Abstract

A vacuum-operated tool for picking up a shielded ball race during robotic assembly has a central pin and external sleeve for locating the internal and external peripheries of the ball race, respectively, when it is picked up. An internal seal isolates all but the inner member of the ball race from the applied vacuum to prevent grease from being drawn from the bearing. Both pin and sleeve of the tool are compliant in the fitting direction so that the ball race may be fitted onto a shaft and into a housing in one operation. The tool shown in the figure has a hollow cylindrical body portion 1 with a circular flange 2 at one end. A central pin 3 extends into and through the axial bore of the body portion 1. Another sleeve 4 surrounds the flange and is normally held in place abutting the flange by a light spring 5.

Ball Race Picking Tool

A vacuum-operated tool for picking up a shielded ball race during robotic assembly has a central pin and external sleeve for locating the internal and external peripheries of the ball race, respectively, when it is picked up. An internal seal isolates all but the inner member of the ball race from the applied vacuum to prevent grease from being drawn from the bearing. Both pin and sleeve of the tool are compliant in the fitting direction so that the ball race may be fitted onto a shaft and into a housing in one operation. The tool shown in the figure has a hollow cylindrical body portion 1 with a circular flange 2 at one end. A central pin 3 extends into and through the axial bore of the body portion 1. Another sleeve 4 surrounds the flange and is normally held in place abutting the flange by a light spring 5. The outer sleeve 4 and central pin 3, when protruding beyond the body portion, define an annular aperture of a size and shape to receive a ball race 6 required during assembly. An axial bore 7 into the central pin 3 and out sideways into the annular aperture is connected to a vacuum source (not shown). An annular polyurethane seal 8, with a ridge 9 around its internal circumference, is attached to the lower surface of the body portion within the annular aperture. In operation, the tool is placed over a ball race to be picked up. The inner pin 3 enters first to locate the inner diameter of the ball race. As the outer sleeve becomes clo...
