Description
Technical field
The present invention relates to a kind of warp knitting machine, it has a body and at least one axially extended bolster that is used for the circle forming bar, and this bolster is rotatably mounted and fix with respect to a mechanical component of locating regularly with body on axis direction.
Background technology
For manufacturing needles fabric in a warp knitting machine, must make the mutual relative motion of circle forming, so that form coil.A kind of like this motion should be narrated by sley bar pin (Legenadel).Similar moving link but also be present in other the circle forming.
When lopping, must make the sley bar pin both swing space between the pin that passes between the knitting needle, also must move perpendicular to this, just be parallel to ranks that wherein are furnished with knitting needle.The last motion that is parallel to bolster is caused by a jacquard weave transmission device or a jacquard weave drive unit.First kind of motion produced by following method: make bolster back rotation on certain angular range.Fixing lopping tool bar on this bolster finally is fixed with looping tool strickle on these bars.
Looping tool strickle must be positioned in the knitting machine very accurately, so that stop the collision that circle forming takes place in knitting process.Bolster can be fixed on axis direction exactly.Bolster must fix in the axial direction like this, makes bolster come back rotation around angular range recited above, so that can a kind of corresponding oscillating movement be delivered on the looping tool strickle by connecting rod.Bolster is for example controlled by a crank gear.
In addition bolster must also can be regulated on axis direction, and its position with respect to body must be able to be adjusted exactly in other words.The structure of the bearing block of always using before this makes is relatively complicated.Bolster passes through a needle roller bearing support separately in a wallboard, and this wallboard is connected with body.Needle bearing has ring in, and ring is made up of a kind of sleeve of accurate cooperation in this.This sleeve at one end has the line of rabbet joint, and stretches from the position of bearings in the midfeather in a side.One clamping ring encloses to start with and is clamped on the axle.Between a side of clamping ring and midfeather, be provided with a thrust bearing.Opposite side in this position of bearings has another thrust bearing, and it moves by the ledge that cooperates sleeve.Be provided with another clamping ring on its next door, it is in that one side has a fine thread towards the position of bearings, and this fine thread has a threaded collar.Utilize this clamping ring to make and cooperate sleeve in the fluting position, to be clamped on the bolster.If threaded collar is rotated towards thrust bearing, that just makes described bolster at axial restraint and maintain.Be positioned at the clamping ring opposite, that be fixed on the axle and be pulled to a described thrust bearing in this case, and threaded collar applies a counter-pressure and bolster is clamped.All parts must be made with high relatively quality of fit at this.A kind of like this bearing has determined its mounting cost higher relatively.If thrust bearing does not meet specialty and installs with requiring, their wearing and tearing in advance so.This requires again to increase and repairs.When repairing, must bolster be pulled out from the position of bearings, so that can change corresponding bearing with high relatively cost.
Summary of the invention
Task of the present invention is, make bolster easily axial restraint live.
Described task solves in a kind of warp knitting machine that starts the type of mentioning as follows: bolster is connected with mechanical component by a torque rod at axial direction.
Therefore can realize the axial restraint of bolster simply with respect to body.Torque rod can itself rotate, and also changes its length indistinctively.In this case, people consider the following fact: bolster just rotates a less relatively angular range in a kind of knitting process.If people for example are provided with torque rod like this so that it does not rotate in the centre of this angular range, so torque rod load in the knitting process less relatively.Though torque rod itself has distortion in each knitting process.But necessary for this reason power can be ignored, and the bearing friction in the thrust bearing that exists has not especially in the past had.
Torque rod is preferably made by a kind of spring material.If there is not external force, then spring material turns back to its original shape again.Spring material is used for realizing distortion.
At this advantageously, torque rod is made by spring steel.Can so come to determine the size of torque rod: it allows, and bolster is desirable to rotatablely move, and does not change the axial location of bolster.
