Abstract
A rapier loom electromagnetic type actuator relates to the technical field of rapier loom actuators, and comprises a stator (1) and an active cell (2). The active cell (2) is arranged in the stator (1), and the stator (1) is composed of a stator core (3) and a three-phrase winding. Six grooves (1-1) are uniformly arranged on the inner side of the stator core (3), and the inside of each groove (1-1) is provided a coil. The six coils are two A-phrase coils, two B-phrase coils, and two C-phrase cools. The rapier loom electromagnetic type actuator is high in control accuracy, simple in structure, free from maintenance, and convenient and simple to use.
Description
Technical field:
The present invention relates to Rapier looms Drive technology field, be specifically related to a kind of rapier loom main shaft electromagnetic type axially-movable servo drive.
Background technology:
Rapier looms belongs to a kind of of shuttleless loom, is one of leading type of giving priority to of China's textile machinery industry.Novel gripper loom is subjected to liking of users deeply with its high speed, fabric width, high-quality, the characteristics such as varietal adaptation is strong and noise is low.It is advantageous that: 1, varietal adaptation is strong.Rapier looms is good to the many varietal adaptations of production small lot.Cotton, hair, silk, fiber crops can both be knitted on the Rapier looms, and fit and knit BLENDED FABRIC, and particularly the self-figure yarn-dyed fabric has unique advantage.2, speed is fast, and efficient is high.It is high that Rapier looms enters the latitude rate, and rotating speed is fast, and yield per unit area is high.
Referring to Fig. 1, existing Rapier looms utilizes hydraulic valve that main shaft is axially pushed to two different stations when main shaft stops the rotation, and realizes two kinds of different interlock modes of loom gear.
There are the following problems in Rapier looms manufacturing and actual motion for this hydraulic axial motion type of drive:
One, the appearance of axially-movable hydraulic mechanism is so that the Rapier looms complex structure;
Two, there is Leakage in the axially-movable hydraulic mechanism, needs to safeguard.
Summary of the invention:
The purpose of this invention is to provide a kind of Rapier looms electromagnetic actuator, its control accuracy is high, and is simple in structure, need not keep in repair, simple and easy to use.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it comprises stator 1, mover 2, mover 2 is arranged in the stator 1, described stator 1 is comprised of stator core 3 and three phase windings, the inboard of iron core 3 evenly is provided with six groove 1-1, be provided with coil in six groove 1-1, six coils are two A phase coils, two B phase coils, two C phase coils.
Described mover 2 is one section steel axle on the loom main shaft.
Described unshakable in one's determination 3 adopt silicon steel sheet radially to rotate is overrided to form, and forms a cylindrical shape
The present invention is when loom main shaft during in any one axial station rotary operation, and all stator winding no powers of electromagnetic type axially-movable driver do not produce magnetic field, and motion of main shaft is not exerted an influence.When main shaft needs axially-movable, pass into symmetrical three-phase current by frequency converter to three-phase stator winding.When the electric current phase sequence is A, B, C successively leading 120 ° the time, will produce a travelling-magnetic-field that moves right, cutting mover steel axle produces induced potential and electric current at mover, and then produces electromagnetic force to the right, promotes mover (main shaft) axially-movable to the right.When the electric current phase sequence is that A, B, C lag behind 120 ° the time successively, will produce the travelling-magnetic-field to left movement, cutting mover steel axle produces induced potential and electric current at mover, and then produces electromagnetic force left, promotes mover (main shaft) axially-movable left.After the main shaft axially-movable puts in place, the outage of three phase windings, travelling-magnetic-field and electromagnetic push disappear.
The present invention has the following advantages:
One, the structure of loom axial motion mechanism can be simplified;
Two, electromagnetic type mechanism controls precision is high;
Three, the electromagnetic type axial motion mechanism is non-maintaining;
Four, because of this mechanism without permanent magnet, under two normal stations of main shaft, without magnetic field, thereby can not produce because rotatablely moving loss in the mechanism, to the loom operation without any adverse effect.

Fig. 1 is the structural representation of background technology,
Fig. 2 is structural representation of the present invention,
Fig. 3 is the view in transverse section of Fig. 2.
The specific embodiment:
Referring to Fig. 2-Fig. 3, this specific embodiment adopts following technical scheme: it comprises stator 1, mover 2, mover 2 is arranged in the stator 1, described stator 1 is comprised of stator core 3 and three phase windings, the inboard of iron core 3 evenly is provided with six groove 1-1, be provided with coil in six groove 1-1, six coils are two A phase coils, two B phase coils, two C phase coils.
Described mover 2 is one section steel axle on the loom main shaft.
This specific embodiment is when loom main shaft during in any one axial station rotary operation, and all stator winding no powers of electromagnetic type axially-movable driver do not produce magnetic field, and motion of main shaft is not exerted an influence.When main shaft needs axially-movable, pass into symmetrical three-phase current by frequency converter to three-phase stator winding.When the electric current phase sequence is A, B, C successively leading 120 ° the time, will produce a travelling-magnetic-field that moves right, cutting mover steel axle produces induced potential and electric current at mover, and then produces electromagnetic force to the right, promotes mover (main shaft) axially-movable to the right.When the electric current phase sequence is that A, B, C lag behind 120 ° the time successively, will produce the travelling-magnetic-field to left movement, cutting mover steel axle produces induced potential and electric current at mover, and then produces electromagnetic force left, promotes mover (main shaft) axially-movable left.After the main shaft axially-movable puts in place, the outage of three phase windings, travelling-magnetic-field and electromagnetic push disappear.
This specific embodiment has the following advantages:
One, the structure of loom axial motion mechanism can be simplified;
Two, electromagnetic type mechanism controls precision is high;
Three, the electromagnetic type axial motion mechanism is non-maintaining;
Four, because of this mechanism without permanent magnet, under two normal stations of main shaft, without magnetic field, thereby can not produce because rotatablely moving loss in the mechanism, to the loom operation without any adverse effect.
