Abstract: Disclosed is a coaxiality detecting tool composed of a hexagon flange nut, a measuring column and a detection sleeve. When the coaxiality detecting tool is used, a cone of the measuring column is matched with a cone hole of a detected workpiece, the hexagon flange nut is matched with a threaded column of the measuring column, and the measuring column is fixed on the workpiece; an inner hole of the detection sleeve is matched with a detection column, the conical surface of the detection sleeve is in contact with the orifice of a ?E hole in the workpiece, whether the whole conical surface is in uniform contact with the orifice of the ?E hole is observed, and if in uniform contact, the detected coaxiality is qualified, otherwise, the detected coaxiality is unqualified.

Abstract: The application discloses a multi-station wheel burr removing device, includes lifting translation systems, a clamping drive system and grinding systems. In practical use, the four V-shaped rollers clamp a wheel, a sixth servo motor and the first electric servo cylinder respectively adjusts the angle and the position of the rolling brush, and when the rolling brush contacts the edge of a wheel flange, burrs can be removed; the fifth servo motor and the sixth servo motor respectively adjusts the position and the angle of the lower grinding head, and when the lower grinding head contacts a wheel valve hole, burrs below can be removed; the third servo motor and the second electric servo cylinder respectively adjusts the angle and the position of the upper grinding head, when the upper grinding head contacts the wheel valve hole, burrs can be removed.

Abstract: The application discloses a multi-station wheel burr removing device, includes lifting translation systems, a clamping drive system and grinding systems. When the device is used, a cylinder II drives a left sliding plate to move right so that four V-shaped rollers clamp a wheel, and a servo motor I drives the clamped wheel to rotate; a servo motor VI adjusts the angle of a rolling brush, an electric servo cylinder I adjusts the position of the rolling brush; cylinders I drive the rolling brush to ascend; a servo motor III adjusts the angle of the upper grinding head, an electric servo cylinder II adjusts the position of the upper grinding head, and cylinders III drive the upper grinding head to descend.
