Workpiece Loading Device for Nc-Machine Fixtures

This article describes a device for robotized loading of workpieces in fixtures of numerically controlled (NC) machines.

For many manufacturing operations it is necessary to manually place the workpiece in a fixture, place the retaining means onto the workpiece and tighten a number of bolts and nuts for securing the workpiece properly.

This is, of course, a time consuming and thus expensive operation. There are no commercially available means or devices for automatization of this kind of task, and the present invention has provided a simple and efficient means for achieving an automatization of the mentioned operation as an objective.

Following is a detailed description of an embodiment of the device referring to Figs. 1 and 2.

In Fig. 1 the device 1 is shown schematically, and it comprises a console C, mounted on a plate P. The plate is provided with an element G which is adapted to provide a gripping point for a robot gripper. There is also provided an air motor M, the outgoing axle (not shown) of which drives a nut-tightening means 3. This means 3 is connected to the axle via splines 4 so that it is movable in the longitudinal direction of the device.

On the fixture F (Fig. 2) of an NC machine there are pivotable clamps 5 for the workpieces. These clamps are, for the purpose of using the device, provided with pins 6 that protrude outwardly towards the tightening means.

The pins 6 are receivable in driving slots 7, in the form of cut-out circular segments in a cylindrical member 8, mounted circumfe...
