Abstract: The present invention relates to a slider driving mechanism on a CNC assembly machine for assembled camshaft. The mechanism includes a servo motor (1), the host frame (5), ball screw (6), linear guides (9) and the slider body (8), wherein, the servo motor (1), ball screw (6) and linear guides (9) are mounted vertically on the host frame (5). The servo motor (1) connects with the ball screw. The slider body (8) connects with both the ball screw (6) and the linear guides (9). It is driven by a ball screw (6) and moves along a linear guides (9) in the vertical direction. The present invention is novel. It not only can greatly improve the assembly speed of cam, hexahedron on assembled camshaft and improve productivity, but also can eliminate complex gear system. It makes the manufacturing and processing more simple. The installation is also more convenient. It can further improve product quality and manufacturing precision of assembled camshaft.