Torque rod is preferably in the central axis position of bolster and acts on bolster.Utilize this organization plan, torque rod is maintained fixed motionless in knitting process, that is to say that it does not change its position.It still provides necessary axial support.
The length of torque rod is preferably at least 10 times of its maximum gauge.The material of considering torque rod is selected the ratio of length and diameter like this, makes it possible to achieve that bolster is desirable to rotatablely move.Simultaneously by coordinating be used to guarantee within the angle range of permission, the not twist axial shortening of bar of length and diameter.
Torque rod preferably has a kind of circular cross section.Therefore the location by angle of torque rod does not recur when mounted, and what acts on, and assembling has been simplified.
The torque rod best shape ordinatedly, force transmitted or non-disconnectable turning up the soil be connected with bolster.Bolster " is fixed " on axis direction with torque rod be connected, thereby make torque rod not only can bear bolster pressure, but also can bear the pulling force of bolster.Even on the direction of rotation of bolster, a kind of fixedly connected also be favourable, this has stoped and friction occurred.
Torque rod preferably is connected with a cup-shaped bearing, and this bearing is sleeved on the end of bolster.Therefore a kind of big relatively connection geometry is arranged, and this makes torque rod fixing easier on bolster.Torque rod for example can be inserted in the bottom of cup-shaped bearing, and welding is fixed there.A kind of like this connection can be made outside warp knitting machine relatively easily.In the time of in being encased in warp knitting machine, just also need less relatively installation process.
One fixture preferably acts on the bolster by a peripheral wall of bearing.For fixture, for example can be meant a kind of pinching screw, with this screw the cup-shaped bearing is clamped on the periphery of bolster.Also can use a kind of screw, this screw is screwed in the bolster.
Torque rod preferably is connected with a bearing-surface, and this bearing-surface can be adjusted with respect to mechanical component.Therefore can set up the axial location of bolster in body.For these needs are adjusted bearing-surface.A kind of like this adjustment can realize with different modes.
Stipulated in a kind of preferred design: bearing-surface passes through a spring-loaded on mechanical component, and is provided with a clamping device, and the power that it makes bearing-surface overcome spring is fixedly clamped on mechanical component.The position of bearing-surface can change easily by the following method: clamping device is clamped strong or weakly.This causes the bigger or less compression of spring again, and therefore causes the either large or small spacing of bearing-surface and mechanical component.People for example can adjust setting by make the power that compression takes place spring with it, therefore can not need under certain condition to have measured length or spacing exactly.
Bearing-surface preferably is bearing on the mechanical component by a bearing support to a spacing at interval swingably with spring.If more or less fastening spring makes not only rectilinear motion of bearing-surface so, and more or less swing.This allows meticulousr adjustment is done in the position of torque rod.
If torque rod is connected with bearing-surface between spring and bearing support, so especially like this.In this case, obtained a kind of big relatively gearratio, can make full use of this gearratio and be used to make torque rod to locate exactly.
Described torque rod preferably is connected with a jacquard weave transmission device, and this jacquard weave transmission arrangements is at an end place of warp loom.The jacquard weave transmission device then is used as the reference of torque rod position.This is favourable, because the jacquard weave transmission device is being controlled the motion of circle forming, it is important moving for this in the accurate position of bolster.Just can avoid a kind of sidewall that exceeds body.
Description of drawings
It is following that the present invention will be described in conjunction with the accompanying drawings according to a preferred embodiment.Accompanying drawing is depicted as:
Fig. 1: the three-dimensional view of the part of warp knitting machine;
The part figure who amplifies of Fig. 2: Fig. 1.
The specific embodiment
Fig. 1 represents a local figure of a warp knitting machine 1, and warp knitting machine has a body 2.Be provided with one at an axial end portion place of warp knitting machine 1 and be set to the jacquard weave transmission device or be set to the mechanical component of jacquard attachment 3, its makes looping tool strickle, for example sley bar of not being shown specifically move back and forth according to a kind of desirable pattern of knitwear.
