center of the cutters coincides with the circumferential center of the burrs. The device is configured to provide high-precision removal of burrs from the flange edge, and high-precision removal of burrs from the outer rim and the riser.

The present invention generally relates to assembly equipment of valve body, especially to riveting and grinding assembly for nozzle of screw shaft valve. The invention may include a rack, a power control box, a turntable and a turntable divider. A carrier assembly which engages with the screw shaft valve body is installed on the edge of the turntable with uniform distribution. On the center part of the turntable, a support shaft which is installed on and fixed with the rack is vertically interposed and on the top of the support shaft, an upper supporting disc is installed. A valve pipe feeding device, a valve pipe preloading device, a valve pipe riveting device and a valve pipe grinding device which engage with the carrier assembly are installed on the said rack on the rotational direction of turntable. As the threaded pipe is put into the carrier assembly by valve pipe feeding device, the carrier assembly rotates counterclockwise along the turntable and rotates to the valve pipe feeding device to the press threaded pipe into the valve seat. Thereafter the carrier assembly rotates the valve pipe riveting device and rivets threaded pipe with a valve flange in order to finish assembling process. Finally, the carrier assembly rotates the valve pipe grinding device to grind nozzle of valve to finish grinding and riveting process of threaded pipe with high positioning accuracy of assembly and marvelous hermetic sealing.

A rectangular glass substrate has a front surface, a back surface, four side surfaces, and eight chamfered surfaces, and a thickness of at least 6 mm. A first curved surface along the edge line between the front surface and the chamfered surface disposed adjacent thereto has an average gradient of up to 25% in a range from the front surface to a position of 50 m below the front surface when the substrate is rested horizontal with the front surface facing upward. A second curved surface along the edge line between at least one of four side surfaces and the chamfered surface disposed adjacent to the front surface has an average gradient of at least 30% in a range from the at least one side surface to a position of 50 m below the at least one side surface when the substrate is rested horizontal with the at least one side surface facing upward.

A machine for cleaning/deburring sides of rectangular parts includes four brushes. The four brushes include a first pair of brushes adapted to clean two opposite sides of the rectangular parts and a second pair of brushes adapted to clean remaining two opposite sides of the rectangular parts. The machine also includes a mounting frame for mounting the four brushes. The four brushes are mounted on the mounting frame such that axes of rotation of the first pair of brushes and one of the brushes out of the second pair of brushes lie in a common plane, and the remaining brush of the second pair of brushes is placed offset from said common plane so that the first pair of brushes engage with complete side face without interfering with the second pair of brushes.
