Abstract

The invention belongs to the airplane fixture detection technology and relates to an adjustable cursor seat. The cursor seat is composed of a ball seat, two slide blocks, an adjusting pin, a push rod, two pin shafts and two connecting plates. The adjustable cursor seat is capable of adjusting the outer diameter of a locating tail rod of the cursor seat for inspection according to the actual manufacturing size of an airplane fixture locating hole to locate and measure precisely, and the disadvantage of low fixture manufacturing precision due to different fixture locating apertures and manufactured aperture deviation is avoided. The adjustable cursor seat is high in working efficiency and mounting precision. The test proves that the fixture manufacturing precision arrives at 0.02 millimeters after using the adjustable cursor seat, and the fixture manufacturing precision is improved by more than 5 times.
