DETAILED DESCRIPTION
The vision system of the present invention is used for locating a part or fixtured parts on a CMM (coordinate measuring machine) or a CNC (computer numeric control) Vision system. These machines are used for automatic dimensional measurement.
The Vision Slide ensures that the part which has been placed on the automatic dimensional measurement machine will not move by the use of the concentrated magnetic-field magnets that holds the part securely against both magnetic working faces, locating the part precisely on the machines staging surface. This established position establishes a starting point which can be reproduced or repeated. This starting point can be located anywhere on the table, depending on the optimal position desired for accommodating the part or parts to be measured. There is an adjustable slide scale in both the X and Y axis. By changing the position of the slide scales in either axis by the use of the side engagement pins the operator or programmer can choose several positions in either axis, such as, A through G in the Y-axis and 1 through 9 in the X-axis.
When a programmer writes a program, he will indicate in the instructions where to set these scales before loading the part to be inspected. The operator puts the slide scales in the proper position and then loads the part on the staging table against the magnetic/air suction or forceless material providing 1, 2 or 3 points of contact for the positioning of a fixture or part in its coincident plane and providing a stop location in its draw force or coincident locating plane and providing either the primary, secondary or tertiary planer stop.
All the operator has to do at this point is to start the program and the machine will locate the part. Even if someone wants to do a quick manual check without the use of a program, they can just place the part or fixture into the corner against the magnetic/air suction or forceless material providing 1, 2 or 3 points of contact for the positioning of a fixture or part in its coincident plane, providing a stop location in its draw force or coincident locating plane and providing either the primary, secondary or tertiary planer stop. The part is now secure and square, being held optimally for measurement.
The Vision Slide provides the necessary functions to make dimensional automated measurements accurately and efficiently with ease.
