A locating device for positioning a workpiece on a processing apparatus are disclosed. A first embodiment includes a base (22) and a fixture plate (24) with positioning means (30, 32) between the base and the fixture plate. An abutment (80) defines a fixed reference point for locking the fixture plate on the base through a clamping mechanism (100). The clamping mechanism also includes release cylinders (120) so that the fixture plate can be quickly interchanged for introducing a new workpiece. A second embodiment includes a base structure that comprises a first clamping unit (301a) and a second clamping unit (301b) that support a fixture plate (224) therebetween. First positioning means (330) secured to each clamping unit (301a, 301b) cooperate with second positioning means (232) secured to the fixture plate (224). Clamping means (530) engage and lock the fixture plate (224) in position. The clamping means (530) include locking members (531) that are slidably disposed in channels (303) in the blocks (302).
