Abstract
A radial truing device is disclosed having two sets of parallel jaws that are spaced apart to engage the opposite bead seats of a wheel, and the like. The jaws comprise radially extending slides, and each set of jaws is actuated by a separate ring, which rotates to move overcenter devices to an inline position to move the jaws radially inwardly. The overcenter devices bear against one half of a ring, and an antifriction bearing capable of absorbing radial and lateral movement is positioned between the other half of the ring and the frame. In the preferred embodiment, the overcenter devices are toggles that are connected to the jaws and to the rings by pins, and the bearings are generally in line with the connection of the overcenter device and the ring, so that the overcenter devices run true. The rings are actuated separately so that a lateral working of the wheel can be provided and so that a sequential deformation of the wheel is accomplished by forces exerted over a greater period of time than is possible by the prior art. In addition, a radially shiftable table having a resilient surface is provided which will accommodate the complex movement of the workpiece that is produced by the two sets of jaws.
