Abstract
The invention discloses an elliptic-gear and oscillating-leader beating-up method and a beating-up mechanism. An elliptic-gear mechanism and an oscillating-leader mechanism are adopted to realize the law of motion required by a batten via changing the uniform rotation of a loom spindle into the periodic fitful reciprocating swing of a swing shaft. A crank in the oscillating-leader is fixedly connected on a driven non-circular gear and is rotated therewith, the other end of the crank is in higher pair connection with an arc chute on the oscillating-leader, thereby realizing the complete pause of about 240 DEG for the batten at the back center position, fully satisfying the beating-up process requirement of the loom, and finishing the beating-up action.
Description
Technical field
The present invention relates to loom beating-up mechanism, be specifically related to a kind of elliptic gear-swinging conductive pole beating-up method and beating-up mechanism.
Background technology
The effect of beating-up mechanism is the non-at the uniform velocity swing that the uniform speed rotation of loom main shaft is converted into rocker, in order to guarantee that loom has the sufficient time to finish the wefting insertion action, require slay that long complete dead time or " the approximate pause " time will be arranged in heart position, back.At present, the loom beating-up mechanism that sells on the market at home mainly contains: beat-up Conjugate Cam, the type mechanism is easy to satisfy the characteristics of motion of beating up and requiring, can realize the complete dead time about 240 °, but the cam profile requirement on machining accuracy is quite high, as exists error just to produce impact; Four connecting rod beating-up mechanisms, if the displacement of beating up about permission 5mm can realize " the approximate pause " time about 65 °, performance is mainly used in the Nonseparation slay than beat-up Conjugate Cam difference; Six connecting rod beating-up mechanisms, if allow the displacement of beating up about 5mm, can realize " the approximate pause " time about 120 °, its performance is better than four connecting rod beating-up mechanisms, but than beat-up Conjugate Cam difference, this mechanism's hinge point is more in addition, and cumulative errors are big, so requirement on machining accuracy is bigger than four connecting rod beating-up mechanisms.
Summary of the invention
The purpose of this invention is to provide a kind of elliptic gear-swinging conductive pole beating-up method and beating-up mechanism, this mechanism can realize that slay has the complete dead time about 240 ° in heart position, back, satisfy the technological requirement of beating up of loom fully.
In order to achieve the above object, the technical solution used in the present invention is:
One. elliptic gear-swinging conductive pole beating-up method:
Adopt elliptic gear mechanism and oscillating guidebar mechanism, the uniform rotation of loom main shaft is transformed into the cyclical intermission reciprocally swinging of rocker.
Two. elliptic gear-swinging conductive pole beating-up mechanism:
Initiatively elliptic gear is housed on loom main shaft, initiatively elliptic gear and driven elliptic gear are meshed, initiatively the pivot of elliptic gear is the focus O of active elliptic gear, the pivot of driven elliptic gear is the focus A of driven elliptic gear, one end of crank and driven elliptic gear concrete mutually, the other end B point of crank is connected with groove higher pair on the fork through roller, and an end of fork can be made periodic intermittently reciprocally swinging around the C point.
Described crank and driven elliptic gear concrete mutually, and with the angle of major axis be 0 °, initiatively the initial installation site of elliptic gear and driven elliptic gear is that major axis is horizontal, this moment, fork was in farthest right position.
One groove is arranged on the described fork, this groove by 1 section arc groove and 2 sections with it the tangent straight trough in two ends form, the length of straight trough l is at 10～20mm, arc groove right central angle alpha be 90 °～120 °, and the center of circle that the back arc groove is installed is on the center of rotation A of driven elliptic gear.
The eccentricity of described active and driven two elliptic gears is 0.7～0.9.
The beneficial effect that the present invention has is:
Adopt elliptic gear mechanism and oscillating guidebar mechanism, the uniform rotation of loom main shaft is transformed into the cyclical intermission reciprocally swinging of rocker, realize the characteristics of motion that slay requires.The present invention can realize that slay has the complete dead time about 240 ° in heart position, back, satisfies the technological requirement of beating up of loom fully, finishes beating-up.
Description of drawings
Accompanying drawing is a mechanism principle schematic diagram of the present invention.
Among the figure: 1, elliptic gear initiatively, 2, driven elliptic gear, 3, crank, 4, roller, 5, fork.
The specific embodiment
Be described further of the present invention below in conjunction with drawings and Examples.
As shown in drawings, initiatively elliptic gear 1 is equipped with in the present invention on loom main shaft, initiatively elliptic gear 1 and driven elliptic gear 2 are meshed, initiatively the pivot of elliptic gear 1 is the focus O of active elliptic gear 1, the pivot of driven elliptic gear 2 is the focus A of driven elliptic gear 2, one end of crank 3 and driven elliptic gear 2 concrete mutuallies, the other end B point of crank 3 is connected with groove higher pair on the fork 5 through roller 4, and an end of fork 5 can be made periodic intermittently reciprocally swinging around the C point.
Described crank 3 and driven elliptic gear 2 concrete mutuallies, and with the angle of major axis be 0 °, initiatively the initial installation site of elliptic gear 1 and driven elliptic gear 2 is that major axis is horizontal, this moment, fork 5 was in farthest right position.
On the described fork 5 groove is arranged, this groove by 1 section arc groove and 2 sections with it the tangent straight trough in two ends form, the length of straight trough l is at 10～20mm, arc groove right central angle alpha be 90 °～120 °, and the center of circle that the back arc groove is installed is on the center of rotation A of driven elliptic gear 2.The eccentricity of described active and driven two elliptic gears is 0.7～0.9.
Operation principle of the present invention is as follows:
As shown in drawings, when the present invention worked, power passed to initiatively elliptic gear 1 by loom main shaft O input, and by being meshed of active elliptic gear 1 and driven elliptic gear 2, driven elliptic gear 2 is just done periodic non-uniform rotation around its focus A.Because crank 3 and driven elliptic gear 2 concrete mutuallies, thus crank 3 also around some A do periodic non-uniform rotation.Crank 3 other end B are connected with groove higher pair on the fork 5 by roller 4, this groove by 1 section arc groove and 2 sections with it the tangent straight trough in two ends form, and installation afterwards the center of circle of arc groove on the center of rotation A of driven elliptic gear 2.Therefore fork 5 is made periodic intermittently reciprocally swinging around the C point, also makes periodic intermittently reciprocally swinging with the slay of fork 5 concrete mutuallies, and being implemented in heart position, back has the long complete dead time, satisfies the technological requirement of beating up.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
