Abstract:
1. A shaft straightening apparatus comprising: a frame, the frame having an open area dimensioned to receive a shaft in the open area; two holding devices on the frame adjacent the open area, each holding device having a rod that is extendible from the holding device and retractable to the holding device, the rod being extendible from the holding device into the open area to engage against a shaft that has been positioned in the open area and support the shaft where engaged by the rod; a proximity sensor on the frame adjacent the open area, the proximity sensor being operable to sense a distance from the proximity sensor to a shaft that has been positioned in the open area and is supported by the holding device rods of the two holding devices, and to output a signal that is indicative of the sensed distance; an actuator device on the frame at an opposite side of the open area from the two holding devices, the actuator device having a ram that is extendible from the actuator device and retractable to the actuator device, the ram being extendible from the actuator device into the open area to engage against a shaft that has been positioned in the open area and is supported by the holding device rods of the two holding devices, and to bend the shaft while moving the shaft a distance through the open area while the proximity sensor senses the distance the shaft is moved through the open area by the ram.
