Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of stability is high, precision is high, consumes less, the balance arm of force eliminates vibration, simply a kind of shedding motion based on servomotor of structure, and the technical scheme realizing above-mentioned purpose is as follows:
A kind of shedding motion based on servomotor, it is characterized in that: comprise motor, deceleration device, eccentric wheel, heald frame push rod, heald frame, linkage, wherein motor is electrically connected with deceleration device, deceleration device is connected with eccentric wheel, motor is rotated by deceleration device band movable eccentric wheel, simultaneously movable on eccentric wheel connection linkage device, the end of linkage is connected with heald frame push rod, heald frame push rod is connected with heald frame, eccentric motion is converted to the rectilinear motion that up and down or left and right is waved by linkage, linkage drive heald frame push rod does the rectilinear motion that up and down or left and right is waved, heald frame top rod driving heald frame does the motion that up and down or left and right is waved simultaneously.
Preferably, described linkage comprises push rod, the first rocking arm, connecting rod, the second rocking arm, and described first rocking arm, the second rocking arm are V-structure, and being fixed in frame as fulcrum of the tie point activity of the first rocking arm, second in the middle of rocking arm; Wherein push rod one end activity be connected on eccentric wheel, the other end is flexibly connected with the first one end, the other end of the first rocking arm is flexibly connected connecting rod, the other end of connecting rod is flexibly connected the second one end, connecting rod is the level of state after being connected with the first rocking arm, the second rocking arm, the other end of the second rocking arm is flexibly connected heald frame push rod, and the second rocking arm drive heald frame push rod does the rectilinear motion that up and down or left and right is waved.
Preferably, the angle of the V-structure of the second rocking arm is 90 degree.
Preferably, described motor is servomotor.
Preferably, described deceleration device is reductor.
Based on the method for work of the shedding motion of servomotor, it is characterized in that: electric machine rotation, power exports from eccentric wheel after reductor adjustment, push rod is arranged on eccentric side, make push rod be in oscillating motion, push rod drives the first rocking arm to swing, drivening rod motion after the first rocking arm swings, link motion drives again the second rocking arm to swing, and final second rocker arm displaces heald frame push rod does the rectilinear motion that up and down or left and right is waved.
The present invention has that stability is high, precision is high, it is little to consume energy, the balance arm of force eliminates vibration, and smooth running, impulsive force are little, noise is low meets the characteristics of motion, and structure is simple, manufacture cost and other advantages.
