Problems solved by technology
[0002] In engineering applications, some active rods and driven rods that cannot be directly connected need to rely on the linkage mechanism of the pull rod to realize the transmission of motion, and the combination of gears and guide rods is often used. In the existing design, long-term linkage will lead to auxiliary parts. The wear and the error of the driven movement gradually increase, bringing certain adverse effects

The invention discloses a pull rod linkage mechanism, which comprises a driving rod and a driven rod, the driving rod is connected with a first gear through a connecting rod, the first gear is hinged on a frame, and the first The gears are meshed, a first rocker is arranged between one side of the driven lever and one side of the first gear, and a second rocker is arranged between the other side of the driven lever and the other side of the first gear. The first rocker and the second rocker are arranged parallel to each other and slide grooves are arranged in parallel on the first rocker and the second rocker, and rocker arms are respectively arranged on both sides of the second gear, and each rocker The ends of the arms are respectively provided with rollers that can slide along the sliding grooves. Improve the existing tie rod linkage mechanism to avoid the phenomenon that the long-term linkage will cause the wear of the auxiliary parts and the error of the driven movement will gradually increase, and improve the service life of the equipment and the precision of the linkage.
Description
technical field [0001] The invention relates to a pull rod linkage mechanism. Background technique [0002] In engineering applications, some active rods and driven rods that cannot be directly connected need to rely on the linkage mechanism of the pull rod to realize the transmission of motion, and the combination of gears and guide rods is often used. In the existing design, long-term linkage will lead to auxiliary parts. The wear and error of the driven movement gradually increase, which brings certain adverse effects. Contents of the invention [0003] In view of the above problems, the present invention provides a tie rod linkage mechanism, which improves the existing tie rod linkage mechanism, avoids the phenomenon that the long-term linkage will cause the wear of the auxiliary parts and the error of the driven movement gradually increases, and improves the use of the equipment. Life and precision of linkage. [0004] In order to achieve the above-mentioned technic...
