Abstract

The invention discloses a quick positioning measuring device for a three-coordinate fixture. The quick positioning measuring device comprises a measuring platform, a multi-threaded-hole protective bottom plate, the part fixture, a measuring machine, positioning pin pressing columns, a quick elastic clamp and a measuring fixture quickly-adjustable device. The positioning pin pressing columns and the quick elastic clamp lock and position the part fixture through a three-point layout. The measuring fixture quickly-adjustable device is of a long-strip-shaped structure arranged on the side face ofthe bottom plate of the part fixture, one end of the measuring fixture quickly-adjustable device is fixedly connected with the bottom plate of the part fixture, and the other end of the measuring fixture quickly-adjustable device is provided with a relative position fine adjusting part of the bottom plate of the part fixture; and the side face of the middle, back onto the bottom plate, between thetwo ends is attached to one of the three-point-type positioning pin pressing columns in an abutting mode, and thus fine adjusting of the relative position fine adjusting part obtains support reverseforce from the positioning pin pressing column to push the bottom plate to move so as to adjust the parallel states of a to-be-measured part and the part fixture relative to the measuring machine. Through structural simplification and optimization, the rough adjusting and fine adjusting precision is high.
