Abstract

According to the assembling demands of precise small parts with interference fitting

a precision pressing-fitting instrument for assembling small parts was developed. Through analyzing the relation of pressing-fitting force and the instrument's elastic deformation in pressing-fitting process

the parts' pressing-fitting displacement was compensated to increase assembly accuracy. A kind of machine vision device with upper and lower vision fields was used to detect relative situation of parts

and a

displacement platform was used to align the positions of the parts. A calibration method of the machine vision device was proposed. The relation between pressing-fitting force and pressing-fitting displacement was analyzed

and the predicted values of force and displacement were proposed to judge the assembly rationality. Five kinds of parts obtained randomly was assembled. The experimental results show that pressing displacement-pressing force curve is consistent with the predicted values. The parts' relative position deviation is less than ±5 μm

and vertical deviation is less than 10 μm

which meets the requirements of the assembly accuracy index.
