Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Fig. 1 to Fig. 3, a kind of Rapier looms spatial ellipsoid weft insertion device described in the utility model, comprises the spatial ellipsoid mechanism be arranged in casing 1-2, double rocker mechanism and gear enlarger.Described spatial ellipsoid mechanism is connected with the drive crank 7 of double rocker mechanism, thus drives drive crank reciprocally swinging; The driven rocking bar 10-1 of double rocker mechanism is connected with gear enlarger, thus sword belt 14 reciprocating motion of driven wheel enlarger (driven rocking bar does not directly contact with sword belt, and therefore driven rocking bar drives sword belt to move indirectly).
Described spatial ellipsoid mechanism comprises one and (is generally motor by dynamical element, omit and do not draw) spatial ellipsoid 6 that drives and a roller 21, the outer wall of spatial ellipsoid offers a circle groove 6-1, one end of roller 21 is fixed on described drive crank 7, the other end with insert groove 6-1 and and groove fit.The rotating shaft 6-2 two ends of spatial ellipsoid are arranged on the base plate 1-1 of casing by bearing 5, bearing block 3 and bearing cap 4, the outline line of groove is determined as required, usually, the rotating shaft of described spatial ellipsoid and the rotating shaft 8 of drive crank and axle sleeve 2 are arranged vertically.When spatial ellipsoid rotates, groove forces roller reciprocally swinging in the horizontal direction, thus drives drive crank reciprocally swinging, and usually, the diameter larger portion position of described groove in the middle part of spatial ellipsoid is offered.
Described gear enlarger comprises intermeshing sector gear 11 and takes turns 15 and described sword belt 14 with pinion 17, intermeshing bevel gear wheel 12-1 and bevel pinion 12-2, intermeshing sword belt.Sector gear is fixedly connected with described driven rocking bar, pinion is connected (diameter of pinion is less than bevel gear wheel) by vertical shaft 16 with bevel gear wheel, vertical shaft is arranged in longitudinal axis sleeve pipe 1-3, the bottom of vertical shaft is arranged on the base plate of casing by end cap 18 and bearing, bevel pinion and sword belt are taken turns and are connected (diameter of bevel pinion is less than sword belt takes turns) by transverse axis 13, transverse axis is arranged in transverse axis sleeve pipe 1-5, one end that transverse axis sleeve pipe is taken turns near sword belt is provided with transparent cover 1-6, and bevel gear wheel and bevel pinion are arranged in elbow 1-4.
Described double rocker mechanism comprises described drive crank 7, connecting rod 9 and described driven rocking bar 10-1 successively, the two ends of connecting rod respectively with drive crank and driven rocking bar hinged.One end of drive crank is installed in rotation on (casing cover cap is on base plate) between the base plate 1-1 of casing and casing 1-2 by rotating shaft 8, bearing and stifle 20, the other end of drive crank and the hinged of connecting rod.One end of driven rocking bar is installed in rotation between the base plate of casing and casing by elevating arc axle 10, bearing and end cap 19, the other end of driven rocking bar and the hinged of connecting rod.Described drive crank takes the shape of the letter U opening shape, and spatial ellipsoid is positioned at the U-shaped opening of drive crank thus saves space, and described roller is fixed on the U-shaped opening inwall of drive crank.The one-body molded support arm having two levels to stretch out on the outer wall of described elevating arc axle, two support arms form an angle mutually, and (angle is determined as required, such as 90-120 degree), one of them support arm is as described driven rocking bar 10-1, and another support arm 10-2 is fixed wtih described sector gear 11.
The utility model is by acting on the drive crank 7 of double rocker mechanism by spatial ellipsoid, export the characteristics of motion needed for weft insertion device, this rule is by the amplification of gear enlarger, and final sword belt can obtain wefting insertion rule of good performance, completes wefting insertion action.
