Description

Eccentric compensating error type cradle

Technical field the invention belongs to spinning machinery, relates to the improvement improving the ring spinner draft pressurizing cradle depth of parallelism.

The national sector standard (FZ/T 92036-2007, FZ/T 92072-2006) of the various draft pressurizing cradle of background technology, is all classified as by the depth of parallelism of upper bottom roll as the first the key technical indexes, the importance of the visible depth of parallelism.Therefore domestic and international each reel cage production scientific research institution all drops into a large amount of manpower and materials for improving the depth of parallelism, and develops the numerous reel cages being intended to improve the key technical indexes such as the depth of parallelism.Main achievement for the depth of parallelism in this large quantifier elimination has following several types: one is adopt self-level(l)ing line, facts have proved the raising limited use of this mode for the depth of parallelism, simultaneously in spinning process because top roller will swing from timing, thus will adverse influence be produced to the two coring bars that it grips, wherein the instantaneous drafting multiple of a coring bar can increase and cause details, and the instantaneous drafting multiple of another coring bar of face can reduce and cause slubbing.Therefore this self-paralleling structure is not developing direction.Two is that the accuracy of manufacture improving reel cage part finally ensures the depth of parallelism.The accuracy of manufacture improving constantly part is adopted to improve constantly production cost.And part always has error, so not parallel problem always exists.Three is adopt compensation principle to adopt the way compensated to be eliminated the accumulated error of each correlated parts, thus can produce the high reel cage of the depth of parallelism, and this is the developing direction improving the depth of parallelism.

The patent No. is the Chinese patent of ZL200520034846.3, utilizes the principle of compensating error exactly, and available economic accuracy finished parts produce the high reel cage of the depth of parallelism.This is a kind of breakthrough innovation.But this patent formula still has the following disadvantages: one is that the scope of application is little, is only applicable to lever-type cradle, and the reel cage for other numerous types then cannot adopt.Two is will increase part thus strengthen production cost.Three is want soldering to fix after adjustment, thus causes expensive grade of taking a lot of work not enough.

The rocking arm and base reel cage body hingle shaft of existing various reel cage is cylinder axis in addition.

Summary of the invention the present invention is directed to the deficiencies in the prior art, a kind of new compensating error scheme is provided, it both can manufacture reel cage part with economic accuracy, substantially can not increase number of parts again, applied widely can substantially by design that the depth of parallelism of various reel cage can increase substantially.

Technical solution of the present invention is this eccentric compensating error type cradle being applied to ring spinner, comprise rocking arm and base, reel cage body, rocking arm and base reel cage body hingle shaft, top roller holding mechanism, add pressure relief means thereon, it is characterized in that: rocking arm and base reel cage body hingle shaft is eccentric shaft (3).

Eccentric shaft (3) has two central axis, one is base center axis (O), two is central axis (O1) of eccentric part, when with base center axis (O) for benchmark eccentric rotation axis (3) time, the central axis (O1) of eccentric part will be that radius rotates with eccentric throw around base center axis (O).When the positive and negative angle turning eccentric shaft (3) is less than half cycle, then above-mentioned central axis (O1) will be that radius swings with eccentric throw around base center axis (O).The cylinder at base center axis (O) place of eccentric shaft (3) is coordinated with the hole of rocking arm and base (1) both sides, by the cylindrical fit at base center axis (O) place of a side opening of reel cage body (2) and eccentric shaft (3), and the cylindrical fit of another side opening and eccentric part, when turning eccentric shaft (3) again, reel cage body (2) just can be done suitably to swing relative to rocking arm and base (1).Thus just can eliminate each accumulated error depth of parallelism caused about part of reel cage, make the level that the depth of parallelism of bottom roll reaches high.Compensation adjustment is completed after reel cage just fills, again eccentric shaft (3) and reel cage body (2) or rocking arm and base (1) are fixed, eccentric shaft (3) is no longer changed relative to the angular position of reel cage body (2) or rocking arm and base (1).This scheme is exactly the scheme of eccentric compensating error.

Advantage of the present invention and good effect are: economic accuracy can be adopted to manufacture reel cage part and produce the high various reel cage of the depth of parallelism, to meet the requirement that spinning quality improves constantly.

Detailed description of the invention example 11,2 is described as follows by reference to the accompanying drawings: be fixed on by the rocking arm and base (1) of the reel cage just installed on the back shaft of the testboard being equivalent to drafting device for spinning machine (containing roller stand, bottom roll, back shaft), load onto top roller and make reel cage be in pressurized state.Be positioning datum in order to bottom roll again, and the measuring tool (referring to the industry standard FZ/T 92036-2007 of draft pressurizing cradle, FZ/T 92072-2006) that two pieces of consistent dial gauges at a distance of about ingot distance of adjustment are housed measures the depth of parallelism of top roller to bottom roll.When piece dial gauge indicated value of two in above-mentioned measuring tool is not identical, should turn eccentric shaft (3), at this moment reel cage body (2) swings with top roller, and the indicated value of two pieces of dial gauges on measuring tool will constantly change.When the indicated value of two pieces of dial gauges is identical, just represents that upper bottom roll is completely parallel, at this moment the compensation adjustment of reel cage has just been accused.Then with nut, eccentric shaft (3) is tightened on reel cage body (2), makes it can not relatively rotate with reel cage body (2).

Because reel cage reel cage body (2) when compensation adjustment will do appropriate swing relative to rocking arm and base (1), therefore need to arrange appropriate gap in their parts that matches.Prevent reel cage body (2) from axially larger vibration occurring along eccentric shaft (3) again simultaneously.This can arrange pad (4) between reel cage body (2) and rocking arm and base (1).The periphery in the hole that also can match with eccentric shaft (3) at rocking arm and base (1) or reel cage body (2) directly produces bulge loop to replace pad (4).

Example 21,3 is only described as follows with example 1 difference by reference to the accompanying drawings: example 1 be for reel cage body (2) outside rocking arm and base (1) be the example how implementing to compensate at an interior class reel cage.This example is then for the embodiment of reel cage body (2) at interior rocking arm and base (1) class reel cage outside.When turning eccentric shaft (3), central axis (O1) equally also suitably can swing around central axis (O), and makes the accumulated error of reel cage be eliminated the object reaching compensation.And then itself and rocking arm and base (1) are fixed by the way of eccentric shaft (3) with riveted joint.

The structure of eccentric shaft (3) be not limited to Fig. 2,3 two kinds, can be diversified, its central axis more than two, also can play the object of compensation, but can increase manufacture difficulty.Maintenance eccentric shaft (3) way that operationally angular position is constant also can be varied, as being fastened on reel cage body (2) or rocking arm and base (1) with nut or screw, also can be riveted, be welded, be bonded on reel cage body (2) or rocking arm and base (1), also it can be made to be fastened on reel cage body (2) or rocking arm and base (1) by friction tight way upper etc.
