A work holding device is intended for use in combination with a processing machine, such as an assembling apparatus, an industrial robot or a machine tool. The work holding device comprises a base plate (8), a slide base (9) supported for vertical movement on the base plate (8), a swivel head (10) supported for turning on the slide base (9), and a rotary table (11) supported on the swivel head for rotation about an axis perpendicular to the axis of turning of the swivel head. The slide base (9), the swivel head (10) and the rotary table (11) are controlled properly to set a work (12) held on the rotary table (11) in an optional position relative to the associated processing machine. The work holding device and the processing machine are controlled for synchronous operation by a single controller according to a control program.

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a work holding device capable of setting a work in an optional position suitable for assembling or machining.
In one aspect of the present invention, a work holding device comprises a vertical base plate, a slide base supported for vertical movement on the front surface of the vertical base plate, an L-shaped swivel head supported for rotation on the slide base, and a rotary table supported for rotation on one end of the rotary block.
The work holding device, in accordance with the present invention, does not place restrictions on the processing direction of an industrial robot or the like, enables processing a work in many directions, does not place restrictions related to the processing direction on the design of the work, enables the curtailment of time for designing the work, and increases the degree of freedom of design.
