Method and device for aligning a workpiece on a machine tool table |
摘要 |
The workpiece or pack of printed circuit boards is fitted to a clamping fixture carried by the table and is machined by a machining head; the head and the table being movable with respect to each other along two coordinate X, Y axes. The aligning method includes the steps of providing the pack with two locating holes; fitting the pack to the fixture; determining the distances between the real positions of the holes and two reference positions; and moving the pack on the fixture to eliminate the distances. The aligning device has an optoelectronic sensor carried by the head to determine the real position of each hole; and a number of motors controlled on the basis of the real position of each hole to move a locating member for locating a first pin on the pack, and to move one bar of a pair of bars for clamping the other pin on the pack.
