Straight reciprocating motion mechanism

Abstract

The invention discloses a straight reciprocating motion mechanism and belongs to the field of mechanical structures. The straight reciprocating motion mechanism disclosed by the invention comprises a support, a reciprocating mechanism and a driving mechanism; the reciprocating mechanism comprises a first screw, a second screw, a first rocker, a sliding component, sliding rails, a second rocker, a spring, a left guide block, a right guide block and a guide block mounting bracket; the rear side part of the first rocker is provided with a first half nut and a second half nut; when the first rocker rotates by taking a supporting axle at the middle part of the first rocker as the center, the first screw can be matched with the first half nut or the second screw can be matched with the second half nut; the rear end of the second rocker is movably arranged at the front side part of the first rocker; the second rocker is provided with a protrusion and a spring connecting part; the protrusion is movably embedded into an arc-shaped groove in the first rocker; two ends of the spring are respectively connected with the spring connecting part and the supporting axle; the left guide block and the right guide block are respectively arranged at two ends of the sliding stroke of the sliding component; the first screw and the second screw are driven to reversely rotate by the driving mechanism, and therefore the problem of lower stability of the existing linear reciprocating motion mechanism is solved.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and in particular relates to a linear reciprocating motion mechanism. Background technique [0002] In mechanical equipment, linear reciprocating motion mechanisms are often used. Common linear reciprocating motion mechanisms include: crank slider mechanism, eccentric wheel mechanism, sheave mechanism, and cam mechanism. Currently, these linear reciprocating motion mechanisms are usually One end drives the other end to move, and the reciprocating motion generated is single, and only one end can perform linear reciprocating motion. In many cases, it is not flexible enough to use, especially the linear distance during reciprocating motion is difficult to accurately adjust and control, with poor stability and low precision. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing linear reciprocating motion mechanism, which are n...
