Abstract

A broken-line trajectory generating mechanism, which has a base, and its special features are: two reference shafts are arranged on the base, and a driving differential gear train and a driven differential gear train are respectively arranged on the reference shafts. Transmission wheels are arranged outside the small sun gears in the two differential gear trains, and the drive wheels are connected by intermediate wheels or chains. The small sun gear of the active differential gear train and the driven differential gear train The large sun gear is connected through a connecting rod or a gear transmission mechanism I, and the planetary carrier of the driven differential gear train is composed of an external gear set on the reference shaft and a short shaft fixed on the external gear. The external gear and the driving differential The large sun gear of the driving gear train is connected through the gear transmission mechanism II, and an indicator rod is arranged on the driving differential gear train. The advantages are compact structure, reliable movement, and the ability to realize the movement of complex trajectories such as broken lines. It has a wide range of applications and can be widely used in equipment that requires complex movement trajectories, such as mechanical automatic processing and robot arm mechanisms, and is easy to operate.

Description

technical field [0001] The invention relates to a mechanical movement mechanism, in particular to a broken-line trajectory generation mechanism. Background technique [0002] Common motion mechanisms in the machinery industry include cam mechanisms, gear mechanisms, linkage mechanisms, wheel trains, and ratchet mechanisms, sheave mechanisms, incomplete gear mechanisms and cam intermittent motion mechanisms, which can achieve reciprocating linear motion, reciprocating swing and Various forms of mechanical motion such as rotation, but none of these motion mechanisms can realize the motion of the broken line track. Contents of the invention [0003] The object of the present invention is to provide a broken-line trajectory generating mechanism with compact structure, reliable action, high transmission efficiency and wide application range, which can realize the movement of the broken-line track. [0004] The present invention is realized in this way: it has a base, and its s...
