AI Technical Summary
Existing press-fitting machines cannot identify whether bushings have been reduced in diameter. This results in excessive interference between bushings that have not been reduced in diameter and the finished product assembly holes when they are directly press-fitted, leading to scrap products and affecting production efficiency.
A bushing press-fit fixture with detection function was designed. By sliding the detection sleeve onto the press head, only standard-sized bushings are allowed to be installed, while bushings without reduced diameter are excluded. The press-fitting of the bushing is completed by using a driver to drive the top plate and the press head.
This technology enables the detection and elimination of bushings that have not been reduced in diameter, ensuring an interference fit between the bushing and the assembly hole of the finished product, thereby improving production efficiency and product quality.
