Abstract
The invention relates to a traverser of guide bar, consisting of a service motor and a locomotory apparatus. The locomotory apparatus consists of a main locomotory apparatus and an auxiliary locomotory apparatus; the auxiliary locomotory apparatus is fixed on the outer side of the main locomotory apparatus in a parallel way; the service motor is positioned on a bearing seat of the main locomotory apparatus; a retractable shaft of the auxiliary locomotory apparatus is fixedly connected with a pushing rod shaft of the main locomotory apparatus through a connecting rod. As the pushing rod shaft and a ball screw are on the same axis and the auxiliary locomotory apparatus is arranged on one side of the pushing rod shaft and connected with the pushing rod shaft through the connecting rod, the torsion on the pushing rod shaft is removed by the retractable shaft and is no longer output, and the traversing error of the pushing rod shaft is reduced due to diminished gap between the ball screw and a ball nut, thereby improving the precision and lengthening the service life of the traverser; meanwhile, the ball nut and the ball screw are arranged in a sealed sleeve, which is not only good for ensuring product quality but also good for maintaining and preventing dust from entering, further with the advantages of low cost, simple and compact structure, etc.
Description
Technical field
The present invention relates to the guide bar shogging device on a kind of warp knitting machine, particularly warp knitting machine, belong to field of textile machinery.
Background technology
The control device of the guide bar shogging device on original warp knitting machine is made up of floral disc or chain piece, this device have slow, the traversing distance of speed little, ring the changes on slow, change that colored cost is big, circulation line number is few, control sley bar number is few, transverse movement precision is poor (accumulated error is arranged), complex operation, take up room big and shortcoming such as noise is big.And the control device of the guide bar shogging on the existing warp knitting machine mainly is made up of servomotor, screw mandrel, nut and push rod, and nut sleeve is contained on the screw mandrel, Yi Bian push rod one end is fixedlyed connected with nut, the push rod other end is connected with sley bar.Nut can not rotate with screw mandrel because of being fixed on the push rod parallel with screw mandrel, but can be along the screw mandrel moving linearly, so, when servomotor control screw mandrel rotates, can make nut drive push rod and control the traversing of sley bar, overcome above-mentioned shortcomings such as the traversing distance of original tricot machine comb racking-movement device is little, but because this device is too simple, the feed screw nut is directly exposed, is unfavorable for maintaining; The moment of torsion that screw mandrel rotates also can have influence on the push rod moving linearly through nut, simultaneously not only because of push rod and screw mandrel disalignment but also the further adverse effect that strengthens this moment of torsion of meeting; The dust that is scattered has more quickened the wearing and tearing of screw mandrel and nut; And then make the back lash increase between screw mandrel and the nut and cause guide bar shogging inaccurate, make useful life shorter.
Summary of the invention
The objective of the invention is in order to solve the weak point of guide bar shogging control device on the above-mentioned existing warp knitting machine, provide a kind of reasonable in design, help maintaining enclosed construction, the screw mandrel moment of torsion do not leak, the guide bar shogging device of transverse movement precision height, long service life.
Guide bar shogging device of the present invention comprises servomotor and locomotory apparatus, it is characterized in that locomotory apparatus is made up of main motion device and auxilliary locomotory apparatus, the auxilliary parallel outside that is packed in the main motion device of locomotory apparatus, servomotor is contained on the bearing block of main motion device, and auxilliary locomotorial telescopic shaft is fixedlyed connected with the push rod shaft of main motion device through connecting rod.
Described main motion device comprises sleeve, bearing block, ball screw, ball nut, push rod shaft and end cap, described bearing block and end cap are packed in the sleeve two ends respectively, place the ball-screw in the sleeve to go out and be contained on the bearing block through the leading screw shaft extension, ball nut is sleeved on the ball-screw, push rod shaft one end places in the sleeve and the cavity through being provided with is sleeved on the ball-screw and fixedlys connected with ball nut, and the push rod shaft other end stretches out end cap from the sleeve other end and is connected with sley bar.
Described auxilliary locomotory apparatus comprises telescopic shaft, supporting mass, linear bearing and connecting rod, described telescopic shaft one end is installed in the supporting mass parallel with the main motion device through linear bearing, the telescopic shaft other end is connected with connecting rod, and the connecting rod other end is connected with the push rod shaft of stretching out end cap of main motion device.
For the ease of assembling, can between two axis holes of connecting rod, offer the fastening seam of a connection, the connecting rod of fastening seam both sides is provided with the screw that fastening bolt is installed.
During installation, the sleeve of servomotor and main motion device is fixedly mounted on the frame, and the servomotor output shaft is connected with the lead screw shaft of main motion device, and the push rod shaft of main motion device is connected with sley bar.
During work, servomotor drives ball-screw and rotates, the ball nut drive push rod shaft that is sleeved on the ball-screw is done straight reciprocating motion, because of a side of push rod shaft is equipped with auxilliary locomotory apparatus and interconnects through connecting rod, torsion on the push rod shaft is offset by telescopic shaft and no longer output, be contained on same the axis because of push rod shaft and ball-screw again, when ball nut is moved on ball-screw stressed evenly, motion steadily helps reducing the wearing and tearing and the fit clearance of ball-screw and ball nut, reduced the error of the transverse movement that push rod shaft produces because of gap between ball-screw and the ball nut.Improve transverse movement precision and increase the service life; Simultaneously, ball nut and ball-screw are installed in the sleeve of sealing, have both helped guaranteeing that ball-screw and push rod shaft can help maintaining again and prevent that dust from entering on same axis, more help industrially producing the parts product of guaranteeing quality.It is low also to have cost, advantage such as simple in structure and compactness.
