Gap type reciprocating swing rod mechanism

Abstract

The invention discloses a gap type reciprocating swing rod mechanism which comprises a first crank and rocker mechanism and a second crank and rocker mechanism. The first crank and rocker mechanism is hinged to a sector-shaped swing block. A sliding guide groove is formed along an arc section of the periphery of the sector-shaped swing block. A first baffle and a second baffle are arranged at the head end and the tail end of the sliding guide groove correspondingly. The sliding guide groove is sleeved with sliding teeth. A driven gear is engaged with the sliding teeth and is mounted on a driven crank shaft of the second crank and rocker mechanism. A U-shaped groove in the radial direction is formed in the sector-shaped swing block. A connecting rod shaft of the first crank and rocker mechanism is mounted in the U-shaped groove and is hinged and fixed through a bolt. According to the gap type reciprocating swing rod mechanism, the sliding teeth on the sector-shaped swing block are pushed by the first crank and rocker mechanism to do reciprocating swing, the driven gear engaged with the sector-shaped swing block is connected with the second crank and rocker mechanism, and a swing rod of the second crank and rocker mechanism achieves up-and-down reciprocating swing. The gap type reciprocating swing rod mechanism is simple in structure, convenient to mount and good in adjusting performance.

Description

technical field [0001] The invention relates to a reciprocating swing link mechanism, in particular to a gap type reciprocating swing link mechanism. Background technique [0002] There are many types of reciprocating swing link mechanisms, which are mainly driven by eccentric slider mechanisms, multi-link mechanisms, crank rocker mechanisms, and swing guide rod mechanisms. The motion mechanisms work reliably and are suitable for different motion needs. However, there is a problem that it is difficult to realize intermittent partition driving during single-circle cycle motion. Most of them use single-circle full-area reciprocating swing motion, which cannot meet the swing needs of special applications. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an intermittent reciprocating swing mechanism with simple structure, convenient installation and good adjustment perfor...

AI Technical Summary

Problems solved by technology

Each motion mechanism works reliably and is suitable for different motion requirements, but there is a problem that it is difficult to realize intermittent partition driving in the process of single-circle cycle motion. Most of them adopt single-circle full-area reciprocating swing motion, which cannot meet the swing requirements of special applications.
