Abstract

The existing oscillator for an electronic jacquard, which drives a swing arm by an eccentric wheel mechanism, having the defects of complicated structure, high maintenance cost, large impact on a dead point, etc. The utility model provides the oscillator for an electronic jacquard, one end of the swing arm 9 is fixedly arranged on a pendulum shaft 8 and the other end is provided with a shaft parallel to the swing arm; a rotor 4 is arranged on the shaft, the rotor as a thimble butts on a cam 1 and the cam is fixedly arranged on a camshaft 2. When the utility model is operated, the camshaft drives the cam to rotate, transfers a dynamic force by the rotor and leads the rotor to drive the swing arm to swing depending on the pendulum shaft. The utility model provides the oscillator for an electronic jacquard, which drives the swing arm by a cam mechanism, leading the oscillator for an electronic jacquard to run stably, working without impact vibration, and reducing mechanical abrasion and maintenance cost.

Description

The pendulous device of electronic jacquard machine

Technical field the utility model relates to a kind of pendulous device of electronic jacquard machine, is used to handle the knee-action of griffing on the grape jacquard.

The pendulous device of the existing electronic jacquard machine of background technology has generally adopted eccentric rod gear.Concrete structure is eccentric wheel to be arranged with the coaxial installation of eccentric shaft on it and driving shaft, and eccentric wheel cooperates with the outside burr, and this ring is connected on the swinging axle through a rocking arm.Ring is pushed action swing when eccentric wheel rotates, thereby makes swinging axle do back and forth twisting, makes the fork swing that is installed on the swinging axle and handles and griffe up and down reciprocatingly to move.In addition, the pendulous device of the electronic jacquard machine of this structure be the needle selecting device both sides griffe respectively handle at two ends with two cover eccentric rod gears.The pendulous device of the electronic jacquard machine of this structure exists some shortcomings, mainly be complex structure, maintenance cost height, again because eccentric rod gear exists and to give up the idea,, parts are worn and torn easily and cause the vibration abnormal sound of machine so when running up, can produce greater impact.

Summary of the invention is at above-mentioned deficiency, and technical problem to be solved in the utility model is exactly to make the pendulous device of electronic jacquard machine eliminate the big impact that is produced and make its designs simplification when high speed rotating.

The pendulous device of electronic jacquard machine provided by the utility model has rocking arm, and an end of rocking arm is fixedly mounted on the balance staff, the other end is installed an axle parallel with rocking arm, a rotor is installed on the axle, and rotor withstands on the cam as thimble, and cam is fixedly mounted on the camshaft.During work, camshaft drives cam rotation, through the rotor transferring power and make rotor banding shake arm to swing according to balance staff.

The pendulous device of electronic jacquard machine provided by the utility model, there are two rotors 4,4 ' to withstand on symmetrically on the cam 1 as thimble, two rotors are related separately have rocking arm 9,9 ' and balance staff 8,8 ' form two groups up and down, two forks up and down of being installed on two balance staffs are connected with the same end of griffing same group of needle selecting device both sides separately.Making a cam handle two through two same group rotors, rocking arm and balance staff griffes.

The pendulous device of electronic jacquard machine provided by the utility model respectively is equipped with a Connection Block 3,3 ' on two rotors 4,4 ' armature spindle, with two pull bars 6,6 ' two Connection Blocks are led mutually two rotors are pressed closer on cam.Generally speaking, pull bar is made of screw rod and nut, and has at least an end to be with a spring 7,7 ' so that the rotor elasticity certain to compressing of cam on every pull bar.

The pendulous device of electronic jacquard machine provided by the utility model drives rocking arm with cam mechanism, the pendulous device of electronic jacquard machine is operated steadily, do not have impact shock when working, and has reduced mechanical wear and maintenance cost.Especially when with a cam when two rotors handle that two balance staffs drive the forks swing up and down, more make the pendulous device compact conformation of electronic jacquard machine, two moving row of balance staffs reliable synchronously.

Description of drawings Fig. 1 is the front view of the utility model one embodiment;

Fig. 2 is an A-A expanded view among Fig. 1.

The specific embodiment as shown in Figure 1, 2, there is cam 1 to adopt bulging joining sleeve to be installed on the camshaft 2, there are up and down two rocking arms 9,9 ' be installed in up and down on two balance staffs 8,8 ' with the obvolvent fastening means respectively, there are up and down two double-row roller bearings 4,4 ' be installed in up and down on two armature spindles as rotor, article two, armature spindle pass respectively respectively install behind the hole on the end of two rocking arms 3,3 ', two Connection Blocks of a Connection Block with two screw rods 6,6 ' and spring 7,7 ' tension rotor is pressed closer on cam.Connection Block is and nut 5 that rotor uses, 5 ' cylindrical is installed movingly.The pendulous device of the electronic jacquard machine that present embodiment provides, with a cover cam rotation luffing mechanism, when camshaft 2 drives the continuous revolution of cam 1 do, transmission by upper rotor part 4 and lower rotor part 4 ', upper rocker arm 9 and lower shake-changing arm 9 ' swung up and down according to last balance staff 8 and following balance staff 8 ', order about balance staff simultaneously and do back and forth to twist and drive fork again and draw the work of griffing.Also be provided with simultaneously and comprise Connection Block 3,3 ', pull bar 6,6 ' and spring 7,7 ' rotor lead tight device, make rotor be close to cam and the synchronous coordination that guarantees to swing up and down is level and smooth and cushioning effect preferably arranged.