Warp knitting machine has a plurality of bolsters 4,5,6, and they are bearing in wallboard 7,8, and 9 li, these wallboards are connected with body 2, for example realize by screw.Bolster 4,5,6 are bearing in wallboard 7,8 by bearing 10,9 li, these bearings allow bolsters 4,5,6 to rotatablely move, but are not bolsters 4,5,6 on its axial direction towards wallboard 7,8,9 supportings.
Unshowned sley bar recited above connects by circle forming bar and bolster 4,5,6.If make bolster 4,5,6 rotations, that just makes corresponding looping tool strickle swing.Oscillating motion is very not big, therefore when bolster 4,5,6 in less relatively angular range, for example can come back rotation enough less than 10 °.
Bolster 4,5,6 must locate to the axial direction of body 2 at it relatively accurately.This position must be adjustable.This position does not allow variation when work.
For this purpose, bolster 4,5,6 connect with a torque rod 11,12,13 respectively, and wherein the other end of each torque rod 11,12,13 is connected with jacquard attachment 3.Therefore jacquard attachment 3 has stipulated bolster 4,5, the reference position of 6 axial location.
As seen, at jacquard attachment 3 and bolster 4,5, do not have sidewall paneling between 6.But bolster 4,5,6 directly is bearing on the jacquard attachment 3.
Fig. 2 has represented torque rod 11,12, the enlarged drawing of 13 coupling parts, and a side and bolster 4,5,6, opposite side is connected with jacquard attachment 3.
With the torque rod 11 coefficient plates 15 of bolster 4 on fixed a bearing-surface 17.This bearing-surface 17 is bearing on the bearing support 18 at its lower end, and carries out screw fixed with plate 15.Bearing-surface 17 can be around little angle of bearing support swing.Bearing-surface 17 is located by a spring 19 in the top, for example a helical compression spring or a disc spring group are bearing on the plate 15.This spring is passed in screw 20 guiding, and the power that this screw overcomes spring 19 is clamping bearing-surface 17 on the direction of plate 15.The size of spring 19 should make it deform by tightening or unclamping screw 20, but the power that produces can't be owing to warp knitting machine 1 work the time is out of shape.
Described two other torque rod 12,13 has screw lid 21,22 at its place, end towards plate 16, utilizes this screw lid that it is tightened on the screw thread 23,24,16 li direction upper process towards bolster 5,6 of these screw thread slave plates.Torque rod 12,13 can for example weld with screw lid 21,22.
Each torque rod 11,12,13 has a cup-shaped bearing 25 at its place, end towards bolster 4,5,6 separately, and it is set on the axial end portion of bolster 4,5,6 separately.Bearing 25 has a plurality of screw holes 26 in its peripheral wall, these holes are passed in pinching screw guiding, with this pinching screw bearing 25 is clamped on the circumference of bolster 4,5,6 separately.Torque rod 11,12,13 weld respectively or bond with bearing 25, more precisely at the center of bearing 25 bottoms, thus torque rod 11,12,13 roughly with bolster 4,5,6 axis is consistent.Because bearing 25 is fixedly clamped respectively on the circumference of bolster 4,5,6 separately, that is to say and realized fixedly connected between torque rod 11 and bolster 4 on the one hand; Because torque rod 11,12,13 pass through plate 15,16 with jacquard attachment 3 connects, and has therefore guaranteed that bolster 4,5,6 is to the sure clear and definite location of jacquard attachment 3 separately.This position can be adjusted by means of bearing-surface 17 (for bolster 4) or by means of screw lid 21,22 (for bolster 5,6).
Bolster 4,5,6 rotate about 1 ° to 5 ° with rotatablely moving of a kind of vibration in a knitting process.Torque rod 11,12,13 can receive a kind of so little rotatablely moving without difficulty, even a kind of like this torsional load repeats when operation very frequently.If torque rod 11,12,13 is made of spring steel, that just especially like this.
