Abstract:
A work holding apparatus, which can be set up at low cost, for an assembly configured by stacking a plurality of components. A holding apparatus includes plurality of cylindrical collets arranged in a row; a plurality of cylindrical pieces arranged between the collets; and a pressurizing apparatus, which is inserted into the collets and the pieces and applies pressure to sandwich the collets and the pieces from the both end sides. The outer diameter of the piece is larger than the inner diameter of the collet at the center, becomes smaller toward the both ends from the center, and is smaller than the inner diameter of the collet at the both ends.
Abstract:
A supply line for supplying a sealant from a sealant supply source to a sealing robot has pressure sensors and is coupled to relief valves through branch lines. If the pressure in the supply line excessively rises or drops, then the relief valves are opened to release the pressure from the supply line and the supply pump is inactivated. The pipes, devices, and pump on the supply line are therefore protected from damage. The sealing robot has an sealant applicator gun movable with respect to an article to which the sealant is to be applied by the sealing robot. A pump driving device is controlled to vary the rate at which the sealant is discharged from the pump as a function of the speed of relative movement of the sealant applicator gun with respect to the article.
