Abstract

The utility model discloses an eccentric compensating error type cradle relating to an innovation for improving the parallelism of a cradle drafted and compressed by a ring spinner. The cradle comprises a cradle base (1), a cradle body (2), a cradle base and cradle body hinge axis, an upper roller holding mechanism and a pressurizing depressurizing mechanism. In the cradle base and cradle body hinge axis, the original cylinder axis is changed into an eccentric axis (3). When the eccentric axis (3) is unscrewed, the cradle body (2) can swing properly relative to the cradle base (1), thereby eliminating accumulated errors caused by related parts of the cradle on the parallelism. The cradle has the advantages that the parts can be manufactured with economic accuracy, and various cradles with very high parallelism can be produced to satisfy the increasing requirement on the spinning quality.

Description

Eccentricity compensation error formula reel cage

Technical field the utility model belongs to spinning machinery, relates to the improvement that improves the ring spinner drawing-off pressurized cradle depth of parallelism.

The national sector standard of the various drawing-off pressurized cradle of background technology (FZ/T 92036-2007, FZ/T 92072-2006) all will be gone up the depth of parallelism of bottom roll and classify the first the key technical indexes as, the importance of the visible depth of parallelism.Therefore each reel cage production scientific research institution all drops into a large amount of manpower and materials for improving the depth of parallelism both at home and abroad, and develops the numerous reel cages that are intended to improve the key technical indexes such as the depth of parallelism.Main achievement to the depth of parallelism in this a large amount of research has following several types: the one, adopt the self-level(l)ing line; Facts have proved that this mode is limited for the raising effect of the depth of parallelism; In spinning process, to swing from timing simultaneously owing to top roller; Thereby two coring bars to it gripped will produce adverse influence, and wherein the instantaneous drafting multiple of a coring bar can increase and cause details, the instantaneous drafting multiple of another coring bar of face to reduce and cause slubbing.Therefore this self-paralleling structure is not a developing direction.The 2nd, the accuracy of manufacture that improves the reel cage part finally guarantees the depth of parallelism.The accuracy of manufacture that employing improves constantly part certainly will improve constantly production cost.And part always has error, so not parallel problem always exists.The 3rd, adopt compensation principle to adopt the way of compensation that it is eliminated the accumulated error of each correlated parts, thereby can produce the high reel cage of the depth of parallelism, this is the developing direction that improves 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 are produced the high reel cage of the depth of parallelism.This is a kind of breakthrough innovation.But still there is following deficiency in this patent scheme: the one, and the scope of application is little, is only applicable to the lever reel cage, then can't adopt for the reel cage of other numerous types.The 2nd, strengthen production cost thereby will increase part.The 3rd, want soldering to fix after the adjustment, thereby cause the expensive deficiency that waits of taking a lot of work.

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 utility model is to the deficiency of prior art; A kind of new compensating error scheme is provided; Its both available economic accuracy is made reel cage part, can not increase number of parts basically again, the design that can be basically the depth of parallelism of various reel cage can both be increased substantially applied widely.

The technical solution of the utility model is this eccentricity compensation error formula reel cage that is 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, and the one, base center axis (O), the 2nd, the central axis (O of eccentric part ₁), when being benchmark eccentric rotation axis (3) with base center axis (O), the central axis (O of eccentric part ₁) will axis (O) be that radius rotates with the eccentric throw around the base center.When the positive and negative angle that turns eccentric shaft (3) during less than half cycle, then above-mentioned central axis (O ₁) will axis (O) be that radius is swung with the eccentric throw around the base center.The cylinder that the base center axis (O) of eccentric shaft (3) is located cooperates with the hole of rocking arm and base (1) both sides; One side opening of reel cage body (2) is cooperated with the cylinder that the base center axis (O) of eccentric shaft (3) is located; And another side opening cooperates with the cylinder of eccentric part; When turning eccentric shaft (3) again, reel cage body (2) just can be done suitably swing with respect to rocking arm and base (1).Thereby just can eliminate each relevant part of reel cage to the accumulated error that the depth of parallelism causes, make the depth of parallelism of bottom roll reach high level.After reel cage is just adorned and accomplish compensation adjustment, again that eccentric shaft (3) is fixing with reel cage body (2) or rocking arm and base (1), eccentric shaft (3) is no longer changed with respect to the angular position of reel cage body (2) or rocking arm and base (1) get final product.This scheme is exactly the scheme of eccentricity compensation error.

The advantage and the good effect of the utility model are: can adopt economic accuracy to make the reel cage part and produce the high various reel cage of the depth of parallelism, to satisfy the requirement that spinning quality improves constantly.

Specific embodiment instance 1 combines accompanying

drawing

1,2 explanations as follows: the rocking arm and base of the reel cage that will just install (1) is fixed on the back shaft of the testboard that is equivalent to drafting device for spinning machine (containing roller stand, bottom roll, back shaft), loads onto top roller and makes reel cage be in pressurized state.Be positioning reference in order to bottom roll again, and the measuring tools (referring to the industry standard FZ/T 92036-2007 of drawing-off pressurized cradle, FZ/T 92072-2006) that the consistent dial gauge at a distance of an about ingot distance of two adjustment is housed are measured the depth of parallelism of top roller to bottom roll.When two dial gauge indicated values in the above-mentioned measuring tool are inequality, should turn eccentric shaft (3), at this moment reel cage body (2) is being with top roller to swing, and the indicated value of two dial gauges on the measuring tool will constantly change.When the indicated value of two dial gauges was identical, it is parallel fully that just bottom roll is gone up in expression, at this moment the compensation adjustment of reel cage just accused and accomplish.With nut eccentric shaft (3) is tightened on the reel cage body (2) then, it can not be relatively rotated with reel cage body (2) get final product.

Because reel cage reel cage body (2) when compensation adjustment will do an amount of swing with respect to rocking arm and base (1), so an amount of gap need be set in their parts that matches.It is moving to prevent again simultaneously that reel cage body (2) from along eccentric shaft (3) bigger string taking place axially.This can be provided with pad (4) between reel cage body (2) and rocking arm and base (1).Also can directly produce bulge loop and replace pad (4) at the periphery in the hole that rocking arm and base (1) or reel cage body (2) and eccentric shaft (3) match.

Instance 2 combine accompanying
