Background technology
The harness motion that warp thread is provided is the Core Feature of electronic jacquard machine.At present, domestic textile industry mainly adopts the electronic jacquard machine of following two kinds of shedding mechanisms for the basis.
A kind of is to be the big rocker structure of representative with Britain BONAS, as shown in Figure 1 (in the 4 groups of mechanisms that are arranged in parallel of only having drawn among the figure 1 group).Its operation principle is: continuous rotating crank 1 ' (two of 180 ° of distributions pairs of eccentric wheels each other) and connecting rod 3 ' driving lifting rocking bar 4 ' around back shaft 5 ' swing, and drive the upper and lower reciprocal harness motion of broaching tool 2 ' finish, since many broaching tool 2 ' lifting rocking bar 4 ' on the difference of relative back shaft 5 ' distribution radius, directly form the beveled of warp thread, structure is very simple.Its major defect is lifting rocking bar 4 ' structure huge (length is above 1 meter), and motion is impacted big, is difficult to adapt to the loom speed that improves day by day, and application is restricted.
Another kind is French STAUBLI concentric shafts structure, as shown in Figure 2.Operation principle is: continuous rotating conjugate cam 2 ", 6 " is by fork 1 ", 5 ", axle 3 " and outer shafts 4 " and lifting rocking bar 9 in driving ", 10 " backswing, and " realize upper and lower reciprocating motion, i.e. harness motion by lifting connecting rod 8 " drive inside broach frame 11 " and broach for external bracing frame 12.Change and to lift connecting rod 8 " at lifting rocking bar 9 ", 10 " on pendulum radius, just can obtain needed beveled, the horizontal displacement of inside broach frame 11 ", broach for external bracing frame 12 " " is controlled by guiding rocking bar 7.
The major advantage of this concentric shafts structure is: (1) lifting rocker structure symmetrical balance, and the centre of form overlaps with the centre of gyration, and size reduces (the big rocking bar of BONAS relatively), and rotary inertia descends, and high speed performance significantly improves; (2) lift connecting rod 8 " be arranged in lifting rocking bar 9 ", 10 " centre of gyration both sides; the side that descends lift connecting rod 8 " deformation energy of stored return spring was converted into lifting rocking bar 9 before it was descended ", 10 " kinetic energy, help opposite side to lift connecting rod 8 " up; so both sides moment has mutual compensating action, and actual driving moment is reduced; (3) adopt conjugate cam 2 ", 6 ", can obtain desirable harness motion, satisfy the weaving process requirement to greatest extent as reciprocating driving link.Because this mechanism's advantage is outstanding, is the leading products of existing market.
Also there are some problems in the concentric shafts shedding mechanism: the one, inside and outside axle 3 ", 4 " and lifting rocking bar 9 ", 10 " are mutually nested, in addition the conjugate cam case 15 of oil bath ", complex structure, cost height; The 2nd, except that cam box 15 " whole shedding mechanism all be arranged in the inboard of knee wall plate, must be in case there was a mechanical failure with cam box 15 " even wallboard unloads, and maintenance process is very poor; The 3rd, the high-order power of whole harness motion (mainly refer to lift motion) is only provided by two groups of conjugate cams 2 of line contact ", 6 ", and the application point compact stress is very big, the stress condition very severe, and homemade cam is difficult to guarantee to use reliably; The 4th, the spring bearing of concentric shafts power intake will bear the powerful radial load of the power that lifts of lifting rocking bar 9 ", 10 " and conjugate cam 2 ", 6 " simultaneously, becomes the weak link of this mechanism and taking place frequently a little of fault.

2, be symmetrically distributed because of the relative main shaft of lifting rocking bar, front and rear connecting rods is opposite all the time to the force direction of eccentric wheel and main shaft, the main shaft force in radial is stressed poor of two eccentric wheels, its maximum 1/3 of not enough big rocker structure of making a concerted effort, it is more then to descend than the concentric shafts structure, so the stressed excessive problem of power intake main shaft bearing that the concentric shafts structure exists has obtained radical change.
3, the lifting rocking bar adopts big corner small scale structures and the supporting of minor axis freely-supported, and rotary inertia is littler, 1/4 of its big or small not enough concentric shafts structure, than big rocker structure by a larger margin decline is arranged then, the also corresponding raising of mechanism's rigidity simultaneously, so high speed performance is better, moves more steady.
4, the upper end that lifts connecting rod can be regulated arbitrarily in the straight trough of lifting rocking bar and be equipped with the reading scale, thereby has the step-less adjustment function of opening amount, to satisfy the requirement of weaving process to openings of sizes to greatest extent.
5, the lifting rocking bar is designed to 60 ° of pivot angles, at this moment, lifts the reciprocating stroke and the pendulum radius value approximately equal of its upper link point on the lifting rocking bar of connecting rod, therefore, the scale that is used to regulate opening can be directly with the millimeter unit of doing, and is easy to use directly perceived.
6, compare with the concentric shafts structure, the lifting rocking bar that adopt to separate replaces complicated concentric shafts nested structure, and replace the accuracy of manufacture to require high and need the conjugate cam of oil bath with eccentric wheel, designs simplification, processing and assembly process process all improve, the cost reduction.
7, with the eccentric wheel that easily goes wrong and linkage arrangement outside two wallboards, and other part all can be finished dismounting under the situation of not dismantling wallboard, field maintenance is very convenient.
