Problems solved by technology

However, the length of the crank rod in the traditional crank-link mechanism cannot be adjusted, or can only be adjusted manually. This not only greatly affects the transmission requirements of the mechanism, but also makes it impossible for the mechanism to obtain an accurate output trajectory. Manual length adjustment also increases the workload of the staff. workload, reducing work efficiency

Abstract

The invention discloses a crank connecting rod mechanism capable of automatic adjustment of length. The crank connecting rod mechanism capable of automatic adjustment of length comprises a crank rod structure and a connecting rod assembly. The crank rod structure comprises a supporting unit and a movement unit arranged on the supporting unit. The movement unit comprises an annular gear, a planet carrier and a planet gear, wherein the annular gear is rotatably installed on the supporting unit and provided with internal teeth, the planet carrier is rotatably installed on the supporting unit, andthe planet gear is rotatably installed on the planet carrier and provided with external teeth. Moreover, the rotary shaft of the annular gear and the rotary shaft of the planet carrier are collinear.The planet gear and the internal teeth of the annular gear mesh with each other. By means of the crank connecting rod mechanism capable of automatic adjustment of length, the length of the crank rodstructure in the crank connecting rod mechanism can be adjusted automatically, and thus the purpose that more accurate trajectory can be output by the crank connecting rod mechanism is achieved.

Description

technical field [0001] The invention relates to a transmission device, in particular to a crank connecting rod mechanism whose length can be automatically adjusted. Background technique [0002] At present, robot manufacturing has become a research hotspot, and most of the robots developed need to use crank-link mechanism for transmission. However, the length of the crank rod in the traditional crank-link mechanism cannot be adjusted, or can only be adjusted manually. This not only greatly affects the transmission requirements of the mechanism, but also makes it impossible for the mechanism to obtain an accurate output trajectory. Manual length adjustment also increases the workload of the staff. workload, reducing work efficiency. [0003] Therefore, it is particularly important to develop a crank-link mechanism that can automatically adjust the length. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a crank c...
