Abstract
The invention discloses a non-circular gear-crank rocker-gear train weft insertion and conjugate cam beating-up mechanism. Two ends of a spindle of a rapier loom are respectively provided with a set of weft insertion and beating-up mechanism. In each set of mechanism, the spindle of the loom is fixed with a weft insertion active non-circular gear and a beating-up conjugate cam. A conjugate non-circular gear pair transmits power to a weft insertion rapier gripper through a crank rocker, two pairs of cylindrical gears, a pair of bevel gears and a rapier wheel to form the weft insertion mechanism so as to complete weft conveying and weft connecting actions. The conjugate cam directly transmits power to a beating-up steel reed to form a beating-up mechanism to complete the beating-up action and ensure that a going part has a complete pause time of about 240 degrees in a back center. By making initial engagement position angles of non-circular gears in the weft insertion mechanism on the two sides different, relay weft insertion is realized, an acceleration rule of the rapier gripper is an isosceles trapezoid by optimizing a non-circular gear pitch curve, and the weft yarn tension is reduced.
Description
Technical field
The present invention relates to a kind of Weft insertion mechanism of rapier loom and beating-up mechanism, be specifically related to a kind of non-circular gear-crank rocker-train wefting insertion, beat-up Conjugate Cam.
Background technology
The effect of weft insertion device is that the non-at the uniform velocity regular linear reciprocation that the uniform speed rotation with rapier loom main shaft is converted into the sword head moves.At present, the Weft insertion mechanism of rapier loom of selling on the market at home mainly contains: the conjugate cam weft insertion device, and the type mechanism is easy to satisfy the characteristics of motion of wefting insertion requirement, but the cam profile requirement on machining accuracy is quite high, as exist error just to produce impact; Variable-pitch auger transmission weft insertion device, the secondary processing difficulties of the variable-pitch auger of the type mechanism; Plane six connecting rods send latitude, four link latitude mechanisms, can conveniently realize " relay " wefting insertion, but its motion of weft-insertion rule design flexibility is not as the conjugate cam weft insertion device; The space four-links weft insertion device, its motion of weft-insertion rule design flexibility send latitude, four link latitude mechanisms not as plane six connecting rods.
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, requires slay that dead time or " the approximate pause " time will be arranged in heart position, back, so that there is adequate time to accomplish the wefting insertion action.At present; The loom beating-up mechanism that sells on the market at home mainly contains: four connecting rod beating-up mechanisms, if allow the displacement of beating up about 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 superior to 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 higher than four connecting rod beating-up mechanisms.
Summary of the invention
The purpose of this invention is to provide a kind of non-circular gear-crank rocker-train wefting insertion, beat-up Conjugate Cam; This two mechanism can satisfy the woven wefting insertion of Rapier looms and beat up technological requirement, realizes having the non-at the uniform velocity straight reciprocating motion rule of sword head and the requirement of " relay " wefting insertion of " isosceles trapezoid " acceleration; Satisfying slay simultaneously has the complete dead time about 240 ° in heart position, back, and process and assemble is convenient, guarantees precision easily.
