Description
(1) technical field
The utility model relates to a kind of textile machine, particularly a kind of chemical-fibres filaments winding apparatus winding head chuck axis swelling device that is applied to.
(2) background technology
The continuous yarn spinning winding head is the key equipment that technology content is the highest, manufacture difficulty is maximum in the continuous yarn spinning field.And chuck axis is the critical component in the winding head.Its performance is directly connected to the success and the failure of winding head.Winding head is as follows to the concrete technological requirement of chuck axis:
Winding speed when a, chuck axis are used for the FDY coiling can reach 6000 meters/minute, and promptly the maximum speed of revolution of chuck axis is 17362 rev/mins.This just requires swelling device must satisfy the requirement for dynamic balance of chuck axis;
B, swelling device should possess frequently the function of stepping up, unclamping and higher reliability.
The chuck axis swelling device of prior art as shown in Figure 1, it comprise the chuck axis 8 of hollow cylindrical structure ', be sleeved on fixed muffle 4 on the chuck axis body ', in the annular housing that constitutes jointly by chuck axis 8 ' outer ring surface and fixed muffle 4 ' inner ring surface, be spaced successively by by 24 little skewbacks 1 ', 24 tensioner projections 2 ', the tensioner assembly of 48 thin stage clips 6 ' form and piston ring 5 ', the bossing on 24 tensioner projection 2 ' tops is installed on respectively in the through hole that processes around fixed muffle 4 ' wall; Be processed with on the chuck axial wall that a plurality of pressurized airs that are connected with the annular housing that is made of jointly chuck axis outer ring surface and fixed muffle inner ring surface are advanced, round 7 '.Its principle of work is: when chuck axis 8 ' when being in the coiling mode of operation, the bossing on tensioner projection 2 ' top the little skewback 1 that matches with it ' and stage clip 6 ' effect under move up by the through hole on fixed muffle 4 ' wall, be sleeved on fixed muffle 4 ' on paper web 3 ' tensioner; After coiling work is finished, chuck axis 8 ' stop the rotation, pressurized air enters the chuck axis inner chamber by air valve, afterwards via a plurality of pressurized airs that process on the chuck axial wall advance, round 7 ' enter in the annular housing that constitutes jointly by chuck axis outer ring surface and fixed muffle inner ring surface, by piston ring 5 ' displacement make stage clip 6 ' compression, and then make tensioner projection 2 ' whereabouts, unclamp paper web 3 '.
The main weak point of above-mentioned prior art is: number of parts is many, processing difficulties, assembling are loaded down with trivial details, and the requirement for dynamic balance when being difficult for satisfying the chuck axis high-speed operation.
(3) summary of the invention
The purpose of this utility model provides with regard to being to overcome above-mentioned weak point of the prior art that a kind of structure is more reasonable, amount of parts obviously reduces, is easy to assemble and be more prone to satisfy the chuck axis swelling device of requirement for dynamic balance under the chuck axis high-speed cruising.
The purpose of this utility model can realize by following measure:
Chuck axis swelling device of the present utility model comprise the hollow cylindrical structure chuck axis, be sleeved on the fixed muffle on the chuck axis body, in the annular housing that constitutes jointly by chuck axis outer ring surface and fixed muffle inner ring surface, be aligned in sequence with many group tensioner assemblies; Wherein every group of tensioner assembly is all by being processed with the slip ring of a plurality of axial chutes along its periphery and forming with the tensioner projection that card is placed in each axial chute that concerns of running-fit respectively; The ramp structure of the bottom surface of described tensioner projection for matching with the axial chute bottom surface, the bossing on its top is installed in the through hole that processes around the fixed cover barrel, and the height of its bossing is greater than the wall thickness of fixed muffle; Between the adjacent slip ring in front and back, be provided with push rod; In the cavity of chuck axis, the piston rod that one its front end is provided with piston is installed by fixed mount, the end of piston rod is equipped with rear pressing cover, the ring edge sleeve of rear pressing cover is contained in the annular housing that is made of jointly chuck axis outer ring surface and fixed muffle inner ring surface, and contacts with slip ring; Between fixed mount and piston, be provided with spring; In the leading section cavity of the annular housing that constitutes jointly by chuck axis outer ring surface and fixed muffle inner ring surface, lay retracing spring.
The length of the projection of tensioner described in the utility model is less than the length of axial chute; The spring that is arranged between fixed mount and the piston is a dish-shaped spring.
Principle of work of the present utility model is as follows:
During the winding head normal winding, there is not pressurized air to enter in the cavity of chuck axis, compressed slip ring by the disk spring of pretension by the rear pressing cover that is installed in piston-rod end, and the tensioner projection that is installed in the slip ring axial chute is moving up by the through hole on the fixed cover barrel under the effect of slip ring inclined trough surface, with the paper web tensioner that is sleeved on the fixed muffle, and the power transmission of every group of tensioner inter-module all is to realize by the push rod that is arranged on therebetween; After coiling work is finished, chuck axis stops the rotation, pressurized air enters the chuck axis inner chamber by air valve and promotes the elastic force that piston overcomes the dish spring rear pressing cover that is installed in piston-rod end is retreated, slip ring in the tensioner assembly retreats under the effect of retracing spring, and then make the tensioner projection fall, unclamp paper web, promptly finish the winding process of a continuous yarn spinning.
Because the utility model adopts an end piston and one group of dish spring to replace a plurality of piston rings and stage clip in design, and adopt the slip ring that is easy to process to substitute a plurality of little skewbacks, not only make part processing become more easy, main is because the minimizing of parts makes chuck axis be more prone to satisfy dynamically balanced requirement under the high-speed cruising.
